ABSTRACT As part of the Nuclear Plant Aging Research (NPAR) Program, the Pacific Northwest Laboratory is performing a Diesel Generator Aging Assessment Study for the U.S. Nuclear Regulatory Commission. In the on-going NPAR Phase II of the aging study, efforts have been focused on aging mitigation and other success strategies for improving nuclear plant diesel generator operation and maintenance. A study group of diesel experts, the authors of this report, met on April 29 and 30, 1987, to resolve issues on diesel generator aging mitigation and improved operations, testing and maintenance. This report documents the conclusions and recommendations of the study group. If these recommendations are put into practice, the experts agreed that many of the engine aging stressors could be either eliminated or their effects could be managed to reduce failures. The focus of the study group was to 1) address the diesel generator aging stressors resulting from the present nuclear industry testing practices, and 2) propose potential mitigating measures. A
