Dresden-2 Startup - Bypassing of Containment Pressure Suppression Function

On November 10, 2003, the plant was in startup mode. After completing the Unit 2 Refueling Outage 18 (D2R18), control room operators determined that both the torus and drywell purge valves were simultaneously left open, thus directly connecting the torus air space to the drywell. This bypassed the pressure suppression function of the torus water and put the unit in an unanalyzed condition. The containment pressure suppression function is credited in the loss-of-coolant accident analysis to limit drywell pressure. It accomplishes this by condensing steam from the drywell as it passes through torus water. Control room operators immediately restored proper valve alignment. The licensee reported the incident to the Nuclear Regulatory Commission (NRC), performed a prompt investigation, and implemented interim corrective actions. A more in depth root cause evaluation will be conducted by the licensee. The NRC resident inspectors are following the licenseeÕs root cause determination and corrective action.
