Gentlemen:
SUBJECT: MCGUIRE' AUGMENTED INSPECTION TEAM (AIT) REPORT
This refers to the special, onsite inspection conducted by the NRC Augmented
Inspection Team (AIT) during the period March 8-11, 1989.
The inspection
included a review of the events related to the "B" steam generator tube failure
on - March 7,
1989, and subsequent recovery.
At the conclusion of the
inspection, the findings 'were discussed with those members of nur staff
identified in the enclosed inspection report.
~ The AIT concluded that the tube failure did not result in a radiological
l
release to .the environment that exceeded regulatory limits or exceeded a
Technical Specification Safety Limit.
The operating crew performed adequately
and they knew which procedure contained the actions or steps needed to
mitigate this event.
However, the procedures were found to have significant
weaknesses which could result in unnecessary releases of radioactivity to the
environment should future steam generator tube rupture events occur.
The
mitigative strategy which McGuire used for coping with this event deviated'
substantially from the Westinghouse Owner's Group Emergency Response
Guidelines.
This was related to you in my letter of March 21, 1989,
concerning McGuire Nuclear Station Emergency Procedures, along with a request
for you to reevaluate these differences and document their justification for
our inspection by June 30, 1989.
We are also concerned with operators lack of
confidence that certain systems would function as designed.
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.
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.
