JCC-61™/JCC-62™
The JCC-61 and JCC-62 counters quantitatively measure fast breeder fuel sub-assemblies, individual fuel pins, or a group of fuel pins. The Features
JCC-51™
The JCC-51 counter is used to make active neutron measurements on items such as bulk UO2 samples, high-enrichment uranium metals, UAl alloy scraps, LWR fuel pellets and 238UTh fuel materials. The Features
JCC-31™
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. The Features
JCC-13™/JCC-14™
The JCC-13 and JCC-14 counters provide a flatter axial response and higher efficiency than the JCC-12™ unit. The cylindrical-shaped sample holder accommodates various samples including liquids, powders and pellets. The Features
JCC-12™
The JCC-12 counter is a field-proven, IAEA-authorized neutron coincidence counter designed for accurate, non-destructive assay of plutonium inventory samples. Developed under U.S. Department of Energy programs and validated by international safeguards authorities, the JCC-12 delivers reliable performance in a compact, transportable form factor — ideal for routine inspections and facility-level nuclear material verification. The Features
WM3500
The WM3500 is a high-performance, modular neutron detection system designed for accurate, non-destructive plutonium quantification in a wide range of sample sizes. Its curved slab architecture and high-efficiency 3He detectors enable both precise quantitative analysis and rapid go/ no-go screening, making it ideal for nuclear safeguards, waste assay and material accountability applications. The Features
WM3210
The Model WM3210 Passive/Active Neutron (PAN) Shuffler system uses a high speed transfer mechanism to shuffle a 252Cf interrogation source between a source shield assembly and the counting chamber, giving it the ability to be used for both passive and active neutron coincidence counting of fissionable materials. The Features
JCC-41™
The JCC-41 is a high-performance, well-type neutron coincidence counter designed for in-plant measurement of large plutonium samples. With Monte Carlo-optimized geometry, enhanced shielding and a large sample cavity, it delivers superior efficiency, uniform response, and precision — making it ideal for both high-mass and lowlevel plutonium assay in operational environments. The Features
WM3100
Combining a detection efficiency of over 30% with increased shielding to reduce backgrounds, the HENC system is designed to assay 208 liter (55 gallon) drums to detection levels on the order of 1.6 mg of 240Pu-effective in a 1000 second count time. The Features
NDA 2000™
The NDA 2000 software is designed to be a complete acquisition, analysis and archival package for use with all Mirion neutron counters and gamma-ray systems. The Features
