<p>1,000,120. Making solutions of solids. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 27, 1962 [Dec. 13, 1961], No. 44615/61. Heading B1Q. A process for recovering fissile material from comminuted, used, nuclear fuels by leaching with nitric acid comprises feeding the fuel to the first mixing tank containing a leaching liquid, agitating by means of dip tubes 18 and 19, lifting a quantity of the mixture by means of low pressure line 16 to settler 12. Settled liquid is discharged back to the mixer through wide bore connection 13 and the solid sedimentary layer is discharged slowly to the following mixer through narrow bore connection 41 so progressing the solid through the mixer-settlers. The low pressure line which controls discharge of the cycle may be operated by electro-magnetic means. The shape and size of tanks is designed against criticality hazards.</p> |
