| Title | Failure to Include Unit 2 Service Water Pump Supports in the ASME Code Section XI Inservice Inspection Program |
| Description | The team identified a Green finding and an associated non-cited violation of 10 CFR 50.55a(g)(4) for the licensees failure to inspect Unit 2 service water pump supports in accordance with ASME Code Section XI. Specifically, the licensee failed to include Unit 2 service water pump supports in the Inservice Inspection Program and had not completed a visual VT-3 examination since the supports were installed in 1991. The licensees corrective actions included incorporating the supports into the Unit 2 Inservice Inspection Program, performing an immediate operability determination, assigning a corrective action to determine the past operability, and documenting the issue in the corrective action program as condition reports CR-ANO-2-2016-00361 and CR-ANO-2-2016-00421. The failure to inspect the Unit 2 service water pump supports in accordance with ASME Code Section XI was a performance deficiency. The performance deficiency was determined to be more than minor because it was associated with the design control attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to periodically inspect the pump supports could result in the failure to identify a nonfunctional support that would increase the risk of a pump failure. The finding was evaluated using Inspection Manual Chapter 0609, Significance Determination Process, Attachment 0609.04, Initial Characterization of Findings, and Appendix A, The Significance Determination Process (SDP) for Findings At-Power, Exhibit 2 Mitigating Systems Screening Questions, dated June 19, 2012. The team determined the finding was of very low safety significance (Green) because the finding was a deficiency affecting the design or qualification of a mitigating system, structure or component, but the system, structure or component maintained its operability. The team did not identify a cross-cutting aspect for this issue because the cause of this performance deficiency was not reflective of current performance. |
