Units 1, 2, and 3 operated at or near rated thermal power for the entire 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 (COVID-19), resident and regional 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, increasing the amount of time on site as local COVID-19 conditions permitted. As part of their onsite activities, resident inspectors conducted plant status activities as described in IMC 2515, Appendix D; 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.

INSPECTION RESULTS
Inadequate Procedure for Transport of the Containment Hydrogen Recombiners Cornerstone Significance Cross-Cutting Aspect Report Section Barrier Integrity
Green NCV 05000529,05000530,05000528/2020003-01 Open/Closed
[H.6] - Design Margins 71111.04 The inspectors identified a Green, non-cited violation of Technical Specification 5.4.1.a, Procedures, for the licensees failure to maintain an appropriate procedure for changing the mode of operation of the containment hydrogen recombiner system during a loss-of-coolant accident (LOCA) in Unit 2 or Unit 3. Specifically, hydrogen recombiner B, shared among the three units, was not physically capable of being moved out of its normal location in Unit 1, or installed in Unit 2 or Unit 3, without removing permanently-installed plant equipment obstructing the transport path of the recombiner, and necessary steps to remove the equipment were not addressed in the licensees procedure.
Description:
The containment hydrogen control system includes two 100 percent capacity redundant safety-related trains of hydrogen recombiners and a single-train nonsafety-related hydrogen purge system that is a backup system to the recombiners. The design requirement is to maintain containment hydrogen concentration less than 4.0 volume percent following a LOCA. The hydrogen recombiners and the hydrogen purge system are shared among the three units. The equipment is installed in the Unit 1 auxiliary building and each component is intended to be transportable to Units 2 or 3 if there was a LOCA in one of those units. The hydrogen recombiner skids are each approximately 5.5 feet wide, 10.5 feet long, and weigh 11,000 pounds. The cylindrical recombiner body on the skid is approximately 5.3 feet in diameter and 8.5 feet tall. By design the recombiners are required to be installed within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> of the initiation of a LOCA, warm-up for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and then placed in service within 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> of the initiation of a LOCA.
On June 3, 2020, while hydrogen recombiner A was nonfunctional due to a corrective maintenance item, the inspectors performed a walkdown of the hydrogen control system and identified a potential lack of clearance for transport of the hydrogen recombiner B skid out of the Unit 1 auxiliary building. The path of travel for the B skid was blocked by emergency lighting battery bank 1QDN-N08. The inspector reviewed Procedure 31MT-9HP01, Hydrogen Recombiner/Hydrogen Purge Exhaust Air Filtration Unit Removal and Installation, Revision 8. This procedure provided instructions for the transport of the hydrogen recombiners following a LOCA. The procedure did not identify the obstruction or provide steps to remove it. The licensee confirmed the inspectors observation and initiated Condition Report 20-07585. The licensee concluded the hydrogen recombiner B remained functional because removal of battery bank 1QDN-N08 was estimated to only require 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> of time, leaving ample time available to move and install the skid in Unit 2 or Unit 3.
On June 8, 2020, the inspectors performed a walkdown of the hydrogen recombiner B transport path in Units 2 and 3. The inspector identified other potential obstructions that would prevent the hydrogen recombiner skid from being moved to its required location. These permanently installed components included fire panel 2EFPNJ22J in Unit 2 and fire panel 3EFPNJ32J in Unit 3. These interferences were also not addressed by Procedure 31MT-9HP01. The licensee confirmed these observations and added them to Condition Report 20-07585 for evaluation. The licensee completed additional walkdowns and concluded these fire panels and some other miscellaneous light fixtures and minor obstructions would require removal to allow transport and installation of the hydrogen recombiner B skid. The licensee updated its functionality assessment with information that 12-18 hours would be required to remove the additional obstructions and this work could be performed in parallel with the removal of the hydrogen recombiner B skid from the Unit 1 auxiliary building. The licensee concluded there was still sufficient time available to install the recombiner within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> and, therefore, the hydrogen recombiner B remained functional. The licensee initiated a procedure change request to revise Procedure 31MT-9HP01 to include the required plant modifications to support removal and installation of the hydrogen recombiner B skid.
