! The couerission's Men,rendum and Order of May 23,1980 -(CLI-80-21), dimeted i that the staff initiate a rulemaking on the subject of environmental quali- l fication of safety grade electrical.eguipment. We understand that this- s l . activity .will be undertaken by your staff in m,sponse to_the Commissico - .j r

We request that OSD evaluate the advisability of developing in a' broad
- single rulemaking action, an. amendment to.10 CFR 50 which would include. -
- 1) the rulemaking directed b
- of electrical equipment, 2) ythe therulemaking Coom
- 1ssion proposed.in on environmental the Commission qualification paper - l from I&E (SECY-80-319), on independent verification testing and inspection ,
! of equipment's environmental qualiffcations.' and, 3) broadly address the ~
! qualification of both electrical-and mechanical equipment (including chemical.
t process equipment such as hydrogen recoatiners) for seismic and dynamic loading conditions as well as other environmental conditions. The rule should address requirements for opemting as well as neu facilities. We believe that the bryader rule would be of greater benefit to the staff and
.give better guidance to theMedustry. than one that. addresses.a more limited >
scope of equipment qualification. We suggest that the proposed new rule be l
. -in the form of a. nee appendix to 10 CFR Part 56 which refers back to appro T ? ' '
l priate General ~ Besign Criteria in Appendix A. c. , ,

Your evaluation should consider amongr other. issues, the potential .for., expediting i 4
i c
or delaying issuance'of specific portions of ther regulation when promulgated
'separetely, relative to,their being combined in a single broad regulation.

In addition to this' request for a proposed broad rule, we request that it be augumented by Angulatory Guides. A revision of Reg. Guide 1.89 to include the current staff position would probably suffice for electrical equipment qualification. There is so present equivalent gli.do for mechanical equipment, i
hence, this sould be a new but a very important undertaking. We anticipate
! that these two guides would be supplemented as necessary by appropriate i.
supporting guides. -
, c L Since we would not want to delay' unnecessarily.the start of your efforts on
- f portices 1) and 2). me.woeld appreciate receiving your recommendations on CJ this request;by October 1J1980.^;.Thatstaff of .the Assistaat .Mrector.for' _n;-
9leg Meterials and -Qualifications will assist see by prwiding whatewer available', "~/ . .
itafbreation that you desire la daseloping year r-ations. We are aise '
- available to meet with yes and your staff to discuss the tachatcal require- '
