"safe nuclear": Between 1944 and 1971, pump systems drew as much as 75,000 US gallons per minute (4,700 L/s) of cooling water from the Columbia River to dissipate the heat produced by the reactors. Before its release into the river, the used water was held in large tanks known as retention basins for up to six hours. Longer-lived isotopes were not affected by this retention, and several terabecquerels entered the river every day. The federal government kept knowledge about these radioactive releases secret.
