Small Innovative Reactor Designs—Useful Attributes and Status of Technology
Design and performance characteristics are examined of four representative Small Innovative Reactors (SIRs)—IRIS, PBMR, 4S and ENHS. It is shown that SIRs have a number of useful attributes, including the following: Reduced number of components and design simplicity; High degree of modularity, with complete modules fabrication and assembly in factory; Elimination of severe accidents by design leading to enhanced safety; Simplified operation and maintenance; Enhanced proliferation resistance; Close match between demand and supply of electricity; Short construction time; Long plant life; Investment protection; Cost effective approach to technology development. It is concluded that SIRs have significant differences in their design features and performance characteristics from large size reactors that justify taking a thorough examination of the desirability of their commercialization.
