IDENTIFICATION OF OCCURRENCE:

Two Inoperable ECCS Subsystems CONDITIONS PRIOR TO OCCURRENCE: L--- .*.,

Operational Mode 3 DESCRIPTION OF OCCURRENCE:

During heatup of the reactor* coolant system, in accordance with OI I-3.2, Cold Shutdown to Hot Standby, it was discovered that the unit had entered Mode 3 with both safety injection pumps and one centrifugal charging pump inoperable. The unit entered Mode 3 at 1305 hours0.0151 days <br />0.363 hours <br />0.00216 weeks <br />4.965525e-4 months <br /> and this event was discovered a~ 1515 hours0.0175 days <br />0.421 hours <br />0.0025 weeks <br />5.764575e-4 months <br />. The Operating Engineer who had discovered this event during a review of plant status, immediately notified the Shift Supervisor. This violation exceeded LCO 3.5.2 and reliance upon LCO 3.0.3 was required. However, the plant was in Hot Standby at the time and both SI. pumps and the centrifugal charging pump were made operable within the 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> allowed by.LCO 3.0.3. At 1630 hours0.0189 days <br />0.453 hours <br />0.0027 weeks <br />6.20215e-4 months <br />, all action statements were terminated.

DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:

OI I-3.6, Hot Standby to Cold Shutdown, require the clearing of both safety injection pumps and one centrifugal charging pump for over-pressure control. OI I-3.2, Cold Shutdown to Hot Standby, removes the tags from both SI pumps and the charging pump, prior to exceeding 350°F.

The required steps in OI I-3.2 were not performed. The cause of this event was perso~nel er~or.

ANALYSIS OF OCCURRENCE:

Technical Specification 3.0.3 requires that the unit be placed in Hot Standby within one (1) hour and in Cold Shutdown within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />, when conditions in excess of those addressed in the Technical Specifications exist. Both Safety Injection Pumps and the one (1) Cen-trifugal Charging Pump were operable within one . hour and 15 minutes from the discovery of this event. The limiting condition for operation was not violated. At no time was there any danger to the health and safety of the general public or site personnel .
