The concrete was batched as normal and trucked to the site. The specified slump was low and consistent with requirements to help reduce slippage on the sloping dome.
Early placement was done by bucket but the inspector was informed that later placement was performed by pumping.
The pour number was IR-102, Reactor 1 dome, eight inch slab.
The mi.v was designated as BA-5500 - five ounce DRX.
The inspector observed QC personnel at the batch plant, unloading station and at the work site.
In addition, a spot check of the pour tickets, concrete field tests and temperature measurements indicated the concrete was being batched in accordance with the job apecification.
