Patent number: 8969646Abstract: A method of preparing a simple ceramic ingot of a spent filter having radioactive cesium trapped therein, and a ceramic ingot of a spent filter having improved properties such as leach resistance, thermal stability, and cesium content are provided. The method includes grinding and mixing a spent filter having cesium trapped therein, adding a solidifying agent, and sintering the spent filter. The method of preparing a ceramic ingot of a spent filter can be useful in preparing the ceramic ingot of the spent filter from only the spent filter by means of simple grinding and sintering, and in preparing the ceramic ingot of the spent filter by adding a small amount of a solidifying agent. The ceramic ingot of the spent filter has a high density and improved thermal stability, and shows improved leach resistance since a leach rate of a radioactive material is remarkably low. Therefore, the spent filter having radioactive cesium trapped therein can be effectively used to prepare a stable ceramic ingot.Type: GrantFiled: September 5, 2013Date of Patent: March 3, 2015Assignees: Korea Atomic Energy Research Institute, Korea Hydro & Nuclear Power Co., Ltd.Inventors: Jin-Myeong Shin, Jae Hwan Yang, Jang Jin Park, Youngja Kim, Geun-Il Park

Patent number: 8298503Abstract: A filter type trapping agent for volatile cesium compound and trapping method for volatile cesium compound thereof are provided. More particularly, a filter type trapping agent for volatile cesium compound including silica 40-65% by weight of silica, 15-30% by weight of alumina, 5-15% by weight of iron oxide, 1-15% by weight of molybdenum oxide, 1-10% by weight of chromium oxide, and 1-10% by weight of vanadium oxide and trapping method for volatile cesium compound thereof are provided. Through a filter type trapping agent for volatile cesium compound and a trapping method, only cesium can be selectively separated among the nuclear fission gases. Accordingly, by disposing only the filter where cesium is trapped, the efficiency of an off-gas process improves, expense for disposing filter wastes decreases, and a cesium isotope of the waste filter can be recycled. Therefore, many forms of cesium compound gas are made insoluble efficiently.Type: GrantFiled: August 30, 2010Date of Patent: October 30, 2012Assignees: Korea Atomic Energy Research Institute, Korea Hydro & Nuclear Power Co., Ltd.Inventors: Jin Myeong Shin, Jang Jin Park, Jae Won Lee, Jeong Won Lee

Patent number: 5433864Abstract: The invention discloses a method for treating a heavy metal containing waste water by using acorns. Acorns and nuts of other trees belonging to the Eagaceae group are dried at the room temperature and under the sun beams. Then acornic acid is extracted from the dried acorns. Then the acornic acid is filtered until it becomes colorless. A heavy metal containing waste water (low concentration and high concentration) is maintained at pH=8-11.5 by adding NH.sub.4 OH, Ca(OH).sub.2 and NAOH. Then the acornic acid is added into the waste water, and then, Ca.sup.++ ions singly or together with other divalent cations are added by 50 ppm. Then this solution is agitated for several minutes, and then, the heavy metals are precipitated, or the solution is filtered, thereby treating the heavy metal containing waste water.Type: GrantFiled: May 11, 1994Date of Patent: July 18, 1995Assignee: Korea Atomic Energy Research InstituteInventors: Myung-Whan Yun, Jang-Jin Park, Yun-Whan Lee, In-Soon Chang, Jae-In Sin
