Workers are expected to begin mining operations at the US nuclear waste dump in New Mexico for the first time in three years following a radiation release that contaminated part of the underground repository, the Energy Department said Tuesday.
The work to carve out more disposal space from the ancient salt formation where the repository is located will begin later this fall and should be completed by 2020, the department said in a statement.
Workers will remove more than 112,000 tons of salt, making way for seven disposal rooms. Each will have space for more than 10,000 drums containing up to 55 gallons of waste.
