Concrete Placement
2
The inspector performed a surveillance of concrete pours of reactor
building (outside CTW-20, Traveler 1246) and diesel generator build-
ing roof and 737 level equipment pads (1.raveler 1197).
The following conditions were noted:
(1) The forms were secure and leak tight prior to the placement.
(2) The preplacement inspection had been completed and was in order
for pour CTW 20.
The inspector noted that the traveler 1197 for
the 737' level equipment pad pour was not completely signed off
and concrete placement was in progress.
Investigation revealed
that the situation was one of Quality Control oversight and was
not typical of normal operation. The inspector will follow this
area and has no more questions at this time.
(3) Quality Control inspectors were assigned to perform periodic
concrete testing. Numbers were adequate.
(4) Concrete testing was performed at the required frequencies.
(5) Adequate numbers of crews and personnel were assigned to make
the placement.
(6) Surrounding equipment was protected from any concrete spill
during placement.
-(7) Delivery and placement were satisfactory.
Concrete was pumped
to the placement area and deposited via a flexible boot which
adequately confined the concrete to a minimum fall to prevent
segregation.
(8) Concrete was observed to be properly consolidated using internal
concrete vibrators. The vibrators were randomly checked while
operating in the concrete. Vibrator technique was satisfactory.
No items of noncompliance or deviations were identified.
3.
Inspection of Material / Component Laydown Areas
The resident inspector performed a followup surveillance of pipe,
electrical, and reb.r laydown outside storage areas. The inspec-
tion was in relation'to the requ'.rements of ANSI N45.2.2: material
protected and stored off the ground, caps on pipe ends, and segrega-
tion of safety and non-safety material. Much improvemt.nt had been
l
made since the April report. The electrical laydown area had been
cleaned up and was satisfactory.
Pipe laydown was improvdi with ail
caps on, and ends protected. The rebar area showed marked improvement
with scrap removed and rebar moved off the ground and separated.

No items of noncompliance or deviations were identified.
4.
Inspection of Power Block Areas
The inspector performed numerous inspection tours of the Reactor Fuel
and Auxiliary Buildings.
Inspection was for housekeeping, fire
hazard, and protection of safety related materials. The below ground
floors of the Auxiliary and Fuel Buildings had numerous examples of
safety related pipe laying on the floor, some in water, and examples
of trash and wood piled in arets conductive to fueling a fire. These
two areas were the greatest offenders. Management was notified and
took prompt action. The resident inspector performed followup in-
spections and noted that the area is in satisfactory condition at
this time. Future followups will be performed.
No items of noncompliance or deviations were identified.
5.
CRD Penetration Work Activity
The inspector performed a surveillance of the Reactor Building con-
trol rod drive (CRD) penetration rework activity. Due to some past
inferior welds, the constructor has been attempting to remove some
35 control rod drive tubes installed in the concrete drywell wall.
Existing job instructions covered specific numbered tubes to be
stress relieved and removed by pipe drilling. Adjacent to the CRD
tubes, a 3" exploratory hole was drilled through the exterior wall
plate, parallel to the tubes, cutting through rebar, and jamming
three feet into the concrete drywell wall. This operation was per-
formed without written approved instructions or an approved design
change.
This item is considered in noncompliance with the requirements of
Criterion V of 10 CFR 50, Appendix B (461/80-10-01).
Unresolved Matters
Unresolved n.atters are items about which more information is required in
order to ascertain whether they are acceptable items, items of noncom-
pliance, or deviations. There are no unresolved items.
Exit Meetings
The resident inspector attended an exit meeting conducted by the RIII
Inspectors Gallagher and Wescott on May 23, 1980. The inspector met
with the licensee representatives (denoted under Persons Contacted) on
May 9, 15, 27, and 30, 1980. The inspector summarized the scope and
findings of the inspections performed. The licensee representatives
