Materials play a key role in the safe and economical operation of nuclear reactors. Materials used in reactors also have to meet stringent chemical specifications for efficient performance. Commercial scale realization of nuclear materials has been a challenge to the nuclear industry. The history of development of nuclear materials has fascinating and unique examples of theoretical prowess as well as innovative experi- mentation and success in nuclear material development is characterized by synergy between the domains of laboratory research and industry. This paper describes the development of some of the important nuclear materials (uranium, plutonium, zirconium, boron, sodium and graphite), providing a historical perspective. Keywords. Nuclear materials; uranium; plutonium; zirconium; boron; graphite; sodium; lanthanides; history; scale-up. 1. Introduction roles other than as fuels or control rod materials should also have very low neutron absorption so that Among the 118 elements known today, some elements they do not affect neutron economy. Fuel materials and their compounds play important roles in nuclear should also have very low concentrations of impu- energy, such as fuel, neutron absorber, moderator, rities that can cause parasitic neutron absorption structural material, coolant, etc.
