> Research activities in B-Cell included test projects for waste vitrification (the transformation of a substance into glass) and grouting methods for stabilizing highly radioactive materials. A report by Pacific Northwest National Laboratory in 1993 referenced a large spill of concentrated cesium and strontium into the cell. Other smaller spills also have occurred. > a visible breach was identified in the stainless steel liner at the floor of the sump, which is believed to have occurred at some point in the past operation of the facility. Some contaminated material might have historically leaked through the breached liner and concrete floor through corrosion or by following an expansion joint or crack in the concrete floor slab.
