Washington River Protection Solutions (WRPS) is reducing the risk to the environment posed by Hanford’s 56 million gallons of highly radioactive and chemical waste stored in 177 underground tanks.

WRPS is the U.S. Department of Energy Office of River Protection’s prime contractor responsible for safely managing the waste until it is prepared for disposal.

The tank waste is material left over from years of World War II and post-war production of nuclear weapons. The waste is stored in 149 older single-shell tanks and 28 newer and safer double-shell tanks that are grouped into 18 farms near the center of the 586-square-mile Hanford Site in south-central Washington.
