Title: Evaluation of Loss of Offsite Power Events at Nuclear Power Plants: 1980 - 1996

It is recognized that the availability of AC power to commercial nuclear power plants is essential for safe operations and accident recovery. A loss of offsite power (LOSP) event, therefore, is considered an important contributor to total risk at nuclear power plants. In 1988, the U. S. Nuclear Regulatory Commission published NUREG-1032 to report on an evaluation of the risk from actual LOSP events that had occurred at nuclear power plants within the United States up through 1985. This paper summarizes a similar study, whose primary objective was to update the LOSP model parameters, frequency and recovery time, using power plant event data from 1980-1996, published as NUREG/CR-5496 in 1998. An additional objective of the study is to re-examine the engineering insights concerning LOSP events.
