Research Brief

What is new: the latest research brief, the top conflicts, facts first seen in the last few days, and new items from public sources.

Claims vs Record: 10 open entries

documented conflict Ward 250's fuel: Valar's safety agreement lists 4.95% uranium; its Los Alamos release and DOE's shipping review say HALEU
documented conflict 'Not trying to keep anything from anyone', said the lab director; the state's MOU with Valar said it and related information were confidential, except as required by law; the energy office uses similar terms with some other nuclear companies
claim not supported Spent fuel for five minutes like a CAT scan: no supporting calculation or correction found on Valar's site as of late September 2026
unresolved How much fuel is in the core: 76 elements on paper, 24 cleared to ship, and 'very lightly loaded' in Valar's words
unresolved Worst-case dose built on 30 full-power days (3 megawatt-days); the same paper's burnup limit reads 30 megawatt-days
unresolved Outlet temperature: 650°C is the limit, and Valar's public summary says 650°C; the same draft lists 750°C 'under normal operations' as a goal
unresolved Emergency planning: Valar asked for on-site only, cited state-DOE agreements and drills; none found in public records
unresolved DOE confirms Ward 250 is authorized and that a federal readiness review took place, but each approval's date is known from Valar's word; the paper it said DOE approved was marked 'In Review'

Records added by the latest research, each checked against its sources.

safe-010 DOE shipping review: fuel for Ward 250 is HALEU (under 20%), not the 4.95% its safety agreement lists
safe-026 'CAT scan' spent-fuel claim still on Valar's site; no supporting calculation or correction found there
csite-032 The state's first public notice of the lease (RDCC, April 20, 2026) called it an industrial and power project; no nuclear, no name
mine-013 Carbon commissioners signed a June 29 support letter; no Carbon County agenda from May to mid-Sept shows it or the site
safe-014 Valar's draft accident math puts the nearest public access 400 m away; the host lab is 20.6 acres, too small to hold a 400 m radius
safe-016 Emergency planning: Valar asked to plan for on-site emergencies only; no public record shows DOE agreed
safe-007 What DOE has made public about Ward 250 safety, and what was not found: no DSA, TSRs, SER or startup approval, though DOE says its teams reviewed Ward 250's readiness before startup
safe-009 The accident analysis assumed 3 megawatt-days of fuel use; the same document's limit allows 30, ten times more
gov-011 The state's earliest agreement with Valar found in public records (May 16, 2025) made it and 'related information' confidential, except as required by law, and barred publicity without consent; the energy office uses similar terms with some other nuclear companies
csite-024 Utah approved up to $106.7M in tax credits for Valar in July 2026 (Emery County); like all 13 tax-credit applicants the board took up from April to September 2026, it was not named on the public agenda
safe-039 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

New facts (first seen in the last 3 days): 6

newrecordconfirmed Carbon County's planners added a Valar Atomics presentation to their October 6 agenda on October 2

2026-10-02 · loc-037 · Carbon County Planning Commission, Valar Atomics, Utah Public Notice Website

The Carbon County Planning Commission's notice for its regular meeting on Tuesday, October 6, 2026 at 4:30 p.m. in the Commission Chambers, 751 East 100 North, Price, was edited on October 2, 2026 at 8:49 a.m. The amended agenda adds item 6, 'Presentation to the Planning Commission from Valar Atomics regarding their proposed project in Carbon County'. The agenda first posted with the notice (a one-page PDF created September 23, 2026, still on the state site as file 1492435) had seven items and no Valar item, and the notice read on September 29 matched it. Neither version lists a public comment item, and the notice says neither electronic nor telephone participation is available. The edit also removed the agenda PDF from the notice. Item 5, the conditional use permit for a technology park east of Wellington for Altigen JS, LLC and Duct Tape, LLC, is unchanged and separate; no record read links that project to Valar.

