The Case for Near-term Commercial Demonstration of the Integral Fast Reactor
(To download this white paper as a PDF, click here,)
Demonstrating a credible and acceptable way to safely recycle used nuclear fuel will clear a socially acceptable pathway for nuclear fission to be a major low-carbon energy source for this century. We advocate a hastened timetable for commercial demonstration of Generation IV nuclear technology, via construction of a prototype reactor (the PRISM design, based on the Integral Fast Reactor project) and a 100t/year pyroprocessing facility to convert and recycle fuel.
We propose an accelerated timeframe for realizing the sustainable nuclear energy goals of the Generation IV reactor systems. A whole–system evaluation by an international group of nuclear and energy experts, assembled by The Science Council for Global Initiatives, reached a consensus on the synergistic design choices: (a) a well-proven pool-type sodium-cooled fast reactor; (b) metal fuel, and (c) recycling using pyroprocessing, enabling the transmutation of actinides.
