Is the Hanford site still active? Today the Hanford site encompasses 586 square miles. Over time, the plutonium production complex grew to nine reactors, all now closed. Hanford is the site of the only operating nuclear power plant in the Northwest, the Columbia Generating Station operated by Energy Northwest.
Where is the radioactive waste found in Hanford WA? The Hanford Site is a decommissioned nuclear production complex operated by the United States federal government on the Columbia River in Benton County in the U.S. state of Washington.
Why was Hanford shut down? Work was halted at the eastern Washington nuclear site after highly radioactive particles spread inside the most contaminated building on the site.
Is the Columbia River still radioactive? Radiation Myth: The Columbia River isn’t safe because Hanford is poisoning it with radiation. Fact: For many years, nuclear reactors at Hanford were cooled by water from the Columbia. Despite that the reactors have been closed down, there is still radioactive contamination on the site.
