Model of the Toshiba ABWR, which became the first operational Generation III reactor in 1996.

A Generation III reactor is a development o Generation II nuclear reactor designs incorporating evolutionary improvements in design developed during the lifetime o the Generation II reactor designs. These include improved fuel technology, superior thermal efficiency, significantly enhanced safety systems (including passive nuclear safety), an standardized designs for reduced maintenance an capital costs. The first Generation III reactor tae begin operation was Kashiwazaki 6 (an advanced boiling watter reactor) in 1996.

Due tae the prolonged period o stagnation in the construction o new reactors an the continued (but declining) popularity o Generation II/II+ designs in new construction, relatively few third generation reactors have been built. Generation IV designs are still in development as o 2017, and are not expected tae start entering commercial operation until 2020–2030.
