Then it s sealed in a steel drum. I m not talking about the kind of drum musicians use I mean a huge steel barrel that is welded shut and then washed thoroughly. Of course after that you still have to put the drums somewhere because there is still a chance that the radioactive material will corrode the steel and seep out. Also another problem with the radioactive waste is actually storing it. There are a lot of uh . a lot of ideas on this. And you know there um there isn t any answer that makes everyone happy. But one thing to do with nuclear waste is to simply store it in huge storage bunkers. Scientists can kind of watch it then monitor it to make sure it doesn t leak. Plus the really dangerous parts start to decay after a few decades. So if they do decide to do something else with them it s not as much of a risk of contaminating things that are exposed to it. OK. So that s one way of disposing of nuclear waste. Another common way of disposing of it is to put it in a secluded area of the environment-you know like underwater or buried underground. Oh yes . this neutralizes its immediate danger to humans but the danger to the environment is still massive. 1 mean who knows what it could do tothe vegetation and the animals in the area Underwater it could put marine creatures at risk. A lot of concerned that-long-term anyway-this could cause even more damage than most of the other options. They don t want j to put the environment at risk just to store j nuclear material i Transmutation is an option that is being explored I as well. It uh it involves . . . it s kind of like i changing the chemical makeup of the radioactive material into a type of nuclear waste that is less I. radioactive. It uses nuclear reactors to process i the material and make it less dangerous. r .
