Development and Qualification of Computer-Aided Assessments (CAS)
Abstract
Maximum utilization of computer-aided assessments (CAS) techniques and proper understanding of nuclear safety and reliability assessments can be achieved by the use of a program called GO . This document is a basic, yet substantive, qualification of the GO methodology and its computer software. Principal emphasis is placed on the event-tree concept upon which GO is based and on the use of the defined operator types (which represent components) to develop system models. The use of GO software to manipulate models and component data to generate the probabilities of occurrence of system events (reliability, safety, availability) is explained and exemplified. Seven sample systems are analyzed. A qualification of the fault finder and effect evaluation software is provided. The fault finder capability identifies component failures which singly or in confidence cause system failures. The effect evaluation capability develops confidence bounds on system estimates as a function of data uncertainties.
