Cycle on Jul 20, 2026

I will start this research cycle by listing the open threads of interest to see what questions or watches are currently pending for this topic.

I will run a web search to check the status of Oklo's Groves Isotope Test Reactor criticality in Texas, which was targeted for July 2026, and to see if Nano Nuclear Energy has appointed a permanent CTO or Head of Reactor Development.

Let's search more recently or specific news for Oklo attaining criticality in July 2026. The current date is July 20, 2026. Let's see if there are any news releases or articles about it achieving criticality around July 4, 2026 or mid-July.

Let's read the Investor's Business Daily article, "Oklo Alters Nuclear Test Deadline; Third Reactor Achieves..." or the PowerMag article about Aalo Atomics or Deployable Energy. These mention "fourth DOE-authorized advanced reactor by July 4" and "third reactor achieves...". Let's search for "Aalo Atomics" "criticality" and "Oklo" to see what happened on July 4, 2026. Let's do a search for `"Aalo Atomics" "criticality"`.

Let's fetch the Energy.gov and Aalo Atomics articles to see if Oklo's Groves also achieved criticality, or if Oklo missed the July 4/July deadline, or if it's still targeting it. Wait, the reddit thread "Disappointed in Aalo and Oklo's performance in the pilot..." might have some details, or the Energy.gov release "Department of Energy Celebrates Fourth Criticality Ahead of July 4th Goal" might explain which four reactors achieved criticality. Let's search for "Department of Energy Celebrates Fourth Criticality Ahead of July 4th Goal" or fetch the energy.gov URL. Let's do a web search for the exact energy.gov text or fetch it. Let's search first.

Let's fetch `https://www.energy.gov/articles/department-energy-celebrates-fourth-criticality-ahead-july-4th-goal` to see which four reactors hit criticality, and whether Oklo was one of them.

The four reactors that hit criticality are: 1. Antares Nuclear’s Mark-0 reactor (June) 2. Valar Atomics’ Ward 250 (June) 3. Deployable Energy’s Unity (June) 4. Aalo Atomics' Aalo-X (July 4th at 12:20 AM MDT) Oklo's Groves Isotope Test Reactor in Texas is *not* one of these four. Let's research Oklo's Groves reactor progress. Under the watch list: "Oklo is targeting first criticality for its Groves Isotope Test Reactor in Texas in July 2026, following the DOE's approval of its Documented Safety Analysis (DSA)." The fire date of the watch is July 31, 2026. The current date is July 20, 2026. Let's see if there are any updates on Oklo Groves criticality. Let's do a search for `"Groves Isotope Test Reactor" "criticality" 2026`. Or let's see if Oklo's Groves reactor has achieved criticality yet. Let's do a search.

Let's fetch Oklo's own newsroom announcement to see what the exact text of the July 1, 2026 release is: `https://oklo.com/newsroom/news-details/2026/U-S--Department-of-Energy-Approves-Final-Safety-Analysis-for-Oklos-Groves-Isotope-Test-Reactor-Advancing-the-Project-Toward-Operational-Authorization/default.aspx` Let's fetch it.

Let's search for "Oklo Altered Nuclear Test Deadline" or similar to see if there is any delay in Oklo hitting criticality. Let's do a search for `"Oklo" "criticality" "July" 2026`. Or let's search `Oklo "Groves" "criticality"` to see if there are any updates in July 2026. Let's search `Oklo "Groves" "July 4"`. Let's search `Oklo "Groves" "July 2026"`. Let's do a search.

Let's search for "Oklo Alters Nuclear Test Deadline; Third Reactor Achieves Criticality" specifically to understand why it says "Oklo Alters Nuclear Test Deadline". Is there an article on Investors.com or similar? Let's check.

Let's fetch the Investors.com article `https://www.investors.com/news/oklo-stock-doe-nuclear-test-microreactors-smrs/` to understand why it says "Oklo Alters Nuclear Test Deadline; Third Reactor Achieves Criticality" and what the delay is. Let's fetch it.

