Docket Nos.
License Nos.96-516 R2 50-280 50-281 50-338 50-339 DPR-32 DPR-37 NPF-4 NPF-7 NRC GENERIC LETTER 96-06 ASSURANCE OF EQUIPMENT OPERABILITY AND CONTAINMENT INTEGRITY DURING DESIGN-BASIS ACCIDENT CONDITIONS On September 30, 1996, the Nuclear Regulatory Commission issued NRC Generic Letter 96-06, "Assurance of Equipment Operability and Containment Integrity During Design-Basis Accident Conditions." The generic letter requested that licensees determine: (1) if containment air cooler cooling water systems are susceptible to either waterhammer or two-phase flow conditions during postulated accident conditions, and (2) if piping systems that penetrate the containment are susceptible to thermal expansion of fluid so that overpressurization of piping could occur.
The generic letter requires two written responses. First, within 30 days of the issuance of the generic letter, a written response is required to confirm whether the requested actions, information and schedule identified in the generic letter will be completed. Second, within 120 days of the generic letter, a written summary report is to be submitted describing the actions taken and conclusions reached relative to susceptibility for waterhammer and two-phase flow in the containment air cooler cooling water system as well as for overpressurization of piping that penetrates containment. The summary report is also to include the basis for continued operability of affected systems and components as I/
applicable and the corrective actions that are planned to be implemented.
