The main purpose of this legislation is to enhance safety protocols at commercial nuclear power plants that have permanently shut down. It aims to ensure that there is a dedicated inspector on-site to oversee the decommissioning process and the transfer of spent nuclear fuel to dry storage. This is important to prevent any potential safety hazards during these critical activities. Key provisions of the legislation include the requirement for the Nuclear Regulatory Commission to assign a resident inspector to each decommissioned nuclear power plant.
