| Title | Modification Leads to Auxiliary Building Flood Vulnerability |
| Description | A URI was identified by the inspectors for an AB flood scenario created during implementation of the ISFSI modification. On April 30, 2013, the licensee initiated condition report (CR) 13-01917 for water exceeding 17 inches in non-safety electrical manhole (EMH) number 8 as identified by their normal inspection process. On May 6, 2013, the licensee initiated CR- 13-01973 for excessive rain that in combination with a trench previously excavated for a modification associated with the new ISFSI project resulted in water intrusion into the AB and a Hi-Hi alarm on the floor drain tank. The resident inspectors expressed a concern regarding these two events and the licensee took immediate actions to back-fill the section of the trench adjacent to EMH-8. The inspectors also expressed a concern regarding the modification review process which failed to identify the creation of a flood vulnerability for site structures housing safety related components. The licensee subsequently initiated CR-13-02022 to evaluate the modification program for any necessary corrections. Pending completion of additional evaluations in determining the performance deficiency (PD) and associated significance, this is identified as URI 05000395/2013003-01, Modification Leads to Auxiliary Building Flood Vulnerability. |
