CSER 96-013: Cementation Process, glovebox HA-20MB at PFP

This evaluation provides criticality safety controls for the cementation processing in Glovebox HA-2OMB at the Plutonium Finishing Plant. Slag and crucible residues from Pu button making will be blended with Portland cement in 5k-in. diam. x 7-in. tall cans, for eventual disposition in special DOT 17C drums. A maximum of 180 g Pu is allowed per liquid-bearing container (mixing bowl, filter funnel, or cement can). In this SD revision, three separate areas with 500 g Pu limits each are established; the airlock cell for input S&C cans, the reaction- and mixing-process area, and a cemented-can storage area. Number and spacing of containers within an area is not restricted, for areas spaced 6 inches apart. Acid addition in the reaction stage is allowed to the extent that plutonium dissolution will not occur
