3.3 EMERGENCY C~RE COO~G SYSTEM Applicability Applies to the operating status of the emergency core cooling system.

Objective To assure operability of equipment required to remove decay heat form the core in either emergency or normal shutdown situations.

Specifications Safety Injection and Shutdown Cooling Systems 3.3.1 The reactor shall not be made critical, except for low-temperature physics tests, unles.s all of the following conditions are met:

a. The SIRW tank contains not less than 250,000 gallons of water with a boron concentration of at least 1720 ppm but not more than 2000 ppm at a temperature not less than 40°F.

b. All four Safety Injection tanks are operable and pressurized to at least 200 psig with a tank liquid level of at least 186 inches (55.5%) and a maximum level of 198 inches (59%) with a boron concentration of at least 1720 ppm but not more than 2000 ppm.*

c. One low-pressure Safety Injection pump is operable on each bus.

d. One high-pressure Safety Injection pump is operable on each bus.

e. Both shutdown heat exchangers and both component cooling.heat*

exchangers are operable.

f. Piping and valves shall be operable to provide two flow paths from the SIRW tank to the primary cooling system.

g. All valves, piping and interlocks associated with the above components and required to function during accident conditions are operable.

h. The Low-Pressure Safety Injection Flow Control Valve CV-3006 shall be opened and disabled (by isolating the air supply) to prevent spurious closure.

i. The Safety Injection bottle motor-operated isolation valuves shall be opened with the electric power supply to the valve motor disconnected.

j-. *The Safety Injection miniflow valves CV-3027 and 3056 shall be opened with HS-3027 *and 3056 positions* to maintain them open.

• For the remainder of cycle 5, Safety Injection tank T-82B is to have a boron concentration greater than or equal to the primary* coolant system boron concentration, but not to exceed 2000 ppm.
