But Warsaw gave an initial signoff on a fleet of 24 SMRs, Abu Dhabi's nuclear champion looked to the domestic deployment of SMRs, advanced reactors and microreactors, Seoul touted its brand new "i-SMR", and a Canadian province even launched a plan to remit carbon charges from power utilities into an SMR fund. Any number of further memorandums of understanding (MOU), from Mongolia to Belgium, made clear that there is enormous energy behind SMR deployment.
