recordconfirmed Between March and July 2026 Valar's NRC-suit post, 'CAT scan' claim intact, was tagged asking search engines not to list it
2026 · orig-061 · Valar Atomics

Valar's April 7, 2025 post 'Valar Atomics is Suing the NRC' contains the claim that holding Ward One's spent fuel for five minutes gives the same exposure as a CAT scan (orig-017). Read in late September 2026, the page carries a robots meta tag, 'noindex, nofollow', which asks search engines not to list it, and the site's page data marks it 'disableIndex: true'; no other Valar library post carries the tag. Internet Archive copies of the page from April 8, 2025 through March 23, 2026 have no such tag; copies from July 22 and August 25, 2026 have it. In every copy the claim's text is unchanged, and no correction or note has been added. The post is still listed in Valar's own library, so visitors to the site can still find it. The tag appeared some time after March 23, 2026. The record does not show who added it or why.

In plain termsValar's post with the 'CAT scan' claim is still on its website, word for word. Sometime between late March and late July 2026 the page was tagged asking search engines not to list it, while it stays on the company's own site. No correction or withdrawal of the claim was found. No statement of why the tag was added was found in public records as of late September 2026.
verified 2026-10-02: Second check, late September 2026: live page and Internet Archive captures of 8 Apr 2025, 24 Aug 2025, 22 Dec 2025, 26 Feb 2026, 23 Mar 2026 (no robots tag) and 22 Jul 2026, 25 Aug 2026 (tag 'noindex, nofollow') re-read; the CAT-scan sentence is identical in all; library data marks only this post 'disableIndex: true'. Match. Corrected in late September 2026: the headline now says the tag asks search engines not to list the post, and the absence of a correction is stated as 'no correction found'. Reworded 30 Sep 2026: the detail and the plain-language text.
analysisconfirmed Carbon site in brief: state lease for a nuclear campus approved; no build permits found; a Valar mining claim 2 mi south
2026-09 · csite-001 · Valar Atomics, Utah Trust Lands Administration, Carbon County

As of late September 2026: the Trust Lands board voted unanimously on 17 September 2026 to approve an 'Other Business Arrangement' with Valar Atomics on Section 16, T14S R11E, about five miles north of Wellington: 480 acres now, the other 160 if a National Guard lease is moved, 50 years plus two 25-year extensions, with an option to buy (csite-004, mine-011). The stated purpose is an integrated nuclear energy, advanced manufacturing, critical mineral refining and data center campus: high-temperature gas-cooled reactors, TRISO fuel manufacturing, hydrogen and synthetic fuels, desalination and steel. Separately, a Notice of Location names Valar Atomics Inc as locator of the 'RW 453' lode mining claim in Section 28, two miles south, located 12 September 2026; it is not yet in BLM's public claim layer, which the 90-day recording window allows (mine-453, dir-005). No county permit application, state DEQ permit or DOE/NEPA document for the Carbon site was found (csite-012, csite-020). Whether any NRC filing exists was not checked, and water-right filings were not searched. The only official actions found are the board's vote and the commissioners' 29 June support letter, which was not found on any Carbon County Commission agenda posted for its 6 May to 16 September 2026 meetings (mine-013, csite-026). No departure from the notice rules read was found (csite-005, csite-016, csite-018), but the first public document found naming Valar for the site was posted on 10 August 2026, and the April state review notice did not say nuclear (csite-032). Open questions: waste-storage framing (csite-008), the NRC route vs the CEO's 2025 stance, a one-test NEPA review vs a larger build-out, officials' praise of Valar's openness beside county agendas that did not name the site (disc-031), and a lode claim with no mineral stated (disc-003).

In plain termsIn short: the state has agreed to rent Valar about three-quarters of a square mile north of Wellington (the whole square mile later if a National Guard lease is moved, with an option to buy) for a future nuclear and industrial campus. Nothing has been built there, and no application for the permits that would allow building appears in the records we could check. The deal followed the notice rules we could check, but those rules kept the company's name and plan out of the first public notices, and the first public record found naming Valar for the site came about five weeks before the vote. Separately, a Notice of Location shows Valar has staked a mining claim two miles south. The next steps (a county permit, water rights, state and federal nuclear approvals) are where the public can still weigh in.
verified 2026-10-02: Re-checked in late September 2026 against the September memo (pp. 18-27), the 17 Sept transcript (motion; 'Is unanimous') and each cited fact. Corrected: the earlier 'Valar holds no mining claims there' is superseded by the Notice of Location (mine-453); 'critical mineral refining' added from the memo summary; NRC filing status now stated as unchecked, not as absent.
recordconfirmed Every Valar site on record (late September 2026): one test reactor, one lease, three pending BLM files, one unbuilt abroad
2026-09 · plan-017 · Valar Atomics, Bureau of Land Management, Utah Trust Lands Administration, Emery County

