DOE nuclear cleanup costs, schedule delays continue to rise, GAO says
The Department of Energy’s Office of Environmental Management faces significant cost increases, schedule delays, and data management issues in completing nuclear waste cleanup projects, according to a new report from the U.S. Government Accountability Office.

A comparison has been made between a modest increase in fuel discharge burnup and repetitive end-of-cycle coastdowns as two near-term alternatives that may be used to improve utilization of resources for a pressurized water reactor on the once-through cycle. Four cases have been considered. The cases include two different burnup levels—present technology of 33 000 MWd/MTU and a 3000 MWd/MTU increase in design burnup to 36 000 MWd/MTU. At each burnup value a fuel cycle without coastdown and one with coastdown every cycle have been evaluated. For each of the four cases, computations have been made of uranium requirements, separative work requirements, and m/kWh(electric) costs. The analyses show that the improvements in resource utilization with end-of-cycle coastdown are modest (<2%). There may be little or no economic benefits. The gains from increased discharge burnup are primarily a reduced fuel cycle cost. Since individual utilities may not see benefits in uranium or separative work savings per se that do not also include dollar savings, implementation of coastdown on a nationwide basis may be difficult.
