Annual report on operation and management of Hot Laboratories and Facilities; From April 1, 2006 to March 31, 2007

Sampei, Shinichi; Department of Hot Laboratories and Facilities

This is an annual report in a fiscal year 2006 that describes activities of the RFEF, the WASTEF, the RHL and the other research hot facilities in the Department of Hot laboratories and facilities. In RFEF, destructive examinations of BWR fuel rods and re-assembly were carried out as PIEs for a fuel assembly irradiated for 5 cycles. Mechanical property measurement of high burn-up fuel rods were performed as spent fuel integrity test for long term dry storage. In WASTEF, SSRT and UCLT of in-core materials in pressurized high-temperature water condition, SCC tests for high-performance fuel cladding material and calorific value measurement of pulse irradiated fuel in NSRR were carried out. In RHL, equipment un-installations and decontamination were performed to lead cells. And modification of fuel storage room were started in order to utilize the facility for un-irradiated fuel storage. In addition, management of the other research hot facilities were carried out.
