Plentiful Energy is a technical-and-historical account of the Integral Fast Reactor (IFR), a nuclear power system developed at Argonne National Laboratory between 1984 and 1994. Charles Till and Yoon Il Chang—two leaders of the program—reconstruct how decades of earlier fast reactor work (EBR-I and EBR-II) converged into a “whole system” concept: a sodium-cooled fast reactor, metal fuel, pyroprocessing-based recycling, and durable waste forms, all designed to work together on a single site.
The book aims at non-specialists who can tolerate light technical detail. It walks through the engineering choices (fuel, coolant, reactor configuration), the safety logic behind “inherent/passive safety,” the electrorefining chemistry that enables recycling without producing pure plutonium, and the implications for waste longevity and energy security. It also documents the political rise and abrupt cancellation of the IFR program in 1994, arguing that a near-complete technology was halted primarily by policy, not technical failure.
