SUBJECT:
NRC INSPECTION REPORT NOS. 50-369/93-20 AND 50-370/93-20
,
This refers to the special inspection conducted by the Nuclear Regulatory
l
Commission (NRC) Augmented Inspection Team (AIT) at your McGuire facility
!
during the period of September 1-5, 1993. The inspection included a review of
events surrounding a leak repair procedure that led to a steam leak inside the
primary containment. At the conclusion of the inspection, the findings were
discussed with those members of your staff identified in the enclosed report.
,
,
The enclosed copy of the AIT report identifies the areas examined during this
inspection. Within these areas, the inspection consisted of selective
,
examinations of procedures and representative records, interviews with
-
personnel and observation of activities in progress.
,
!
The AIT identified significant deficiencies in the control of maintenance
activities at McGuire Nuclear Station.
Deficiencies included inadequate
!
measures to ensure proper valve maintenance, low sensitivity to a high-risk
evolution and inadequate oversite of control room activities. Management
authorized repair of the steam leak without a full understanding of the
potential safety consequences. During recovery from the steam leak,
ineffective supervisory oversite and inattentive operators in the control room
resulted in an inadvertent heatup of the Reactor Coolant System from hot
i
shutdown (Mode 4) to hot standby (Mode 3).
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
i
will be placed in the NRC Public Document Room.
A review of the inspection findings is continuing to determine whether the
!
described activities violate NRC requirements.
You will be advised by
separate correspondence of the results of this matter. We appreciate your
cooperation during our team inspection and subsequent evaluation of this
,
event. Your openness during the inspection was very beneficial.
