SUBJECT:
(NRC INSPECTION REPORT NOS. 50-269/98-03, 50-270/98-03,
50-287/98-03)
Dear Mr. McCollum:
The Nuclear Regulatory Commission (NRC) conducted a Safety System Engineering
Inspection (SSEI) at your Oconee 1, 2, and 3 reactor facilities during
March 2 - 6 and March 16 - 20, 1998. The primary objective of this SSEI was
.
to assess the calculations, analyses, and other engineering documents that
were used to support control room ventilation system (CRVS) and penetration
room ventilation system (PRVS) performance during normal and accident or
abnormal conditions. The enclosed report presents the results of that
inspection.
Based on the results of this inspection, the NRC has determined that
violations of NRC requirements occurred. Violations were identified for
untimely reporting of design issues; incorrect and nonconservative assumptions
in control room operator dose calculations; and failure to perform penetration
room ventilation system surveillances in accordance with the Technical
Specifications. We are concerned that your procedures for operability and
reportability incorrectly allowed the untimely reporting of design issues. We
are also concerned that your engineering calculations contained significant
incorrect assumptions.
These violations are cited in the enclosed Notice of Violation, and the
circumstances surrounding the violations are described in detail in the
enclosed report. Please note that you are required to respond to this letter
and should follow the instructions specified in the enclosed Notice when
preparing your response. The NRC will use your response, in
part, to
determine whether further enforcement action is necessary to ensure compliance
with regulatory requirements.

In addition, two apparent violations were identified and are being considered
for escalated enforcement action in accordance with the "General Statement of
Policy and Procedures for NRC Enforcement Actions" (Enforcement Policy),
NUREG-1600. The apparent violations involve a safety evaluation for a 1984
modification to the Unit 1 and 2 control room ventilation system and a 1997
Updated Final Safety Analysis Report (UFSAR) change for that modification.
Accordingly, no Notice of Violation is presently being issued for these
inspection findings. In addition, please be advised that the number and
characterization of the apparent violations described in the enclosed
inspection report may change as a result of further NRC review.
A predecisional enforcement conference to discuss these apparent violations
has been scheduled for 10:00 a.m.-EDT on May 19, 1998, in the NRC Region II
Office. 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 violation sooner, corrective actions,-significance of
the issues, and the need for lasting and effective corrective action. In
particular, we expect you to address how your corrective action process and a
UFSAR change missed opportunities in 1997 to identify and correct a single
failure vulnerability related to the ventilation for the cable rooms. Your
letter of April 12, 1995, described a plan to review quality assurance (QA)
classifications for all non-safety related equipment relied upon to mitigate a
design basis accident. Please address why that review failed to change the QA
classification of the cable room ventilation to QA-1 (safety-related) or to
identify and correct the single failure vulnerability. 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 violation, 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.
The conference will be open to public observation in accordance with Section V
of the Enforcement Policy (Enclosure 3).
You will be advised by separate correspondence of the results of our
.
deliberations on this matter. No response regarding these apparent violations
is 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 enclosures will be placed in the NRC Public Document Room
(PDR).
