| One of the most relevant issues to be addressed in the near future for the design of future fusion reactors (DEMO, HiPER..) is the effect of light atoms, such as He, H, D, T and Li, in all the materials (first wall,structural and functional). These ions are produced by nuclear transmutation or introduced by interaction with the plasma, in considerable amounts and it is one of the significant differences between fusion technologies and other related areas like fission. This project aims to continue the scientific contribution to this topic, coordinating the efforts of a significant fraction of the Spanish community involved in fusion materials technology. Present work done by these groups has demonstrated their competence in this topic. The summary of the main project objectives can be described as follows: 1. To expand the demonstration that ion irradiations can be used for the simulation of the radiation damage in a future fusion reactor and contribute to the conceptual engineering design and prototyping of different facilities related to materials development for fusion applications (e.g. the facilities included in the National Centre for Fusion Technologies (TechnoFusión) or HiPER). A key aspect included is, in case of Inertial Fusion, the design and identification of a Virtual Reactor as basic systems where the problems to be studied are in the appropriate context. 2. To obtain detailed information about the behaviour of light ions (H isotopes and He) in candidate fusion materials, including ?in-beam? and ?post-irradiation? effects with different radiation sources. We attempt to produce and characterise an extended set of advanced materials: New types of ODS steels, ODS Cu, W alloys, C?based materials, Li ceramics and some nano-Fe materials (for basic studies). Their well controlled microstructures will allow us to know more about its role on the behaviour of light ions as well as to understand how defects accumulate in the process of damage with and without He. We also attempt, especially in the case of insulating materials, to separate the effect of the electronic interaction from that of the nuclear one, by using different irradiation sources and with special focus on the interaction of the above effects. 3. Carry out an analysis of the performances of the computer simulations related to the effect of radiation and light ions behaviour by using a multiscale approach, from quantum-mechanics firstprinciples, molecular dynamics, Monte-Carlo, Rate Theory methods to, in the last stage, dislocation dynamics, making a special effort to draw experiments suitable to the mentioned modelling techniques. This area is showing a great development and expansion, combining better hardware and clever algorithms. For this reason it is also important to make an effort on this last topic. | |
