UNITED STATES NUCLEAR REGULATORY COMMISSION ber 26, 2018

SUBJECT:

SURRY POWER STATION - NRC PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION REPORT 05000280/2018012 AND 05000281/2081012

Dear Mr. Stoddard:

On October 18, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed a problem identification and resolution inspection at your Surry Power Station Units 1 and 2. On that date, the NRC inspectors discussed the results of this inspection with Mr. Rob Garver, Director of Nuclear Safety and Licensing, and other members of your staff. On November 15, 2018, the inspectors conducted another exit via telephone with Mr. Fred Mladen and other members of your staff. The results of this inspection are documented in the enclosed inspection report.

The NRC inspection team reviewed the stations corrective action program and the stations implementation of the program to evaluate its effectiveness in identifying, prioritizing, evaluating, and correcting problems, and to confirm that the station was complying with NRC regulations and licensee standards for corrective action programs. Based on the samples reviewed, the team determined that your staffs performance in each of these areas adequately supported nuclear safety.

The team also evaluated the stations processes for use of industry and NRC operating experience information and the effectiveness of the stations audits and self-assessments.

Based on the samples reviewed, the team determined that your staffs performance in each of these areas adequately supported nuclear safety.

Finally, the team reviewed the stations programs to establish and maintain a safety-conscious work environment and interviewed station personnel to evaluate the effectiveness of these programs. Based on the teams observations and the results of these interviews the team found no evidence of challenges to your organizations safety-conscious work environment. Your employees appeared willing to raise nuclear safety concerns through at least one of the several means available.

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. 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.

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a Biennial Problem Identification and Resolution Inspection at Surry Power Station Units 1 and 2 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. A licensee-identified non-cited violation is documented in this report.

List of Findings and Violations No NRC-identified or self-revealing findings of more than minor significance were identified.

INSPECTION SCOPE

This inspection was conducted using the appropriate portions of the NRCs inspection procedure 71152, Problem Identification and Resolution issued on February 26, 2015. The inspectors reviewed selected procedures and records, observed activities, conducted plant walk downs, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

REACTOR SAFETY

71152B - Problem Identification and Resolution Biennial Team Inspection

The inspectors performed a biennial assessment of the licensees corrective action program, use of operating experience, self-assessments and audits, and safety conscious work environment. The assessment is documented below.

1) Corrective Action Program Effectiveness: Problem Identification, Problem Prioritization and Evaluation, and Corrective Actions - The inspection team reviewed the stations corrective action program and the stations implementation of the program to evaluate its effectiveness in identifying, prioritizing, evaluating, and correcting problems, and to confirm that the station was complying with NRC regulations and licensee standards for corrective action programs.

The inspectors conducted a detailed review of condition reports and corrective actions associated with the following risk significant systems:

a) Auxiliary Feedwater b) Emergency Diesel Generators c) DC Distribution/Batteries 2) Operating Experience and Self-Assessments and Audits - The team evaluated the stations processes for use of industry and NRC operating experience information and the effectiveness of the stations audits and self-assessments. Based on the samples reviewed, the team determined that stations processes for the use of industry and NRC operating experience information and for the performance of audits and self-assessments were effective and complied with all regulatory requirements and licensee standards. The implementation of these programs adequately supported nuclear safety.

3) Safety Conscious Work Environment - The team reviewed the stations programs to establish and maintain a safety-conscious work environment and interviewed station personnel to evaluate the effectiveness of these programs. Based on the teams observations and the results of these interviews, the team found no evidence of challenges to your organizations safety-conscience work environment. Your employees appeared willing to raise nuclear safety concerns through at least one of several means available.

INSPECTION RESULTS

Corrective Action Program Effectiveness Observations

71152 - Biennial Team

Inspection Based on the samples reviewed, the team determined that the licensees corrective action program (CAP) complied with regulatory requirements and self-imposed standards. The licensees implementation of the CAP adequately supported nuclear safety.

Effectiveness of Problem Identification: The inspectors determined that the licensee was effective in identifying problems and entering them into the CAP and there was a low threshold for entering issues into the CAP. This conclusion was based on a review of the requirements for initiating Condition Reports (CRs) as described in licensee procedure PI-AA-200, Corrective Action, and managements expectation that employees were encouraged to initiate CRs for any reason. Additionally, site management was actively involved in the CAP and focused appropriate attention on significant plant issues.

Based on reviews and walkdowns of accessible portions of selected systems, the inspectors determined that deficiencies were being identified and placed in the CAP.

A minor violation was identified by the inspectors in this area regarding transient combustible material left in the plant.

Effectiveness of Prioritization and Evaluation of Issues: Based on the review of CRs sampled by the inspection team during the onsite period, the inspectors concluded that problems were generally prioritized and evaluated in accordance with the CR significance determination guidance in procedure PI-AA-200. The inspectors determined that in general, adequate consideration was given to equipment operability and associated plant risk.

The inspectors determined that plant personnel had conducted cause evaluations in compliance with the licensees CAP procedures and these cause determinations were appropriate, and considered the significance of the issues being evaluated. A variety of formal causal-analysis techniques were used to evaluate CRs depending on the type and complexity of the issue consistent with the applicable cause evaluation procedures.

A minor violation was identified by the inspectors regarding an issue with a fire door that was not properly evaluated and corrected.

