FILE - In this June 6, 2013 file photo, crews from Waste Control Specialists load the first of two containers with low-level radioactive waste from Los Alamos National Laboratory in New Mexico, into a reinforced 8-inch-thick concrete container at the 90-acre federal dump where it will remain forever, on Thursday, June 6, 2013, near Andrews, Texas. The Dallas-based company that now disposes of low-level radioactive waste in West Texas is taking a first step to become an interim storage site for high-level waste. Waste Control Specialists is notifying the Nuclear Regulatory of the company's intent to seek a license to build a facility in Andrews County to store spent nuclear fuel rods from decommissioned power plants for as long as 100 years.
