Plasma Processing of Fuel Pellets

The plasma technology for producing powder from fuel-rod fuel that failed an engineering requirements audit is validated. The fundamentals of nucleation of a steam–gas system under different conditions are analyzed. The structure of dispersed particles formed during cooling of low-temperature plasma...

Description
Summary:The plasma technology for producing powder from fuel-rod fuel that failed an engineering requirements audit is validated. The fundamentals of nucleation of a steam–gas system under different conditions are analyzed. The structure of dispersed particles formed during cooling of low-temperature plasma is shown for a mixture of uranium and plutonium dioxides. Methods for controlling the size of these particles are substantiated. It is shown that the most effective of the available methods are cooling rate reduction and use of weak external magnetic fields.
