SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Grand Gulf Nuclear Station, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information. A licensee-identified, non-cited violation is documented in report Section 71124.0

List of Findings and Violations

No findings or violations of more than minor significance were identified.

Additional Tracking Items

None.

PLANT STATUS

Grand Gulf Nuclear Station, Unit 1, began this inspection period at 83 percent power. On November 6, 2020, a reactor scram occurred from 84 percent power following a sensed low primary water system coolant flow. This system provides cooling to components related to the main generator. Following modifications to the primary coolant flow instrument sensing lines and turbine control valve actuators, the unit was restarted on November 29, 2020. During startup, operators shutdown the plant from approximately 0 percent power on November 30, 2020, to conduct repairs on a condensate booster min flow valve, which had failed. Following repairs, the unit was restarted on December 2, 2020, and reached 98 percent power on December 6, 2020. On December 7, 2020, reactor power was reduced to 70 percent power for a rod pattern adjustment. On December 11, 2020, a reactor scram occurred following a low water level in the primary water system tank. The unit was restarted on December 12, 2020, following modifications to the primary water system. The unit was returned to 100 percent power on December 17, 2020, where it remained at or near 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/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 Disease 2019 (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; conducted plant status activities as described in IMC 2515, Appendix D, Plant Status; 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

Licensee-Identified Non-Cited Violation 71124.08 This violation of very low safety significance was identified by the licensee and has been entered into the licensee corrective action program and is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Violation: Technical Specification 5.4.1(a) requires, in part, that written procedures shall be implemented covering applicable procedures recommended in Regulatory Guide 1.33, "Quality Assurance Program Requirements (Operation)," Revision 2, Appendix A, February 1978. Section 7(e) of Regulatory Guide 1.33 covers Radiation Protection Procedures.

Contrary to the above, on April 24, 2020, the licensee failed to implement written procedures for radiation protection when they free released a temporary chiller with detectable radioactivity from the protected area, and subsequently shipped it offsite to a vendor without proper radiological controls. Specifically, the licensee failed to implement requirements in licensee Procedure EN-RP-121, "Radioactive Material Control," Revision 16.

On April 24, 2020, two temporary chillers that were used during the licensee's refueling outage activities were shipped offsite without proper surveys conducted by radiation protection (RP) staff. One of those temporary chillers, the larger one, contained detectable levels of radioactivity. The temporary chiller was previously identified as having detectable radioactivity via chemistry samples performed on April 8, 2020. These water samples were verified on April 17, 2020, and again, determined there were detectable amounts of radioactivity. At that time, RP staff instructed that labeling be placed on the system plant chillers and supportive equipment, but staff failed to complete these requirements.

Consequently, the equipment was not labeled as, "Potentially contaminated - Contact RP prior to breaching the system," before being stored away for any further use and to establish appropriate radiological controls. When the temporary plant chillers were shipped offsite, RP staff were not contacted and did not survey and frisk the temporary chillers prior to leaving the site. This resulted in free release of radioactive material from the licensee's protected area into the public domain.

Five days later, on April 29, 2020, RP staff discovered that the temporary chillers used to supplement the plant chill water system during the outage were no longer at the licensee's site when they questioned their location. RP staff understood that chemistry samples and surveys previously taken on these chillers identified low trace amounts (but detectable) of radioactivity, with contact dose rates of 0.1 millirem per hour; therefore, they immediately became concerned that the temporary chillers were not controlled as radioactive material.

They soon confirmed these two chillers were shipped offsite without appropriate radiological controls, as required.

Procedure EN-RP-121, "Radioactive Material Control," Revision 16, states, in part, the following:

  • Section 5.2.1.1 - Items indicating the presence of radioactive material, other than naturally occurring, MUST be labeled in accordance with this procedure.
  • Section 5.6.1 - For "Control and Release of Material," items may be considered for free release as long as ALL of the following criteria are met:

No detectable fixed activity above background, other than naturally occurring isotopes

No detectable loose surface contamination

No detectable/suspected internal contamination

No detectable alpha contamination

No radioactive labels or markings

  • Section 5.9.1 - All materials leaving the protected area through the sally port may be evaluated prior to being removed from the protected area by completion of

12.

12 to Procedure EN-RP-121 essentially requires the licensee to evaluate/survey radioactive material prior to release, as authorized by RP staff.

Thus, the licensee failed to follow multiple procedural requirements when they did not label the radioactive temporary chiller, control it as radioactive material, failed to contact RP staff to evaluate/survey the temporary chiller prior to leaving the site, and free released it from the protected area. Upon discovery, the licensee conducted radiological surveys of the plant chiller system equipment and appropriately implemented radiological controls. The licensee identified 500 corrected counts per minute of fixed internal contamination on the larger temporary chiller that was free released offsite to a vendor.

As immediate corrective actions, the licensee contacted the vendor to which the uncontrolled material was delivered and sent a licensee representative to retrieve the items, conducted surveys of the plant chiller system, and reviewed and updated their procedures to enhance the requirements.

