Concept of accelerator-driven systems (ADS). Its basic concept was originally proposed by a Canadian scientist, W. B., Lewis in 1952 ( Lewis, 1952 ), and an integrated concept can be found in A. Harms' book in 1982 ( Harms and Heindler, 1982 ). If the above target and blanket are a molten salt of thorium (Th), then the above two-region ...

Nagoya University is currently developing a compact DC accelerator driven BNCT system using a sealed lithium (Li) target. The target receives a high heat load by a proton beam, and the heat then requires efficient removal. This study developed a high-efficiency heat removal technique that uses V-shaped staggered ribs on the heat removal side of ...

2.2 Beam Energy, Power and Time Structure Accelerator-driven systems require beam energy near 1 GeV to maximize the neutron yield per unit proton beam power. As the yield curve has a rather broad maximum, other technological arguments may favor higher or lower beam energy depending on specific design considerations.

We have explored the possibility of laser accelerator driven coherent X-rays using a free electron laser. The approach looks promising because of the replacement of the traditional magnet based undulator with a laser driven dielectric based undulator. Progress toward the accelerator and coherent X-ray source will be discussed.

Wiesner, FRANZ and Small-Scale Accelerator-Driven Neutron Sources May 5, 2015 Conclusion • Small-scale accelerator-driven neutron sources can provide intense neutron beams at modest sizes and costs. • The neutron energy range of keV to MeV is especially suited for nuclear astrophysics and BNCT. • Challenges are: compact, high-intensity

Applications of Accelerator Driven Systems • Accelerator Driven Systems may be employed to address several missions including:address several missions, including: Transmuting selected isotopes present in nuclear waste (e.g., actinides, fission products) to reduce the burden these isotopes place on geologic repositories.

Neutron imaging has been recognized to be very useful to investigate inside of materials and products that cannot be seen by X-ray. New imaging methods using the pulsed structure of neutron sources based on accelerators has been developed also at compact accelerator-driven neutron sources and opened new application fields in neutron imaging.

A novel high-intensity beam monitor, using resonant gas-filled RF cavities, is being developed for extremely high-radiation environments. These are needed in facilities produce intense proton, neutron and neutrino beams for particle physics research, material science and accelerator-driven subcritical reactors.

Intensity ranges shown in Fig. 1 are required for the accelerator-driven neutron source. Higher intensity is better for all experiments since usually statistics and resolution become better or the amount of the sample required for measurement becomes small with increasing the intensity.

Because accelerator driven systems do not require fuels containing uranium or thorium, they are more efficient at destroying MA waste – up to seven times more efficient according to one study [6] – than critical reactors, based on grams of minor actinides fissioned per MW-hr of energy generated.

For example, one version of a Plutonium burning system requires an 800-MeV, 80-mA, proton accelerator running at duty factor. This accelerator requires approximately 110-MW of continuous RF power if one assumes only 10% reserve power for control of the accelerator fields.

The concept of an accelerator-driven subcritical reactor (ADSR) is based on the idea of coupling a fission reactor to a particle accelerator. Currently, the production of energy from nuclear power plants requires the use of critical reactors, in which the number of neutrons released by fission is just enough to sustain a controlled chain reaction.

An accelerator-driven subcritical reactor is a nuclear reactor design formed by coupling a substantially subcritical nuclear reactor core with a high-energy proton or electron 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 or ...
