On this page: Publication Information AbstractDownload complete document NUREG/CR-6424 (PDF - 15.42 MB)Publication Information **Manuscript Completed:** March 1996**Date Published:** March 1996 **Prepared by:** D.J. Naus, C.B. Oland, ORNL B.R. Ellingwood, JHU Oak Ridge National Laboratory Operated by Martin Marietta Energy Systems, Inc. Oak Ridge National Laboratory Oak Ridge, TN 37831 **Subcontractor:** Department of Civil Engineering The Johns Hopkins University 3400 North Charles Street Baltimore, MD 21218-2699 H.L. Graves, NRC Project Manager **Prepared for:** Division of Engineering Technology Office of Nuclear Regulatory Research U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 NRC Job Code B0845 Availability Notice Abstract The Structural Aging Program provides the United States Nuclear Regulatory Commission with potential structural safety issues and acceptance criteria for use in continued service assessments of nuclear power plant safety-related concrete structures. The program was organized under four task areas — Program Management, Materials Property Data Base, Structural Component Assessment/Repair Technology, and Quantitative Methodology for Continued Service Determinations. Under these tasks, over 90 papers and reports were prepared addressing pertinent aspects associated with aging management of nuclear power plant reinforced concrete structures. Contained in this report is a summary of program results in the form of information related to longevity of nuclear power plant reinforced concrete structures, a Structural Materials Information Center presenting data and information on the time variation of concrete materials under the influence of environmental stressors and aging factors, in-service inspection and condition assessments techniques, repair materials and methods, evaluation of nuclear power plant reinforced concrete structures, and a reliability-based methodology for current and future condition assessments. Recommendations for future activities are also provided.
