摘要：
PROBLEM TO BE SOLVED: To provide a radiation monitor which improves the
detection accuracy of the change in radiation doses caused by radionuclides flowing in main steam piping, and also to simplify the structure of the monitor.
SOLUTION: In the radiation monitor 1, a radiation detector 5, a preamplifier 7 and a signal processor 8 are connected in series via cables 6. Radiation dose rate indicators 9 an
16, radiation dose rate recorders 10 and 17, warning apparatuses 11 and 18 and a trip circuit 15 are connected to the signal processor 8 via the cables 6. The radiation monitor 1 functions as a main steam piping radiation monitor and a containment atmospheric monitoring system (CAMS). The radiation dose rate indicator 9, the radiation dose rate recorder 10 and the warning apparatus 11 are constituted as the CAMS. The trip circuit 15, the radiation dose rate indicator 16, the radiation dose rate recorder 17 and the warning apparatus 18 are constituted for the main steam piping radiation monitor. The radiation detector 5 is placed on the tip in a penetration 4 set up, inside a reactor containment vessel 19.
