List of Findings and Violations

Inadequate Maintenance Procedure for Service Water Bay Inspections and Cleaning Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green [H.5] - Work 71111.12 Systems NCV 05000325/2021001-01 Management Open An NRC-identified finding of very low safety significance (Green) and an associated non-cited violation (NCV) of technical specification (TS) 5.4.1, Procedures, was identified for the failure to provide an adequate maintenance procedure associated with licensee procedure 0PM-STU500 Service Water Intake Structure Inspection and Cleaning. As a result, debris under the pump suction clogged the 1B conventional service water (CSW) pump strainer following pump start, which led to the inoperability of the 1B CSW pump on January 7, 2021.

Additional Tracking Items

None.

PLANT STATUS

Unit 1 began the period at 100 percent (full) rated thermal power (RTP) and essentially operated there for the entire inspection period.

Unit 2 began the period at 100 percent RTP and operated there until February 16 when the unit was derated to 87 percent due to the loss of one of the four Unit 2 main switchyard lines. Following restoration of the off-site power line on February 17, the unit was stored to full power where it continued to operate until March 6 when the unit was shut down for a refueling outage. The unit remained shut down 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.

Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the Coronavirus Disease 2019 (COVID-19), resident inspectors were directed to begin telework and to remotely access licensee information using available technology. During this time, the resident inspectors performed periodic site visits each week; conducted plant status activities as described in IMC 2515, Appendix D, Plant Status; observed risk-significant activities; and completed on-site portions of IPs. In addition, resident and regional baseline inspections were evaluated to determine if all or portions of the objectives and requirements stated in the IP could be performed remotely. If the inspections could be performed remotely, they were conducted per the applicable IP. In some cases, portions of an IP were completed remotely and on-site. The inspections documented below met the objectives and requirements for completion of the IP.

OTHER ACTIVITIES

- TEMPORARY INSTRUCTIONS, INFREQUENT AND ABNORMAL 2515/194 - Inspection of the Licensees Implementation of Industry Initiative Associated With the Open Phase Condition Design Vulnerabilities In Electric Power Systems (NRC Bulletin 2012-01)

The inspectors reviewed the licensees implementation of the Nuclear Energy Institute Voluntary Industry Initiative, (ADAMS Accession No. ML15075A454) dated March 16, 2015.

This included reviewing how the licensee updated their licensing basis to reflect the need to protect against open phase conditions.

Inspection of the Licensees Implementation of Industry Initiative Associated With the Open Phase Condition Design Vulnerabilities In Electric Power Systems (NRC Bulletin 2012-01)

(1 Sample)

(1) Revision 0 of this Temporary Instruction (TI) was previously inspected, and closed, in Inspection Report 2019012 (ADAMS ML19324D085). However, a subsequent revision to the Nuclear Energy Institute (NEI) Voluntary Initiative (Revision 3) provided plants the option of to leave the open phase protection system in monitoring mode only in lieu of activating the automatic trip circuitry, provided it was supported by a risk evaluation. Revision 1 (and later Revision 2) of this TI was issued to provide inspection guidance for the new option.

The inspectors reviewed licensee analyses and procedures that demonstrated operator manual actions would successfully mitigate the impact of an Open Phase Condition (OPC). The analyses were reviewed remotely, and the procedures were reviewed and walked down on site. The inspectors completed Section 03.01c of TI 2515/194, Revision 2.

The inspectors verified that modeling used for the OPC reflected the as-designed and as-built plant, assumptions made by the licensee were reasonable, and licensee procedures were adequate to successfully respond to an OPC. The inspectors also verified that human reliability analysis and recovery evaluations were done in accordance with NEI and voluntary initiative guidance.

INSPECTION RESULTS

Observation: TI-194 Observations 2515/194 The licensee's probabilistic risk assessment analysis for Brunswick's open phase condition credits operator recovery of equipment once the open phase condition is cleared. To support this analysis the license provided engineering calculation BNP-E-4.008, Open Phase Condition Response Time, Revision 00, which supported the licensee's position that credited equipment would not be damaged by the open phase condition prior to the local over current protection devices tripping and protecting the equipment. The inspectors verified that procedures were in place to aid the operators in restoring the credited equipment and that sufficient time was available to complete the required actions and human error probabilities were developed and were reasonable.

