APPENDIX A NOTICE OF VIOLATION Connecticut Yankee Atomic Power Company Docket No. 50-213 Hartford, Connecticut 06101 License No. DPR-61 As a result of the insp.'ction conducted on March 29 through May 2, 1989, and in accordance with the NRC Enforcement Policy (10 CFR Part 2. Appendix C), the following violation was identified:

Connecticut Yankee Atomic Power Company, Haddam Neck Plant Technical Speci-fication 3.11, Containment, requires that containment integrity be main-tained whenever the RCS (Reactor Coolant System) is above 300 psig and 200 F.

Contrary to the above, on March 27, 1989, with the RCS greater than 300 psig and 200 F, PW-V-600 was open.

This is a Severity Level IV Violation (Supplement I).

Pursuant to 10 CFR 2.201, Connecticut Yankee Atomic Power Company is hereby required to submit to this office, within thirty days of the letter which transmitted this Notice, a written reply, including: (1) the corrective steps which have been taken and the results achieved; (2) corrective steps which will be taken to avoid further violations; and (3) the date when full compliance will be achieved.
