SUBJECT:
NRC SPECIAL INSPECTION REPORT 50-269/97-07, 50-270/97-07, AND
50-287/97-07
Dear Mr. Hampton:
On June 6, 1997, the NRC completed a special inspection at your Oconee Nuclear Station.
This special inspection focused on the integrated efforts of your staff to investigate the
causes and to provide corrective actions for an unisolable reactor coolant leak detected
April 21, 1997. The enclosed report presents the results of that inspection.
Based on the results of this inspection, two apparent violations were identified and are being
considered for escalated enforcement action in accordance with the "General Statement of
Policy and Procedure for NRC Enforcement Actions" (Enforcement Policy), NUREG-1600.
The first apparent violation concerns the failure of your augmented inservice inspection
program, established after previous high pressure injection line cracks were identified, to
identify and correct precursors to high pressure injection line cracking. Periodic augmented
inspections intended to detect the cracks or their precursors were not satisfactorily
implemented, and conditions indicative of cracking went unrecognized from tests conducted
in 1996 until a crack resulted in an unisolable reactor coolant leak on April 21, 1997. The
second apparent violation concerns a lack of appropriate actions to assure that measured
temperature differentials, indicative of thermal stratification in the high pressure injection
lines, identified in June 1990, were evaluated or corrected. Evidence of thermal stratification
affected previous assumptions used in developing corrective actions for high pressure
injection pipe cracking. No Notice of Violation is presently being issued for these inspection
findings. In addition, please be advised that the number and characterization of apparent
violations described in the enclosed inspection report may change as a result of further NRC
review.
An open predecisional enforcement conference to discuss these apparent violations has been
schedule for July 23, 1997, at 10:00 a.m. The decision to hold a predecisional enforcement
conference does not mean that the NRC has determined that a violation has occurred or that
enforcement action will be taken. This conference is being held to obtain information to
enable the NRC to make an enforcement decision, such as a common understanding of the
facts, root causes, missed opportunities to identify the apparent violations sooner, corrective

actions, significance to the issues and the need for lasting and effective corrective action. In
addition, this is an opportunity for you to point out any errors in our inspection report and for
you to provide any information concerning your perspectives on 1) the severity of the
violations, 2) the application of the factors that the NRC considers when it determines the
amount of a civil penalty that may be assessed in accordance with Section VI.B.2. of the
Enforcement Policy, and 3) any other application of the Enforcement Policy to this case,
including the exercise of discretion in accordance with Section VII.
You will be advised by separate correspondence of the results of our deliberations on this
matter. No response regarding these apparent violations are required at this time.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter and
its enclosure will be placed in the NRC Public Document Room.
Sincerely,
