UNITED NUCLEAR REGULATORY WASHINGTON, D.C. 20555-0001 November 26, 2013 Mr. David A. Heacock President and Chief Nuclear Officer Virginia Electric and Power Company 5000 Dominion Boulevard Glen Allen, VA 23060-6711 NORTH ANNA POWER STATION, UNITS 1 AND 2: REQUEST FOR ADDITIONAL INFORMATION REGARDING FUKUSHIMA LESSONS LEARNED -FLOODING HAZARD REEVALUATION REPORT (TAC NOS. MF1106 AND MF11 07)
Dear Mr. Heacock:
By letter dated March 12, 2012, the Nuclear Regulatory Commission (NRC) issued a request for additional information (RAI) pursuant to Title 10 of the Code of Federal Regulations, Section 50.54(f) (hereafter referred to as the 50.54(f) letter). The request was issued as a part of implementing lessons-learned from the accident at the Fukushima Dai-ichi nuclear power plant. Enclosure 2 to the 50.54(f) letter requested licensees to perform a flood hazard reevaluation using present-day methodologies and guidance.
By letter dated March 11, 2013 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML 1307 4A925), Virginia Electric and Power Company (Licensee) submitted a response to Enclosure 2, Required Response 2 of the 50.54(f) letter. The NRC staff has determined that additional information is needed to complete its review. A response to the enclosed RAI is needed before the NRC staff can complete the review. This request was discussed with Mr. Tom Shaub of your staff on November 13, 2013, and it was agreed that licensee would respond within 30 days of the issuance of the draft RAI e-mail. The e-mail was sent on November 14, 2013. Should you have any questions, please me at 415-2597. .

Request for Additional Information cc w/encl: Distribution via Listserv INTERIM STAFF EVALUATION AND REQUEST FOR ADDITIONAL INFORMATION FUKUSHIMA LESSONS LEARNED FLOODING HAZARD REEVALUATION REPORT VIRGINIA ELECTRIC AND POWER COMPANY NORTH ANNA POWER STATION. UNITS 1 AND 2 DOCKET NOS. 50-338 AND 50-339 RAI No. 3.2-1, LI P The licensee is requested to provide high resolution, digital versions of Figures 2.1-1 2.1-4 as these figures are important in understanding the direction and boundary of RAI No. 3.2-2, LIP The licensee is requested to provide electronic versions of the input files used for and HEC-RAS modeling in the local intense precipitation RAI No. 3.2-3, LI P The licensee is requested to provide a description of the methods used to incorporate measurements and the magnitude of the elevation uncertainty in the local intense analyses.
Discuss the related uncertainty associated with the onsite flood level RAI No. 3.2-4, LIP The licensee is requested to discuss roof drainage features (e.g., scuppers, gutter outlets, for plant buildings, and how runoff from these drainage features are incorporated into the HMS modeling in the local intense precipitation flood RAI No. 3.2-5, LIP The licensee is requested to discuss how the vehicle barrier system was incorporated in HEC-HMS modeling in the local intense precipitation RAI No. 3.3-1, Stream and River The licensee is requested to provide electronic versions of the input files used for modeling in the flooding of rivers and streams RAI No. 3.4-1, Dam Failure Standard Review Plan Section 2.4.4 states: "If any onsite water control or storage exist above the site grade, failures of these from any cause should be determined and potential for flooding of SSC important to safety and doors and openings identified."
with this statement, staff requests the following information related to potential site Enclosure
-2 caused by a failure of the service water reservoir impoundment discussed in Section 2.3.4 of the licensee's FHRR: In Section 2.3.4 of the Flooding Hazard Reevaluation Report (FHRR), the licensee states that the service water reservoir dike is a "Seismic Class I structure, and has been evaluated to preclude overtopping, piping, slide and other sources of failure." The licensee is requested to describe the evaluation(s) performed for plausible failure causes (Le., hydrologic, seismic, and sunny-day failure modes) for the service water reservoir impoundment and, if applicable, provide an evaluation of subsequent site flooding using a hierarchical framework.
Specifically, the licensee is requested to provide evaluations of failure mechanisms consistent with using present-day guidance, methods, and data, including: evaluation of the potential for seismically-induced failure under site-specific seismic hazards defined using present-day guidance and methods, evaluation of the potential for hydrologically-induced failure (e.g., overtopping) under the local intense precipitation events applicable to the site, and evaluation of the potential for sunny-day failure. If crediting existing evaluations, the licensee is requested to provide justification that existing evaluations are consistent with present-day guidance, methods, and data or bounding of flood hazards that would result from an evaluation based on present day guidance, methods, and data. The licensee is requested to: (1) describe the models and assumptions that were used in the evaluations and (2) provide an explanation of the consistency of these evaluations with present-day guidance and methods as well as current data. If the consequences (i.e., floods) from any of these failure modes is judged not to affect the site, the license is requested to provide a justification for this conclusion, including a description of pertinent evaluations, models, and assumptions. Section 2.3.4 of the FHRR describes an emergency dike and intercepting trench capable of diverting water from a failure of the service water reservoir impoundment.
The licensee is requested to provide a detailed description of the site's topographic or flow division features, including maps showing their location.
In addition, the licensee is requested to provide an evaluation of the effectiveness of dike/trench systems (including the potential for erosion and sedimentation) following failure of the service water reservoir impoundment under the plausible failures modes. The licensee is requested to describe the models and assumptions that were used in the evaluations.
RAI No. 4.0-1, Integrated Assessment:
The March 12,2012, 50.54(f) letter, Enclosure 2, requests the licensee to perform an integrated assessment of the plant's response to the reevaluated hazard if the reevaluated floods hazard is not bounded by the current design basis. The licensee is requested to provide the applicable
-flood event duration parameters (see definition and Figure 6 of the Guidance for Performing an Integrated Assessment, JLD-ISG-2012-05) associated with mechanisms that trigger an Integrated Assessment.
This includes (as applicable) the warning time the site will have to prepare for the event, the period of time the site is inundated, and the period of time necessary for water to recede off the site for the mechanisms that are not bounded by the current design basis. The licensee is also requested to provide a basis for the flood event duration parameters.
The basis for warning time may include information from relevant forecasting methods (e.g., products from local, regional, or national weather forecasting centers).
