EMERGENCY CORE COOLING SYSTEMS 0

ECCS SUBSYSTEMS - Tavg < 300 F L

LIMITING CONDITION FOR OPERATION i

3.5.3 As a minimum, one ECCS subsystem comprised of the following shall be OPERABLE:

a. One# OPERABLE high-pressure safety injection pump, and

b. An OPERABLE flow path capable of taking suction from the refueling water tank on a Safety Injection Actuation Signal and automatically transferring suction to the containment sump on a Recirculation Actuation Signal.

APPLICABILITY: ' MODES 3* and 4.

ACTIONi

a. With no ECCS subsystem OPERABLE, restore at least one ECCS subsystem to OPERABLE status within I hour or be in COLD SHUTDOWN within the next 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br />,

b. In the event the ECCS is actuated and injects water into the Reactor Coolant System, a Special Report shall be prepared and submitted to the Commission pursuant to Specification 6.9.2 ,

within 90 days describing the circumstances of tb3 actuation and the total accumulated actuation cycles to %e.

SURVEILLANCE RE0VIREMENTS _

i 4.5.3.1 The ECCS subsystem shall be demonstrated OPERABLE per the applicable Surveillance Requirements of 4.5.2.

4.5.3.2 All high pressure safety injection pumps, except the above

. required OPERABLE pump, shall be demonstrated inoperable at least once i per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> 0

whenever the temperature of one or more of the RCS cold legs is 5 275 F by verifying that the motor circuit breakers have been removed from their electrical power supply circuits.

• With pressurizer pressure < 1750 psia.

1. A maximum of one high-pressure safety injection pump shall be OPERABLE whenever the temperature of one or more of the RCS cold legs is s 2750F.

When Tavg s 350 F, the OPERABLE high pressure safety injection pump will be placed in Pull-to-Lock and will not start automatically. Manual use of the high pressure safety injection pump will be conducted in accordance with approved procedures.
