- 2. Results and assessment of review of any applicable changes to PIs A three year review by the PI lead did not identify any significant changes to PIs that would result in a reduction or unintended gap in the key safety attributes of each safety cornerstone.
- 3. Results and assessment of review of any applicable changes to Rules and STSs Revisions to rules and Standard Technical Specifications within the last three years did not indicate a need for revision.
- 4. Results and assessment of review of recent Operating Experience Baffel bolts Torus delamination & corrosion (IP 71111.20)
Containment liner corrosion (IP 71111.20)

Title:
Inaccurate Information Provided Regarding N2E Nozzle Weld Overlay
==
Description:==
The NRC identified an VIO of 10 CFR 50.9, "Completeness and Accuracy of Information," for the licensee's failure to provide data to the NRC that was accurate in all material aspects.
Specifically, on two occasions (October 1995, May 2000), the licensee stated that weld 1B31-1RC-12BR-E-5 had been modified with a full-structural weld overlay (FSWOL), when in fact it had only been modified with a less robust design overlay (leak barrier). The NRC approved the licensee's requests/proposed alternatives in part based on the inaccurate characterization of the welds. The licensee has since installed the FSWOL and entered the issue into the corrective action program as CR 10197850. The NRC determined this was a SLIII violation on the basis that had the licensee provided accurate information, it would likely have caused the NRC to reconsider a regulatory position.
- 6. Feedback Forms Open 71111.08-2275 - Relocate 3 gpd SG tube leakage guidance to IMC 2515 App D 71111.08-2294 - Strengthen requirement language for SG Head inspection Closed (Missing & Incomplete Records)
ML17143A017 71111.08-2258 - Improperly closed, no justification or approval on record.
Recommendation to perform an IP 71111.21N type program evaluation for ISI.
Justification was: I agree with the document lead reviewers final determination. The feedback has merit. The feedback is being considered and discussed as part of concurrent efforts in other programmatic areas, e.g., as an element of potential future focus area under IP71111.21N. However, I will add that at this time, given resource limitations and program workload priorities we determined that pursing this feedback/suggestion as a stand-alone initiative is not feasible.
