French renewables push nuclear to a corner, EDF closes six power plants

even if France’s major investments in the nuclear sectoror the use of nuclear fission as an energy source to the detriment of renewables. RES has succeeded in sending energy costs to the poor countrywith the recording recorded at the end.

The French case is similar in some respects which happened in Germany at the end of Maywhere the energy generated by the photovoltaic sector (i.e. the unregulated building) has led the owners of large photovoltaic parks to Cut the cost of their energy supply by 87%, from €70.6/MWh to €9.1/MWh.


As reported by BNN Bloomberg, the overproduction of energy from renewable sources led EDF (Electricite de France SA), the French state electricity supplier, to close 6 nuclear plants, including 3 last weekend. Specifically, the systems are: Golfech 2 (1,300 MW), Cruas 2 (915 MW), Tricastin (915 MW), St Laurent 1 (915 MWfrom Saturday to last Sunday at 6:00 pm), Chinon 3 (905 MW) and St Alban 2 (1,335 MW) – both systems were completed between Thursday and Friday and were suspended until the evening of last Monday.

Electricite de France stated that this decision was made in relation to the current situation between energy demand and production, seeing on the one hand the decrease in consumption (- 6 GW) and in another there is an overproduction of RES, that is solar. depending on the amount of sun.

Therefore, it is a special situation, which cannot be seen as a constant trend of growth in RES production and decline in nuclear power, but this is enough for Edf to recalculate the “supply modulation” and create tools “They will start again due to economic conditions.”

Add the heads of the French supplier prices are still rising, for maintenance and construction of nuclear reactors; the ability of they must be eliminatedas is happening now, in relation to a huge economic loss, EDF (heavily indebted) cannot pay.

Today, the state team has decided a 30% increase in construction costs for six new atomic reactors in France, coming to 67.4 billion euros (the estimate for 2021 is 51.7 billion)

To complete the general picture of the situation regarding the development and maintenance of nuclear power in France, in 2023, the ASN (Autorité de Sûreté Nucléaire) has expressed the alarm for the finding a crack 155 mm long and 23 mm deep in one of the reactors. of the Penly nuclear plant, in the north of France.

The damage is calculated with level 2 of the INES scale (International Nuclear Event Scale), a classification system introduced by the International Atomic Energy Agency (IAEA) since 1989.

The accident in the reactor, in that case, had no consequences for the safety of the workers and the surrounding environment, but it raised the level of concern of the ASN about the appropriate conditions and the reliability of the French nuclear park.

Following the report of the ASN, last year, the EDF created an inspection and control plan for all the power reactors in France, carrying out inspections on over 150 repaired welds of RIS and RRA systems, evaluating stress corrosion through ultrasonic tests, according to the submitted protocol. from 2021.

The result of observations presented in a sad state, with old and unreliable systems, because the cracks often reappear in the same places where they appeared the first time. Their constant repairs, showing the bad condition of the house, weaken it, make it more fragile.

In 2022, EDF finds itself operating with half of the 56 reactors that have been shut down for routine maintenance and/or special training to date. “show off” a debt of 64 billion euros.