Built or operating: Ward 250 and its fuel lab at the San Rafael lab, Emery County; the company's design, machining and test shops in Hawthorne/Torrance, California. Used once: the NOVA test core at the National Criticality Experiments Research Center, Nevada, operated by Los Alamos in November 2025 (orig-008). Being acquired: the 112-acre Emery County parcel beside the lab (gov-022, loc-014). Lease approved: on 17 September 2026 the state trust-lands board approved a lease with purchase option for 480 acres of the section north of Wellington, with the other 160 acres to follow if the National Guard's lease there is moved (mine-011); no record read shows the lease signed. Applied for: three Bureau of Land Management cases, all in the Price Field Office, all 'Pending' in late September 2026: UTUT106784007 'Green River Gigasite Small Modular Reactor/Data Center' (10,270.61 acres, case date 13 February 2026, which Valar told The Washington Sun it no longer pursues, mine-008), UTUT106801248 'Project Beehive Small Modular Reactor/Data Center' (case date 13 April 2026, no acreage shown), and UTUT106833224, a distribution-line case with no name (entered 23 July 2026). NPR reported on 30 September 2026, citing a Valar proposal to federal regulators that NPR reviewed, that Project Beehive would cover over 9,000 acres of BLM land near Price with data centers, some 456 small reactors of 25 megawatts of electricity each, a fuel facility and nuclear-waste storage, with the first reactors in 2028; BLM's Utah office told NPR it had received an application and was reviewing it for completeness. The proposal itself was not found in public records. No BLM rights-of-way case names Valar outside Utah, and its other public layers show no Valar claims, notices, leases or permits (mine-030). Valar says it looked at more than 20 states (loc-001); no site in another state was found in any public record read.

In plain termsHere is the whole map as far as public records go. One small test reactor is running in Emery County, next to a fuel lab. The reactors are built in the Los Angeles area. Valar is buying land next to the Emery lab and has state approval to lease most of a square mile of state land in Carbon County. It has three pending cases with the federal land agency: the Green River site (over 10,000 acres; Valar says it dropped it), Project Beehive near Price (which NPR reports is planned for about 456 small reactors on over 9,000 acres) and a distribution-line right-of-way.
verified 2026-10-02: Checked in late September 2026: BLM's rights-of-way records re-checked for customer name Valar: three Utah cases, all Pending, Price Field Office; Green River 10,270.61 acres, case date 13 Feb 2026; latest modification 15 Sept 2026. Fixed: lease wording overstated (board approval; initial 480 acres; signing not found); Launch Pad wording corrected. Revised before publication (late September 2026): earlier fix note reworded (lease wording). Checked 2 Oct 2026: the NPR paragraph matches NPR's 30 September 2026 article as published (456 reactors, over 9,000 acres, 25-megawatt units, first reactors in 2028, BLM reviewing the application for completeness).
analysisconfirmed What holds up: DOE did authorize the reactor, the airlift was unfueled, DOE checked the fuel's shipping package, DOE rates TRISO fuel more resistant than ordinary fuel
2026-09 · safe-039 · Valar Atomics, U.S. Department of Energy

Claims tested and found supported by the record: DOE confirms Ward 250 is DOE-authorized and completed a zero-power criticality on 18 June 2026 (orig-010). The February 2026 airlift carried the reactor without fuel, and the fuel was to move separately from Nevada, consistent across World Nuclear News and DOE's packaging review. DOE's packaging reviewers independently recalculated criticality safety for the fuel's shipping package and agreed with the applicant. TRISO fuel's retention of fission products to about 1,600 C is stated in Valar's NSDA, and DOE says TRISO fuel is 'more resistant to neutron irradiation, corrosion, oxidation and high temperatures' than traditional reactor fuels. No active fault is mapped at the Ward 250 site, according to DOE's categorical exclusion and the Utah Geological Survey's fault map, and the same state map bears out Valar's no-fault claim for the Carbon parcel, as the Trust Lands memo relays it; the flood reasoning for Ward 250 is consistent across Valar's NSDA and DOE's categorical exclusion. The NOVA test was accurately described as operated by Los Alamos under NNSA oversight at zero power (orig-008). The 1 July electricity demonstration shows no sign of a commercial sale that would cross the EO 14301 line. The company's passive-cooling design is consistent with its safety documents, though the June 26 test is known only from Valar. Checked against Valar's own paper: its core-table arithmetic holds; its 100 m worker dispersion factor is at or above DOE's prescribed default; its 0.2 g earthquake value is close to the USGS design value for the site on soft rock (about 0.21 g); and its staffing of one senior operator and one operator per shift meets the NRC research-reactor benchmark.

