The Nuclear Regulatory Commission is amending its regulations on the decommissioning procedures that lead to the termination of an operating license for nuclear power reactors. The final amendments clarify ambiguities in the current rule and codify procedures that reduce the regulatory burden, provide greater flexibility, and allow for greater public participation in the decommissioning process. Some minor amendments pertain to non-power reactors and are for purposes of clarification and procedural simplification. The Commission believes that the final amendments will enhance efficiency and uniformity in the regulatory process of decommissioning nuclear power plants.
