    How much higher will the exposure to marine life be with those 9 reactors at the bottom of the ocean above background? This, too, is calculable.

    I'm not worried about small levels of radiation (that will not even be a blip on the radar when compared to the whole) because I know that there are much higher sources of radiation in our everyday lives. I was exposed to less radiation working around nuclear reactors for the Navy for 9 years than most people get in just one year from natural sources. I know what goes into our reactors and at least some of the designs to help prevent them from becoming huge ecological problems if they are left at the bottom of the ocean.

    No, nothings perfect. But nuclear power is no where near the ecological disaster that fuel and other petroleum products are, especially when it comes to being in the ocean. In fact, if I were you guys, I would be much more worried about the nuclear weapons on that ocean floor than those reactors.
    "Hot" refers to radioactivity, I know that the ocean water will keep the rods cool. The reactor vessels are designed to resist pressure from within, not from without. I know that the reactor vessels are usually 5 inches thick stainless and also that if they are perfectly round, they could withstand great external pressure. I do not believe that is the case. Your comment on the warheads is prescient. Since lightweight is paramount in missile design, I suspect those perhaps12 pound chunks of plutonium might already be exposed. I observe the human track record objectively and deduce that the species is not prepared for the "RESPONSIBILITY" that is demanded by nuclear technology.

    I realize that "hot" is referring to radioactivity. I was asking how "hot" you believe they would be after so much time. It is calculable, I assure you. In fact, you could even make some assumptions and come up with a rough estimate.

    We are just as prepared for the responsibilities of nuclear power as we are for a multitude of other technologies that we have in this world. Hell, we had nuclear weapons before we had nuclear power. Coal and gas can do major damages to our ecosystems. In fact, just building communities, especially cities, does major damage to ecosystems. We have trash building up. I would go as far as saying capitalism itself does much more damage to our planet than nuclear power ever could, considering some of the demands capitalism puts on the environment in the name of supply and demand.

    "There are 92 known cases of nuclear bombs lost at sea."

    See: Lost nuclear bombs "


    http://didyouknow.org/nuclear/



    List of collisions of ships with nuclear bombs:


    N-BASE - Submarine accident list


    "Accidents involving American and Soviet ships, bombers and rockets have left at least 50 warheads and nine nuclear reactors scattered on the ocean floors since 1956, according to a comprehensive study of naval accidents that was released today."

    Dozens of Atomic Warheads Lost In Sea by Superpowers, Study Says - NYTimes.com

    Search: Nuclear Bombs Lost at Sea


    "Will future generations suffer because of our carelessness? Could be! Imagine a nuclear weapon somewhere in the ocean and after a few hundred years the casing gets so corroded that the nuclear material leaks out into the water. The tides carry the contamination for hundreds or thousands of miles. This would effect the marine life. People would eat the fish and then the mutations and sickness would start. I am sure that this will be denied but I think that we as intelligent people all know better."


    About Facts Net


    "Three of its four bombs broke on impact, and tons of radioactive ice and debris were recovered. But new documents show that one of the four B28 thermonuclear weapons, with a yield of between 70 and 350 kilotons, may still lie on the seabed.'

    I don't think you have a good grasp of the math involved.