In plain termsValar is now on the agenda for the county planners' meeting on Tuesday, October 6, at 4:30 p.m. in Price: the agenda was changed on October 2 to add a presentation from Valar about its proposed project in Carbon County. The agenda lists no public comment item, and the meeting is in person only.

newrecordconfirmed Aug 12, 2026: the state energy research board's agenda set its meeting at the San Rafael lab, with a public-comment item and a board tour of the lab and Valar listed

2026-08-12 · gov-042 · Utah Energy Research Board, Utah San Rafael Energy Lab, Valar Atomics

The Utah Energy Research Board's amended agenda for 12 August 2026 (file dated 6 August 2026) places the meeting at the Utah San Rafael Energy Lab, 800 North Coal Haul Rd, Orangeville, 10 to 11 a.m., with a video and phone option. It lists a lab update (item 7), 'OTHER BUSINESS: Open to public comment' (item 13), and, after the meeting, a 'Tour of Utah San Rafael Energy Lab and Valar Atomics for Board Members'. The agenda has no item on a Valar project and does not say whether the public could join the tour. The board's first meeting, on 13 August 2025 in Salt Lake City, at which it approved 'the Valar Project', also closed with a public comment period, in which attendees, per the minutes, expressed appreciation for the board's formation (gov-013). The 12 August 2026 minutes were not read.

In plain termsThe state board that approves projects at the San Rafael lab set its August 2026 meeting at the lab itself in Emery County, with time on the agenda for public comment, and listed a tour of the lab and Valar Atomics for its members afterwards. The agenda does not say whether the public could join the tour, and the meeting's minutes were not read. The board's 2025 meeting that approved Valar's project also ended with public comment.

newofficial statementconfirmed June 17, 2026 minutes: Carbon commissioners called the rate change a state-mandated adjustment to keep taxing entities whole, not a county tax increase

2026-06-17 · ptax-012 · Carbon County Commission, Larry Jensen

Final minutes of the Carbon County Commission meeting of 17 June 2026, item 7 on certified tax rates (PDF pp.2-3, read from the scanned pages). After recording Commissioner Jensen's explanation that centrally assessed values fell $48 million, primarily due to a gas field sale, 'which shifted the tax burden slightly', the minutes state that the commissioners repeatedly stressed this was 'a state-mandated adjustment to balance the budget and keep taxing entities whole', not a county tax increase. The three rates were then approved (PDF p.3). This is the minutes' summary of the discussion, not a transcript. Under Utah's truth-in-taxation law, a certified tax rate is the rate that gives a taxing entity the same property tax revenue it budgeted for the prior year. The minutes do not say which taxpayers the shift fell on.

In plain termsAt their 17 June 2026 meeting, the commissioners stressed that the certified rates were an adjustment required by state rules to keep the county's and other taxing bodies' money the same, not a county tax increase. The minutes say the drop in industry value shifted the tax burden slightly, but do not say onto whom.

verified 2026-10-02: Re-read the scanned pages of the 17 June 2026 final minutes, item 7 (PDF pp.2-3): the full sentence quoted in the detail and both short quotes match word for word on PDF p.3 (the clause 'which shifted the tax burden slightly' starts at the foot of p.2), and the rates were approved after that sentence. The minutes do not say who bears the shift.

newrecordconfirmed March 31, 2026: the Utah Energy Council's agenda put a Valar update at the San Rafael lab just before a public-comment item

2026-03-31 · gov-041 · Utah Energy Council, Utah Office of Energy Development, Valar Atomics, Utah San Rafael Energy Lab

The Utah Energy Council's agenda for its 31 March 2026 meeting (virtual, with an anchor location at the Cannon DHHS Building in Salt Lake City; posted on the Utah Public Notice Website, file dated 30 March 2026) lists item 7, 'Valar Atomics at San Rafael Lab Update', and item 8, 'Public comment', two minutes per speaker, which the agenda describes as 'time set aside for citizens to express their views' and says no immediate action can be taken on matters raised. Item 9 is a closed strategy session on the purchase, exchange or lease of real property under H.B. 70 (2025), which names no property (csite-031). The minutes of this meeting were not read, so what was said in the update or in public comment is not known. It is one of several noticed state meetings at which Valar's Emery work came up with a public-comment item on the same agenda (gov-040, gov-042).

