SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring licensees performance by conducting a quarterly integrated 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. NRC and self-revealed findings, violations, and additional items are summarized in the table below.

List of Findings and Violations None.

Additional Tracking Items Type Issue number Title Report Status Section LER 05000280/2018-001-00 Loss of 4160 Volt Emergency 71153 Closed Bus and Start of Emergency Diesel Generator due to Opening Emergency Bus Potential Transformer Drawer

PLANT STATUS

Unit 1 operated at or near 100 percent rated thermal power for the entire inspection period.

Unit 2 began the inspection period at or near 100 percent rated thermal power. On January 6, 2018, the unit was down powered to 75 percent due to clogging of the trash racks in the high level intake structure. The unit was returned to full rated thermal power on January 7, 2018, and remained at or near full rated thermal power for the remainder of the 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 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.

The inspectors evaluated the following licensee event report which can be accessed at https://lersearch.inl.gov/LERSearchCriteria.aspx:

(1) Licensee Event Report (LER) 05000280/2018-001-00, Loss of 4160 Emergency Bus and Start of Emergency Diesel Generator due to Opening Emergency Bus Potential Transformer Drawer, on January 17,

INSPECTION RESULTS

Observation 71152 The inspectors performed a review of the licensees corrective action program documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors review was focused on repetitive equipment and corrective maintenance issues, but also considered the results of daily inspector corrective action program item screening.

The review included issues documented outside the normal correction action program in system health reports, corrective maintenance work orders, component status reports, site monthly meeting reports, and maintenance rule assessments. The inspectors review nominally considered the six month period of July through December, 2017, although some examples extended beyond those dates when the scope of the trend warranted.

The inspectors compared and contrasted their results with the results contained in the licensees latest condition report trending/human performance trends. Corrective actions associated with a sample of the issues identified in the licensees trend report were reviewed for adequacy. In general, the licensee has identified trends and has addressed the trends with their corrective action program. No new adverse trends were identified this period that had not already been identified by the licensee.

Observation 71153 The licensee conducted an Apparent Cause Evaluation (ACE) and determined the operations team, while reviewing the electrical tag-out walkdown task, did not adequately perceive and manage the risk of opening the 1J emergency bus potential transformer drawer under the existing plant conditions. Therefore, contingencies, stop criteria, and other risk mitigation actions were not established. Additionally, the operator who opened the drawer did not understand the impact to the 1J emergency bus UV sensing circuit when opening the 1J emergency bus potential transformer drawer. The inspectors reviewed the LER, the associated ACE and corrective actions, and interviewed licensee staff. This LER is closed.

EXIT MEETINGS AND DEBRIEFS

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

On April 12, 2018, the inspector presented the quarterly resident inspector inspection results to R. Simmons, Surry Plant Manager, and other members of the licensee staff.
