FIELD: power engineering. ^ SUBSTANCE: protective chamber for processing a material preferably in the form of a powder, granules and/or pellets, which contains civil or weapon plutonium in the form of plutonium oxide, carbide and/or nitride and may contain other actinides, for instance, americium, neptunium or curium, having an outer border and a base. The protective chamber has multiple separate subcritical gaps (603) to catch spilled material containing plutonium, which are arranged on the base, and also under appropriate conditions at the outer border. ^ EFFECT: invention makes it possible to efficiently prevent criticality at plants. ^ 9 cl, 11 dwg |
