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.

A conceptual design for a radiation-hard “pointing” fast neutron ionization chamber that is capable of delivering a 1 MHz countrate of T(D,n) events at ITER is given. The detector will use a ∼1 cm3 volume of CO2 fill gas at 0.1 bar pressure in a ∼500 V/cm electric field. The pulse widths will be ∼10 ns, enabling it to operate in a flux of ∼6×1013 DT n/cm2/sec. A special collimator design is used, giving an estimated angular resolution of 4.5 degrees HWHM.
