Abstract
This paper demonstrates a nuclear reactor safety monitor incorporating hard-wired, redundant, digital program modules that control independent, redundant, digital monitor modules. One monitor module is used for each parameter significant to reactor safety. The characteristics of a proposed LIQUID METAL FAST BREEDER REACTOR are used as the reference performance criteria. The established criterion that a single failure must not prevent reactor shut down is used as the failure mode criterion. Within the program module, a programmable read-only memory (PROM) is used for sequence control of another PROM containing variable length subroutines. The subroutine PROM outputs are used as photo-isolated logic outputs for sequence control of the various monitor modules. The program module action is modeled on a digital computer. A four-input digital monitor module is developed. This module provides a shut down signal if three of the inputs exceed the parameter limit.
