How can we handle nuclear waste?

“Goel, an assistant professor in the Department of Materials Science and Engineering, is the primary inventor of a new method to immobilize radioactive iodine in ceramics at room temperature.” Scientist start to find out that the radioactive waste from nuclear related industry can be immobilized into glass or ceramics. I will say it’s the biggest discovery since we start to use nuclear power. As we know, today’s world is trying to find new resources instead of using old limited resources to make the earth be sustainable. Nuclear is definitely one of the best new resources because its huge power. However, the risks is as higher as benefits. We can not image what will happen if nuclear electricity station blows up. Human being also use them to make weapon. Whatever how it be used, it will always created a lot of radioactive waste. Countries put a lot of money to deal the way to use it but also waste a lot of raw material and infect a lot of other resources. Glass and ceramic can be a good proposal but we cannot be 100 percent sure about its safety. I think it will be much better to use the glass that contain radioactive waste to build the facilities of nuclear station. Not for those crucial parts that need to be tough, but for the rest of the building. Since, the nuclear power can also affect water or plants. it is a good idea to reuse those glasses to build multiple-layers barrier to protect the near environment. Another brave idea is that maybe we can distribute those glasses that contains radioactive waste to mountains of small pieces and stack them with normal glasses that used in different ways. So it will largely reduce the dangerous of those glass since they are very small pieces.

    Nuclear waste can be a dangerous material to work with. Especially when it is highly radioactive. This is why I find it hard to believe that nuclear waste could be contained in glass. You spoke of isolating these vessels in faraway places, but even then you would have the problem of radiation to deal with because of the chemical composition of glass. It is not designed to reflect the gamma particles. You would need to have a lead encasing around three feet think to protect the environment from standard high level waste. Since the composition of glass is not too dense you would need an extremely thick piece of glass in order to stop the gamma radiation form infecting the environment. You could encase nuclear waste in glass, but it would take up a whole lot of space. Why make it transparent or in ceramic jars? There is no point unless a denser glass material is created. Of course, low level waste generated from industries could be stored in glass containers, but that would be impractical as it poses very little threat. The only reason would be to put it in a science museum. How is the Iodine-129 immobilized? It would be cheaper to just isolate the radioactive waste where it can’t contaminate anything or re-use it as fuel.
