Due to the extreme operating temperatures in nuclear fusion reactors, current materials exhibit a substantial mismatch in mechanical and thermal properties between the tungsten plasma-facing material and the CuCrZr heat sink cooling system. Therefore, a thermal barrier interlayer is required to guarantee continuous operation. In this work, (CrVW…

Refractory High-Entropy Alloys (RHEAs) are promising candidates for structural materials in nuclear fusion reactors, where W-based alloys are currently leading. Fusion materials must withstand extreme conditions, including i) severe radiation damage from energetic neutrons, ii) embrittlement due to H and He ion implantati…

Metal melting has been widely viewed as the most promising method for detritiating metallic waste, with its potential to release more tritium than other thermal methods. Furthermore, the homogenization of the metal post melting is expected to distribute tritium throughout the ingot, reduc…

The ability to capture the isotope mass scaling of core confinement seen in experiment is validated with JETTO-TGLF for low power JET-ILW discharges across H, D and T. The cases analysed include Ohmic discharges spanning the linear and saturated Ohmic confinement regimes as well as a trio of L-modes. The TGLF saturation rules SAT1-SAT3 are seen to …

Abstract: This study focuses on improving the control system of vehicle suspension, which is critical for optimizing driving dynamics and enhancing passenger comfort. Traditional passive suspension systems are limited in their ability to effectively mitigate road-induced vibrations, often resulting in compromised ride quality and vehicle handli…

In its lifetime of around 40 years of scientific operations, JET has performed three full-scale DT experimental campaigns: one in 1997 (DTE1) and two more in a relatively quick succession in 2021 (DTE2) and 2023 (DTE3). One of the goals of these campaigns, apart from studying variety of physics effect relevant to DT plasmas, was demonstration of fu…

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 first measurements of energetic particle-driven ion cyclotron emission (ICE) in the Mega-Amp Spherical Tokamak Upgrade (MAST-U) have been obtained by adding a high sampling rate (250MHz) capability to one coil of the existing OMAHA array, oriented to measure fluctuations in the toroidal magnetic field component. All these measurements were carr…

JET is the only tokamak capable of Deuterium-Tritium (D-T) operations. The first D-T operations were in the 1990s and again in 2004. In 2020/2021 JET operated a much larger D-T campaign aimed at sustained high fusion power requiring a much higher tritium throughput. This paper presents an overview of the recent Tritium Injections into the JET To…

Several fusion plasma devices with magnetic confinement aimed at the burning deuterium-tritium plasma experiments are under construction or at a design stage that includes diagnostics design. Gamma-ray measurements, as well as neutron diagnostics are among the very restricted set of plasma diagnostics that can be acceptable in future D-T
