INSPECTION RESULTS

Failure to Adequately Describe Discovered Degraded Condition of Service Water Pump House Ventilation Equipment In Accordance With The Corrective Action Program Cornerstone Significance Cross-cutting Aspect Report Section Mitigating Green None 71111.21M -

Systems NCV 05000338, 339/2018010-01 Design Bases Closed Assurance Inspection The inspectors identified a Green finding and associated Non-Cited Violation (NCV) of Criterion V, Instructions, Procedures, and Drawings, in Appendix B of 10 Code of Federal Regulations (10 CFR), for the licensees failure to follow their corrective action procedure.

Specifically, entering degraded conditions into the stations corrective action program is an activity affecting quality, and station personnel did not accomplish the activity in accordance with the prescribed steps in procedure PI-AA-200. As a result, the licensee failed to perform required operability/functionality and maintenance rule evaluations and delayed taking corrective actions.

Description:

The North Anna Power Station Updated Final Safety Analysis Report (UFSAR) section 9.4.10.2, System Description and Evaluation, stated:

The service water ventilation system consists of two redundant exhaust fans with associated dampers connected to separate emergency power sources. All fans, dampers, and damper operators are seismically qualified. Each fan is interlocked with two supply air dampers and has the capacity to maintain the design space temperature. Therefore, a single failure of a fan damper, or damper operator, does not adversely affect the equipment in the space.

The Service Water Pumphouse (SWPH) ventilation system is considered a support system for the Service Water (SW) system and is not directly discussed in the plant Technical Specifications (TS). However, TS Bases 3.7.8, Background, stated, The SW System has sufficient redundancy to withstand a single failure, including the failure of an emergency diesel generator on the affected unit.

When either of the two redundant trains of SWPH ventilation is non-functional, the system does not meet its description in UFSAR section 9.4.10.2. Additionally, the SW system would not be able to withstand a single failure as stated in its TS bases. This loss of conformance to the licensing basis descriptions represents a non-conforming condition as defined in station procedure, OP-AA-102, Operability Determination, which expected corrective actions to be completed at the first opportunity to resolve the non-conforming condition.

The inspectors identified an example where the licensee did not describe a non-conforming condition in a condition report (CRs) in accordance with procedure PI-AA-200, Corrective Action. The revision of the procedure in use at the time of the CR entry required the CR writer to PROVIDE sufficient information to ensure that the deviating condition can be understood by subsequent reviewers. and it also required the CR writer to provide or identify the following information on the CR: the missed expectation, the consequence of the deviating condition, and the risk associated with it. An attachment to the procedure further stated that Sufficient information is required to allow proper operability and reportability determinations to be performed.

While reviewing corrective action documents and operations logs, inspectors noted that the description in CR 325048, dated February 27, 2009, did not fully describe a discovered degraded condition on a SWPH exhaust fans motor operated damper. It described the discovered condition as a missing pivot pin in damper 1-HV-MOD-127B-1, associated with SWPH exhaust fan 1-HV-F49B. No impact or potential impact to the required function of the damper or SWPH ventilation system was described in the CR, and no operability or functionality evaluation was requested to be completed. Additionally, a maintenance rule functional failure determination was not requested to be performed regarding the described condition.

Review of operations logs, recorded around the time the CR was written, revealed that motion in the motor-operated damper was the opposite of what was demanded (i.e., open when desired closed, closed when desired open); this detail was not discussed in the CR. In this condition, the SWPH ventilation system, as a support system to the SW system, would not have met its functional description in the UFSAR or the TS Bases, and neither the SWPH ventilation system nor the SW system were considered non-conforming. Because the opposite trains fan and dampers were functional at the time of the degraded condition, the SW system was correctly considered operable, although the SWPH ventilation system should have been considered non-conforming. The degraded fan damper was eventually repaired in June 2009 under work order 59076838401.

Corrective Actions: The licensee entered the issue into their corrective action program and recommended additional communication and staff training to ensure conformance to their PI-AA-200 procedure.

Corrective Action Reference: CR 1111471

Performance Assessment:

Performance Deficiency: The inspectors determined that the licensees failure to describe the missed expectation, the consequence of the deviating condition, and the risk associated with it in the CR, as required by procedure PI-AA-200, Corrective Action, was a performance deficiency.

Screening: The performance deficiency was more than minor because the performance deficiency was associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the result of the failure to adequately describe the degraded condition in the condition report was missed evaluations of operability/functionality, reportability, and reliability. Since the condition documented in the CR represented a degradation of the system to below the functional description in the stations UFSAR, the licensee, had they performed an operability/functionality assessment, would have considered the support system non-conforming and required it to be fixed at the first available opportunity.

Significance: The team evaluated the finding in accordance with NRC Inspection Manual Chapter (IMC) 0609, Attachment 4, Initial Characterization of Findings, issued October 7, 2016, for Mitigating Systems, and IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, issued June 19, 2012, and determined the finding to be of very low safety significance (Green) because the finding was a deficiency affecting the design of a mitigating structure, system, or component (SSC), and the SSC maintained its operability or functionality. Specifically, although the condition resulted in the SWPH Ventilation System deviating from its description in the UFSAR, the unaffected train was sufficient to support operability of the SW pumps.

Cross Cutting Aspect: No cross cutting aspect was assigned to this finding because the inspectors determined the finding did not reflect present licensee performance.

Enforcement:

Violation: Criterion V, Instructions, Procedures, and Drawings, in Appendix B of 10 CFR 50, required, in part, Activities affecting quality shall be prescribed by documented instructions, procedures, and drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures or drawings.

Contrary to the above, in 2009, the licensee did not accomplish an activity affecting quality in accordance with their prescribed procedure. Specifically, entering degraded conditions into the stations corrective action program is an activity affecting quality, and station personnel did not accomplish the activity in accordance with the prescribed steps in procedure PI-AA-200.

Enforcement Actions: This violation is being treated as a Non-Cited Violation, consistent with Section 2.3.2 of the Enforcement Policy.

EXIT MEETINGS AND DEBRIEFS

The inspectors confirmed that proprietary information was controlled to protect from public disclosure.

• On November 30, 2018, the inspectors presented the design bases assurance (team)inspection results to Mr. E. Hendrixson, Director of Engineering, and other members of the licensee staff.
