|Abstract:||Neutron Resonance Transmission Analysis (NRTA) is a Non-Destructive Analysis (NDA) technique that relies on the use of resonance structures in neutron induced reaction cross sections. An active NDA system based on NRTA is under development to identify and quantify Special Nuclear Materials (SNM) and Minor Actinides (MA) in a wide variety of nuclear materials, including next generation fuel and highly radioactive materials. The development profits from the knowledge and experience gained in the development of Neutron Resonance Densitometry (NRD) as a NDA method to characterize particle-like debris from melted fuel. In this presentation, the basic principle of NRTA is explained. Results obtained for a NRD prototype device are used to estimate typical counting statistics uncertainties. In addition, the impact of the width of the pulsed charged particle beam on the experimental transmission is verified by measurements at the KURRI time-of-flight facility.|
