I'm assessing criticality safety of a waste removal plan for a (theoretical) abandoned russian laboratory. In the laboratory plutonium was recovered from fuel rods. The room is mainly empty except for a dissolver, a sump below the dissolver and spilled metal chips on the floor. The dissolver contains fissile material, nitric acid and debris at the bottom. It can be filled from the top and has a tap at the bottom. The sump is filled with raschid rings and contains boron and plutonium nitrate.
I need to come up with a plan to drain and decontaminate safely the dissolver and sump so the room is ready for demolition. There are no roads in the arctic so any waste must be stored appropriately.
Basically, I'm in need of some case studies or literature so I can make a reasonable attempt at a plan.
My main questions are:
What can I use to accurately characterise the waste in the dissolver and sump?
How do I remove the fissile materials and nitric acid safely from the dissolver and sump?
What do I use to store the wastes?
Some random sources of information I have found:
