Hokkaido Electric Power Co. said a worker died Tuesday night after falling into a gravel silo used to build a seawall while working on Unit 3 at the Tomari nuclear plant, the Hokkaido Shimbun reported. The company had planned to restart Unit 3 in mid‑December 2027. Hokkaido Electric said in July it was considering various restart scenarios; a company spokesman said it will "reconsider the restart date" after the accident investigation concludes. Tomari is Hokkaido’s only nuclear power station.
