Patent number: 9916907Abstract: A combination of a top nozzle and a guide thimble of a nuclear fuel assembly and, more particularly, a structure for joining an inner-extension tube, the top nozzle and the guide thimble. When an inner-extension tube head, which is provided as a means for facilitating removal of the top nozzle of the nuclear fuel assembly from the guide thimble, is removed from an inner-extension tube body to separate the top nozzle from the nuclear fuel assembly, the inner-extension tube body is prevented from undesirably rotating, so that the guide thimble and the inner-extension tube body can maintain the joined state.Type: GrantFiled: October 14, 2016Date of Patent: March 13, 2018Assignee: KEPCO NUCLEAR FUEL CO., LTD.Inventors: Nam-Gyu Park, Kyu-Tae Kim, Jung-Min Suh, Shin-Ho Lee, Kyong-Bo Eom, Joon-Kyoo Park, Jin-Sun Kim, Gyu-Cheol Shin, Seong-Ki Lee, Il-Kyu Kim, Ki-Sung Choi, Kyeong-Lak Jeon

Patent number: 9431134Abstract: Disclosed herein is a joint structure between a top nozzle and a guide thimble. The joint structure includes an outer guide post, an inner-extension tube head, an inner-extension tube body, a wedge and the guide thimble. The outer guide post is provided with an external thread formed on a lower end thereof. The inner-extension tube head includes an annular retaining part formed on an upper end thereof. An internal thread is formed on a medial portion of the inner-extension tube head. An external thread is formed on each of upper and lower ends of the inner-extension tube body. A stop protrusion is provided under a lower end of the wedge. The wedge is welded to the inner-extension tube body after the top nozzle has been joined with the guide thimble. A stop protrusion receiving depression is formed in the guide thimble.Type: GrantFiled: August 14, 2012Date of Patent: August 30, 2016Assignee: KEPCO NUCLEAR FUEL CO., LTD.Inventors: Nam-Gyu Park, Kyu-Tae Kim, Jung-Min Suh, Shin-Ho Lee, Kyong-Bo Eom, Joon-Kyoo Park, Jin-Sun Kim, Gyu-Cheol Shin, Seong-Ki Lee, Il-Kyu Kim, Ki-Sung Choi, Kyeong-Lak Jeon
