Testing and Technology Maturation

AVANTech has the facilities, personnel, and capabilities to perform bench, engineering, and full-scale testing of non-radioactive processes and systems. Many of our technology maturation plans (TMP) are developed and conform to the technology readiness levels associated with U.S. DOE Order 413.3B.

Ion Selective Removal

AVANTech is known worldwide for its capabilities for removal of ion selective contaminants from liquids. Cesium, Strontium, Chromium, and Technetium are some of the ions removed from our designed and fabricated systems. These include our SARRY System at the Fukushima Nuclear Plant, TSCR System at DOE Hanford Site, Wastewater Treatment System at DOE ORNL, and 200 West Groundwater Pump and Treat System at DOE Hanford Site.

– SARRY System, Fukushima Daiichi Nuclear Power Plant, Japan

– Tank-Side Cesium Removal System, DOE Hanford Site, Washington

– Wastewater Treatment System, DOE Oak Ridge National Laboratory, Tennessee

– 200 West Groundwater Pump and Treat System, DOE Hanford Site, Washington

Waste Stabilization and Packaging

AVANTech provides a variety of waste packaging solutions, products, and services, including process shields, shipping casks, steel containers, Radsafe™ High Integrity Contains (HICs), and grout and polymer stabilization systems.

Cask Licensing, Design, and Fabrication

AVANTech has manufactured custom-designed process and transport shields and US/International compliant shipping casks. This capability includes the initial design, licensing, fabrication, and sale/lease stages, ranging from small custom-designed shields to large shipping casks.

Per- and Polyfluoroalkyl Substances (PFAS) Treatment

AVANTech has special processes and systems for removing trace levels of hazardous and radioactive contaminants from water, groundwater, and wastewater, and then properly treating and disposing of any secondary waste. Proprietary products and systems are continually being developed for PFAS and other emerging contaminants of concern.
