SUBJECT:

SHEARON HARRIS NUCLEAR POWER PLANT - NRC INTEGRATED INSPECTION REPORT 05000400/2018004 AND EXERCISE OF ENFORCEMENT DISCRETION

Dear Ms. Hamilton:

On December 31, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Shearon Harris Nuclear Power Plant, Unit 1. On January 9, 2019, and January 23, 2019, the NRC inspectors discussed the results of this inspection with you and other members of your staff. The results of this inspection are documented in the enclosed report.

No NRC-identified or self-revealing findings were identified during this inspection. However, inspectors documented a licensee-identified violation which was determined to be of very low safety significance in this report. The NRC is treating this violation as a non-cited violation (NCV) consistent with Section 2.3.2.a of the Enforcement Policy.

In addition, a finding and an associated violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, was identified related to the licensees failure to protect components associated with the A Emergency Diesel Generator and Main Steam Safety Relief Valves from damage resulting from a potential tornado-generated missile in accordance with the plants licensing basis. Because this finding and violation was identified during the discretion period covered by Enforcement Guidance Memorandum 15-002, Revision 1, Enforcement Discretion for Tornado-Generated Missile Protection Non-Compliance, (Agencywide Documents Access and Management System Accession Number ML16355A286) and because the licensee was implementing compensatory measures, the NRC is exercising enforcement discretion by not issuing an enforcement action and is allowing continued reactor operation.

If you contest the violation or significance of the NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement; and the NRC resident inspector at the Shearon Harris Nuclear Power Plant. This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely,

/RA/

INSPECTION RESULTS

Licensee Identified Non-Cited Violation

71152 - Annual Follow-up of Selected Issues

This violation of very low safety significance was identified by the licensee and has been entered into the licensee corrective action program and is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Violation: Technical Specification (TS) 6.8.1.a required, in part, that written procedures be established, implemented, and maintained covering activities referenced in Regulatory Guide 1.33, Revision 2, dated February 1978, Appendix A, Section 8.b, which included procedures for TS surveillance testing.

Contrary to the above, from October 5, 2016, to July 26, 2018, the licensee failed to establish adequate surveillance test procedures, i.e., Maintenance Surveillance Test (MST)-I0080, Reactor Coolant System Wide Range Pressure (P-0402) Calibration, and MST-I0081, Reactor Coolant System Wide Range Pressure (P-0403) Calibration. These procedures test the interlocks for isolation valves used in the residual heat removal system to isolate the suction source from the reactor coolant system as required by TS Surveillance Requirement 4.5.2.d. The testing sequence in both MST procedures rendered a single train of high head safety injection inoperable by injecting a test signal in place of a pressure transmitter that measures reactor coolant system pressure. Additionally, an isolation valve from the refueling water storage tank was shut, making the opposite train of low head safety injection inoperable, causing both subsystems of the emergency core cooling system (ECCS)to be inoperable while in Mode 1. For each test, both subsystems of ECCS were inoperable for less than one hour.

Significance: The inspectors assessed the significance of the finding using IMC 0609, Appendix A, SDP for Findings at-Power, dated June 19, 2012. The finding was screened by Exhibit 2, Mitigating Systems Screening Questions. A detailed risk evaluation was performed by a regional senior reactor analyst because the inoperability of both subsystems of ECCS caused a complete loss of the system. A bounding analysis was performed in accordance with the requirements of IMC 0609 Appendix A using the NRC Harris standardized plant analysis risk (SPAR) model. The finding was modelled as a three-hour non-recoverable loss of the high-pressure recirculation function. The dominant sequences were losses of secondary heat removal, successful feed and bleed, recovery of secondary side cooling, and late failure of high pressure recirculation. The risk was mitigated by the short exposure period. The risk increase due to the violation was less than 1E-6 and represented a GREEN finding of very low safety significance.

Corrective Action References: NCRs 02221316 and 02221295 Enforcement Enforcement Action (EA) 19-010: Design Basis 71153 - Follow-up of Discretion Tornado Missile Protection Vulnerabilities to TS Events and Notices of Equipment (EGM 15-002) Enforcement Discretion

Description:

On July 7, 2016, the licensee identified non-conforming conditions in the plant design such that specific TS equipment did not meet current licensing basis for protection against potential tornado missile impacts. Two TS systems contained equipment affected to the extent that the TS operability was impacted. These specific system vulnerabilities included the following:

  • A EDG could be rendered TS inoperable due to potential tornado missile effects on exposed engine control and room damper circuitry conduit or fuel oil supply piping; and,
  • Main steam safety relief valves (MSSVs) could be rendered inoperable due to potential tornado missile crimping the relief valve exhaust piping.