In plain termsNot everything Valar says is contradicted by the record. The reactor really was approved by DOE and really did start up. It really was flown empty, and the fuel was approved to travel separately in a shipping package DOE checked for itself. DOE says the fuel type, TRISO, is 'more resistant to neutron irradiation, corrosion, oxidation and high temperatures' than traditional reactor fuels. Where the record supports the company, this file says so.
verified 2026-10-02: Re-checked in late September 2026 against DOE's 18 June 2026 release, World Nuclear News and DOE's packaging safety evaluation report. Holds. Revised before publication (late September 2026): added the NSDA values that check out (core table, 100 m factor, 0.2 g, staffing). Revised before publication (2026-09-30): reworded the detail; reworded the plain-language text; reworded the headline; removed the citation of Union of Concerned Scientists (advocacy publication); now cites U.S. Department of Energy, Office of Nuclear Energy instead; corrected the description of U.S. Department of Energy, Office of Nuclear Energy (quote).
analysisreported 'CAT scan' spent-fuel claim still on Valar's site; no supporting calculation or correction found there
2026-09 · safe-026 · Valar Atomics, Isaiah Taylor

Valar's April 2025 lawsuit post, still online in late September 2026, says its analysis indicates that holding spent fuel from its 100 kWt 'Ward One' test reactor (planned life under a month) for five minutes gives radiation exposure equal to a CAT scan. Valar's Ward 250 safety paper, the NSDA, credits reactor shielding that 'cannot be inadvertently defeated', analyzes fuel-handling accidents, and plans defueling into storage; DOE's categorical exclusion has the spent core leave in dry storage casks. No Valar correction or published calculation was found on Valar's website as of late September 2026. For scale: a CT scan is about 1 to 10 millisieverts (FDA), so five minutes would need 12 to 120 millisieverts an hour; the post gives no amount of fuel, cooling time, distance or shielding.

In plain termsUsed reactor fuel is radioactive; how much depends on the reactor's power, how long it ran and how long the fuel has cooled. Valar said holding used fuel from its planned Ward One test reactor for five minutes would be like one hospital CT scan. No calculation supporting it was found on its website, where the claim remains. For Ward 250, its own safety paper treats radiation shielding as a safety function, and DOE's review has the used fuel leave in dry storage casks.
verified 2026-10-02: Re-read Valar's 7 April 2025 post in late September 2026: the five-minute CAT-scan sentence is still on the page, with no correction or supporting calculation. Corrected in late September 2026: added the CT-scan dose-rate scale; removed a quoted phrase that was not Valar's wording. Corrected 30 Sept 2026: reworded the headline, detail and plain-language text to rest on government and company documents; a news citation was removed; now also cites the U.S. Energy Information Administration and the U.S. Department of Energy, Office of Nuclear Energy.
company claimconfirmed The $1B plan in Valar's words: fleets 'en masse', then thousands a year; no site, model, factory or date is named
2026-08-04 · plan-020 · Valar Atomics, U.S. Department of Energy, U.S. Nuclear Regulatory Commission · Series B equity, as announced by Valar: $1,000,000,000

Valar's Series B post (4 August 2026) says the money lets it move from demonstrating one integrated reactor to 'producing fleets of them en masse', with each reactor shortening the next until Valar produces 'tens, then hundreds, then thousands of reactors per year' in factories 'filled wall to wall' with small modular reactors, and that it will make its own fuel beside its reactors. It names no next reactor design or size, no factory site, no customer and no date. The concrete signs of the next step are elsewhere: a manager for 'one of Valar's first commercial projects' in Utah on the job board, a turbine program, the Carbon lease, a state tax-credit application projecting $1.3 billion of investment and 275 jobs in Emery County, and the 'Commercial Deployment by 2028' target in Valar's July 2025 Emery County slide deck (orig-045). DOE's July 2026 fact sheet, in its paragraph on Antares's Mark-0, says that demonstration set a baseline for 'subsequent reactors' to produce electricity 'in 2027 and the following years'; it gives no electricity date for Valar. Any reactor that sells power would need an NRC license under DOE's own terms; no NRC application or pre-application from Valar was found in public records as of late September 2026.

