50-358, CONSTRUCTION PERMIT N0. CPPR-f3, W.0. #57300-957, JOB E-5590 Gentlemen:

This letter constitutes our formal reply to the subject inspection report. It is our opinion that nothing in the report or in this letter is of a proprietary nature.

Item I -

Inspection of Electrical Modifications by E0TD Personnel The Electric Operating Test Department (E0TD) of the Cincinnati Gas & Electric Company has been assigned to the Wm. H. Zimmer Project for the sole purpose of electrical construction testing. All manpower, supervision and procedures are provided by the Electric Operating Department which is independent of the Construction and Engineering Divisions.

The E0TD personnel use the approved test procedures to verify installation or modifications made by Foothill Electric Corporation (FEC) craft personnel.

A) Corrective Action Taken and Results Achieved Electric Operating Test Department personnel have been informed that all supervision of electricians installing, changing or otherwise modifying equipment or wiring must be provided by Foothill Electric engineering or supervisory personnel. It was also emphasized that E0TD personnel are to perform only testing responsibilities. These instructions were provided to E0TD personnel in January,1980.

Henry J. Kaiser QC electrical inspection personnel were re-instructed concerning the performance of those QC inspections applicable to FEB 25 gggo

.. Mr. Gaston Fiorelli U. S. Nuclear Regulatory Corrrnission Region III February 20, 1980 - QA-1260 Page 2 modifications, as required by construction inspection plans; i.e.,

crimping of lugs, removal of lugs and relugging as required, assur-ing that crimping tools are within calibration limits, etc.

Assurance that the terminai, ans are in accordance with the modifying design document is the responsibility of the E0TD personnel.

The above actions have directed that E0TD do not supervise install-ing personnel and also ensure that QC inspections are appropriately performed to assure that terminations comply with design criteria.

B) Corrective Action Taken to Avoid Further Noncompliance An audit will be performed to assure that the previously described instructions are being complied with by both E0TD and Henry J. Kaiser electrical QC inspection personnel. Random surveillance will also be provided by the Cincinnati Gas & Electric Company Quality Assurance personnel, Generation Construction personnel, and the Henry J. Kaiser electrical Quality Assurance engineer to assure that the requirements described in this letter are maintained in compliance.

C) Date When Full Compliance Will Be Achieved The audit will be performed on or before March 15, 1980 and quarterly surveillances conducted until completion of construction. ,

l Item II - Dust Accumulation on Electrical Penetration Terminal Blocks  !

A) Corrective Action Taken and Results Achieved Nonconformance-Report E-2423 was prepared identifying accumulation of dust on the penetration terminal blocks. The disposition of the Nonconformance requires complete cleaning of both sides of the penetration. It was further stipulated that QC personnel would witness the cleaning operation prior to closing the penetrations with gasketed covers.

B) Corrective Action Taken to Avoid Further Noncompliance Penetrations will be maintained in a closed condition employing sealing tape to preclude entry of dust until such time as entry is required for the continuation of construction. Tags will be placed on both sides of the penetration stating that the penetra-tion has been cleaned and that re-entry will require the witness of a QC inspector, who will assure that cleanliness is maintained prior to reclosing the penetration.
