A full scale thermal neutron coincidence counter (High Level Neutron Counter – Boron: HLNB) based on ³He alternative detection technology was designed and built at LANL and field tested at Plutonium Conversion Development Facility (PCDF) of Japan Atomic Energy Agency (JAEA) during FY15. HLNB is based on boron-lined proportional plates that replace the traditional ³He proportional tubes and was designed as a direct alternative to ³He-based High Level Neutron Coincidence Counter (HLNC-II). During the JAEA field trial the HLNB demonstrated comparable performance to HLNC-II, which represents a key development in the area of ³He alternative technologies and provides a complete demonstration of the technology for nuclear safeguards applications including high mass MOX samples.
