TEPCO and JAPC invite eight power companies to participate in spent fuel transport

August 12 news, Tokyo Electric Power Company (TEPCO) and Japan Atomic Power Company (JAPC) invited eight other Japanese power companies that own nuclear power plants on the 10th to consider participating in the transport of spent fuel to the Mutsu City interim storage facility in Aomori Prefecture. Mutsu City has agreed to expand the scope of operating entities involved in the transport. The interim storage facility is operated by Recyclable-Fuel Storage Company (RFS), jointly established by TEPCO and JAPC, and is primarily used for temporary storage of spent fuel generated from nuclear power plants before reprocessing. The eight invited companies are Hokkaido Electric Power Company (Hokkai...

Japan's Mutsu Spent Fuel Interim Storage Facility May Expand Participants; KEPCO and Hokuriku Electric Power Say They Are Considering

Tokyo Electric Power Company (TEPCO) and Japan Atomic Power Company (JAPC) began contacting eight other domestic electric power companies that own nuclear power plants on August 10, asking whether they would be interested in participating in the expansion of the entities responsible for transporting spent fuel to the interim storage facility in Mutsu City, Aomori Prefecture. Among the eight companies contacted, Kansai Electric Power Company (KEPCO) and Hokuriku Electric Power Company indicated in response to the inquiries that they are considering whether to participate. In December 2025, TEPCO and JAPC had submitted a proposal to Aomori Prefecture and Mutsu City regarding the expansion of operating entities, and at that time they had also sought the intentions of these eight companies...

KEPCO KPS Q2 Results Miss Expectations; Nuclear Maintenance Demand Expected to Drive Recovery in H2

KEPCO KPS's Q2 results significantly missed market expectations, mainly due to factors such as extended long-term planned preventive maintenance cycles for nuclear power plants and a reduction in external and overseas variable works. Data shows that the company's preliminary Q2 sales stood at KRW 437.9 billion, down 3.5% year-on-year; operating profit was KRW 43.6 billion, down 33.6% year-on-year, approximately 30.1% below market consensus; net profit attributable to controlling shareholders was KRW 38.3 billion, down 24.8% year-on-year. The operating margin fell to 10.0%, down 4.5 percentage points from the same period last year, indicating pressure on both the revenue side and, to some extent, the cost side. The nuclear maintenance business was one of the key factors dragging down Q2 performance. In Q2...

Rising Seawater Temperatures Prompt New Nuclear Safety Rules: TEPCO Sets Temporary Shutdown Criteria for Kashiwazaki-Kariwa Plant

Tokyo Electric Power Company Holdings announced on August 7 that it has established a set of self-determined criteria for evaluating whether to temporarily halt nuclear reactor operations at the Kashiwazaki-Kariwa Nuclear Power Plant in Niigata Prefecture, in response to rising seawater temperatures in the surrounding area. These criteria are not mandatory requirements directly imposed by external regulatory authorities, but rather proactive measures voluntarily implemented by TEPCO based on safe operational needs. According to the conditions announced by TEPCO, the company will consider temporarily shutting down the relevant nuclear facilities when the 7-day average seawater temperature in the waters surrounding the plant exceeds 31 degrees Celsius, when water temperatures above 34 degrees Celsius are observed, or when water temperatures above 33 degrees Celsius persist for 12 hours. These numerical thresholds indicate that seawater temperature has been incorporated as a key variable in nuclear power plant operational risk management.

TEPCO says cooling interruption of spent fuel pool at Fukushima Daini Unit 1 due to human error

Tokyo Electric Power Company (TEPCO) announced on July 29 that the event in April 2026, where the spent fuel pool cooling system at Unit 1 of the Fukushima Daini Nuclear Power Plant was shut down for approximately 32 hours, was determined to be caused by human error. At the time of the incident, the plant was in the decommissioning phase. On April 5, a fault alarm was triggered by the cooling water circulation pump of Unit 1 at Fukushima Daini. After on-site personnel confirmed smoke from the equipment, the pump was stopped, resulting in an interruption of the spent fuel pool cooling system for about 32 hours. TEPCO previously stated that the cause was damage to the cable connecting the pump motor. According to TEPCO's latest explanation, the cable melting may be related to the installation method when the cable was replaced in 2012...