Due to differences in equipment layout in the auxiliary buildings, the inspectors did not have a concern with transportability of the hydrogen recombiner A skid out of Unit 1 and into Unit 2 or Unit 3.
Corrective Actions: The licensee completed walkdowns in all three units to identify obstructions requiring removal to support transport of the hydrogen recombiner and documented a functionality assessment of the hydrogen recombiner. The licensee also initiated a corrective action item to revise Procedure 31MT-9HP01.
Corrective Action References: Condition Reports 20-07585, 20-12271
Performance Assessment:
Performance Deficiency: The licensees failure to maintain an adequate procedure for the removal of the hydrogen recombiner B skid from Unit 1 and installation in Unit 2 or Unit 3 following a LOCA was a performance deficiency.
Screening: The inspectors determined the performance deficiency was more than minor because it adversely affected the design control and procedure quality attributes of the Barrier Integrity Cornerstone and impacted the cornerstone objective to provide reasonable assurance that physical design barriers (containment) protect the public from radionuclide releases caused by accidents or events. Procedure 31MT-9HP01 only provided instructions for removal and installation of one hydrogen recombiner. Absent guidance to move both hydrogen recombiner skids following a LOCA, and absent an unobstructed travel path for hydrogen recombiner B, the inspectors concluded the time available to place a hydrogen recombiner in service was significantly challenged if there were a failure of hydrogen recombiner A.
Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors assessed the significance of the finding using Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated December 13, 2019. The inspectors determined that the finding had very low safety significance (Green) because it did not represent an actual open pathway in the physical integrity of reactor containment (valves, airlocks, etc.), failure of containment isolation system (logic and instrumentation), failure of containment pressure control equipment (including structures, systems or components credited for compliance with Order EA-13-109), failure of containment heat removal components; and, the facility does not have a containment design that uses hydrogen igniters (Exhibit 3, Section C).
Cross-Cutting Aspect: H.6 - Design Margins: The organization operates and maintains equipment within design margins. Margins are carefully guarded and changed only through a systematic and rigorous process. Special attention is placed on maintaining fission product barriers, defense-in-depth, and safety-related equipment. The finding has a cross-cutting aspect in the area of human performance associated with the design margins component because the licensee failed to carefully guard and maintain design margin through a systematic and rigorous process. Specifically, emergency lighting battery banks were permanently installed in September 2018, June 2019, and July 2019 (for Units 1, 3, and 2 respectively) that obstructed the travel path of hydrogen recombiner B. This was not recognized, assessed, and included in the licensees procedure for removal, transport, and installation of a hydrogen recombiner during a LOCA. Ultimately, this resulted in loss of design margin for placing the hydrogen removal system in service. [H.6]
Enforcement:
Violation: Technical Specification 5.4.1.a, Procedures, requires, in part, that written procedures shall be established, implemented and maintained covering the applicable procedures listed in Appendix A to Regulatory Guide 1.33, Quality Assurance Program Requirements, Revision 2, February 1978. Regulatory Guide 1.33, Appendix A, Section 3.v, states, in part, that instructions for startup, shutdown, and changing modes of operation should be prepared, as appropriate, for the hydrogen recombiner system.
Contrary to the above, prior to June 8, 2020, the licensee did not maintain an appropriate procedure for startup, shutdown, and changing the mode of operation of the hydrogen recombiner system during a loss-of-coolant accident in Unit 2 or Unit 3. Specifically, station Procedure 31MT-9HP01, Hydrogen Recombiner/Hydrogen Purge Exhaust Air Filtration Unit Removal and Installation, Revision 8, did not have appropriate instructions for transporting hydrogen recombiner B, shared among the three units, from its normal location in Unit 1, to Unit 2 or Unit 3 during a LOCA in one of those units. Previously unidentified, permanently-installed plant equipment created obstructions to the transport of the hydrogen recombiner B from Unit 1 to Unit 2 or Unit 3 following a LOCA, and removal of this equipment was not addressed in Procedure 31MT-9HP01.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
