Chloroprene rubber gaskets are often used to seal the glove box body and its panels. Such gaskets are deformed with compressive pressure and its elastic restoring force keeps sealing property. Therefore, gaskets play an important role in glove box sealing. However, physical properties of those used in glove box have not reported so far. In this study, hardness, elongation, tensile strength and compression set are investigated and its sealing performances are evaluated. The gaskets samples are taken fro...

Physical property of seal-gasket for glove box panel in reprocessing facilities

Test equipment,containers,and analytical wastes,generated by experiments using spent fuel pieces in hot cell of Operation Testing Laboratory and by analysis of highly active liquid wastes in hot analytical cell line of Tokai Reprocessing Plant,are treated as highly radioactive solid wastes.These wastes are stored in specific shielded containers called waste cask and then transport to the storage facility.The treatment of these highly radioactive solid wastes have been carried out for 40 years with upgrading...

Treatment technology of highly radioactive solid waste generated by experimental tests and sample analysis in reprocessing facilities

Radioactive liquid waste from the Tokai Reprocessing Facility Analytical Laboratory is temporarily stored in intermediate waste storage tanks by using receiving valves. Then, the liquid waste is transferred to liquid treatment facility by using liquid feed valves. The deterioration of the gasket part of these valves (leakage of waste liquid) was confirmed in 2004. Since then, the material of gaskets was changed from polyethylene to polytetrafluoroethylene(PTFE). In 2016, the gaskets were replaced by periodi...
