Observation of concrete at the pump delivery point disclosed
the following
noncompliance.
Specification
CAR-SH-CH-6, paragraph
12 states
"Each truck
shall
be equipped with an accurate
revolution counter".
Truck number
30
did not have
a working revolution counter at 6:00 p.m.
A subsequent
check
by the inspector at 6:30 p.m.
showed the revolution counter
was repaired.
Failure to have
a working revolution counter
was identified to the licensee
as

401/79-07-04,

and 403/79-

"Concrete
Truck Revolution Counters".
Since the inspector
observed
that the concrete
was placed within the specified time and since acceptance
of pumped
concrete is based
on
QC inspection at the point of placement
rather than the truck delivery point to the
pump this item is considered
to
be a deficiency.

The inspector
observed partial placement
of impervious fill in the west
auxiliary dam core trench
and results of filloperations in the separating
dike.
Acceptance criteria examined by the inspector were:
a.
PSAR Appendix 2E
b.
CAR-SH-CH-4, "Embankments,
Dams, Dikes and Channels"
c.
Procedure TP-08, Soil Control Program - Class I Dams, Fill and Backfill"
d.

Observations
indicated that impervious fills are being placed with field
control
methods
which permit
the moisture
content
to vary from plus or
minus
4 percent
of optimum.
Appendix
2E of the
and Specification
CAR-SH-CH-4 state
embankment
cores shall be placed to within plus or minus
2 percent
of optimum moisture content.
As discussed
in paragraph
3, this
was identified to the licensee
as an item of noncompliance.
During discussions
on safety
related fills (fills placed
in around
or
against
Category I structures)
on April 18 between licensee
representatives
and
NRC representatives
from NRR and Region II I&E, the licensee
indicated
that
a review of his records
showed impervious fillin the separating
dike
had
been
placed
at moisture
contents
outside of specified limits.
The
licensee
indicated
he
was generating
a nonconformance
report and that fill
operations
were stopped.
Subsequent
to the inspection,
on April 19,
Region II I&E discussed fill
operations with licensee
management
by telephone.
The licensee
stated that
he would discontinue placing of all safety related fills until procedures
and specifications
have been revised to permit control of specified compaction
limits. Evaluation of fills placed outside specified limits villbe reviewed
by NRC I&E RII and NRR.
