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 heating of plasmas by fast ions, with a focus on Neutral Beam Injection (NBI), is reviewed. First, the need of auxiliary heating and current drive systems in fusion machines is outlined. For the particular case of tokamaks, the limitations of ohmic heating are discussed. The different ways of generating fast particles in plasmas are presented. The principle of operation of neutral beam injectors is explained. Positive-ion (PNBI) and negativeion (NNBI) based concepts are discussed. Next, the physical processes by which the beam transfers energy to the plasma, namely ionisation and slowing-down are described. For both, an elementary theory is given, whereby simple approximations to the distribution functions of beam injected ions and of alpha particles in reactors are obtained. Applications of NBI to heating, current drive and rotation drive are reviewed and the prospects of NBI for ITER are commented.
