Feds: Underground nuclear waste tank at Hanford Nuclear Reservation may be leaking

Feds: Nuclear waste tank at Hanford Nuclear Reservation may be leaking,    Statesman Journal NICHOLAS K. GERANIOS, 30 Apr 21, Associated Press   SPOKANE, Wash. (AP) — An underground nuclear waste storage tank in Washington state that dates to World War II appears to be leaking contaminated liquid into the ground, the U.S. Department of Energy said Thursday.

It’s the second tank believed to be leaking waste left from the production of plutonium for nuclear weapons at the Hanford Nuclear Reservation. The first was discovered in 2013. Many more of the 149 single-walled storage tanks at the site are suspected of leaking.


Tank B-109, the latest suspected of leaking, holds 123,000 gallons of radioactive waste. The giant tank was constructed during the Manhattan Project and received waste from Hanford operations between 1946 to 1976.

The Hanford site near Richland in the southeastern part of the state produced about two-thirds of the plutonium for the nation’s nuclear arsenal, including the bomb dropped on Nagasaki, Japan, and now is the most contaminated radioactive waste site in the nation.

A multi-billion dollar environmental cleanup has been underway for decades at the sprawling Hanford site.

The Washington state Department of Ecology and the U.S. Environmental Protection Agency were notified Thursday that the tank was likely leaking…….

The leak from Tank B-109 was first suspected in March 2019, when there appeared to be a small drop in the level of its liquid waste. Monthly checks showed the level stable until July 2020, when another drop was detected, and the DOE launched an investigation. https://www.statesmanjournal.com/story/tech/science/environment/2021/04/29/feds-nuclear-waste-tank-hanford-nuclear-reservation-may-leaking/7401579002/