Inadequate Maintenance Procedure for Service Water Bay Inspections and Cleaning Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green [H.5] - Work 71111.12 Systems NCV 05000325/2021001-01 Management Open An NRC-identified finding of very low safety significance (Green) and an associated non-cited violation (NCV) of technical specification (TS) 5.4.1, Procedures, was identified for the licensees failure to provide an adequate maintenance procedure associated with licensee procedure 0PM-STU500 Service Water Intake Structure Inspection and Cleaning. As a result, debris under the pump suction clogged the 1B conventional service water (CSW)pump strainer following pump start, which led to the inoperability of the 1B CSW pump on January 7, 2021.

Description:

On January 6, 2021, the 1B CSW pump was declared out of service for SW bay inspection and cleaning. TS action statement 3.7.2 condition C was entered for the service water system and ultimate heat sink (UHS). On January 7, 2021, TS 3.7.2 was exited. The 1B CSW pump was started and the running 1C CSW pump secured. Operators in the control room received 1-UA-1 (5-8) Conventional Pump Strainer B Diff-High and 1-UA-24 (1-1)

Conventional Header Service Water Press-low alarms.

The 1B CSW pump strainer differential pressure (DP) was reported at 9.8 psid and slowly increasing. The 1B CSW pump strainer was not rotating with the motor running which is contrary to normal operation of the strainer. The licensee restarted the 1C CSW pump to restore conventional header pressure. The licensee decision making process concluded the 1B CSW pump was inoperable because the strainer DP was greater than 8 psid.

Maintenance personnel discovered the 1B CSW pump strainer was clogged with 15 gallons of oyster shells and the motor shear pin was broken. The strainer was cleaned, and the motor shear pin replaced. On January 10, 2021, the 1B CSW pump strainer was returned to service and the TS LCO was exited.

Inspectors reviewed licensee procedure 0PM-STU500, Service Water Intake Structure Inspection and Cleaning and noted step 7.2.17 was to ensure shells have not settled under the service water pump suctions during cleaning activities to avoid strainers being clogged following pump start. Inspectors questioned whether the procedure was followed correctly. The licensee did not have sufficient records (i.e. video) to demonstrate that the 1B SW bay was cleaned properly due to limited access around the pump suction and poor water visibility (6 to 12 inches). However, the licensee believed the loose debris most likely came from the adjacent uncleaned 1C CSW pump bay area which was disturbed when the associated pump was secured. This debris was then ingested by the 1B CSW pump. This rapid influx of debris resulted in the backwash line becoming clogged, the strainer motor shear pin breaking, and a high strainer DP until the pump was secured. The procedure does not specify which adjacent CSW pump should be running during the pump bay cleaning. In this case, the procedure could have specified operation of the previously cleaned 1A CSW pump instead of the 1C CSW pump. This could have prevented the debris from the uncleaned bay from getting ingested during 1B CSW pump start and the subsequent inoperability of the 1B CSW pump.

Corrective Actions: The licensee repaired the broken motor shear pin and cleaned the strainer of debris. The 1B CSW pump was declared operable on January 10, 2021. The licensee is evaluating the pump bay cleaning procedure regarding the running of adjacent CSW pumps.

Corrective Action References: AR 2364279

Performance Assessment:

Performance Deficiency: Failure to provide an adequate maintenance procedure to clean and inspect the interior pump bay areas was a performance deficiency. This resulted in inoperability of the 1B CSW pump on January 7, 2021.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Procedure Quality attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the maintenance procedure did not ensure the interior pump bays were clean which led to the clogging of the 1B CSW pump strainer and inoperability of the 1B CSW pump on January 7, 2021.

Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The finding was screened under Exhibit 2 - Mitigating Systems Screening Questions and was determined to be of very low safety significance (Green) because all screening questions were answered no.

Cross-Cutting Aspect: H.5 - Work Management: The organization implements a process of planning, controlling, and executing work activities such that nuclear safety is the overriding priority. The work process includes the identification and management of risk commensurate to the work and the need for coordination with different groups or job activities.

Enforcement:

Violation: Technical Specifications 5.4.1.a, Procedures required in part, written procedures shall be established, implemented and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Appendix A, November 1972.Section I.1 of Appendix A of Regulatory Guide 1.33, required in part, maintenance which can affect the performance of safety-related equipment should be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances.

Contrary to the above, licensee procedures used to perform Service Water Intake Structure Inspection and Cleaning were not appropriate to the circumstances. Specifically, the maintenance procedures did not ensure the interior pump bay areas were clean prior to pump start. As a result, debris settled under the pump suction and clogged the 1B CSW pump strainer during pump start. The 1B CSW pump was declared inoperable due to the high DP on January 7, 2021.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
