Subject:

Braidwood Station Units 1 and 2 Additional Information on Environmental Qualification of Okonite Tape Splices at Braidwood Station NRC Docket Nos. 50-456 and 50-457

Reference:

Teleconference between Commonwealth Edison Company (CECO) and the Nuclear Regulatory Commission (NRC) dated March 3, 1994, Regarding Additional Information Concerning Okonite Tape Splices As discussed during the reference teleconference between the Nuclear Regulatory Commission (NRC) and the Commonwealth Edison Company (CECO), CECO agreed to submit the attached information in response to the questions on splicing technique continuity at Braidwood Station.

Attachment 1, a letter from Okonite Company dated March 31, 1978, provides the basic splicing detail utilized at Braidwood Station. This detail is shown on Okonite drawing D-11547 which provides instructions for splicing 12/c#14 600V Okonite cable.

Commonwealth Edison's position in 1978 was to restrict the number of splices allowed during construction. This position is delineated in Sargent and Lundy letter dated December 11, 1978 (Attachment 2). In instances where control or instrumentation cables were " pulled short,"

the cables were terminated on terminal blocks and a new cable was installed from this terminal point to the end equipment. This position was reaffirmed, in a letter to the Braidwood site via Sargent and Lundy letter dated October 10, 1983 (see Attachment 3).

In August of 1983, note #76 was added to Sargent & Lundy drawing 6/20E-0-3390A Rev. AD (Attachment 4) and gave direction to tape butt splices similarily to Okonite instructions for taping pigtails splices on motor connections. Note #76 on drawing 6/20E-0-3390A Rev. AE (Attachment 5) was revised to give more specific details on splicing and included a referece to Okonite drawing D-11547 received in the March 1978 transmittal. This note has since appeared on drawings with only minor changes in content and a shift to a drawing series which was created to bring all notes which apply to a similar piece of equipment or installation activity (i.e., cable, conduit, etc.) to a common location. It now appears as note #10A on drawing 20E-0-3000N SH-2 Rev. H (Attachment 6) where it has resided since this drawing series was begun in 1985.

e i Mr. William Russell April 15, 1994 Additionally, attached is a copy of Byron /Braidwood FSAR Question 040.3 dated May 1979 (Attachment 7). These questions were asked and responded to during the original NRC review of the pre-licensing Byron /Braidwood FSAR. The response provides the manufacturer's names and types of cable to be used for power, control and instrumentation circuits at Byron and Braidwood. As indicated, Okonite is the specific vendor for power and control cable. This information was incorporated into the first revision of the FSAR but was originally provided to the NRC for review under that question number.

If you have any questions concerning this response please contact me at-(708) 663-6484.

i INSTRUCTIONS FOR A STRAICHT SPLICE FDR MULTI-CONDUCTOR, RUBBER INSULATED, OKOLON JACKETED NUCLEAR STATION C0tEROL CABLE Drawing No. D-11547 ite v , A

1. Study the drawing and instructions for design and dimensions of the splice and the step by step procedure.

2. Determine the number of steps in the splice and the approximate number of conductors I to be jointed at each step and the overall length (L) of the completc.d splice from  !

the following table: I l NUMBER OF CONDUCIORS NINBER OF NUMBER OF JOINIS OVERALL LENCIH IN CABLE STEPS PER STEP (L) 2- 3 1 3 10 4- 7 2 4 12 8 - 14 2 7 12 15 - 21 3 7 14 22 - 28 4 7 16 29 - 37 5 8 18 l

3. Form and rack the cables into their final position and cut the ends so that the cables overlap for the distance of (L) minu s (4) inches .

4 Remove the cable jacket from both cables for a distance of (L) minus (4) inches.

5. Remove the insulation belt and fillers to within (1) inch of the cable jacket on both cables.

6 Match one of the center conductors from both cables. Cut off the excess length from one or both conductors as necessary to locate the joint at the proper step in the splice, cutting the conductors so that they butt together. Remove the insulation for a distance of (1/2) the connector length from each conductor. Place the conductors in the connector being sure that they butt together in the center of the connector and compress the connector onto the conductors using the correct tool in accordance with the connector manufacturer's instructions.

7 Buff the surface of the insulation on each side of the connector for a distance of (1/2) inch. Wipe the buffed insulation surface with a cloth moistened with chlorothene or other suitable non-toxic, fast drying solvent and allow to dry. Apply a thin layer of Okonice cement to the buf fed surfaces and allow to dry until tacky.

8. . When dry, apply one half-lapped layer of Okonite T-95 insulating tape over the connector lapping onto the insulation on either side of the connector for (1/2) inch.

9 Apply one half-lapped layer of Okonite No. 35 jacketing tape over the applied Okonite T-95 insulating tape.

. Repeat the above procedure on all the remaining conductors working from the center conductor outward and staggering the joints so as to keep the overall diameter of the splice as small as possiole.

Drawing No. D-11547 key. t. Page %

11. Buff the surface of the insulation belt with Aloxite cloth. Wipe the buffed surface with a cloth moistened with chlorothene or other suitable non-toxic, fast drying solvent and allow to dry.

12. Uhen dry, apply a thin film of Okonite cement to the buffed insulation belt surface and allow to dry until tacky. ,

i

13. Apply one half-lapped Icyer of Okonite No. 35 jacketing tape, with minimum tension l necessary so that it conforms to the contour of the splice. Apply the tape over the bundled conductor splices up to the edge of the cable jacket ca each cable.

14 Buff the surface of the cable jacket for approximately (2) inches on each cable. Wipe the buffed cable jacket surfaces with a cloth moistened with chlorothene or other suitable non-toxic, fast drying solvent and allow to dry.

15. When dry, apply a thin film of Okonite cement to the buffed cable jacket surfaces and allow to dry until tacky.

16. Apply a minimum of (2) half-lapped layers of Okonite No. 35 jacketing tape, with minimum tension necessary so that it conforms to the contour of the splice. Apply the tape over the complete splice area and lap onto the cable jacket for approximately j (2) inches.

• • ' have respond,ed that cable splices should be installed only where ,

specifically called for on the S&L drawings and that any additional I ow cable splices proposed by Construction personnel will be reviewed  !

Mr. Dennehy that Regulatory Position C.5 of NRC Regulatory Guide

3. Terminations at terminal blocks are more rollable and require loss installation time than a splico.

4. Both the installation of terminal blocks or a splico requires a the addition of a junction box.

5. For future modifications, the installation of a new cablo (

terminated at the terminal block will require ices time and be more reliable than the inutallation of a new cabic and splico.

In view of the above, we believe it to be in Commonwealth Edison  :

Ccrapany's best int est to add terminal blocks where cabic extension f is required for control and instrumentation cables. ,;

I However, due to recent tost results on Marathon terminal blocks in boxes exposed to a LOCA environment, it is a requirement that, in such environments, safety-related low level instrumentation circuits -

shall not be terminated at terminal blocks provided and inntalled by the electrical contractor Theref ore, where cabic extension is required f or control circuits, terminal bicckr shoul.-I be unod. Whero extension of cables with low 0 -

level instrumentation circuits is required: 1) for safety-relatco circuits exposed to a LOCA or a Main Steam Line Dreak environment, r a splice must be used: 2) in all other cases, terminal blochn should- ',

be used. _

If you have any questions, please call me. -
