Integrated Disposal Facility

The Integrated Disposal Facility (IDF) is an engineered disposal site at the center of the Hanford Site. It is designed to receive immobilized low-activity waste from the Waste Treatment and Immobilization Plant and other low-level waste from Hanford Site operations.

The IDF is designed similar to Hanford’s Environmental Restoration Disposal Facility. It currently includes two disposal areas called cells but can be expanded as needed to a total capacity of six cells. The cells are engineered to protect the groundwater. Workers will monitor, collect and treat leachate (water from rain, snow and dust suppression) that reaches the liner at the bottom of the facility.

For more information, please see the Integrated Disposal Facility Fact Sheet.


Design and Construction
The IDF is nearly 1,500 feet wide, 765 feet long, and 45 feet deep, with a capacity of nearly 1.2 million cubic yards.
The depth will accommodate four layers of waste containers separated vertically by 2 feet of soil.
Workers completed Phase 1 of construction (Cells 1 and 2) in April 2006 at a cost of $25 million.
IDF 2Immobilized low-activity waste containers are 4 feet in diameter, 7 feet tall, and weigh more than 7 tons each.
