Original Interrogatory 1:
Please identify the programs cnd procedures used j
i to verify that the octual environment in the os-installed position, for both operating and occident conditions over the plant design lifetime, for each safety-related' structure, system and component is bcunded by the conditions in its environmental and seismic tests for life and aging.
Supplemental Request:
In view of the recently discovered failures during NRC sponsored tests of the bonded jocket material of Okonite cables cs well cs other manufacturers, and in view of the wide ranging and not specific response provided by PG&E to Interrogatory 1,
please respond to the more specific questions:
1A Which maintenance and surveillance programs and which maintenance and surveillance precedures were used to determine if Okonite cables Cof the some general type involved in NRC IN 92-183, were installed at DCNPP in i
j cn environment that would result in a shorter operational lifetime than the qualified lifetime?
1B Were these predictive or recctive maintenance activities?
1C Did PG&E discover any potentially deficient qualified life of cable insulation or any as-installed environment inconsistent with the l
qualified environment?
If so, please provide the details of each instance.
1D Plecse provide copies of all documents in your possession, including but not limited to correspondence occurring between June 1992 and the present, between PGSE and C1] the NRC, [2] NUMARC, C3] EPRI, and C9]

Identify the maintenance and surveillonce procedures applicable to these cables and provide o summary-of their maintenance histories.
Original Interrogatory 24:
have you identified importent-to-screty components for which the octual operating environmental conditions are not bounded by the environmental porometers used to precondition the equipment to its end-of-installed life conditions?
If so, for each such cose, identify the component and describe the cctionts] that have been token or cre planned to be token.
Supplemental Request:
In view of the blanket answer to this question in the negctive, and in view of the problems recently identified with the bonded jockets of Okonite cables, please update your answer for i
Interragotcry 29.
In addition, please answer the following:
29A Hos PG&E identified any structures, systems or components for i
which the cetual operating environmental conditions are not bounded by the environmentcl porometers used to precondition the equipment to its end-of-instclied life conditions?
24B If so, for ecch such ccse, identify the component and describe the cction(s) that have been taken or are planned to be token.
