SUBJECT:
INSPECTION REPORT NO. 50-282/98005(DRP); 50-306/98005(DRP) FOR
PRAIRIE ISLAND NUCLEAR GENERATING PLANT
Dear Mr. Wadley:
On March 28,1998, the NRC completed an inspection at your P uirie Island Nuclear Generating
-
Plant. The enclosed report presents the results of that inspection.
During the four week period covered by this inspection, most operations activities were
performed well with only a few mmor errors. Two evolutions involving unusual reactivity
manipulations on Unit 1 were conducted conservatively and carefully. The Unit 2 startup and
retum to full power was also accomplished in a safe and controlled manner. Several instances
of personnel stopping to correct procedure discrepancies were noted. Most maintenance and
surveellence activities were also conducted well. However, one instance of improper foreign
material exclusion control and one case of a work order not being property revised were noted
in addition, a temporary change to equipment operating instructions necessary to protect a
gauge from being damaged was not incorporated into all of the appropriate procedures. Finally,
an inadequate procedure for setting thermal overload heaters resulted in a ventilation fan being
inoperable at the same time the opposite train's emergency diesel generator was being tested.
Engineering support of operations and maintenance activities was excellent.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter and its
enclosure will be placed in the NRC Public Document Room.
Sincerely,
/s/ Marc L. Dapas for
Geoffrey E. Grant, Director
Division of Reactor Projects
