HotSense™ enable online, high-temperature gas void detection to reduce personnel dose, reduce costs and increase safety
Ionix HotSense™ sensors have been deployed for gas void monitoring in leading US nuclear power stations. Overhead cooling lines which are routinely flooded must be inspected to ensure they do not have any trapped air in the form of voids. These measurements are currently performed manually using an inspector. This requires access to high areas via rope or scaffolding and potential radiation dose exposure. HotSense™ fixed transducer provided a solution which could be accessed from ground level to:
- Minimise exposure to staff by reducing the time spent in the environment
- Reduce the cost of inspection by removing the need for repeated rope access and scaffolding
- Increase overall plant safety by reducing the exposure of staff to working at height.
- Simplify data collection and improve measurement reliability compared to manual inspection.
- The HotSense™ sensors were quick and easy to install using the supplied coupling and clamping systems.
- The HotSense™ sensors performed showed stable performance both immediately after installation and following 3 months in operation.
- The sensors operated to NDT transducer standards and were compliant with current measurement procedures.
- Transducer cable extensions allowed data to be safely collected from ground level minimising the exposure of staff to working at height and reducing their radiation exposure time.
- Plant and operator safety was improved due to the application of the HotSense™
