LAR to Revise Staff Augmentation Times for ERO (TAC Nos. MF32.docx
Dear Ms. Gunderson:
By letter dated December 20, 2013, Northern States Power Company, a Minnesota corporation, doing business as Xcel Energy (NSPM, the licensee), submitted a license amendment request for Prairie Island Nuclear Generating Plant (PINGP), Units 1 and 2. NSPM submitted a supplemental letter dated October 15, 2014, in response to U.S. Nuclear Regulatory Commission (NRC) staff requests for additional information (RAIs). The proposed amendment would revise the PINGP Emergency Plan to increase staff augmentation response times for certain Emergency Response Organization positions from 30 and 60 minutes to 90 minutes.
The NRC staff has reviewed the aforementioned information provided by NSPM and determined that additional information is needed to complete its review. An e-mail was provided to NSPM on March 20, 2015, transmitting draft supplemental requests for additional information (RAIs). The draft supplemental RAIs were discussed in a teleconference between NSPM and the NRC staff on May 7, 2015. As a result of the teleconference, the draft supplemental RAIs were modified and are being provided as an attachment to this e-mail.
You may accept the draft supplemental RAIs as formal requests for additional information and provide a response by May 29, 2015. Alternatively, you may request to discuss the contents of the draft supplemental RAIs with the NRC staff in a conference call, including any change to the proposed response date.
Please dont hesitate to contact me if you have any additional questions or concerns.
Sincerely, TERRY A.

1 SUPPLEMENTAL DRAFT REQUESTS FOR ADDITIONAL INFORMATION PRAIRIE ISLAND NUCLEAR GENERATING PLANT, UNITS 1 AND 2 LICENSE AMENDMENT REQUEST TO REVISE STAFF AUGMENTATION TIMES IN THE EMERGENCY PLAN DOCKET NOS. 50-282 AND 50-306 (TAC NOS.MF3280 AND MF3281)
By application dated December 20, 2013 (Reference 1), as supplemented by letter dated October 15, 2014 (Reference 2), Northern States Power Company, a Minnesota corporation doing business as Xcel Energy (NSPM), requested an amendment to the Prairie Island Nuclear Generating Plant (PINGP), Units 1 and 2, Site Emergency Plan (PISEP). NSPM requested review and approval of a revision to the PISEP to increase staff augmentation times for certain emergency response organization (ERO) positions from 30 or 60 minutes to 90 minutes.
The following requests for additional information (RAIs) are necessary to facilitate thetechnical evaluation being conducted by the NRC staff in the OperatingReactor Licensing and Outreach Branch, Division of Preparedness and Response, in the Office of Nuclear Security and Incident Response. The draft RAIs are based upon information provided in the NSPMapplication dated December 20, 2013 (Reference 1), as supplemented by letter dated October 15, 2014 (Reference 2). Timely and accurate response to these draft RAIs is requested.
General Discussion NUREG-0654/FEMA-REP-1 (Reference 3) provides guidance for on-shift staffing and timely augmentation. On-shift staffing is required to be evaluated by Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Appendix E.IV.A.9. Generally, licensees used Nuclear Energy Institute (NEI) document 10-05, Assessment of On-Shift Emergency Response Organization Staffing and Capabilities, Revision 0 (Reference 4), and NRC Interim Staff Guidance (ISG) document NSIR/DPR-ISG-01, Emergency Planning for Nuclear Power Plants (Reference 5), to perform these reviews. NSIR/DPR-ISG-01provides a series of events that are to be used in the analysis to demonstrate that on-shift personnel assigned emergency plan implementation functions are not assigned responsibilities that would prevent the timely performance of their assigned functions as specified in the emergency plan.
The guidance for timely augmentation of on-shift staffing continues to be Table B-1 of NUREG-0654/FEMA-REP-1(Reference 3), whichstates under the planning basis that no single specificaccident sequence should be isolated as the one for which toplan because each accident could have different consequences,both in nature and degree. Further, the range of possibleselection for a planning basis is very large, starting witha zero point of requiring no planning at all because significantoffsite radiological accident consequences are unlikely to occur,to planning for the worst possible accident, regardless ofits extremely low likelihood.
Licensees may submit alternatives to this guidance for NRC staff review and approval;however, the staff must reach a reasonable assurance finding in accordance with 10 CFR
2 50.47(a)(1)(i),as well as meeting 10 CFR 50.47(b)(2) and the applicable requirements of AppendixEto10 CFR Part 50.
By application dated December 20, 2013 (Reference 1), as supplemented by letter dated October 15, 2014 (Reference 2), NSPM stated why augmentation was not required for 90 minutes following event declaration for specific accident scenarios. However, as part of the response to the RAIs listed below, the NRC staff requests NSPM to clearly explain how augmentation capability, as defined in Table B-1, is maintained.
