An innovative radiological control simulator plays a key role in the training process for technicians at the Hanford Site’s Waste Treatment and Immobilization Plant (WTP). Called VIZRAD Frisk, the simulator allows technicians to get experience screening for contamination.

“Implementing new technologies to enhance training is just one of the many ways WTP staff members are improving operational culture,” said Tom Fletcher, EM federal project director for WTP. “Their constant innovation shows their dedication to the mission and adapting to technical challenges.”

VIZRAD Frisk allows instructors to virtually “paint” simulated contamination onto a life-sized mannequin using a laptop. Technicians then practice their screening techniques on the mannequins using VIZRAD’s specially designed probe. The probe detects signals transmitted by sensors in the mannequin and provides visual readings and audible cues when it detects an area of virtual contamination. The sensors also track the probe’s location, speed and distance, allowing instructors to ensure that technicians are using the proper techniques.

“The VIZRAD system is instrumental in training, as it allows people to learn before we start actual radiological operations,” said Rick Holmes, general manager for Waste Treatment Completion Company, a subcontractor to Bechtel National Inc., which is designing, building and commissioning the WTP for EM’s Office of River Protection. “It allows us to safely and effectively train individuals up to full certification and prepare them for future operations.”
