Senior Vice President, Nuclear Power 6N 38A Lookout Place l
1011 Market Street t
Chattanooga, Tennessee 37402-2801 Gentlemen:
SUBJECT:
ORDER IMPOSING A CIVIL MONETARY PEN.'.LTY - $75,000 (SEQUOYAHNUCLEARPLANT)
This refers to your letter of May 9,1990 in response to the Notice of ViolationandProposedImpositionofCivilPenalty(Notice)senttoyouon April 12,1990. Our letter and Notice described violations at the Sequoyah Nuclear Plant, Units 1 and 2, involving corrective actions to prevent RHR
) ump deadheading. A civil penalty in the amount of $75,000 was proposed to emplasize the need to ensure that potential conditions adverse to quality are adequately evaluated and prompt, effective corrective action taken.
In your response, you admitted the violations but requested reconsideration for escalation of the base civil penalty based on NRC identification and for lack of mitigation of the penalty >ased on corrective action.
After careful consideration of your response, we have concluded, for the reasons given in the Appendix attached to the enclosed Order Imposing Civil Monetary Penalty, that a sufficient basis was not provided for reduction of the civil penalty amount. Accordingly, we hereby serve the enclosed Order on Tennessee falley Authority imposing the civil penalty in the amount of Seventy Five ThousandDollars($75,000).
During our review of your response, we determined that certain information was unclear in your response and other information conflicted with information previously submitted.
Please provide to the Regional Administrator, Region II, the following information within 30 days of the date of this letter:
1.
Your response of May 9,1990 did not clearly address the reason and corrective action for Violation A, Example 1.
Son.e information on this violation was provideo in your enforcanent conference folicwup letter dated March 5, 1990.
Please oddress why no action was taken to preclude damage to an RHR pump due to deadheading when inforn.ation incicated that the Sequoyah design was susceptible to deadheading. Specifically, your response did not address why 20 minutes was used during your Emergency Procedure review as an acceptable time for RHR pump deadheading when TVA gg72 g y M 7
3 O
Tennessee Valley Authority calculations indicated that damage would occur after approximately 11 minutes. That information is considered important because had 11 minutes j
been used, it appears that these violations may not have occurred.
In addition, please provide your corrective actions to assure that when potential degradation of plant systems is indicated, appropriate measures will be taken to prevent the consequences.
2.
Please clarify your position on the utilization of the differential pressure data in your review of the deadheading issue between November 28 and December 5, 1989.
In your letter of March 5,1990, you indicated that TVA was not satisfied with the performance of the Systems Engineering i
group in the evaluation of the data. This concern is not reflected in your response to the violation.
3.
TVA addressed whether the response to Bulletin 88-04 contained comalete and accurate information in relation to the RHR pumps. However, t1e revised Bulletin response dated March 15, 1990 also indicated that the portion pertaining to the auxiliary feedwater pumps had been revised.
Please address the errors or omission of information in the entire Bulletin 88-04 response, and corrective actions to preclude submittal of incomplete or inaccurate data in the future.
4.
Please clarify the statenent that "TVA believes that this event resulted from past programmatic weaknesses that had been previously recognized and for w11ch extensive corrective actions had already been implemented or initiated." Although NRC acknowledged that TVA had taken extensive programmatic corrective actions for some of the problem areas, it is not clear that all areas of concern were previously identified or corrected.
Examples include the deficiencies in the emergency operating procedure revision process and the evaluation and promptness of corrective action in regard to the pump differential pressure data on Unit 1.
l The responses directed by this letter are not subject to the clearance procedures of the Office of Management and Budget as required by the Paperwork Reduction Act of 1980, Pub. L. No.96-511.
In accordance with 10 CFR 2,790 of the NRC's ' Rules of Practice " Part 2 Title 10,CodeofFederalRegulations,acopyofthisletterandtheenclosurewill be placed in the NRC Public Document Room, Sincerely, glM 2% +,
