High Pressure Coolant Injection (HPCI) system risk-based inspection guide for Dresden Nuclear Power Stateion, Units 2 and 3

A review of the operating experience for the High Pressure Coolant Injection (HPCI) system at the Dresden Nuclear Power Station Units 2 and 3 is described in this report. The information for this review was obtained from Dresden Licensee Event Reports (LERs) that were generated between 1980 and 1989. These LERs have been categorized into 23 failure modes that have been prioritized based on probabilistic risk assessment considerations. In addition, the results of the Dresden operating experience review have been compared with the results of a similar, industry wide operating experience review. This comparison provides an indication of areas in the Dresden HPCI system that should be given increased attention in the prioritization of inspection resources.
