JCC-51™

The LEMC large epi-thermal multiplicity counter is a high-efficiency, fast-response neutron multiplicity counter engineered for high-precision, non-destructive assay of plutonium and uranium materials, including impure and mixed-oxide (MOX) scrap. With advanced epi-thermal neutron detection and high-efficiency design, the LEMC counter delivers fast, accurate results — ideal for nuclear safeguards, waste management and inventory control.

Delivering trusted precision for nuclear safeguards, the JCC-61 and JCC-62 counters deliver high-accuracy, non-destructive plutonium measurement for fast breeder reactor fuel. Backed by Los Alamos National Laboratory innovation and IAEA authorization, these counters are engineered for field reliability, ease of use and regulatory compliance – making them essential tools for nuclear facilities under international requirements.

The Model JCC-71 Neutron Coincidence Collar is a passive/active neutron counter for the measurement of the ²³⁵U content per unit length in fresh PWR, BWR and CANDU fuel assemblies.

The PSMC Plutonium Scrap Multiplicity Counter combines high-efficiency neutron detection with intelligent multiplicity analysis to deliver fast, non-destructive measurements of plutonium and uranium — even in complex scrap and MOX materials — giving nuclear operators the precision and confidence they need for safeguards and inventory control.

The JCC-31 is a versatile, high-efficiency neutron coincidence counter designed to measure the effective mass of ²⁴⁰Pu in a wide range of plutonium-bearing materials. Developed through a technology transfer from Los Alamos National Laboratory, the JCC-31 combines precision, portability and safety features to support safeguards, waste management and nuclear material accountability.
