Passive and active neutron measurement systems are available to accommodate common container and inventory sample sizes.
Provides measurement and/or confirmation of uranium enrichment using the enrichment meter technique.
The JSR-15 Handheld Multiplicity Register (HHMR) is a handheld shift register/multiplicity circuit intended for neutron counting applications.
The LEMC Large Epi-Thermal Multiplicity Counter is a high performance 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-12 counter assays plutonium inventory samples by counting coincidence neutrons from the spontaneous fission of the even numbered isotopes of plutonium.
The WCAS system provides simultaneous passive neutron coincidence and high resolution gamma isotopic analysis allowing rapid characterization of plutonium wastes.
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 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 WM3400 counter measures the plutonium content in 200 L (55 gal) drums by detecting coincidence neutrons from the spontaneous fission of the even numbered isotopes of plutonium.
The JCC-61 and JCC-62 counters quantitatively measure fast breeder fuel sub-assemblies, individual fuel pins, or a group of fuel pins.
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 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 curved slab neutron coincidence slab counter measures the plutonium content of the sample by detecting coincidence neutrons from the spontaneous fission of the even numbered isotopes of plutonium.
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-41 counter is designed for in-plant measurements of large plutonium samples (up to several kg Pu), but can be used for plutonium waste samples with milligram quantities of plutonium.
The JSR-14 Neutron Analysis Shift Register is a portable, fully computer controlled neutron analyzer that provides both neutron coincidence and multiplicity capability that is selectable through use of the provided setup software.
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.
