Experiments and finite element modelling have been used to explore a method for miniaturising fibre push-out testing to the scale of thin ion irradiated layers. Correlation of interfacial surface area to debond stress has been identified for short fibres, and is related to a size effect following a Weibull distribution. Weibull analysis may be us…

This paper reports the use of combined microscopy and small angle neutron scattering (SANS) to probe into the compositional and size evolution of the primary carbides and nanoparticles (defined by a size threshold of 100 nm) in an additively manufactured high-alloy steel before and after heat treatment. The primary carbides show a marginal chang…

New Technologies such as High Temperature Superconducting magnets and advanced computing in Fusion Reactors, Advanced Generation IV Reactor Technologies or Off-Site Modular Construction are exciting developments in low carbon energy. Modular Reactors enable “factory shop build and transport to site” according to the International Atomic Ener…

Body-centered cubic metals and alloys irradiated by energetic particles form highly mobile prismatic dislocation loops with a/2 {111} -type Burgers vectors. We show how to simulate thermal diffusion of prismatic loops using a discrete dislocation dynamics approach that explicitly includes the stochastic forces associated with ambient thermal fluctu…

A low temperature jet impingement based heat sink module has been developed for potential application in a near-term fusion power plant divertor. The design is composed of a number of hexagonal CuCrZrsheets bonded together in a stack to form a laminate structure. This method allows the production ofcomplex flow paths using relatively simple manufac…
