Cycle on Jun 1, 2026

I will begin by listing the open research threads for this topic to see what specific questions or investigations the user has prioritized.

I will call the `market_view` tool to retrieve current market data for key nuclear utility and reactor developers mentioned in the brief: Constellation Energy (CEG), Vistra (VST), NuScale Power (SMR), and Oklo (OKLO). This will provide the latest financial metrics, stock performance, and market context.

I will pull the market views for Vistra (VST), NuScale Power (SMR), Oklo (OKLO), and Nano Nuclear Energy (NNE) to see how those stocks and their financials are trending. Let's start with VST.

I will now pull the market views for NuScale Power (SMR), Oklo (OKLO), and Nano Nuclear Energy (NNE) to see how the SMR space is performing. Let's start with SMR.

Let's also look at Oklo (OKLO) and Nano Nuclear Energy (NNE). I will call `market_view` for OKLO first.

Let's pull the market view for Nano Nuclear Energy (NNE).

Excellent, now let's pull market views for the major uranium suppliers: Cameco (CCJ) and Kazatomprom (if listed, or via web/sector). Let's see if CCJ is available.

Let's check `market_view` for Southern Company (SO) to complete the key utility trackers listed in the brief.

Let's look at the threads we have. One is: "Monitor advanced negotiations and fuel agreements under the DOE Surplus Plutonium Utilization Program" The other is: "Track NRC safety and environmental review progress for UIUC KRONOS MMR microreactor" Let's do some web searching on these two. First, let's search for "DOE Surplus Plutonium Utilization Program" and the selected companies (Oklo, Flibe, Exodys, Shine, Standard Nuclear). Let's see what news came out in late May or June 2026. This is highly relevant because Oklo was selected for advanced negotiations. Let's run a search.

This is incredibly interesting. Let's look at the NYT article and the ANS (American Nuclear Society) or S&P Global articles. Let's fetch the NYT article or the ANS article to see the details of the negotiations. Let's fetch `https://www.nytimes.com/2026/05/26/climate/plutonium-nuclear-weapons-fuel.html` and `https://www.ans.org/news/article-8075/doe-selects-five-companies-to-negotiate-receipt-of-surplus-us-plutonium/`. Let's start with NYT first.

Ah, the NYT is not supported. Let's fetch the ANS article instead: `https://www.ans.org/news/article-8075/doe-selects-five-companies-to-negotiate-receipt-of-surplus-us-plutonium/`. Let's perform this fetch.

This is extremely detailed and provides excellent quotes and background on the DOE Surplus Plutonium Utilization Program. Let's see: - Program was established last year (2025) with a request for applications for up to 20 metric tons of DOE-owned plutonium (4.4 MT metal and 15.3 MT oxides). - Follows Trump's Executive Order 14302, "Reinvigorating the Nuclear Base", which halted the Biden-era "dilute and dispose program" at the Waste Isolation Pilot Plant. - Five companies selected: Oklo, Flibe Energy, Exodys Energy, Shine Technologies, and Standard Nuclear. - Oklo is partnering with European company Newcleo (which is developing a $1.68 billion advanced fuel center in Oak Ridge, Tenn.). - Flibe Energy is developing lithium fluoride thorium reactor technology. - There is political pushback: Sen. Edward Markey (D., Mass.) and Reps. John Garamendi and Donald Beyer sent a letter opposing it. Let's do a search on the other thread: "Track NRC safety and environmental review progress for UIUC KRONOS MMR microreactor". The UIUC KRONOS MMR is associated with Nano Nuclear Energy (NNE) and the University of Illinois Urbana-Champaign. Let's search for "University of Illinois" "Nano Nuclear" "KRONOS" OR "MMR" OR "NRC" 2026.

Let's fetch the MSN/Earnings Call article: `https://www.msn.com/en-us/money/companies/nano-nuclear-anticipates-mid-to-late-2027-initial-construction-at-university-of-illinois-following-nrc-acceptance-process/ar-AA23ffSM` or the Federal Register document: `https://www.federalregister.gov/documents/2026/05/26/2026-10419/university-of-illinois-urbana-champaign-construction-permit-application`. Let's also look at the Stock Titan or Newsfile Corp release on the acquisition of STS and the NRC acceptance. Let's fetch the Newsfile release: `https://www.newsfilecorp.com/release/298833/NANO-Nuclear-Acquires-Secured-Transportation-Services-LLC-Establishing-a-Fully-Integrated-Nuclear-Fuel-Logistics-and-Transportation-Platform-and-Joining-a-Select-Group-of-RevenueGenerating-Microreactor-Developers`. And let's fetch the NucNet article: `https://www.nucnet.org/news/us-nrc-accepts-application-for-advanced-microreactor-at-illinois-university-5-5-2026`. Let's perform these fetches.

