The word “nuclear” is no longer a taboo, after the European decision to include it in the glossary of energy sources useful for the ecological transition. The nuclear option, already present – albeit with different nuances - in the program of the center-right parties that won the elections, from today returns to be a piece of Italian energy policy. Ansaldo Energia, Ansaldo Nucleare, the French giant EDF and its Italian subsidiary Edison have announced their intention to collaborate in the development of the new nuclear power plant in Europe, verifying the potential of its application in Italy. EDF is the world's leading producer of nuclear energy; Ansaldo, subsidiary of the State through the Deposits and Loans Fund, develops components and services for the nuclear industry; Edison is the oldest energy company in Europe. In the note in which they illustrate the agreement, the companies argue that nuclear energy is one of the generation sources with the lowest CO2 emissions, ensures a reduced land consumption compared to the installed electrical power and allows optimal planning of production. The plants hypothesized are small modular reactors, which require limited investment and can be used to produce electricity and heat. However, today's announcement raises a lot of controversy. The more time passes since the 1987 referendum, Chernobyl, Fukushima and the other disasters of the recent past, the more the nuclear temptation seems to become unbearable.The invasion of Ukraine has accelerated the search for sources of supply other than the gas and oil imported. And it has opened the door wide to the nuclear option, whose technical and economic aspects are now being discussed, but which no longer seems to be a political taboo.