Corrective Actions: The licensee declared the A EDG and MSSVs inoperable due to the potential tornado missile vulnerabilities and promptly restored operability by using the guidelines in NRC Interim Staff Guidance DDS-ISG-2016-01, Clarification of Licensee Actions in Receipt of Enforcement Discretion,(Agencywide Documents Access and Management System (ADAMS) Accession Number ML15348A202), per NRC Enforcement Guidance Memorandum 15-002, Revision 1, Enforcement Discretion for Tornado-Generated Missile Protection Non-Compliance, dated February 7, 2017 (ADAMS Accession Number ML16355A286). Both systems were declared operable, but non-conforming, following the implementation of recommended interim compensatory measures described in EGM 15-002. The licensee reported the non-compliances associated with the EDG and MSSVs in LER 05000400/2016-001-00, dated September 1, 2016. As part of the inspectors review of this issue, the licensees interim compensatory measures were validated to still be in effect. In accordance with the guidance provided in EGM 15-002 for restoring full compliance, on October 19, 2017, the licensee submitted a License Amendment Request (LAR) to incorporate the tornado missile risk evaluator methodology developed under the Nuclear Energy Institute (NEI) Technical Report 17-02, Revision 1, Tornado Missile Risk Evaluator (TMRE) Industry Guidance Document, (ADAMS Accession Number ML17268A036) into the plant tornado missile protection licensing basis. This tornado missile protection evaluation methodology is intended to address plant conditions discovered where tornado missile protection is currently required but is not provided. By letter dated November 21, 2017 (ADAMS Accession Number ML17319A501), the NRC staff provided acceptance for reviewing this LAR. The inspectors determined that the licensee met the EGM 15-002 guidance for submitting an acceptable LAR before the discretion expiration date of June 10, 2018.

Corrective Action References: NCRs 02020044, 01999675, and 02002299

Enforcement:

Violation: 10 CFR Part 50, Appendix B, Criterion III, Design Control, states, in part, that measures shall be established to assure that applicable regulatory requirements and the design basis for those structures, systems, and components to which this appendix applies are correctly translated into specifications and drawings.

Contrary to the above, since original plant construction, the licensee failed to translate the appropriate tornado missile protection requirements into specifications and drawings that would result in structures adequately protecting the A EDG and MSSV components.

Severity/Significance: As discussed in EGM 15-002, the NRC completed a generic risk analysis of the impact of potential tornado missile protection non-conformances. The results of this analysis concluded that this issue was not risk significant because the risk was bounded by an extremely low initiating event frequency for a tornado of 4E-4 per year even in the most severe tornado region. A bounding risk analysis was performed for the condition detailed in LER 05000400/2016-001-00. The issue was evaluated by a regional SRA in accordance with NRC IMC 0609 Appendix A using the NRC Shearon Harris SPAR model.

The issue was modelled as a one-year condition assessment with a simultaneous non-recoverable loss of the MSSVs and the A EDG. The evaluation used the site-specific tornado frequency and the analysis result was less than 1.0E-6/ year, a condition of very low safety significance. The low tornado frequency and remaining mitigation capability mitigated the risk.

Discretion Basis: Because this finding and violation was identified during the discretion period covered by EGM 15-002, Revision 1, and because the licensee was implementing adequate interim compensatory measures to address tornado missile protection vulnerabilities and had submitted a LAR to implement a revised methodology for addressing tornado missile protection that was acceptable to the NRC staff in order to restore full compliance, the NRC is exercising enforcement discretion by not issuing an enforcement action associated with the aforementioned violation and is allowing for continued reactor operation.

The disposition of this violation closes LER 05000400/2016-001-00.

EXIT MEETINGS AND DEBRIEFS

The inspectors confirmed that proprietary information was controlled to protect from public disclosure.

  • On January 9, 2019, and on January 23, 2019, the inspectors presented the quarterly resident inspector inspection results to Ms. Tanya Hamilton, Site Vice President, and other members of the licensee staff.
