"Clean Up Resumes At Hanford's K-Basin"
"Hanford workers found more debris sitting on the bottom the K East Basin floor than any other reactor. Workers found junk like old tools, scaffolding, even a computer monitor. Trying to vacuum up the sludge around the debris became extremely challenging.
'We started without a lot of research and characterization of what was in the basin just because records were poor,” said Pete Knollmeyer, Vice President of K Basins Closure Project. “We've encountered a lot of things we didn't expect. A lot of obstacles to overcome.'"
