German-based GNS (Gesellschaft für Nuklear-Service) said on 13 April that it had developed the CASTOR® geo26JP cask especially for the requirements of the Japanese market. The used fuel cask is designed for the storage and transport of up to 26 pressurised water reactor (PWR) fuel assemblies – the largest available capacity for fuel assemblies from the PWR nuclear power plants most widely used in Japan. It is based on the CASTOR® geo cask family for PWR and boiling water reactor (BWR) fuel assemblies of various designs, which was conceived to meet the needs of international customers for "high capacity casks" and is already in use in Belgium and Switzerland. Dr Linus Bettermann, Director of Sales at GNS said the CASTOR® geo26JP “offers the most efficient packaging solution for Japanese PWR fuel assemblies” because of its capacity and price.

Japan's Kansai Electric Power Co restarted unit 4 at its Takahama NPP in Fukui Prefecture.on 13 April after completing required upgrades to protect the plant against terrorist attacks and to fix system glitches, a spokeswoman said. Kansai Electric began powering up the 870 MWe reactor after dealing with upgrades, damage in the heat transfer tubes and regular maintenance and refuelling, she added. The reactor had been offline since October. Kansai Electric had restarted the 870MWeTakahama 3 unit in March, which had been shut since January 2020. Also in March, Kyushu Electric Power restarted the 1,180 MWe unit 4 reactor at its Genkai NPP in Saga Prefecture, which had been been shut for regular maintenance since Dec 2020.

The Japanese government on 13 April formally announced that the treated water stored at the Fukushima Daiichi NPP site will be discharged into the sea, “based on more than six years of comprehensive study by experts, reviews by the IAEA, and engagement with parties concerned”. Five disposal methods had earlier been considered by the government: controlled discharge into the sea, ground injection, discharge as steam, discharge as hydrogen, and solidification for underground burial.

The laboratory will be sited in granite 560m below ground in the Beishan region of Gansu province, in China’s remote northwest. China will spend $422m building an underground laboratory for research into storing high-level radioactive waste from the country’s growing fleet of nuclear power plants with the aim of building the country’s first deep geologic repository by 2050.

If successful, a repository that could store 100 years’ worth of high-level waste will be built, reports in China said. The waste will mostly be in the form of spent nuclear fuel, which is currently stored in spent fuel ponds at nuclear plant sites.

Reports said construction will begin next year and will finish by 2024. Work has begun on supporting infrastructure such as paved roads.

“We are doing research into this project and it will soon be put into practice,” said Liu Hua, head of the National Nuclear Safety Administration, during a press conference on Tuesday.

Tokyo Electric Power Co (Tepco) said on 7 April that it will accept a penalty imposed by the Nuclear Regulation Authority (NRA) over inadequate anti-terrorism measures at its Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture. This will prevent restart of the facility for at least a year. Tepco made the announcement in response to a decision by NRA in late March banniing it from moving any nuclear materials at unit 7 of the Kashiwazaki-Kariwa plant.

Introducing the 2020 report by Finnish company Fennovoima, CEO Joachim Specht said the Hanhikivi 1 project “is picking up speed and progressing well”. The Hanhikivi-1 project provides for the construction in Pyhajoki of a single-unit nuclear power plant based on a Russian-design VVER-1200 generation 3+ reactor. The project is currently at the stage of licensing and preparatory work is underway at the NPP construction site. A construction licence is expected in 2021. RAOS Project Oy is the general supplier under the EPC contract signed with Fennovoima on in 2013. RAOS Project, a 100% subsidiary of REIN JSC (part of Rosatom), was established in Finland in 2015 to implement the project.

BN-600 fast breeder reactor could operate until 2040 The turbine hall at the Beloyarsk-3 fast breeder nuclear plant in Russia. Courtesy Rosatom. The operator of the Beloyarsk-3 nuclear power plant in Sverdlovsk Oblast, central Russia, is planning to carry out work that could see the BN-600 fast breeder reactor unit operate for 60 years, the official Tass news agency reported.

According to Tass, specialists will replace 24 steam generator modules at the 560 -MW plant as part of a project to extend its service life until 2040. The unit began commercial operation in November 1981. Work will also include inspection of the reactor, turbine equipment and security systems.

In April 2020, Russia’s nuclear regulator Rostekhnadzor granted a licence for Beloyarsk-3 to operate until 2025. The BN-600 is the only fast breeder reactor that has operated for 40 years.

A second plant at the Beloyarsk site, the 820-MW BN-800 fast breeder reactor Beloyarsk-4, began commercial operation in October 2016.
