The nuclear transmutation of long-lived fission products (LLFPs), which are produced in nuclear reactors, is one of the candidate techniques for the reduction and/or reuse of LLFPs. To design optimum pathways of the transmutation process, several nuclear reactions have been studied using LLFPs as secondary beams. The studies indicate that proton- and/or deuteron-induced spallation reactions at intermediate energy (100 - 200 MeV/u) are effective for the LLFP transmutation.
For a systematic study, we performed an experiment for the proton- and deuteron-induced reactions on 107Pd and 93Zr at 20 − 30 MeV/u. In this energy region, the fusion evaporation process is dominant. Thus, the reaction-mechanism dependence can be studied by comparison with the high-energy spallation data. The experiment was performed at RIKEN RIBF. The degraded RI beams at 20 - 30 MeV/u were produced by a newly developed beam line, OEDO. To induce the reactions, the high-pressure cooled gas targets (H2 and D2) were used. Reaction residues were analyzed by the SHARAQ spectrometer.
In this talk, we will present the details of the experiments and the obtained results.
