The operation training simulator has been developed for the purpose of safety and stable operation in the Rokkasho reproce ssing plant, the first commercial spent nuclear fuel reprocessing plant in Japan. The simulator is designed to contribute t o the acquisition of the knowledge and skills indispensable for the plant operators and to the promotion of good team-work among operators. In this paper we present the outlines of the operator training simulator for Rokkasho reprocessing plant....

Inconel 600 alloy, Ni base alloy, and SUS304 steel, austenitic stainless steel, are used for steam generators tubing, pressure vessel, etc. due to its high strength and high corrosion resistance. Stress corrosion cracking is attributed to sensitization at grain boundary occurs and it causes failures in plants. Though these alloys are paramagnet, they transforms into ferromagnetic along grain boundaries when sensitization occurs. Therefore nondestructive evaluation using magnetic measurement for sensiti...
