Understating natural intercellular circulation in the core during fault situations and transitional regimes results in suboptimal designs of pool reactors. For RBT reactors at the Research Institute of Nuclear Reactors, it is shown that instead of using structure elements specially intended for organizing a natural circulation loop the natural intercellular circulation can be fully taken into account. In addition, these structural elements themselves carry additional failure-associated risks. The results of a computational analysis of the development of pre-accident situations associated with the disruption of forced circulation of coolant through an RBT core and equipment failure are presented.
