URANUS-40

Historical 2011 Seoul National University small modular lead-bismuth cooled fast-reactor concept: 40 MWe nominal and 100 MWth, with gross/net electrical basis unspecified. The original abstract describes a pool-type reactor suitable for a single unit or a cluster. This dated configuration is distinct from the later UNIST MicroURANUS 20 MWe/60 MWth profile. No current development, named deployment or licence is inferred.

Catalogue identity snapshot: 2011 (dated technical description; not confirmation of current development or availability). Later technical descriptions, where recorded, are dated separately below. Source review does not establish current availability or a deployment.
