Development of boron sheet and DT neutron irradiation experiments of multi-layered concrete structure with boron sheet

Abstract

a , The boron sheet was developed in order to reduce induced activity in concrete walls applied for neutron generation facilities, and it was applied to a new multi-layered concrete structure. DT neutron irradiation experiments were performed by using multi-layered concrete structure mockups with the boron sheet at FNS in JAEA. It is demonstrated that the multi-layered concrete structure with the boron sheet can effectively reduce the low energy neutrons, which leads to less induced activity in concrete walls.
