OK, this isn't a very comforting news. It seems that one of the material used to store nuclear wastes generated from nuclear plants deteoriates even faster than first thought.
It is no question that storing these material for that long is a daunting task. This is not a permanent solution, and it shouldn't be. If we are to continue using the same technology to generate power from nuclear plants, then without reprocessing, or even the use of breeder reactors, then we will continue to face this problem.
Unfortunately, with the current climate on scientific funding, how much money do you think will go into studying this?
