| Title | Adequacy Of Temporary Containment Penetration Design For Shutdown Operations |
| Description | A URI was identified by the inspectors for an issue of concern associated with adequate design of a temporary containment penetration fixture installed in a spare containment penetration. On October 18, 2012, the inspectors noted that the licensee was using Dow Corning foam as a sealant for a temporary containment penetration fixture installed during the refueling outage to support various work activities within containment. An issue of concern was developed regarding the pressure retention capability of the fixtures design when considering the increase in containment pressure following a loss of the RHR system and other means of core decay heat removal are unavailable. The licensee initiated CR-12-04599 and CR-12-04810 for additional evaluations. Pending completion of evaluations in determining related PDs and their characterization, this issue is identified as URI 05000395/2012005-05, Adequacy of Temporary Containment Penetration Design for Shutdown Operations. |
