Biography

Mr. Valdez is a mechanical engineer in the Reactor Materials & Mechanical Design group at Pacific Northwest National Laboratory. He joined PNNL in 2001 after obtaining his BS in Mechanical Engineering from Washington State University. Mr. Valdez’s work is primarily focused on designing and building first of a kind prototypes in support of science research and Laboratory missions. His major contributions include packaging radiation detection equipment for UF6 canister characterization, designing a prototype pickup truck mounted platform for radiation scanning of cargo containers at seaports, and maintaining the control system for the Waste Treatment Plant Pre-Engineering Platform (a ¼ scale test setup of the WTP pretreatment facilities). Mr. Valdez has also contributed to designing and deploying various remote inspection vehicles to several facilities on the Hanford site.
