Title:
TREATMENT METHOD FOR LONG-LIVED FISSION PRODUCT
Document Type and Number:
WIPO Patent Application WO/2017/109899
Kind Code:
A1
Abstract:
Provided is a treatment method for long-lived fission products which achieves increased efficiency in a process for conversion into stable nuclides by optimizing the composition of a target to which a charged particle beam is incident. This treatment method for long-lived fission products comprises: individually separating and extracting at least two types of elements (a first element 11 and a second element 12) selected from the group consisting of Cs, Zr, Se, Sn, and Pd from radioactive waste 10 (S21); acquiring range data when a charged particle beam 15 is incident to the target (S22); making a first bulk body 21 having a length in the range of 1.0 to 2.0 times the range data from the first element 11 (S23-S25); making a second bulk body to be disposed around the first bulk body from the second element 12 (S26, S27); and emitting a charged particle beam having an energy per nucleon in the range of 0.5 to 1.5 GeV (S28-S30).
