| Title | Unusual Event - Loss of Containment Integrity |
| Event Description | During testing, a small crack (3"- 4" axial crack) was identified on a return line to the torus for both HPCI and RCIC (steam driven ECCS systems). The valve upstream of the leak has been closed, however, the leak is still unisolable between that valve and the torus. This plant condition does not threaten public safety.
The licensee notified the NRC Resident Inspector, as well as State and local agencies.
This is a follow up notification to EN 42887. Peach Bottom Atomic Power Station Terminated the Unusual Event at 0513 [EDT] on 10/08/06. Unit 2 is currently shutdown in Mode 4. In Mode 4, Primary Containment is no longer required. The licensee notified the NRC Resident Inspector, State and Local agencies. Notified R1DO (Krohn), R1 (Dapas), NRREO (Quay), NRR (Dyer, Weber), IRD (Blount), DHS (Gray), FEMA (Dunker). |
