Appl. No.:

6/905895

Inventors:

Eugene E. Smeltzer - Salem Township, Westmoreland County PA
Michael C. Skriba - Plum Boro PA
Keith K. McDaniel - Ellicott City MD

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

G21F 908
G21F 914

US Classification:

252632

Abstract:

A process is described for reducing the volume of spent ion exchange resins containing radioactive contaminants, and a filter aid having groups reactive with the functional groups of the resins. Spent ion exchange resin and the filter aid are dewatered, then subject to a pressure of about 2000 psi in conjunction with 250. degree. C. heat to reduce the volume occupied by the resin by up to a factor of 5 and impart rewet stability.

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

B65B 304

US Classification:

141 65

Abstract:

Described is an apparatus for removal of liquid from a waste burial container holding a slurry of waste material. Constructed inside the container are multiple layers of porous plastic pipe having pores of predetermined size and having the pipe extend radially from a central hub. The porous plastic pipe is supported internally by a sleeve in contact with the pipe inner wall at the pipe's hub end and a rod of smaller diameter running the length of the pipe. The hubs rest on plates that are affixed to vertical supports. Each hub is connected to a liquid removal system that includes piping and a header for applying a vacuum to draw the liquid from the slurry.

US Classification:

423277

Abstract:

A process is described for the solidification of concentrated boric acid waste solutions. The waste solution must have a boric acid concentration greater than 30% by weight. Sodium metasilicate is added to the boric acid waste solution and is mixed; a dry, hard product is formed. The process is not hindered by the presence of up to 40% dewatered bead resins.
