IFMIF-DONES will produce neutrons by irradiating liquid lithium with a 125 mA beam of 40 MeV deuterons. These deuterons will be accelerated by a linear accelerator, which is housed in the accelerator vault within the IFMIF-DONES main building. Neutronics modelling is crucial to determine radiation safety and component lifetimes, with accurate geo…

The 2023 JET deuterium–tritium (D–T) experimental campaign (DTE3) achieved record fusion energy output (69 MJ), providing a unique 14.1 MeV neutron environment for irradiation studies. A range of ITER material samples were exposed in a Long-Term Irradiation Station (LTIS) within the JET nuclear environment to neutron fluxes up to 2 × 10¹³ n/…

Knowledge of the mechanical properties of materials is required for the design and analysis of engineering products, however, the characterisation of heterogeneous properties using traditional techniques is limited by spatial resolution or insufficient reliability. This paper presents a novel methodology for the characterisation of hete…

Qualification of components operating in future fusion power plants will be heavily reliant on simulations of component behaviour. The lack of representative test environments for many aspects of the expected operating environment will necessitate full or partial virtual qualification of components. The cornerstone of virtual qualification is …

Constitutive behaviour of fusion-relevant steels in the post-necking regime is necessary for detailed design of future fusion device components. A Finite Element Model Updating (FEMU) procedure using Digital Image Correlation (DIC), a simulated DIC filter and novel constitutive law was developed. The effects of the DIC process and experimental nois…

The high source stability and brightness of field emission gun equipped scanning electron microscopes (SEM) makes them ideal for high-resolution digital image correlation (HRDIC). However, their high initial capital cost can be prohibitive for research organisations and groups. Conventional thermionic SEMs using either a tungsten hairpin or LaB

Scanning electron microscopy-based is now an established technique, providing full-field strain and displacement measurement at the microscale. Techniques for generating speckle patterns for sub-micron strain mapping are highly substrate dependent but typically rely on applying aggressive conditions which may alter the microstructure of interest…

In-vessel plasma facing components in fusion reactors such as ITER and DEMO experience high thermal loads and require active cooling, for which water is one possible coolant. The solution where plasma facing components utilise tungsten blocks as sacrificial armour has a joint internal structure of cooling tubes made from the copper base (~99% Cu…

This Review considers current Zr alloys and opportunities for advanced zirconium alloys to meet the demands of a structural material in fusion reactors. Zr based materials in the breeder blanket offer the potential to increase the tritium breeding ratio above that of Fe, Si and V based materials. Current commercial Zr alloys might be considered …

Shear strain profiles along slip bands in a modified Rolls-Royce nickel superalloy (RR1000) were analyzed for tensile sample deformed by 2%. The strain increased with distance away from a grain boundary (GB), with maximum shear strain towards the center of the grain, indicating that dislocation nucleation generally occurred in the grain interior. T…
