Abstract

Spallation reactions for the long-lived fission products 137 Cs, 90 Sr and 107 Pd have been studied for the purpose of nuclear waste transmutation. The cross sections on the proton- and deuteron-induced spallation were obtained in inverse kinematics at the RIKEN Radioactive Isotope Beam Factory. Both the target and energy dependences of cross sections have been investigated systematically. and the cross-section differences between the proton and deuteron are found to be larger for lighter fragments. The experimental data are compared with the SPACS semi-empirical parameterization and the PHITS calculations including both the intra-nuclear cascade and evaporation processes.

Summary

Introduction

The role of nuclear power has been emphasized since the middle of the twentieth century. One of the major issues is the management on the radioactive waste in the spent nuclear fuel produced from the nuclear power plant. A research and development has been performed using the partitioning and transmutation technology for the reduction of the high-level radioactive waste (HLW) [1] and for the resource recycling from the spent nuclear fuel [2]. The spallation reactions have been performed for 137Cs, 90Sr and 107Pd in the aspect of nuclear waste transmutation for LLFP. The inverse reaction technique was adopted in the present work: the LLFP beams were used and proton/deuteron-induced reactions were conducted by using proton and deuteron targets. The present reaction study enables us to provide high-quality data for a possible solution to the LLFP transmutation
