The commissioning and most recent ten-year inspection (VD) dates for these units as of end-2022 are as follows ⁽¹⁾:

At end 2022:

• For the 900MW series, at end 2022, all of the units in operation had undergone their third ten-year inspections. In 2019, the first fourth ten-year inspection (VD4) was successfully conducted on Tricastin 1. Other VD4 were conducted during 2020 and 2021. The programme continued in 2022 with VD4 inspections at Tricastin 3 (completed), Dampierre 2 (completed), Gravelines 3 (completed) and Blayais 1 (in progress).
• For the 1,300MW series, fifteen third ten-year inspections (VD3) were conducted (including Belleville 1 and Cattenom 3 in 2021). Two VD3 were underway as of the end of 2022: Penly 1 and Golfech 1.
• For the N4 series, two second ten-year inspections (VD2) were carried out, at Chooz 1 and Chooz 2. Those of Civaux 1 and Civaux 2 are in progress.

Generation allocation contracts:

In the 1970-80’s, EDF developed, industrial cooperation with European operators in the nuclear industry, in the form of generation allocation contracts backed by units of the EDF French nuclear fleet.

The principle of generation allocation contracts involves assigning a share of the capacity of the units in question to co-contracting parties in exchange for payment of the same share of the unit’s overheads (construction costs, annual operating costs, decommissioning costs, local and specific nuclear taxes, etc.); these parties are sold the same share of the power generated by these units at the variable cost of the fuel (including upstream and downstream fuel costs) throughout their lifetime.

As at 31 December 2022, EDF has within its fleet ten generating units participating in the contracts (up to 1GW) with the following European energy companies:

• Cattenom 1-2: EnBW (5%);
• Bugey 2-3: Électricité de Laufenbourg ⁽²⁾ (17,5%);
• Tricastin 1 to 4: Electrabel ⁽³⁾ (12,5%);
• Chooz B1-B2: Luminus, EDF subsidiary in Belgium (3.3%).
