In materials proposed for Librti, it can be difficult to directly interpret the measured diffusivity of hydrogen isotopes because a majority of gas atoms may be trapped at defects such as impurities, dislocations, and grain boundaries. Unless taken at high temperature, so that the entropy dominates, or at high hydrogen concentrations where traps are filled, the measured diffusivity can be...
Liquid breeder-based blanket concepts have been proposed for fusion power plants around the globe. While there are ongoing projects addressing key challenges, such as flow under magnetic fields, safety, and heat transfer; the tritium breeding via neutron irradiation in flow is only scheduled to take place in over a decade from now [1] [2]. This has motivated the demonstration of flowing...
One of the priorities at Kyoto Fusioneering is breeding blanket design and build. To achieve this, we are actively developing different blanket designs in-house, working alongside UKAEA, LIBRTI, and private fusion partners. Our research and development efforts are shaped by uncertainties in both design and manufacturing processes. As a result, we established UNITY-1 -a non-nuclear integrated...
UKAEA is advancing the design and experimental readiness of scaled mock-ups for breeding blanket concepts through its contributions to the EUROfusion Work Package Breeder Blanket (WPBB). A major challenge in breeder blanket R&D is the absence of reactor-relevant experimental platforms capable of simultaneously reproducing the coupled thermal, hydraulic, magnetic and structural environments...
