The UK’s nuclear power is generated primarily by seven advanced gas-cooled reactor (AGR) stations, owned by EDF Energy. AGRs are scheduled to stop generating electricity during this decade, at which point fuel will be removed and transferred to Sellafield for safe storage. AGRs will then be transferred to the Nuclear Decommissioning Authority.
The cost of defueling and decommissioning AGRs will be met from the Nuclear Liabilities Fund, and the government will guarantee any funding shortfall. In June 2021, the Department for Business, Energy & Industrial Strategy announced revised commercial and delivery arrangements for the defueling and decommissioning process.
This study will examine:
- the estimated cost of decommissioning AGRs and the funding available to do so;
- the revised agreements covering the defueling and decommissioning of AGRs; and
- progress with planning for defueling and decommissioning the stations, and risks to value for money.
