Subject:
Response to NRC Request for Additional Information Concerning Generic Letter 96-06, "Assurance of Equipment Operability and Containment Integrity During Design-Basis Accident Conditions" (TAC No. M96803)
Ladies and Gentlemen:
This letter transmits a FirstEnergy Nuclear Operating Company (FENOC) response to a Nuclear Regulatory Commission (NRC) Request for Additional Information (RAI) related to the Davis-Besse Nuclear Power Station, Unit 1 (DBNPS) response to Generic Letter (GL) 96-06, "Assurance of Equipment Operability and Containment Integrity During Design-Basis Accident Conditions." GL 96-06, issued by the NRC on September 30, 1996, requested, in part, that licensees evaluate their cooling water systems that serve containment air coolers to assure that they are not vulnerable to waterhammer and two-phase flow conditions.
By letter dated November 20, 2003, (letter Log Number 6137), the NRC staff requested that FENOC respond to three observations with regard to the DBNPS responses to GL 96-06.
Additionally, because FENOC has modified the DBNPS cooling water piping to the containment air coolers, the NRC staff requested that FENOC review the DBNPS responses to GL 96-06 and supplement them where appropriate. Although the NRC staff has also concluded that the DBNPS response to the two-phase flow issue was acceptable, due to recent piping modifications the NRC staff requested that FENOC either affirm that the DBNPS responses are still valid in this area or supplement the responses for two-phase flow. The NRC requested that FENOC respond within 45 days of the date of the letter with a schedule for responding to these requests.
The updated responses requested in the NRC's RAI are dependent upon activities to be performed during 14RFO; therefore, FENOC will provide the requested responses within 90 days following the completion of 14RFO. FENOC will promptly notify the NRC of any change in schedule if additional time is necessary to provide a complete response.