The article clarifies that Oklo's Groves Isotope Test Reactor DSA was approved on July 1, 2026, which was too late to achieve first criticality by the July 4, 2026 deadline originally targeted. Instead, Oklo is targeting first criticality for Groves "sometime in July" (specifically "in July 2026" as per Oklo's own press release). Wait, are there any updates on whether Oklo's Groves reactor has achieved criticality yet? Today is July 20, 2026. Let's search the web for any press release or social media posts from Oklo stating that Groves has achieved criticality or loaded fuel. Let's search for `Oklo Groves "criticality"` or `Oklo "criticality"` or `Oklo "loaded fuel"` or `Oklo "startup approval"`. Let's search.

It seems that as of today, July 20, 2026, Oklo has not yet announced that Groves has actually achieved criticality. The watch on `Oklo Groves Isotope Test Reactor Achieves First Criticality` has a fire date of `2026-07-31T00:00:00Z` and is a one-shot watch. Since it has not fired yet (or if there's no news of it having fired yet), I can update the thread with the latest developments (i.e. the DSA was approved on July 1, 2026, but it missed the July 4th deadline and is still targeting criticality in July 2026, currently undergoing readiness review, fuel loading, and startup approval). I should not record a fire event yet since it hasn't actually achieved criticality. Now let's look for the other watch: `Nano Nuclear Energy Appoints Permanent CTO / Head of Reactor Development` (Dr. Florent Heidet was terminated as CTO and Head of Reactor Development on June 22, 2026. CEO James Walker was appointed as Interim Head. Monitor for the announcement of a permanent replacement to lead NNE's reactor engineering and KRONOS MMR development.) Let's search for "Nano Nuclear Energy" and "CTO" or "Head of Reactor Development" or "replaces Florent Heidet" or "new CTO" or "Chief Technology Officer" to see if a permanent replacement has been announced.

Let's search more broadly for recent news about Nano Nuclear Energy to see if there is any announcement of a permanent CTO or Head of Reactor Development. Let's do a search for `"Nano Nuclear Energy"` with freshness set to "month" to see what has happened in the last 30 days.

Let's fetch the article about GAIN vouchers: `https://www.ans.org/news/article-7917/gain-vouchers-go-to-constellation-nano-nuclear-and-nucube/` to see what Nano Nuclear Energy is getting safety or engineering vouchers for. That could be highly relevant for reactor development. Let's fetch it.

Ah, the GAIN voucher article is from April 2026. The search returned it because of the dates or keywords. Let's see if there are any other recent news items about Nano Nuclear Energy from July 2026. Let's look at the press release from Globenewswire on July 17, 2026: "NANO Nuclear Energy Joins Virginia Nuclear Energy Consortium to Advance Nuclear Innovation and Support the Commonwealth’s Growing Energy Requirements." Let's fetch it or search for details. Wait, let's also search for other nuclear-related news: - Uranium pricing trends (spot and long-term contract pricing). - Corporate nuclear power purchase agreements (PPAs), especially tech companies contracting directly with nuclear operators. - Constellation Energy, Vistra, and Southern Company. Let's first pull the market views for the core companies mentioned in the brief to establish their financial and valuation baselines. Let's pull the market views for: 1. Cameco (CCJ) 2. NuScale Power (SMR) 3. Oklo (OKLO) 4. Nano Nuclear Energy (NNE) 5. Constellation Energy (CEG) 6. Vistra (VST) 7. Southern Company (SO) Let's do `market_view` for each. I'll start with CCJ, SMR, OKLO, and NNE. Let's make the calls.

Now let's pull market views for OKLO, SMR, and NNE.

Let's pull SMR and NNE.

Let's pull NNE.

Let's look at the utility side: Constellation Energy (CEG), Vistra (VST), and Southern Company (SO). Let's pull their market views. I will make three calls.

Let's pull VST and SO. I will make two calls.

Let's pull SO. I will make one call.

