METHOD OF RECOVERING URANIUM THROUGH COMPLEXATION OF POLYVINYLALCOHOL-URANIUM AND MANUFACTURING THE NUCLEAR FUEL PELLET BY ADDING POLYVINYLALCOHOL-URANIUM COMPLEX

摘要

The present invention relates to a method of collecting uranium powders and uranium scraps generated during a pellet manufacturing process, uranium ions residing in waste water, and a nuclear fuel pellet manufactured by using the method. According to the present invention, an efficient method for handling the uranium scraps generated during a nuclear fuel manufacturing process and the uranium residing in the waste water is provided. The nuclear fuel pellet, which is manufactured by the uranium handling process and contains polyvinylalcohol-uranium complex serving to act both as a pore forming agent and a U_3O_8 powder, is provided. Therefore, the uranium scraps generated during a nuclear fuel manufacturing process and the uranium residing in the waste water are processed efficiently, the uranium is effectively utilized, and an economic feasibility of the nuclear fuel is improved.
