Appendix A NOTICE OF VIOLATION Commonwealth Edison Company Docket No. 50-249 As a result of t.he inspection conducted on January 1-30, 1981, and in accordance with the Interim Enforcement Policy, 45 FR 66754 (October 7, 1980), the following violation was identified:
10 CFR 50 Appendix B, Criterion XIV requires that measures be established i
for indicating the operating status of structures, systems, and components of the nuclear power plant..., sach as tagging valves and switches to pre-vent inadvertant operation. Dresden Administrative Procedure (DAP 3-5) states it's purpose in part, "This procedure will provide a record of the equipment status before, during, and af ter an outage so that abnormal system configurations can be evaluated." CECO Quality Assurance Manual l
procedure 3-52 states the Shift Engineer will take appropriate action and i
remove equipment from service and when satisfactory, clear the outage and declare the system or component operable.
Contrary to the above, on January 27 aud 28, 1981, while several outages were in progress on the 3A Reactor Feedwater Pump (RFP), a drain valve in the RFP's minimum flow piping was opened and the change in valve status was not included in the outage documentation, nor was the Shift Engineer informed of the change in status. When the outages were cleared on January 28, 1981 the valve was inadvertantly left open, resulting in increased condenser air inleakage, increased air ejector flow, an increase in off gas activity, and the potential for a unit trip.
This is a Severity Level V violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, you are required to submit to this office within twenty-five days of the date of this Notice a written statement or explanation in reply, including for each item of noncompliance:
(1) corrective action taken and th results achieved; (2) corrective action to be taken to avoid further nonconfliance; and (3) the date when full com-pliance will be achieved. Under the authority of Section 182 of the Atomic Energy Act of 1954, as amended, this response shall be submitted under oath o 7.
affirmation.
