Uranium Enrichment: Analysis of Decontamination and Decommissioning Scenarios

Pursuant to a congressional request, GAO analyzed the adequacy of a $500- million annual deposit into a fund to pay for the cost of cleaning up the Department of Energy's three aging uranium enrichment plants, focusing on four different scenarios, including a: (1) fixed annual $500-million deposit into a fund to cover estimated decontamination and decommissioning (D&D) costs; (2) $500-million annual deposit indexed to an inflation rate to cover estimated D&D costs; (3) fixed annual $500-million deposit into a fund to cover total estimated clean-up costs; and (4) $500-million annual deposit indexed to an inflation rate to cover total estimated clean-up costs.
