Tottori Prefecture nuclear safety advisory council approves safety of MOX fuel plan for Shimane Unit 2

The Tottori Prefecture Nuclear Safety Advisory Council held a meeting in Yonago City on September 6 and submitted an opinion on the MOX fuel power generation project planned by Chugoku Electric Power Co. for Unit 2 of the Shimane Nuclear Power Station. The opinion stated that, based on explanations provided by Chugoku Electric Power Co. and the Japanese government, the safety of the project can be ensured. The Shimane Nuclear Power Station is located in Matsue City, Shimane Prefecture. Chugoku Electric Power Co. plans to use mixed oxide fuel, or MOX fuel, consisting of uranium and plutonium, in Unit 2. This type of power generation is also referred to as plutonium thermal power generation in Japan. The opinion also...

French innovative nuclear company Newcleo submits regulatory engagement plan to NRC for U.S. MOX fuel plant

On August 7, 2026, France-based innovative nuclear company Newcleo submitted a Regulatory Engagement Plan (REP) to the U.S. Nuclear Regulatory Commission (NRC), paving the way for its proposed mixed oxide (MOX) fuel fabrication facility in the United States. The REP defines the framework for the company's pre-application phase with the NRC, key regulatory and technical topics, technical document submittals, and an indicative schedule. Previously, Newcleo sent a letter to the NRC on February 23 expressing its intent, and initiated pre-application interactions in March, engaging with the NRC on the design and safety approach for the LFR-AS-200 lead-cooled fast reactor and the associated MOX plant; last month, it had already submitted the REP for the LFR-AS-200 (200 MWe commercial version). Newcleo stated that this submission is a step toward advanced...

Newcleo Initiates U.S. Regulatory Pre-Application Engagement for MOX Fuel Facility, Accelerating Advanced Reactor Fuel Supply Chain Development

Advanced reactor and nuclear fuel company Newcleo has initiated regulatory pre-application engagement with the U.S. Nuclear Regulatory Commission (NRC) for a mixed oxide (MOX) fuel fabrication facility, with plans to advance construction at the Savannah River Site in South Carolina. This move indicates that the company is not only advancing the licensing of its advanced reactor itself but also seeking to establish supporting fuel supply capabilities in parallel, aiming to mitigate fuel bottlenecks in future commercial deployment. The submitted regulatory engagement plan represents a key step prior to formal license application, with the core objective of communicating with regulators in advance on facility design, safety standards, review scope, and key technical issues. Newcleo previously submitted its regulatory engagement plan for the LFR-AS-200 lead-cooled fast reactor to the NRC in July...

Japan's Plutonium Stockpile Expected to Remain at 44.4 Tons by End of 2025

Japan's Cabinet Office reported to the Japan Atomic Energy Commission (JAEC) on August 5 that Japan's plutonium stockpile is expected to be 44.4 tons by the end of 2025, unchanged from the end of the previous year. By source, domestically sourced plutonium stockpile is expected to be 9.9 tons, while overseas-sourced plutonium stockpile is 34.5 tons. The overseas-sourced plutonium mainly comes from separated plutonium formed after Japan entrusted its spent fuel reprocessing operations to the United Kingdom and France. The report shows that in 2024, Kansai Electric Power Company (KEPCO) processed 1.3 tons of plutonium stored in France into mixed uranium-plutonium oxide fuel, namely MOX fuel, resulting in a decrease in overseas-sourced plutonium stockpile. Subsequently, this batch of MOX fuel was shipped to the Takahama Nuclear Power...
