'PLANT SYSTEMS BASES 3 4.7.5 CONTROL ROOM EMERGENCY VENTILATION SYSTEM The OPERABILITY of the control room emergency ventilation system ensures that
- 1) the ambient air temperature does not exceed the allowable temperature for continuous duty rating for the equipment and instrumentation cooled by this system and 2) the control room will remain habitable for operations personnel during and following all credible accident conditions.
The OPERABILITY of this system in conjunction with control room design provisions is based on limiting the radiation exposure to personnel occupying the control room to 5 rem or less whole body, or its equivalent.
This limitation is consistent with the requirements of General Design Criterion 19 of Appendix "A", 10 CFR 50.
3 4.7.6 ESF VENTILATION SYSTEM The OPERABILITY of the ESF ventilation system ensures that adequate cooling is provided for ECCS equipment and that radioactive materials leaking from the ECCS equipment within the pump rooms following a LOCA are filtered prior to reaching the environment.
The operation of this system and the resultant effect on offsite dosage calculations were assumed in the accident analyses.
The 1980 version of ANSI N510 is used as a testing guide.
This standard, however, is intended to be rigorously applied only to systems which, unlike the ESF ventilation system, are designed to ANSI N509 standards.
For the specific case of the air-aerosol mixing uniformity test required by ANSI N510 as a prerequisite to in-place leak testing of charcoal and HEPA filters, the air-aerosol uniform mixing test acceptance criteria were not rigorously met.
For this reason, a statistical correction factor will be applied to applicable surveillance test results where required.
3 4.7.7 SEALED SOURCE CONTAMINATION The limitations on sealed source removable contamination ensure that the total body or individual organ irradiation does not exceed allowable limits in the event of ingestion or inhalation of the probable leakage from the source material.
The limitations on removable contamination for sources requiring leak testing, including alpha emitters, are based on 10 CFR 70.39(c) limits for plutonium.
Quantities of interest to this specification which are exempt from the leakage testing are consistent with the criteria of 10 CFR Parts 30.11-20 and 70.19.
Leakage from sources excluded from the requirements of this specification is not
~
likely to represent more than one maximum permissible body burden for total body irradiation if the source material is inhaled or ingested.
3 4.7.8 HYDRAULIC SNUBBERS All snubbers are required OPERABLE to ensure that the structural integrity of the reactor coolant system and all other safety related systems is maintained during and following a seismic or other event initiating dynamic loads.
Snubbers excluded from this inspection program are those installed on nonsafety-related systems and then only if their failure or failure of the system on which they are installed, would have no adverse affect on any safety-related system.

. 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 re eased from the rupture of an irradiated fuel assembly.
The minimum ware:
depth is consistent with the assumptions of the accident analysis.
Vater level above the vessel flange in MODE 6 will vary as the reactor vessel head and the system internals are removed.
The 23 feet of water are required before any subsequent movement of fuel assemblies or control rods.
3 4.9.12 STORAGE POOL VENTILATION SYSTEM The limitations on the storage pool ventilation system ensure that all radioactive material released from an irradiated fuel assembly will be filtered through the HEPA filters and charcoal adsorber prior to discharge to the atmosphere.
The OPERABILITY of this system and the resulting iodine removal capacity are consistent with the assumptions of the accident analyses.
The 1980 version of ANSI N510 is used as a testing guide.
This standard, ho~ever, is intended to be rigorously applied only to systems which, unlike the storage pool ventilation system, are designed to ANSI N509 standards.
For the specific case of the air-aerosol mixing uniformity test required by ANSI N510 as a prerequisite to in-place leak testing of charcoal and HEPA filters, the air-aerosol uniform mixing test acceptance criteria were not rigorously met.
For this reason, a statistical correction factor will be applied to applicable surveillance test results where required.
In order to maintain the minimum negative pressure required by Technical Specifications (1/8 inch V.G.) during movement of fuel within the storage pool or during crane operation with loads over the pool, the crane bay roll-up door and the drumming room roll-up door, located on the 609-foot elevation of the auxiliary building, must be closed.
- However, they may be opened during these operations under administrative control. If the crane bay door needs to be opened during fuel movement, an example of an administrative control might be tt> station an individual at the door who would be in communication with personnel in the spent fuel pool area and could open the door when passage was completed or in the event of an emergency.
For the drumming room door, an example of an administrative control might be to require the door to be reclosed after normal ingress and egress of personnel or material, or to station an individual at the door if the door needs to remain open for an extended. period of time..
Should the doors become blocked or stuck open while under administrative control, Technical Specification requirements will not be considered to be violated provided the Action Statement requirements of Specification 3.9.12 are expeditiously followed, i.e.,
movement of fuel within the storage pool or crane operation with loads over the pool is expeditiously suspended.