In plain termsValar raised a billion dollars on the promise of mass-producing reactors, eventually thousands a year. The announcement does not say what the next reactor is, where it will be built, or when. To sell power legally, a reactor needs a license from the Nuclear Regulatory Commission, and no application from Valar was found in public records as of late September 2026.
verified 2026-10-02: Checked in late September 2026: Series B post, DOE fact sheet and the July 2025 deck (1295975.pdf, 12 pages) re-read; quotes exact. Fixed: the fact sheet's 2027 sentence sits in its Antares paragraph and was described too broadly.
recordreported July 1, 2026 Orangeville event: Valar and NVIDIA announce they are exploring a 30 MW nuclear-powered data center
2026-07-01 · orig-042 · Valar Atomics, NVIDIA, Isaiah Taylor, Emy Lesofski, David Hinkins, Deseret News

Deseret News (Eva Terry, July 1, 2026) reported an event at Valar's Orangeville site with Taylor, an NVIDIA energy-policy director, Utah energy office director Emy Lesofski and State Sen. David Hinkins, where the companies said they are exploring a 30 megawatt data center fully powered by Valar's reactors. The article says Ward 250 was 'now generating 100 kilowatts of electricity'; that wording cannot match the 100 kW continuous thermal limit in Valar's safety agreement, which allows 250 kW only for up to an hour: a reactor limited to 100 kW of heat cannot deliver 100 kW of electricity, because turning heat into electricity always loses part of it. The figure is most likely the thermal rating reported as electric.

In plain termsOn July 1, 2026 at the Emery County site, Valar and NVIDIA said they are exploring a 30-megawatt data center run on Valar reactors. The newspaper's '100 kilowatts of electricity' cannot be right for a reactor limited to 100 kilowatts of heat in continuous running, because only part of the heat can become electricity.
verified 2026-10-02: Second check, late September 2026: Deseret re-read: event, speakers (an NVIDIA energy-policy director, Lesofski, Hinkins), 30 MW data-center study and '100 kilowatts of electricity' all present. The inference is now stated with its reason.
company claimconfirmed Valar calls itself 'very open and transparent', pointing to its photos and video; of its Ward 250 safety papers, two were found published, and the others, most listed for DOE review, were not found in public records
2026-06-28 · safe-040 · Valar Atomics

In its unlisted 'Ward 250 By the Numbers' page (28 June 2026), Valar says its beliefs have led it to be 'a very open and transparent company', that its reactor has been more photographed and filmed than any other in history, and that it is sharing raw data to be refined by internal and external peer review over the following weeks. The page still contains placeholders ('July XX', '[xxx]') and one chart, 'Reactor Power Ascension', which plots an unlabeled 'Q_Total' on a 0-100 scale and thermocouple readings of about 30-80 F against a 'sample index', with no power units, dates or time scale, so it cannot be used to check the power reached. Of the safety documents the NSDA and DOE records name for Ward 250, two were found published by Valar: the NSDA (marked 'Draft', though the Valar page that posts it says DOE has approved it) and the QA Program Description. Not found among Valar's published documents as of late September 2026: the PDSA, final DSA and Technical Safety Requirements, the Code of Record (document 100437), the startup and commissioning plan, the radiation protection program (DOE's categorical exclusion summarizes its dose limits), the transport QA program (document 100719, which DOE approved) and any emergency plan (the NSDA proposes on-site emergency response only, with no off-site planning, coordinated with local responders). The NSDA lists the safety analyses, operating limits, startup plan and safety programs as submittals to DOE; no requirement to post them publicly was found in the NSDA or in DOE's authorization standard, DOE-STD-1271. The Physical Security Plan and Material Control and Accountability Plan are security documents, which the NSDA calls separate controlled documents. County and state officials praised Valar's openness at the Trust Lands hearings.

