50-412/84-09 and listed in Appendix B (Notice of Deviation) attached to your letter to Mr. E. J. Woolever, dated September 26, 1984.

The following examples have been identified as a deviation from your commitments:
- 1. Your commitment required revision to Stone and Webster Document 2BVM-88 to establish overfill criteria fo r cable raceways.
You committed to complete and issue this revision by June 29, 1984.
Contrary to the above, as of August 1,
1984, this document was not revised.
- 2. Your commitment required revision to Stone and Webster Specification 2BVS-931 to address requirements and controls on visible cable tray overfill. You committed to complete and issue this revision by June 8, 1984.
Contrary to the above, as of August 1,
1984, this document was not revised.

- 3. Your commitment required revision to Stone and Webster Field Construc-tion Procedure FCP-431 to provide information to construction for control of cable raceway fill.
You committed to complete and issue this revision July 30, 1984.
Contrary to' the above, as ~ of August 1,
1984, this document was not revised.
- 4. Your ' commitment required revision to Duquesne Light Inspection Proce-dure IP-8.4.1 to establish inspection criteria for cable tray overfill.
You committed to complete and issue this revision by July 30, 1984 Contrary to the above, as of August 1,
1984, this document was not revised.
Response
- 1. 2BVM-88 has been revised (Addendum 1, dated August 10, 1984) to deline-ate the engineering review procedure which must be completed prior to authorizing a cable tray overf111.
These procedures include a check-list which will accompany all new computer overfill authorization forms and a list of required approval signatures.
In the case of C and X trays, 100 percent fill in the design-basis computer system is based on a 3 inch usable depth of cable tray.
However, all trays at BVSP-2 are constructed with a 4 inch usable depth.
Therefore, if projected fill is between 10 0 and 133 percent, no detailed review effort will be performed.
If the projected fill is greater than 133 percent, it will be verified that no practicable alternate routing exists.
The engi-neers will then establish that the cable depth due to the new cables will be less than 1-1/2 inches above the tray side rails and will determine the projected weight due to the new cables. The signature of the Lead Structural Engineer (or his designee) will be required if the projected weight of tray cables, after overfill, exceeds 35 lb/ft.
If the projected depth is greater than 1-1/2 inches above the side rail, the overfill authorization will not be approved.
Final cable installation and tray fill verification will be accom-plished by DLC Site Quality Control (SQC).
- 2. Engineering and Design Coordination Report (E&DCR) 2P-4505 was issued August 2, 1984, to revise 2BVS-931 in accordance-with the response to item 1 above.
The tray fill controls discussed in E&DCR 2P-4505 apply to both safety and nonsafety-related trays as well as tray fittings (e.g., tee's, crosses, etc.).
3&4. Change No.15 to FCP 431, " Cable Pulling" was issued August 3,1984, to meet commitment No. 3 above. Site Quality Control (SQC) has revised IP 8.4.1, dated August 9, 1984, to reflect the above requirements.

United. States Nuclect -R2gulatory Connaission L hr.; Richcrd W.' Stcrostecki Page 3 The revisions to FSAR Table 8.3-4 were submitted to the NRC in 2NRC-4-084 dated June 15, 1984. The change to the FSAR has been incorporated in
' Amendment 8.
The above actio'ns. complete the commitments documented in.2ASR-Oll26 and 2ASR-Oll35 from the meetings of May 17, 1984, and.May 24, 1984.
Comple-tion of these commitments should provide the necessary controls on :the amounts of cable overfill allowed.
Completion of the revisions to the FSAR Table 8.3-4 ensures an accurat e description of the amount of tray fills.
These actions should provide the necessary information in order to close Unresolved Item 83-05-09, " Cable Raceway Fill."