Awesome. Let's do a search on the NRC acceptance of the construction permit application for the UIUC KRONOS microreactor. Let's see what the specific date was, what the timeline is, and details about the review. Let's search for "University of Illinois Urbana-Champaign" "KRONOS" "construction permit" "NRC" May 2026.

Let's fetch the NucNet article: `https://www.nucnet.org/news/us-nrc-accepts-application-for-advanced-microreactor-at-illinois-university-5-5-2026`. And let's fetch the FinanzNachrichten article (which seems to have the PR text of the NRC acceptance of the construction permit): `https://www.finanznachrichten.de/nachrichten-2026-05/68549060-nano-nuclear-energy-inc-nano-nuclear-s-kronos-mmr-and-the-university-of-illinois-urbana-champaign-advance-to-next-regulatory-milestone-as-u-s-nrc-f-296.htm`. Let's perform these fetches.

Let's fetch the other URL: `https://www.finanznachrichten.de/nachrichten-2026-05/68549060-nano-nuclear-energy-inc-nano-nuclear-s-kronos-mmr-and-the-university-of-illinois-urbana-champaign-advance-to-next-regulatory-milestone-as-u-s-nrc-f-296.htm`. Let's run this fetch.

This is fantastic. We have two solid, high-detail findings that directly address the user's threads and update prior notes. Let's see what prior notes we have: 1. `doe-surplus-plutonium-program-2026`: "DOE Pivots to Fueling Advanced Reactors with Weapons-Grade Plutonium" We can update this note to include the definitive news of the five selected companies (Oklo, Flibe Energy, Exodys Energy, Shine Technologies, and Standard Nuclear) and the specific details of the advanced negotiations, Oklo's partnership with Newcleo, Flibe's technology, and the political pushback from Markey, Garamendi, and Beyer. 2. `nano-nuclear-energy-nrc-milestone-2026`: "Nano Nuclear Energy Microreactor Design Reaches Key Regulatory Milestone with NRC" We can update this note to include the formal acceptance of the Construction Permit Application (CPA) on May 20, 2026, for the University of Illinois Urbana-Champaign (U. of I.) KRONOS MMR deployment. The CPA was submitted on March 31, 2026. The estimated timeline is that the NRC's formal review will be completed in 2027, with construction starting in the second half of 2027. We can also mention NNE's acquisition of Secured Transportation Services LLC (STS) for up to $13 million on May 22, 2026, which makes NNE vertically integrated and adds revenue-generating logistics operations ($7.1M revenue, $1.3M net income in 2025). Let's check if there are other nuclear-related news developments in public markets, utilities, or uranium contract pricing. Let's do a general search for "uranium spot price" or "uranium contract prices" 2026 or "nuclear power purchase agreement" 2026. Let's run a search.

Let's fetch the MSN article about Denison Mines' uranium contracts: `https://www.msn.com/en-us/money/topstocks/can-dnns-growing-uranium-contracts-drive-future-growth/ar-AA24cVxt`. And let's fetch the Barchart article on Uranium Energy's production timeline: `https://www.barchart.com/story/news/2225066/uranium-energy-s-production-timeline-keeps-shifting-while-the-market-pretends-not-to-notice`. Let's perform these fetches.

This is an incredibly rich source of data on uranium long-term contract pricing and market trends in 2026. Let's see: - Denison Mines Corp. (DNN) is securing long-term uranium contracts well ahead of its flagship Wheeler River (Phoenix) project’s mid-2028 targeted start. - In Q1 2026, Denison announced agreements to sell 550,000 lbs of uranium for delivery between Q2 2026 and Q1 2027 at an average price of nearly $99 per pound. - As of Q1 2026, the company has 1.35 million pounds committed for delivery between Q2 2026 and Q2 2027, with 0.95 million pounds fixed at an average price of $92.05 per pound. The remaining 400,000 lbs are market-related. - Denison has secured firm sales commitments for nearly 8 million pounds of uranium from physical holdings and expected future production, and is negotiating another 8 million pounds. - Customer base includes major North American utilities operating over 50 reactors. - This represents a broader structural change in the nuclear fuel market, with utilities pursuing long-term contracting strategies to secure supply. Let's fetch the Barchart article on Uranium Energy Corp (UEC) to see its production timeline shift: `https://www.barchart.com/story/news/2225066/uranium-energy-s-production-timeline-keeps-shifting-while-the-market-pretends-not-to-notice`. Let's perform this fetch.

