The industry of nuclear decommissioning involves the strategic dismantling and clean-up of sites where nuclear power generation has occurred. Companies operating in this sector provide services like decontamination, waste management, and safety evaluation. As old nuclear facilities become defunct and global focus shifts towards renewable energy, this industry is seeing consistent growth. The future vision for this industry is not only limited to the existing decommissioning work of the old plants, but also to consider sustainable waste management in new nuclear power plants being built, especially in parts of Asia and Europe.
