90+% of it can be re-used in the future EPRs and 4th gen reactors, and transformed to low-level waste which are way less radioactive.
The most radioactive waste are those which deplete the fastest. You don’t have to store those ones for millions of years, we’re talking about decades or 2-3 centuries at most.
It’s sealed and not going anywhere and it can definitely wait years, even decades, for something like Cigéo to be built.
Stop pretending it’s some kind of unsolvable problem, nuclear engineers have solved it decades ago, it’s just anti-nuclear folks that oppose all solutions provided.
