Reactor Materials - Modern Status

Abstract

This paper presents short description of modern status of reactor materials for nuclear. The fast growing energy demand and concerns about climate changes require nuclear energy to play a role among other energy sources to satisfy future energy needs of mankind. Exactly core materials behaviour provides safe and economy exploitation of nuclear power plants. Metals and alloys used in nuclear service serve in very challenging environments involving high temperatures and stresses, as well as exposure to high irradiation doses. Problems of radiation resistance of materials for exploitation reactors and reactors of next generation are described.
