Cycle on Jul 13, 2026

I will begin by listing the open threads on this topic to understand what past cycles have decided to monitor or resolve, and then retrieve public-markets data for key players in the nuclear ecosystem (e.g., Cameco, NuScale, Oklo, Nano Nuclear, Constellation, Vistra, Southern Company) to ground our analysis. Let's list the threads first.

I see three active threads/watches: 1. Oklo's Groves Isotope Test Reactor targeting first criticality in July 2026. 2. Nano Nuclear Energy (NNE) appointing a permanent CTO / Head of Reactor Development (following the termination of Dr. Florent Heidet on June 22, 2026). 3. NRC ruling on Nano Nuclear's KRONOS Construction Permit Application (estimated 2027). Let's begin by searching for recent news regarding Oklo's Groves Isotope Test Reactor and Nano Nuclear Energy's CTO appointment to see if either of these watches has fired or has updates. I will also check public-markets data for key nuclear companies: Cameco (CCJ), Oklo (OKLO), Nano Nuclear Energy (NNE), NuScale Power (SMR), Constellation Energy (CEG), and Vistra Corp (VST). First, let's pull market views for OKLO, NNE, and CCJ to see their current market standing and recent news.

The market view for OKLO shows: - Current price: $48.85 (as of July 13, 2026). - Operating loss: $51.2 million for Q1 ending March 31, 2026. - Total cash: $1.59 billion as of March 31, 2026. - News: "Oklo Inc. (NYSE: OKLO) Secures Key DOE Safety Approval For Groves Isotope Test Reactor, Targeting First Criticality This Month" (published July 8, 2026). This is highly relevant to our watch `019f3681-0a81-7257-95cb-7bf1f45c20b3` ("Oklo Groves Isotope Test Reactor Achieves First Criticality"). Let's check if the first criticality has been achieved yet, or if they are still in the pre-startup review phase. Let's also pull the market views for NNE (Nano Nuclear Energy) and CCJ (Cameco).

Let's pull CCJ (Cameco).

Let's check the utility-side companies: Constellation Energy (CEG) and Vistra Corp (VST). Let's pull their market views. This will give us a complete picture of the public nuclear valuations.

Let's pull VST (Vistra Corp) and SMR (NuScale Power). This will cover the core companies.

Let's pull SMR (NuScale Power). This will complete our public-markets check of the key players.

Now, let's look for specific updates on: 1. Oklo's Groves Isotope Test Reactor achieving first criticality or starting up (since they targeted July 2026 and we saw they got key safety approval on July 8, 2026). 2. Nano Nuclear Energy's CTO appointment. 3. Uranium spot prices / long-term contract pricing trends. 4. Any other nuclear regulatory developments, corporate PPAs, or political/policy moves in July 2026. Let's run a web search for Oklo Groves Isotope Test Reactor first.

Let's fetch the BusinessWire article from July 1, 2026: `https://www.businesswire.com/news/home/20260701843499/en/U.S.-Department-of-Energy-Approves-Final-Safety-Analysis-for-Oklos-Groves-Isotope-Test-Reactor-Advancing-the-Project-Toward-Operational-Authorization` to get the exact details on this DOE safety approval, and then we will search to see if they actually reached criticality yet (since today is July 13, 2026). Let's fetch the page first.

That is a very detailed update! The DSA (Documented Safety Analysis) was approved on July 1, 2026. The next steps before first criticality are the readiness review and startup approval, followed by fuel loading. Oklo is targeting first criticality for Groves in July 2026. Let's do a search to see if they have announced first criticality since July 1, 2026. Today is July 13, 2026. Let's see if there is any newer press release or news.

Let's do a broader search on Oklo Groves Criticality to see if there is any other news. No other press release on Oklo's site since July 1, 2026. This means the reactor has not achieved first criticality yet, but is currently in the "final pre-startup review" phase (readiness review, startup approval, fuel loading) targeting first criticality in July 2026. This means the watch `019f3681-0a81-7257-95cb-7bf1f45c20b3` ("Oklo Groves Isotope Test Reactor Achieves First Criticality") is still active and has NOT fired yet, but we have a major update on it (the approval of the DSA on July 1, 2026). Let's search for Nano Nuclear Energy (NNE) and see if they have appointed a permanent CTO or Head of Reactor Development. Let's do a search.

Let's fetch the page: `https://nanonuclearenergy.com/nano-nuclear-highlights-global-strategic-engagements-across-emerging-nuclear-markets-and-management-team-updates/` to see the details of the management team updates and whether a permanent CTO has been named.

Okay, the press release from June 24, 2026, states that: - Dr. Florent Heidet, CTO and Head of Reactor Development, departed the company. - CEO James Walker took over as Interim Head of Reactor Development. - Prof. Massimiliano Fratoni (Senior Director and Head of Reactor Design) took on an expanded role to support KRONOS MMR development. Let's search to see if they've appointed a permanent CTO since then (June 24 to July 13, 2026). Let's do a search.

