The WM3100 HENC™ High Efficiency Neutron Counter delivers highly accurate, nondestructive assay of 55-gallon waste drums — combining >30% neutron detection efficiency, automated operation and advanced correction techniques to ensure reliable plutonium quantification even in complex matrices.

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 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 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.
