A közelmúltban befejezett háromdimenziós, kazettaszintű, csatolt neutronfizikai-termohidraulikai számítások során optimalizáltuk az üzemanyag dúsítását és a kiégő méreg koncentrációját. A végleges elrendezés konverziós tényezője egészen 40,0 MWnap/kg kiégettségi szintig meghaladja az önfenntartáshoz szükséges 1,0 határt.

The initial one-dimensional calculations were followed by two- and three-dimensional analyses, which resulted in the design of a two-pass assembly consisting of two regions with different fuel pin diameters and pitches. During the recently finished three-dimensional, assembly-wise, coupled neutronics - thermal hydraulics calculations we optimized the enrichment of the fuel pins and the burnable poison content. The final design is self-sustaining up to the burnup of 40.0 MWday/kg considering the fissile material. This means that after providing the initial fissile load, only the Thorium, which is 3-4 times more abundant on Earth than Uranium, has to be supplemented during the lifetime of the reactor. [G]