In plain termsValar describes itself as unusually open, and it has published many photos and videos. The safety documents are a different matter: of the documents that define how the reactor is kept safe, we found two the public can read, and one is labeled a draft, though Valar says DOE approved it; the others were prepared for DOE's review. Some documents, like security plans, are normally kept private. The safety analysis and operating limits are not security plans; they can be requested from DOE under FOIA (safe-007).
verified 2026-10-02: Re-read 'By the Numbers' (single embedded image, the 'Reactor Power Ascension' chart, read from the image: Q_Total 0-100 with no units, thermocouples about 30-80 F, x-axis 'Sample index'), NSDA and QA Approval 0049 in late September 2026. Holds. Softened 'has published two' to 'two were found published': Valar's docs library page as posted lists five posts and no safety documents, so a complete inventory could not be made.

recordconfirmed DOE: Ward 250 completed zero-power fueled criticality in Emery County, second under the Reactor Pilot Program
2026-06-18 · orig-010 · Valar Atomics, U.S. Department of Energy, Chris Wright, Isaiah Taylor, Antares Nuclear

DOE's June 18, 2026 release says Ward 250 completed a zero-power fueled criticality demonstration at the Utah San Rafael Energy Lab in Emery County, the first DOE-authorized reactor built outside a national laboratory. DOE calls it the second of several reactors expected to go critical by the July 4 deadline in the May 2025 executive order; Antares Nuclear's Mark-0 at Idaho National Laboratory was first earlier that month. Energy Secretary Chris Wright and Isaiah Taylor are quoted; Taylor says the site was empty nine months earlier. DOE describes criticality as a sustained chain reaction that must precede power generation.

In plain termsDOE confirms that on June 18, 2026 Ward 250 in Emery County sustained a chain reaction at essentially zero power, the first step before a reactor makes heat. It was the second reactor to do this under DOE's pilot program. DOE says criticality must be achieved before a reactor can generate power; it shows a sustained chain reaction, not how the reactor performs at power, and it does not settle the separate questions about its safety documents (safe-007).

This shows Valar was seeking to test county land next to the state lab by early 2026: county minutes of 20 January 2026 call the parcel 'the property next to the Research Center', and the county later approved selling it to Valar (gov-022). Valar's Castle Country page says the commission backed the project unanimously. The commission's minutes of the same day record the support letter approved 3-0, subject to the county attorney's review and approval, and the MOU item as 'Tabled'.

World Nuclear News (Feb 18, 2026) reports the Ward 250 reactor, without its nuclear fuel, was loaded onto a C-17 at March Air Reserve Base in California on February 15, 2026 (Stars and Stripes reports three C-17s carried the modules) and flown to Hill Air Force Base, with Energy Secretary Chris Wright and Under Secretary Michael Duffey aboard, for later transfer to the Utah San Rafael Energy Lab. WNN, citing Reuters, says Wright stated fuel would move separately from the Nevada National Security Site. ExecutiveGov describes the same flight as a DOW-DOE partnership. This shows the reactor hardware was in Southern California before it moved to Utah; Valar's June 2026 draft says it was tested at its Hawthorne headquarters (orig-059).

recordconfirmed Project NOVA: Valar-built HALEU TRISO core reached zero-power criticality at LANL's NCERC in Nevada
2025-11-17 · orig-008 · Valar Atomics, Los Alamos National Laboratory, National Criticality Experiments Research Center, National Nuclear Security Administration, Nevada National Security Site

A joint Los Alamos National Laboratory and Valar announcement (posted on Valar's site, dated November 18, 2025) says the NOVA core reached zero-power ('cold') criticality at 11:45 a.m. PT on November 17, 2025, at LANL's National Criticality Experiments Research Center on the Nevada National Security Site, after approach-to-criticality work began November 12. Valar built the central core and supplied the TRISO fuel; LANL operated it on NCERC's Comet critical assembly and supplied the facility safety envelope, instruments, reflectors and analysis, under NNSA Nevada Field Office oversight. The core is graphite-moderated, HALEU TRISO-fueled, with boron-carbide control elements, and was configured to model the Ward 250 core. The release itself stresses there was no power production, grid connection or full-temperature operation. The claim of the first criticality by a venture-backed company is the company's. POWER magazine (June 2026) independently describes the same November 2025 campaign and notes it ran under NNSA oversight at LANL, not under the Reactor Pilot Program authorization.

