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.

Thermoluminescent detectors (TLDs) were applied to measurements of gamma dose rates and their distributions in spent fuel assemblies irradiated in a boiling water reactor, the Japan Power Demonstration Reactor (JPDR). Materials used for the TLD were Mg2SiO4:Tb and LiF. Feasibility of the technique was confirmed by an on-site measurement in a spent fuel pond of the JPDR. The highest gamma dose rate calibrated to a 60Co gamma field was 4 × 103 R/h in the measured positions in a spent fuel assembly, with an average burnup of 5639 MWd/MTM and a cooling time of 8 yr. Reliability of the measurement by means of a TLD was tested via duplicate measurements on a fuel assembly. In the fields of nuclear safeguards and fuel management, application of TLDs will be effective in obtaining inside information of a spent fuel assembly nondestructively.
