SUBJECT:
NOTICE OF VIOLATION (INSPECTION REPORT NOS. 50-269/88-34, 50-270/88-34 AND 50-287/88-34)
This refers to the the Nuclear Regulatory Commission (NRC) inspection conducted at the Oconee Nuclear Station on November 15 - December 16, 1988. The inspec tion included a review of the inadequate performance capability of the Lee Station Transmission System, the circumstances involved in the discovery of the issue and the corrective actions. This issue was identified by you as a result of your review of electrical and mechanical system calculations for completeness in response to the NRC safety system functional inspection (SSFI)
in 1986. The report documenting this inspection was sent to you by letter dated December 30, 1988. NRC concerns relative to the inspection findings were discussed in an enforcement conference held on January 6, 1989. The letter summarizing this conference was sent to you on January 27, 198 The violation described in the enclosed Notice of Violation involved a significant failure to ensure that the emergency backup power supply via the Lee Station gas turbines could perform its intended funtion under all postulated accident scenarios due to a design deficiency. This violation resulted from a failure to adequately consider the effects of a 1979 modification that added motor driven emergency feedwater pump loads to emergency backup power supply. Speci fications and calculations were not adequate to demonstrate that the original plant design regarding the capability of the Lee Station Transmission System was maintaine In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," "10 CFR Part 2, Appendix C (1988), the violation described in the enclosed Notice has been classified as a Severity Level III violatio Normally, a civil penalty is considered for a Severity Level III violatio However, after consultation with the Director, Office of Enforcement, and the Deputy Executive Director for Nuclear Materials Safety, Safeguards, and Operations Support, I have decided that a civil penalty will not be proposed in this cas No civil penalty is being proposed to encourage your aggressive pursuit of future problems and in this case because the design deficiency identified with the Lee
. transmission line was the result of your internal followup from the NRC SSFI inspection; once the design deficiency was identified, your corrective actions were prompt and comprehensive; and routine surveillance or quality assurance activities would not have detected this situatio C)3200C187 890228 PDR ADOCK 050002 PDC
