Abstract

Abstract

Based on the experience of Fukushima accident, this paper analyzed two typical core catcher designs, from EPR and WWER, and put forward three new conceptual schemes, i.e., the core grouping catcher, the Waffle core catcher, and the casting core catcher. The conclusion shows that the new schemes have obvious technical advantages.
- Core catcher,
- Severe accident,
- Core melt,
- Core Grouping Catcher（CGC）,
- Waffle Core Catcher（WCC）,
- Core Casting Catcher（CCC）
