ADS is the abbreviation for Accelerator Driven Sub-critical System, which works under the principle that spallation reaction is carried out between high-energy protons accelerated by accelerators and heavy target nuclei (for instance, Plumbum), during which dozens of neutrons can be generated by every proton, and these neutrons then serve as neutron sources to drive the sub-critical blanket system, so as to obtain energy through maintaining chain reactions of the sub-critical

2012-3-1 Accelerator driven systems (ADS), which operate in a subcritrical mode and stay sub-critical, regardless of the beam being on or off, can in principle address the safety issues associated with the criticality. Subcriticality can also improve the controllability of this nuclear system through a simple electronic control of the accelerator.

Reflexions - Accelerator-driven reactors
An ADS reactor (Accelerator Driven System), also known as a sub-critical system, bares little resemblance to current reactors. It is made up of two distinct parts: a particle accelerator and a reactor. The accelerator provides the reactor with neutrons, enabling the reaction to take place. This is why reactors are called sub-critical: the nuclear reaction cannot take place in a chain as in ...

2021-5-14 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 ...
