Y NRC Docket Nos 50-10 50-237 50-249 ATTACHMENT A COMMONWEALTH EDISON ATTACHMENT RESPONSE TO NOTICE OF VIOLATION The item of noncompliance identified in Appendix A of the NRC letter dated March 24, 1981 is responded to in the following paragraphs.
1.
As a result of the 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 for indicating the operating status of structures, systems, and components of the nuclear power plant..., such as tagging valves and switches to prevent 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 after an outage so that abnormal system configurations can be evaluated." CECO Quality Assurance Manual procedure 3-52 states the Shift Engineer will take appropriate action and remove equipment from service and when satisfactory, clear the outage and declare the system or component operable.
Contrary to the above, on January 27 and 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 docu-mentation, nor was the Shift Engineer informed of the change in When the outages were cleared on January 28, 1981, the status.
valve was inadvertantly lef t open, resulting in increased con-denser air inleakage, increased air ejector flow, an increase in off gas activity, and the potential for a unit trip.
Corrective Action Taken and Results Achieved The shift foreman who was involved in making the change to the drain valve has been individually retrained to ensure awareness of the importance of adding new items to the original outage documentation.
In addition, information will be added to the training material for all shift personnel reinforcing the need to record all items which are taken out of service subsequent to the original outage. This information will be conveyed to all shift personnel as part of their next "every sixth week" training session.
.p[$h8hAV2"~
Corrective Action Taken To Avoid Further Non-Compliance
' Because of the singular nature of the event and that the person in-volved as well'as all shift personnel are aware of the requirements for adding equipment to an outage, no further action is deemed necessary.
Date When Full Implementation Will Be Achieved The shift personnel training sessions will be completed by May 15, 1981.
