FIELD: power engineering. ^ SUBSTANCE: nuclear waste is mixed with a mineral composition and water, dried to form an immobilising matrix, differing by the fact that the mineral composition is produced by a manufacturing method, including stages that consist in preparing a base containing a certain amount of mineral material synthesised at least by a part of a live structure selected from flora or fauna and/or from a number of microorganisms; and in processing the specified base for its conversion into an inactivated substance of a certain texture. ^ EFFECT: invention makes it possible to immobilise nuclear waste, which may not be immobilised with classic cementing. ^ 10 cl |
