PLANT STATUS
Unit 1 and Unit 2 began the inspection period at rated thermal power and remained at or near rated thermal power 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/readingrm/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. From January 1 - March 19, 2020, the inspectors performed plant status activities described in IMC 2515, Appendix D, Plant Status, and conducted routine reviews using IP 71152, Problem Identification and Resolution. 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 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 and during that time conducted plant status activities as described in IMC 2515, Appendix D; and observed risk significant activities when warranted. In addition, resident and regional baseline inspections were evaluated to determine if all or 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 the cases where it was determined the objectives and requirements could not be performed remotely, management elected to postpone and reschedule the inspection to a later date.

INSPECTION RESULTS
Observation: Emergency Diesel Generator Trends 71152 On November 7, 2019, the licensee experienced an unanticipated drop in frequency on the Unit 2 CD emergency diesel generator (EDG) while performing a scheduled performance test. The licensees investigation determined that the cause for the reduction in frequency was binding of the diesels 6F fuel injector. The inspectors were aware of previous issues with fuel injectors on the plants emergency diesels and decided to review the plants experience with the injectors to determine if there existed an adverse trend that should have been investigated by the licensee and was not. The inspectors initially planned on reviewing operating history during the previous six months to a year but determined that it would be appropriate to review several years of experience mainly by reviewing condition reports that detailed issues with the EDGs.
The plant has four EDGs, two per unit, utilizing 12-cylinder Worthington Model SWB-12 diesels. Each cylinder is equipped with a Bendix model FDX-22 high-pressure fuel injection pump connected to a high-pressure fuel line and a high-pressure fuel injection nozzle. The final injection pressure into the diesel cylinder is advertised at about 15,000 psi. That pressure requires tight tolerances in the fuel injection pump (plunger and casing/guide tube)thus necessitating materials that can resist some scoring and fuel that does not contain material that can damage the injector in the tight tolerance areas. Damage in the tight tolerance areas could cause injector jamming with resultant failure to permit fuel injection.
The high pressure also raises the potential for fuel line leaks. The four EDGS are the only machines at the plant that use this model of injector.
In 2017, the licensee was issued non-cited violation 2017001-003 (ADAMS Accession Number ML1712A321) for failure to correct a previously identified configuration issue with the diesel fuel injectors that could and did cause a split in diesel injector fuel lines. The inspectors' review of condition reports since that time did identify a number of minor fuel leaks associated with injectors and their fuel lines. However, while such leaks normally resulted in the EDG being declared inoperable to fix the leaks, the inspectors did not identify any reports documenting leaks of a sufficient magnitude to, by themselves, require declaring the EDG, with the leak, incapable of performing its design function.
The fuel injector failure of November 7 was determined to be from internal scoring of the injector from abrasive particles either left in the injector after manufacture or factory refurbishment or, from particles in the fuel. Similar failures occurred in 2006 and 2016.
Seven fuel injector failures on recently installed new injectors were experienced in 2006. The failures were attributable to foreign material found in the pumps as supplied by the vendor. In 2016 one fuel injector again failed again due to foreign material fouling.
The licensee corrective actions after the 2006 failures was to require the injector pump vendor to implement measures to improve and verify pump and test stand cleanliness during the refurbishment process. After the 2016 failure, the licensee required multiple changes to improve cleanliness at the refurbishment vendors facilities to improve cleanliness and to enhance plant receipt inspections. The licensee also implemented plans to replace 23 installed fuel pumps, which had not been inspected in accordance with latest inspection criteria. The 2019 failure involved a fuel pump that had been refurbished in 2011. At the time of failure that injector had been in service for approximately 210 operating hours including approximately 80 hours9.259259e-4 days <br />0.0222 hours <br />1.322751e-4 weeks <br />3.044e-5 months <br /> in the Unit 2 CD EDG. In response, the licensee accelerated plans to replace the installed fuel pumps that had not been inspected per the revised criteria.
The inspectors, in addition to reviewing condition reports, reviewed the licensees purchase orders that included the licensees requirements for cleanliness during the vendors work on fuel injectors for the Cook plant. From the documents reviewed, the inspectors did not identify an issue with the licensees response to the conditions found or to their specified corrective actions.
Very Low Safety Significance Issue Resolution Process: Lateral Support Bumper Gaps 71152 This issue is a current licensing basis question and inspection effort is being discontinued in accordance with the Very Low Safety Significance Issue Resolution (VLSSIR) process. No further evaluation is required.
