Neutron Resonance Transmission Analysis (NRTA) is a promising nondestructive analysis (NDA) method capable of measuring various nuclear materials (NMs) with high accuracy. NRTA thus has been garnering attention as a method to reduce material unaccounted for (MUF) in material accountancy and enhance detection capabilities for concealed NMs at ports and airports. However, the large sizes of existing NRTA systems make them impractical for installation in nuclear facilities with limited spaces. To overcome this situation, we develop a table-top NRTA system using a Cf neutron source. In this presentation we will outline our advancements in NRTA development to date and introduce the structure of the table-top NRTA system currently in progress. This research was implemented under the subsidy for nuclear security promotion of MEXT.
