Alternative Divertor Configurations (ADCs) often make use of high total flux expansion (fR) and connection length (L∥) to improve the access to and the controllability of detachment, a regime vitally important for reactor-class tokamaks such as the Spherical Tokamak for Energy Production (STEP). However, there has been little effort in assessi…

Pyvale is an open-source software package that aims to become an all-in-one tool for sensor simulation, sensor uncertainty quantification, sensor placement optimization, and calibration/validation. Central to this is support for image-based sensors, with a dedicated Digital Image Correlation (DIC) module designed for both standalone use and integra…

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…

In the paper we present validated integrated modelling of JET experiments in which fusion performance is driven by reactions between fast ions and intrinsically present metal wall impurities. A steady-state L-mode plasma with dominant proton-beryllium fusion and neutron yields of up to ≈ 6 x 1013 s-1 is developed in He and D…

The European Spallation Source Active Cells Facility is a unique facility for processing highly radioactive waste produced by the experiment. Due to the levels of radiation produced by the waste components combined with the scale of operations, the facility was designed to be operated without windows, using robotic manipulation systems and camer…

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 …

This paper presents simulations of alpha-particle transport in ITER driven by static 3D magnetic field perturbations in the high-performance 15 MA Q = 10 baseline scenario, specifically resonant magnetic perturbations (RMPs) arising from edge-localized mode (ELM) control coils, combined with toroidal field ripple (TFR) and effects from ferromagn…

Reduced activation ferritic-martensitic (RAFM) steels are a recent class of radiation-resistant steels designed for the structural components of power-producing fusion reactors. In this work an advanced (A)RAFM steel has been developed with superior radiation hardening resistance with respect to the EUROFER-97 upon which it was based. 4D-STEM (s…

The first results of studies of high-power (≥ 3 MW) H-mode discharges in double-null X-point-target (XPT) divertor configuration on MAST-U are presented. By combining the large strike point radius of the Super- X divertor with an additional X-point in the baffled outer divertor chambers, further exhaust benefits in strongly detached conditions…
