The cumulative disbursements of nuclear expenses (based on gross values at year-end economic conditions) are distributed as follows:
| 2021 | |||
|---|---|---|---|
| Costs based on year-end economic conditions | |||
| Provisions related to nuclear generation within the scope of the Law of 28 June 2006 (in millions of euros) | Disbursement expected within 10 years | Disbursement expected after 10 years* | Total |
| Spent fuel management | 7,846 | 8,275 | 16,121 |
|
540 | 2,742 | 3,282 |
| Long-term radioactive waste management | 5,116 | 31,663 | 36,779 |
| Back-end nuclear cycle expenses | 12,962 | 39,938 | 52,900 |
| Decommissioning of nuclear plants in operation | 347 | 20,132 | 20,479 |
| Decommissioning of shut-down nuclear plants | 2,903 | 4,815 | 7,718 |
| Last cores | 262 | 4,087 | 4,349 |
| Decommissioning and last core expenses | 3,512 | 29,034 | 32,546 |
*Over a 20-year and 50-year horizon, 20% and 41% respectively of cumulative disbursements (at year-end economic conditions) will concern long-term radioactive waste management provisions, and 32% and 96% respectively will concern decommissioning provisions.
This approach can be complemented by estimating the impact of a change in the discount rate on the discounted value.
The following table reports these details for the main components of EDF’s provisions for the back-end of the nuclear cycle, decommissioning of nuclear plants and last cores:

Other provisions for decommissioning principally concern fossil-fired power plants.
The costs of decommissioning fossil-fired power plants are calculated using regularly updated studies based on estimated future costs, measured by reference to the charges recorded on past operations and the most recent estimates for plants still in operation.
The provision recorded at 31 December 2021 reflects the most recent known cost estimates and includes rehabilitation costs for generation sites.