Using NRC Inspection Manual Chapter 0612, Appendix E, "Examples of Minor Issues," the inspectors determined that the performance deficiency was more than minor because it was similar to Example 6.a, in which the licensee failed to survey the radioactive material, as required, resulting in a failure to adequately control the release of radioactive material from the site.

Significance/Severity: Green. The inspectors determined that the finding was of very low safety significance (Green) because although it involved a failure in radioactive materials control and was transported from the site, surface contamination levels were less than 5 times any limits and there was no radiation exposure above 1 percent of any occupational or public dose limit (less than

.005 rem).

Corrective Action References: Condition Report CR-GGNS-2020-05694

Observation: Semiannual Trend Review 71152 Through a review of recent issues documented in the licensees corrective action program, the inspectors noted a potential trend related to less than thorough troubleshooting practices at the site. The inspectors noted that these practices unnecessarily challenged plant staff in responding to multiple equipment issues. The following examples demonstrate this potential trend:

1. In the summer of 2020, the licensee wrote multiple condition reports detailing failures of

the control room air conditioner compressor B (Condition Reports CR-GGNS-2020-08197 and CR-GGNS-2020-08349), for which the NRC issued a Green, non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, in Integrated Inspection Report 05000416/2020003 (ADAMS Accession No. ML20302A448). The inspectors found, in this instance, that a failure to adequately troubleshoot the direct cause of the compressor trip such that there was high confidence that the direct cause of the trip was identified and corrected prior to returning it to service, led to the licensee declaring the component operable when it, in fact, would not have met safety function requirements as evidenced by its subsequent failure a day later.

2. As documented in Integrated Inspection Report 05000416/2019004 (ADAMS Accession

No. ML20044F733), the inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, when the licensee failed to correct a condition adverse to quality related to the 208-foot elevation containment airlock door. Specifically, the inspectors identified that Condition Reports CR-GGNS-2016-03721, CR-GGNS-2018-02927, CR-GGNS-2018-03251, CR-GGNS-2018-03261, CR-GGNS-2018-07849, CR-GGNS-2018-08613, and CR-GGNS-2019-03109 were all closed with less than thorough troubleshooting. This lack of effective troubleshooting allowed the underlying condition to go undiagnosed and unresolved as described in the violation.

3. In 2020, the inspectors identified eight condition reports (Condition Reports

CR-GGNS-2020-00872, CR-GGNS-2020-04116, CR-GGNS-2020-05780, CR-GGNS-2020-05784, CR-GGNS-2020-06048, CR-GGNS-2020-07317, CR-GGNS-2020-08156, CR-GGNS-2020-08734) detailing failures/issues of security Door OC708. In most of these condition reports, an issue was identified with the door handle sticking or otherwise not working properly causing the door to not secure properly. In Condition Report CR-GGNS-2020-08754, the inspectors identified potential issues with long-standing degradation of this security door. As evidenced by the repetitive failures of this door, it appears that less than thorough troubleshooting practices for correcting the cause has led to continual challenges.

4. Condition Reports CR-GGNS-2020-09739, CR-GGNS-2020-09756, and

CR-GGNS-2020-09797 document an issue with reactor recirculation flow control valve A unexpectedly changing position. The licensees initial troubleshooting led them to believe there was an issue with the position indicator on the valve itself. Upon replacement of the position indicator, the licensee continued to observe issues with the flow controller. The licensee replaced another component within the control system, which appeared to have corrected the subsequent issue; however, while monitoring system response, the licensee observed continued issues with the controller necessitating additional troubleshooting and corrective maintenance.

5. Condition Reports CR-GGNS-2020-05268, CR-GGNS-2020-05270,

CR-GGNS-2020-05404, CR-GGNS-2020-05405, and CR-GGNS-2020-05427 document an issue with the standby gas treatment system drawdown surveillance not meeting acceptance criteria. While the licensees initial troubleshooting did identify leaking door seals and drains between rooms that could have contributed to the failed drawdown test, it did not identify the direct cause of the failure, which was containment configuration during this surveillance test.

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

  • On November 19, 2020, the inspectors presented the emergency preparedness program inspection technical debrief inspection results to Mr. M. Lewis, Manager, Emergency Preparedness, and other members of the licensee staff.
  • On November 19, 2020, the inspectors presented the public radiation safety inspection results to Mr. R. Franssen, Site Vice President, and other members of the licensee staff.
  • On December 16, 2020, the inspectors presented the emergency preparedness program inspection telephonic exit inspection results to Mr. B. Wertz, General Manager of Plant Operations and other members of the licensee staff.
  • On January 13, 2021, the inspectors presented the integrated inspection results to Mr. R. Franssen, Site Vice President, and other members of the licensee staff.

THIRD PARTY REVIEWS The inspectors reviewed the most recently issued Institute of Nuclear Power Operations report during the inspection period.
