Abstract To evaluate the feasibility of development of nuclear transmutation
technology and an advanced nuclear system, precise nuclear data of neutron capture
cross sections for long-lived fission products (LLFPs) and minor actinides (MAs)
are indispensable. In this chapter, we present our research activities for the measurements of neutron capture cross sections for LLFPs and MAs.
