The radiation effect is one of the critical aspects concerning fusion reactor development. The neutron and gamma radiation produced in the reactor vessels generates displacement defects and transmutations. Such micro-structural damage leads the materials to suffer degradation of its mechanical and physical properties. Embrittlement, swelling, stress corrosion cracking, hardening loss of optical transmission and of electrical isolation are some examples of the problems that radiation will cause on structural and functional materials used in [[ITER]] and [[DEMO]]. | The radiation effect is one of the critical aspects concerning fusion reactor development.

*Functional Materials: Candidate insulators to build the components of the diagnostics, heating systems and remote handling systems such as RF windows, mirrors, mineral insulating cables, fibre optics or optical windows. The range of enviromental conditions that these materials would withstand in the machine will be very broad depending on its function. | |||
*Structural Materials: Candidate steels to build the reactor vessel while resisting loads, high temperatures, high radiation fluxes and intense magnetic fields. | *Structural Materials: Candidate steels to build the reactor vessel while resisting loads, high temperatures, high radiation fluxes and intense magnetic fields. | ||
