Radioactive materials in nuclear plants are confined in the facility at a negative pressure less than atmospheric pressure, which is maintained by the ventilation system. Therefore, it is important for nuclear safety to keep the negative pressure an d to monitor the condition of the ventilation system. Also, immediate maintenance is essential when the ventilation system fails. In the Tokai Reprocessing Plant, monitoring the negative pressure in the facilities and the condition of the ventilatio n system is...

Negative Pressure Monitoring and Maintenance Management of theVentilation System in the Tokai Reprocessing Plant

The Tokai Reprocessing Plant has recovered nuclear materials from spent nuclear fuel. Reprocessing process is consisted of shearing process, a dissolution process and an extraction process etc. Each facilities designed to confine radioactive materials in controlled area to keep negative pressure using ventilation system. This system has been used over 40 years. We analyzed influences to the trouble of aging equipment, and we considered necessary additional check out system to prevent troubles based on ...
