PLANT SYSTEMS BASES 3/4.7.5 FLOOD PROTECTION The limitation on flood protection ensures that facility protective actions will be taken and operation will be terminated in the event of flood conditions.

The limit.of elevation 10.5 1 Mean Sea Level is based on the elevation above which facility flood control measures are required to provide protection to safety related equipment.

3/4.7.6 CONTROL ROOM EMERGENCY AIR CONDITIONING SYSTEM The OPERABILITY of the control room emergency air conditioning 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 provi-sions 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~of Appendix~'

3/4.7.8 SEALED SOURCE CONTAMINATION The limitations on removable contamination for sources requiring leak testing, including alpha emitters, is based on 10 CFR 70.39(c) limits for plutonium.

This limitation will ensure that leakage from byproduct, source, and special nuclear material sources will not exceed allowable intake values.

Sealed sources are classified into three groups according to their use, with surveillance requirements co11111ensurate with the probability of damage to a source in that group.

Those sources which are frequently handled are required to be tested more often than those which are not.

Sealed sources which are continuously enclosed within a shielded mechanism (i.e., sealed sources within radiation monitoring or boron measuring devices) are considered to be stored and need not be tested unless they are removed from the shielded mechanism.

BASES 3/4.7.9 SNUBBERS All snubbers art required OPERABLE to ensure that tht 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. Snubbtrs excluded from this inspection program art those installed on nonsafety related systems and then only if thtir failure or failure of the system on which they wtre installtd, would havt no advtrst tffect on any safety-related system.

A list of individual snubbtrs rtquirtd to bt operablt per the technical specifications with dttailtd information of snubber location and sizt and of system affected shall bt available at the plant in accordance with Section 50.7l(c) of 10 CFR Part.50.

The accessibility of each snubber shall be determined and approved by the Station Operations Review Corrmittee.

The determination shall be based on tht existing radiation levels and tht expected time to perform a visual inspection in each snubber location as well as other factors associated with accessibility during plant operations (t.g.,

temperature, atmosphere, location, etc.) and the rec011111endations of Regulatory Guide 8.8 and 8.10. The addition or deletion of any snubber shall be made in accordance with Section 50.59 of 10 CFR Part 50.

The visual inspection frequency is based upon maintaining a constant level of snubber protection to systems. Therefore, the required inspection interval varies inversely with tht observed snubber failures and is dtttrmined by tht number of inoperable snubbers found during an inspection. Inspections performed before that i~terval has elapsed may be used as a new reference point to determine tht next inspection. However, the results of such early inspections performed before tht original required time interval has elapsed (nominal time less 251) may not bt used to lengthen the required inspection interval.

Any inspection whose results rtquirt a shorter inspection interval will override the previous schedule.

When the cause of tht rejection of a snubber is clearly established and remedied for that snubbtr and for any other snubbers that may be generically susceptible, and verified by inservict functional testing, that snubber may be exempted from being counted as, inoperable. Generically susceptible snubbers are those which art of a specific make or model and have the same design features directly related to rejection of the snubber by visual inspection or are similarly located or txpostd to the same environmental conditions, such as temperature, radiation, and.vibration.

When a snubber 1s found inoperable, an engineering evaluation is performed, in addition to the determination of the snubber mode of failure, in order to determine 1f any safety-related component or system has been adversely affected by the inop1rabil1ty 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.

3/4.7.5 FLOOD PROTECTION The limitation on flood protection ensures that facility protective actions will be taken and operation will be terminated in the event of flood conditions. The limit of elevation 10.5' Mean Sea Level is based on the elevation above which facility flood control measures are required to provide protection to safety-related equipment.

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 Part 50. ANSI N510-1975 and Generic Letter 83-13 should be used as procedural guidelines for surveillance testing.

3/4.7.7 AUXILIARY BUILDING EXHAUST AIR FILTRATION SYSTEM The OPERABILITY of the auxiliary building exhaust air filtration system ensures that radioactive materials leaking from the ECCS equipment following a LOCA are filtered prior to reaching the environment. The operation of this system and the resultant effect on offsite dosage calculations was assumed in the accident analyses.

REFUELING OPERATION~

BASES 3/4.9.9 CONTAINMENT PURGE AND PRESSURE-VACUUM RELIEF ISOLATION SYSTEM The OPERABILITY of this system ensures that the containment vent and purge penetrations will be automatically isolated upon detection of high radiation levels within the containment. The OPERABILITY of this system is required to restrict the release of radioactive material from the containment atmosphere to the environment.

3/4.9.10 and 3/4/9/11 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 accident analysis.

3/4.9.12 FUEL HANDLING AREA VENTILATION SYSTEM The limitations on the fuel handling area 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.

ANSI NSl0-1975 and Generic Letter 83-13 should be used as procedural guidelines for surveillance testing.
