Centrales nucléaires, démantèlement impossible?

From France to the United States via Germany, the countries which have bet on nuclear energy are today faced with a new challenge: the dismantling of their aging or permanently shut down plants. Forty years ago, their designers did not foresee that, having become too old and therefore dangerous, these reactors would one day have to be dismantled, and that their highly radioactive waste would have to be stored. While operators and nuclear safety authorities ensure that they can control this dismantling process, the reality is quite different.
