MINIMUM SEPARATION DISTANCE CAN BE i

ESTABLISHED BY ANALYSIS OF THE PROPOSED CABLE INSTALLATION. THIS ANALYSIS SHALL BE BASED ON TESTS PERFORMED TO DETERMINE THE I

TEST PROGRAM THIS TEST PROGRAM IS TO DEMONSTRATE THAT CERTAIN I

DETAILED ARRANGEMENTS OF CABLES AND RACEWAYS i

AS PRESENTLY INSTALLED AT BVPS-2 HAVE INHERENT CONSERVATIVE ATTRIBUTES AND THAT VARIOUS OPTIONAL MEANS EXIST OF ACHIEVING ACCEPTABLE SEPARATION WHICH WOULD MITIGATE THE EFFECT OF CONSEQUENTIAL WORK ON THE SCHEDULE.

DISCUSSION The, presentation was initiated with a summary of the results of the December 20, 1983 meeting and a discussion of the progress of the BVPS-2 Electrical Separation Program.

Specif'c accomplishments cited for the pro-gram included:

i.

Development and implementation of design criteria and installation documents reflecting the R.G. 1.75 criteria.

ii.

Development and implementation of a training program for engi-neers, designers, QC, and construction personnel.

iii. Development and implementation of a computer-based system to track existing separation problems.

iv.

Completion of an engineering walkdown of the plant to identify spatial separations less than the R.G.

1.75 criteria.

Important terminology used in the separation program was presented and defined.

(See Slides 2 through 5 in Attachment 2.)

It was reported that the engineering walkdown identified 1108 cases where rework was required. Of these, only 50 are remaining to be resolved by SWEC engineering and 348 by the electrical contractor's design group.

Engineer-ing will complete disposition of these items by September 30, 1984.

The design group's target for completion is also September 30, 1984.

Construction has committed to complete rework on all items by January 1, 1985.

The presentation also noted that new work is proceeding in a fashion that will allow the installation of covers and wraps as shown in the engineering docusents (specifications, drawings, etc.).

A schedule was presented (Attachment 2, Slide 34) that indicated that consequential work will start approximately April 1985.

Details of the proposed consequential work designs to satisfy Regulatory Guide 1.75 (Rev. 2) s.eparation criteria (e.g., tray covers and cable wraps) were presented.

Slides 19 through 25 provide some of these details.

A sam-ple of the Sil-temp material which will be employed for cable wrapping (where required) was offered for inspection.

It was indicated that the detail designs would be documented in an amendment to Section 8.3 of the BVPS-2 FSAR.

A test program, which should justify reductions in the scope of the conse-quential work requirements, was described.

NRC representatives noted that this represented a change in program emphasis as previously discussed in December 1983 and expressed interest in reviewing the proposed test program.

The test program will be discussed with the NRC during the next licensing meeting, expected during the last week of September 1984.

It was stressed to the NRC that BVPS-2 would successfully meet R.G.

1.75 criteria with the B4-1224106-51

+

3 present. separation program, even if the test program results do not estab-lish the bases for reductions in consequential work scope.

An updated schedule for the program (Slides 33 and 34) was also presented.

The presentation was concluded with a review of the issues raised by Region I personnel in Unresolved Inspection Item 82-05-01.

DLC indicated that it felt that all of the issues had been addressed in the presentation and therefore hoped that this item could be closed.

At. the conclusion of the presentation, a plant tour was conducted which included the rod control area, the cable spread area, and the main control room.

The purpose was to show installations with insufficient separation which required rework to meet the separation criteria.

An installation using the protective Sil-temp wrap was also viewed.

DLC stated it would issue minutes of the meeting to the NRC by September 15, 1984.

In addition, a meeting with Mr. John Knox (NRR) was tentatively scheduled for September 26 to review the proposed plan for meeting the sepa-ration requirements, address the test plan, and provide details of accept-able consequential work designs.