Let's search Google more broadly for any news of Nano Nuclear Energy appointing a permanent CTO or Head of Reactor Development. Let's do a search.

It appears that NNE has not appointed a permanent CTO or Head of Reactor Development yet. James Walker remains the Interim Head of Reactor Development, and Prof. Massimiliano Fratoni is providing KRONOS program support. This means the watch `019f1270-ea9c-7592-a45b-2eb33c4aa5a0` ("Nano Nuclear Energy Appoints Permanent CTO / Head of Reactor Development") has NOT fired yet and should remain open. Let's look for: 1. Uranium spot and long-term contract pricing trends in June/July 2026. 2. Any major corporate nuclear PPAs or licensing decisions in June/July 2026. Let's do a web search.

Let's fetch the InvestingNews article on "Uranium Price Trends: Q2 2026 Review and Forecast" (`https://investingnews.com/uranium-forecast/`) to see what the latest uranium spot price and long-term contract pricing trends are in June/July 2026. This will give us a very solid foundation for our uranium supply finding.

Wait, that page is just an overview/profile of the editor and some basic market numbers, let's see if there are other URLs or if we can find the actual content of the uranium price trends Q2 2026. Let's do a search on `site:investingnews.com "uranium" "2026"` to find the article.

Excellent! Let's fetch the first article "Uranium Price Trends: Q2 2026 Review and Forecast" (`https://investingnews.com/uranium-forecast/`) again or search for its core content. Wait, the fetch did not show the article text, it just showed the editor bio because the page might have had some layout that put the bio first. Let's look at the description: "While spot uranium traded near US$85 during the quarter, long-term contract prices continued to climb. Since June 2025, the long-term price has...". Let's also look at "Uranium Market Reset: Consolidation Today, Deficit Tomorrow" (`https://investingnews.com/brooke-thackray-uranium-market-forecast/`) and fetch that to see what the trends are. Let's fetch it first.

Let's try a search to get a clean text summary of the current uranium price in mid-2026. Let's do a search on `"uranium spot price" AND ("85" OR "84" OR "86") 2026` or search for Cameco's uranium price chart. Let's do a search.

Let's fetch the Crux Investor article: `https://www.cruxinvestor.com/posts/uranium-market-outlook-2026-navigating-uncertainty-and-investment-strategy` to learn more about the uranium market outlook in 2026. This will give us a very rich, highly relevant source.

This is a very high quality source. It was published very recently (as of July 13, 2026, 04:08 EDT). Let's extract the key takeaways: - Spot uranium prices are trading in the $80 to $150 range, currently consolidation is happening around $85/lb (as of June/July 2026). - Utilities contracted for around 82-85 million pounds in 2025, but there is a major gap compared to the annual replacement needs of 150-180 million pounds. - Estimated global inventory is around 300 million pounds, but much of it is immobile (locked in China and India). Utilities maintain about 1-2 years of working inventory. - Expected market "reset" in late 2026 or early 2027 as utility inventory buffers deplete, leading to a higher pricing plateau due to supply-side fragility and the long timelines required for permitting and development. Let's do a search on recent uranium long-term contract pricing to see if we can get a specific figure for long-term contracts. Let's do a search.

This is incredibly detailed and useful! Let's fetch the ANS article "Uranium prices reflect strong outlook, raise supply questions" (`https://www.ans.org/news/article-8000/uranium-prices-reflect-strong-outlook-raise-supply-questions/`) to verify specific quotes and numbers. Wait, let's also fetch the TradeTech press release or a related article on `https://www.uranium.info/press_releases.php` or `https://www.ans.org/news/article-8000/uranium-prices-reflect-strong-outlook-raise-supply-questions/`. Let's fetch the ANS article first.

This is an exceptionally solid source. Let's look at the key details: - Spot price: End of April 2026 spot price was $86.35/lb (up from $84.25/lb in March, but down from $94.28/lb in January 2026). - Long-term contract price: By the end of Q1 2026, the long-term contract price for uranium was sitting at US$90 per pound of U3O8 (highest level since 2008). - Let's check if there are newer long-term contract prices. On July 1, 2026, TradeTech's Long-Term Uranium Price reached $97.00/lb (highest price in 18 years, or historical high). Let's search to confirm TradeTech's July 1, 2026 price of $97.00/lb. Let's do a search.

Let's fetch the EIN News article about the $97.00/lb price: `https://www.einnews.com/pr_news/923690861/long-term-uranium-price-reaches-historical-high-of-97-00` to get the exact details of TradeTech's July 1, 2026 announcement. This will be a great data point.

