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, 1989.
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, 1989.
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
have prevented achieving the designed service water flow to the RSHX during
u
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 basis.
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

been classified as a Severity Level III violation.
Normally, a civil penalty
i
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 proposed.
Violation B of the eticlosed Notice involves your failure to provide adequate
procedures to control the Unit I reactor vessel inventory during reactor vessel
i
head purging operations. Although classified as a Severity Level IV violation,
events such as this one can, under different circumstances, have potentially
serious consequences.
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 requirements.
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 Room.
The responses directed by this letter and enclosed . Notice are not subject to
the clearance procedures of the Office of Management and Budget as required by
the Paperwork Reduction Act of 1980, Public Law No.96-511.
Snould you have any questions concerning this letter, please contact us.