Description:
Near the end of the previous Unit 1 refueling outage (RFO), licensee staff identified a lateral shim for reactor coolant pump (RCP) 11 on the grating adjacent to the pump. The licensee could not determine why the shim was not installed. Prior to restart, the licensee corrected the condition and performed additional inspections on lateral shims in Unit 1. This review identified that a shim on RCP 12 was out of tolerance by 1/16-inch.
Westinghouse evaluated the issue and determined that although the out of tolerance condition reduced the overall margin, the condition did not render the reactor coolant system (RCS) incapable of operating in accordance with the current licensing bases. At the time, the licensee planned to inspect Unit 2 to determine whether a similar condition existed during the next RFO scheduled in October 2019. The inspectors reviewed the licensee's condition evaluation, extent of condition, and proposed corrective actions.
During the Unit 2 RFO, the inspectors conducted a walkdown and visual inspection of the lateral supports that could be viewed from normally accessed areas in containment. The licensee performed a similar inspection and also obtained measurements where practical. The largest gap measured was 1-5/8 inches. The inspectors observations are consistent with this measurement.
Licensing Basis: Because the cold gaps exceed the gaps established for normal operating pressure and temperature (NOP/NOT) conditions and will change as RCS temperature changes, the inspectors inquired as to the acceptability of larger gaps at other than NOP/NOT. The licensee stated that the gaps do not represent a safety concern because of available margins and the reduced severity of conditions that could require lateral restraint - specifically loss of coolant accidents (LOCAs) and seismic events. In particular, seismic events generate lateral force well below those experienced during a LOCA. With respect to the current license bases of Donald C. Cook Nuclear Plant, the licensee considers the larger gaps to be within the current licensing basis (CLB) of the facility because they are in accordance with plant design and gaps must exist to allow for thermal expansion and contraction of the RCS. The inspectors noted that regulatory requirements do not limit analysis to NOP/NOT conditions but did not arrive at a conclusion regarding compliance with regulatory or license conditions.
Significance: The inspectors concluded that the existence of larger gaps at other than NOP/NOT is of very low safety significance based on the information provided by the licensee and Westinghouse, coupled with the engineering judgement of NRC staff. The events that could lead to the lateral support bumpers providing mitigation are LOCA and seismic events.
The LOCA has a very low probability of occurrence, with the most severe challenge occurring at NOP/NOT where the bumpers have gaps consistent with the analyzed conditions. At lower temperatures and pressures, the forces would be significantly less. For seismic events, the forces are significantly lower than LOCA forces. In summary, given a low probability of an initiating event, and significantly lower forces when the gaps are larger, the condition is of very low safety significance.
Technical Assistance Request: The inspectors did not enter either the TIA or Technical Assistance Request process. However, the resident staff did request assistance from region based inspectors who contacted the cognizant branch in the Office of Nuclear Reactor Regulation (NRR). The involved staff agreed that the design approach is consistent with standards practices at the time of design. In addition, in the event of a seismic occurrence, existing requirements to inspect piping provide appropriate safeguards to detect seismic induced damaged. Therefore, the condition represents an issue of very low safety significance that does not warrant additional review.

Failure of Source Range Nuclear Instrumentation Resulted in a Condition Prohibited by Technical Specifications Cornerstone Severity Cross-Cutting Aspect Report Section Not Applicable Severity Level IV NCV 05000316/2020001-01 Open/Closed
Not Applicable 71153 A self-revealed Severity Level (SL) IV non-cited violation (NCV) of Technical Specification (TS) Limiting Condition for Operation (LCO) 3.3.1, Reactor Trip System (RTS)
Instrumentation and TS LCO 3.3.8, Boron Dilution Monitoring Instrumentation (BDMI), was identified when it was discovered that one of the two source range neutron detectors was inoperable during reactor startup testing.
Description:
On November 6, 2019, the licensee replaced one of the Unit 2 source range neutron flux detectors, NRI-32, as part of scheduled work during the refueling outage. The NRI-32 was replaced per its scheduled work order and successfully passed its post maintenance test (PMT) and was subsequently declared operable on November 7, 2019. The PMT was done in accordance with procedure 2-IHP-4030-213-229, Nuclear Instrumentation Source Range Channel Operational Test and Calibration, which had been used in the past to successfully test and calibrate detectors following various replacement and maintenance activities. No significant changes to the procedure or the work activities were observed that would affect the validity of the test.
During start up testing at 2102 on November 13, 2019, it was observed that NRI-32 did not respond as expected while the other channel of detection continued to give expected results.
The licensee performed a partial calibration utilizing the same procedure as before, 2-IHP-4030-213-229, and the detector was once again declared operable on November 14, 2019, after successfully completing the procedure. Subsequently, during start up testing, the detector again failed to operate as expected and the licensee fully inserted all rods and opened the reactor trip breakers.
