The TechnoFusión project, currently in a preparatory study phase, involves the construction of a Singular Scientific-Technical Facility (National Centre for Fusion Technologies - TechnoFusión) in the Region of Madrid, Spain, creating the required infrastructure for the development of the technologies required for future commercial fusion reactors, and assuring participation by Spanish research groups and companies.

It is not yet decided what materials will be used to construct future fusion reactors, partly because it has not yet been possible to reproduce the extreme conditions to which such materials will be subjected. Therefore, it is of utmost importance to dispose of installations capable of manufacturing new materials on a semi-industrial scale and fabricating prototypes. Top priority materials include metals such as reinforced low activation ODS type steels ([[:Wikipedia:Oxide dispersion strengthened alloy|Oxide Dispersion Strengthened steels]]) and tungsten alloys. To manufacture such materials, equipment is required that currently is scarce or inexistent in Spain, such as a Vacuum Induction Furnace (VIM), a Hot Isostatic Pressing Furnace (HIP), a Furnace for Sintering assisted by a Pulsed Plasma Current (SPS), or a Vacuum Plasma Projection System (VPS).

Inside a fusion reactor, some materials will not be subjected only to radiation, but also to enormous heat loads in the case of plasma disruptions. In view of this, both: i) stationary conditions due to the intrinsic reactor properties: high density, low temperature and high power and ii) violent transient events (known as [[Edge Localized Modes|ELMs]] in plasma physics literature) must be reproduced. Therefore, it is essential to dispose of a device (which it will be called “plasma gun”) to study plasma-material interactions simultaneously in steady state and transient regimes, thereby allowing an analysis of the modification of the materials and their properties in fusion reactors.

Therefore, it is essential to dispose of a device (a so-called “plasma gun”) to study plasma-material interactions simultaneously in steady state and transient regimes, thereby allowing an analysis of the modification of the materials and their properties in fusion reactors.  
The mentioned plasma gun would consist of two main elements: i) a linear plasma device capable of generating hydrogen plasmas with steady state particle fluxes of up to 1024 m-2s-1 (i.e., of the order of the expected ITER fluxes) and impact energies in the range of 1-10 eV, and ii) a device of the quasi-stationary plasma accelerators (QSPA) type, providing pulses lasting 0.1-1.0 ms and energy fluxes in the 0.1-20 MJm-2 range, in a longitudinal magnetic field of the order of 1 T or greater.

These devices are connected by a common vacuum chamber, allowing the exchange of samples, and their simultaneous or consecutive exposure to the steady state and transient plasma flows under controlled conditions. Both devices will operate with hydrogen, deuterium, helium, and argon.

In order to study conditions that cannot be reached in experiment and to accelerate the development of novel systems for a future commercial fusion power plant, TechnoFusión will stimulate an ambitious programme of computer simulations, combining the existing experience in the fusion field with resources from the National Supercomputation Network. Its goals include the implementation of the global simulation of a commercial fusion reactor, the interpretation of results, the validation of numerical tools, and the development of new tools. Another indispensable goal is the creation of a data acquisition system and the visualisation of results.
