Watts Bar Unit 2 Is The First New US Nuclear Reactor In Decades (washingtonpost.com)

tomhath writes from a report via The Washington Post: The Tennessee Valley Authority's (TVA) Watts Bar Unit 2 is the first nuclear reactor to come online since 1996, when the Watts Bar Unit 1 started operations. The new reactor is designed to add 1,150 megawatts of electricity generating capacity to southeastern Tennessee. By summer's end, authorities expect the new reactor at this complex along the Chickamauga Reservoir, a dammed section of the Tennessee River extending northward from Chattanooga, to steadily generate enough electricity to power 650,000 homes. But while nuclear reactors account for the lion's share of the carbon-free electricity generated in the United States, the industry faces this new set of circumstances in a state of near-crisis. A combination of very cheap natural gas and deregulated energy markets in some states has led to a growing number of plant closures in recent years. A new report from Bloomberg New Energy Finance says that renewable energy, including solar, wind and hydroelectric will overtake natural gas as an energy source by 2027.

    Its good to see new reactors come online, but I wish we had the balls to licence new reactor designs that are passively safe.

      I think renewables are a great addition to the energy mix, but I just don't see any realistic scenario where we could jump from our current situation straight to renewables. Safe nuclear is an enormous pollution saver even if you count in the whole supply chain. With population growth and electric vehicles behind the corner, there's going to be an enormous growth in energy demand and without either nuclear or fossil fuels, we likely can't meet that demand.

      A big problem with maxing out renewables is that the uneven nature of those power sources means very large amounts of natural gas needs to be burned to make up the shortfalls when the wind isn't blowing or the sun isn't shining. Nuclear is a much better source of "green" energy.

    Meanwhile, the federal government continues to massively over-regulate nuclear energy and does other brain-dead things. For example, if you operate a coal power plant and do nothing other than routine maintenance, then you are grandfathered to whatever environmental standards were in effect when it went into operation. On the other hand, if you decide to make "major" improvements, the entire operation must now come into compliance with current regulations. Naturally, operators are lining up to upgrade and increase the cost/regulatory burden of their operations. Not!

    Thankfully, natural gas is relatively clean, but it won't last forever. Our broken policies have resulted in nobody wanting to touch the best energy source in modern history (nuclear) and while the government and environmentalists continue tripping over themselves to throw wads of cash at companies in the "renewable" space, those old coal power plants continue to emit more radioactive contaminants then even the oldest nuclear power plants because we actually make it more expensive for the operators to fix it than to just leave it as is. To top it off, rather then devoting serious effort into spent nuclear fuel reprocessing (like into a form usable in modern reactor designs), we keep loading it in leaky drums and burying it in the ground because nobody will build a new reactor because nobody wants to spend 100 years and $100B to get a new reactor going.

      Now that Harry Reid is leaving we might actually be able to bury nuclear fuel in Nevada.

  3. Great on TVA. Bad on Slashdot by gavron · · Score: 3, Insightful

    Good job TVA finally bringing another nuclear reactor online. It's clean, it's safe, and it's advanced.

    Shame on slashdot "editor" BeauHD for adding in the unrelated story about renewable energy overtaking natural gas.
    DID YOU BOTHER TO READ THE SUBMITTED ARTICLE???

    Seriously nice article today about Sourceforge and Slashdot Media all improving must have missed that there are people running the show who can't read.

    The "ironic" thing is a huge amount of it is completely unusable as fuel due to either being not very radioactive or being very active with far too short a life to be used as fuel.

    I'm no expert

    You don't have to be but at least average level of general knowledge that you'd get out of reading one Reader's Digest article would kind of help before posting. The Harford web site has a bit about waste and how they make MOX fuel from some of the waste that may get you up to speed instead of pretending that nuclear waste does not exist and that it's all potential fuel.

  5. Re:"US reactor" What exactly does that mean? by rahvin112 · · Score: 4, Insightful

    It's not NIMBY that stops nukes. It's an electricity price of 14 cents/kwh and that's with the government providing free insurance. Gas can do electricity at less than half that, wind is at 4cents and solar will be cheaper than gas by 2020. Why would you build a power plant that produces power at 2-4 times the price of other sources? Because the only ones that are building these new nukes are the ones that are forcing their rate payers to pick up the cost.

    Without a public utilities commission that's willing to bend their rate payers over and fuck them good and dry, a nuke isn't even feasible. And it's astonishing that there are two states willing to let their utility companies fuck their residents six ways to Sunday. If I was a rate payer in Georgia I'd be fucking livid that I'm being committed to paying 2 times the price for power for the remainder of my life unless I move.
