Previous studies of the European Demonstration fusion reactor concept (DEMO) have shown that the expected amounts of radioactive waste at end of life (EOL) are of the order of 104 tonnes. These studies also suggested that comparable amounts of waste will be classified as low level waste (LLW) and intermediate level waste (ILW) 100 yea…

This paper describes a case study in seeking to encourage widespread adoption of Systems Engineering at the UK Atomic Energy Authority. Until recently, the quest for fusion energy has primarily been in the scientific research domain, but with a shift in focus to delivering commercially viable fusion power plants, there is a clear need for SE to …

Nuclear power, conceived during the second world war as a mass destruction technology, has now become the primer technology aiming at low-carbon emission source of energy. Furthermore, the joining of the once divided West and East has led to a worldwide research ground that involves not only physics or chemistry but many other engineering fields…

With MAST-U’s first plasma achieved in November 2020 and one of the key aims of the first experimental programme being to study exhaust physics, there is strong motivation to develop a new probe designed specifically for studying edge turbulence effects in the exhaust region of MAST-U. To create a new versatile probe, the design will be valida…

Ion cyclotron emission (ICE) comprises strongly suprathermal emission, which has spectral peaks at multiple ion cyclotron harmonics. ICE is driven by the magnetoacoustic cyclotron instability, resulting from an inversion in the velocity-space distribution of the minority energetic ions. Recent experimental studies on DIII-D (K E Thome et al

Disruptions pose a serious challenge for future tokamak power plants; at the large stored thermal and magnetic energies of ITER and DEMO plasmas, the heat loads and electromagnetic forces during disruptions must be mitigated. With this objective, JET experiments employing impurity shattered pellet injection (SPI) have recently been undertaken. W…

An important part of the ITER Research Plan [1] is the Pre-Fusion Power Operation (PFPO) phase, which includes demonstration of H-mode plasma operation and the commissioning of ELM control systems. However, since hydrogen or helium are the main ion species in PFPO plasmas, the L–H power threshold PL–H is expected to be cons…

Many of the essential data analysis procedures for a tokamak experiment rely on the knowledge of the magnetic field structure obtained from MHD force balance. On JET, the code that is responsible for computing the magnetic equilibrium is called EFIT++. Interpretation of JET data has been challenging due to inconsistencies between diagnostic meas…

The high heat fluxes to the divertor during edge localised mode (ELM) instabilities have to be reduced for a sustainable future tokamak reactor. A solution to reduce the heat fluxes could be the Super-X divertor, this divertor configuration will be tested on MAST-U. ELM simulations for MAST-U Super-X tokamak plasmas have been obtained, using JOR…
