ABSTRACT

JRR-4 had been operated using HEU (93% enriched uranium) fuels since 1965. JRR-4 had consumed all HEU fuels and finished operation using them in January 1996. And JRR-4 modification works had started. The modification works, which were about fuel conversion, installation of a medical irradiation facility, repairing of the building and so on, had successfully completed in June 1998. JRR-4 achieved the first criticality using LEU (20% enriched uranium) fuel on July 141h, 1998 and begun performance tests. The result of performance test was fine and able to get a number of data. This paper presents the modification works and outline of performance tests.
