Survey and assessment of conventional software verification and validation techniques

Reliable software is required for nuclear power plant applications. Verification and validation (V ampersand V) techniques may be applied during software development to help eliminate errors that can inhibit the proper operation of digital systems and that may cause safety problems. EPRI and the NRC are cosponsoring this investigation to determine the best strategies for V ampersand V of expert system software. The strategy used for a particular system will depend on the complexity of the software and the level of integrity required. This report covers the first task in the investigation of reviewing methods for V ampersand V of conventional software systems and evaluating them for use with expert systems
