A marvel of engineering for our modern age, nuclear power is not without its downsides, radioactive materials must be properly contained to protect citizens and the environment. SPI polyurea is chosen to accomplish the most critical containment challenges in the world.
To avoid an environmental catastrophe, Hanford Nuclear Reservation Tank Farm sourced SPI’s polyurea to contain contaminated wastewater. The tank farm has approximately 172 nuclear waste storage tanks, holding more than 50 million gallons of highly radioactive waste materials.
SPI polyurea was utilized in the encapsulation of contaminated areas within the Canyon Building at the Hanford site. This building stored 19,000 gallons of highly radioactive liquid in four tanks located in process cells below the floor. The contamination was ‘fixed’ by using aerosol fogging to apply a thin coat of fixative to every surface. Polyurea was sprayed on the floor and up the walls as far as workers could reach. After spraying polyurea, contamination levels on the floor of the building were low compared to the levels that existed before the fogging.
SPI polyurea has also been used to line rail cars in the US for transport of low-level radiological waste.
