How big a customer is CBI
What about the steels used for the various applications cited below. Are you furnishing a similar product or have you furnished products for Hanford or Savannah River?
CB&I Services, a subsidiary of Chicago Bridge & Iron, won a $40 million contract and designed, and installed four stainless steel receipt vessels for the waste treatment plant at Hanford, Washington.
In December 2000, the Department of Energy awarded Bechtel a 10-year $4 billion contract to build the world's largest radioactive waste vitrification plant at Hanford, where more than 240 million litres of chemical and radioactive waste from the plutonium manufacturing process are stored. Bechtel started construction of the treatment plant earlier this year, with commissioning

A significant Savannah River Remediation project that commenced with the arrival of American Recovery and Reinvestment Act funding is the
Effluent Treatment Plant Tank 50 Return to Service Project.
The project began field work in the spring of 2010 and has safely and steadily proceeded with success as Recovery Act construction workers
made headway, first in placing the tank foundation and dike structure where the new Waste Concentrate Hold Tank (WCHT) tank would
eventually reside and most recently in completing fabrication of the WCHT.
Dick Whitehurst, Control Account Manager, said the purpose of fabricating the new ETP tank is to create additional holding capacity where lowlevel
waste concentrate material can be accumulated. On a quarterly basis, the material inventory in the WCHT will be transferred to Saltstone
for final disposition, he said.
Chicago Bridge & Iron (CBI) has been named SRS Safe Subcontractor
of the Quarter for 2010. CBI is the subcontractor responsible for
fabricating SRR’s WCHT, shown on the left. The sitewide award depicts
CBI’s safety commitment, per SRS and DOE safety standards.

new
bubbler technology and other enhancements are soon expected to double the amount
of radioactive waste processed annually at the Department of Energy’s (DOE)
Savannah River Site (SRS).
The bubbler technology, which will be used at the Site's Defense Waste
Processing Facility (DWPF), was modified from existing technology by Catholic
University’s Vitreous State Laboratory (VSL)
During processing, frit and radionuclides are combined in a melter and heated to form molten glass. The bubblers - tubular devices inserted into the melter - blow argon gas through the molten glass waste mixture to maintain an even temperature and allow higher-temperature operation, which produces the best glass form. The superheated mixture is then poured into large stainless steel containers, allowed to harden and stored at nearby SRS facilities.
