List of Findings and Violations
Failure to Properly Evaluate Design Change to Emergency Diesel Generator Day Tank Level Control and Indication Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green None 71111.15 Systems NCV 05000368/2020003-01 Open/Closed The inspectors identified a Green finding and associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the failure to appropriately verify the adequacy of a design change made in 1997 for safety-related emergency diesel generator fuel oil day tank transfer components. Specifically, the licensee failed to properly evaluate the electrical and thermal loads within the enclosures, resulting in a reasonable doubt with respect to the qualification of the day tank level control electronics to be able to operate in the environment of the enclosures.
Additional Tracking Items
None.
PLANT STATUS
Unit 1 began the inspection period at full power where it remained for the rest of the reporting period except for minor reductions in power to support scheduled surveillances.
Unit 2 began the inspection period at full power and remained at full power until September 9, 2020, when the unit reduced power to 94 percent to investigate a suspected leak in high pressure feedwater heater 2E1B. After determination there was no leak, Unit 2 returned to full power on September 10, 2020, where it remained for the rest of the reporting period except for minor reductions in power to support scheduled surveillances.
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 a portion 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 2690/011 - Review of Aging Management Programs at Independent Spent Fuel Storage Installations The inspectors evaluated whether the licensee had adequate procedures in place to implement an Aging Management Program (AMP) for their independent spent fuel storage installation (ISFSI) from September 17-20, 2019, and conducted an in-office review of additional information including the inspection results from July 14-16, 2020, and September 28-30, 2020.
Review of Aging Management Programs at Independent Spent Fuel Storage Installations (1 Sample)
- (1) The overall program and implementing procedures that the licensee had in place to implement the AMP were inspected in accordance with paragraphs 03.01-03.10 of the temporary instruction and the inspectors found the licensees program and procedures consistent with the AMP provided in the renewed Certificate of Compliance (CoC) for the Westinghouse Electric Companys ventilated storage casks (VSCs) system (Docket No. 72-1007), formerly EnergySolutions. However, the licensee did not perform all the required AMP inspections within the period specified in the renewed CoC license Condition 5.iii and VSC's Final Safety Analysis Report (FSAR) as updated. The licensee had up to 2 years to complete the inspections after the effective date of the CoC renewal, which was September 20, 2017, or within 1 year of the 20th anniversary of the first cask loaded at the site, whichever was later. The licensee loaded the first VSC-24 cask on December 12, 1996. Therefore, the last day to implement the AMP inspections was September 20, 2019.
Following the missed AMP inspections, the licensee submitted an exemption from the regulations delineated in 10 CFR 72.212(b)(3), 10 CFR 72.212(b)(5)(i), and 10 CFR 212(b)(11) to provide additional time to perform the required AMP inspections including the lead cask inspection. The licensee proposed to conduct the missed AMP inspections within the next 6 months and concluded that nothing significant would be expected since aging is a long-term degradation issue. The NRC technical staff reviewed and assessed the information presented within the exemption request and found the information acceptable to conduct the AMP inspection within the next 6 months. The technical reviewers and inspectors determined that the risk would be extremely low because of the continuous monitoring of the storage casks and the results of previous aging management inspections conducted at two other sites, which identified no major issues on the VSC-24 storage system. Based on the NRCs technical review of the exemption request, the inspectors decided to treat this issue like a missed technical specification surveillance, which generally allows up to 25 percent additional time to perform and complete a missed surveillance. This issue was determined to constitute a violation of minor significance that is not subject to enforcement action in accordance with Section 2.2.2.e. of the Enforcement Policy.
The licensee completed the remaining AMP inspections during the final week in March 2020 and presented the results of the inspection to the inspection staff in April 2020. The results of the AMP inspections did not show any major degradation of the selected VSC-24 storage systems located on the site.
INSPECTION RESULTS
Failure to Properly Evaluate Design Change to Emergency Diesel Generator Day Tank Level Control and Indication Cornerstone Significance Cross-Cutting Report Aspect Section Mitigating Green None 71111.15 Systems NCV 05000368/2020003-01 Open/Closed The inspectors identified a Green finding and associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion III, Design Control, for the failure to appropriately verify the adequacy of a design change made in 1997 for safety-related emergency diesel generator fuel oil day tank transfer components. Specifically, the licensee failed to properly evaluate the electrical and thermal loads within the enclosures, resulting in a reasonable doubt with respect to the qualification of the day tank level control electronics to be able to operate in the environment of the enclosures.
