TECHNICAL EVALUATION REPORT EMERGENCY DIESEL GENERATOR TECHNICAL SPECIFICATIONS STUDY RESULTS
The purpose of this report is to review technical specifications for emergency diesel generators in the context of new information developed in the Nuclear Plant Aging Research Program and the application of current NRC regulatory concepts and knowledge. Aging and reliability relationships related to the standard technical specifications are reviewed and supported by data and published information to ensure that conservative and beneficial specifications are identified. Where technical specifications could adversely influence aging and reliability, the technical issues and reasonable alternatives are identified for consideration. This report documents and spans the technical progress from the published and approved regulatory documents to the current knowledge basis. This ensures that the technical bases for the technical specifications discussed are documented and relatively complete subject information is contained in one document. The Pacific Northwest Laboratory (PNL) has participated in the Nuclear Plant Aging Research (NPAR) Program directed by the Nuclear Regulatory Commission's (NRC) Office of Nuclear Regulatory Research, Division of Engineering. The NPAR study of emergency diesel generator aging was performed in two phases. In Phase I, plant operating experience, ~ata, expert opinion and statistical methods were used to produce a new data base related to aging, reliability, and operational readiness of nuclear service diesel generators. Phase II was chiefly concerned with aging mitigation measures.