Ah, the search budget is spent. That is perfectly fine, we have gathered exceptionally rich, precise, and highly detailed information on: 1. **Uranium supply and contract pricing:** We have TradeTech's July 1, 2026 press release showing the Long-Term Uranium Price Indicator hitting $97.00/lb (the highest in 18 years, up $10.00 since Dec 31, 2025). Spot uranium is consolidating in the mid-$80s (e.g., $86.35/lb in end-of-April 2026, up from $84.25/lb in March, down from $94.28/lb in January). 2. **Oklo's Groves Isotope Test Reactor:** We have the BusinessWire release from July 1, 2026, showing that the U.S. Department of Energy (DOE) approved the Documented Safety Analysis (DSA) for Oklo's Groves Isotope Test Reactor in Texas. The project is moving into the final pre-startup review phase (readiness review, startup approval, fuel loading) and targeting first criticality in July 2026. This is a massive milestone! 3. **Nano Nuclear Energy (NNE) Management Updates:** We have NNE's June 24, 2026 press release confirming that Dr. Florent Heidet, CTO and Head of Reactor Development, departed the company. CEO James Walker has stepped in as Interim Head of Reactor Development. Prof. Massimiliano Fratoni is providing KRONOS program support. Let's write down these notes! Wait, are there existing slugs we should reuse? Let's see our relevant prior findings: - `doe-surplus-plutonium-program-2026` - `corporate-nuclear-power-purchase-agreements` - `nano-nuclear-energy-nrc-milestone-2026` - `doe-17-5b-nuclear-supply-chain-loans-2026` - `meta-vistra-nuclear-ppa-2026` Let's check if we have any other notes by calling `read_notes` to make sure we don't duplicate slugs or miss any existing ones. This is a very important step. Let's call `read_notes` for the topic.

This is beautiful! Let's examine the existing slugs: - `oklo-groves-reactor-doe-safety-approval-2026`: This exists! It's titled "Oklo Secures Key DOE Safety Approval for Groves Reactor, Targeting July 2026 Criticality". We can update this note to reflect the July 1, 2026 approval of its Documented Safety Analysis (DSA) and progress toward first criticality. - `nano-nuclear-energy-nrc-milestone-2026`: This exists! It's titled "Nano Nuclear Energy Jumps on UAE Investment Talks Amid Russell Index Exit and Leadership Vacancy". We can update this note to detail the departure of Dr. Florent Heidet, CEO James Walker stepping in as Interim Head of Reactor Development, and Prof. Massimiliano Fratoni providing program support. - `uranium-pricing-supply-constraints-2026`: This exists! It's titled "Uranium Market Consolidates as Cameco and Orano Close Cigar Lake Mine Buyout from TEPCO". We can update this note to detail the latest uranium market pricing: TradeTech's Long-Term Uranium Price Indicator hitting $97.00/lb on June 30, 2026 (announced July 1/2, 2026) and spot uranium consolidating in the mid-$80s, along with the supply-demand deficit dynamics. Let's update these three notes! First, let's update `oklo-groves-reactor-doe-safety-approval-2026`. Let's see the current content of `oklo-groves-reactor-doe-safety-approval-2026` by reading it. Wait, can we read it? If we have its slug, we can overwrite/update it. To be precise, let's write the updated note with the same slug. Let's make sure we cite the `/markets/OKLO/2026/07/13` URL since we pulled the OKLO market view. Let's write the finding for OKLO first. We will use the slug `oklo-groves-reactor-doe-safety-approval-2026`. Let's draft it carefully. We must name and link the actual BusinessWire article and include verbatim quotes. Let's write the note.

Now let's update `nano-nuclear-energy-nrc-milestone-2026` to document the departure of CTO Dr. Florent Heidet and CEO James Walker stepping in as Interim Head of Reactor Development. We will also incorporate the NNE market view data (as of July 13, 2026). Let's write this note.

Now let's update `uranium-pricing-supply-constraints-2026` to detail the latest uranium market pricing: TradeTech's Long-Term Uranium Price Indicator hitting $97.00/lb on June 30, 2026 (announced July 1/2, 2026) and spot uranium consolidating in the mid-$80s, along with the supply-demand deficit dynamics. We will also incorporate the CCJ (Cameco) market view data. Let's write this note.

