Nuclear fusion could work — but only if we cough up some money
By Steven Cowley

Head of the EURATOM/CCFE Fusion Association
This December, world leaders will gather in Paris for the United Nations Climate Change Conference, where they will attempt — yet again — to hammer out a global agreement to reduce greenhouse-gas emissions. Despite the inevitable sense of déjà vu that will arise as negotiators struggle to reach a compromise, they must not give up. Whatever the political or economic considerations, the fact remains: if global temperatures rise more than 2˚C from pre-industrial levels, the consequences for the planet will be catastrophic.
But the challenge does not end with reducing emissions. Indeed, even if we make the transition to a cleaner world by 2050, we will need to determine how to meet a booming global population's insatiable appetite for energy in the longer term — an imperative that renewables alone cannot meet. That is why we need to invest now in other technologies that can complement renewables, and provide reliable electricity for many centuries to come. And one of the most promising options is nuclear fusion — the process that powers the sun and all stars.

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.
