Equipments removal and renewal at Plutonium Conversion Development Facility. The Secondary removal and renewal program

The Plutonium Conversion Development Facility (PCDF) periodically carried out old equipment removal / renewal work for stable operation. The First removal / renewal program was carried out from 1993 to 1994. The Secondary removal / renewal of equipment (filter casings, microwave heating denitration apparatus, blender and glove boxes) was carried out from 1998 to 1999. Two new type air-line suits (double-layered type air-line suits and water flushing-decontamination-type air-line suits) were developed. These air-line suits were used for the Secondary removal / renewal program. The results of using these air-line suits the resistance test of the greenhouse against earthquakes and the contamination behavior of the glove box, which is independent from the ventilation system, are reported in this paper.
