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.

In the framework of the Paul Scherrer Institute (PSI) transient analysis project STARS, a boiling water reactor (BWR) stability analysis methodology based on the BWR system code RAMONA3 has been developed. The time series analysis based on parametric mixed autoregressive/moving average models is conducted by a MATLAB code package using the system identification and the signal-processing toolboxes of MATLAB. A short description of the PSI methodology is presented and two aspects of the stability analysis are discussed. First, the physical mechanism underlying the BWR power oscillations from the nonlinear feedback system point of view is discussed, and second, some experiences collected by the analysis of the regional stability phenomenon are presented.
