LIQUID STOCK FOR DROPPING, METHOD FOR PREPARING LIQUID STOCK FOR DROPPING, METHOD FOR PREPARING URANYL NITRATE SOLUTION, AND METHOD FOR PREPARING POLYVINYL ALCOHOL SOLUTION

摘要

The object of the present invention is to provide a feedstock liquid, from which fuel kernels with good quality can be produced, and a method of preparing the feedstock liquid. The present invention provides a feedstock liquid with a viscosity from 4.0 x 10 -2 to 6.5 x 10 -2 Pa·s at 15°C, for the production of ammonium diuranate particles. The present invention also provides a method of preparing a feedstock liquid used for the production of ammonium diuranate particles, which includes mixing a uranyl nitrate solution and tetrahydrofurfuryl alcohol to produce a uranyl nitrate mixture, dissolving polyvinyl alcohol in water to produce an aqueous polyvinyl alcohol solution, mixing the aqueous polyvinyl alcohol solution with tetrahydrofurfuryl alcohol to produce a polyvinyl alcohol solution, and mixing the uranyl nitrate mixture with the polyvinyl alcohol solution.
