The inspector
observed
work activities in progress,
completed work and
plant status
in several
areas
of the plant during
a general
inspection
of Units
1 and 2.
The inspector
examined work items for obvious
defects
or noncompliance with NRC requirements
or licensee
commitments.
Particular note
was, taken regarding
the presence
of quality control in-
spectors
and indications of quality control activities through visual
evidence
such
as inspection
records,
material identifications,
nonconformance
and acceptance
tags.
In addition, the inspector
interviewed craft and
supervisory
personnel
encountered
in the work areas.
No items of noncompliance
were identified.

equipment
and panels.
The inspector
reviewed the revision to the Field Procedure
FP-E-10 which was modified
to include separation
external
to electrical
panels/equipment.
However,
the licensee's. corrective action does not address
existing separation
violations nor action to be taken to preclude further noncompliances.

Item 387/ 81-01-02
ertaining to maintenance
and
survei
ance of e ectrical
pane s/equipment in storage.
The inspector
reviewed the licensee's
program for maintenance/surveillance
of storage
requirements for stored equipment.
The
inspector determined that
implementation of the program (consisting of scheduled daily surveillance
by elevation
and areas)
appeared
to be inadequate.
The inspector
examined
areas
30 and
32 at elevation 683'-0 of Unit 2.
Panel
Nos.
2C0201,
2C022 and
2D274 were not heated

In addition, the
protective cover for 2C021
was tom in several
places,
exposing the
panel to dirt and dust.
Construction
personnel
stated this area
had
been inspected earlier that morning.
This item remains 'open.

Electrical
Cables
and Terminations
- Work Observations
The inspector observed
work performance, partially completed
work and
completed work, as appropriate,
relative to select cables,
raceways
and conduit to determine whether the requirements
of applicable specifications,
work procedures
and inspection
procedures
are being accomplished
in
accordance
with NRC requirements
and licensee commitments.'reas
examined include handling,
use of specified materials,
routing, separation,
and
QC inspections.

For this determination
the inspector witnessed
cable pulls (Unit

Section 2.3.4 of drawing E-49,
sheet

10 on conduit and
cable tray Notes
and Defects states,
in par t, that:
"The minimum
separation
distances
required
between totally enclosed
raceways
located in areas
not subject to fire.
. .or mechanical
damage
shall
be as follows:
2.3.4. 1
One inch minimum between
class
IE wireways,
cable trays
or conduits.
2.3.4.2
One inch minimum between
class
IE wireways,
cable trays
or condui ts and simi liar non-class
IE raceways.
The licensee
was informed that this is an item of noncompliance
and
a violation of 10 CFR 50, Appendix 8, Criterion
Ijt.
50-
387/81-12-01;
50-388/81-06-01
For this determination
the inspector
examined electrical
grounding
between trays/conduits.

The inspector observed that the electrical
ground conductor
(No.
4/0) was attached
to the side of tray No.
FIPF07 (el 670, Area
28) for a distance of 6 ft then crosses
over at right angle
adjacent parallel conduits
coming into contact with conduit Nos.
FIP479 (green)
EIK995 (red)
and the non-g fire line conduit.
This installation
has the effect of reducing the
1 inch separation
to 1/2 inch.
Placement of the electrical
ground between
the tray
and the conduit appears
to defeat the purpose of maintaining the
required
1 inch separation
between
the tray and conduit.
The
1
inch air gap has
been determined
as the minimum separation
requirements
to prevent
damage
from overheating
to adjacent
raceways/conduits.
Discussions
with licensee
.and construction
personnel
indicate
this concern
was not addressed
in installation procedures
or
instructions.
This item is unresolved
pending
NRC review of licensee resolution
and corrective action (50-387/81-12-02;
50-388/81-06-02).

test results indicating 10-12/ conductor
failure rate.
Based
on the above test results
the licensee
is removing all
damaged
D-11 cable in trays
and conduits.
In addition,
cable~s
adjacent to the damaged
D-11 cables (in conduits only) are also
being replaced.
The licensee is not purchasing
any more D-11 cables.
Existing D-
11 cables in storage will be used
on Unit 2, but only if the
cable runs in trays/conduit is less
than
50 ft.
The inspector
had no further questions.

Work Observations
The inspector
observed
work performance, partially completed work and
completed work, as appropriate,
relative to the instrument
components
selected
below and related
equipment to determine
whether the require-
ments of applicable specifications,
work procedures
and inspection
procedures
are accomplished
in accordance

Items examined for this determination
include:
No.

The inspector
noted that the solenoid valve no.
SV-27534A for Damper
No.
HDM-27534A appeared
to have
had its flex-conduit connection cut
and
on the floor with the valve.
Solenoid valve No.

missing
and appeared
to have
been
taken
from the damper control unit

QC personnel
with the .inspector indicated it was
common
practice to remove
components for use in other areas
to meet turnover
schedule
dates.
The inspector also observed that although the sole-
noid valves
noted above are
non-Q and are being
used in safety related
systems
none of the components
referenced
were tagged to identify the
non-conforming component.
Section 4.4. 1 of Field Procedure
FIP-G-3,
on Hold Tags,
states,
in
part:
".
.
.The Quality Control Engineer shall
prepare
a hold for QC

. ;The
tag shall
remain
on the item until
a disposition
has
been
implemented
and the re-inspection
accepted
