IE Bulletin (79-BU-02):
Pipe Support
Base Plate
Designs
Using
Concrete
Expansion
Anchor Bolts.
The Bulletin was issued to address
problems at nuclear
plants regarding
concrete
anchor bolts.
The inspector
reviewed the licensee's
response
to the Bulletin and ver-
ified, by reviewing documentation,
gC records,
and by measuring
and exam-
ination of selected
installed bolts, that the actions required
by the
Bulletin were met and that the bolt marking system accurately identified
the bolt length.
Based
on the above, this item is considered
closed.
(Closed) Violation (410/86-13-03):
Pipe supports with no measurable
gap.
The
NRC found two Scram Discharge
supports,
lA and
11A, had
no
measurable
gap.
The licensee's
response
to the violation reported that
a
surveillance
performed
by
SWEC identified a third support,
18B, with a
similar problem.
The licensee further reported that the three
supports
were repaired
and the deficient gaps
were corrected.

The inspector
reviewed the licensee's
response
to the violation,
gC re-
cords
and,
in addition,
independently
measured
the
gap in each of the
three
supports
to ascertain
that the repairs
were effective.
He found
that the originally deficient gaps
were properly repaired
and meet appli-
cable
gap requirements.
Based
on the above this item is considered
closed.
(Closed) Violation (410/86-13-01):
Rigging of equipment to safety related
components.
The

improperly rigged to safety related
components
in the plant.
The inspec-
tor verified, through
a review of records,
that the corrective
and pre-
ventive actions
by the licensee

He found that the re-
quired evaluation

manufacturer,
which states
that in small dampers,
