SMRs not included in this report

This report does not address evolutionary SMRs. The descriptions of many of such designs, which are mostly water cooled reactors, can be found in [19, 20]. One could argue that some water cooled SMRs included in this report appear more like the evolutionary designs with innovative features but, as mentioned in Section 1.3, the decision to include them was made by their designers who also provided the justifications of why they rate their designs as innovative. 

An agreement to submit design descriptions for this report was not reached with the designers of BREST-300 lead cooled fast reactor from RDIPE (NIKIET) of the Russian Federation and the designers of CANDU X NC reactor from AECL of Canada (the latter is a Generation IV system with supercritical light water coolant). A description of the BREST-300 can be found in reference [21].
