Cnisn i: Cata; cry a classificatirn of reactor coolant syster tributary situnn tii' be entended only to the first normally closed valve or the f i ng valve ccpuble of rc=ote closurc fron the control roor for the purpose of seismic reevaluation. Seismic qualificatinn of one valve ersures tha: the rcactor conlant pressure boundary (P.CPB) till be raintained in the event of a seismic event which potentially f ails nen-category A equipment. a The Pressurizer Relief Tank (P3,T) was designcted as Seisnic Category A in the crdginal plant design. However, faijure of this tank would not conrtitute a significant hazard to the public health and safety. Therefore. consirtent with Regulatory Guide 1.29, the PRT will not ce designated as Seisnic Category A for the purposes of seistic reevalua:icn. 3. The majority of thu Cherical and Volute Contro3 Systen (CVCS) was designated as Scienic Category A in the plant design. SRC Regulatory Guide 1.29 suggests that the boron addition portion of the CVCS should be Seirsic Category 1. Eowever, at San Onofre Unit l~ calf a limited portion of the CVCS is required for boren injection. Specifically, boron injection enn be ef f ected by the charging purp(s) taking sucticn frem the refueling unter storage tank (EWST) and injecting thrcugh the reactor coolant pt p seals. Therefore, for the purpcse of seistic reevalv: tion enly those compenents and associated piping and va ves recesscry fer berca injection,will be designated as Seismic Category A. 4. The E.ercency Core Cool'.ng Syster (ECOS) was designated as Scismic Categon A in the plant design and is designated as Seisr.ic Category I (T in "LC L -:M story Guide 1.29. 1:cuever, since it is latenced that the ECFB eill be reevaluated to withstand the design basis earthquake (DE E), a L2E vill not cause a LOCA; therefore, the probacility of a LOCA coincident with a DEE is extrenely remote'. In view of this low prooabiltty, only those portiens of the ECCS utilized for 'coron addition (see Ucce 3) will be designated as Seistic Category A f or the purposes of seist.ic reevaluation. In particular, the following systens will not be destpnated as Scism.ic Categery.. Safety Injection Systen (except RWST), Containment Strar Systat, Chemical Addition Systet, Recirculation System, and Cantainacnt Isolation System. 5. Ecgulatorv Guide 1.29 indientes Lhat the Spent ruel Storage Pool Cooling Systet should bc dcsignated as Seismic Category 1. Hcuaver, in the event that cooling is lost to the arent fuel pool, there is considerable tima bef ore the wctcr in the pool begins to boil of f and still mor2 time before sufficient water boils off so as to uncover the spent fuel. This nJ1ows the opcrators considerable time to initiate corrective trea s urea to make up the water ia the f uel storage pool with available onsite and offuite sources. Ther fere, the spent fuel pool cooliag systcc. will not be designated et Sciaric Category A for the p'.trpose of scist it reavaluatien. Of course, the spent fuel pocl itscif will be decignated as Sciente Category A. 940 00

. 6. The Residual Heat Renoval (RHR) System was designated as Seismic Category A in the ori;inal plant dcaign and is designated as Seismic Category I in :;RC Regulatory Guide 1.29. However, the RHR system is only required to briag the plant to a cold shutdown condition. The plant can be brought to cafe hot shutdcun condition and naintained in thi condition indefinitely without the RHR system. In view of this carability the RHR system will not be designated as Scismic Category A for the purpose of seismic reevaluation. 7. The cecponent cooling vater system and saltwater cooling system were denignatec as Seistic Category A in the original plant design. However, for the purpose of seismic reevaluation only thoce portions of these systems which are required to support other seisnic category A systens "ill be designated as Seiscic Category A. The only such equipment rc the charging pu=p oil coolers and the reactor coolant pu=p :ner=al barrier cooling. 8. The waste gas decay tanks were designated as Seismic Category A in the original plant design and the retainder of the gaseous and liquid radwaste systens uere designated as Seisnic Category 3.

However, a fcilure er rupture of any of the cceponents in these systens will not constitute a significant' ha:ard to the health cad safety of the p ublic. Therefore., the gaseous and liqcid reducate systers will not be designated as Seismic Category A for the purpose of seisnic raevaluation.
