The 2023 JET deuterium–tritium (D–T) experimental campaign (DTE3) achieved record fusion energy output (69 MJ), providing a unique 14.1 MeV neutron environment for irradiation studies. A range of ITER material samples were exposed in a Long-Term Irradiation Station (LTIS) within the JET nuclear environment to neutron fluxes up to 2 × 10¹³ n/…

Fluid activation is of critical importance to fusion power plant design, as it can impact dose rates to maintenance personnel, heating in sensitive components, and radionuclide inventories with implications for accident scenarios and waste. The levels of fluid activation in a system are dependent on the neutron flux spectrum and the exposure time o…

The generation and accumulation of dust in future nuclear fusion reactors pose challenges related to safety, waste management and environmental impact. Dust, flakes and droplets form because of plasma-facing component erosion, with highly tritiated and activated materials accumulating in-vessel and during decommissioning activities. Estimations for…

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…

Determination of the absolute neutron rate production in any fusion device and in particular for ITER and future power plants is essential for their operation and for the optimization of the fusion power. A common calibration approach is to use a well characterized neutron sources placed inside the vacuum vessel combined with Monte Carlo simula…

Global research programmes seeking to achieve a commercially viable model of a fusion power plant are being accelerated at an unprecedented rate. One critical element to the design and licensing is an accurate understanding of the radiation environment throughout the plant lifetime and subsequent decommissioning phase. The radiation field which res…

JET is an experimental fusion reactor consisting of magnetically confined, high temperature plasma insidea large ultra-high vacuum chamber. The inside of the chamber is protected from the hot plasma withtiles made from beryllium, tungsten, carbon composites and other materials bolted to the vessel wall.The study was carried out in response to a JET…
