LANT SYSTEM.5

3/4.7.9 SEALE0 SCURCE CCNTAMINATICN The limitaticns en removable centaminat cn for sources repuiring 4

leak testing, including alpha emitters, is based en 10 CFR 7C.39(c) limits fcr plut nium.

This limitation will ensure that leakage frcm bycreduct, scurce, and special nuclear material sources will not exceed allcwable intake values.

3/A.7.10 FIRE SUPPRESSICN SYSTEMS The OFERASILITY of the fire supcressica systems ensures that adecuate fire suppression capability is available to confine and extin-guish fires cccuring in any certion of the facility where safety related ecuipment is located.

The fire suporession system consists of the water system, spray and/cr sprinklers, Halen and fire hose stations.

The collective capability of the fire sucpression systems is adecuate to minimize patential damage to safety related equipment and is a major element in the facility fire protection program.

Any two of th.e four main fire pumcs provide ccmbined capacity greater than 3575 gpm.

[

In the event that portions of the fire suporession systems are ir.ccerable, alternate backup fire fignt ng e;uipment is recuired to be i

made available in the affected areas un I the affected ecuipment can be restcred to service.

In the event that the fire sucpression water system beccmes inoper-able, immediate corrective measures must be taken since this system provides the major fire suppression cacacility of the plant.

The recuire-ment for a Scecial Recort to the Comnissicn crovides for timely evaluation of the accectability of the corrective measures to provide adequate fire suc;ression capability for the centinued ccera:icn of the nuclear plant.
