High power laser drivers and fast neutron sources towards green energy applications [Early Posting]
Accelerator Driven Systems (ADS) may offer a promising technology for energy production and transmutation of nuclear waste. Here we introduce the concept of utilizing high-intensity laser acceleration technology in realizing an ADS, with a focus on the use of thorium fuel in subcritical systems. We explore state-of-the-art laser-driven particle sources for neutron generation by nuclear fusion, spallation, or photonuclear reactions and the prospect of reaching the flux of $10^{15}$n/s required to drive a subcritical reactor. We review recent advances in high-power laser amplification and assess their technological readiness in view of integration in an ADS. Finally, we present a risk analysis of a laser-driven ADS in terms of laser and target development, radiation safety, and operational stability. Our conclusion highlights the potential of laser-driven ADSs as a transformative approach to nuclear fission energy. With continued R\&D, technological hurdles can be overcome to fully realize sustainable, green energy production that can meet global energy demands while addressing safety and environmental concerns.
