| Title | Failure to Control, Calibrate and Evaluate M&TE |
| Description | An NRC-identified NCV of 10 CFR 50, Appendix B, Criterion XII, Control of Measuring and Test Equipment, occurred when PPL failed to control and calibrate measuring and test equipment (M&TE) at specified periods and document evaluations of missing M&TE. The inspectors added significant value in identifying, that since at least 2008, when M&TE was missing for long periods of time after being due for calibrations, it was not being captured and evaluated in CRs in a timely manner once retired and declared lost. PPL entered this issue into their CAP as CR 1339535. The issue was evaluated in accordance with IMC 0612 Appendix E, Examples of Minor Issues, and determined to be similar to examples 3J, 3K and 4A. Namely, a finding was more than minor if significant programmatic deficiencies were identified that could lead to worse errors if uncorrected (3J, 3K) and the licensee routinely failed to perform evaluations (4A). Specifically, overdue or missing M&TE were not being evaluated for their associated impact on the validity of past work in the CAP program since at least 2008 and that evaluations when performed did not meet the requirements of NDAP-QA- 0515, Control and Calibration of Plant Measuring and Test Equipment, Revisions 3 and 4. The finding affected the equipment performance attribute of the Mitigating Systems cornerstone and its objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the control, calibration, and adjustment of M&TE on a periodic basis ensures that work results achieved on safety-related equipment are within specifications and standards. The finding was evaluated using IMC 0609, Attachment 4, Phase I - Initial Screening and Characterization of Findings. The finding screened to Green since it was not a design or qualification deficiency, not a loss of system safety function, or risk significant due to external events. The NCV was determined to have a cross-cutting aspect in Problem Identification and Resolution, CAP - Evaluation of Identified Problems area. Namely, problems are thoroughly evaluated such that resolutions address causes and extent of conditions and evaluate CAQs for operability. Specifically, PPL did not thoroughly evaluate problems to include the individual missing M&TE, the overall programmatic recurrence, and the potential effects on operability of safety related equipment. |
