The US Energy Information Administration's nuclear energy data series provides detailed tracking of electricity generation from US nuclear power plants, capacity factors, fuel consumption, uranium supply data, and industry financial metrics. The EIA's monthly and annual nuclear energy data reports are the authoritative government source for these statistics.
EIA data shows that US nuclear generation has remained relatively stable over the past decade despite reactor retirements. The closure of older, single-unit plants in unregulated wholesale electricity markets was partially offset by capacity uprates at existing reactors and the completion of new units at Plant Vogtle in Georgia. The nuclear fleet's generation stability reflects high capacity factors at operating plants.
Uranium fuel cost per kilowatt-hour is among the lowest of any fuel type used in electricity generation, making nuclear fuel cost economics attractive even as plant capital and operational costs are high. The fuel cost advantage reflects uranium's high energy density: a single nuclear fuel pellet the size of a fingertip contains as much energy as approximately 17,000 cubic feet of natural gas.
The EIA also tracks spent nuclear fuel storage, which continues to accumulate at reactor sites across the country pending development of a permanent geological repository. The federal government's obligations under the Nuclear Waste Policy Act to provide permanent disposal have not been fulfilled, creating on-site storage costs that affect plant economics.
