SUMMARY

OF JUNE 13, 1986, MEETING WITH PUBLIC SERVICE COMPANY OF COLORADO (PSC) TO DISCUSS STATUS OF FORT ST. VRAIN (FSV) EQUIPMENT QUALIFICATION (EQ) PROGRAM f

The meeting was held at the Counission's offices, Room P-118, Bethesda, i

g Maryland, on June 13, 1986, at 9:00 a.m. The purpose of this meeting was to i discuss the status of the FSV EQ Program. Of particular interest was PSC's progress in developing a basis for qualification of cables used in FSV's safe shutdown systems. Meeting attendees are listed in Enclosure 1.

i Overall Status PSC reported progress was being made in several EQ areas. Plant modifications were proceeding with Loop 2 in shutdown. EQ binders were receiving final review,and the EQ submittal would be delivered shortly.

PSC stated that all questions concerning the Steam Line Rupture Detection /IsolationSystem(SLRDIS)hadbeenanswered,andacopyoftheir i letter dated June 10,1985(P-86417)wassupplied. The staff stated that l the review of material on SLRDIS would now proceed, since the SLRDIS '

submittals had been finalized (see Enclosure 2). i

Cable Qualification i PSC sumarized the cable qualification methodology being applied to FSV in Enclosure 3. The general conclusion, using their methodology, was that all cross-linked polyethylene cable materials behaved in substantially the same manner. They stated that work done by the Tennessee Valley Authority substantiated this claim. The qualification methodology utilized thermal-lag analysis. However, the methodology being used was based on a prior-approved topical report contained in CE-NPD-255. PSC estimated that three cable binders would be ready for staff review and

l coment by mid-July. Tentatively, these binders are identified as  :

FSV51, FSV57, and FSV66. A complete listing of cable qualification binders is given in Enclosure 4.

The staff expressed concern that cable types other than those covered by I the qualification binders could be present in the plant. PSC restated that their audits had not revealed any other cables and they believed staff audits and inspections would confirm their conclusions, PSC noted that in the June 1,1986 summary of the May 2,1986 meeting, a statement was made that cables had to be identified by manufacturer and materials and that cable sampling had to be instituted in order to comply with 10 CFR 50.49. The staff stated that alternative approaches could be con-sidered. PSC also stated that it did not believe a cable sampling program was necessary, as stated in the April 10, 1986 sumary of the March 26, 1986 meeting. PSC stated they would demonstrate all cables were capable of withstanding the worst-case environment in the plant, so no testing would be needed. The staff agreed to clarify PSC's position in this meeting summary.
