The overall objective is to facilitate the cost-effective implementation of software-based I&C systems in nuclear power plants. This publication reports on the results of a Co-ordinated Research Project (CRP) and gives details of the experience gained in the areas of project management; requirements specifications; use of software explicitly tailored for nuclear applications, use of commercial-off-the-shelf (COTS) systems, generic pre-qualification of systems and components; safety/reliability enhancements; verification and validation; and licensing impact.
