POSSIBILITY OF IRRADIATING IN RUSSIAN REACTORS THE PLUTONIUM RECYCLED FROM MIXED URANIUM-PLUTONIUM FUEL FABRICATED IN MARCOULE (FRANCE)

摘要

EdF's idea of irradiating in Russian fast reactors fuel pins with recycled plutonium arose in February 2016 during a discussion with CEA of testing experimental FA in BN-600. EdF proposed to additionally irradiated several fuel pins fabricated using plutonium obtained after reprocessing of mixed fuel irradiated in PWR. In 2017, the studies with fabrication of full-scale FA were to expensive, so that proposals were developed for irradiating several tens of grams of UO2-PuO(2)in a laboratory facility in Atalante (CEA), using plutonium obtained during reprocessing of mixed fuel, as well as several ASTRID-type fuel pins in BN-600. The studies are to be conducted in three stages: small-scale irradiation in BOR-60, computational studies of the irradiation of 10 full-scale FA with recycled plutonium in BN-600, irradiation in BN-600 of one to five experimental ASTRID-type fuel pins with recycled plutonium. The technical problems of the specified experiments are discussed.
