Industrial applications involving hazardous materials often require inspection within confined interiors, posing significant engineering challenges due to restricted access and complex geometries. Long-reach mechatronic systems are essential for these tasks, yet their kinematic design is typically ad hoc. This paper presents a task-driven design sy…

Multi-machine validation of full electromagnetic plasma initiation modelling with DYON was carried out by the joint modelling of the International Tokamak Physics Activity (ITPA) – Integrating Operating Scenario (IOS) group. The following devices were included in the experiment database: VEST (spherical torus, copper coils, Stainless steel wa…

The effect of different D2 fueling locations and divertor closure in the MAST-U is studied in detail with the SOLPS-ITER code to gain insights to detachment physics in H-mode plasma experiments in conventional divertor (CD) configuration. The SOLPS-ITER simulations for MAST-U H-mode plasma reveals that changing D2 fueling location significantly i…

Ensuring tritium fuel self-sufficiency while maintaining continuous and high specification fuel flow to the tokamak via a low tritium inventory and controllable fuel cycle is a significant challenge to the STEP plant design. Effective and high-quality fuelling and exhausting is required to sustain and control a stable plasma, whereas fuel suffic…

The pre-thermal quench (pre-TQ) dynamics of a pure deuterium (D2) shattered pellet injection (SPI) into a 3 MA/7MJ JET H-mode plasma is studied via 3D non-linear MHD modelling with the JOREK code. The interpretative modelling captures the overall evolution of the measured density and radiated power. The simulations also identify the importance of t…

We report on a new ground-level neutron monitor design for studying cosmic rays and fluxes of solar energetic particles at the Earth’s surface. The first-of-its-kind instrument, named the NM-2023 after the year it was standardised and following convention, will be installed at a United Kingdom Meteorological Office observatory (expected complet…

Disruption prediction and avoidance is a critical need for next-step tokamaks such as ITER. Disruption Event Characterization and Forecasting (DECAF) research fully automates analysis of tokamak data to determine chains of events that lead to disruptions and to forecast their evolution allowing sufficient time for mitigation or complete avoidance o…

In the quest of new materials that can withstand severe irradiation and mechanical extremes for advanced applications (e.g. fission & fusion reactors, space applications, etc.), design, prediction and control of advanced materials beyond current material designs become paramount. Here, through a combined experimental and simulation methodol…

Short-range order (SRO) in multicomponent concentrated alloys affects their mechanical response. Hence, is paramount to understand how composition modifies the chemical ordering in the system to design materials with optimal properties. We present here a methodology to predict the SRO and thermodynamic properties in chemically complex systems an…
