LEMC™

The JCC-12 counter assays plutonium inventory samples by counting coincidence neutrons from the spontaneous fission of the even numbered isotopes of plutonium. 

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 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 is a high efficiency neutron coincidence counter designed for measuring the multiplicity of the neutron emission from both spontaneous fission and induced-fission reaction in plutonium and uranium.

The JCC-31 counter measures the ²⁴⁰Pu-effective mass in a sample by detecting coincidence neutrons from the spontaneous fission of plutonium. 

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.
