| event text = During the performance of planned Unit 2 High Pressure Coolant Injection (HPCI) Logic System Functional Surveillance testing an unexpected condition occurred. It was observed during the HPCI suction swap from the Condensate Storage Tank (CST) to the Torus, that the CST level lowered and the Torus level rose unexpectedly. At that time, the test was aborted and the system was restored to an available status but maintained Tech. Spec. inoperable pending additional evaluation. Following the evaluation, it was determined that the HPCI system Torus suction check valve permitted reverse flow. The HPCI system could not be restored to an operable status and requires additional troubleshooting and maintenance to return to an operable status." | | event text = During the performance of planned Unit 2 High Pressure Coolant Injection (HPCI) Logic System Functional Surveillance testing an unexpected condition occurred.
