List of Findings and Violations Loss of Primary Component Cooling Water Cornerstone Significance Cross-Cutting Report Aspect Section Initiating Events Green NCV H.12 - Avoid 71153 05000443/2018004-01 Complacency Follow-up of Closed Events and Notices of Enforcement Discretion A self-revealing Green non-cited violation (NCV) was identified when Seabrook did not follow a procedure (Regulatory Guide 1.33, Appendix A) required by Technical Specification (TS) 6.7.1. Specifically, while performing procedure OS1012.04, Primary Component Cooling Water Loop B, Revision 28, Seabrook did not unlock and close the A head tank isolation valve resulting in a loss of primary component cooling water, and impacted the ability to remove decay heat from the core.
PLANT STATUS
Seabrook began the inspection period with the main turbine generator shutdown, reactor power below 8 percent rated thermal power, and a shutdown in-progress for entry into refueling outage No. 19 (OR19). On October 27, the reactor achieved initial criticality, and synchronized the main turbine generator to the power grid on October 28, and achieved 100 percent rated thermal power on October 31. There were no operational power changes of regulatory significance for the remainder of the inspection period.
INSPECTION SCOPES
Inspections were conducted using the appropriate portions of the inspection procedures in effect at the beginning of the inspection unless otherwise noted. Currently approved inspection procedures 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 inspection procedure 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 Inspection Procedure (IP) 71152, Problem Identification and Resolution.

INSPECTION RESULTS
Observation 71152.1 Semiannual Trend Review The inspectors evaluated a sample of condition reports generated over the course of the past two quarters, and the Seabrook Station Q3 2018 Self-Evaluation and Trending Analysis Report. The inspectors also verified the analysis and report was conducted in accordance with PI-AA-207-1000, Station Self-Evaluation and Trending Analysis, Revision 9. The inspectors evaluated a sample of inputs from departments that provide input to the quarterly report. The inspectors determined that, in general, the issues were appropriately evaluated by Seabrook staff for potential trends and resolved within the scope of the corrective action program. However, the inspectors noted in one instance a station-identified adverse trend associated with recurrent problems with the meteorological tower was planned for closure at the end of the third quarter trending assessment period. The tower is important to implementation of the emergency plan. The inspectors observed that new deficiencies associated with equipment on the tower that should have warranted NextEras continued monitoring of the adverse trend into the fourth quarter.
Subsequently, the inspectors observed a November meeting to review and approve the Q3 Trend Report. During this meeting, the stations Management Review Committee appropriately elevated the issues associated with the tower and its associated equipment to a higher significance within the corrective action program. This elevation of significance within the corrective action program is designed to ensure appropriate evaluation and implementation of corrective actions to resolve the ongoing issues with the tower and its associated equipment. The inspectors noted that this evaluation was also appropriate based on the Management Review Committees recognition of its importance to the implementation of the Emergency Plan.
Observation 71152.2(1)
Annual Follow-up of Selected Issues The inspectors assessed Seabrooks corrective actions associated with AR2265706 to address the recommendations of the Nuclear Safety Assessment Letter 18-1, Thermal Sleeve Flange Wear Leads to Stuck Control Rod. This condition was identified at a foreign nuclear power plant and is described in NRC Information Notice 2018-10 (ML18214A710). The inspectors reviewed NextEras procedure, measurement results and technical evaluation.
The inspectors determined NextEras response was timely, commensurate with the safety significance of the issue, and included appropriate corrective actions.
Loss of Primary Component Cooling Water Cornerstone Significance Cross-Cutting Report Aspect Section Reactor Safety - Green NCV H.12 - Avoid 71153 Initiating Events05000443/2018004-01 Complacency Follow-up of Closed Events and Notices of Enforcement Discretion A self-revealed Green non-cited violation (NCV) was identified when Seabrook did not follow a procedure (Regulatory Guide 1.33, Appendix A) required by TS 6.7.1. Specifically, while performing procedure OS1012.04, Primary Component Cooling Water Loop B, Revision 28, Seabrook did not unlock and close the A head tank isolation valve resulting in a loss of primary component cooling water, impacting the ability to remove decay heat from the core.
Description:
On October 7th during a cross-tie evolution of the A and B primary component cooling water trains in accordance with OS1012.04, the B primary component cooling water head tank level began to lower. Prior to the event, Seabrook had secured the A residual heat removal and A primary component cooling water pumps in preparation for outage-related maintenance, and established conditions for core offload by maximizing cooling to the spent fuel pool heat exchanger. Although unknown at the time of the event, because the A train head tank isolation valve was not closed as required by the steps in OS1012.04, the B primary component cooling water head tank level continued to lower as the B train inventory was transferred to the A train head tank. In response, operators manually secured the B primary component cooling water pump due to evidence of cavitation, which resulted in a loss of all primary component cooling water system flow to both the spent fuel pool and shutdown cooling heat exchangers.
Seabrook appropriately entered TS 3.9.8.1, Residual Heat Removal and Coolant Circulation, because the residual heat removal system was unable to effectively remove decay heat from the core via the primary component cooling water and residual heat removal heat exchangers. During subsequent system restoration, Seabrook identified the 'A' primary component cooling water head tank isolation valve had not been repositioned to the closed position during the cross-tie evolution, causing the B head tank water inventory to transfer to the A head tank. Based on a review of the applicable TS and TS Bases, the inspectors determined the residual heat removal safety function was not lost because reactor vessel water temperature was less than 140°F, and sufficient coolant circulation was maintained through the core with residual heat removal pumps still in operation, to minimize the effect of a boron dilution event and prevent boron stratification.
