Japan’s Chugoku Electric Power Co announced that it will restart unit 2 at its Shimane NPP in the prefectural capital of Matsue in August 2024. This will be the first time the reactor has been operational in 12 years and seven months. The 820MWe boiling water reactor (BWR) will be the first BWR to be restarted since the accident at the Fukushima Daiichi NPP in 2011 where three BWR units suffered a core meltdown. Following the earthquake and tsunami which caused the accident, Japan closed all 54 of its nuclear power units and introduced more stringent safety requirements for their restart. Of the 33 currently considered to be operable, 10 have so far been restarted, all pressurised water reactors. In September 2021, Japan’s Nuclear Regulation Authority formally concluded that the reactor had passed safety review, a prerequisite for restarting. Shimane Prefecture Governor Tatsuya Maruyama agreed to the restart in June last year.

Swiss energy group BKW (formerly Bernische Kraftwerke) has completed defueling of the decommissioned Mühleberg NPP (KKM Kernkraftwerk Mühleberg). The 418 used fuel elements have all now been transferred to the interim storage facility in Würenlingen in northern Switzerland, reducing radioactivity by more than 99%. BKW noted that removal of the fuel was completed 16 months ahead of the original scheduled set in 2015.

The International Atomic Energy Agency (IAEA) is providing live data from Japan on the release of treated water from the Fukushima Daiichi NPP on the IAEA website. The data includes water flow rates, radiation monitoring data and the concentration of tritium after dilution. Fukushima NPP operator, Tokyo Electric Power Company (Tepco), has now begun the controlled discharge of the water into the sea. At the same time, Tepco began transmitting data from various points in the process to the IAEA.

Japan’s government has requested Tokyo Electric Power Company Holdings (Tepco) to promptly proceed with its preparations for the discharge into the sea of ALPS treated water stored at the Fukushima Daiichi NPP, according to a statement by International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi. This is in accordance with the implementation plan approved by Japan’s Nuclear Regulation Authority. “If there is no interference due to weather or sea conditions, the discharge into the sea is expected to start on 24 August,” IAEA noted.

Tokyo Electric Power Company (Tepco) announced it has begun releasing treated water currently stored at the damaged Fukushima Daiichi nuclear power plant into the ocean. The operation - expected to take up to 30 years to complete - is being closely monitored by the International Atomic Energy Agency (IAEA).
