Membrane processes for Hydrogen separation and production
These membrane devices have been developed at ENEA Frascati laboratories for separation of hydrogen isotopes from tritiated water. Applied to the production of H2 from biomass, the dehydrogenation process on which these devices are based, allows the achievement of higher hydrogen and syngas yields than traditional reactors. Furthermore, these processes represent the only solution available for some kind of biomass (i.e. olive mill wastewater) that cannot be treated via the conventional biological processes.
Synthesis of nanometric MoNbW alloy using self-propagating high temperature synthesis
Considering applications for plasma facing materials (PFM) in tokamak, the French laboratory LSPM has developed a new methodology for nanometric refractory tungsten alloys manufacruting with high homogeneity in composition. The originality of the invention consists in providing to the nanopowders interesting properties’ such as a low brittle-to-ductile transition temperature in order to be machinable, and a good resistance to oxidation. The synthesis of nanometric tungsten alloy powder into submicron platelets offers an increase of ductility of up to 30% and make them suitable for fusion application. This methodology could be applied to other binary, ternary and quaternary alloys as well as High Entropy Alloys (HEA) and find therefore potential applications in non-fusion domains
Fast Gas Inlet Valve insensitive to Magnetic Fields
The object of the invention is to provide a fast gas inlet valve, primarily for emergency situations, fitted inside a magnetic field device, but not sensitive to the magnetic field. This device was originally developed for use within the nuclear fusion domain, but is also available for use in other domains with similar demanding environments.
Optimum grating parameters for a VUV (vacuum ultraviolet) spectrometer

The spectrometer geometry is also defined alongside the diffraction grating parameters. The invention from the research center Juelich (Germany) consists of a proprietary software code which uses various numerical methods to determine the optimal grating parameters, with the aim of producing such gratings for VUV spectrometers with a minimal line width for a predefined wavelength and at the same time achieving high spectrometer efficiencies.
Ultra Sniffer New leak detection method
The test sensitivity of classic sniffer test methods is limited by the helium concentration in the air, but by reducing the atmospheric helium concentration the test sensitivity can be significantly improved. The Ultra Sniffer Test gas (UST) method is simple - there is no evacuation of the test chamber, only a filling with helium free gas. The method has successfully been used for testing super conducting coils for Wendelstein 7‐X at the Max Planck Institute for Plasma Physics (IPP) in Greifswald. The technology is ready for use in the non‐fusion domain and is currently being commercialized by the inventor, Mr. Robert Brockmann.

The original use of these is in nuclear fusion reactors, for which they have been successfully tested and where such pipes would be exposed to extremely high temperature and pressure regimes, far exceeding the allowable regime of application of conventional (steel) pipes. The technology is ready for use in the non-­‐fusion domain and was patented by the inventors Jens Reiser, Bermhard Dafferner, Anfreas Hoffmann, Michael Rieth, Werner Schulmeyer and Anton Möslang.

Method for increasing the concentration of tritiated water
A leading European fusion laboratory has developed a method for increasing the concentration of tritiated waste water whilst reducing the volume. The process involves electrolysing the tritiated waste water and then humidifying the evolved gas to reintroduce the tritium into the waste water. This increases the concentration of the solution but reduces the volume. This could be applied in areas such as life sciences where tritiated water is used as a tracer.

EIRENE allows, in a flexible manner, a complex system of collisions (elastic collisions, ionization & recombination etc) to be defined for neutral particles via an input file.
Technology for producing and utilising a protective layer on martensitic steel
Martensitic steel is often used when high toughness Steel with high formability is required.

Nanofluids For Improved Heat Transfer
Research is underway into the use of nanofluids to improve the cooling of surfaces within fusion reactors that are exposed to extreme heat fluxes. Nanofluids are a mixture of liquids (typically water) with nanoparticles (<100nm) in a concentration that is usually less than 1% by volume. Nanoparticles being investigated are alumina, ceramics, and carbon nanotubes, as these are known to increase both the conductive and convective heat transfer coefficients by up to half an order of magnitude (5x), and the critical heat flux of current coolants by up to an order of magnitude (10x) for boiling heat transfer. Due to this, cooling systems that are based on nanofluids could deliver a step-­change in the power handling performance of heat exchangers and other components.
Neutron insensitive  silicon  ion  detectors  for  NPA  (Neutral  Particle  Analysis)
A leading European nuclear fusion institute has developed a thin silicon strip detector for 10‐1000 keV ions. The detector consists of an active silicon layer (5 µm thick for low‐energy ions, or 25 µm thick for detection of high‐energy ions) bonded to a silicon support (~300 µm thick). Unlike previous ion detectors, the thin silicon strip detector exhibits high background‐to‐signal separation and good radiation tolerance, so is effective in high gamma, neutron, or photon backgrounds. The detector works by converting ion energy directly to charge in the silicon.
Tungsten (Wf/W) Composites
Turbines with increased process temperatures in power plants, receivers in solar thermic power plants, melting crucibles in LED production, high power relays for energy saving light management and flywheels for energy storage and management – they all require the availability of high temperature materials that are resistant to cracking and show advanced strength. Tungsten composite materials tested at the Research Center Juelich offer a promising solution to these needs.

The Research Centre Juelich has gained substantial expertise in calibrating simulations on the basis of the Finite Elements Method that can be used to establish numerical material models to estimate component lifetime.
Functionally Graded Materials (FGMs)
A functionally graded transition between two materials with different material properties like thermal expansion increases the reliability of the connection between the two materials and provides the ability to control deformation, dynamic response, wear, corrosion, etc. FGMs can be used to connect many different materials such as metal/ceramic, alumina/zirconia, alumina/steel, tungsten‐carbide/steel, tungsten/copper, polymer/concrete, bones/metal, and aluminium/polyethylene.

The component is ideal for high heat flux applications such as energy generation or aerospace, as well as high neutron or plasma backgrounds. The component has been developed and successfully tested for use in the JET nuclear fusion reactor and so is highly resistant to thermal and neutron stress, and also thermal shock.

3-D Mesoscale Soft X-ray microtomography for low contrast biological or soft samples, with control of the X-ray
ENEA Laboratories in Frascati developed this mesoscale soft X-ray microtomography for reconstructing the 3-D structure of small, pretty transparent to X-rays objects, with moderate spatial resolution and very low contrast, like biological samples. Commercial microtomographs are not suitable for this application due to high energy working X-rays and not efficient detection. With this fusion-derived technology, the energy spectrum is tailored to maximize the contrast of the sample and the X-ray detector is optimized accordingly.
