Under an agreement between the State of Idaho and the U.S. government, reached in 1995, U.S. Department of Energy and U.S. Navy provide the state with information about spent fuel shipped to the Idaho National Laboratory. The chart above and the table at the end of the message summarize this information as of the end of 2023.

The information is published by the Idaho Department of Environmental Quality as a document "Cleanup Progress at the INL under the 1995 Settlement Agreement". The document is regularly updated and contains information about two most recent calendar years. Here are archived copies of the document with information for 2019-2020 and 2021-2022, and 2022-2023. Earlier information, published in 2018 and 2019, used data provided by the Snake River Alliance.
