Dear Mr. Stello:
Our e>perience in the design and licensing of nu lear pctier plants has indicated a need for more definitive design and c assification criteria for safety related electrical equipment.
JEEE-27 is appropriate for s
electrical equipment used to shutdown the reactor and actuate engineered safety featurcs systems.
However, this IEEE Standard is r.ot easily j
extended to other applications and is overly restrictive cnd costly for some equip:nont that is related to safety only in t secondary nanner, e.n., enoinwnt usert to verifv plant operating conditien prior in 3
th
!:.itr.i;;. af a pc: ttlatcd accidant.
Accordingly, Ucstinghouse has dcVeloped " Criteria for Saicty Related Electrical Equipment for Nuclear Porter Generatin Stations", s;hich is enclosed f or your review and corrment. These cri ria classify elec-trical equipment according to safety classes in ough correspondance 1
to the nachaaical equipment categories of Af!SI-hi8.2-1973, "Huclear Safety Criteria for the Design of Pressurized Unter Reacier "lants".
our irient to apply the enclosed criteria.in the de';i 1 of plants It i::
t i
referenc-ing f.ESAR-41 and RESAR-3 and in all tutt.re applicatt 2nx. To this end, uay we suggest a one day necting with you and/or appropriate m0mbers of your staff the week of July 15 to clarify or othentise discuss these critcria.
Very truly yours i
