概要
The nitric acid solution dissolving nuclear fuel material is transferred with the three way valve called VCV (VCV: vide-casse- vide in Fr.) using vacuum in the Tokai Reprocessing Plant. The initial VCV was not reliable because it had broken with in 1 or 2years. The cause of failure was damage of the plastic diaphragms in the moving parts. Then, the new VCV valve with stainless- steel bellows was developed. There is no failure in moving parts in 20years, therefore reliability is significantly improved.