Ah, the search budget is spent. No more searches can be made. Let's see what we have gathered so far: 1. **Oklo's Groves Isotope Test Reactor**: - The U.S. Department of Energy (DOE) approved the Documented Safety Analysis (DSA) on July 1, 2026. - This was the final safety basis for pilot testing of the Groves reactor in Lockhart, Texas under the Reactor Pilot Program. - The approval was too late to meet the tentative July 4, 2026 deadline for three advanced reactors to reach criticality (set by Executive Order 14301 in May 2025). - The four reactors that did achieve criticality by or around the July 4th deadline under the Reactor Pilot Program are: 1. Antares Nuclear’s Mark-0 reactor (June 2026) 2. Valar Atomics’ Ward 250 (June 2026) 3. Deployable Energy’s Unity (June 2026) 4. Aalo Atomics' Aalo-X (July 4, 2026 at 12:20 AM MDT) - Oklo has pushed back its testing timeline to "sometime in July" (July 2026). Currently, Groves is in the final phase before startup, which includes DOE's readiness review, fuel loading, and startup approval. - This is highly relevant to the watch `Oklo Groves Isotope Test Reactor Achieves First Criticality`. The target was July 2026, and since it has not reached criticality yet, I will not record a fire event yet, but I can write a detailed update finding. Let's see if there is an existing slug we can use or update. - From the relevant prior findings: - `uranium-pricing-supply-constraints-2026` - `nano-nuclear-energy-nrc-milestone-2026` - `doe-surplus-plutonium-program-2026` - `corporate-nuclear-power-purchase-agreements` - `doe-17-5b-nuclear-supply-chain-loans-2026` Wait, does Oklo have an existing note slug? Let's read notes to see if there is any other note about Oklo or SMRs. I will call `read_notes` to see all available notes.

