UNITED STATES "%..NUCLEAR REGULATORY COMMISSIONw WASHINGTON, D. C. 20555 GL-77-?' December 15, 1977All Power Reactor LicenseesThe demonstrated reliability of standby diesel generator (DG) unitsin operating nuclear power plants has been less than anticipated.The NRC has concluded that a systematic review and analysis of operatingproblems associated with diesel generator units is necessary to establishwhat practical measures may be taken to enhance the reliability of theseunits. The NRC, with the assistance of the University of Dayton, hasinitiated such a study. It is our intent that this study will providepractical results that will prove useful to each nuclear utility, there-fore, each operating reactor licensee is requested to respond to theenclosed questionnaire.An analysis will be performed on the information received and the resultsof this analysis, along with recommendations that mnay lead to improvedreliability, will be transmitted to licensees and applicants for theiruse. We believe that this information will assist in identifying aswell as avoiding or minimizing operating experiences encountered byothers. We view this effort as one of mutual interest.We ask that a single completed copy of the enclosed questionnaire bereturned to the Director of Nuclear Reactor Regulation, U. S. NuclearRegulatory Commission, Washington, D. C. 20555, by January 20, 1978.Please include on a separate sheet the name, address and phone numberof the person(s) at the reactor site responsible for completing thequestionnaire and responsible for responding to any follow-up communi-cations concerning the questionnaire or for arranging a reactor sitevisit.The responses to the majority of the questions can be answered with justa few words or by checking the appropriate space. In responding to thosequestions which do not apply to a particular installation and/or situation,please indicate ¶N/W' for "not applicable". If the question does apply toa particular installation or situation but the answer is not known, pleaseindicate "UN" for "unknown". For those entries on the questionnaire wherethe requested information is not known by January 20, 1978, please provideit in follow-up correspondence when it becomes available.I\
