Optimization of the Materials Composition in External Core Catchers for Nuclear Reactors

Atomic Energy, 2002
Existing schemes of core melt retention apparatus for water-cooled water-moderated nuclear reactors are analyzed. In-shaft variants of melt catchers at nuclear power plants with VVER-1000 reactors are proposed. It is shown that TiO2- and Nd2O3-based materials increase the operational reliability of the retention apparatus by modifying the processes ...

Development of an Enhanced Core Catcher for Improving In-Vessel Retention Margins

Nuclear Technology, 2005
In-vessel retention (IVR) of core melt that may relocate to the lower head of a reactor vessel is a key severe accident management strategy adopted by some operating nuclear power plants and proposed for several advanced light water reactors. A U.S.-Korean International Nuclear Energy Research Initiative project has been initiated to explore design ...

An Experimental Investigation on Molten Behaviors for a New Type Core Catcher

Volume 4: Thermal Hydraulics, 2013
A new core catcher concept was presented and experimentally investigated in the paper. The new core catcher composed by many vertical cells. Parallel steel plats protecting by the ceramic layer form a vertical channel which can accommodate core molten and cool it from both sides.
