Generation III reactor
A generation III reactor is a development of generation II nuclear reactor designs incorporating evolutionary improvements in design developed during the lifetime of the generation II reactor designs. These include improved fuel technology, superior thermal efficiency, passive nuclear safety systems and standardized design for reduced maintenance and capital costs. The first Generation III reactor to begin operation was Kashiwazaki (an ABWR) in 1996.
Due to the lack of reactor construction in the Western world, very few third generation reactors have been built in developed nations. In general, Generation IV designs are still in development, and might come online in the 2030s.〔(【引用サイトリンク】url=http://www.world-nuclear.org/info/Nuclear-Fuel-Cycle/Power-Reactors/Generation-IV-Nuclear-Reactors/ )〕

Improvements in reactor technology result in a longer operational life (60 years of operation, extendable to 120+ years of operation prior to complete overhaul and reactor pressure vessel replacement) compared with currently used generation II reactors (designed for 40 years of operation, extendable to 80+ years of operation prior to complete overhaul and RPV replacement). Furthermore, core damage frequencies for these reactors are lower than for Generation II reactors – 60 core damage events per 100 million reactor-years for the EPR; 3 core damage events per 100 million reactor-years for the ESBWR〔(Next-generation nuclear energy: The ESBWR )〕 significantly lower than the 1,000 core damage events per 100 million reactor-years for BWR/4 generation II reactors.〔
The third generation EPR reactor was designed to use uranium more efficiently than older Generation II reactors, using approximately 17% less uranium per unit of electricity generated than these older reactor technologies.〔(page 126. 3 Rs of Nuclear Power: Reading, Recycling, and Reprocessing Making a Better ...
