EDF / 2020 Universal Registration Document

1 THE GROUP, ITS STRATEGY AND ACTIVITIES Description of the Group’s activities the N4 series, which is the most recent with an average age of 20 years, consisting of 4 operating units (for a total power capacity of 5,990MW); That is a set of 56 units, on 18 different sites (after the permanent shutdown in 2020 of the two 900MW Fessenheim units) owned by EDF, constituting total authorised capacity of 61,370MW at 31 December 2020. With an average age of approximately 35 years, EDF’s nuclear fleet is about average compared to the fleets installed worldwide.

EDF’s nuclear fleet in France and its operation 1.4.1.1.2.1 EDF’s PWR model is divided into three series of available electrical power: a 900MW series consisting of 32 operating units of (for a total power capacity of 29,010MW) with an average age of 38 years; a 1,300MW series consisting of 20 operating units of (for a total power capacity of 26,370MW) with an average age of 32 years;

The commissioning and most recent ten-year inspection (VD) dates for these units as of end-2020 are as follows:

The fourth ten-year inspection of Bugey 2 and the third ten-year inspection of Belleville 1 were concluded at the beginning of 2021. *

At end-2020, all of the units of 900MW in operation had undergone their third ten-year inspections. Those of Chinon B3 and Chinon B4 units were completed in 2020. In 2019, the first fourth ten-year inspection was successfully conducted on Tricastin 1. The second was in 2020 at Bugey 2 (completed in early 2021). For the 1,300MW fleet, 13 third ten-year inspections were conducted, one third ten-year inspection was underway at the end of 2020 (Belleville 1, which was completed at the beginning of 2021), and 6 are still to be carried out. For the N4 series, two second ten-year inspections were carried out, at Chooz 1 and Chooz 2; two others (at Civaux) are pending. EDF first-generation design plants have been gradually shut down and are currently being decommissioned. The Fessenheim plant has also been shut down in 2020 (see section 1.4.1.1.2.3 “Decommissioning of nuclear power plants”).

Regulatory notice

Regulations applicable to basic nuclear facilities (BNFs) After completion of a procedure set out in the French Environment Code (c ode de l’environnement) , the construction of a BNF is authorised by a decree issued by the French Prime Minister after consulting the French Nuclear Safety Authority ( Autorité de sûreté nucléaire , ASN) and on the basis of a report produced by the Minister for Nuclear Safety. The authorisation to commission a BNF is issued by the ASN, also on completion of a procedure set out in the French Environment Code. The general regulations applicable to basic nuclear facilities, among other issues, make the protection of public safety, health and sanitation, nature and the environment (the “protected interests”) a priority.