In plain termsIn November 2025 a core built by Valar and loaded with its fuel reached a self-sustaining chain reaction inside a Los Alamos laboratory machine in Nevada, run by Los Alamos staff. 'Zero power' means the reaction made no useful heat or electricity; it tests the physics only.
verified 2026-10-02: Second check, late September 2026: release re-read: times, dates, roles (Valar core and fuel; LANL assembly, safety envelope, reflectors, instruments, analysis), NNSA Nevada Field Office oversight and the no-power caveat all match.

analysisconfirmed Ward 250's safety papers lean on Ward Zero tests and reuse its hardware; no Ward Zero test data was found in public records as of late September 2026
2025-10 · orig-059 · Valar Atomics, U.S. Department of Energy, Ward Zero, Ward 250

Valar's NSDA (October 2025) says Ward 250 directly uses hardware that has undergone full-scale testing, that design work focuses on nuclear-specific modifications to the proven WardZero configuration, and it credits Ward Zero testing for key safety points: natural circulation during a loss of coolant flow, and the capacity of the Reactor Cavity Cooling System. It also asks DOE to accept the final safety analysis at 90% design completion because the WardZero program has completed design, installation and testing of major safety-significant systems. Valar's QA Program Description, which Valar's October 13, 2025 post says DOE approved, has a section on using existing WardZero hardware: Ward Zero components may go into Ward 250 if they stay traceable and are evaluated, and Ward Zero operating data may count as design verification by comparison to 'similar proven systems'. Ward Zero was completed in February 2025, before that QA program was approved. Valar's June 2026 draft says the reactor underwent non-nuclear testing at its Hawthorne headquarters above 750 C and 6 MPa before shipment. No Ward Zero test report, data set or DOE review of it was found in public records as of late September 2026, and the page titled 'Ward Zero Whitepaper' holds no Ward Zero data (orig-058). Whether DOE examined the Ward Zero data would be shown by the PDSA and DSA, of which no public copy was found (safe-007).

In plain termsWard 250 was not built from scratch in Utah. By Valar's own safety papers it reuses parts of Ward Zero, the electric-heated prototype tested in California, and Ward Zero's tests are offered as proof that key safety features work, such as the reactor cooling itself by natural air flow. Some of that hardware was built before the quality program was approved by DOE, as Valar says it was; the program allows that if the parts are traced and checked. No Ward Zero test results were found in public records, so the public cannot check the evidence this part of the safety case rests on.

recordconfirmed Who approves Ward 250: DOE alone. Its safety agreement says no move to an NRC license is planned
2025-10 · safe-001 · Valar Atomics, U.S. Department of Energy, Nuclear Regulatory Commission

Valar's Nuclear Safety Design Agreement (NSDA, document 100403 rev 02, October 2025) says Ward 250 is a contractor-owned, contractor-operated facility 'under DOE jurisdiction', authorized under the federal nuclear safety rule 10 CFR 830, with DOE-STD-1271-2025 as its primary authorization standard, and that no transition to NRC licensing is planned or intended. DOE's NEPA determination of 22 April 2026 says the same: the facility 'will operate under U.S. Department of Energy (DOE) authorization'. The legal basis is Executive Order 14301 (23 May 2025): section 3 finds that advanced reactors under enough DOE control that are not built 'to produce commercial electric power' fall within DOE's jurisdiction rather than the NRC's, and section 5 orders a pilot program outside the national laboratories under 42 U.S.C. 2140, approving at least three reactors 'with the goal of achieving criticality' in each by 4 July 2026. DOE-STD-1271 itself exempts anything the NRC regulates. The text of DOE-STD-1271 contains no public-hearing or public-comment step (searched for 'hearing', 'public comment', 'comment period'); its foreword only invites emailed suggestions for improving the standard itself.

In plain termsTwo federal agencies can approve a reactor. The Nuclear Regulatory Commission (NRC) is the independent safety regulator for commercial reactors, and its licensing includes published notices and a chance for the public to ask for a hearing. The Department of Energy (DOE) can instead approve test reactors it controls. Ward 250 took the DOE route, so the agency that sponsors the pilot program is also the one that judges its safety, and the DOE rulebook used has no step where the public comments or asks for a hearing. This is the route the 2025 executive order set up; it also means far less of the review happens in public.

company claimconfirmed Ward 250 groundbreaking: Valar's page says 17 Sep 2025; state records put the ceremony on 11 Sep 2025
2025-09-11 · orig-007 · Valar Atomics, Ward 250, Utah San Rafael Energy Lab

Valar's Ward 250 page lists 'Ward 250 Groundbreaking' on 09.17.2025, and its Castle Country page lists a local news item from September 2025 about breaking ground at the Utah San Rafael Energy Lab. DOE's June 18, 2026 release quotes Taylor saying the site was empty nine months before criticality, consistent with a September 2025 start. State records settle the ceremony date: the Office of Energy Development's slide update to the Legislature's interim committee (15 October 2025) says Valar 'held groundbreaking' on September 11, 2025, Emery County's 2 September 2025 minutes say ground would be broken 'on September 11', and the county economic board's minutes schedule it for that Thursday (gov-021). 17 September 2025 is the day the joint state-Valar release was published, which is the date Valar's page shows.