Effectiveness of Corrective Actions: Based on a review of corrective action documents, interviews with licensee staff, and verification of completed corrective actions, the inspectors determined that overall, corrective actions were timely, commensurate with the safety significance of the issues, and effective, in that conditions adverse to quality were corrected.

For significant conditions adverse to quality, the corrective actions directly addressed the cause and effectively prevented recurrence. The team reviewed performance indicators, CRs, and effectiveness reviews, as applicable, to verify that the significant conditions adverse to quality had not recurred. Effectiveness reviews for corrective actions to prevent recurrence (CAPRs) were sufficient to ensure corrective actions were properly implemented and were effective.

A licensee identified violation was documented by the inspectors in this area regarding implementation of maintenance rule requirements.

Licensee Identified Non-Cited Violation

71152 - Biennial Team

Inspection This violation of very low safety significant 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: 10 CFR 50.65(a)(2), Requirements for monitoring the effectiveness of maintenance at nuclear power plants required in part, monitoring as specified in paragraph (a)(1) of this section is not required where it has been demonstrated that the performance or condition of a structure, system, or component is being effectively controlled through the performance of appropriate preventive maintenance, such that the structure, system, or component remains capable of performing its intended function.

Contrary to the requirement, the licensee failed to place the low level vacuum priming instrument air compressor, 1-IA-C-3 in (a)(1) status and monitor as required when performance of the air compressor indicated that it was not being effectively controlled through appropriate preventive maintenance. Specifically, since September 2017, there have been seven (7)maintenance rule (MR) functional failures with five

(5) of those determined to be maintenance preventable functional failures (MPFF) of this air compressor. The licensees current MR program performance criteria for this air compressor is two
(2) maintenance preventable functional failures. The second MPFF occurred on January 1, 2018 and the third MPFF occurred on June 14, 2018. This air compressor is classified as non-safety related, but it is included in the maintenance rule scope because it is considered risk significant. This is because the loss of the compressed air system can lead to the loss of vacuum priming and opening of the vacuum breakers for the circulating water piping, which can result in a rapid decrease in canal level and, barring rapid restoration of instrument air by operators, a trip of both units.

Significance: The inspectors reviewed Exhibit 1 - Initiating Event Screening Questions of IMC 0609 Appendix A, The Significance Determination Process (SDP) for findings at Power and determined this finding was of very low safety significance, Green, because the finding would not lead to an initiating event and affect mitigation equipment.

Corrective Action Reference: CR 1107649

71152 - Biennial Team Minor Violation

Inspection The NRC-identified a minor violation of Technical Specification (TS) 6.4, Unit Operating Procedures and Programs, for the failure to follow the facility fire program in procedure CM-AA-FPA-101, Control of Combustible and Flammable Materials.

On September 28, 2018, the NRC performed an inspection of the Unit 2 Auxiliary Feedwater (AFW) system and identified a 480V electrical extension cable near the turbine driven AFW pump in the Unit 2 main steam valve house. The transient combustible permit for this cable expired on June 29, 2018. Upon identification, the licensee promptly removed the cable.

TS 6.4.E, requires that the facility fire protection program and implementing procedures which have been established for the station be implemented and maintained. The facility fire protection program is partially implemented by procedure CM-AA-FPA-101. Attachment 9 to this procedure states that the Unit 2 safeguards and main steam valve house, Fire Zone 20, shall not have transient combustibles. Contrary to this requirement, the extension cable did not have a valid permit and was considered transient combustible material.

Screening: This violation was considered minor as the transient combustible loading in this fire zone was maintained less than the maximum allowed combustible loading. Additionally, a credible scenario in which the cable could affect AFW pump operation could not be identified.

Enforcement:

This failure to comply with TS 6.4 E constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy. The licensee entered this issue into their CAP as CR 1106069.

71152 - Biennial Team Minor Violation

Inspection The NRC identified a minor violation of Technical Specification (TS) 6.4, Unit Operating Procedures and Programs, for the failure to follow the requirements of licensee procedure CM-AA-FPA-100, Fire Protection/Appendix R (Fire Safe Shutdown) Program, Rev. 13.

TS 6.4.E, required that the facility fire protection program and implementing procedures which have been established for the station be implemented and maintained. The facility fire protection program was implemented by licensee procedure CM-AA-FPA-100. Section 3.11.12 of Attachment 2, Corrective Action of this procedure required in part, measures to ensure that conditions adverse to fire protection such as deviations and non-conformances are promptly identified, reported and corrected. Contrary to this requirement, non-conforming fire door 1-BS-DR-8 was not corrected (compensatory measure established, evaluated and/or repaired) from July 21, 2017 until October 18, 2018 following identification of the issue by the NRC inspectors.

Screening: This violation was considered minor because the inspectors determined that this issue was isolated to a single fire door in the turbine building, was not indicative of a programmatic problem at the station, and a postulated fire in this area would not impact the ability of Unit 1 to achieve safe shutdown.

Enforcement:

This failure to comply with TS 6.4.E constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy. The licensee entered this issue into their CAP as CRs 1107942 and

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

  • On October 18, 2018 and again on November 15, 2018, the inspectors presented the problem identification and resolution inspection results to Mr. Rob Garver, Director of Nuclear Safety and Licensing, and Mr. Fred Mladen, Site Vice President, respectively and other members of the Surry staff.
