Keywords:FBR, re-critilicality, core geometry, core disruptive accident, convex shaped core

In core disruptive accident (CDA) of sodium-cooled fast reactors (SFRs), fuel and steel can melt to form a molten pool. The objective of the present work is to investigate design measures for core of SFR to prevent recriticality.
