SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a biennial problem identification and resolution inspection at the Callaway Plant 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.

List of Findings and Violations No findings or violations of more than minor significance were identified during the inspection.

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.

OTHER ACTIVITIES - BASELINE

71152Problem Identification and Resolution Biennial Inspection

The inspectors performed a biennial assessment of the licensees corrective action program, use of operating experience, self-assessments and audits, and safety-conscious work environment. The assessment is documented below.

(1) Corrective Action Program Effectiveness: Problem Identification, Prioritization, Evaluation, and Corrective Actions - The inspection team reviewed the stations corrective action program and the stations implementation of the program to evaluate its effectiveness in identifying, prioritizing, evaluating, and correcting problems, and to confirm that the station was complying with NRC regulations and licensee standards.

The sample included approximately 220 condition reports and 50 jobs (work orders).

This included an in-depth 5-year review of condition reports associated with the essential service water and ultimate heat sink systems.

(2) Operating Experience, Self-Assessments, and Audits - The team evaluated the stations processes for use of industry and NRC operating experience. The team also evaluated the effectiveness of the stations audits and self-assessments program. The sample included 26 industry operating experience communications and associated site evaluations.

(3) Safety-Conscious Work Environment - The team evaluated the stations safety-conscious work environment. The team interviewed station personnel and the employee concerns program manager. The team reviewed selected case files from the employee concerns program and sampled condition reports that had been anonymously submitted.

The sample included focus group interviews with approximately 40 individuals from 5 different working groups (engineering, fix-it-now, operations, mechanical maintenance, nuclear oversight, and security) and a review of the most recent safety culture survey.

Corrective Action Program Effectiveness Observation 71152Problem Identification and Resolution Effectiveness of Problem Identification: Overall, the team found that the licensee was identifying and documenting problems at an appropriately low threshold. During the 2-year assessment period, the licensee initiated slightly more than 14,000 condition reports.

However, the team did identify a few performance deficiencies that were administrative in nature that were not more-than-minor associated with problem identification. Specifically, during a review of 50 work orders, the team identified two examples where the licensee had documented issues in the work orders that were not captured in condition reports. In a third example, the team noted the licensee identified a condition that should have also been documented in a condition report, but failed to generate a condition report in a timely manner.

Each of these issues had been adequately addressed prior to the teams identification through the work order process. The team did not consider these examples to be indicative of a programmatic issue within the area of problem identification.

Effectiveness of Prioritization and Evaluation of Issues: Overall, the team found that the licensee was appropriately classifying and prioritizing conditions in accordance with established procedures. Of the 14,000 condition reports written during the assessment period, approximately 40 percent were classified as adverse conditions and handled accordingly. The team found that, where the corrective action procedure would have allowed a condition to be classified or prioritized at a lower level, the licensee typically classified issues at the higher level and took more conservative actions in developing cause evaluations. While most of the condition reports that the team reviewed were appropriately characterized as Adverse, the team identified a few examples where the condition reports were not classified correctly. For example, the team identified an example where the licensee had failed to classify a condition report associated with an NRC non-cited violation for a simulator fidelity issue as an adverse condition in accordance with their procedure. This error appeared to be caused by the timing of the finding because the issue was initially raised as a question which was appropriately documented as an Other Issue condition report and the licensee failed to upgrade or write a new condition report when it became clear that the issue represented a performance deficiency. In another example, the team found that the licensee had inappropriately classified a condition report as Other Issue to document the failure to implement an alternate method of shutting the equipment hatch because of an interference issue. Since the action to implement an alternate method of shutting the hatch was a corrective action for an adverse condition report, the condition report documenting the failure should have also been an adverse condition report. The handling of these condition reports as Other Issues did not adversely affect the corrective actions nor timeliness.

Effectiveness of Corrective Actions: Overall, the team concluded that the licensee identified effective corrective actions for the problems evaluated in the corrective action program. The licensee implemented these corrective actions in a timely manner, commensurate with their safety significance, and reviewed the effectiveness of the corrective actions appropriately.

However, a Notice of Violation issued during the assessment period indicates that continued diligence by the licensee was necessary in the area of corrective actions. This Notice of Violation was issued for the licensees failure to develop and implement adequate corrective actions associated for a failure previously identified by the NRC in 2014 to test engineered safety feature transformers load tap changer response times (05000483/2017007-01).

Corrective Action Program Assessment: Based on the samples reviewed, the team determined the licensees corrective action program complied with regulatory requirements and self-imposed standards, and the licensees implementation of the corrective action program adequately supported nuclear safety. The team found that managements oversight of the corrective action program process was effective. Corrective action program meetings (screening, leadership, and corrective action review board) thoroughly reviewed each condition report, and demonstrated that the members were properly prepared and engaged with the process.

Operating Experience, Self-Assessments, and Audits Observation 71152Problem Identification and Resolution Based on the samples reviewed, the team determined the licensee appropriately evaluated industry operating experience for its relevance to the facility. Operating experience information was incorporated into plant procedures and processes as appropriate.

The team further determined the licensee appropriately evaluated industry-operating experience when performing root cause analysis and apparent cause evaluations. The licensee appropriately incorporated both internal and external operating experience into lessons learned for training and pre-job briefs.

The team found that one of the strengths of the licensees corrective action program was associated with their willingness to be self-critical as evidenced in the thorough nature of their self-assessments and audits. The team found numerous examples of findings identified by the licensee and documented in the corrective action program including: overdue action items, trend for untimely updates to calculations, failure to perform a Part 21 evaluation for an Allen Bradley relay failure, and control building heating ventilation and air conditioning system pressure controllers being placed in manual without declaring the system to be inoperable.

The NRC reviewed these issues and determined them to be not more-than-minor in significance.

Safety-Conscious Work Environment Observation 71152Problem Identification and Resolution Based on interviews with plant staff and reviews of the latest safety culture survey results to assess the safety-conscious work environment, the team determined the licensee had established and maintained a healthy safety-conscious work environment. Employees appeared willing to raise nuclear safety concerns through at least one of the several means available. All of those interviewed had an adequate knowledge of the corrective action program process and would initiate a condition report, or work with someone who would do so on their behalf, if they knew of a safety concern.

A potential vulnerability was identified during the interviews associated with the licensees corrective action program system database interface. The licensee had replaced their in-house developed system with an externally developed system in September 2016 which was the subject of many focus group interviews. The new system did not perform all of the functions of the in-house developed system and was generally disliked by front-line individuals. Most individuals expressed difficulty in searching the database. Some members of one work group indicated that they believed they were expected to search the database prior to initiating a condition report, making it difficult to initiate a condition report. These individuals indicated they had raised safety concerns, and would continue to do so, either through the condition reporting process or through their chain-of-command. The team found that while the expressed difficulties with the user interface did not appear to have impacted the safety-conscious work environment, it represented an area where continued licensee management attention was warranted.

All plant personnel were aware of the Employee Concerns Program and most were willing to use it as an alternate avenue to raise concerns if required.

EXIT MEETINGS AND DEBRIEFS

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

On April 12, 2018, the inspectors presented the biennial problem identification and resolution inspection results to Mr. T. Herrmann, Site Vice President, and other members of the licensee staff.
