DEFINITIONS SOURCE CHECK 1.33 A SOURCE CHECK shall be the qualitative assessment of channel response when the channel sensor is exposed to a source of increased radioactivity.

STAGGERED TEST BASIS, 1.34 A STAGGERED TEST BASIS shall consist of:

a.

A 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.

THERMAL POWER 1.35 THERMAL POWER shall be the total reactor core heat transfer rate to the reactor coolant.

TRIP ACTUATING DEVICE OPERATIONAL TEST 1.36 A TRIP ACTUATING DEVICE OPERATIONAL TEST shall consist of operating the Trip Actuating Device and verifying OPERABILITY of alarm, interlock and/or trip functions.

The TRIP ACTUATING DEVICE OPERATIONAL TEST shall include adjustment, as necessary, of the Trip Actuating Device such that it actuates at the required Setpoint within the required accuracy.

UNIDENTIFIED LEAKAGE 1.37 UNIDENTIFIED LEAKAGE shall be all leakage which is not IDENTIFIED LEAKAGE or CONTROLLED LEAKAGE.

UNRESTRICTED AREA 1.38 An UNRESTRICTED AREA shall be any area at or beyond the SITE BOUNDARY

.The OPERASILI f he Ann us Ventilation System ensures that during LOCA conditions, contai n vess leakage into the annulus will be filtered through the. HEPA: filters a d.carb adsorber trains prior to discharge to the atmosphere.

Operation of the yst with the heaters operating to maintain low humidity

'using automatR c rol for at least 10Tcontin~uous hours in a 31-day' period is sufficient to reduce the buildup of moisture on the adsorbers and.HEPA filters.

This requirement is necessary to meet the assumptions used in the safety analyses and limit the SITE BOUNDARY radiation doses to within the dose guide-line values of 10 CFR Part 100 during LOCA conditions.

ANSI N510-1980 will be used as a procedural guide for surveillance. testing.

3/4.6.1.9 CONTAINMENT PURGE SYSTEMS The containment purge supply mad exhaust isolation valves for the lower compartment and the upper compartrant (24-inch), and instrument room (12-inch),

and the Hydrogen Purge System (4-inch) are required to be sealed closed during plant operation since these valves have not been demonstrated capable of closing during a LOCA.

Maintaining these valves sealed closed during plant operations ensures that excessive quantities of radioactive materials will not be released via the Containment Purge System.

To provide assurance that these containment valves cannet be inadvertently opened, the valves are sealed closed in accord-ance with Standard Review Plan 6.2.4 which includes mechanical devices.to seal or lock the valve' closed, or prevents power from,being supplied to the valve operator.

The use of the containment purge lines is restricted to the 4-inch Con-tainment Air Release and Addition System valves since, unlike the lower compart-ment and the upper compartment, instrument room, and the Hydrogen Purge System valves, these 4-inch valves are capable of closing during a LOCA.

Therefore, the SITE BOUNDARY dose guideline values of 10 CFR Part 100 would not be exceeced in the event of an accident during containment purging operation.

Operation with the line open will be limited to 2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> during a calendar year for the 4-inch valves.

The total time the containment purge (vent) system isolation valves may be open during MODES 1, 2, 3, and 4 in a calendar year is a function of anticipated need and operating expericnce.

Only safety-related reasons; e.g.,

containment pressure control or the reduction of cirborne radioactivity i

to facilitate personnel access for surveillance and. maintenance activities, may be used to support the additional time requests.

Leakage integrity tests with a maximuni al'owable leakage rate for contain-ment purge supply and exhaust valves will provide early indication of resilient material seal degradation and will allow opportunity for repair before gross leakage failures could develop.

The 0.60 L, leakage limit of Specification 3.6.1.2b. shall not be exceeded when the leakage rates determined by the leakage integrity tests of these valves are added to the previously determined total for all valves and penetrations subject to Type B and C tests.

i 3/4.9 REFUELING OPERATIONS BASES 3/4.9.1 BORON CONCENTRATION The limitations on reactivity conditions.during REFUELING ensure that:

(1) the reactor will remain subcritical during CORE ALTERATIONS, and (2) a j

uniform boron concentration is maintained for reactivity control in the water volume having direct access to the reactor vessel.

These limitations are consistent with the initial conditions assumed for the boron dilution incident in the safety analyses.

The value of 0.95 or less for K includes a-eff 1% Ak/k conservative allowance for uncertainties.

Similarly, the boron concentration value of 2000 ppm or greater includes a conservative uncertainty allowance of 50 ppm boron.

The locking closed of the required valves during refueling operation precludes the possibility of uncontrolled boron dilution of the filled pcrtion of the Reactor Coolant System.

This action prevents flow to the Reactor Coolant System of unborated water by closing flow paths from sources of unborated water.

3/4.9.2 INSTRUMENTATION The OPERABILITY of the Source Range Neutron Flux Monitors and/or the Baron 7 Dilution Mitigation System ensures that redundant monitoring capability is g

available to detect changes in the reactivity condition of the core.

3/4.9.3 DECAY TIi4E The minimum requirement for reactor subcriticality prior to movement of irradiated fuel assemblies in the reactor vessel ensures that sufficient time has elapsed to allow the radioactive decay of the short-lived fission products.

This decay time is consistent with the assumptions used in the safety analyses.

3/4.9.4 CONTAINMENT BUILDING PENETRATIONS Mt The requirements on containment building penetr ion losure and OP BILITY of the Reactor Building Containment Purge System en re tha a relea of radioactive material within containment will be re tricted from age to the environment or filtered through the HEPA filters and ch:m:F sorbers prior to release to the atmosphere.

The OPERABILITY anc closu restrictions are sufficient to restrict radioactive material release rom a fuel element rupture based upon the lack of containment pressurization potential while in the l

REFUELING MODE.

Operation of the Reactor Building Containment Purge System and the resulting iodine removal capacity are consistent with the assumption of the safety analysis.

Operation of the system with the heaters operating to maintain low humidity using automatic control for at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the adsorbers and HEPA filters.

ANSI N510-1980 will be used as a procedural guide for surveillance testing.

REFUELING OPERATIONS JASES 3/4.9.9 and 3/4.9.10 WATER LEVEL - REACTOR VESSEL and STORAGE POOL The restrictions on minimum water level ensure that sufficient water depth is available to remove 99% of the assumed 10% iodine gap activity released from the rupture of an irradiated fuel assembly.

The minimum water depth is consistent with the assumptions of the safety analysis.

3/4.9.11 FUEL HANDLING VENTILATION EXHAUS STEM ac+ia4ed The limitations on the Fuel Handi'n Ventilatic Exhaust System ensure that all radioactive material releas rom an irr lated fuel assemoly will be filtered through the HEPA filters an carbon dsorber prior to discharge to the atmosphere.

Operation of th syste th the heaters operating to_ main-tain low humidity using automatic contro for at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the adsorcers and HEPA filters.

The OPERABILITY of this system and the resulting iodine removal capacity are consistent with the assumptions of the safety analyses.
