FIELD: conversion of gun plutonium into fuel. SUBSTANCE: invention makes it possible to stabilize residual gallium content when converting alloy into plutonium dioxide. Gallium-plutonium alloy is dissolved in melt of alkali metal chlorides, chlorine being bubbled through melt. Plutonium dioxide is deposited with oxygen-chlorine mixture. Chlorine content in mixture varies from 0.005 to 5% by volume. Plutonium dioxide deposit is washed to remove salt with 0.1 mole/l of nitric acid solution and dried. Gallium content in plutonium dioxide powder is (19-2210. 10-4%. EFFECT: more efficient conversion method. 1 tbl
