1. A method for producing monophase powders of actinide salts, comprising feeding a solution of one or more nitric actinides and formic acid in a cylindrical heated reactor, thereby forming a powder, grinding the resulting powder, and discharging the grinded powder, characterized in that the solution of one or more nitric actinides and formic acid are continuously metered to the upper zone of the reactor, wherein the solution and formic acid are mixed in a thin film on a heat-exchange surface and continuously stirred by rotor blades, wherein the grinded powder is collected in a hopper by gravity.
