Zaporizhzhia Nuclear Power Plant Briefly Loses External Power, Restored via 330 kV Line

The International Atomic Energy Agency (IAEA) reported on August 4 that the Zaporizhzhia Nuclear Power Plant briefly lost external power supply that day. This marked the 24th occurrence of external power interruption at the plant since the outbreak of the related conflict. According to the report, the plant lost connection with the Ferrosplavnaya-1 transmission line, currently the only one still in service, in the afternoon, and emergency diesel generators provided backup power thereafter. The IAEA stated that the cause of the incident remains unclear. The plant management said the brief external power interruption was related to a technical fault in the automatic control system, and power supply was restored in less than an hour. Currently, the plant's auxiliary power is supplied by the 330 kV Fer...

Finland's Olkiluoto Spent Nuclear Fuel Final Disposal Facility Passes Regulatory Safety Assessment

The Radiation and Nuclear Safety Authority of Finland (STUK) released a safety assessment report on August 4, concluding that Posiva's spent nuclear fuel encapsulation plant and final disposal facility at Olkiluoto, Finland, meets the safety requirements for an operating license. This conclusion brings the project, regarded as the world's first industrial-scale geological final disposal facility for spent nuclear fuel, one step closer to obtaining government approval for operation. The facility is located on Olkiluoto Island in the municipality of Eurajoki, southwestern Finland, and is designed to dispose of spent nuclear fuel generated by the Olkiluoto nuclear power plant units of Teollisuuden Voima Oyj (TVO) and the Loviisa nuclear power plant units of Fortum. Posiva submitted its operating license application in December 2021...

Russian Nuclear-Powered Icebreaker "Yakutia" Provides First Escort for Luxury Cruise Ship to Wrangel Island Nature Reserve

This summer, the second group of tourists to Wrangel Island successfully landed on the nature reserve. 150 tourists were able to witness with their own eyes this mysterious island known as the "birthplace of polar bears." This was made possible thanks to the nuclear-powered icebreaker Yakutia providing ice escort services for the luxury cruise ship SH Minerva, ensuring navigational safety. This year, ice conditions in the Chukotka region were relatively complex, posing challenges to the cruise ship's operations. Previously, SH Minerva had failed to reach Wrangel Island due to its inability to break through sea ice, so the trip organizers took special measures this time. RussiaDiscovery and Vodokhod companies submitted a request to Rosatomflot...
