Power region monitor for reactor instrumentation system

Creators

Description

In an power region monitor for a reactor nuclear instrumentation system comprising local power region monitor (LPRM) units, average power region monitor (APRM) units and a rod block monitor (RBM) unit, each of the local power detected by each of LPRM units is inputted into the APRM units and the RBM unit in parallel. As a result, since each of the local power used when the RBM unit determines control rod withdrawal inhibiting signals is rapidly transmitted from each of the LPRM units to the RBM unit, a response time period from the detection of the local power in the reactor to the output of the control rod withdrawal signals can be shortened, thereby enabling to improve reactor safety. (N.H.)
