Most nuclear power plants on earth have only a 50 year life span at most

Since many of these nuclear power plants were set up in Russia and elsewhere on earth in the 1950s it is only logical that they are going to start failing all over the place. There are really not contingincy plans in place to deal with this situation worldwide (Not Really).

The best they can do is to cover everything like Chernobyl in 10 feet thick of cement everywhere and this doesn't protect the water table from ongoing radiation wherever that is. it might protect the air but that's all from more contamination.

Also, people who put in that 10 feet thick coat of cement in likely will die when they do this or withing a year or two unless you have robots do it.

This is what is now coming  from this short sighted approach to nuclear power plants world wide from now on.

So, plants set up in the 50s are already failing many places on earth as I write this. This is only logical. They were not designed to last this long by engineers. Nor could they have been designed to last this long. This is just the hard truth about what people and governments in the 1950s have done to us all worldwide.
