Abstract:

A method of determining the probability of successful operation of a nuclear power generating station for any minimum acceptable fraction of a given operating cycle is described. A digital computer program is provided to carry out the required calculation and automatically indicate the return to be expected from improved reliability and redundancy in the weakest component. Sample calculations for EBWR and PM-1 are presented to illustrate the use of the method. It is shown that to increase the accuracy of these probability calculations better reliability data are required, in particular on components specifically designed for inclusion in nuclear power plants. To overcome this difficulty, a proposed reliability data gathering procedure is presented. The procedure is based upon the use of punched cards to facilitate data handling. An additional computer program is provided to accept component failure, repair data, and plant operating history, and to produce failure rate and average repair time information. Author
