Nuclear Safeguards instruments employ gamma ray, neutron and calorimetry measurement technologies to verify and quantify the presence of Special Nuclear Materials (SNM). Safeguards instruments either verify the radioactive fingerprint or signature of SNM and fission products (for example in spent nuclear fuel), or quantify SNM in bulk form (for example in unused nuclear fuel for verification purposes).
Safeguards instruments are sometimes used for nuclear materials assay for inventory and materials quantification purposes as well as for safeguards, for example in a nuclear fuel production plant.
The ANTECH Universal Neutron Counter N2000 has been designed to provide a state of the art neutron counting capability for nuclear safeguards, waste assay and accounting measurements for special nuclear materials.
The ANTECH Model N2442 Active Well Coincidence Counter (AWCC) is a transportable high efficiency neutron counter for the measurement of plutonium and uranium.
The ANTECH B2308 Combined Isotopic and Plutonium Scrap Multiplicity Counter for cans quickly and accurately determines the plutonium content of Special Nuclear Materials (SNM), scrap and residues.
The ANTECH N1081 De-Randomising Mixer Buffer provides useful test and diagnostic information for multi-counting chain neutron detectors by determining independent software readable neutron totals counting for each input counting chain and statistical data analysis for each counting channel.
ANTECH B2104 Series Fork Detectors are routinely used as inspection tools, for safeguards purposes, and to conduct non-destructive measurements to determine the radiation from reactor pond fuel rod assemblies while stored underwater.
ANTECH B2102 Series Fork Detectors are routinely used as inspection tools, for safeguards purposes, and to conduct non-destructive measurements to determine the radiation from reactor pond fuel rod assemblies while stored underwater.
The design of the demountable CA503-260 High Sensitivity In-Line (Glove Box) Calorimeter is based around a sample well that maintains glove box integrity.
The ANTECH Model N2018 High-Level Neutron Coincidence Counter is a medium efficiency passive neutron counter for measuring the spontaneous and induced fission from the even isotopes of plutonium bearing samples, including PuO2, mixed oxides, metal carbides, solution and scrap.
The ANTECH N2023-M Neutron Coincidence Collar (NCC), similar in specification to the ANTECH N2044 Neutron Coincidence Collar (NCC), is used by safeguards inspectors to verify the fissile material content of fresh BWR nuclear fuel assemblies.
The ANTECH N1003 Series Neutron Time Correlation Analyser (TCA) is a comprehensive multiplicity counter for the passive neutron analysis of plutonium.
N2108 Neutron Under Water Coincidence Counters (UWCCs) are routinely used as inspection tools, for safeguards purposes and to conduct non-destructive measurements to determine the radiation from reactor pond fuel rod assemblies whilst stored underwater.
N2106 Neutron Under Water Coincidence Counters are routinely used as inspection tools, for safeguards purposes and to conduct non-destructive measurements to determine the radiation from reactor pond fuel rod assemblies whilst stored underwater.
The ANTECH G3501 Plutonium Isotopic Ratio Spectrometer is a comprehensive measurement system for the determination of plutonium isotopic ratios.
The ANTECH Model N2098 Plutonium Scrap Multiplicity Counter is a high efficiency passive neutron counter for measuring the multiplicity of neutron emissions from the spontaneous fission and induced fission of plutonium bearing samples of scrap and residues.
The ANTECH CHF400 Series Precision Twin Cell Sample Calorimeters feature a thermostatically controlled calorimeter body that houses two identical cylindrical or rectangular cells, one “sample” and one “reference”. Both cells have the same construction and the same heat transfer properties. The CHF400 Series are available in a variety of volume sizes.
The CHF610-0020 Small Sample Pre-heater is a portable desktop instrument designed to preheat two small cylindrical canisters containing samples of a Plutonium Containing Material (PCM) to a temperature similar to that of the thermal block control temperature of a CHF610-0020 Transportable Small Sample Calorimeter.
