Spent fuel of Monju reactor to be reprocessed in France

The Japan Atomic Energy Agency plans to send the spent fuel of the Monju reactor for reprocessing to France. Assuming that the JAEA and Orano agree on the terms of the contract, the shipments will begin in 2034 and be completed in 2037.

The Monju reactor is a prototype fast-neutron reactor that was shut down in 2017. The 30-years decommissioning plan was approved in 2018.

According to one estimate, the Monju spent fuel contains about 2.1 tonnes of (reactor-grade) plutonium.
