Accelerator Driven Systems and Their Applications 1.1 History of Accelerator Driven System Activities Since the early 1990’s, accelerator driven systems (ADS) – subcritical assemblies driven by high power proton accelerators through a spallation target which is neutronically coupled to the core – have been proposed for addressing certain missions in advanced nuclear fuel cycles. The Reactor Accelerator Coupling Experiment (RACE) Project, which is being conducted within the US. Department of Energy's Advanced Fuel Cycle Initiative (AFCI), is a series of accelerator-driven subcritical systems (ADSS) experiments.

The RACE Project, which is being conducted within the U.S. Department of Energy’s Advanced Fuel Cycle Initiative (AFCI), is a series of accelerator-driven subcritical systems experiments. The first of these experiments at the Idaho State University’s Idaho Accelerator Center (ISU-IAC) coupled a 30-MeV electron Linac with a sub-critical core. In Kyoto University Research Reactor Institute (KURRI), The FFAG accelerator complex for accelerator driven sub-critical reactor (ADSR) project has been already constructed and world first ADSR experiment has been done at May, 2009. In the main ring, proton beams of 11.5 MeV are injected and accelerated up to 100 MeV.

A subcritical reactor is a nuclear fission reactor concept that produces fission without achieving criticality.Instead of sustaining a chain reaction, a subcritical reactor uses additional neutrons from an outside source. There are two general classes of such devices. One uses neutrons provided by a nuclear fusion machine, a concept known as a fusion-fission hybrid. In future planned accelerator-driven subcritical systems, as well as in some recent related experiments, the neutron source to be used will be a pulsed accelerator.

 · As for breeders, the idea of accelerator driven subcritical systems also goes back to the 1950's, but no real need was seen . It was mainly in the 1990's with the decreasing public acceptance of nuclear energy in general, and of higher awareness of safety risks as well as unresolved issues with waste disposal that interest revived in a number of countries. Accelerator-driven subcritical reactors are hybrid systems that promise a range of important advantages over conventional reactors. These include increased safety (and therefore better public acceptance of nuclear power), less proliferation issues, greatly reduced radioactive waste production and the potential to use them for transmuting existing nuclear waste.

A redundant, low cost accelerator driven system for power generation or waste treatment. The system generates fission from fertile nuclear materials and includes multiple charged particle sources, nested redundancy of low energy accelerator sections for reliability, and multiple subcritical reactors. Merging and splitting devices based on radiofrequency transverse kickers enable the nested ... An accelerator-driven subcritical reactor is a nuclear reactor design formed by coupling a substantially subcritical nuclear reactor core with a high-energy proton accelerator. It could use thorium as a fuel, which is more abundant than uranium.. The neutrons needed for sustaining the fission process would be provided by a particle accelerator producing neutrons by spallation.

Accelerator reliability corresponding to a very low frequency of beam interrupts is an important new accelerator requirement for accelerator-driven subcritical reactor systems. In this paper we review typical accelerator-reliability requirements and discuss possible methods for meeting these goals with superconducting proton-linac technology. Electron Recirculating Linacs for Isotope Production. Applications of accelerator science to nuclear medicine... ERLs are increasingly the technology of choice for highly demanding applications. In energy recovery, more than 90% of the beam power is recycled and not deposited in a beam dump.

Accelerator Driven Subcritical Reactor (ADSR) Technology We believe an excellent approach for generating safe, clean, carbon-free power is the use of subcritical A conventional nuclear reactor operates within a few parts per million of criticality, where the number of neutrons created exactly equals the number used; below criticality the reactor turns off, and above criticality it explodes. for example, in Ukraine and South Korea, a linear electron accelerator is suggested for use in a subcritical facility. Unfortunately, our country not only does not ha ve its own program for dev ...
