A fundamental prerequisite for a sustainable waste management programme is the provision of financial resources to cover the costs of the programme. Developing reliable cost estimates and funding mechanisms can be challenging. Waste management does not stop when the nuclear power plant stops operating. A substantial amount of waste is generated by the decommissioning of the nuclear power plant and the disposal of high-level waste or spent fuel generated by the programme can only be done after several decades of cooling in an interim storage facility. Consequently, the cost of these activities will arise after the closure of the power plant when no revenue on the electricity it generates can be acquired. This means that these costs need to be assessed long in advance and the collected funds need to be managed for several decades. Over that time-span, scientific, technological, economic and societal conditions are likely to change significantly. Cost and funding methods need to take account of the uncertainties that those changing conditions cause and need to be sufficiently flexible to adapt to them. During this webinar, international experts will present approaches to assess the liabilities resulting from the decommissioning of nuclear power plants and the long-term management of the radioactive waste that is generated. This is followed by a presentation on the experience with setting up funds to cover these liabilities.
