Nuclear energy innovation is vital for slowing climate change
In the last week, two news stories really captured the potential future for nuclear energy. In The New York Times, Matthew Wald reported from Georgia, where construction crews are slowly building the first two new nuclear reactors in thirty years.
And National Geographic's Will Ferguson reported from Tennessee that engineers and scientists are taking core samples and mapping regional geology as part of the early planning stages of building the first small modular nuclear reactor in the world.
Both projects face unique challenges, yet they both represent the beginning of two potential nuclear paths for reducing climate-warming carbon emissions in the United States (and potentially the world).

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.