Ah! This is great. We have existing notes: - `doe-reactor-pilot-program-criticality-race-2026`: "DOE Reactor Pilot Program Achieves Criticality Deadline Success with Third Advanced Reactor" - `oklo-groves-reactor-doe-safety-approval-2026`: "Oklo Secures Key DOE Safety Approval for Groves Reactor, Targeting July 2026 Criticality" - `nano-nuclear-energy-nrc-milestone-2026`: "Nano Nuclear Energy Jumps on UAE Investment Talks Amid Russell Index Exit and Leadership Vacancy" Let's update `doe-reactor-pilot-program-criticality-race-2026` and `oklo-groves-reactor-doe-safety-approval-2026`. Wait, let's look at `doe-reactor-pilot-program-criticality-race-2026` first. In June, three reactors hit criticality (Antares' Mark-0, Valar's Ward 250, and Deployable Energy's Unity). And on July 4, 2026, a *fourth* reactor achieved criticality under the DOE Reactor Pilot Program: Aalo Atomics' Aalo-X! This exceeded the White House goal of "three reactors by July 4, 2026" (it delivered four!). This is a massive milestone. Let's look at `oklo-groves-reactor-doe-safety-approval-2026`. The note says: "Oklo Secures Key DOE Safety Approval for Groves Reactor, Targeting July 2026 Criticality". We can update it because we now know: - The DSA was approved on July 1, 2026, which was too late for the July 4th deadline (set by Executive Order 14301). - Oklo has pushed back its testing timeline to "sometime in July" (July 2026). - Currently, Groves is in the final phase before startup: DOE's readiness review, fuel loading, and startup approval. - We can include the market context for OKLO (stock price has declined significantly, hitting a 52-week low of $41.11, down 30.1% over the last month and 76.4% below its 52-week high, amid broader sector sell-offs as investors demand real results over AI hype). Let's look at `nano-nuclear-energy-nrc-milestone-2026`. We can update it with: - Nano Nuclear Energy (NNE) has joined the Virginia Nuclear Energy Consortium (VNEC) on July 17, 2026, to advance microreactor innovation and support the state's growing energy needs (particularly AI data centers). CEO James Walker will join the VNEC Board of Directors. - Nano Nuclear Energy's stock (NNE) has also faced significant downward pressure, declining 36.7% over the past month to $16.03, which is a 52-week low (71.7% below its 52-week high). Wall Street Zen recently downgraded NNE to a "Strong Sell" rating on July 18, 2026, reflecting investor skepticism and a broader market shift away from speculative nuclear/SMR plays toward tangible results. - No announcement of a permanent CTO / Head of Reactor Development has been made yet; CEO James Walker remains the Interim Head since Dr. Florent Heidet was terminated on June 22, 2026. Wait, let's write or update these notes. First, let's update `doe-reactor-pilot-program-criticality-race-2026`. Let's see what the current content of `doe-reactor-pilot-program-criticality-race-2026` is. Let's fetch it or read it if we can. Wait, `read_notes` only gives the preview. Is there a way to fetch the full body of a note? No, but we can overwrite or update it with `write_note`. Let's re-compose the note body using our newly fetched information. Wait, let's look at the sources we fetched for the DOE Reactor Pilot Program: - `https://www.energy.gov/articles/department-energy-celebrates-fourth-criticality-ahead-july-4th-goal` - Title: "Department of Energy Celebrates Fourth Criticality Ahead of July 4th Goal" - Date: July 6, 2026 - Quotes: - “President Trump asked for three advanced reactors to be authorized and achieve criticality by the 250th anniversary of our great country. I’m pleased to share that through the dedication and hard work of Aalo, INL and DOE, we have surpassed that ask and delivered four!” — U.S. Energy Secretary Chris Wright. - “The hardest problem in nuclear was never the physics, our country simply forgot how to build. The success of the Department of Energy Reactor Pilot Program is proof America can execute again,” said Yasir Arafat, President and CTO, Aalo Atomics. - "Early Saturday, as part of the U.S. Department of Energy (DOE) Reactor Pilot Program, Aalo Atomics’ test reactor, Aalo-X, successfully completed a zero-power fueled criticality demonstration." Let's construct the updated note for `doe-reactor-pilot-program-criticality-race-2026`. Wait! Is there an existing note for `oklo-groves-reactor-doe-safety-approval-2026`? Yes. Let's check the sources for Oklo: - `https://oklo.com/newsroom/news-details/2026/U-S--Department-of-Energy-Approves-Final-Safety-Analysis-for-Oklos-Groves-Isotope-Test-Reactor-Advancing-the-Project-Toward-Operational-Authorization/default.aspx` - Date: July 1, 2026 - Title: "U.S. Department of Energy Approves Final Safety Analysis for Oklo's Groves Isotope Test Reactor, Advancing the Project Toward Operational Authorization" - Quotes: - "The remaining steps are DOE’s readiness review and startup approval. Following startup approval, the facility will be authorized to receive and load nuclear fuel, conduct startup testing, and proceed toward first criticality... Oklo is targeting first criticality for Groves in July 2026." - "Groves is that demonstration. It is the first advanced reactor project to receive approval of its Documented Safety Analysis that is on privately owned land, with wholly commercially sourced fuel, equipment, and systems delivered by the private sector." — Jacob DeWitte, Oklo co-founder and CEO. - And Investor's Business Daily: `https://www.investors.com/news/oklo-stock-doe-nuclear-test-microreactors-smrs/` - Title: "Oklo Stock Gains On DOE Approval; Third Reactor Achieves Criticality" - Date: July 1, 2026 - Quotes: - "The approval comes too late for the test to meet the DOE's tentative July 4 deadline... Oklo pushed back the testing timeline to sometime in July." - "Oklo stock initially rose 3.8% early Wednesday, then eased to a 2.3% gain. Shares ended Tuesday 73% below the stock's high from October, and down about 7% over the past 12 months." - Let's also include the market view of OKLO: - Market cap: $7.15B - Stock price: $41.11 (as of July 20, 2026), hitting a 52-week low (0.0% of its 52-week position, down 76.4% from its 52-week high, and down 30.1% over the past month). - Cited URL: `/markets/OKLO/2026/07/20` Let's do this. Let's write the note for `doe-reactor-pilot-program-criticality-race-2026`. Wait, let's write `doe-reactor-pilot-program-criticality-race-2026` first. Let's make sure it has the correct structure. No frontmatter, first heading is `# <Title>`, then body, then `## Sources`. Let's write it.

