In order to take advantage of nuclear fusion, in addition to solar and star, to meet the energy needs of the earth, one step more has been taken to investigate the safety and reliability of the parts used in fusion energy devices by two researchers using two imagery imagery.

Swansea University scientists, the Fusion Energy Culham Center, ITER France and the Max-Planck Institute of Plasma Physics connect Germany with images of x-rays and neutrons to demonstrate the robustness of the pieces.

Both methods comprise valuable data for the development of components.

The sun is a glowing example of fusion of action. At the ends of pressure and temperature, in the middle of the sun's atoms, trying to mix together, they release a large amount of energy. In the decades, scientists took advantage of a safe, carbon-free and virtually unlimited energy source.

One of the main obstacles that the different temperatures that the components of the fusion devices have to undergo will have to undergo temperatures: 10 times at the temperature of the central heat of the sun.

One of the main focuses on fusion, magnetic combinations, reactors with the highest temperature on the ground and potentially in the universe: plasmas of 150 million C and kripopump, which is a few meters below -269 ° C.

It is critical that the researchers can test, not destructive, the robustness of engineering components that must work in this extreme environment.

The research group is geared towards a critical component called monoblock, which carries a coolant. This was first imaged through computerized tomography for tungsten monoblock design. They used the imaging tool ISIS Neutron and Muon Source neutrons.

Dr. Triestino Minniti, Director of Science and Technology Facilities, said:

"Each technique has its own advantages and disadvantages. The advantage of the image of neutrons with ultraviolet rays is that neutrons are significantly tungsten.

Thus, the image of samples with higher tungsten volume is feasible. Neutral tomography also forces us to investigate a completely devastating monobloque, eliminating the need to produce "regions of interest".

Dr Swansea University School of Engineering Llion Evans said:

"This work is a conceptual proof and that these tomography methods can create valuable data. In the future, these complementary techniques can be used for research into the development of the fusion component design or manufacturing quality guarantee."

The next step is to make 3D images created by dynamic techniques in simulation engineering with micro-spatial resolution. This technique, known as the finite elemental imaginary method (IBFEM), can be individually assessed by the small deviation from the performance of each piece and the design caused by the manufacturing process.

Research was published Fusion Engineering and Design.
