SALT LAKE CITY - Utah's Radiation Control Board has ordered a company that wants to import nuclear waste into the state to first submit a report confirming additional safeguards will work.
The board voted Tuesday to require EnergySolutions Inc. to complete a "site performance assessment" before additional depleted uranium comes to Utah.
The move comes less than a month after the board refused to block the company's plans to dispose of depleted uranium waste from the Savannah River Site, a former nuclear weapons complex in South Carolina.
Nearly 15,000 drums of the depleted uranium were slated to start arriving in December at the company's facility about 70 miles west of Salt Lake City. But the company does not expect the updated assessment to be done until December 2010.
Never miss a local story.
Depleted uranium is different from other low-level radioactive waste because it becomes more radioactive over time for up to 1 million years. The Nuclear Regulatory Commission recognized that distinction earlier this year and is taking public comments on how it should be handled.
