Reduced activation ferritic-martensitic (RAFM) steels are a recent class of radiation-resistant steels designed for the structural components of power-producing fusion reactors. In this work an advanced (A)RAFM steel has been developed with superior radiation hardening resistance with respect to the EUROFER-97 upon which it was based. 4D-STEM (s…

This paper sets out what needs to be considered when considering a Funded Decommissioning Programme (FDP). In the UK a FDP is submitted to the secretary of state for approval as a requirement for a nuclear site licensee to install or operate a nuclear power station. The United Kingdom Atomic Energy Authority (UKAEA) Spherical Tokamak for Energy …

Future fusion power plants require structural materials that can withstand extreme operating conditions, including high coolant outlet temperatures, mechanical loading, and radiation damage. Reduced-activation ferritic martensitic (RAFM) steels are a primary candidate as a structural material for such applications. This study demonstrates the succe…

Two ferritic Oxide Dispersion Strengthened (ODS) steels Fe-12Cr-YWT and Fe-14Cr-YWT were irradiated in the High Flux Reactor (HFR) up to 3 dpa at a nominal temperature of 600°C. Tensile tests at room and elevated temperatures as well as microstructural investigations using transmission electron microscopy (TEM) and atom probe tomography (APT) were…

Predicting with high accuracy (low uncertainty) the performance of tritium breeding systems is a must for design engineering of future fusion devices. Current modelling relies on scant experimental data and is known to have uncertainties that if realised in a real system would p…

The SUSD3D computer code has been recently updated with new features including the extension of the nuclear data sensitivity and uncertainty (S/U) analysis to gammaray quantities such as gamma flux and heating. Gamma relevant nuclear data can be processed allowing S/U for coupled neutron/gamma problems. The code is available from the NEA data B…

EUROFER97 specimens Al-base coated using different processes, either chemical vapour deposition or electroplating, were oxidised at 980 °C for 60 minutes and 760 °C for 90 minutes to understand whether this 2-step oxidation process could provide a suitable oxide layer able to offer both corrosion protection and a tritium permeation barrier. The…

Neutron bombardment of high temperature superconducting (HTS) magnets may compromise the integrity of the magnetic confinement in future fusion reactors. The amount of damage produced by a single neutron can be predicted from the threshold displacement energies (TDE) of the constituent ions in the HTS materials, such as the Rare Earth Cuperates.…

Microstructural evolution–driven degradation governs material properties and is closely linked with defect behavior. Quantitatively characterizing defects and their evolution is essential for elucidating the underlying degradation mechanisms. To this end, the defects were introduced at room temperature using self-ion irradiation for damage lev…