In plain termsIn March 2026 the state's Energy Council had a Valar update on its posted agenda, followed directly by time for the public to speak. The agenda shows the chance to comment existed; the record read does not show what was said.

newrecordconfirmed The 'CONFIDENTIAL' marking is on a Valar deck posted publicly on the state's notice website; the Legislature's June 2025 Valar item used state slides without it

2025-07-08 · dir-038 · Valar Atomics, Utah Public Notice Website, Utah State Legislature, Utah Office of Energy Development

Valar's 12-page deck 'Valar Atomics + SRERC in Emery County' (PDF created 8 July 2025; server date 9 July 2025) is posted on the state-run Utah Public Notice Website as file 1295975, and 11 of its 12 pages carry the line 'CONFIDENTIAL. DO NOT DISTRIBUTE.'; the public body that posted it and the notice it is attached to were not found in the records searched (as of 1 October 2026). Its content (under 250 kW, 30 effective full-power days in 12 months in a temporary facility, commercial deployment by 2028) matches Valar's 8 July 2025 Emery County town hall as reported (orig-045) on the 12-month test and the 2028 commercial goal; the report does not give the power level or full-power days, or call the facility temporary. The Legislature's record of its 18 June 2025 committee meeting lists, for the Valar item, only OED's four-page 'Nuclear Update' slides, whose text carries no such marking (gov-040); Valar's own 17-slide deck filed with the same committee in May 2026 carries none either (gov-019). The marking shows how Valar labeled one deck. The deck itself is public, and the marking on its own does not show that any meeting or decision was confidential.

In plain termsOne Valar slide deck from July 2025 is stamped 'CONFIDENTIAL. DO NOT DISTRIBUTE.' on most pages, yet it is posted on the state's public notice website for anyone to download. The stamp shows how Valar labeled its slides; it does not show that any meeting or decision was closed to the public. The only slides on the Legislature's record for the June 2025 briefing were the state energy office's own, with no such stamp.

newrecordconfirmed June 18, 2025: legislators heard a noticed agenda item, 'Valar Atomics Nuclear Test Reactor', then took public comment on nuclear

2025-06-18 · gov-040 · Utah State Legislature, Public Utilities, Energy, and Technology Interim Committee, Utah Office of Energy Development, Utah San Rafael Energy Lab, Valar Atomics, Emy Lesofski, Jaron Wallace

The Legislature's Public Utilities, Energy, and Technology Interim Committee met on 18 June 2025 at the State Capitol. Its agenda (file dated 13 June 2025) lists item 3, 'Valar Atomics Nuclear Test Reactor', 9:00 to 9:30 a.m.: Valar had 'partnered with the San Rafael Energy Research Center' to have 'a new nuclear test reactor running by 2026', and the committee would hear about the plan from the Office of Energy Development and the research center. Per the approved minutes, OED Director Emy Lesofski and lab director Jaron Wallace 'gave an update on companies partnering' with the lab, 'including Valar Atomics and NuCube'. The Legislature's meeting record lists, for item 3, only OED's four-page slides, 'Nuclear Update', which give 'Valar MOU signed May 16, 2025'; no presentation filed by Valar is listed for this meeting, and OED's slides carry no confidentiality marking in their text. After the committee voted on a draft nuclear-manufacturing resolution, the chair 'opened the meeting to public comment on the nuclear discussion': four members of the public spoke, some for more nuclear power and others urging caution and asking that communities be included in decisions. The meeting record also lists the meeting notice, the approved minutes and an audio/video recording. The meeting came 33 days after the OED-Valar MOU (gov-011) and the day after Emery County's public hearing on nuclear industries (gov-020). It was an informational update: the committee took no action on Valar, and it was not a hearing on the reactor's safety.

In plain termsA year before Ward 250 started up, state legislators had a posted agenda item called 'Valar Atomics Nuclear Test Reactor', describing a test reactor planned at the Emery County lab by 2026. State energy officials briefed the committee, and later in the same meeting members of the public spoke on the nuclear discussion, some supporting more nuclear power and others urging caution. It was a briefing, not a hearing on whether the reactor is safe, but it shows the plan itself was discussed in public by June 2025.