These updates are excellent and cover all the key developments! Now, let's look at the active watches/threads: 1. `019f3681-0a81-7257-95cb-7bf1f45c20b3` ("Oklo Groves Isotope Test Reactor Achieves First Criticality"): The reactor has not achieved criticality yet (it is currently in the "final pre-startup review" phase, targeting criticality in July 2026). Let's keep this watch open. 2. `019f1270-ea9c-7592-a45b-2eb33c4aa5a0` ("Nano Nuclear Energy Appoints Permanent CTO / Head of Reactor Development"): No permanent replacement has been named. James Walker is Interim Head of Reactor Development. Let's keep this watch open. 3. `019ea648-6b84-7910-aa5b-6d1378599bba` ("NRC rules on Nano Nuclear's KRONOS Construction Permit Application"): This is estimated for 2027. Let's keep this watch open. Since none of the watches have fired (neither first criticality nor a permanent CTO has been announced), we do not need to call `record_event`. And since we didn't fully resolve any open threads (as they are ongoing watches that haven't triggered yet), we do not call `resolve_thread`. We do not have any new forward-looking watches to register that aren't already covered by our existing watches (the Groves reactor criticality and KRONOS NRC permit are already registered). Let's call `finish_cycle` to complete this research cycle. This is the ONLY way to complete a cycle.

I have completed this research cycle on the resurgence of nuclear energy across public markets. Here is a summary of the key findings and updates established during this cycle: ### 1. Uranium Supply and Contract Pricing Trends * **Long-Term Contract Highs:** On **June 30, 2026** (announced July 2, 2026), TradeTech's monthly **Long-Term Uranium Price Indicator reached an 18-year historical high of $97.00 per pound** of $U_3O_8$. This represents a $10.00 increase since December 31, 2025, and reflects a major structural shift in utility contracting behavior. * **Spot Price Consolidation:** Spot uranium prices have cooled from their January 2026 peak of over $101/lb, consolidating in the **mid-$80s** (stabilizing around $85.50 to $86.50/lb in June and July 2026). * **Deficit and Inventory Dynamics:** Utilities maintain a 1-to-2-year working inventory buffer, but in 2025 they only contracted for **82 to 85 million pounds**—far below the annual global replacement requirements of **150 to 180 million pounds**. Much of the estimated 300 million pounds of global inventory is immobile (locked in sovereign stockpiles in China and India). Market analysts expect a pricing "reset" in late 2026 or early 2027 as utility working inventory buffers deplete. * **Producer Financials:** Cameco Corporation (NYSE: CCJ) reported strong Q1 2026 results, with net income rising **87.5% YoY to $131.1 million** on **$845.4 million in revenue**. Cameco holds **$772.9 million in cash** and carries a conservative Debt/EBITDA ratio of 0.8x. However, the company faces pipeline challenges into the 2030s, and analysts note that prices in the **$125 to $150 range** may be required over the next decade to incentivize enough new mining capacity. ### 2. Oklo's Groves Isotope Test Reactor Milestones * **DOE Safety Approval:** On **July 1, 2026**, the U.S. Department of Energy (DOE) approved the final **Documented Safety Analysis (DSA)** for Oklo's Groves Isotope Test Reactor in Texas under the Reactor Pilot Program. * **Criticality Timeline:** With both the preliminary and final safety analyses approved, the Groves project moves from documentation into the final pre-startup review phase (readiness review, startup approval, and fuel loading). Oklo is actively targeting **first criticality in July 2026**. * **Financial Standing:** Oklo (NYSE: OKLO) maintains a strong liquidity position with **$1.59 billion in cash** against just **$2.6 million in total debt** as of March 31, 2026. However, it continues to experience high development-phase expenses, reporting a **$51.2 million operating loss** for Q1 2026. ### 3. Nano Nuclear Energy (NNE) Leadership Changes * **CTO Departure:** On **June 24, 2026**, NNE announced that Chief Technology Officer and Head of Reactor Development, **Dr. Florent Heidet, departed the company**. * **Interim Leadership:** CEO **James Walker** has stepped in as the **Interim Head of Reactor Development**. To support continuity, **Prof. Massimiliano Fratoni** (Senior Director and Head of Reactor Design, and Chair of the Nuclear Engineering Department at UC Berkeley) has taken on an expanded leadership role, transitioning to support the development and prototyping of the flagship **KRONOS MMR™** reactor at the University of Illinois Urbana-Champaign. * **Market Pressures:** NNE remains pre-revenue, reporting a **negative $14.0 million in free cash flow** for Q1 2026, offset by **$197.7 million in cash**. Shares closed at **$18.86** on July 13, 2026 (hitting a 52-week low and trading **37.4% below its 200-day moving average**), heavily impacted by the company's removal from the Russell growth indexes in late June. ### Status of Active Watches * **Oklo Groves Criticality:** Still active and monitored. We have updated the finding `[[oklo-groves-reactor-doe-safety-approval-2026]]` to reflect the July 1, 2026 DSA approval and the pending criticality target. * **Nano Nuclear Permanent CTO:** Still active and monitored. We have updated the finding `[[nano-nuclear-energy-nrc-milestone-2026]]` to document Dr. Florent Heidet's departure and James Walker's interim role. * **KRONOS NRC Construction Permit:** Still active and monitored (expected 2027).
