RICHLAND, Wash. – Waste Treatment and Immobilization Plant (WTP) staff at the Hanford Site recently conducted a drill simulating the response to an abnormality in the plant’s power system.
Staff conducted the drill as part of the plant’s Operations Drill Program, which is designed to ensure WTP personnel are prepared to respond to events that could compromise the plant’s operability.
“The program is built to promote a strong, long-lasting operational culture,” said Tom Fletcher, EM Office of River Protection assistant manager and federal project director for WTP. “It’s a key piece in preparing the WTP team and site for future direct-feed low-activity waste (DFLAW) operations to treat radioactive and chemical waste from large, underground storage tanks.”
The program team holds a drill at least once per week, rotating through the operations shift crews and pulling from a wide variety of systems and possible situations. New drill scenarios are created regularly.
“Our program covers any plant system or event not included in the emergency preparedness drill scope,” said Arnoldo Saenz, the WTP operations support specialist who runs the program. “We cover everything from the melter control systems to support systems like cooling water. If it can go wrong, we drill for it.”
During DFLAW operations, treated waste from Hanford’s underground storage tanks will be fed directly to melters inside the WTP’s Low-Activity Waste Facility. The waste will be mixed with glass-forming materials and heated in the melters in a process known as vitrification, then poured into specially designed stainless steel containers for disposal at Hanford’s Integrated Disposal Facility.