Now let's update `oklo-groves-reactor-doe-safety-approval-2026`. Wait, let's write the updated note for Oklo's Groves reactor. Let's include the details on: - DSA approval on July 1, 2026. - Missing the July 4th deadline (too late for the original target of July 4th). - Pushing back the timeline to "sometime in July" (July 2026). - The remaining steps: readiness review, fuel loading, and startup approval. - Highlighting that Groves is the first project to receive DSA approval on privately owned land, with commercially sourced fuel and systems, and private-sector operations under DOE oversight. - The market context: OKLO stock hitting a 52-week low of $41.11 as of July 20, 2026, dropping 30.1% over the past month, reflecting a broader sector sell-off as investors demand tangible results over AI-driven nuclear hype. Let's cite `/markets/OKLO/2026/07/20`. Let's write this note.

Now let's update `nano-nuclear-energy-nrc-milestone-2026`. Let's see what we can include in the update for Nano Nuclear Energy: - Membership in the Virginia Nuclear Energy Consortium (VNEC) announced on July 17, 2026. This is a strategic move, as Virginia is the epicenter of the data center industry (Northern Virginia is the largest data center market in the world). Joining VNEC allows NNE to position its portable microreactors (KRONOS) for data center power needs. James Walker, CEO and Interim Head of Reactor Development, will join the VNEC Board of Directors. - Management structure update: No permanent CTO / Head of Reactor Development has been announced yet since the termination of Dr. Florent Heidet on June 22, 2026. James Walker continues as the Interim Head of Reactor Development. - Market context: NNE shares have declined 36.7% over the past month to $16.03 (as of July 20, 2026), which is its 52-week low (71.7% below its 52-week high of $56.6). The company carries a market cap of $835.5 million and reports $0 in revenue with a net loss of $9.2 million for the quarter ending March 31, 2026. Wall Street Zen downgraded NNE to a "Strong Sell" on July 18, 2026, amid a broader market correction for speculative nuclear plays. Let's cite `/markets/NNE/2026/07/20`. Let's write this note.

Now let's review the other notes we have and see if we can update them or add new ones. Let's see: - `uranium-pricing-supply-constraints-2026`: "Uranium Market Consolidates as Long-Term Contract Prices Hit Historical High of $97" Let's look at Cameco (CCJ) market view: - CCJ shares have declined 26.6% over the last three months to $85.62, leaving the stock 36.1% below its 52-week high. - Despite an 87.5% YoY earnings increase for the quarter ending March 31, 2026, the company reported negative FCF of $100.0 million. - The company recently restarted its Cigar Lake mine in northern Saskatchewan after a temporary suspension caused by challenges at Orano's McClean Lake mill. - Cameco invites investors to its Q2 2026 conference call on Friday, July 31, 2026. Let's check if we can update the uranium pricing or Cameco note. Wait, is there a note specifically on Cameco, or is it covered in `uranium-pricing-supply-constraints-2026`? Let's check the preview of `uranium-pricing-supply-constraints-2026`: "The global uranium market is experiencing a significant divergence between near-term spot price consolidation and a powerful upward surge in long-term contract pricing. On June 30, 2026, industry..." Let's update `uranium-pricing-supply-constraints-2026` to include: - Cameco's recent operational update: In July 2026, Cameco announced that its Cigar Lake mine resumed production activities after a temporary suspension caused by challenges at Orano’s McClean Lake mill. The mill has restarted operations. - Cameco's financial and stock performance: CCJ shares have declined 26.6% over the last three months to $85.62, leaving the stock 36.1% below its 52-week high, despite an 87.5% YoY earnings increase for the quarter ending March 31, 2026 (reporting net income of $131.1M and EBITDA of $252.8M). - Cameco's Q2 2026 conference call is scheduled for Friday, July 31, 2026, which will be a key event to monitor for updated long-term contract pricing trends and supply outlooks. Let's cite `/markets/CCJ/2026/07/20`. Let's write this updated note.

