USNRC letter to Entergy Nuclear Operations, Inc., Request for Additional Information (RAI) Regarding Amendment Application to Revise Technical Specifications on DC Electrical System Requirements, dated October 27, 2005 (TAC No. MC7204).
Dear Sir:
By letter dated April 27, 2005 (Reference 1), Entergy Nuclear Operations, Inc. (ENO) proposed to amend the Technical Specifications (TS) for the James A. FitzPatrick Nuclear Power Plant (JAFNPP) by revising TS 3.8.4, 3.8.5 and 3.8.6, all of which deal with the DC electrical system.
These changes are based on TS Task Force (TSTF) Change Traveler TSTF-360 (Revision 1) that has been approved generically for the boiling water reactor (BWR) Standard TS, NUREG-1433 (BWR/4).
ENO received a request for additional information (RAI) from the NRC (Reference 2). to this letter provides the response to the RAI questions and Attachment 2 to this letter identifies a new commitment.
This response does not change the scope or conclusions in the original application, nor does it change the No Significant Hazards Consideration.
Should you have any questions or comments concerning this submittal, please contact Mr.
James Costedio at (315) 349-6358.

Attachment I to JAFP-05-0179 Entergy Nuclear Operations, Inc. - FitzPatrick Docket No. 50-333 Response to Request for Additional Information (RAI)
RAI 1
"Regarding your request to extend the battery charger allowed outage time (AOT)
(limiting condition for operation (LCO) 3.8.4 Required ACTION A.3) to 7 days. The proposed TSs Bases for this Required ACTION state the following:
Required Action A.3 limits the restoration time for the inoperable battery charger to 7 days. This action is applicable if an alternate means of restoring battery terminal voltage to greater than or equal to the minimum established float voltage has been used (e.g., balance of plant non-Class I E battery charger). The 7 day Completion Time reflects a reasonable time to effect restoration of the qualified battery charger to Operable status.
Describe the 'altemate means' that Entergy is crediting for this extended AOT.
Additionally, the NRC staff needs to be assured that this 'alternate means' for restoring battery terminal voltage to greater than or equal to the minimum established float voltage is supported by a back-up Class 1 E or non-Class 1 E power source (e.g., Class 1 E diesel generator). Furthermore, the 'alternate means' will need to be addressed in the JAFNPP Updated Final Safety Analysis Report since it would be credited for the 7-day AOT allowance.
The NRC staff's concern relates to a loss of offsite power or station blackout event.
Without an 'alternate means' that is capable of being supplied by a Class I E or non-Class 1 E back-up power source, the affected train's battery capacity could drain to the point where the battery may not have sufficient remaining capacity to operate the supply breakers to restore power to the 4160 V safety-related buses."
RESPONSE
Entergy is crediting the use of an appropriately sized temporary battery charger for the extended AOT. As stated in the No Significant Hazards Consideration in the proposed Technical Specification amendment, the temporary battery charger will be powered by Class 1 E power.
This 'alternate means' will be described in the Updated Final Safety Analysis Report (UFSAR) as committed to in Attachment 2 of this letter.
