HIGH PRESSURE COOLANT INJECTION SYSTEM FAILED SURVEILLANCE TESTING

"On 9/14/05 at 2138, the High Pressure Coolant Injection (HPCl) system was declared inoperable. The HPCI Pump In Service Surveillance Test was in progress with system flow and speed being adjusted to establish surveillance test conditions. Speed and flow oscillations were observed when turbine speed approached 3900 rpm. Since speed and flow oscillations prevented the establishment of surveillance test conditions, HPCI was declared inoperable. Evaluations of these speed and flow oscillations are ongoing.

"Loss of the HPCI is reportable under 10CFR50.72(b)(3)(v) as loss of a single train safety system required to mitigate the consequences of an accident. No additional Emergency Core Cooling Systems or Safety Related equipment was inoperable during this time period."

The licensee notified the NRC Resident Inspector.
