ENCLOSURE REQUEST FOR ADDITIONAL INFORMATION RELATED TO FIRSTENERGY NUCLEAR OPERATING COMPANY (FENOC)
BEAVER VALLEY POWER STATION, UNIT NOS. 1 AND 2 (BVPS-1 AND 2)
EMERGENCY DIESEL GENERATOR (EDG)
ALLOWED OUTAGE TIME (AOT) EXTENSION DOCKET NOS. 50-334 AND 50-412 By letter dated May 26, 2004, as supplemented October 29 and December 3, 2004, and January 18, 2005, FENOC (the licensee), proposed changes to the BVPS-1 and 2 Technical Specifications. The proposed changes would extend the AOT from 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to 14 days to restore an inoperable EDG to operable status. In order for the Nuclear Regulatory Commission staff to proceed with its review of the proposed change, the following commitment is needed.
The present license amendment request proposes supplying the power needs of a blacked-out unit from the nonblacked-out unit. The proposal involves establishing this cross connection in 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and providing power for both units for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. In light of the recent operating experience that indicates increased duration on loss of offsite power, the proposed approach does not seem to provide for defense in depth measures to deal with an extended outage for an EDG. The approach to supply power to the blacked-out unit by rescheduling the safety system operation in the unaffected unit (disconnecting loads for short term on the unaffected unit to allow for the affected to unit to operate another load) is not acceptable because of the undue risk and operational complications imposed on the unaffected unit. NUMARC 87-00 Revision 1, addresses this concern in B-9 (page B-3) and in question 126 (pages I-25 and 26)
Provide details on what alternate onsite power source will be available for powering a blacked-out unit (because of the extended outage for one EDG) for the duration of the extended outage.
As discussed with your staff during February 3 and 10, 2005, conference calls, this should involve the submission of a formal commitment to provide an operable standby (capable of supplying load within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> of entering the EDG 14-day AOT) alternate alternating current power supply of sufficient capacity that it can be substituted for the inoperable EDG.
