Ministerial Order assessing the industrial reference cost of the Cigéo project
The Ministerial Decree of 30 March 2026 on the costs associated with the implementation of the Cigéo project was published on 1 April 2026 in the Journal Officiel. Cigéo is the French project for a deep geological repository for high-level and long-lived intermediate-level radioactive waste, led by the National Agency for Radioactive Waste Management (Andra).
Funding for the Cigéo project is provided by the nuclear operators involved (EDF, CEA, Orano). Financial provisions for future expenditure relating to this project are calculated on the basis of the costs estimated in the Ministerial Decree drawn up from the data submitted by Andra1. This estimate is updated at key stages of the project’s development (consent to proceed, commissioning, completion of the ‘industrial pilot phase’, periodic reviews).
Following the publication of this new assessment, EDF does not anticipate any significant impact on the level of its provisions compared with the estimates used in the financial statements for the year ended 31 December 2025.

1 The cost is based on a project-specific tax regime, provisionally maintained at the level of the previous assessment set out in the Order of 15 January 2016 concerning the cost of implementing long-term management solutions for high-level and long-lived intermediate-level radioactive waste. The level of this tax will be specified prior to the publication of the decree authorising the construction of the facility.
