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 on inspection conducted on March 10-14, 1986, and in accordance with the NRC Enforcement Policy (10 CFR 2, Appendix C), the following viola-tions were identified:

A. Technical Specification 4.4.II.A states, " leak detection tests of the following components shall be performed locally at a pressure of not less than 40 psig, using halogen gas detection, soap bubbles, pressure decay, or other methods of equivalent sensitivity... isolation valves on lines penetrating containment."

NRC Safety Evaluation report dated May 7,1982, supporting Amendment No.

49 to the Facility Operating License states, " Type C testing with water as a test medium... is acceptable only where the hydraulic test is used to demonstrate a water seal at the penetration throughout the post accident peri.od."

Contrary to the above, as of March 14, 1986, numerous isolation valves on lines penetrating containment were being tested using water as the test medium when the purpose of the test was not to demonstrate a water seal at the penetration. Further, this testing has not been shown to have sensitivity equivalent to the approved test methods.

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

B. Technical Specification 1.8 states, " Containment integrity shall exist when: ... All penetrations required to be closed during accident condi-tions are... closed by manual valves..."

Technical Specification 3.11.B states, " containment integrity shall be maintained whenever the reactor coolant system is above 300 psig and 200 F..."

Contrary to the above, on January 7, March 7 and November 15, 1985, valve SA-V-413, a designated locked closed manual containment isolation valve, was opened to perform a surveillance test when containment integrity was required.

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

C. 10 CFR 50.59(b) states, in part, "... records shall include a written safety evaluation which provides the bases for the determination that the change, test or equipment does not involve an unreviewed safety question."

Appendix A 2 Contrary to the above, valves FM-MOV-31 and SA-V-413 were designated as containment isolation valves for penetrations P-80 and P-62 without the required safety evaluation being performed to determine that no un-reviewed safety questions exist as a result of the change.

This is a Severity Level IV Violation. (Supplement 1)

Pursuant to the provisions of 10 CFR 2.201, Connecticut Yankee Atomic Power Company is hereby required to submit to this office within thirty days of the date of the letter which transmitted this Notice, a written statement or explanation in 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.

Where good cause is shown, consideration will be given to extending this response time.
