\E d l OCT 191983 Docket No. 50-295 License No. DPR-39 EA 88-199 Commonwealth Edison Company ATTN: Mr. James J. O'Connor President l Post Office Box 767 Chicago, IL 60690 l Gentlemen:

SUEMECT: NOTICE OF VIOLATION This refers to Licensee Event Report No. 86-040-00 and Supplemental Licensee Event Report No. 86-040-01 that Comnonwealth Edison Company (CECO) submitted I to NRC by letters dated Nove:ber 25, 1986 and May 1, 1987, respectively.

l These letters reported that, while inspecting environmentally qualified (EQ) l spitees in Zion Unit 1, your staff identified three transmitters that had I improperly terminated leads. This matter, which constituted a violation of NRC regulatory requirements, was discussed on August 17, 1988 during an enforcement conference in the NRC Region III offices between Mr. T. J. Maiman and others of your staf f and Mr. A. B. Davis and others of the NRC staff.

1 The violation described in the enclosed Notice of Violation involved the installation of two Rosemount transmitters and one Barton transmitter with leads landed on unqualified terminal blocks rather than spliced uttitzing environmentally qualified splices, as required. Ceco clearly should have known that the terminal blocks were not qualified because its EQ files did not contain any information to show that the terminal blocks had been i qualified by test and/or analysis for use in this EQ application. Also, CLCo itself recognized that terminal blocks could not be used for instrumentation l

inside containment such as the pressure transmitter at issue. In addition, a modification package involved in this violation (22-1-81-49) specified splices in the installation of the transmitters. However, specific installation instructions were issued without clear direction to splice the leads and this resulted in two transmitters (ILT-503/1LT-504) being improperly l installed with terminal blocks while two transmitters (1LT-501/1LT-502) were installed with the required splices.

In accordance with the Modified Enforcement Policy Relating to 10 CFR 50.49, contained in Generic Letter 88-07 (Enclosure 2), the violation described in the enclosed Notice has been determined to be an isolated problem, having affected a limited number of systems or components, and has been classified as an EQ Category C violation. Normally, a civil penalty would be proposed; however, af ter consultation with the Director, Office of En'orcement, and the l

1 Commonwealth Edison Company 2 Deputy Executive Director for Regional Operations, I have decided that a civil penalty will not be proposed in this case because CECO has satisfied the five criteria of the Modified Enforcement Policy Relating to 10 CFR 50.49 centsined in Generte Letter 88-07, which provide a basis for full mitigation. These criteria are: (1) the violation was isolated and affected a limited number of systems (Category C violation); (2) CECO identified the violation; (3) the violation was promptly reported to the NRC; (4) the violation was corrected and full compliance was achieved within a reasonable time; and (5) Ceco demonstrated best efforts to complete EQ within the deadline.

The NRC has reviewed your LER 86-040-00 and supplementary LER 86-040-01 i transmitted by letters dated November 25, 1986 and May 1, 1987, respectively. -

There LERs provided a description, a cause, and an analysis of the event, as well as your corrective actions. These corrective actions have been reviewed and the NRC has no further questions regarding this matter at this time.

Confaquently, a reply to the Notice is not required.

In accordance with Section 2.790 of the NRC's "Rules of Practice," Part 2 Title 10 Code of Federal Regulations, a copy of this letter and its enclosure well be placed in the NRC Public Document Room. ,

Sincerely, ,  :
