The fusion-born alpha-particle heating in magnetically confined fusion machines is a high priority subject for study. The self-heating of thermonuclear fusion plasma by alpha-particles was observed in recent deuterium-tritium (D-T) experiments on the Joint European Torus (JET). This observation was possible by conducting so-called “af…

"Effect of inclusion of pitch-angle dependence on a simplified model of RF deposition in tokamak plasma"

• JET contributors

Using the PION ICRH modelling code on JET tokamak pulses, the effect of including pitch angle dependence within the RF diffusion operator is investigated. This is found to be of greatest importance to the particle distribution function in cases of higher harmonic heating and lower heating ion mass, resulting in faster drop-off of the distribution

The Safety and Environmental Work Package (WPSAE) has the scope to progress the safety studies for the future EU DEMO reactor, in the frame of the Eurofusion programme. A Generic Site Safety Report (GSSR) has been designed to include all the steps necessary to cover the safety issues of the nuclear fusion plant, from the definition of principles an…

"The Licensing of Nuclear Fusion Power Plants - a Proportionate Approach"

• L.G. Williams
• N. Taylor
• M. Lukacs

The commercial exploitation of nuclear fusion energy for electricity production is now nearer than previously imagined. Several organisations are developing fusion reactors with the aim of demonstrating electricity production in the 2030s. These timescales suggest that conceptual designs are being worked on now and the detailed design, construct…

Pre-conceptual design studies for a European Demonstration Fusion Power Plant (DEMO) have been in progress since 2014.  At this stage, while a range of design options are being considered, it is essential that assessments are carried out of the safety and environmental impact of these options.  This is not only to ensure that the DEMO plant is op…
