Nuclear power plant decommissioning in the U.S. is a complex process overseen by the Nuclear Regulatory Commission (NRC). The process involves safely removing radioactive materials, dismantling structures, and ensuring the site is environmentally sound before license termination. Two main decommissioning options exist, SAFSTOR (safe storage) and DECON (immediate decontamination), with funding requirements determined by the NRC based on technical studies and cost estimations. Multiple agencies participate in the regulatory oversight to protect public health and safety. Numerous reactors have completed or are currently undergoing this process.
