The Standard Segmented Gamma Scanner (SGS system) is designed to perform accurate
quantitative assays on gamma emitting nuclides found in fission products,
activation products, and Transuranic (TRU) waste.
Cronos®-1 Gamma Object/Tool Monitor is an extremely sensitive instrument used to
detect radioactivity on small articles such as notebooks, keys, tools, hard
hats, and other miscellaneous objects.
Cronos®-4 and Cronos®-11 Gamma Object/Tool Monitors are extremely sensitive
instruments used to detect gamma radiation in/on articles such as waste bags,
tools, briefcases, hard hats, and other miscellaneous objects.
This ISOCS (In Situ Object Counting System) Shield has been designed as the
optimum in convenience and functionality for in situ gamma spectroscopy with a
germanium detector.
The Integrated Crate Interrogation System is comprised of a Box Segmented Gamma
Scanner (BSGS) providing high resolution gamma spectroscopy, and a Box Neutron
Assay System (BNAS) providing passive neutron counting capability, each mounted
in its own separate ISO container.
The IWAS Integrated Waste Assay System is a multi-modality system which provides
a combination of active and passive neutron interrogation as well as
quantitative gamma analysis.
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 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 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 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 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.
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 ‘Remotely Monitored Sealing Array’ or RMSA system is a versatile, low-power
active sealing solution that can support multiple sealing and containment
verification disciplines.
Hybrid K-Edge Densitometry (HKED software) is a highly accurate non-destructive
analysis technique used to determine the uranium and plutonium concentrations in
dissolver and product solutions as an alternative to chemical (destructive)
analysis.
FRAM (Fixed-Energy, Response Function Analysis with Multiple Efficiency) software
is a code used primarily to determine the isotopic composition of plutonium in
special nuclear materials.
Multi-Group Analysis (MGA software) was designed to improve the accuracy of these
measurements over traditional methods. In addition to the primary application of
measuring Pu isotopics,
Uranium measurements are typically difficult because of varying container shapes,
container wall thicknesses, uranium chemical forms and other complications.
Multi-Group Analysis for Uranium
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 ISOCS (In Situ Object Counting System) Calibration Software brings a new
level of capabilities to gamma sample assay by eliminating the need for
traditional calibration sources during the efficiency calibration process.
