Lawrence Livermore scientists have modeled actinide-based alloys, such as spent nuclear fuel, in an effort to predict the impact of evolving fuel chemistry on material performance.
This work, funded by a Laboratory Directed Research and Development Program on "Scientific Basis for Ultra-high Burn-up Nuclear Fuels," could have direct implications for the use of spent nuclear fuel as another source of energy.
Despite the limited availability of experimental thermodynamic data, this new approach can predict important features contained in phase diagrams, namely phases and their stability in composition-temperature domains and microstructures, and more importantly, guide and motivate further experiments for validating the methodology and the data for subsequent modeling of materials performance at higher scale, according to Patrice Turchi, lead author of a review paper appearing in the March issue of the Journal of the Minerals, Metals & Materials Society (JOM).

KSTAR aims for longer plasmas
At the Korea Institute of Fusion Energy (KFE), the KSTAR tokamak recommenced operations in December after a major upgrade to replace the device's carbon divertor with a tungsten divertor.
According to an article on the KFE website, the original carbon divertors could take a thermal load of 5MW/m², whereas the tungsten divertor can take 10MW/m². The upgrade is critical to the goal of sustaining a 100-million-degree plasma for 300 seconds by 2026. Data from the operational campaign will be directly relevant to ITER, which will operate a tungsten divertor under similar plasma conditions in terms of shape and structure.
This testing campaign will continue through February 2024. Read more about the plans in this article in English on the KFE website, or in Korean in the Chosun Biz.
