Draft - Request for Additional Information from Fire Protection Branch RE: EPU ADAMSAccessionNumber:
ML100620202 Steve By letter to the U.S. Nuclear Regulatory Commission (NRC) dated April 7, 2009 (Agencywide Documents Access and Management System Accession No. ML091250564), FPL Energy Point Beach, LLC, submitted a request to increase each units licensed core power level from 1540 megawatts thermal (MWt) to 1800 MWt reactor core power, and revise the technical specifications to support operation at this increased core thermal power level.
The Fire Protection Branch has reviewed the information provided and determined that in order to complete its evaluation, additional information is required. We would like to discuss the questions, in draft form below, with you in a conference call.
This e-mail aims solely to prepare you and others for the proposed conference call. It does not convey a formal NRC staff position, and it does not formally request for additional information.

DRAFT Fire Protection RAI #5 Some plants credit aspects of their fire protection system for other than fire protection activities, e.g., utilizing the fire water pumps and water supply as backup cooling or inventory for nonprimary reactor systems. If the Point Beach Nuclear Plant (PBNP) Units I and 2, credits its fire protection system in this way, the EPU LAR should identify the specific situations and discuss to what extent, if any, the EPU affects these non-fire-protection aspects of the plant fire protection system. If the PBNP Units I and 2 do not take such credit, the NRC staff requests that the licensee verify this as well.
NextEra Response Non-fire suppression uses of the fire protection water supply for PBNP are:
Support of post-fire safe shutdown activities by providing a backup supply of bearing cooling water to the turbine-driven auxiliary feedwater pumps. This function is not changed by EPU.
Provide a backup source of make up water for evaporative cooling of the spent fuel pool in the event of loss of spent fuel pool cooling. The spent fuel pool make up requirement increases due to EPU, but remains well within the fire water local hose station flow capability.
Provide a backup supply of feedwater through the use of the diesel-driven fire pump and routing of a fire hose between existing connections on the fire header to the condensate storage tanks. This function is not affected by EPU because the fire protection system makeup capability is much greater than the AFW requirement.
Request:
Provide clarification how will the non-fire suppression use of fire protection water impact the need to meet the fire protection system design demands? Does fire suppression system water flow demands designed includes above three allowances?