This is very interesting. The Barchart article provides a great view of Uranium Energy Corp (UEC) as of June 1, 2026. Wait, let's look at what is happening in the uranium markets. We have: - Denison Mines Corp (DNN) locking in long-term contracts at high prices ($92 to $99 per pound) well ahead of production starting in mid-2028. - Uranium Energy Corp (UEC) reporting earnings on June 1, 2026, with an expected quarterly GAAP EPS loss of $-0.05, while navigating an operational ramp-up and a shifting production timeline that "keeps shifting while the market pretends not to notice." UEC is trading at $13.77. - Cameco Corporation (CCJ) reporting strong Q1 2026 results with EPS of $0.47 (vs $0.34 expected) on $845.4 million in revenue, supported by its Key Lake mill and McArthur River mine returning to full production following a labor dispute. CCJ has a market cap of $49.08B. Let's organize the findings: 1. **DOE Surplus Plutonium Program (slug: `doe-surplus-plutonium-program-2026`)**: We will update this finding to detail the advanced negotiations opened in late May 2026 between the DOE and the five selected companies: Oklo, Flibe Energy, Exodys Energy, Shine Technologies, and Standard Nuclear. We'll include details about Oklo's partnership with Newcleo and Flibe's study of spent fuel recycling, plus political opposition from congressional Democrats (Sen. Edward Markey, Reps. John Garamendi and Donald Beyer). 2. **Nano Nuclear Regulatory and Corporate Progress (slug: `nano-nuclear-energy-nrc-milestone-2026`)**: We will update this finding to detail the formal acceptance of the Construction Permit Application (CPA) on May 20, 2026, for the University of Illinois Urbana-Champaign KRONOS MMR deployment. We'll also detail Nano Nuclear's $13 million acquisition of Secured Transportation Services LLC (STS) on May 22, 2026, adding a critical nuclear transport logistics arm and making NNE a vertically integrated, revenue-generating company ($7.1M revenue, $1.3M net income in 2025). 3. **Uranium Contract Prices and Producer Trajectories (slug: `uranium-pricing-supply-constraints-2026`)**: We will update this finding to cover the 2026 contracting boom. We'll highlight Denison Mines (DNN) securing contracts for 1.35 million lbs of uranium for delivery between Q2 2026 and Q2 2027 at high prices ($92.05 to $99.00 per pound), well ahead of its mid-2028 Phoenix project start. We will also include Cameco's (CCJ) Q1 2026 earnings beat ($0.47 EPS vs $0.34 expected) and full restart of Key Lake/McArthur River, and contrast it with Uranium Energy Corp's (UEC) shifting production timelines and expected Q4 2026 loss of $-0.05 per share. Let's double check if there are any other threads we can resolve. We have: - `019e84fb-3fbe-7cd1-a749-e2fcb9753199`: "Monitor advanced negotiations and fuel agreements under the DOE Surplus Plutonium Utilization Program" -> Resolved by updating `doe-surplus-plutonium-program-2026`. - `019e84fb-30bd-7a0a-bdd4-79eda4d83496`: "Track NRC safety and environmental review progress for UIUC KRONOS MMR microreactor" -> Resolved by updating `nano-nuclear-energy-nrc-milestone-2026`. This is a perfect mapping! Let's write the first updated note on the DOE Surplus Plutonium Utilization Program. Slug: `doe-surplus-plutonium-program-2026` Wait, let's re-read the prior note's title and description: "DOE Pivots to Fueling Advanced Reactors with Weapons-Grade Plutonium" Let's see if we have the exact text of the prior note. No, we only have its summary: "In a major regulatory and political shift in late May 2026, the U.S. Department of Energy (DOE) selected five advanced nuclear companies to begin advanced negotiations under the Surplus Plutonium..." Let's write a beautifully structured, evidence-grounded note. Let's write the note body for `doe-surplus-plutonium-program-2026`. We must make sure to include: - Name and link the actual things (the ANS article, Oklo's PR, etc.) - 1-2 representative verbatim quotes with links - Market context (Oklo OKLO /markets/OKLO/2026/06/01, Flibe, etc.) - Interpretation Let's check the OKLO market view URL: `/markets/OKLO/2026/06/01`. We can cite it. Let's construct the markdown for `doe-surplus-plutonium-program-2026`. Wait! Let's review the exact rules: "No YAML frontmatter — the title is the first `# ` heading and the slug is the slug parameter you pass." "Carry 1-2 REPRESENTATIVE VERBATIM QUOTES, copied exactly, each kept with the link it came from" "To link ANOTHER finding from a note body, write its slug as a wikilink — `[[its-slug]]`" Let's draft the first note. I will write it now.

