Abstract

The IV generation nuclear plants are supposed to solve many problems: they will improve safety and efficiency, and will give for the fi rst time ever a convincing answer to the fuel cycle quest, being able to burn and destroy even the III generation nuclear wastes. But IV generation is not just a «small step» but a «giant leap» for nuclear technology. All of the six IV generation families require brand new materials, and very challenging solutions. Although no commercial plants are expected to be available before 2030, all the countries with a strong nuclear industry are trying to find their own way toward the future of nuclear energy. The race is open.
