| Title | Failure to Identify and Evaluate Class 1 Structural Conditions Adverse to Quality |
| Description | The inspectors identified an NCV of 10 CFR 50 Appendix B Criterion XVI, Corrective Actions, of very low safety significance because NextEra staff did not promptly identify nine visual indications of structural problems representing conditions adverse to quality. These problems were observed by NextEra staff during a maintenance rule (MR) walkdown of the Fuel Storage Building (FSB) on November 20, 2014, and documented in walkdown notes as conditions warranting entry into the corrective action program (CAP). However these problems were not entered into the CAP to identify them as conditions adverse to quality until questioned by the inspectors. NextEra staff took corrective actions to enter the issues into their CAP in AR10206192, AR02016238, AR02016225 and AR020168863 and initiated AR02014116 for not promptly identifying these problems. This performance deficiency was considered to be more than minor because it is associated with the Barrier Integrity Cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events, and affected the attribute of design control structural integrity. Specifically, the inspectors determined the finding was more than minor because four of the conditions exceeded American Concrete Institute (ACI) 349.3R-96 "Tier II structural criteria, which indicated they require further technical evaluation and analysis to validate the existing conditions or repair to preserve structural function. This issue was evaluated in accordance with IMC 0609, Appendix A, The Significance Determination Process for Findings At- Power, Exhibit 3, Barrier Integrity Screening Questions, and screened as very low safety significance (Green) because the observed FSB degradation did not adversely impact structural or radiological barrier functions of the building. This finding is related to the crosscutting area of Human Performance - Procedure Adherence because individuals did not follow CAP process, procedures, and work instructions [H.8]. |
