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.

Influence of the magnetic field, which is produced around the JT-60 tokamak, on the performance of the neutral beam injector was experimentally studied using the stray field simulating coils installed around the prototype injector unit. Temperature distributions on the ion dump shifted vertically and the peak values changed in the presence of the field, as expected from the calculation of ion orbits. The shift length and the peak values remained within the permissible level, however, because of the operation of two cancellation coils, one of which was set around the reflecting magnet and another around the neutralizer magnetic shield. The neutral power injected into the beam target decreased by 4 to 5 % during application of the stray field due to the reionization loss of neutral particles. Under operating conditions, the heat load on each component was below the design value and all the components worked without any problems in the presence of stray magnetic field.
