Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The stability of the KT-2 tokamak plasma has been analyzed in the framework of ideal and resistive linearized magnetohydrodynamics. KT-2 is the Korean tokamak project that involves a large-aspect-ratio divertor tokamak with an up-down symmetric plasma cross section. First, equilibria with monotonic q profiles are investigated. Starting from four ballooning stable reference equilibria with ever broader pressure profiles and with an aspect ratio of 5.6, an ellipticity of 1.8, a triangularity of 0.6, and a total plasma current of 500 kA, the effects on the shape of the poloidal plasma cross section (ellipticity and triangularity), the aspect ratio, and the total plasma current on the ballooning and ideal and resistive external kink instabilities are studied. Also, advanced tokamak scenarios have been investigated. A local profile optimization study is performed for a lower total current, i.e., Ip = 300 kA, and a magnetic field of 2 T. Next, the stability of the marginal ballooning stable equilibria with respect to so-called infernal modes is analyzed.