In plain termsConstruction at the Emery County lab began in September 2025, about nine months before the reactor first went critical in June 2026. State records put the groundbreaking ceremony on 11 September 2025; Valar's page shows 17 September, the day the announcement was published.
verified 2026-10-02: Second check, late September 2026: Ward 250 page date and DOE's quote of Taylor ('Nine months ago...') re-read; consistent. Further check, late September 2026: the event date had been taken from the company's page (17 Sept); state and county records read in late September 2026 (among them gov-021) put the ceremony on 11 Sept 2025, so the date field and headline now carry the recorded event date, with Valar's date kept as its claim.
company claimconfirmed Valar announces DOE selection to reach criticality by July 4, 2026 under Executive Order 14301
2025-08-12 · orig-006 · Valar Atomics, U.S. Department of Energy, Isaiah Taylor, Spencer Cox, Chris Wright

In a post dated August 12, 2025, signed by Isaiah Taylor, Valar said DOE had selected it to achieve criticality on American soil by July 4, 2026, pursuant to Executive Order 14301. The post thanks President Trump and Energy Secretary Wright, and Governor Cox and his administration for their partnership, names the test site as the San Rafael Energy Research Center in Emery County, and says testing there can proceed without multi-year licensing delays under the new framework. It describes the test reactor as a TRISO-fueled high-temperature proof-of-concept and claims operating temperatures above 750 C. The post frames the effort as a 'second Manhattan Project'.

In plain termsIn August 2025 the Energy Department picked Valar as one of the companies allowed to try to start a test reactor by July 4, 2026, under a presidential order. Being picked meant permission to try under DOE's oversight, at the company's own cost, not federal money to build.

company claimconfirmed July 2025 Emery County town hall: Valar pitched a 12-month test, ~40 jobs, 'commercial development by 2028'
2025-07-08 · orig-045 · Valar Atomics, Emery County Commission, Utah San Rafael Energy Lab, Jaron Wallace, Jeremy Pearson

ETV News (Julie Johansen, July 9, 2025) reported the Emery County Commission's July 8, 2025 town hall in Castle Dale, requested by Valar after an MOU was signed and before its contract with the state lab was final. As reported, Valar said the company was about two years old, had a non-fueled test reactor near Los Angeles, aimed for July 4, 2026 (the nation's 250th birthday, hence 'Ward 250') with commercial development by 2028, expected about 40 employees for roughly 12 months of testing with local contractors for construction, and chose Utah because Carbon and Emery counties are the state's energy hub. A Valar slide deck posted on the state-run Utah Public Notice Website (file created July 8, 2025, server date 9 July 2025; 11 of its 12 pages are marked 'CONFIDENTIAL. DO NOT DISTRIBUTE.', yet the file is publicly posted; the public body and notice it is attached to were not identified) says the same: under 250 kW, 30 effective full-power days over 12 months in a temporary facility, commercial deployment by 2028.

In plain termsAt a July 2025 town hall Valar told Emery County residents about a small 12-month test with about 40 jobs, and a goal of commercial reactors by 2028. By 2026 the company was planning far larger sites (mine-019).

company claimreported April 2025: Valar joins states' suit against the NRC over small-reactor licensing; names 'Ward One'
2025-04-07 · orig-016 · Valar Atomics, U.S. Nuclear Regulatory Commission, Last Energy, Deep Fission, State of Utah, State of Texas

In a post dated April 7, 2025, Isaiah Taylor announced Valar was joining Texas, Utah, Louisiana, Florida and Arizona (in the complaint, the Arizona State Legislature), and the reactor companies Last Energy and Deep Fission, in a lawsuit against the Nuclear Regulatory Commission. The argument, as Valar summarizes it, is that the Atomic Energy Act of 1954 narrowed federal licensing to reactors significant to defense or public safety, and that a 1956 rule wrongly swept in all reactors. The post says Valar's planned 'Ward One' test reactor is named in the suit. Litigation status and outcome are tracked in safe-028.

