Evaluation of Burnup Credit for Accommodating PWR Spent Nuclear Fuel in High-capacity Cask Designs

This paper presents an evaluation of the amount of burnup credit needed for high-density casks to
transport the current U.S. inventory of commercial spent nuclear fuel (SNF) assemblies. A prototypic
32-assembly cask and the current regulatory guidance were used as bases for this evaluation.
By comparing actual pressurized-water-reactor (PWR) discharge data (i.e., fuel burnup and initial
enrichment specifications for fuel assemblies discharged from U.S. PWRs) with actinide-only-based

Connecticut Yankee Atomic Plant Site Officially Decommissioned by the Nuclear Regulatory Commission

The Connecticut Yankee Atomic Power Company (CY) today announced that it has been notified by the U.S. Nuclear Regulatory Commission (NRC) that its former plant site has been decommissioned in accordance with NRC procedures and regulations. The NRC has formally approved Connecticut Yankee’s Final Status Survey Reports in accordance with the License Termination Plan.