Corrective Actions: The short term corrective actions included backing out of the cross-tie procedure, identification of the valve misalignment, and restoration of the primary component cooling water system to normal operation using normal and abnormal operating procedures.
Additionally, on October 9, 2018, NextEra Senior Management completed a special, internal team assessment using fleet resources, to evaluate risk recognition and mitigation drivers that contributed to the loss of primary component cooling water event. Also, the NextEra fleet assessment reviewed previous human performance events from the last refueling outage, as well as other human performance deficiencies that were identified during the operating cycle.
Seabrook initiated a root cause evaluation to identify root and contributing causes, and applicable short and long-term corrective actions. Seabrook also identified the risk process for online and outage work activities performed by work management during scheduling and planning was not applied to the primary component cooling water cross-tie evolution. In addition, Seabrook also developed a case study to address risk management fundamentals.
Corrective Action References: AR 02284272
Performance Assessment:
Performance Deficiency: Seabrook TS 6.7.1.a. states that written procedures shall be implemented covering activities described in Regulatory Guide 1.33. Regulatory Guide 1.33, Revision 2, Appendix A, paragraph 3, lists procedures for shutdown, safety-related pressurized water reactor systems. Item 'e' specifically lists Component Cooling Water System, which for Seabrook, is the primary component cooling water system. Procedure OS1012.04 provides step-by-step instructions on the operation of the primary component cooling water system.
Screening: The inspectors used IMC 0612, Appendix B, to determine the performance deficiency was more than minor. The improper shutdown equipment lineup was associated with the configuration control attribute of the Initiating Events Cornerstone and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown operations. Specifically, Seabrook did not properly implement procedure OS1012.04, resulting in loss of primary component cooling water, and impacted the ability to remove decay heat from the core. The finding was screened in accordance with IMC 0609 Appendix G, Attachment 1, Shutdown Operations Significance Determination Phase 1 Initial Screening and Characterization Of Findings. The finding represents an initiating event loss of component cooling water scenario which impacts the decay heat removal safety function.
Significance: In accordance with IMC 0609, Appendix G, Attachment 1, the finding did not screen to green and involved a detailed risk analysis. A Region I Senior Reactor Analyst performed a risk evaluation for the finding using the guidance within IMC 0609, Appendix G, 2, Phase 2 significance determination process template for a pressurized water reactor during shutdown conditions. Specifically, Table 4 and Worksheet 9 were used to perform an estimate of the risk increase. Although there is no worksheet for plant operating State 3 for loss of residual heat removal, the Senior Reactor Analyst conservatively used Worksheet 9 for plant operating state 2 as a surrogate to be a bounding condition. Plant operating state 3 would typically apply in operating Mode 6 with a reactor vessel flooded-up condition. The core damage sequences of interest were the initiating event likelihood for loss of residual heat removal, with a failure to recover the residual heat removal support system (i.e. primary component cooling water), and failure to recover residual heat removal, with failure of makeup to the refueling water storage tank. The second sequence was the initiating event likelihood for a loss of residual heat removal with failure to recover the support system for residual heat removal and failure to feed the reactor pressure vessel due to reactor coolant system boil-off. Both sequences resulted in core damage sequences of a conditional core damage probability of E-11. However, the Senior Reactor Analyst conservatively clamped the mitigating strategies probability of failure at E-5 in accordance with guidance within Risk Assessment of Operating Events, Volume 4, Shutdown Event Review, Revision 1.0. Appendix B provides guidance on the treatment of operator actions and Table B-1.4 provides limitations for total human error probability credit for the core damage sequences, which accounts for dependency for operator failure actions. Although the Senior Reactor Analyst noted there would likely be weak dependency due to excessive time to accomplish actions (i.e at least 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> to calculated time to boil) and actions having cues with simple tasks, a nominal operator failure HEP of 1E-5 was used as a cutoff for all mitigation credit. The initiating event likelihood with the mitigating actions resulted in an estimated increase in core damage frequency of E-9/yr, or of very low safety significance (Green).
The Senior Reactor Analyst noted that Table 5 within Appendix B of the Risk Assessment of Operating Events, Volume 4 for condition findings, was noted to not apply to loss of residual heat removal conditions for the plant operating state 3. This further indicates the assumed low risk given the plant configuration. This is due, in part, to the amount of time to boil (estimated at 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />), and the volume of reactor coolant system water with the vessel flooded up.
Cross Cutting Aspect: The inspectors determined this finding affected the cross-cutting area of human performance in the aspect of avoid complacency (H.12), where individuals recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Individuals implement appropriate error reduction tools. The inspectors found the most-significant contributor to the event was because individuals did not implement appropriate error reduction tools during operation of valves associated with the primary component cooling water system.
Enforcement:
Violation: Technical Specification 6.7.1 requires applicable procedures recommended in Appendix A of Regulatory Guide 1.33, to be established, implemented, and maintained.
Procedure OS1012.04 Primary Component Cooling Water Loop B (Rev. 28) Step 4.7.6.4, requires unlocking and closing the A head tank isolation valve.
Contrary to the above, on October 7, 2018, while in Mode 6, Seabrook inadequately implemented OS1012.04 Steps 4.7.6.4 when operators did not unlock and close the A head tank isolation valve when cross-tying the A and B primary component cooling water trains causing a loss of primary component cooling water and impacting the ability to remove decay heat from the core.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
