Direct digital control of the Gentilly Nuclear Power Station
From national topical meetlng on mathematical models and computational techniques for analysis of nuclear systems; Ann Arbor, Michigan, USA (8 Apr 1973). In mathematical models and computational techniques for analysis of nuclear systems. The main features of the control room are shown. A general view of the main control panel and the operator's console is presented. The CRT graphic display unit at the side of the operator's console and the CRT message displays and the fueling machine console are shown. The key part of the overall station control system is the control computer system, which consists of dual SEL 810A digital computers together with the peripheral equipment. Plant signals go to both computers in parallel. Either computer is capable of controlling, and the other is on standby. Each computer has a watchdog circuit that times out'' in two seconds unless it is held up by the successful completion of a set of self- check routines. If either computer detects a fault, its watchdog drops out, and this transfers control to the other computer. Transient faults result in one or more automatic restarts, provided this can be done before the watchdog drops. The programs are executed in both the operating and standby computers, but the outputs of the standby computer are inhibited. If both computer watchdogs drop, external loglc shuts the plant down without invoking the protective system. The positive power coefficient is exploited, in this case, to achieve a rapid shutdown with a relatively small negative control reactivity. (auth)
