Gas sampling type sodium small leak detector, SID (Sodium Ionization Detector), a gas sampling detector installed to monitor small sodium leak in the Prototype Fast Breeder Reactor Monju, had been operated since its system start-up test through to the 40% reactor’s output test. It’s use was terminated in April, 2018. SID showed some indication variations during its operation period, and necessary measures were implemented.
As a result, the SID system maintained its functions without any critical malfunction until the end of its operation.
