Title: NPAR- products, applications and closure

Abstract

Almost a decade ago the Office of Nuclear Regulatory Research (RES) developed and implemented a comprehensive research program (NUREG-1144) widely known as NPAR or Nuclear Plant Aging Research. The NPAR program is a structured research program specifically oriented to understanding significant age-related degradation mechanisms and their long term effects on properties and performance of important components and systems and ways to mitigate detrimental effects of aging. It provided a road map and a phased approach to research that is applicable to any structure, system, or component of interest. This hardware-oriented engineering research program led the industry worldwide and communicated a need to understand and manage age-related degradation effects in selected but important structures and components. At the conclusion (1995) of the NPAR program, 22 electrical and mechanical components, 13 safety-related systems, and 10 special topics will have been studied and results summarized in 160 technical reports. This reference library of information listed and summarized in NUREG-1377, Rev. No. 4 provides a foundation upon which individual programs can be built for the specific needs of a utility, a regulator, or equipment manufacturers. During the life of the NPAR program, it has provided technical bases and support for license renewal, codes andmore » standards, resolution of generic safety issues, information notices, regulatory guides and the standard Review Plan, as well as the Office of Nuclear Reactor Regulation and The NRC Regions. All ongoing NPAR activities will either be completed or terminated by the end of 1995. No new initiative will be undertaken. This paper summarizes NPAR products and accomplishments, application of the research results, and its status and closure.« less
