ENGINEERING. PRACTICE. POLICY. 47 August/September 2018 unmanned systems inside COLLECTING RADIATION LEVELS WITH TRADITIONAL METHODS There are different ways radiation levels are collected, depending on the area in the facil- ity. In containment, personnel responsible for monitoring health hazards at the facil- ity survey areas to identify acute radiation zones, said Tony Cinson, senior technical leader—nuclear plant support nuclear sector for Electric Power Research Institute (EPRI). They typically use Geiger counter technology for these assessments, but also wear other de- tection measurement technology such as elec- tronic personal dosimeters (EPD) and ther- moluminescent dosimeters (TLD). Because of concerns of overexposure, it can be difficult for personnel to obtain measurements in cer- tain places, such as confined spaces and areas at higher elevation. Area Radiation Monitors (ARMs) are also strategically located throughout the radio- logically controlled area (RCA), Cinson said. These monitors are connected to alarming systems to alert personnel when radiation levels are nearing limits that aren't expected during normal operation. External radiation monitors are located at fixed positons outside the RCA, Cinson said, and in the neighboring communities, provid- ing plant and emergency responders with in- formation about the spread of contamination in the event of an accident. These sensors have their limitations, though, because they are fixed in one location and can't provide a com- prehensive radiation survey of the facility. THE BENEFITS OF USING DRONES INSTEAD Drones can help acquire radiation levels dur- ing routine monitoring and after accidents. "Using UAVs to detect radiation in a post-ac- cident scenario would be extremely beneficial," said Sam Johnson, technical leader—nuclear plant support for EPRI. "The systems would allow us to map the radiation levels within an area so we know where we can safely send personnel and where we can't. UAVs f lying through the air move faster than a person in a vehicle who has to follow the roads. If we have a pre-planned mission for a UAV to f ly, there's also a time-saving factor." Charlotte UAV recently began working with Mirion Technologies and RADeCO Inc. to of- fer this type of solution. PUING TRUST IN UAS IN NOVEMBER, EPRI WORKED WITH CHARLOTTE UAV AND HAZON SOLUTIONS to complete a trial inspection of a containment structure at a Southern Company plant. To read more about that mission and how the nuclear industry is using UAS for these and other types of inspections, read "Nuclear Industry Putting Trust in UAS" at THE ZOE The Zoe is an all weather quadcopter from FlyCam UAV that features up to 40 minutes of flight time. " THE IDEA IS WE'RE GOING TO ELIMINE THE NEED TO PUT LIVES AT RISK BY USING AN AERIAL ROBOT." Corey Hitchcock, UAS standardization pilot, Southern Company RADIION DETECTION
