Characterisation Services

Cavendish Nuclear has over 50 years of experience in providing radiological measurements, support and advice to nuclear facilities around the world. This work is carried out by our team of highly qualified and experienced physicists, technicians and engineers. Cavendish Nuclear provides a range of radiological and radiometric measurements to ensure the efficiency and safety of nuclear material processing facilities.

A key component of our service has been the provision of in-situ non-destructive assay measurements in support of operating plants, decommissioning projects and waste management facilities.  The range of services we provide includes:

Data Sheets

Cavendish Nuclear’s RadScan® 4pi Gamma Imaging system is used to provide an enhanced radiological characterisation of gamma hotspots in a variety of environments including building surfaces, cells, gloveboxes and process vessels.

PHUMS is a lightweight, compact and portable assay system with the flexibility to measure the Plutonium / fissile / nuclear material content of a wide range of objects including process cells, facilities, gloveboxes, pipes and drums to inform Post Operation Clean Out strategies.

Cavendish Nuclear’s Liquor Level Monitor uses the neutron backscatter technique in a hand held instrument which measures the level and interfaces of liquids such as water and oils in vessels, tanks and pipes.

Cavendish Nuclear has a proven ability to generate 3D gamma dose rate maps in high
dose rate nuclear environments to support operations and decommissioning planning,
minimising operator dose uptake. This technique involves combining radiometric
measurements with the plant geometry in a computer model.

We have over 40 years of experience providing radiological and radiometric
measurements, support and advice to nuclear facilities. A key component of our service
has been the provision of on-site non-destructive assay measurements in support of
operating plant, decommissioning projects and waste storage/treatment facilities.

DISPIM® is a modular, mobile, re-configurable neutron assay system with the flexibility to measure the plutonium / fissile / nuclear material content of a wide range of object sizes and shapes including, but not limited to, gloveboxes, crates and drums, determining both the mass and distribution of plutonium within the object.

The safe decommissioning of redundant nuclear reprocessing cells containing contaminated items can be a technically challenging and time-consuming task. Cavendish Nuclear and its partners have developed a system which combines technologies in spatial and radiometric scanning, remote deployment and virtual reality (VR) control to create a complete toolkit for safe and efficient decommissioning of these cells.
