Found the NRC inspection reports leading up to this.[1]<p><i>Significance: P (pending)</i><p><i>Jun 30, 2023</i><p><i>Identified By: SR</i><p><i>Item Type: AV Apparent Violation (AV)</i><p><i>Failure to Identify and Correct a Condition Adverse to Quality Associated with the EDG Fuel Oil System</i><p><i>A self-revealed finding with significance to be determined (Pending) and associated AV of Title of the Code of Federal Regulations (10 CFR) Part 50, Appendix B, Criterion XVI, "Corrective Action," was identified when the licensee failed to identify and correct a condition adverse to quality for the EDG fuel oil system that left the system vulnerable to premature piping cracks and eventually resulted in the failure of the ‘A’ EDG during testing on November 2, 2022. Specifically, inspectors determined that, based on the failure history of the EDGs and the licensee’s documented conclusions that attributed pipe cracks to prior maintenance events, the licensee had sufficient information to identify the existence of a condition adverse to quality related to the design of the EDG fuel oil system. This condition caused threaded fuel oil piping connections to be vulnerable to maintenance activities that over torqued, strained, or impacted the piping. Despite the challenge to maintain leak-tight connections and repeat occurrences of cracked piping, no significant changes were made to maintenance practices, procedures or system design, and the licensee continued to reactively monitor for leakage even after vulnerabilities were identified.</i><p>Previous report:<p><i>Significance: W (white)</i><p><i>Mar 31, 2022</i><p><i>Identified By: NRCI</i><p><i>Item Type: NOV Notice of Violation (NOV)</i><p><i>Failure to Correct Condition Adverse to Quality Resulting in Inoperable Emergency Diesel Generator</i><p><i>An NRC-identified apparent violation of 10 CFR 50, Appendix B, Criterion XVI, was identified for the licensee failing to correct a condition adverse to quality resulting in the inoperability of the 'B' emergency diesel generator (EDG). Specifically, there were indications of erratic governor performance following the January 2022 maintenance package that were identified during testing January 16, 2022. The governor performance was also erratic during the February 9, 2022, surveillance test, after which the licensee declared the EDG inoperable. As a result of this condition, the ‘B’ EDG was inoperable for a time in excess of its technical specification (TS) allowed outage time.</i><p>The scale is Green, White, Yellow, Red. Normal is green. This problem reached White in March 2022, and the June 2023 problem shows as Pending, which means the NRC had not assigned a color level yet. Now they have escalated that to Yellow, according to the press coverage. Which is a good move, considering that troubles have been observed in both the A and B emergency generator systems. Anyone know if they have more than two emergency generators? Two is kind of low.<p>[1] <a href="https://www.nrc.gov/docs/ML2322/ML23223A006.pdf" rel="nofollow noreferrer">https://www.nrc.gov/docs/ML2322/ML23223A006.pdf</a>
