Local Gas Purification System in Spent Nitride Fuel Oxidation

Аннотация

A local gas-purification system of the voloxidation operation is examined within the framework of the technology of regeneration of spent mixed uranium-plutonium nitride fuel from fast reactors. The system includes a metal-fabric filter, HEPA filter, ruthenium capture unit, an adsorber for capturing iodine, a unit for additional oxidation and trapping of hydrogen (tritium), and a unit for capturing ¹⁴CO₂. A description is given of each unit, the overall scheme, and the possibilities of the gas-purification system.
