Dear Mr. I,
leberman Per the discussion and agreement between you and J. V. Sipek of my staff, k
lilinois Power (IP) requests a thirty day extension to the date for replying to the Notice D.
of Violation and Civil Penalty concerning circuit breakers contained in Enforcement -
Action 97 132. This extension is requested so that lessons learned and corrective actions from the August 5,1997, Westinghouse safety related circuit breaker failure can /1 be analyzed and included in the response. IP adtr.its the violations outlined in p
Enforcement Action 97-132 occurred and has enclosed the $110,000 for payment of the civil penalty.
Notwithstanding this extension request, msny actions have been completed in response to the problems described in the Notice of Violation. A detailed plan was developed to provide assurance that the safety related low and medium voltage circuit breakers would operate when required. This plan was previously provided to the Nuclear Regulatory Commission (NRC), Region Ill, Regional Administrator in letter U-602721 dated April 14,1997. The results of the actions taken to provide reasonable assurance that the safety-related low and medium voltage air circuit breakers would operate when required were provided in letter U 602782 to the Nuclear Regulatory Commission (NRC), Region III, Regional Administrator. Additionally, subsequent to the failure of the Westinghouse 4160-volt safety related circuit breaker on August 5, nW O llIRlHJIJR,HLI 9709100043 970829 PDR ADOCK 05000461-G.
- PDR,
U 602824 Page 2 1997, a team was fonned to identify the cause of that circuit breaker failure. This team included individuals from the circuit breaker manufacturer, outside circuit breaker experts and equipment failure determination experts. IP has determined the cause of the August 5,1997, circuit breaker failure and is conducting extensive maintenance to correct this condition and also performing additional preventive maintenance activities in other Westinghouse 4160 volt circuit breakers. These corrective actions will be outlined in the final response to this siolation.
Also, the cause of the failure to use approved lubricants and cleaners on circuit breakers at Clinton Power Station has been determined. Actions I ave been taken to ensure the proper use of these lubricants and cleaners. These actions include: revising circuit breaker maintenance procedures to identify specific lubricants needed during maintenance by noun names, conducted seminars with maintenance technicians on ensuring consumable materials, such as cleaners and lubricants, are approved for the intended application prior to use, and preparing a revision to maintenance procedures to clarify the requirement to ensure that only approved consumable materials are used. IP !s continuing to look at actions necessary to improve the preventive maintenance program.
IP has also taken steps to improve the conective action program. A Diiector from outside IP has been hired to improve the conective action program. Administration of the corrective action program has been moved from the Plant Stafrto a new organization.
This change should provide a greater emphasis on the corrective action program. Also, IP has instituted an Independent Analysis Group to conduct detailed root cause investigations of significant station events, l{owever, recent circuit breaker failures have identified shortcomings in the conective action program that need to be addressed.
In order to provide a comprehensive response ta the identified shortcomings in the conective action program and describe other conective actions that have been recently undertaken an extension to respond to this Notice of Violation is necessary. IP views this Notice of Violation as significant and believes that an extension is warranted so that the actions to improve the corrective action program is contained in the response.
Please contact me at (217) 935 8881 extension 3400 ifyou have any questions regarding this request to extend the due date for the response to the Mutio of ViolatU.
contained in Enforcement Action 97132.
