Title:
LONG-LIVED FISSION PRODUCT PROCESSING METHOD USING NEUTRONS
Document Type and Number:
WIPO Patent Application WO/2017/187730
Kind Code:
A1
Abstract:
The present invention provides a long-lived fission product processing method using neutrons that makes it possible to generate high intensity neutrons using only an accelerator without using a fast reactor or an accelerator-driven reactor and efficiently cause nuclear transmutation in long-lived fission products (LLFPs). In the present invention, high-energy first neutrons that form a beam in a single direction are generated through the breaking up of deuterons or other primary particles including neutrons as a result of the acceleration of the primary particles in an FFAG accelerator 10 under prescribed conditions such that the primary particles collide with a plate-like target 18, and low-energy, diffuse second neutrons are generated through the excitation of nuclei in the plate-like target. A first LLFP 20 is disposed in the travel direction of the first neutron beam and a second LLFP 24 is disposed in the vicinity of the plate-like target 18.
