The licensee must be able to identify and track the amounts in the trust fund applicable to radiological decommissioning activities and the amounts set aside for spent fuel management and other uses. During operation, unless otherwise approved through a regulatory exemption, funds collected and set aside in the DTF for decommissioning are exclusively for radiological decommissioning as defined in 10 CFR 50.2. Therefore, expenses that these funds can be used for include expenses directly related to removing a facility or site safely from service and reducing residual radioactivity to a level that permits license termination and release of the property for restricted or unrestricted use. These expenses may include: • Expenses directly related to activities that satisfy the definition of “decommission” in 10 CFR 50.2; • Expenses directly related to decommissioning planning and execution including consulting and paper studies, environmental assessments, engineering, and licensing activities; • Expenses directly related to the decontamination and dismantling of systems, structures, and components (SSCs) (labor, materials, and equipment), including disposal of waste generated from decontamination and dismantling activities; • Expenses directly related to the disposal of contaminated SSCs (labor, materials, and equipment); • Expenses directly related to radiological soil remediation (labor, materials, and equipment), including disposal of this waste; DG-1347 Revision 1, Page 10 • Expenses directly related to overhead costs (i.e., emergency planning and security) and energy (e.g., electricity and fuel) used in support of decommissioning activities and to maintain the safety and security of the site; • Expenses directly related to undistributed costs such as property taxes and nuclear insurance required while in decommissioning until the license terminated; • Expenses directly related to improving the efficiency and