Let's check if we can register or update any watches. Under `list_threads` we had: - `Oklo Groves Isotope Test Reactor Achieves First Criticality` (id: `019f3681-0a81-7257-95cb-7bf1f45c20b3`). It is targeting criticality in July 2026. Since the current date is July 20, 2026, and criticality has not yet been achieved, the watch remains open. - `Nano Nuclear Energy Appoints Permanent CTO / Head of Reactor Development` (id: `019f1270-ea9c-7592-a45b-2eb33c4aa5a0`). This remains open since James Walker is still the Interim Head and no permanent CTO has been announced. - `NRC rules on Nano Nuclear's KRONOS Construction Permit Application` (id: `019ea648-6b84-7910-aa5b-6d1378599bba`). This remains open (estimated review finish in 2027). Let's register a new watch for Cameco's Q2 2026 earnings call on July 31, 2026. This is a recurring scheduled release (ongoing) or a dated catalyst (one-shot). Let's register it as a dated catalyst since it's a specific upcoming event on July 31, 2026. Wait, let's call `record_watch` for Cameco's Q2 earnings call. Let's make the call.

This is great! We have registered the watch. Now let's check if there are any other threads we can resolve or update. Wait, let's look at the open threads again: - `Oklo Groves Isotope Test Reactor Achieves First Criticality` (id: `019f3681-0a81-7257-95cb-7bf1f45c20b3`) - `Nano Nuclear Energy Appoints Permanent CTO / Head of Reactor Development` (id: `019f1270-ea9c-7592-a45b-2eb33c4aa5a0`) - `NRC rules on Nano Nuclear's KRONOS Construction Permit Application` (id: `019ea648-6b84-7910-aa5b-6d1378599bba`) Since none of these have fired yet, they remain open and we cannot resolve them. Let's double-check if we missed any other important market developments. We pulled: - CCJ: trading at $85.62, down 26.6% in 3mo, 36.1% off high. Q1 net income $131.1M (+87.5% YoY), FCF $-100.0M. Cigar Lake resumed on July 15. - OKLO: trading at $41.11 (52-week low, -76.4% off high). Q1 FCF $-50.7M. Obtained Groves DSA approval on July 1, missed July 4th deadline, targeting July criticality. - SMR: trading at $7.72 (52-week low, -85.6% off high). Q1 FCF $-316.2M. TTM revenue $18.7M (-95.8% YoY). - NNE: trading at $16.03 (52-week low, -71.7% off high). Q1 FCF $-14.0M. Joined VNEC on July 17. No permanent CTO yet.

Secured ~$1.296B run-rate from PJM capacity auction. Expanded accounts receivable facility to $1.25B on July 18. - SO: trading at $95.30 (near 52-week high, -2.5% off high). Q1 revenue $8.40B (+8.0% YoY), net income $1.36B (-0.8% YoY). Georgia Power pledged on July 20 to protect customer bills from data centers. This is a comprehensive, highly detailed market update on the entire nuclear value chain. We have updated three notes: 1. `doe-reactor-pilot-program-criticality-race-2026` 2. `oklo-groves-reactor-doe-safety-approval-2026` 3. `nano-nuclear-energy-nrc-milestone-2026` 4. `uranium-pricing-supply-constraints-2026` These updates capture all recent developments in: - Reactor pilot program criticality achievements (Aalo-X achieving criticality on July 4, 2026). - Oklo's Groves reactor progress (DSA approval on July 1, missed July 4th deadline, targeting July criticality, and stock performance). - Nano Nuclear's regional expansion (joining VNEC on July 17), leadership status, and stock performance/downgrade. - Uranium pricing and Cameco's operational restart (Cigar Lake on July 15) and upcoming Q2 call on July 31. Since we have written all relevant findings and registered our new watch, we are ready to finish the cycle. I will call `finish_cycle`.

I have completed this research cycle. I have updated four key developer-stage notes to capture the latest regulatory, corporate, and public market developments across the nuclear energy sector, and registered a new watch for Cameco's upcoming Q2 earnings call. ### Summary of Research Cycle Findings 1. **DOE Reactor Pilot Program Surpasses Goals with Aalo-X Criticality** * **What Happened:** The DOE’s Reactor Pilot Program achieved a major milestone on **July 4, 2026**, when Aalo Atomics' commercial-scale test reactor, **Aalo-X**, achieved first criticality at Idaho National Laboratory. * **Significance:** This marks the **fourth** advanced reactor to achieve criticality under the program, exceeding the target of three reactors by July 4, 2026, set under President Trump's May 2025 Executive Order 14301.
