Beginning Monday and extending through the end of the year, trucks loaded with thousands of tons of radioactive waste will pass through the St. Louis area on their way to a temporary resting place in Texas.
More than half of the waste will be making its second visit here. It came from the Mallinckrodt Chemical Works on the riverfront just north of downtown. Mallinckrodt, an atomic-age pioneer, altered the course of World War II by developing a way to purify uranium to the grade needed to make the atomic bomb.
After the war - in the 1950s - 6,000 tons of radioactive byproducts from the processing were shipped to a uranium processing plant northwest of Cincinnati, where it was kept in silos. There it has stayed for the last half-century. But now the Department of Energy is intent on cleaning up the site at Fernald, Ohio, and shutting it down for good because it's located near a major water supply and heavily populated areas. That means finding yet another home for the waste. <snip>
