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 chaotic phenomena of the low frequency magnetic fluctuations in the HANBIT device have been studied and measured by two magnetic probe arrays in the central cell. The HANA (HANBIT Nonlinear Analysis) code has been developed and used to analyze the magnetic fluctuations to determine whether or not it is chaotic. The autocorrelation function of the magnetic fluctuations is obtained at two different positions in the HANBIT device and was also used to determine chaotic transition. The influence of the magnetic field strength on the magnetic fluctuations has also been studied. When the magnetic field strength is over 0.229 T~ 0.233 T, wave bifurcation is observed and the Primary Lyapunov Exponent (PLE) value is increased. Hence, there is chaotic transition at a specific magnetic field strength in the HANBIT device.
