Game Changers are launching a new series of online Technology Talks. Each session will feature talks on two exciting technology projects which have received funding through the Sellafield Game Changers programme.
The talks are aimed at anyone who is interested in technical innovation in the nuclear industry, learning about cutting-edge research developments and understanding how the Game Changers programme helps solve challenges which can’t be met with off the shelf solutions.
The first session will take place on Tuesday 2nd June from 12 – 1pm using Zoom. Please contact us at firstname.lastname@example.org if you would like to join the session.
Detecting hydrogen at range – David Stothard, Fraunhofer Centre for Applied Photonics
The generation of hydrogen through corrosion or radiolysis is a common phenomenon encountered across Sellafield and can be thought of as a concern or a useful mechanism to monitor the condition of an asset. In either case, it is highly advantageous to detect over extended ranges, without needing to directly deploy instruments in difficult to reach areas.
In this talk, David will present a standalone remote hydrogen detection system which is capable of measuring hydrogen down to a concentration of 0.05%, over distances between 0.1 to 100m. Recently tested in a successful active deployment, Fraunhofer’s system uses only light to make measurements meaning that hydrogen can be detected without placing operators or instruments in sensitive or hazardous areas.
Extending the life of battery powered sensors – Bernard Stark, Sensor Driven
Traditional sensors constantly use battery power, regularly sleeping, waking and measuring when often there is nothing of interest to measure. This typically limits battery lifetime to a few years.
Sensor Driven have developed unique microchips that can extend battery lifetime to decades using minuscule amounts of energy directly from transducer signals, or from leakage currents, to wake up the measuring electronics and take a reading.
In this talk, Bernard will show how this new technology can be used to monitor important information relating to movement, moisture, temperature, noise and more, and present results from recent radiation testing. Considerably extended battery life may have significant potential for Sellafield where sensors need to be used in difficult to reach areas and challenging environments.
