Additional monitoring is occasionally done on suspicious equipment such as pumps, motors, valves and so on, when monitoring parameters are dif ferent from normal operation in Nuclear Power Plant. To avoid excess radiation exposure during arrangements for the additional monitoring requ iring sensors installation and cables layout, wireless data transmission system is desired. ZigBee system, which uses 2.4GHz radio frequency a nd has repeating function, is suitable for the needs above without influencing on ...

The New Regulatory Requirements have been enforced since December, 2013. In the requirements, it is required that reprocessing plants should keep their performance-levels conforming to the standards set by the requirements. On the other hand, malfunctions of some equipment in the Rokkasho Reprocessing Plant which are required to maintain their performance-levels by the New Regulatory Requirements have been found after the enforcement of the requirements. These malfunctions are mainly due to the long-t...
