Plutonium Recovery from Spent Glass-Paper Filters Used for Fine Purification of Air

Atomic Energy Aims and scope

Abstract

The development of a technology for extracting plutonium from spent glass-paper filters used for fine purification is investigated. Two technological schemes are developed. They include nitric-fluoride-acid treatment of glass-paper in a mixture of nitric and hydrofluoric acids and preliminary alkaline treatment of the glass-paper followed by nitric-fluoride-acid leaching of plutonium from the pulp by a mixture of nitric and hydrofluoric acids.

The technology proposed will make it possible to obtain secondary waste (with respect to plutonium content) and insoluble residues, which will then be utilized by well-known technological techniques: monolithization, vitrification, and others.
