RAPID

CRIEPI's sodium-cooled fast reactor of 10 MWt and 1 MWe for autonomous operation, which IAEA-TECDOC-1536 (2007) describes as factory fabricated and fuelled. The same document calls it a successor of CRIEPI's lunar-base RAPID-L concept; RAPID-L is a related but separate design and is not profiled here. This dated design profile does not establish current development, a deployment site or any regulatory permission.
