Japan's Nuclear Power Revival Enters Supply Chain Rebuilding Phase, with Spent Fuel and Engineering Capacity as Key Constraints

As Japan advances energy security, reduces dependence on fossil fuel imports, and expands low-carbon electricity supply, the focus of the country's nuclear power market is shifting from mere reactor restarts to a comprehensive supply chain rebuild covering manufacturing, operations and maintenance, life extension, fuel cycle, and waste management. GlobalData estimates Japan's nuclear power generation at 101.0 TWh in 2025 and projects it to increase to 123.3 TWh by 2035. Japan's policy target is to maintain nuclear power at approximately 20% to 22% of the electricity generation mix. Based on total annual electricity demand of approximately 1,050 TWh, a 20% nuclear share corresponds to about 210 TWh, while a 22% share corresponds to about 231 TWh. Compared with the 2025 nuclear generation figure of 101.0 TWh, the estimated gap is approximately 109 TWh to 130 TWh.

After only 4 days of restart, Unit 2 of France's Golfech Nuclear Power Plant shut down again due to Garonne River water temperature approaching limit

On the evening of August 8, French utility EDF (Électricité de France) once again shut down Unit 2 of the Golfech Nuclear Power Plant, just four days after the unit had been restarted. The direct cause of this shutdown was that the water temperature of the Garonne River was expected to reach 28°C on August 9, hitting the local operational limit. Since Unit 1 had already been taken offline for maintenance and fuel replacement, the closure of Unit 2 left both reactors at the Golfech plant simultaneously out of service, with the station temporarily ceasing power generation. Located in the Tarn-et-Garonne department of France, the Golfech Nuclear Power Plant was commissioned between 1991 and 1994, and features two 1,300 MW pressurized water reactor units. It draws cooling water from the Garonne River and dissipates heat through natural-draft cooling towers. According to EDF dat...
