N-Visage™ Gamma Imager

Our customer – Nuclear engineers especially those working in decommissioning and contaminated environments.

The customers problem – Making detailed remote contamination and waste assessments in 3D to enable accurate project planning when access is severely limited and environments are contaminated.

Our view of the problem

We realised that this was fundamentally a 3D imaging problem – the ideal solution would be a technology that could produce a quantified 3D map of the radiation sources in a cell. We therefore looked to medical imaging for inspiration, where technologies such as PET and SPECT imaging fulfil precisely that role. 

 

Route Assessment with Mobile Sensors

Our customer –  Via our contacts in Hi-Def Aerial Surveying, the client for this project was the Federal Rail Authority (FRA) in the US.

The customers problem – The FRA wanted a reliable and effective method to inspect their huge network without closing down sections of track for assessment.

Our view of the problem

The client needed to combine high resolution location, video and odometry techniques to replicate a manual walk along a railway track with the same intuitive interrogation and interpretation of large volumes of data – but without the risks.

Our solution   We developed a mobile sensing system and software suite to provide video survey capabilities from two stereo paired spherical cameras mounted on a rail vehicle platform.

This integrated system was then driven along a network to capture continuous high resolution video, providing visual data that was pre-processed to enable the user to make an accurate remote survey.  Visual odometry techniques were used to locate the sensing system in 3D space and, oncve merged with GPS data, this facilitated the navigation of the survey data via a map interface.

Intelligent UAV Sensor Cueing

Target Acquisition and Sensor Cueing

Our customer –  We were approached to work on the conceptual development of this project by the UK Defence Science and Technology Laboratories.

The customers problem – Current work with Unmanned Aerial Systems (UASs) is limited by the need to combine high fidelity images while maintaining a large field of view.  Multiple imagers were recognised as a solution but there was still the problem of tracking an object in both fields.

Our view of the problem

Not only could we combine a wide field camera to track possible targets with a detail camera to confirm identity but we could also use the same hardware and data to stabilise the UAS, giving additional benefits.

D:EEP with Costain

The partnership approach – A team from Createc is working with partners in Costain to create a contamination measurement technique with the potential to offer huge savings on nuclear decommissioning costs.

The customer – The nuclear decommissioning industry and specialist waste management contractors.

The customers problem – The classification of concrete nuclear wastes is hard to predict and currently only impractical destructive methods are available to measure it accurately.  Sub-optimal waste classification during a decommissioning project can increase waste management costs up to 30 fold.

During decommissioning, our customers need to be able to work out accurately and rapidly exactly where the waste classification boundary sits so that waste volume can be minimised.

Our view of the problem

This is all about seeing beneath the surface and seeing differently.  The radiation coming out of the surface has the history of its journey through the concrete embedded in it in the form of ‘scatter’. To most, this scatter is an unwanted contaminant in a measurement, but we realised it contained the very information we needed.
