The Hanford Site occupies 586 square miles (1,518 km 2) – roughly equivalent to half the total area of Rhode Island – within Benton County, Washington. [1] [2] It is a desert environment receiving less than ten inches (250 mm) of annual precipitation, covered mostly by shrub-steppe vegetation.
Upstream of the Hanford Reach is Priest Rapids Dam and downstream is the McNary Dam, which also impounds the last stretch of the Snake River, the largest tributary of the Columbia. The Hanford Reach includes the still extant Coyote Rapids [1] [2] and supports over forty species of fish including significant numbers of spawning fall chinook ...
The B Reactor at the Hanford Site, near Richland, Washington, was the first large-scale nuclear reactor ever built. The project was a key part of the Manhattan Project, the United States nuclear weapons development program during World War II.
Bechtel National has received its highest ever annual rating for its work on the Hanford site’s vitrification plant for 2022.. The Department of Energy said it earned 83% of the incentive pay ...
A second legal challenge to the award of a $45 billion contract for environmental cleanup work at the Hanford nuclear site in Eastern Washington has been denied.. U.S. Judge Marian Blank Horn ...

The N-Reactor was a water/graphite-moderated nuclear reactor constructed during the Cold War and operated by the U.S. government at the Hanford Site in Washington; it began production in 1963.
The Vit Plant will first process Hanford's low-activity waste liquids, starting as soon as 2023, as part of the Department of Energy's Direct-Feed Low-Activity Waste (DFLAW) approach. Under DFLAW, waste will be sent from the tank farms to the Vit Plant's Low-Activity Waste Facility for vitrification.
Hanford Reach is home to nine nuclear reactors of which B Reactor is the most famous; constructed in 13 months during World War II, it was the world's first full scale reactor. Plutonium from the reactor was used in physics package for the first nuclear detonation at the Alamogordo Bombing and Gunnery Range in New Mexico (July 16, 1945) and in ...
