Attention: Mr. David W. Cockfield
Vice President, Nuclear
Gentlemen:
Subject: NRC Inspection of the Trojan Nuclear Plant
This refers to a special inspection conducted by Mr. R. C. Barr and Mr. J. F. Melfi
cf this4 office from July 12, 1989 through August 8,1989, of activities
authorized by NRC License No. NPF-1, and to the discussion of our findings
held by Mr. Barr and.Mr. Melfi with Mr. Cockfield and other members of your
staff periodically during the inspection.
Areas examined during this inspection are described in the enclosed inspection
report. Within these areas, the inspection consisted of selective
examinations of procedures and representative records, interviews with
personnel and observations by the inspectors.
Based on the~ results of this inspection, it appears that certain of.your
activities.were not conducted in full compliance with NRC requirements.
Specifically, the inspection determined.that debris in the containment
recirculation sump, as well as missing and damaged sump screens rendered the
Further, this deficiency would likely have prevented both
trains of the Emergency Core Cooling System from functioning as required had
the equipment actually been called upon during the recirculation phase of a
loss of coolant accident. The safety significance of these conditions and the
high potential that a problem could occur, are best demonstrated by your own
experience in 1980, when a Residual Heat Removal pump was found to be Jamed
due-to a piece of weld rod between the impeller ring area and casing ring.
.
Our inspection also determined that your actions from many previous occasions,
when debris was found in the containment recirculation sump, were not adequate
to prevent recurrence. Furthermore, the containment recirculation sump condition
went undetected because your surveillance activities were not adequate to verify
sump cleanliness or selected design features. Additionally, there were several
other opportunities, e.g., Design Basis Document reconstitution and followup
on Generic Letter 85-22, for PGE personnel to find the problems and initiate
resolution.
Your inability to learn from these previous opportunities causes
us serious concern.
Finally, our inspection findings indicate that PGE management oversight of
plant activities associated with the sump have been ineffective. Specifically,
management had not. assured that PGE personnel were aware of the safety

appropriate sensitivity and conservative instincts needed to identify serious

challenges to safety-related equipment.
- PGE management should ensure prompt and effective action is taken to correct
the individual as well as programmatic deficiencies identified in this report.
These matters will be discussed with you during a management meeting to be
arranged in the near future. The apparent violations of NRC requirements
-
described in the enclosed report will be the subject of future correspondence. .

In accordance with 10 CFR 2.790(a), a; copy of this letter and the enclosure
will be placed in the NRC Public Document Room.

Should you have any questions concerning this inspection, we will be pleased
,
to discuss them with you.
