RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Definitions 140 F. Pressure is defined by Specification 3.1.2. A refueling shutdown refers to a shutdown to replace or rearrange all or a portion of the fuel  :

I assemblies and/or control rods.

1.2.7 Refueling Operation )

An operation involving a change in core geometry by manipulation of fuel or control rods when the reactor vessel head is removed.

1.2.8 Refueling Interval

• j I

145x 18 months. l 1.2.9 Startup The reactor shall be considered in the startup mode when the shutdown margin is reduced with the intent of going critical.

1.2.10 Remain Critical ,

1 A technical specification that requires that the reactor shall not remain I critical shall mean that an uninterrupted normal hot shutdown procedure will be completed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

1.2.11 T avg At operating conditions avgT is defined as the arithmetic average of the coolant temperatures in the hot and cold legs of the loop with the greater number of reactor coolant pumps operating, if such a distinction of loops can be made.

l 1.2.12 Heatup - Cooldown Mode The heatup-cooldown mode is t.ie range of reactor coolant temperature greater than 200 F and less than 525 F.

l 1.3 Operable l A component' or system is operable when it is capable of performing its intended function within the required range. The component or system shall be considered to have this capability when: (1) it satisfies the limiting conditions for operation defined in Specification 3, (2) it has been tested periodically in accordance with Specification 4, and has met its performance requirements, (3) the system has available its normal and emergency sources of power, and (4) its required auxiliaries are capable of performing their intended function. When a system or component is determined to be inoperable solely because its normal power source is inoperable or its emergency power source is inoperable, it may be considered OPERABLE for the purpose of satisfying the requirements of its applicable Limiting Condition for Operation provided its redundant system or component is OPERABLE with an OPERABLE normal and emergency power source.

RANCHO SECO UNIT 1 TECHNICAL SPECIFICATIONS Definitions REFUELING INTERVAL 145> .For the following surveillance test, the " refueling interval" shall temporarily be extended to the Cycle 8 refueling outage.

TS Number Description Table 4.1-2 13 Internal Vent Valve Tests t

i This temporary definition of refueling interval shall expire upon startup from 4 the Cycle 8 refueling outage.
