The Department of Energy (DOE) evaluated 19 reactor designs against 27 criteria and determined that the Integral Fast Reactor (IFR) is the best option for future energy needs. There are concerns regarding the maturity of IFR technology and its ability to achieve its theoretical potential. Some participants in the discussion suggest that the CANDU reactor also ranks highly but express a need for more information on the evaluation criteria. The Integrated/Integral Primary System Reactor (IPSR) is mentioned, highlighting that it has never been built or operated, raising questions about its feasibility. Overall, while the IFR is favored, there is a call for further development and operational experience before making definitive decisions.
