Calculation and Optimization of Plasma Processes of Utilization and Immobilization of Silts in Low Radioactive LRW Storage Pools

Abstract

This work demonstrates the results of the research of plasma utilization and immobilization process using model silts of liquid radioactive waste (LRW) storage pools. The silts have the form of optimal water organic inflammable compositions. Also, the possibility of the application of magnetic separation for the effective extraction of solid utilization products from water suspension is shown.

Research of Possibility of Sludge Complex Recycling in Low Radioactive LRW Storage Pools

“…During the exploitation of special equipment at NFC enterprises the enormous amount of liquid radioactive wastes (LRW) with sludge in storage pools has been accumulated. The sludge consists of [1] water (60÷95%), iron (3÷17%), silicon (2.8÷8,5%), calcium (0.2÷3.2%), magnesium (1÷2.8%), sodium (0.7÷1.9%) and phosphorus (0.1÷0.9%).…”

“…According to [1], the plasma recycling of wastes in form of optimal water organic inflammable compositions (WOC) with the adiabatic combustion temperature about 1200°С provides its effective environmentally safe utilization.…”
