Unit 1 Control Buildin Cable Tra Four installed cable trays in the lower cable spreading room were examined for conformance with the specified requirements.
The trays were:
1EZJ2ADTR, Sections EE through EQ lEZJ2ADTY, Sections EE through EQ lEZJ2ABTR, Sections FK through FV 1EZJ2ABTY, Sections FK through FV The governing specification w'as 13-EM-303, Electrical Cable and Raceway Installation, and the applicable drawings were 13-E-ZJC-006 and -007, Control Building Conduit and Tray Plan at Elevation 120-ft. ZJ2A, and ZJ2B.
'I No deviations or items of noncompliance were identifie.
Unit 1 Containment Dome Concrete 'Records The inspector examined the placement and post-placement (curing)
records pertaining to the containment dome final concrete placement (No. 1C123-1380 cu. yds.).
The applicable inspection plans were WPP/QCI 53.0 for the placement and WPP/QCI 54.0 for post-placement.
No deviations or items of noncompliance were identified.
4.
F Unit 1 Main Steam Su ort Structure (MSSS During a tour of Unit 1, the inspector observed re ular iy spaced horizontal cracks in the exterior surface of the north wall of the MSSS between the 120 and 140-foot elevations.
Also in evidence
was cadweld filler metal tips from several cadweld sleeve tap holes.
The inspector learned that this condition had been found by Bechtel when the concrete forms were removed and had been documented on a
nonconformance report (No. CC-1662).
The situation demonstrates that the concrete cover over the No.
18 reinforcing bar is 'less than the minimum allowable thickness of 1 3/8-inches.
It is believed to have been caused by form movement during concrete placement.
Remedial action for rectifying the situation is being evaluated by Bechtel.
This item will be examined further during subsequent inspection (50-528/80-05/Ol).
5.
Unit 3 Containment Base Mat The work activities associated with the containment basemat concrete placement 3C012 and 3C013 were examined.
The quantity of concrete involved was 7,280-cu.
yds and was placed in one continuous operation.
Activities examined included foundation cleanup and preparation, aggregate handling, concrete mixing and slump measurement, concrete placement and consolidation, and finishing oporations.
The governing specification was 13-CM-365, Forming, Placing, Finishing and Curing of Concrete.
WPP/QCI 53.0 and WPP/QCI 54.0 were the applicable inspection plans for pre-placement and placement, respectively.
These documents were also examined as were a representative sample of concrete batching records, and test laboratory records for temperature and slump measurements.
No deviations or items of noncompliance were identifie.
Craftsmen Interviews The trial program of formal, private interviews with construction craftsmen involved with safety-related work was concluded.
Private discussions were h'eld with twelve (12) individuals.
None expressed any concerns about the adequacy of construction quality.
All were courteous and cooperative.
No quality-related irregularities were identified to the inspector.
7.
Plant Tours The construction site was toured several times during this reporting period.
Particular attention was given to work in progress, general housekeeping conditions, case and preservation of equipment, and general implementation of quality assurance program requirements.
No items of noncompliance or deviations were identified during the plant tours.
