NOTICE OF VIOLATION Commonwealth Edison Company Docket No. 50-455 As a result of the inspection conducted on July 16 - September 12, 1986, and in accordance with the " General Policy and Procedures for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1986), the following violation was identified:
10 CFR 50, Appendix B, Section XI, requires that all testing necessary to demonstrate that components will perform satisfactorily be accomplished in accordance with written test procedures.
Byron FSAR Section 6.2.2.4.1.d requires that the Reactor Containment Fan Cooler (RCFC) system be demonstrated capable of operating at air densities
~
approximately equivalent to that following a loss-of-coolant accident.
Containment Ventilation test 2.93.62 implemented these requirements.
Contrary to the above, on July 9, 1986, test 2.93.62 was approved without specifying the containment air density necessary to demonstrate that the RCFCs would perform satisfactorily for conditions approximately equivalent to that following a loss-of-coolant accident. (Note:
By observation and discussion with the licensee, it was determined that the necessary data had been taken and that the necessary calculations had been performed for both Units 1 and 2).
This is a Severity Level V violation (Supplement II) (455/86024-01(DRP)).
Pursuant to the provisions of 10 CFR 2.201, you are required to submit to this office within thirty days of the date of this Notice a written statement or explanation in reply, including for each violation:
(1) corrective action taken and the results achieved; (2) corrective action to be taken to avoid further violations; and (3) the date when full compliance will be achieved.
Consideration may be given to extending your response time for good cause shown.
