47. Consequences of neutron irradiation of fusion plasma-facing materials and components

Prof. Christian Linsmeier (Forschungszentrum Jülich GmbH, Institute of Fusion Energy and Nuclear Waste Management – Plasma Physics, Jülich, Germany)

Invited Talk

Plasma-facing materials and components are the interface between the fusion plasma and the reactor’s material structure. In a burning fusion reactor, they are directly exposed to the neutrons from the D-T fusion reaction. Neutron-exposed materials undergo changes in their composition due to transmutation reactions, both towards light elements (H, He) and heavy isotopes. In addition,...

Talk

The employment of neutron radiography and tomography allow non-destructive visualization of hydrogen distribution in cladding tubes due to the strong neutron attenuation by hydrogen compared to the weak attenuation by zirconium. The excellent spatial resolution of neutron radiography and sensitivity enable a precise characterization of hydride morphology and hydrogen gradients in 2D and 3D....

17. Time-of-Flight Neutron Imaging for Material Identification and Characterization

Alexander Wolfertz (TUM FRM2)

Talk

Neutron imaging is a non-destructive, spatially resolved technique that is frequently employed to analyze samples for which x-rays have a low penetration capability or provide poor contrast. While in many cases even complex structures can be mapped using a broad neutron energy spectrum without energy-resolution (white beam imaging), some sample properties only provide sufficient contrast at...
