Synthetic evaluation method for fast reactor cycle with AHP and utility theory, etc.

Shiotani, Hiroki

In the Feasibility Study Phase 2 final evaluation, 20 candidate Fast Reactor (FR) cycle concepts were evaluated from six viewpoints including safety, economics, environmental burden reduction, efficient utilization of natural uranium resources, and nuclear non-proliferation in the multidimensional evaluation. Analytical Hierarcy Process (AHP) was used in the weighting of the viewpoints and the framework of Multi Attribute Utility Theory (MAUA) was also used in the evaluation. The FR cycle with soudium-cooled fast reactor was considered as the most promising concepts from the synthetic evaluation result for various reactor systems.
