Abstract

A nuclear power plant's maintenance program is the principal vehicle through which age-related degradation is managed. Over the past two years, the NRC (Nuclear Regulatory Commission) has evaluated the maintenance program of every nuclear power plant in the U.S. The reports issued on these in-depth team inspections have been reviewed to ascertain the strengths and weaknesses of the programs as related to the need to understand and manage the effects of aging on nuclear power plant systems, structures, and components. Selected results of this review are presented in this paper, including examples of inspection and monitoring techniques successfully used by utilities to detect degradation due to aging. Attributes of plant maintenance programs where the NRC inspectors felt that improvement was needed to properly address the aging issue are also discussed. 6 refs., 1 tab.

Managing aging in nuclear power plants: Insights from NRC maintenance team inspection reports

Technical Report Fresco, A ; Subudhi, M ; Gunther, W ; ...

A plant`s maintenance program is the principal vehicle through which age-related degradation is managed. From 1988 to 1991, the NRC evaluated the maintenance program of every nuclear power plant in the United States. Forty-four out of a total of 67 of the reports issued on these in-depth team inspections were reviewed for insights into the strengths and weaknesses of the programs as related to the need to understand and manage the effects of aging on nuclear plant systems, structures, and components. Relevant information was extracted from these inspection reports and sorted into several categories, including Specific Aging Insights, Preventive Maintenance,more »« less

Managing aging in nuclear power plants: Insights from NRC's maintenance team inspection reports

Journal Article Fresco, A ; Subudhi, M

Age-related degradation is managed through the maintenance program of a nuclear plant. From 1988 to 1991, the Nuclear Regulatory Commission (NRC) evaluated the maintenance program of every nuclear power plant in the United States. The authors reviewed 44 out of a total of 67 of the reports issued by the NRC on these in-depth team inspections. The reports were reviewed for insights into the strengths and weaknesses of the programs as related to the need to understand and manage the effects of aging on nuclear plant structures, systems, and components. The authors' conclusions are presented. 6 refs.
Maintenance team inspections

Conference Gody, A T ; McKenna, E ; Hart, K R - Transactions of the American Nuclear Society; (USA)

Good maintenance is a key factor in achieving and maintaining a high level of safety in plant operations throughout the life of a nuclear power plant. Thus, maintenance was chosen as the special area of emphasis in the Mandatory Team Inspection Program. This emphasis will continue throughout 1990 due to the increased interest in maintenance and the proposed rulemaking being considered by the US Nuclear Regulatory Commission (NRC). The paper discusses the maintenance team inspection program and its status, plant performance related to maintenance, management support of maintenance, and maintenance implementation.
