Experimental nuclear reactor Joyo restart delayed

The operator of a suspended experimental fast reactor in Ibaraki, north of Tokyo, has decided to delay its restart currently set by March 2022.
The Joyo experimental fast nuclear reactor is expected to replace the prototype fast-breeder nuclear reactor, Monju, as part of the development of fast reactors in Japan.
The Japanese government decided to scrap the trouble-marred Monju last year.
The Japan Atomic Energy Agency in March submitted a request for the state to carry out a safety assessment of Joyo with the aim of restarting the reactor by March 2022.
The document stated that Joyo will run on 100,000 kilowatts despite its total output capacity of 140,000 kilowatts to accommodate a smaller-scale evacuation plan for nearby residents in case of an accident.
The Nuclear Regulation Authority delayed the inspection, and instead asked the operator to run on its total capacity.
The agency is considering reducing the amount of nuclear fuel inside the reactor to reduce output.
Officials say they will apply for government inspections next year.
They say the agency must still decide when it will put Joyo back online.
