The UK Spherical Tokamak for Energy Production (STEP) program is currently progressing the conceptual engineering design of a Spherical Tokamak-based fusion reactor. The program includes a project concerned with design of the reactor breeding blanket. The objective of this work was to develop a low fidelity, integrated simulation approach to sup…

The development of discrete strain at the microstructural scale during the onset of plasticity is potentially linked to fatigue crack nucleation in engineering alloys. Hence, quantifying such discrete strain and its evolution is a pathway to understand the microstructural influence on fatigue crack nucleation and to develop crack initiation mode…

The development and distribution of microscopic shear strain have been investigated using high-resolution digital image correlation at the onset of plastic deformation in face-centred cubic CoCrFeNi high entropy al- loys with different grain sizes. Microscopic strain localisation increased with grain size as shown by the presence of planar slip …

In the hot metal forming processes, materials deform viscoplastically and the microstructure of materials changes dynamically, and constitutive equations used to characterize the material flow and microstructure evolution during the deformation can be complicated. Although different types of constitutive equations have been proposed by many researc…

The CHIMERA fusion technology facility, currently under construction at the UKAEA site in South Yorkshire, will enable testing of large in-vessel component modules under reactor-like conditions of combined in-vacuo thermal power density and magnetic field. With integral large superconducting magnet and PWR water loop, CHIMERA is also ideally pla…

Future fusion reactors using deuterium-tritium fuel will create high fluences of high-energy neutrons inside and around the reactor vessel. As well as causing material damage, fusion neutrons will activate materials, the decay of which leads to radiation fields in and around the reactor after shutdown. Gamma-ray emission from activated materials…

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…

A small, novel, integrated SHM system has been deployed during full-scale testing of a wing fatigue test and a fuselage pressurisation test. Complementary NDE measurement techniques were combined, with inputs from visible and infrared optical sensors, as well as resistance strain gauges. Sensor unitswere deployed at regions of interest and int…

The International Thermonuclear Experimental Reactor (ITER) is an international nuclear fusion research and engineering project with the aim to prove the feasibility of nuclear fusion as a large-scale carbon-free source of energy. The reactor vessel contains several diagnostic windows that provide a line of sight to the plasma. Design and qualif…
