P..30 PURGE - PURGING PURGE or PURGING is the controlled process of discharging air or gas from a confinement to maintain temperature, pressure, humidity, concentration or other operating condition, in such a manner that replacement air or gas is required to purify the confinement.

1.31 VENTING VENTING is the controlled process of discharging air or gas from a confinement to maintain temperature, pressure, humidity, concentration or other operating condition, in such a manner that replacement air or gas is not provided or required during VENTING. Vent, used in system names, does not imply a VENTING process.

1.32 SITE BOUNDARY The SITE BOUNDARY shall be that line beyond which the land is neither owned, leased nor otherwise controlled by the licensee.

1.33 UNRESTRICTED AREA An UNRESTRICTED AREA shall be any area at or beyond the SITE BOUNDARY access to which is not controlled by the licensee for purposes of protection of individuals from exoosure to radiation from radioactive materials, or any area within the SITE BOUNDARY used for residential quarters or for industrial, commercial, institutional and/or recreational purposes.

1.30 %K%!BER($ OF THE PUBLIC MEMBER(S) OF THE PUBLIC shall include all persons who are not occupationally associated with the plant. This category does not include employees of the licensee, its contractors, vendors or members of the Armed Forces using property located within the SITE BOUNDARY. Also excluded from this category are persons who enter the site to service equipment or to make deliveries. This category does include Dersons who use portions of the site for recreational, occupational or other purposes not associated with the olant.

1.35 HEAVY LOADS Any load in excess of the nominal weight of a fuel and control rod assembly and associated handling tool. For the ourpose of this specification, HEAVY LOADS will be defined as loads in excess of 2000 oounds.

1.36 OPERATIONAL hJtODE - SPODE An OPERATIONAL 'V!ODE (i.e., MODE) shall correspond to any one inclusive combination of core reactivity condition, power level, and average reactor coolant temperature soecified in Table 1.1.

1.37 STAGGERED TEST BASIS A STAGGERED TEST BASIS shall consist of:

a. 4 test schedule for ( n) systems, subsystems, trains, or other designated components obtained by dividing the specified test interval into(n) equal subintervals, and

b. -.The testing of one system, subsystem, train, or other designated component at the beginning of each subinterval.

V 4.21 STANDBY FEEDWATER SYSTEM APPLICABILITY: Applies to the periodic surveillance of the STANDBY FEEDWATER SYSTEM.

083ECTIVE: To demonstrate availability of the STANDBY FEEDWATER SYSTEM+.

+NOTE: The standby feedwater'umps are not safety related equioment and do not require plant safety related emergency power sources for availability.

SPECIFICATION: l. The Demineralized Water Storage tank water volume shall be determined to be within limits at least once per 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br />.

2. At least monthly verify the standby feedwater pumps are available by testing in recirculation on a STAGGERED TEST BASIS.

3. During each refueling outage, verify availability of the respective standby feedwater pump by powering from the non-safety grade diesel generators and providing feedwater to the steam generators.

0.21-1 Amendment Nos. and

BASES FQR SURVEILLANCE RE UIRE%IEÃfS STANDBY FEEDWATER SYSTEM Adequate demineralized water for the standby feedwater system will be verified once per 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br />. The Demineralized IVater Storage Tank provides a source of water to several systems and therefore, requires daily verification.

The standby feedwater pumps will be verified available monthly on a STAGGERED TEST BASIS by starting and ooerating them in the recirculation mode typically from their normal power supply. Also, during each unit's refueling outage, the respective standby feedwater pump will be powered from the unit's C bus utilizing Units 1 and 2 non-safety grade diesel generators and flow tested to the nuclear unit's steam generators. Prior to this test, the refueling unit's C bus will be de-energized and the necessary loads will be transferred to the other unit's C bus.

This su'rveillance regimen will thus demonstrate availability of the entire flow path, backup non-safety grade power supply and pimp associated with a unit at least each refueling outage. The pump, motor driver, and normal power supply availability would typically be demonstrated by operation of the pumps in the recirculation mode monthly on a staggered test basis.
