Hanford, WA Site - Manhattan Project National Historical Site
The Hanford Engineer Works was built to create large quantities of plutonium at a roughly 600-square-mile site along the Columbia River in Washington State. More than 51,000 workers at Hanford constructed and operated a massive industrial complex to fabricate, test, and irradiate uranium fuel and chemically separate out plutonium.
The Hanford landscape is also representative of one of the first acts of the Manhattan Project, the condemnation of private property and eviction of homeowners and Native American tribes to clear the way for the top-secret work.
At Hanford the park includes:
The T-Plant, a chemical separations canyon, will not be in the park initially, but visitors will learn about its vital role at other locations in the park.
The Hanford B-Reactor National Historic Landmark Tours are offered regularly, from April through September. Visitors can register for tours by internet, phone, or in person. The free, guided tours last approximately 4 hours, including travel to and from the B-Reactor on a Department of Energy (DOE) sponsored bus. DOE will also offer tours of the pre-Manhattan Project facilities during the same timeframe.