REFUELING OPERATIONS BASES 3 4,9. 13 SPENT FUEL CASK MOVEMENT The limitations of this specification ensure that, during insertion or removal of spent fuel casks from the spent fuel pool, fuel cask movement will be constrained to the path and liftheight assumed in the Cask Drop Protection System safety analysis.
Restricting the spent fuel cask movement within these requirements provides protection for the spent fuel pool and stored fuel from the effects of a fuel cask drop accident.
3 4.9.14 SPENT FUEL CASK DROP PROTECTION SYSTEM The limitations on the use of spent fuel casks weighing in excess of 110 tons (nominal) provide assurance that the spent fuel pool would not be damaged by a dropped fuel cask since this weight is consistent with the assumptions used in the safety analysis for the performance of the Cask Drop Protection System.

The operation of this system and the resultant effect on offsite dosage calculations were assumed in the acciden" analyses.
The 1980 version of ANSI N510 is used as a testing guide.
This standard.
however, is intended to be rigorously applied only to systems which, unlike the ESF ventilation system, are designed to ANSI N509 standards.
For the specific case of the air-aerosol mixing uniformity test required by ANSI N510 as a prerequisite to in-place leak testing of charcoal and HEPA filters, the air-aerosol uniform mixing test acceptance criteria were not rigorously met.
For this reason, a statistical correction factor will be applied to applicable surveillance test results where required.
3 4 7.7 HYDRAULIC SNUBBERS All snubbers are required OPERABLE to ensure that the structural integrity of the reactor coolant system and all other safety related systems is maintained during and following a seismic or other event initiating dynamic loads.
Snubbers excluded from this inspection program are those installed on nonsafety-related systems and then only if their failure, or failure of the
,system on which they are installed, would have no adverse effect on any safety-related system.
The visual inspection frequency is based upon maintaining a constant level of snubber protection to systems.
Therefore, the required inspection interval varies inversely with the observed snubber failures and is determined by the number of inoperable snubbers found during an inspection.
Inspections performed before that interval has elapsed may be used as a new reference point to determine the next inspection.
However, the results of such early inspections performed before the original required time interval has elapsed (nominal time less 25%)
may not be used to lengthen the required inspection interval.'ny inspection
'whose results required a shorter inspection interval will override the previous schedule.
When the cause of the rejection of a snubber is clearly established and remedied for that snubber and for any other snubbers that may be generically susceptible, and verified by inservice functional testing, that snubber may be exempted from being counted as inoperable.
Generically susceptible snubbers are those which are of a -specific make or model and have the same design features directly related to rejection of the snubber by visual inspection, o'
are simi,larly located or exposed to the same environmental conditions such as temperature, radiation, and vibration.