Subsequent testing was able to identify the cause of the failure as a degraded connector.
The licensee swapped the cable to an installed spare, tested the detector again with 2-IHP-4030-213-229, and the detector was returned to operable at 2217 on November 18, 2019.
No further issues were noted with the detector during start up activities.
As a result of the second failure, the licensee undertook a past operability determination evaluation (PODE) and determined that the degraded connector had existed since replacement during the outage. Technical Specification LCO 3.3.1, Reactor Trip System Instrumentation, requires two source range neutron flux trip channels to be operable in Modes 3, 4, and 5 when the rod control system is capable of rod withdrawal, or one or more rods are not fully inserted. Technical Specification LCO 3.3.8, Boron Dilution Monitoring Instrumentation, requires two source range neutron flux monitoring channels to be operable in Modes 3, 4 and 5. The licensee determined these LCOs were not met prior to transitioning to applicable modes. Additionally, the licensee determined that the duration of inoperability exceeded the TS LCO allowed outage times for both of these requirements and generated Licensee Event Report (LER) 05000/316/2020-001-00 for an Operation or Condition Prohibited by TSs in accordance with 10 CFR 50.73(a)(2)(1)(B), and as an event or condition that could have prevented fulfillment of a safety function in accordance with 10 CFR 50.73(a)(2)(v)(A).
Corrective Action References: AR 2019-11394.
Performance Assessment:
The NRC determined this violation was not reasonably foreseeable and preventable by the licensee and therefore is not a performance deficiency. Specifically, the licensee tested the detector following its replacement utilizing procedure 2-IHP-4030-213-229, Nuclear Instrumentation Source Range Channel Operational Test and Calibration, and the detector successfully passed the test. The licensees PODE determined that at low levels of counts the detector behaved correctly. Furthermore the licensee had used this test successfully in the past to restore the detector to operability and there had been no significant changes to conditions to call the adequacy of the test into question.
Enforcement:
Traditional Enforcement is being used to disposition this violation with no associated Reactor Oversight Process performance deficiency, per NRC Memorandum Interim Guidance for Dispositioning Severity Level IV Violations with No Associated Performance Deficiency, dated June 15, 2018 (ADAMS Accession No. ML18158A220). The inspectors assessed the severity of the violation using Section 6.0 of the NRC Enforcement Policy and determined the significance is appropriately characterized as Severity Level IV due to the inappreciable potential safety consequences. As the other channel of detection remained operable during the specified time frame, no loss of safety function occurred, and Donald C. Cook Unit 2 did not enter any unanalyzed conditions.
Violation:
A. Donald C. Cook Unit 2 TS LCO 3.3.1, Reactor Trip System (RTS) Instrumentation, requires two source range neutron flux trip channels to be operable in Modes 3, 4, and 5 when the rod control system is capable of rod withdrawal, or one or more rods are not fully inserted. With one source range neutron flux trip channel inoperable in Modes 3, 4, or 5, the required action is to restore the channel to operable status within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />. If the required action completion time is not met, then the requirement is to immediately take actions to fully insert all rods and to place the rod control system in a condition incapable of rod withdrawal within one hour. Additionally, if two Source Range Neutron Flux Trip Channels are inoperable in Modes 3, 4, or 5, the required action is to immediately open the reactor trip breakers (RTBs).
B. Technical Specification LCO 3.3.8, Boron Dilution Monitoring Instrumentation (BDMI),requires two source range neutron flux monitoring channels to be operable in Modes 3, 4 and 5. When one source range neutron flux monitoring channel is inoperable in Modes 3, 4, or 5, the required action is to restore the channel to operable status within 7 days.
Contrary to the above:
A. Only one source range neutron flux channel was operable due to source range detector, 2-NRI-32, being inoperable beginning with the closing of the RTBs at 0050 on November 13, 2019 and remained as such until the RTBs were re-opened at 1556 on November 15, 2019. This totaled a period of 63 hours7.291667e-4 days <br />0.0175 hours <br />1.041667e-4 weeks <br />2.39715e-5 months <br /> and 6 minutes, longer than the allowed 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
B. Only one source range neutron flux channel was operable due to source range detector, 2-NRI-32, being inoperable beginning with Unit 2s entry into Mode 5 at 0052 on November 5, 2019, until the Unit exited the mode of applicability on at 1017 on November 18, 2019. The total period of 13 days 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> and 25 minutes exceeded the LCO duration of 7 days.
Enforcement Action: This violation is being treated as an non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.
