SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at North Anna Power Station, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.
List of Findings and Violations
No findings or violations of more than minor significance were identified.
Additional Tracking Items
None.
PLANT STATUS
Unit 1 began the inspection period at approximately 10 percent power for a power escalation following a planned refueling outage. On October 4th, 2019, Unit 1 achieved rated thermal power and remained at or near rated thermal power for the remainder of the inspection period.
Unit 2 operated at or near rated thermal power for the entire inspection period.
INSPECTION SCOPES
Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed plant status activities described in IMC 2515, Appendix D, Plant Status, and conducted routine reviews using IP 71152, Problem Identification and Resolution. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

INSPECTION RESULTS
Observation: Unit 1 and Unit 2 Common Cause Failure of Auxiliary Feedwater Pump Discharge due to Tornado Missile 71152 The inspectors conducted a detailed review of the licensees evaluation of Regulatory Issue Summary (RIS) 2015-06, Tornado Missile Protection with respect to a design basis tornado missile that could impact all three trains of auxiliary feedwater pump discharge pipe and results in a previously unidentified common cause failure scenario. The issue is documented for Unit 1 in CR1124894, with prompt operability determination CA7621480, and for Unit 2 in CR1124899, with prompt operability determination CA7621494. The 12-inch diameter design basis missile enters the auxiliary feedwater pump house through the vestibule, maintains the line-of-sight trajectory and orientation through the existing barriers, and strikes all three trains of auxiliary feedwater pump discharge pipe. The licensees UFSAR identifies that the auxiliary feedwater pumphouse is protected from tornado missiles. The acceptable design parameters for a tornado resistant structure are:
- A 2-foot-thick heavily reinforced concrete with rebar (from the licensees UFSAR)
- A 2-inch-thick steel plate (from Calculation CE-1856, Design Supplemental Missile Barrier for Aux. Feedwater Pump House, dated July 14, 2006)
For Unit 1, the licensees operability determination identifies the tornado missile would pass through 24 inches of non-reinforced concrete from the nearby structure and 1.2 inches of the metal equipment and support structures in the auxiliary feedwater pumphouse. For Unit 2, the licensees operability determination also relies on the metal equipment and support structures totaling over 2.5 inches of metal within the auxiliary feedwater pumphouse
Following Enforcement Guidance Memorandum 15-002, Enforcement Discretion for Tornado-Generated Missile Protection Noncompliance, the licensee reviewed RIS 2015-06, concluded that a technical specification controlled structure does not comply with the current licensing basis, performed an engineering evaluation to determine the structure is operable but non-conforming, and is addressing the non-complying condition through their corrective action program.
Observation: Containment Equipment Hatch Closure Requirements 71152 The inspectors conducted a detailed review of an NRC-identified issue in CR 1130343, initiated on September 8, 2019, regarding the uncertainty involved in how many personnel would be available to assist during a postulated required containment hatch closure.
During this inspection, the resident inspectors discovered that one of the emergency operating procedures that could require a hatch closure, 1-AP-11, Loss of RHR, Revision 34, required operators to announce a containment evacuation prior to directing the hatch closure team on station to close the hatch, which by procedure is required to be closed within the time to boil or within 45 minutes, whichever is lower. However, the residents discovered that when performing hatch closure drills, non-assigned personnel would assist the team in closing the hatch. Since an evacuation was ordered prior to a hatch closure order, the licensee and the resident inspectors agreed that the closure team should not rely on outside assistance. The licensee directed the hatch closure team to expect to do any future drill or actual required closure without assistance. The licensee enhanced their process to ensure that future drills would be more accurate to real scenarios. Additionally, based on the sites self-imposed standards and alternate source term documentation, there are no requirements related to how quickly the hatch must be secured, so there are no performance deficiencies associated with this inspection.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
- On January 8, 2020, the inspectors presented the integrated inspection results to Ms.
Lisa Hilbert and other members of the licensee staff.
