Optimization of Test Cases for Experimental Reliability Evaluation of Digital Reactor Protection System

Software reliability to evaluate the safety of digital I&C systems was assumed as extremely low or zero. The probability of Software Failure can be evaluated by two specific tests. This work is a part of the project to quantitatively evaluate the software reliability of digital RPS; Software Logic Exhaustive Test and Hardware-Software Integrated Test. This research offers experimental importance during the reliability evaluation to obtain approximate reliability with limited test cases. On the other word, test cases with low importance, which means that the test cases occur rarely, can be screened out according to the results of this research
