A truck loaded with waste crosses the scale at the East Tennessee Technology Park at Oak Ridge. Each truck used by Oak Ridge contractor UCOR is equipped with a unique radio frequency identification card that logs its movements and weight and registers the data in a database.

UCOR, the primary contractor for the Department of Energy’s Oak Ridge Office of Environmental Management (OEM), recently transitioned to a new waste tracking system that improves how shipments are tracked from work sites to disposal locations.

The new system includes upgraded radio frequency identification (RFID) tracking for trucks, as well as new hardware and software, allowing for an automated tracking operation that delivers up-to-the-minute waste disposal data.

Markey, Levin introduce spent fuel legislation

Levin

Sen. Edward J. Markey (D., Mass.) and Rep. Mike Levin (D., Calif.) have introduced the Nuclear Waste Task Force Act. The legislation is intended to establish a new task force to consider the implications of amending the Atomic Energy Act of 1954 to remove exemptions from environmental laws for nuclear waste. Eliminating this loophole could help enable consent-based siting of long-term storage solutions for spent nuclear fuel and high-level radioactive waste, the lawmakers said.

Intended to continue the work of 2012's Blue Ribbon Commission on America’s Nuclear Future, the task force would also be responsible for providing a clear explanation of what constitutes “consent-based siting.”

GAO urges Congress to address spent fuel stalemate

Congress needs to take action to break the impasse over a permanent solution for commercial spent nuclear fuel, according to a report by the U.S. Government Accountability Office. The GAO recommends that Congress amend the Nuclear Waste Policy Act (NWPA) to authorize a new consent-based siting process, restructure the Nuclear Waste Fund, and direct the Department of Energy to develop and implement an integrated waste management strategy.

The GAO also recommends that the DOE finalize the consent-based process it began in 2015 for siting consolidated interim storage and permanent geologic repository facilities. The DOE agrees with that recommendation.
