RHR VALVE AUTOMATICALLY WENT CLOSED INSTEAD OF OPEN DURING TESTING
"At 0540 hours CST on 1/9/03 during the performance of QCOS 1000-09 (RHR Power Operated Valve Test), the RHR Injection Valve 2-1001-29A automatically closed upon achieving the full open position. Group II isolation relays for both the 2-1001-29A and 2-1001-29B valves were discovered energized, which would cause these injection valves to close thereby prohibiting the low pressure injection function for both RHR subsystems (note that no Group II isolation signal was present). As such, Technical Specifications 3.5.1 Condition D was entered. The isolation logic relays were reset (deenergized) at 0625 CST and the 2-1001-29A and 2-1001-29B valves were satisfactorily cycled. Technical Specifications 3.5.1 Condition D has been exited. A prompt investigation is in progress.
"The notification is being made in accordance with 10CFR50.72(b)(3)(V)."
The NRC Resident Inspector has been notified.
