"Magic-RR Project overview: Objectives, methodology and expected results"
Most research reactors (RRs) in Europe are over 60 years old, and there are only limited efforts underway (e.g., PALLAS and JHR projects) to partially replace this aging infrastructure. Continued safe operation (CSO) of these reactors is crucial to sustaining the EU’s leadership in nuclear materials development and qualification for advanced r…

"Characterisation of Irradiation Damage in Fe-3Cr and Fe-5Cr: A Study on the Effects of Chromium Content and Temperature"
Fe–Cr binary alloys serve as simplified model systems to study irradiation damage relevant to fusion structural materials. Here, Fe-3%Cr and Fe-5%Cr samples were irradiated with 4 MeV Fe ions with a dose rate of 4 × 10⁻⁵ dpa/s across a linear thermal gradient (120°C–480°C) in a single experiment, enabling direct comparison of temperatu…

"EUROfusion contributions to ITER nuclear operation"
ITER is of key importance in the European fusion roadmap as it aims to prove the scientific and technological feasibility of fusion as a future energy source. The EUROfusion consortium of labs is contributing to the preparation of ITER scientific exploitation and operation and aspires to exploit ITER outcomes in view of DEMO. The paper provides …

"Radiation-induced precipitation of chromium in Fe-Cr alloys containing C and N impurities: First-principles modelling and experimental observations"
Using exchange Monte Carlo (MC) simulations based on an ab initio-parameterized Cluster Expansion (CE) model, we explore the phase stability of low-Cr Fe-Cr alloys as a function of vacancy (Vac), carbon, and nitrogen interstitial impurity content. To parameterise the CE model, we perform density functional theory calculations for more than 1600 …

"PosgenPy: An Automated and Reproducible Approach to Assessing the Validity of Cluster Search Parameters in Atom Probe Tomography Datasets"
One of the main capabilities of Atom Probe Tomography (APT) is the ability to not only identify but characterise early stages of precipitation at scales that are not achievable by other techniques. The most popular method, based on the Density-Based Spatial Clustering of Applications with Noise (DBSCAN), is used extensively in many branches of r…

"Understanding the residual stress distribution in laser welded Eurofer97 steel by neutron diffraction and Bragg edge imaging"
Eurofer97 steel is a primary structural material for the plasma facing-components of future fusion reactors. Laser welding is a promising technique that can overcome the challenges of remote handling and maintenance. However, the interaction of the induced residual stress distribution with the heterogeneous microstructure may degrade the mechanical…

"A novel pathway for multi-scale high-resolution time-resolved residual stress evaluation of laser-welded Eurofer97 Pending Yiqiang Wang"
The plasma-facing components of future fusion reactors, where the Eurofer97 is the primary structural material, will be assembled by laser-welding techniques. The heterogeneous residual stress induced by welding can interact with the microstructure, resulting in a degradation of mechanical properties and a reduction in joint lifetime. Here, a Xe

"Atom probe tomography for isotopic analysis: development of the 34S/32S system in sulfides"
Using a combination of simulated data and pyrite isotopic reference materials, we have refined a methodology to obtain quantitative δ34S measurements from atom probe tomography (APT) datasets. This study builds on previous attempts to characterize relative 34S/32S ratios in gold containing pyrite using APT. We have also improved our understand…
