How to reduce overhead costs of fusion power plants?
VTT Technical Research Centre of Finland's research results indicate that joint planning of the reactor structure and remote maintenance system can significantly improve the utilisation rates of future fusion power plants. Designing a reactor with the simplest structure possible can reduce maintenance periods, as well as building expenses and overhead costs. Since 1995, VTT Technical Research Centre of Finland has participated in two international projects aimed at building a full-scale fusion reactor and commercialising fusion as an energy source.

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.
