RE: WM. H. ZIMMER NUCLEAR POWER STATION - UNIT 1 10CFR50. 55 (e) , ITEM E-30, LACK OF INSTALLATION INSPECTION OF NON-CLASS IE CABLES IN PANELS W.O. 57300, JOB E-5590, FILE NO. 956C, E-30 This letter constitutes an interim report concerning the subject condition reported to the Commission on October 27, 1982.

Our last report, LOZ-83-0155, was submitted on September 30, 1983. CG&E has determined this condition to be a reportable deficiency under 10CFR50.55 (e) .

The subject condition occurred when construction and inspection procedures were not revised to provide instructions for the installation and inspection of non-essential (white) and associated cables in accordance with revised separation criteria issued by the architect engineer. This lack of inspection resulted in a lack of documentation verifying compliance with the separation criteria.

Two types of cable configurations could occur in such a manner that a redundant safety function might be degraded due to a single failure or event.

The first concern is interaction between an essential cable of one division and a redundant associated cable of another division.

The second concern is that a non-essential (white) cable could provide a common denominator for a single failure between two redundant essential cables.

Therefore, the lack of installation verification by inspection of Non-Class lE (Associated and White) cables when 9 8401100294 831230 P

e Mr. J.G. Keppler Regional Administrator December 30, 1983 LOZ-83-0250 Page 2 bundled with class lE cables is a significant deficiency . The

~

failure to properly incorporate instructions and criteria in construction and inspection procedures also represents a breakdown in_the Constructor's Quality Assurance Program. As a result, this deficiency is reportable under.the requirements of 10CFR50.55(e).

As we indicated in LOZ-83-0155, an evaluation of the cable installation for all essential panels would be performed to identify and resolve any violations._ NEP 8.5, " Engineering Review of Cable Separation for Essential Panels," was implemented in June, 1983 to address this concern. The program established a method of field review to verify that Class lE and associated cables have been properly separated from redundant Class 1E, associated and non-essential (white) cables. The field review encompassed the inspection of cables for separation inside essential panels and outside essential panels to their first raceway. The Quality Assurance Department provided 100% 0.C.

surveillance of the field activities to ensure program compliance. Potential deviations were dispositioned and analyzed under EPP-5, " Cable Analysis for Cables in Air and Panel" by Sargent & Lundy (S&L) with a review by CG&E. A total of 184 panels were encompassed by the program. Out of the 2293 potential deviations identified, 575 will require some rework.

Copies of all interaction sheets will be attached to Nonconformance Reports (NR's) on a per panel basis and processed accordingly.

L Rework associated with these NR's will be accomplished in accordance with the Course of Action submitted to the Commission on October 5, 1983. Construction and inspection procedures will be written and training programs established for any new work. A final report will be submitted upon completion of the corrective action.
