What Is Hanford?

The Hanford Site in southeast Washington is the location of the world's first full-scale nuclear reactor, the only free-flowing stretch of the Columbia River in the United States, and a $2 billion per year federal cleanup project.

In producing plutonium for nuclear weapons, reactors and processing facilities at Hanford generated millions of gallons of high-level radioactive and chemical waste and millions of tons of low-level waste. Three government agencies and more than 8,000 workers now cooperate to address the environmental problems associated with these wastes and ensure the safety of the surrounding region.

In addition to information about Hanford history and cleanup, you will find video interviews with government representatives, links to other online resources, and a simple form for educators to connect with HanfordLearning.org for assistance with creating tailored lesson material.