Description:
On January 15, 2020, the inspectors noted that there appeared to be no cooling air flow through the electrical enclosures containing the day tank level control and indication systems for both Unit 2 emergency diesel generators. These enclosures contain the power supplies and electronic equipment needed to detect the diesel fuel oil level in the day tanks, to actuate the fuel transfer components to add fuel to the day tanks, and to provide alarms to the control room if an abnormal condition was detected. Based on the inspectors questioning, the licensee wrote Condition Report (CR) CR-ANO-2-2020-00100 to document that an air filter on the emergency diesel generator A equipment box was dirty.
Subsequently, the licensee wrote Condition Report CR-ANO-2-2020-00117 to document that the cooling fan on the emergency diesel generator B enclosure was not running.
Maintenance performed every 2 years (Work Order (WO) 52743222 and WO 52751639 in 2018) required that the enclosure ventilation filter be cleaned; however, it implied that one filter exists on each enclosure when there are actually two. The site engineering department evaluated the heat load and electrical power load for the control enclosures and identified that the original (1997) engineering evaluation had errors. The actual electrical and thermal loads were significantly higher than the original analysis. Measurements and analyses performed in July 2020 had significant uncertainty and did not support the original engineering evaluation that no cooling air flow was needed. The inspectors questioned the data and the site responded with additional measurements and analyses (with minimal uncertainty) in September 2020 that demonstrated a maximum estimated enclosure temperature that would be below the 140 °F design limit of the limiting internal components. The estimated enclosure electrical heat load started with the original analysis of ~5.5 Watts (W), increased to the July estimate of ~72 W and ended with the September value of ~43 W. The final information does support that forced cooling is not needed to maintain the electronic components within their design specifications.
Corrective Actions: The licensee replaced all enclosure filters in both emergency diesel generators fuel oil transfer electronic enclosures and replaced the cooling fan in the train B emergency diesel generator enclosure to resolve the immediate air flow issues. The bottom (inlet) filters on the enclosures were cleaned in January 2020 and then documented in July 2020 as being dirty again. A corrective action was proposed to increase the preventive maintenance frequency to semiannual for these filters. A procedure improvement form was also submitted to improve the preventive maintenance and to clearly indicate that two filters are present on each enclosure.
Corrective Action References: Condition Reports CR-ANO-2-2020-00100, CR-ANO-2-2020-00101, CR-ANO-2-2020-00117, CR-ANO-2-2020-00560, CR-ANO-2-2020-02904, CR-ANO-2-2020-02921, CR-ANO-2-2020-02924, CR-ANO-2-2020-02971, and CR-ANO-2-2020-03036
Performance Assessment:
Performance Deficiency: The licensee failed to appropriately verify the adequacy of a design change made in 1997 for safety-related emergency diesel generator fuel oil day tank transfer components.
Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the equipment performance 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 errors were such that there was a reasonable doubt as to the qualification of the day tank level control electronics to be able to operate in the environment of the enclosures. The licensee performed new types of evaluations to reach the final conclusion that the enclosure components would remain within their design criteria.
Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors determined that the finding had very low safety significance (Green) because the finding did not involve the design or qualification of a mitigating structure, system, or component, did not represent a loss of system or function, did not represent an actually loss of function of at least a single train or two separate safety systems, and did not represent an actual loss of function of one or more nontechnical specification trains of equipment designated as high safety significance in accordance with the licensees maintenance rule program.
Cross-Cutting Aspect: None. No cross-cutting aspect was assigned because this deficiency occurred in 1997 and is not indicative of current licensee performance.
Enforcement:
Violation: Title 10 CFR Part 50, Appendix B, Criterion III, Design Control, requires, in part, that design control measures shall provide for verifying or checking the adequacy of design, such as by the performance of design reviews, by the use of alternate or simplified calculational methods, or by the performance of a suitable testing program. Contrary to the above, the licensee did not appropriately verify the adequacy of the design change made in 1997 for safety-related fuel oil transfer components located in the emergency diesel generator day tank level control enclosures by the performance of design reviews, by the use of alternate or simplified calculational methods, or by the performance of a suitable testing program.
Specifically, the licensee failed to provide adequate design evaluations for the electrical and thermal loads within the day tank level control enclosures. Documentation that supported qualification of the day tank level control and indication components was not adequately developed to assure that the components would be capable of performing their functions correctly during a design basis event.
Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