Excellent. Let's write the second note on Nano Nuclear regulatory and corporate progress. Slug: `nano-nuclear-energy-nrc-milestone-2026` Wait, let's look at the prior note's title and description: "Nano Nuclear Energy Microreactor Design Reaches Key Regulatory Milestone with NRC" Let's see: "In late May 2026, Nano Nuclear Energy Inc. (NASDAQ: NNE) achieved a critical regulatory milestone when the U.S. Nuclear Regulatory Commission (NRC) formally accepted a construction permit application..." Let's write an updated note for this slug. Let's include: - NNE's KRONOS MMR construction permit application (CPA) formal acceptance by the NRC on May 20, 2026. - Partnership with the University of Illinois Urbana-Champaign (U. of I.) Grainger College of Engineering. - CPA was submitted on March 31, 2026. - Review timeline: Completion estimated in 2027, with construction starting in the second half of 2027. - NNE's $13 million acquisition of Secured Transportation Services LLC (STS) on May 22, 2026 (announced May 26, 2026). - STS brings over 20 years of nuclear materials logistics experience, holds approvals for over 90% of active U.S. NRC spent fuel routes, and generated $7.1M in revenue and $1.3M in net income in 2025, providing NNE with its first revenue-generating operations. - Cite the NNE market view: `/markets/NNE/2026/06/01`. NNE has $197.7 million in cash, a market cap of $1.50 billion, and its stock is up 26.9% over the past month. Let's write this note body. I will call `write_note` now.

Excellent. Now let's write the third note on Uranium Pricing and Supply Constraints. Slug: `uranium-pricing-supply-constraints-2026` Wait, let's look at the prior note's title and description: "Uranium Contract Prices Reach Multi-Year Highs Amid AI-Driven Demand and Supply Constraints" Let's see: "Uranium market dynamics in 2026 reflect a widening supply-demand gap, driven by the massive power requirements of artificial intelligence data centers, regulatory easing, and corporate commitments to..." Let's write an updated note for this slug. Let's include: - Long-term contracting boom: Utilities are aggressively locking in multi-year supply contracts well ahead of production. - Denison Mines Corp (DNN) as a prime example: in Q1 2026, DNN announced long-term contracts to sell 550,000 lbs of uranium for delivery between Q2 2026 and Q1 2027 at an average price of nearly $99 per pound. - As of Q1 2026, Denison has committed 1.35 million lbs for delivery between Q2 2026 and Q2 2027, with 0.95 million lbs fixed at an average price of $92.05 per pound. Denison has secured firm sales commitments for nearly 8 million lbs of uranium from physical holdings and future production from its flagship Wheeler River (Phoenix) project, which is not targeted to begin production until mid-2028. - Cameco Corporation (CCJ): reported strong Q1 2026 earnings of $0.47 per share (beating the $0.34 analyst estimate) on $845.4 million in revenue, supported by the full restart of its Key Lake mill and McArthur River mine following a labor dispute. CCJ has a marketcap of $49.08B. - Uranium Energy Corp (UEC): scheduled to report fiscal Q4 2026 earnings on June 1, 2026, with an expected GAAP EPS loss of $-0.05. UEC's production timeline "keeps shifting while the market pretends not to notice," highlighting the execution risks and premium valuations of development-stage producers in the sector (UEC trades at a premium with a $13.77 share price). - Market indicators: UEC's 200-day moving average is being tested at $13.81. - Cite the market views for CCJ (`/markets/CCJ/2026/06/01`) and UEC. Let's write this note body. I will call `write_note` now.

