ATTACHMENT I WASHINGTON PUBLIC POWER SUPPLY SYSTEM NUCLEAR PROJECT N0. 2 DOCKET N0. 50-397 LICENSE NO. CPPR-93 AMENDED RESPONSE TO INSPECTION REPORT 82-21 NOTICE OF DEVIATION ITEM D For purposes of clarity, the deviation is repeated followed by our response.

FSAR Amendment 23, Table 8.3-25 " Division markers for equipment, racc-ways, and cables external to PGCC" states that Non-Class 1E B0P Division B shall be. identified with gold marker background colors and black character colors.

Contrary to the above, it was determined on September 1,1982 that in the cable spreading room, tray section 7252, labeled S-Div-B in accordance with Table 8.3-25 above, there were numerous cables identified with blue markers at approximately 5 foot intervals similar to PGCC Class 1E Division 2. FSAR Table 8.3-25 does not provide for such markers external to the PGCC. There appeared to be no divisional markers for thesa cables in accordance with FSAR requirements throughout the approximately 75 to 100 feet of routing within the cable spreading room.

This is a deviation.

Supply System Response As a part of the PGCC design, there has been a need to interconnect the Main Control Room Balance of Plant (B0P) front benchboards with the vertical boards located at the back of the room. However, the PGCC ducts provided do not allow such routing to be practicable. As an alternate, a network of raceways has been used in the cable spreading room to route these interconnecting cables. The listing of these interconnecting cables which are routed in these raceways is documented on Burns and Roe drawing E766, sheets 8, 9 and 10. These cables are treated as an exception to the standard PGCC routing. As a minimum, they shall be identified with general plant markers while in the cable spreading room and with PGCC markers while in the PGCC. A cross-reference between the respective identification schemes will be available in the Burns and Roe design documents.

A statement of this exception will be included in a FSAR revision stipulating the cable identification requirements for these specific cables. In addition, Revision 2 of the Electrical Separation Practices document will address this exception.

Attachment I Page 2 Corrective Steps Taken The FSAR and Electrical Separation Practices document will address this exception. An inspection and rework as necessary will be performed on the subject cables to ensure they comply with the above requirements.

Results Achieved-Clarification of electrical separation criteria with respect to the subject exception and compliance with current criteria.

Corrective Action Complete The subject FSAR revision and Revision 2 of the Electrical Separation Practices document will be issued by April 15, 1983.
