The U.S. Department of Energy (DOE) has decided to build an interim aboveground storage facility for two failed melters from the Defense Waste Processing Facility, instead of using underground storage. This move frees up space in the underground storage for melters with higher radiation levels. An analysis found that the environmental impacts of this change are not significant, and therefore, no further environmental review is needed. Because the situation aligns with past findings, no additional mitigation is required.
Simple Explanation
The government has decided to keep some very big, broken machines that used to help manage waste inside a special new building above the ground instead of underground, which will leave room underground for even bigger machines that need it more. They checked to make sure it wouldn't hurt the environment, and they think it will be okay.
