International Classification:

G21F 9/30

US Classification:

588 11, 588 16, 588 10

Abstract:

The present disclosure relates to a method of consolidating a calcine comprising radioactive material, the method comprising mixing 60-80% (by weight) of a radionuclide containing calcine with at least one non-radioactive additive, such as an oxide, and hot isostatic pressing the mixture to form a stable monolith of glass/ceramic. In one embodiment, the ratio of radionuclide containing calcine to additives is about 80:20 by weight, wherein the non-radioactive additive comprises oxides such as BaO, CaO, AlO, TiO, SiOand others, that combine with the waste elements and compounds to form a ceramic mineral or glass/ceramic material, after hot isostatic pressing. Non-limiting examples of mineral phases that may be formed are: hollandite (BaAlTiO), zirconolite (CaZrThO), and perovskite (CaTiO).

Assignee:

American Isostatic Presses, Inc. - Columbus OH

International Classification:

B22F 3/15

Abstract:

There is disclosed a nuclearized hot-isostatic press (HIP) system comprising, a high temperature HIP furnace and a multi-wall vessel surrounding the furnace, such as a dual walled vessel comprising concentric vessels. The described multi-walled vessel comprises at least one detector contained between the walls to detect a gas leak, a crack in a vessel wall, or both. The disclosed HIP system also comprises multiple heads located on top and underneath the furnace, a yoke frame, and a lift for loading and unloading a HIP can to the high temperature HIP furnace. There is also disclosed a method of using such a system to provide ease of maintenance, operation, decontamination and decommissioning.
