Patent number: 7526057Abstract: A decay heat removal system for a liquid metal reactor in which a decay heat exchanger (DHX) is installed concentrically with an intermediate heat exchanger (IHX) in the same cylinder which separates the DHX and IHX from the reactor pool fluid, and serves to remove the reactor core decay heat. The cylinder surrounds the IHX and DHX, and has an open top portion protruding out of the level of the fluid in a hot pool, a bottom portion connected to a cold pool and a guide pipe for allowing the passage of the fluid from the hot pool into the IHX. The decay heat removal system can remove decay heat immediately after occurrence of an accident, thereby improving the safety of a nuclear plant.Type: GrantFiled: October 29, 2007Date of Patent: April 28, 2009Assignees: Korea Atomic Energy Research Institute, Korea Hydro & Nuclear Power Co., Ltd.Inventors: Yoon Sub Sim, Seong O.

Patent number: 7522693Abstract: A direct pool cooling type passive safety grade decay heat removal method and system for removing core decay heat in a pool type liquid metal reactor when a normal heat removal system breaks down. In the liquid metal reactor comprising a reactor vessel, the interior of which is partitioned into a hot pool above a core and a cold pool around the core so that liquid level difference between the hot pool and the cold pool is maintained by a primary pumping head under normal steady-state conditions, is disposed at least one circular vertical tube in such a manner that the sodium in the circular vertical tube is maintained with the same liquid level as the liquid level of the sodium in the cold pool.Type: GrantFiled: October 1, 2003Date of Patent: April 21, 2009Assignees: Korea Atomic Energy Research Institute, Korea Hydro & Nuclear Power Co., Ltd.Inventors: Jae-Hyuk Eoh, Yoon-Sub Sim, Seong-O Kim, Dohee Hahn
