Plant Tour The inspectors made a tour of the site to observe work activities in progress, completed work and the status of construction.
The inspector examined work items for any obvious defects or noncompliances with regulatory requirements and observed QC activties and evidence of quality control of the work.
Specific activities observed by the inspectors included protection of Cadweld "B" sleeves on the B-7 containment liner (knuckle plate),
storage of reinforcing.steel and down comers, preparation for concrete placement for the reactor pedestal.
and primary containment wall, batch plant maintenance and
. concrete placement for a control building wall.
No items of noncompliance were identifie '.
