NUCLEAR POWER


UK FIRST AT SELLAFIELD


AV pilots from Sellafield Ltd’s Engineering Centre of Excellence have flown the first UAV fitted with Lidar sensors at a UK


U


nuclear site. The team based at Cleator Moor in


Cumbria flew the Swiss-made Flyability Elios 3 as part of a decommissioning programme at the site. The UAV is capable of carrying the


latest Lidar technology, creating 3D visualisation which gives the pilot full situational awareness while flying the drone. The images are also stored for 3D mapping reference, data that can be output for design work and for decommissioning. The quadcopter, which uses


ducted propellers, can be used to fly in hazardous environments such as active cells, taking away the need to involve humans in those areas. Sam Jay, UAV Engineer and Chief


Pilot at Sellafield Engineering Centre of Excellence, said: “We are going to be able to model an area of the site that people have not been into before.” Peter King, Technical Specialist at the Centre of Excellence, said: “The technology we are using will enable us to understand decommissioning requirements for inaccessible areas. “It will enable us to carry out a high-quality inspection, changing aspects of decommissioning, enabling us to characterise areas without putting people into those environments.” The drone is able to operate in


complete darkness with specialist thermal cameras and oblique lighting, inside full concrete cells and at a distance of up to 500m from an


operator. The UAV team at Sellafield


Engineering Centre of Excellence are well known across the industry for setting the standard in safe use of drones at UK nuclear sites. ●

RELIABLE DETECTION AT NUCLEAR PLANTS ngineers responsible for nuclear


alarms and indicators for use in liquid, air, gas, or for interface service will find the FLT93 Series Switch from Fluid Components International (FCI) provides a nuclear safety qualified


E


solution. The FLT93 Switch


from FCI provides dependable critical


equipment protection and plant integrity validation that makes it Ideal for use in a wide range of nuclear power plant flow, level and temperature measurement


applications. Applications include: reactor core


power plant operations who need flow, level, or temperature


coolant, level interface detection and temperature, pump protection, flood alarm, condensate pot level and turbine water level.


It is ideal in any


application where the measurement of both flow and temperature or level and temperature are important.


FCI’s proven single sensor


design provides dual measuring functions with the FLT93 Switch. It helps nuclear plant operations save weight, space and


costs over two or more


discrete sensors. Operators also realise reduced qualification installation costs and complexity. Its multi-parameter measurement design is based on more than 55 years of flow and level switch engineering and application experience, providing a rugged long- life instrument.


Long an innovator


dedicated to the nuclear power industry, FCI’s original models 12-64, 8-66 and FR72 were installed when the first commercial nuclear power plants were built and are just now being replaced by the FLT93 Series. These models have survived the initial operating licenses and are being replaced under license extension renovations. The new switch has an analogue


design that is fully qualified for Class 1E safety related nuclear power plant applications, having been extensively tested to IEEE 323 and IEEE 344 as well as meeting the requirements of MIL- STD-461 and EN/IEC61000. Both the insertion and in-line sensor versions are qualified for 40-year life at 150°F. The FLT93 sensor is qualified to radiation levels of 2x108 rads. ●
