We provide a brief summary and comments on how we utilized the Exascale Computing
Project (ECP) supercomputing resources for the development of the frontal research of nuclear fusion
reactor development. In turn, our demand and use helped stimulate the ECP hardware and software, …

We introduce a method of transmutation of spent radioactive nuclei in a liquid molten salt solution with fusion neutrons through a series of energy enhancements from accelerated deuterons via fusion to fission. This method is a part of the partitioning & transmutation (P&T) approach for the disposal of spent nuclear fuel where P&T enables the reduction of duration and volume of the spent nuclear fuel storage.

Norman Rostoker pioneered research of (1) plasma-driven accelerators and (2) beam-driven fusion reactors. The collective acceleration, coined by Veksler, advocates to drive above-ionization plasma waves by an electron beam to accelerate ions. The research on this, among others, by the Rostoker group incubated the idea that eventually led to the birth of the laser wakefield acceleration (LWFA), by which a large and robust accelerating collective fields may be generated in plasma in which plasma remains robust and undisrupted.
