SUBJECT: -NOTICE OF VIOLATION (NRC INSPECTION REPORT N05. 50-338/89-08 AND 50-339/89-08, 50-338/89-14 AND 50-339/89-14)
This refers to the Nuclear Regulatory Commission (NRC) inspections conducted on March 21 - April 17, April 25 - May 3,1989, and April 18 - May 31,1989, at the North Anna facility. The inspections included a review of the adequacy of service water supply to the safety-related recirculation spray system during accident conditions, and the facts and circumstances surrounding the Unit I reactor vessel level perturbations on April 26 and 27, 198 The reports documenting these inspections were sent to you by letters dated May 17, 1989, and June 29, 1989. As a result of these inspections, significant failures to comply with NRC regulatory requirements were confirmed, and accordingly, NRC concerns relative to the inspection findings were discussed in an Enforcement Conference held on May 24, 1989. The letter summarizing this Conference was sent to you on June 23, 198 Violation A of the enclosed Notice concerns the operability of the containment recirculation spray system. Your service water performance test conducted on April 14 and 24, 1989, for Units 1 and 2 respectively, showed actual service water flow to three of the eight recirculation spray heat exchangers (RSHX) to be' below the design basis flow. The identification of the above problem follows jour identification and correction, in 1988, of other problems which could have reduced the heat transfer capability of the RSHX, including biological fouling factors greater than those assumed in the design basis accident, and service water pump and component cooling water heat exchanger configurations that would u have prevented achieving the designed service water flow to the RSHX during design basis accident conditions. These problems, combined with the most recent finding that the service water throttle valves were incorrectly adjusted, had the potential for preventing the recirculation spray system from performing its intended safety function and demonstrate that the plant staff did not have a proper understanding of the plant design basi In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions, "10 CFR Part 2, Appendix C, 53 Fed. Reg. 40019 (October 13, 1988) (Enforcement Policy), violation A described in the enclosed Notice has i o_e h D

i been classified as a Severity Level III violatio Normally, a civil penalty l is assessed for a Severity Level III violation. However, in recognition of your identification of the problems and your extensive corrective actions, after consultation with the Director, Office of Enforcement, and the Deputy Executive Director of Nuclear Material Safety, Safeguards, and Operations Support, I have decided that a civil penalty will not be propose Violation B of the eticlosed Notice involves your failure to provide adequate i
procedures to control the Unit I reactor vessel inventory during reactor vessel head purging operations. Although classified as a Severity Level IV violation, events such as this one can, under different circumstances, have potentially serious consequence You are required to respond to this letter and should follow the instructions specified in the enclosed Notice when preparing your response. In your re-sponse, you should document the specific actions taken and any additional actions you plan to prevent recurrence. After reviewing your response to this Notice, including your proposed corrective actions and the results of future inspections, the NRC will determine whether further NRC enforcement action is necessary to ensure compliance with NRC regulatory requirement In accordance with Section 2.790 of the NRC's " Rules of Practice," Part 2, Title 10, Code of Federal Regulations, a copy of this letter and its enclosure will be placed in the NRC Public Document Roo The responses directed by this letter and enclosed .
