TROJAN-UNIT 1 3/4 8-4
- PLANT SYSTEMS BASES 3/4.7.6 CONTROL RCOM VENT!LATICN SYSTEM The OPERABILITY of the control room ventilation system ensures that
- 1) the ambient air temperature does not exceed the allcaable tem;erature
'or :ontinuous duty rating for tne equipment and instrumentation cooled by this syster, and 2) the control room will remain habitable for operaticns personnel during and following all credible accident ccnditions.
The OPERABILITY of this system in conjunction with co:i'.rol room design pro-visions is based on limiting the radiation exposure to personnel occupying the control room to 5 rem or less wnole body, or its ecuivalent.
This limitation is consisten witn tne requirements of General Design Criteria 19 of Appendix "A",10 CFR 50.
l 3/4.7.7 SEALED SOURCE CONTAMINATION The limitations on sealed scerce 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 source material.
The limitations on'removabit contamination for sources requiring leak testing, including alpha emitters, is base ( ori ;0 CFR 70.39(c) limits for pl utonium.
Leakage of sources excluded from the requ:rements of this specification represent les.s than one max mum permissible body burden for total body irradiction if the source r aterial is inhaled or ingested.
3/4.7.8 FIRE SUPPRESSION SYSTEMS The OPERABIL??V of the fire suppres' ion systems ensures that auequate fire suppression capability is available to confine and extinguish fires occurring in any portion of the facility wnere safet. related equipment is located.
The fire suppression system consists of the water system, sprinklers and fire hose stations.
The :ollective cenability of the fire suppression systems is adequate to mininize potential damage to safety related equipment and is a major element in the facility fire protection program.
In the event that portions of the ' ire suppression systens are inoperable, alternate backup fire fighting equipment is required to be made available in the affected areas ut til tne inoperable ecuipment is restored to service.
TROJAN-UNIT 1 5 3/4 7-5 Amendment No. 72, 26
PLANT SYSTEMS BASES in the event the fire suppression water system beccmes inoperable, immediate corrective measures must be taken since this system provides the major fire suppressicn capability of the plant. The requirement for a twenty-four hour report to the Comissicn provides for prcept evaluation of the acceptability of the corrective measures to provide adequate fire suppressicn capability for the continued protecticn of the nuclear plant.
3/4.7.9 PENETRATION FIRE BARRIERS The functional integrity of the penetration fire barriers ensures that fires will be confined or adequately retarded from spreading to adjacent portions of the facility.
This design feature minimizes the possibility of a single fire rapidly involving several areas of the facility prior to detection and extinguishment.
The penetration fire l
barriers (doors, walls, dampers, and seals) are a passive element in the facility fire protection program and are subject to periodic inspections.
During periods of time when the barriers are not functional, the combustible loading of the safety-related areas dictates the type of temporary protection to be provided.
The ccmbustible loadings for each room in the plant are listed in Table 3-1 of PGE-1012, Trojan Nuclear Plant Fire Protection Review.
Where combustible loadings are considered low (less than or equal to 1 lb/sq ft equivalent wood), credit is allowed for installed detection systems and installation cf temporary fire barriers. Either of these, in addition to an hourly fire patrol, give adequate assurance that a fire could not initiate and propagate Where combustible through the r.onfunctional penetration barrier.
loadings are somewhat greater (greater than I lb/sq ft equivalent wood) either a temporary fire barrier is installed, an installed detection system is pre /ided, and an hourly fire patrol is established, or a continuous fire watch is required.
For either case, the continuous fire watch or the fire watch patrol is required to ta maintained until the barrier is restored to functional status.
3/4.7.10 HYORAULIC SNUBBERS The hydraulic 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 The only snubbers excluded frcm this event 'nitiating dynamic loads.
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.
TROJAN-UNIT 1 B 3/a 7-5 Amendment No. 78, 39
PLANT SYSTEM 5 BASES The inspection frequency ap:licable to snubbers containing seals fabricated from materials which have been demcnstratec ccmpatible with their operating environment is based upon maintaining a constant level of snubber protection.
Therefore, the required inspection interval varies inversely with the observed snubber failures.
The number of inoperable snubbers found during an inspection of these snubters determines the time interval for the next required inspection of these snubbers.
Inspections performed before that interval has ela; sed may be used as a However, tne new reference point to determine the next inspection.
results of such early inspections perfomed before the original recuired time interval has elapsed (nominal time less 25%) may not be used to lengthen the required inspection interval.
Any inspection whose results require a shorter inspection interval will override the previous schedule.
To provide further assurance of snubber reliability, a representa-tive sample of the installed snubbers will be functionally tested during plant shutdowns at 18-month intervals.
These tests will include streking of the snubbers to verify proper piston movement, lock-up and bleed.
observed failures of these sample snubbers will require functional test-ing of additional units. To minimize personnel exposures, snubbers installed in areas which have high radiation fields during shutd:wn or in especially difficult to remove locations may be r spted from these functional testing requirements provided the OPERASILITY of these snubbers was demonstrated during functional testing at either the completion of their fabrication or at a subsequent date.
