OTHER ACTIVITIES
4OA1 Performance Indicator (PI) Verification
a. Inspection Scope
The inspectors sampled licensee data to confirm the accuracy of reported PI data for the following nine PIs. To determine the accuracy of the report PI elements, the reviewed data was assessed against PI definitions and guidance contained in Nuclear Energy Institute 99-02, Regulatory Assessment Indicator Guideline, Revision 6. Documents reviewed are listed in the Attachment.
Cornerstone: Initiating Events
- Unplanned Scrams per 7000 Critical Hours (3 units)
- Unplanned Scrams with Complications (3 units)
- Unplanned Power Changes per 7000 Critical Hours (3 units)
For the period of April 1, 2014, through March 31, 2015, the inspectors reviewed operating logs, train unavailability data, maintenance records, maintenance rule data, PIPs, consolidated derivation entry reports, and system health reports to verify the accuracy of the PI data reported for each PI.
b. Findings
No findings were identified.
4OA2 Problem Identification and Resolution
.1 Daily Screening of Corrective Action Reports
a. Inspection Scope
In accordance with Inspection Procedure 71152, "Identification and Resolution of Problems," and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed daily screening of items entered into the licensee's CAP. This review was accomplished by reviewing copies of PIPs, attending daily screening meetings, and accessing the licensee's computerized database.
b. Findings
No findings were identified.
.2 In Depth Review
a. Inspection Scope
In addition to the routine review, the inspectors selected the one issue listed below for a more in-depth review. The inspectors considered the following during the review of the licensee's actions: 1) complete and accurate identification of the problem in a timely manner; 2) evaluation and disposition of operability/reportability issues; 3) consideration of extent of condition, generic implications, common cause, and previous occurrences; 4) classification and prioritization of the resolution of the problem; 5) identification of root and contributing causes of the problem; 6) identification of problem identification reports; and 7) completion of corrective actions in a timely manner. Documents reviewed are listed in the attachment.
- PIP-O-14-07055, Priority 3 actions are being used as the sole means to resolve some conditions adverse to quality (CAQs) in the corrective action program which are considered actions outside the corrective action program b. Observations
NRC inspectors discovered PIP-O-14-07055 written by the Oconee Nuclear Oversight group to document potential corrective actions taken outside the corrective action program which created a programmatic vulnerability with respect to assuring full compliance with 10 CFR 50 Appendix B, Criterion XVI. The inspectors noted the corrective action document identified the increased risk of the condition not being corrected in a timely manner, or at all, since the administrative controls, formality, and rigor applied to Priority 3 actions are significantly less than those applied to Priority 2 corrective actions. The licensee identified 112 conditions adverse to quality PIPs written over a period of time from January 1, 2012 until June 23, 2014 that may have been inappropriately closed using solely Priority 3 actions contrary to the guidance of Duke Energy fleet procedure NSD 208, "Corrective Action Program." The licensee performed a review of these 112 PIPs and determined that the vast majority of PIPs had actions
performed correctly (albeit with Priority 3 classifications) or could have been classified as a condition not adverse to quality and thus did not require any Priority 2 actions. The inspectors reviewed a sampling of this population of PIPs and determined the licensee had appropriately dispositioned the Priority 3 actions. Thus, the inspectors discovered that the issue was with the improper classification of the corrective action rather than improper corrective actions to address the adverse condition.
4OA6 Management Meetings (Including Exit Meeting)
Exit Meeting Summary
On April 16, 2015, the resident inspectors presented the inspection results to Mr. Scott Batson, Site Vice President and members of licensee management. The inspectors verified that no proprietary information was retained by the inspectors or documented in this report.
