PLANT STATUS
Callaway Plant began the inspection period at rated thermal power. On April 4, 2020, the unit automatically tripped on low steam generator water level due to a controller failure for a feedwater control valve. After replacing the failed controller and other similar controllers for the feedwater control valves, the licensee commenced a reactor startup on April 6, 2020. The licensee returned to rated thermal power on April 8 2020, 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/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 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; observed risk significant activities; and completed onsite 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
Observation: Semiannual Trend Review 71152 The inspectors reviewed the licensees corrective action program, performance indicators, system health reports, and other documentation to identify trends that might indicate the existence of a more significant safety issue for the following system: safety-related heating, ventilation, and air conditioning (HVAC).
As part of the cause evaluation for the issue described in Licensee Event Report (LER) 05000483/2020-001-00, Emergency Exhaust Train Inoperable Due to Fan Belt Degradation and Failure, (ADAMS Accession Number ML20108F546), the licensee performed an extent of condition review. This involved scheduling jobs to look at all 29 safety-related HVAC components that use fan belts. The job tasks included checking for belt tension, material condition, fan performance, and replacing belts as needed. The licensee placed a high priority on these tasks, starting the work in February 2020, and completing approximately 40 percent of the inspections by the end of May 2020. Although the scope and prioritization of the inspections were appropriate, the licensee encountered several types of issues during this work. The licensees inspections to-date identified the following:
- Five fans were found with out-of-specification belt tension
- Three belts were installed after they had exceeded the recommended shelf life
- Two belts had been installed using an outdated revision of the work instructions
- Eight components were found to have out-of-specification fan speed
- One of the installation work orders failed to take as-found data before replacing/tensioning the fan belt
Note that these results were not yet complete, but reflect the information available at the time of inspection. With the exception of the original emergency exhaust fan belt failure, none of the above issues resulted in an inoperability of the associated systems.
The examples of not completing the job to the correct revision represent gaps in coordination and planning for corrective actions. Similarly, the example of not taking as-found data represents errors in communication and results in missing data that is used in past operability assessments. The examples of installing a belt that has exceeded its shelf life, as-found belt tension being out of tolerance, and identifying fans that are outside their design for speed represent gaps in maintaining design control that the station was not sensitive to prior to the emergency exhaust fan belt failure. Specifically, the licensee was not aware of vendor information and operating experience at other stations, such that Callaway was not appropriately monitoring shelf life for belts, had been using an improper installation method that could damage the belts, and was not establishing the correct belt tension.
Condition Report 202002488 for the residual heat removal A room cooler (SGL10A) is of particular interest. When the belt inspection was completed using the incorrect revision of the job, the belts were improperly installed by rolling on under tension instead of after fan disassembly with minimal tension. This recreated a condition that the licensee was attempting to correct via this job. The licensee identified this issue through their post-work interviews, wrote the condition report, assessed operability, and scheduled the work to be done again correctly.
The licensee created several roll-up condition reports to capture the above issues. For example, Condition Report 202002763 describes the failure to collect data, inadequate communication, and a lack of a questioning attitude while performing these jobs. Condition Report 202002737 describes cross-functional weaknesses in teamwork including preparation, a lack of formality in assigning corrective actions, and not appropriately considering short-term vulnerabilities while performing fan belt work without a complete cause evaluation.
The original root cause, Condition Report 202000878, has also been updated with these issues and corrective actions assigned.
The inspectors acknowledge that the licensee identified the original broken fan belt through operator tours of the plant. Similarly, the issues described above are the results of an extensive and aggressive extent-of-condition and extent-of-cause review process by the licensee.
The inspectors area of concern for safety-related HVAC issues is the gap in knowledge that was available via operating experience and vendor information prior to the failure. Given the number of examples affecting several aspects of safety-related HVAC systems, the inspectors determined that this may be an emerging trend.
Overall, the inspectors concluded that the licensee demonstrated a low threshold for issue identification and documentation in the corrective action program. The licensee applied a risk-based approach to ensure corrective actions were scheduled commensurate with an issues safety significance. The inspectors did not identify any additional trends or concerns that might be indicative of a more significant issue.
Licensee-Identified Non-Cited Violation 71153 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: Callaway Plant Technical Specification 5.4.1, Procedures, requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Revision 2, Appendix A, Section 9, Procedures for Performing Maintenance, states, in part, that maintenance that can affect the performance of safety-related equipment should be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances.
Contrary to the above, from June 25, 2019, to February 18, 2020, the licensee failed to properly preplan and perform maintenance that can affect the performance of safety-related equipment in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances. Specifically, work instructions to install and tension drive belts for safety-related fans were not appropriate to the circumstances because the maintenance instructions failed to incorporate vendor guidance and industry standards intended to ensure proper service life of fan belts. As a result, the licensee improperly installed drive belts in the emergency exhaust system fans by rolling them on under tension, installed belts that had exceeded their shelf life, and did not provide adequate belt tension values including post-run tension checks. These inadequate procedures and instructions for safety-related drive belts resulted in the emergency exhaust fan CGG02B inner belt failing which rendered the train B emergency exhaust system inoperable for several months. This was reported in LER 05000483/2020-001-00, Emergency Exhaust Train Inoperable Due to Fan Belt Degradation and Failure.
Significance/Severity: Green.
Significance: The inspectors determined the finding to be of very low safety significance (Green) because the finding only represented a degradation of the radiological barrier function provided for the auxiliary building and spent fuel building.
