TROJAN-UNIT 1 3/4 7-20 Amendment No. 79, ygg,152

j PLANT SYSTEMS BASES -

3/4.7.6 CONTROL ROOM VENTILATION SYSTEM The OPERABILITY of the control room ventilation system ensures that

1) the ambit'.! ei- temperature does.not exceed the allowable temperature for continuaaz * :s rating for the equipment and instrumentation cooled by this system sad 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 pro-visions 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 Criteria 19 of Appendix "A",10 CFR 50. System operability can be affectec by ECCS recirculation leakage and Containment leakage should the conditions assumed in FSAR Section 15.6.5.6 be exceeded.

The OPERABILITY of this system in conjunction with contral room design provisions is also based on limiting the toxic gas exposure to control room personnel consistent with the FSAR design basis and Regulatory Guide 1.95.

Recirculation mode cf operation is defined as operation of the control roem emergency ventilation system with the outside air dampers closed. In the event of a radiation release while operating the system in the recirculation mode of operation, the system is operated in the pressurization mode of operation by opening the outside air dampers. '

Operation of the system in this nenner nwets the intent of this specification and satisfies the FSAR cosign basis and requ?rements of GDC 19.

3/4.7.7 SEALED SOURCE CONTAMINATION The limitations on sealed source removable contamination ensure that the total b*dy or individual organ irradiation does not exceed allowable limits in the esent of ingestion or inhalation of the source material.

The limitations on removable contamination for sources . requiring leak testing, including alpha emitters, is based on 10 CFR 70.39(c) limits for plutonium. Leakege of sources excluded from the requirements of this specification represent less than one maximum permissible body burden

,  ; for total body irradiation if the source material is inhaled or ingested.

3/4.7.8 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, sprinklers 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.

TROJAN-UNIT 1 B 3/4 7-5 Amendment No. 78, 28 ,152

PLANT SYSTEMS BASES (Continued)

In the' event that portions of the fire suppression systems are inoperable, alternate backup fire fighting equipment is required to be made available in the af fected areas until the inoperable equipment is restored to service.
