Abstract
A simulated solution of 30 %TBP OK extracted uranium, zirconium, HDBP, and then stripped with NaOH and Na 2CO 3, is used in the selection experiments of filter elements and study on its filtering performance. An enlarge experiment has been executed and its scale is 1/7 to 1/9 of pilot experiment. The results show the micro cilia filter element of glass fire and absorbent cottonare the first choise in depth filtering. The former was used in the plant and being well against irradiation. The filter element of absorbent cotton should be tested in the real plant for against irradiation. The filter element of sinter stainless steel is the candidate one in surface filtering.rethefirstchoiseinde