In plain termsIn April 2025 Valar joined Texas, Utah and other states in suing the federal nuclear regulator (the NRC), arguing small reactors should not need its license at all. Utah, which later hosted Valar's reactor, is one of the states in that suit.

company claimreported Design lineage: 'Ward One' was a 100 kWt TRISO HTGR planned for under a month of operation
2025-04-07 · orig-017 · Valar Atomics, Isaiah Taylor, Ward One

The April 2025 lawsuit post describes Ward One as a 100 kWt high-temperature gas reactor using TRISO fuel, named, the founder writes, after a Manhattan Project-era relative of his, with a planned operating life of less than a month. It says the design relies on strong negative thermal reactivity feedback and low power density for fully passive decay-heat removal, and claims that holding its spent fuel for five minutes would give the same radiation exposure as a CAT (CT) scan. The later Ward 250 carries the same 100 kWt figure, which suggests Ward 250 grew out of the Ward One concept, though no source read says so directly. Ward One itself was still unbuilt in the Philippines as of April 2026. For scale: a CT scan is about 1 to 10 millisieverts (FDA), so five minutes would need 12 to 120 millisieverts an hour; the post gives no amount of fuel, cooling time, distance or shielding.

In plain termsWard One was Valar's first planned uranium reactor: very small (100 kilowatts of heat) and meant to run for less than a month. It was to be built in the Philippines; as of April 2026 it had not been built there.

TechCrunch (Mike Butcher, February 20, 2025) reported Valar had raised a $19 million seed round led by Riot Ventures, with AlleyCorp, Initialized Capital, Day One Ventures and Steel Atlas, to develop its first test reactor. It reported an initial contract with the Philippine Nuclear Research Institute to build a reactor in that country, and quoted the company saying its thermal test unit took about 10 months to design and build. The article described the technology as helium-cooled and reaching up to 900 C. It did not say where the company is based. Initialized Capital, an investor, gave the round as $18 million.

In plain termsValar came out in public in February 2025 with $18-19 million from investors (published figures differ) and a deal to build a reactor in the Philippines.

recordconfirmed Valar's 'Ward Zero Whitepaper' page holds no Ward Zero data: its text is a 2019 essay by another author, word for word
2024-12-01 · orig-058 · Valar Atomics, Cairo Review of Global Affairs, Ward Zero

Valar's website has a page titled 'Ward Zero Whitepaper', subtitled as a detailed account of how its first prototype reactor works, dated December 1, 2024 and credited to Isaiah Taylor, Kip Mock and Mark Mitchell. It is not listed in the library but loads at its public URL (read in late September 2026), and its entry is carried in the data that the Ward 250 page loads. Its body says nothing about Ward Zero. Every one of its body sentences matches, word for word, 'A Nuclear Curse and a Nuclear Blessing', an essay on Russian and Chinese reactor exports to the Middle East by Selim Sazak in the Fall 2019 issue of the Cairo Review of Global Affairs; the page names no source and still says the UAE's Barakah plant is expected to be fully operational by 2020. Archived copies show the same text on the page in April 2025, beside three other unlisted posts whose bodies read only 'Lorem ipsum', and again in October 2025, by when the placeholder posts were gone. That fits leftover placeholder text rather than a finished paper (Valar has not said); the record does not show why it was used or why it remains. Either way, the one document Valar titled as a technical account of Ward Zero contains none (orig-059).

In plain termsValar's safety documents lean on tests of its non-nuclear prototype, Ward Zero. The only page on its website titled as a Ward Zero 'whitepaper' contains no Ward Zero information; its text matches, word for word, a 2019 magazine essay by another author about Middle East politics. The page is not listed in the site's menus and may be leftover placeholder text (Valar has not said), but it means no technical paper on Ward Zero was found in public records (as of late September 2026).

A Deseret News profile (Eva Terry, March 17, 2026) says Taylor founded Valar Atomics on the Fourth of July in 2023 and calls it an El Segundo-based startup; it names Jess Housekeeper as Valar's director of Utah operations and says the reactor's stackable concrete shielding blocks are made in Salt Lake City. This agrees with Contrary Research's July 2023 date and ANS's El Segundo headquarters; other records, including an unfinished June 2026 page on Valar's site and Valar's March 2026 trademark filing, give a Hawthorne, California address. The legal entity is confirmed elsewhere (a Delaware corporation), but no state record showing the formation date was found in the records read.