PLANT SYSTEMS BASES When a snubber is found inoperable, an engineering evaluation is performed, in addition to the determination of the snubber mode of failure, in order to determine if any safety-related component or system has been adversely affected by the inoperability of the snubber.
The engineering evaluation shall determine whether or not the snubber mode of failure has imparted a significant effect or degradation on the supported component or system.
To provide assurance of snubber functional reliability, a representative sample of the installed snubbers will be functionally tested during plant shutdowns at 18-month intervals.
Observed failures of these sample snubbers shall require functional testing of additional units.
The service life of a snubber is evaluated via manufacturer's input and information through consideration of the snubber service conditions and associated installation and maintenance records (newly installed snubber, seal replaced, spring replaced, in high radiation area, in high temperature area, etc...).
The requirement to monitor the snubber service life is included to insure that the snubbers periodically undergo a performance evaluation in view of their age and operating conditions.
These records will provide statistical bases for future consideration of snubber service life.
The requirements for the maintenance of records and the snubber service life review are not intended to affect plant operation.
The number of snubbers to be functionally tested during each surveillance is based on calculations performed to allow extension of the surveillance interval from 18-months to 24-months, and therefore, the number of snubbers functionally tested deviates from the number required by the Westinghouse Standard Technical Specifications (NUREG-0452, Revision 4).
3 4.7.8 SEALED SOURCE CONTAMINATION The limitations on removable contamination for sources requiring leak testing, including alpha emitters, are based on 10 CFR 70.39(c) limits for plutonium.
These limitations ensure that leakage from byproduct,
- source, and special nuclear material sources will not exceed allowable intake values.
3 4.7.9 FIRE SUPPRESSION SYSTEMS The OPERABILITY of the fire suppression systems ensures that adequate fire suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety related equipment is located.
The fire suppression system consists of the water system, spray and/or sprinklers,
- Co2, Halon and fire hose stations.
The collective capability of the fire suppression systems is adequate to minimize potential damage to safety related equipment and is a major element in the facility fire protection program.
In the event that one or more of the required low pressure C02 systems are isolated for personnel protection, to permit entry for routine tours, maintenance, construction or surveillance testing, the fire detection system(s) required by specification 3.3.3.8 shall be verified to be operable and a Roving Fire Watch Patrol established in the affected areas not occupied by workers.
The Roving Fire Watch Patrol(s) shall consist of one or more persons knowledgeable of the location and operation of the fire fighting equipment and good fire protection/personnel safety practices such as maintenance of access and egress routes and personnel accountability measures.
The functions of the Roving Fire Watch Patrol can be fulfilled by personnel involved in D.

REACTOR VESSEL AND STORAGE POOL The restrictions on minimum water level ensure that sufficien" 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 accident analysis.
Water level above the vessel flange in MODE 6 will vary as the reactor vessel head and the system internals are removed.
The 23 feet of water are required before any subsequent movement of fuel assemblies or control rods.

The 1980 version of ANSI N510 is used as a testing guide.
This standard, however, is intended to be rigorously applied only to systems which, unlike the storage pool ventilation system, are designed to ANSI N509 standards.
For the specific case of the air-aerosol mixing uniformity test required by ANSI N510 as a prerequisite to in-place leak testing of charcoal and HEPA filters, the air-aerosol uniform mixing test acceptance criteria were not rigorously met.
For this reason, a statistical correction factor will be applied to applicable surveillance test results where required.
In order to maintain the minimum negative pressure required by Technical Specifications (1/8 inch W.G.) during movement of fuel within the storage pool or during crane operation with loads over the pool, the crane bay roll-up door and the drumming room roll-up door, located on the 609-foot elevation of the auxiliary building, must be closed.
- However, they may be opened during these op'erations under administrative control. If the crane bay door needs to be 'opened during fuel movement, an example of an administrative control might be to station an individual at the door who would be in communication with personnel in the spent fuel pool area and could open the door when passage was completed or in the event of an emergency.
For the drumming room door, an example of an administrative control might be to require the door to be reclosed after normal ingress and egress of personnel or material, or to station an individual at, the door if the door needs to remain open for an extended period of time.

movement of fuel within the storage pool or crane operation with loads over the pool is expeditiously suspended.
3 4.9.13 SPENT FUEL CASK MOVEMENT The limitations of this specification ensure that, during insertion or removal of spent fuel casks from the spent fuel pool, fuel cask moveme'nt will be constrained to the path and liftheight assumed in the Cask Drop Protection System safety analysis.
Restricting the spent fuel cask movement within these requirements provides protection for the spent fuel pool and stored fuel from the effects of a fuel cask drop accident.
3 4.9.14 SPENT FUEL CASK DROP PROTECTION SYSTEM The limitations on the use of spent fuel casks weighing in excess of 110 tons (nominal) provide assurance that the spent fuel pool would not be damaged by a dropped fuel cask since this weight is consistent with the assumptions used in the safety analysis for the performance of the Cask Drop Protection System.
