Tokyo decided to permanently shut down unit in 2016 Monju, near the Tsuruga nuclear power station in Fukui Prefecture, western Japan, is a 246-MW sodium-cooled fast reactor. All the fuel assemblies at the Monju prototype fast breeder reactor (FBR), which is being decommissioned, have been transferred to a water-filled storage facility, the Japan Atomic Energy Agency (JAEA) said.

Fuel removal was planned to be completed by the end of 2022 and has ended on schedule, JAEA said.

When decommissioning of the plant began in 2018, 160 fuel assemblies were being stored within a sodium-filled storage tank, while 370 fuel assemblies remained within Monju's sodium-filled core.

JAEA began by removing the assemblies from the sodium-filled tank into the water-filled pond, then transferring assemblies from the core into the sodium-filled tank prior to being moved to the storage pond.
