Nuclear reactor safety system
First Claim
1. A safety system for a nuclear reactor comprising:
- a series of transducers for measuring various different parameters of the nuclear reactor'"'"'s operation;
a series of parallel-connected computer-type look-up tables each individually connected to each one of the transducers, each look-up table containing a precalculated function of that parameter measured by said transducer connected to that look-up table indicative of percentage of full reactor load contributed by that parameter for a series of measured parameter values and outputing said precalculated function in response to the parameter signal measured by said transducer connected thereto;
a summing station for receiving all of the outputs of the respective computing stations and summing them up to establish a control signal indicative of percentage of allowable full power reactor operation.

Abstract
A safety system (10) for shutting down a nuclear reactor under overload conditions is provided using a series of parallel-connected computer memory type look-up tables (14a, 14b, 14c, 14d, 14e) each of which receives data on a particular reactor parameter (P, T, φT, φB, W) and each of which has stored therein a precalculated functional value [f(P); f(T); F(φT); f(φB); f(W)] for that parameter indicative of the percentage of maximum reactor load that the parameter contributes. The various functional values [f(P); f(T); f(φT); f(φB); f(W)] corresponding to the actual measured parameters are added together to provide a control signal (S) used to shut down the reactor under overload conditions.
