Gentlemen:
l
This refers to the special onsite review conducted by the NRC Augmented
Inspection Team composed of Messrs. W. D. Shafer, W. J. Kropp, S. G. DuPont,
and J. A. Hopkins of this of fice, Mr. S. .P. Sands, and S. Diab of the Of fice
l
of Nuclear Reactor Regulation (NRR), E. A. Trager, Jr., Office for Analysis
_
,
and Evaluation of Operational Data (AEOD) and J. L. Harbour, of Idaho National
Engineering Laboratory (INEL) on Octvber 4-6, 1990, of activities associated
3
with the October 4, 1990, loss of-reactor coolant' system inventory event at
'
the Braidwood Station, Unit 1, Operating License No. NPF-72, and to. the-
'
discussion of our findings with Messrs. Kr L. Graesser, K. L. Kofron, and
others of your staff at the conclusion of the inspection,
j
The enclosed copy of our Augmented Inspection Team report identifies areas
3
examined during the inspection. Within these areas, the inspection consisted
i
of a selective examination of procedures and representative records,
,
observations, and interviews with personnel,
j
.
No violations of NRC requirements.were identified during the course of this
j
inspection; however, the major purpose of~the AIT was to perform onsite fact
finding regarding the event.
Issues identified by the AIT may be examined for
possible regulatory violations in subsequent inspections. We are, however,
concerned with the lack of command and control demonstrated by the operating
crew during the March 18, 1990, loss of inventory event.and again during the
October 4, 1990, event. The corrective actions implemented as a result of the
first event were apparently not sufficient to= prevent a similar. occurrence.
-
In this regard, we plan to meet with you to discuss the corrective actions
you have or will implement as a result of the concerns identified (Section
i
VII of the enclosed report) during the AIT 1nvestigation and the results of
your own investigation. We will contact you to schedule.this meeeting once we
have received the results of your investigation and conclusions.
f
The AIT also concluded that while the October 4,1990 loss of inventory event
~
was not an intersystem loss of coolant accident (ISLOCA), the act of
conducting multiple surveillances on systems with a low /high pressure,
5
interface, coupled with the loss of command and control by the Operations
Department, is considered a precursor to an ISLOCA. We request that you-be
prepared to discuss this matter in our forthcoming meeting.
