ABSTRACT:
An impeller mixer assembly is provided for stirring a radioactive material in a vessel having a combination of liquid and solid substances, until that combination turns into a liquid slurry that can be pumped out of the vessel. The impeller mixing assembly includes a folding blade assembly for stirring the radioactive material in the vessel. The folding blade assembly has a folded position when a mixing shaft assembly is not rotating, and an open position when the mixing shaft and the folding blade assembly are rotated at a predetermined speed and the folding blade assembly is submerged in the radioactive substance. A method is provided for stirring a radioactive material in a vessel having a combination of liquid and solid substances, until that combination turns into a liquid slurry that can be pumped out of the vessel. The method includes providing an impeller mixer assembly having a folding blade assembly disposed at an end of a mixing shaft assembly, where the mixing shaft assembly is rotatable by a motor and the folding blade assembly includes an open position and a folded position. The end of the mixing shaft assembly having the folding blade assembly disposed at the end in its folded position is placed at a predetermined depth in radioactive material to be stirred. The impeller shaft assembly is rotated to a predetermined speed, which causes the folding blade assembly to enter the open position from its folded position, and mixes the combination of liquid and solids to a pumpable slurry for pumping out of the vessel.
