Submersed Water Purification & Waste Packaging Systems: This system was used for the removing contaminates from a pool of water in which reactor components were being




segmented. The purpose of this water purification system was three fold; first it had to maintain “see the bottom clarity” in a 25’ deep pool, next, it had to lower the concentration of insoluble and soluble radionuclides in the pool; and lastly, the waste produced by the system had to be packaged in a form and concentration that was acceptable for disposal in Barnwell, SC. All the high dose rate components, such as filters, demineralizers and HICs were submersed in the pool where they encountered dose rates in excess of 10,000 R/Hr while lower dose components were placed inside shields on the reactor cavity deck. All components were designed to maintain worker exposure ALARA. Backups were provides for all pumps and similar components to ensure continued operation even during failure or maintenance activities. The most unique aspect of this project was dewatering and packaging all waste generated while the components were submersed in the pool. The A-43 HIC, shown in the “Avantech Overview”, was licensed through the SC-DHEC and utilized for this project. Contact: George Knetl, PCI Energy Systems (847) 680-8100.

West Valley – Hot Cell System

Oak Ridge National Labs – Spallation Neutron Source: AVANTech will design, construct, and deliver filtration and ion exchange purification systems for the SNS Target Vessel Cooling Loops. A key to winning this project was the manner in which AVANTech was able to meet the stringent ALARA goals and standards established by this project. To meet project standards, AVANTech’s proposed an innovative filter and ion exchange column design incorporating lead shielding directly into each components pressure boundary, thereby eliminating the need for large bulky shield walls. Additionally, each ion exchange and filter system has a fully remote system configuration, whereby, spent resin from the ion exchange unit is remotely sluiced out of the column and fresh resin is remotely sluiced in. Similarly, with the filter unit, a remotely operated manipulator opens the vessel and, likewise, remotely removes the one-piece filter assembly. Each pressure vessel is constructed of stainless steel, ASME U-1A stamped, and registered with the National Board. All components are skid mounted allowing for easy movement, placement, and manipulation. Finally, AVANTech provided the SNS Project with both structural and seismic analyses on all aspects of the filtration and ion exchange systems. Contact: Lorelei Jacobs, ORNL, (865) 574-6530.

Hanford Water Treatment Plant




Nine Mile Point – Tank Sludge Cleaning System (TSCS): Provided innovative system for remotely removing sludge, sand and debris. TSCS incorporates the use of a special agitator/ mixing pump and our Solids Separation Collection Vessel (SSCV). The TSCS retrieved sludge, separated and packaged suspended solids associated with the sludge and returned filtered water for reuse. Key differentiators of Avantech’s equipment include fast sludge removal (20 ft3/Hr), elimination of fine particulate in water returned to the plant and minimal use of plant systems and components. Further, the TSCS pre-concentrates (or thickens) the sludge to minimize dewatering efforts. This methodology minimizes sludge handling, particle breakdown, cross-contamination and overall packaging time. This unique system recycled all sluice water back to tank, which eliminated the generation of secondary wastewater for return to the plant. Contact: Joe Amico (860) 930-0459.
