Use of deuteron-induced spallation reactions at intermediate energies has recently been proposed for transmutation of several long-lived fission products (LLFPs). In the design study of a transmutation system using a deuteron primary beam, accurate cross section data of deuteron-induced reactions on the LLFPs are indispensable. In the present study, production cross sections of residual nuclei in the deuteron-induced reactions on $$^{93}$$Zr and $$^{107}$$Pd at $$100-200$$ MeV/nucleon are analyzed using DEURACS, in which the breakup processes are explicitly taken into account. The calculated values reproduced the experimental data quantitatively well. From a component-by-component analysis, it was found that the components of nucleon absorption make the significant contributions to residual nuclei production. This result strongly indicates that consideration of the breakup processes is essentially important to predict production of residual nuclei in deuteron-induced reactions.

At present, a high power CW(Continuous Wave) electron linac accelerator is under development in PNC as a part of transmutation study by accelerators. Last year we performed nuclear and thermal calculation on a hybrid reactor system combining the electron linac and a subcritical core with TRU fuel as one of applied uses. It is well known that the hybrid reactor system can also use a proton accelerator instead of the electron one. The nuclear and thermal calculation was performed on the system using the proton accelerator in this year. Comparison of the extinguished quantity of TRU fuel was performed between calculation results of both systems. In the proton linac hybrid system, a proton beam accelerated from the linac is injected into a target located in the center of the subcritical core to produce neutrons by spallation reactions. The neutrons enter the surrounding subcritical core to extinguish the TRU. The result of calculation showed that the extinguished quantity of TRU was about 10 kg where the proton beam power of 100 MW injected into the subcritical core system of keff = 0.95 over 1 year. The extinguished quantity of TRU was about 100 times as large as that in the case studied last year on the electron linac hybrid system.

Theoretical model analysis of deuteron-induced spallation reactions on long-lived fission products

Nakayama, Shinsuke; Furutachi, Naoya; Iwamoto, Osamu; Watanabe, Yukinobu*

no journal, , 

In the ImPACT project, deuteron is a first candidate of incident beam for nuclear transmutation of long-lived fission products (LLFPs) and accurate deuteron nuclear data on LLFPs are strongly required. Thus, we have performed theoretical model analysis of deuteron-induced spallation reactions on LLFP with DEURACS, which is the computational code dedicated for deuteron-induced reactions. Through comparison with measured data and other calculation method, the applicability of DEURACS to spallation reactions and the role of breakup processes in the reactions will be discussed.
