Abstract
Generation IV (GenIV) nuclear power concepts have become an active research topic all over the world during the last five to ten years.
There are six concepts accepted for the GenIV international forum (GIF) with the common aim to promote both efficiency and safety of reactor technology. Moreover, the issues of uranium sources and the use of closed fuel cycles are included in the discussion and concepts.
Thus, the new concepts will offer attractive features but at the same time bring new and demanding challenges for the materials technology due to increased operating temperatures and irradiation doses as well as more aggressive coolants and/or longer life time expectations than those for plant operated today.
In the present paper, an overview of the material issues is given with special emphasis on one of the concepts, namely the supercritical light water reactor.
