REACTOR OSCILLATION POWER RANGE MONITOR, REACTOR OSCILLATION POWER RANGE MONITORING METHOD, AND RECORDING MEDIUM CONTAINING REACTOR OSCILLATION POWER RANGE MONITORING PROGRAM |
摘要 |
According to one embodiment, a reactor oscillation power range monitor includes: a receiving unit configured to receive LPRM signals issued by LPRM detectors differing in vertical position out of a plurality of LPRM detectors placed in a reactor core; a specification unit configured to specify any exclusion signal which meets an exclusion condition out of the received LPRM signals; an estimation unit configured to estimate an alternative signal for the exclusion signal based on a regular signal which does not meet the exclusion condition out of the received LPRM signals; an arithmetic averaging unit configured to output an arithmetically averaged signal obtained by arithmetically averaging the regular signal and the alternative signal; a time averaging unit configured to output a time-averaged signal obtained by time-averaging the arithmetically averaged signal; and a calculation unit configured to output a standard value obtained by dividing the arithmetically averaged signal by the time-averaged signal. |
