• ?LANT SYSiE:*1S SA SES 3/4.7.5 FLOOD PROTECTION The limitation on flood protection ensures that facility protective acti ans wi 11 be taken and opera ti on wi 11 be terminated in the e'len t of flood conditions. The limit of elevation 10.S' Mean Sea Level is oased on the elevation above which facility flood control measures are to provide protection to safety related equipment.

3/4.7.6 CONTROL ROOM EMERGENCY AIR CONDITIONING SYSi~~

The OPERABILITY of the control room emergency air conditioning sys':e~

nsures that 1) the ambient air temperature does not exceed the allowabie temperature for continuous duty rating for the equipment and instrumentation cooled by this system and 2) the control room will remain habitable for operations ersonnel durin and followin all credible accident conditions.

e PERABILITY of this system in conjunction w1t centre 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 SO. ANSI N510-191i -sl!lould :ie *Js&d as a procedural guideline for surveillance testing.

3/4.7.7 AUXILIARY BUILDING EX~AUST 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 art 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. ANSI NSl0-1975 shouiJ :e used as a procedural guideline for surveillance testing

• 3/4. 7 .8 SEALED SOURCE CONTAMINATION The limitations on removable contamination for sources requiring leak testing, including alpha emitters, is basl<:I on 10 CFR 70.39(c) limits for plutonium. This limitation will ensur-9 that leakage from byproduct, source, and special nuclear material sources will not exceed allowable intake values.

The OPERABILITY of this system is demonstrated by irradiating each detector used and normalizing its respective output.

For the purpose of measuring FQ(Z) or FM~M' a full incore flux map is used.

Quarter-core flux maps, as defined in WCAP-8648, June 1976, may be used in recalibration of the excore neutron flux detection system, and full incore flux maps or symmetric incore thimbles may be used for monitoring the QUADRANT POWER TILT RATIO when one Power Range Channel is inoperable.

) The OPERABILITY of t:he control room emergency air conditioning syst:em LC~elC& ~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. p (l7 The OPERABILITY o t s system n con unct on w t control room esign fl 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 N.516-1'75 and Genetic Letter 83-13 3/4. 7.7 AUXILIARY BUILDING EXttAUST AIR FILIB.ATION SYSTEM The OPERABILITY of the auxiliary building exhaust air filtration system ensures that radioactive materials leaking from the ECCS equipment following a 1 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. ANSI N510-l975 and Generic Letter 83-13 should-be used as procedural guidelines for surveillance testing.

3/4.7.8 SEALED SOURCE CONTN1INATION 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 noc exceed allowable intake values.

Sealed sources are classified into three groups according ~o cheir use, with surveillance requirements commensurate with the probability of damage co a soufce in thac group. Those sources which are frequently handled are required to Se cesced more often than those which are not. Sealed sources which are continuously enclosed within a shielded mechanism (i.e., sealed sources within radiation monicoring or boron measuring devices) are considered to be stored and need not be cested unless they are removed from the shielded mechanism.
