| Title | Unit 1 Reactor Coolant System Pressurizer Pressure Boundary Leakage |
| Description | The inspectors determined that additional inspection was required for the inactive leak on the heater sleeve penetration in the pressurizer bottom head. Technical Specifications 3.4.13 RCS Operational Leakage, states that RCS operational leakage shall be limited to no pressure boundary leakage in Modes 1 through 4. Contrary to this requirement, on February 25, 2008, Constellation identified RCS deposits indicated that the sleeve welds had been leaking during the previous operating cycle. The penetration sleeves are part of the RCS pressure boundary. The leak was discovered during scheduled visual examination of the pressurizer head penetration area. Constellation entered this issue into their CAP (CR IRE-029-507) to complete a cause analysis and reportability review. An unresolved item (URI) has been opened to track this issue pending review of Constellations evaluation to determine if a performance deficiency exists. (URI 05000317/2008002-01.
