Dear Sir or Madam:
By letter dated November 11, 2013, Entergy Operations, Inc., proposed changes to the Waterford Steam Electric Station, Unit 3 Updated Final Safety Analysis Report, which would clarify how the Pressurizer Heaters function is met for natural circulation at the onset of a loss of offsite power concurrent with the specific single point vulnerability.
After reviewing your request, the U.S. Nuclear Regulatory Commission staff has determined that additional information is required to complete the review. Please provide additional information requested in the enclosure w1thin 45 days of receipt of this letter.
If you have any questions, please contact me at 301-415-1445 or via e-mail at alan.wang@.nrc.gov.

REQUEST FOR ADDITIONAL INFORMATION LICENSE AMENDMENT REQUEST TO CLARIFY THE UPDATED FINAL SAFETY ANALYSIS REPORT PRESSURIZER HEATERS FUNCTION ENTERGY OPERATIONS, INC.
WATERFORD STEAM ELECTRIC STATION, UNIT 3 DOCKET NO. 50-382 By letter dated November 11, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML13316C052), Entergy Operations, Inc. (the licensee), submitted a license amendment request (LAR) in which it requested a revision to the Updated Final Safety Analysis Report (UFSAR) for the Waterford Steam Electric Station, Unit 3 (WF3). The proposed change would modify UFSAR Sections 1.9.26 and 5.4.10.2, to clarify how the Pressurizer Heaters function is met for natural circulation at the onset of a loss of offsite power concurrent with the specific single point vulnerability. The following question was developed as a result of the U.S. Nuclear Regulatory Commission (NRC) staff's review of the licensee's LAR.
- 1.
In Attachment 2 on page 4 of 6 and page 6 of 6, the licensee proposed to add, in part, the following clarification to UFSAR Section 5.4.1 0.2, "System Description" (Insert 2A and Insert 3):
The natural circulation coo/down analysis, performed to comply with Branch Technical Position 5-4, Design Requirements of the Residual Heat Removal System, does not credit the operation of any pressurizer heaters.
However, this analysis is not cited to a prior document submitted under a previous LAR and, therefore, it is not available to the NRC staff for consideration as part of the licensee's current request.
Since the WF3 UFSAR reflects the plant's specific design basis, please provide documentation that demonstrates NRC approval of the natural circulation cooldown analysis performed to comply with Branch Technical Position 5-4.
Please update the submittal to include this documentation as a reference citation.
