Climatologist James Hansen Defends Nuclear Energy

First time accepted submitter prajendran writes "James Hansen, the former director of the Goddard Institute of Space Sciences, has been a strong defender of using nuclear energy to replace coal and renewable energy. He and three other researchers had written a letter, arguing just this. In this interview with rediff.com, an Indian news site, he was asked to address some concerns surrounding the issue, especially given the strong feelings generated by it. It may not be Hansen's best interview, but it did bring out his passionate side."

    Hey nuclear advocates, how about you fix the waste issue first, then we'll talk.

    Gee, 300 years of storage for a small segment of the waste. The rest of which can be reprocessed into fuel, unless of course you're in the US and have this boogyman fear of plutonium.

    >On the other hand, there is a one small cave in Nevada with some nasty stuff.

    This is the dream solution so far, but this does NOT exist. Hanford - nasty waste tanks buried in the ground. Fukushima - fuel pool at reactor 4 dangerously tipping and leaking. Yucca Mountain plans closed.

    At this point, a lot of nuclear waste sits in fuel pools because there is no long-term solution. We need to get on this and make a place like you describe, pronto. Nuclear can be clean and safe, but so far nobody is really running it clean and safe. Money and greed are too human.

    If you ask questions about our energy future from a nuclear context, you will get nuclear answers. If you think about it from en environmental viewpoint you get environmental answers. If you think about it from the economic perspective you get economic answers. If you think about it from the renewable context you get renewable answers.

    Unfortunately, the solar industry looks at the issue from the context of huge solar power plants instead of dispersed solar installations. That is where the money is. If the solar energy issue is addressed from the dispersed solar context it looks way different. Imagine empowering businesses like WalMart to cover every store with solar panels. Imaging requiring every new home to have solar panels. Imagine retrofitting all the appropriate buildings in the country with solar panels. Imagine the hydroelectric power plants changing their generation schedules to generate at night when solar power goes away, instead of in the day like they do now when demand is highest.

    This can be done much quicker and more cheaply than the nuclear path. It takes twenty years to get a nuke online. Dispersed solar can be online in a year or so. The cost of solar panels comes down almost every day. If you think dispersed solar, the equation changes on everything.

    Seriously, all of the people who freak out about the waste are just being ridiculous. So what if the stuff is dangerous for 10,000 years? We don't have to solve that problem, all we have to do is to keep it safe for a few centuries, and make sure that our descendants understand what it was that we did and what the potential issues are. They'll be better-equipped to deal with it than we are -- and it's a much easier problem for them to solve than a planetary climate that has been pushed to extremes.

    Yeah, it'd be nice if solar, wind and wave energy could address all of our needs, but at present they can't provide the baseload coverage needed to eliminate coal and oil burning.

    Until we have electric trans-atlantic pasenger air transport in six hours, we'll need more than just nukes.

    Transport fuel especially air and ocean needs to remain chemical, even nuclear advocates are pretty unanimous on this.

    0. LFTR for electricity and process heat ASAP
    1. use oil, while it lasts
    2. use synfuel made from coal or natural gas, using Fischer-Tropsch and LFTR heat source
    3. use hydrogen separated from water by energy from LFTR stored as liquid, gas or (preferably) oxide pellets

    With number 3 we have attained a state of complete, virtually limitless energy with extremely small footprint of Thorium mining, zero CO2 emissions and zero use of agriculture for energy production. Oh, and we can make limitless amounts of ammonia-based fertilizer with hydrogen separated from water and atmospheric nitrogen.

    (Nothing but win. Think of me as the hyper 'Trix Rabbit' of Thorium)

    Hey coal/gas advocates,

    The nuclear folks have a better handle on the waste than you do.

    Sincerely,

    The two are NOT equivalent. The US nuclear industry generates about 20% of our national power and 2,300 tons of radioactive waste per year. The US uses about a billion (with a 'b') tons of coal per year for 50% of our national power.

    So if we replaced coal energy generation with nuclear generation, we would have roughly 5750 tons of radioactive waste to handle instead of soot and particulate emissions from burning roughly 174000 times as much mass in coal.

    So you have a choice between unsightly outhouses here and there (storage facilities for nuclear waste) or pissing all over the lawns of everybody all over the country. The difference in scale is mind-boggling.
