Description
This facility was in the middle of the 1960 pilot plant to convert UF6 to sinterable UO2. In 1970 this plant after some modification was redesigned and provided for the conversion of UNH coming from LWR to UF6. At the end of 1985, 1300 t/U has been converted and delivered to enrichment plants. The reprocessed uranium from light water reactors is slightly enriched 0,9% to 2,25% and contains impurities. During the conversion process COMURHEX has to eliminate not only chemical but radiochemical impurities otherwise the material would never meet the specification for re-enrichment. In this paper the main impurities and decontamination effect of the COMURHEX process are discussed
