+ . . . . .o# JUL. 0 3 1985 Docket Nos.: 50-445 and 50-446 FACILITY: Comanche Peak Steam Electric Station, Units 1 and 2 APPLICANT: Texas Utilities Electric Company

SUBJECT:

MEETING HELD ON JUNE 13 AND 14, 1985 IN ARLINGTON, TEXAS TO DISCUSS THE DEVELOPMENT OF THE APPLICANT'S PROGRAM PLAN On June 13 and 14, 1985, a meeting was held with Texas Utilities Electric Company and the NRC staff to discuss the development of the Applicant's Program Plan. The meeting was held at the Arlington-Sheraton hotel and was transcribed. Participants are identified in the transcript. A copy of Applicant's viewgraphs are enclosed, as is a copy of the transcript.

The meeting was requested by the NRC staff to get a status on the develop-ment of the Applicant's Program Plan which is to address all issues needed in order for NRC to reach a licensing decision on Comanche Peak. The Pro-gram Plan will address all concerns expressed to date from all sources and do sampling in other areas as well in order to provide reasonable assurance that the plant has been both designed and constructed in accordance with regulatory requirements.

As part of the program, Texas Utilities identified some of the following activities:

1. Changes are being made in Texas Utilities management within the nuclear organization.

2. Stone and Webster will be reevaluating all ASME Class 2 and 3 pipe supports larger than 2" (and all Class 1 supports not designed by West-inghouse). This involves about 9000 supports, with a scheduled completion date of December 20, 1985.

3. Ebasco will be reevaluating electrical cable tray and conduit supports.

4. The Comanche Peak Response Team (CPRT) will be responding to the NRC Technical Review Team findings identified in SSER's 7 through 11 in the areas of QA/QC, protective coatings, test programs, electrical /instru-mentation, mechanical / piping, civil / structural and miscellaneous.

The formal program plan will 'be submitted to NRC for approval in early July 1985.

-lNDEPENDENT ASSESSMENT PROGRAM

-NRC ASLB PROCEEDINGS

-NRC LICENSING REVIEW - TRT, SIT, SSERs .

-NRC INSPECTION PROGRAM - R IV, CAT

-TUGCO HAS CHARGED THE CPRT WITH RESPONSIBILITY FOR DEVELOPMENT AND IMPLEMENTATION OF A PROGRAM THAT WILL
