Investigation of different methods to design the start-up core of the canadian SCWR

The Canadian concept of Super-Critical-Water reactor is a three-batch refuelling core with target exit burnup of 40 MWd/kg. It uses a mixture of plutonium and thorium oxides as fuel. The equilibrium cores as well as the refuelling scheme of this concept have been proposed by CNL (formerly AECL). The equilibrium core is the core which will be reached after refuelling the start-up core with the same fuel for a number of times in a three-batch …
