I am a mechanical engineering student who is taking his first chemistry class this upcomming semester. I have a question regarding water and its dilution principles. I have reading up on how Nuclear power plants work. I am curious to how the ocean water disolves and dilutes the radioactive particles form the leak. How does it actually effect the radioactive material? Does that "nuteralized" or "disolved" radioactive material still float around in the water? if it does, is that not harmful? if not, please explain why. My second question, Shouldnt a nuclear power plant be built by the ocean or totally away from it? The reason i ask, Our state, Utah, has approved a nuclear power plant here and they approved it after the japan incident. Thank you much for you help!