Excellent. Now let's resolve the two open threads using `resolve_thread`. For the first thread (`019e84fb-3fbe-7cd1-a749-e2fcb9753199`): "Monitor advanced negotiations and fuel agreements under the DOE Surplus Plutonium Utilization Program" We will resolve it and point to `[[doe-surplus-plutonium-program-2026]]`. Let's perform this.

Now for the second thread (`019e84fb-30bd-7a0a-bdd4-79eda4d83496`): "Track NRC safety and environmental review progress for UIUC KRONOS MMR microreactor" We will resolve it and point to `[[nano-nuclear-energy-nrc-milestone-2026]]`. Let's perform this.

Now I will call `finish_cycle` to complete this research cycle. Since we wrote three substantive updates to existing findings, we do not need to provide a `no_findings_reason`. Let's execute this.

I have successfully completed the research cycle, updated the key prior findings with high-quality evidence, resolved the open threads, and concluded the cycle. Here is a summary of the findings and updates made in this cycle: ### 1. **DOE Surplus Plutonium Utilization Program** * **Finding Update:** `[[doe-surplus-plutonium-program-2026]]` * **Summary:** In late May 2026, the U.S. Department of Energy (DOE) selected five advanced nuclear companies to begin advanced negotiations under the **Surplus Plutonium Utilization Program (SPUP)**. Under President Trump's Executive Order 14302, the program aims to make up to 20 metric tons of Cold War-era weapons-grade plutonium available for advanced reactor fuel recycling. The selected companies are **Oklo (NYSE: OKLO)**, **Flibe Energy**, **Exodys Energy**, **SHINE Technologies**, and **Standard Nuclear**. * **Key Details:** Oklo is partnering with European developer **Newcleo** to build a $1.68B fuel facility in Oak Ridge, TN. Meanwhile, Flibe is studying electrochemical reprocessing methods for its thorium technology. The program has faced political pushback from congressional Democrats (including Sen. Ed Markey) citing proliferation concerns. * **Resolution:** Resolved the thread monitoring the DOE SPUP negotiations. ### 2. **Nano Nuclear Regulatory & Corporate Milestones** * **Finding Update:** `[[nano-nuclear-energy-nrc-milestone-2026]]` * **Summary:** **Nano Nuclear Energy (NASDAQ: NNE)** reached two major regulatory and corporate milestones. On May 20, 2026, the NRC formally accepted the Construction Permit Application (CPA) for NNE's **KRONOS MMR** microreactor to be built at the University of Illinois Urbana-Champaign (U. of I.). The formal review is expected to conclude in 2027, with construction slated for late 2027. * **Corporate Integration:** To solve fuel transport bottlenecks, Nano Nuclear acquired **Secured Transportation Services (STS)** on May 22, 2026, for up to $13 million. STS holds approvals for over 90% of active U.S. spent nuclear fuel routes and generated $7.1M in revenue and $1.3M in net income in 2025, turning NNE into a vertically integrated, revenue-positive company. * **Resolution:** Resolved the thread tracking the NRC safety and environmental review progress for the UIUC KRONOS MMR. ### 3. **Uranium Pricing & Sourcing Dynamics** * **Finding Update:** `[[uranium-pricing-supply-constraints-2026]]` * **Summary:** Nuclear utilities are aggressively locking in multi-year fuel contracts, driving uranium prices to multi-year highs. * **Corporate Performance:** * **Denison Mines (NYSE: DNN):** In Q1 2026, Denison secured contracts to sell 550,000 pounds of uranium at an average price of nearly **$99 per pound**—even though its flagship Wheeler River (Phoenix) project isn't scheduled to produce until mid-2028. Denison has committed 1.35M lbs for near-term delivery, with 0.95M lbs locked at a fixed average price of **$92.05 per pound**. * **Cameco Corp (NYSE: CCJ):** Capitalized on the tight market, reporting a strong Q1 2026 earnings beat of **$0.47 per share** (vs. $0.34 expected) on $845.4 million in revenue, supported by the full restart of its Key Lake and McArthur River operations. * **Uranium Energy Corp (NYSE: UEC):** Highlighted execution risks in the sector, as UEC prepares to report an expected Q4 2026 loss of **$-0.05 per share** on June 1, 2026, amid a production timeline that "keeps shifting while the market pretends not to notice." UEC's stock is currently testing its critical 200-day moving average at $13.81.
