EVENT TEXT

| ATMOSHERIC STEAM DUMP VALVE PRESSURE LOCKING CONCERN |
| |
| "At approximately 1600 hours on July 18, 2002, an engineering evaluation |
| concluded that under certain conditions 1MS-156, a manually operated main |
| steam atmospheric dump valve (ADV), could have been susceptible to Pressure |
| Locking which could have prevented the opening of the valve during a |
| postulated event. This notification involves a single unit 1 ADV (1MS-156) |
| on 1 of 2 steam flow paths. Due to a dissimilar valve design, this condition |
| does not affect either the unit 2 or unit 3 ADVs |
| |
| "Research into the condition has determined that 1MS-156 was potentially |
| susceptible to pressure locking during the time of reactor operation, from |
| initial valve installation in November 1997, to when this condition was |
| rectified on July 10, 2002 (by the installation of a pressure relief device |
| on the valve bonnet) . Since the cause of the pressure locking has been |
| fixed, there is no current operability concern. |
| |
| "The ADVs are credited for opening for decay heat removal and cooling down |
| the Reactor Coolant System to reduce pressure. In several event scenarios |
| involving postulated Steam Generator tube leaks, this is desirable in order |
| to minimize offsite dose releases. Failure of 1MS-156 during such an event |
| could increase the time required to achieve cold shutdown (Mode 5) and the |
| postulated off-site doses associated with the accident analysis. However, |
| the analyses for such events (for example, the UFSAR Chapter 15 accident |
| analysis for SG tube rupture) do not assume any failures of the ADVs. |
| |
| "This is a historical condition reportable under 10 CFR 50.72(b) (3) (v) . |
| This regulation requires that an 8-hour ENS report be made of any event or |
| condition that at the time of discovery could have prevented the fulfillment |
| of the safety function of structures or systems that are needed to (A) . |
| Shut down the reactor and maintain it in a safe shutdown condition; (B) |
| Remove residual heat; (C) . Control the release of radioactive material; or |
| (D) - Mitigate the consequences of an accident. |
