The Mixed Oxide Fuel (MOX) Fabrication Facility located at the Savannah River Site (SRS) near Aiken, South Carolina is one of Superior Air Handling’s largest on-going projects. Superior is installing the HVAC and industrial ventilation systems for the facility which is designed to take surplus weapon-grade plutonium, remove impurities and mix it with uranium oxide to form MOX fuel pellets for reactor fuel assemblies. These assemblies will be irradiated in commercial nuclear power reactors.

Superior Air Handling began pursuit of the MOX project in 2002 and mobilized on the project site in 2009. Superior’s team of over 150 employees has installed roughly 30% of the NQA-1 ductwork and equipment. MOX is one of Superior’s most significant, complex, challenging and rewarding projects due to the unique design of the nuclear processing systems and the strict compliance to NQA-1 quality requirements.

On June 3, 2014, the project achieved over 20 million safe working hours without a lost time incident. One million of those safe working hours were Superior’s.
