Decommissioning Nuclear Plants Costing Far More Than Expected

Lasrick writes: "This article takes a look at cost estimates of nuclear power plant decommissioning from the 1980s, and how widely inaccurate they turned out to be. This is a pretty fascinating look at past articles in the Bulletin of the Atomic Scientists that consistently downplayed the costs of decommissioning, for example: 'The Yankee Nuclear Power Station in Rowe, Massachusetts, took 15 years to decommission—or five times longer than was needed to build it. And decommissioning the plant—constructed early in the 1960s for $39 million—cost $608 million. The plant's spent fuel rods are still stored in a facility on-site, because there is no permanent disposal repository to put them in. To monitor them and make sure the material does not fall into the hands of terrorists or spill into the nearby river costs $8 million per year.'"

    This is a solid fuel water cooled reactor problem. Ok, that's 95% of current reactors, but there are many alternatives.
    We must see all water cooled, solid fuel reactors as a legacy.
    LFTR Molten salt reactors running primarily on Thorium could take 3% of it's fuel as spent nuclear fuel from water cooled reactors are fission that completely (99%). There is so much nuclear energy on accumulated depleted uranium and spent nuclear fuel to produce a trillion dollars worth of electricity.
    Remember, it's not nuclear waste, its mostly unburned fuel, a result of extremely inefficient solid fuel reactors cooled by water.

      The Slashdot frenzy for Thorium reactors which do not exist anywhere in the world, except as a hypothetical, is constantly astounding. It's nigh-equivalent to denying the round Earth, evolution, or global warming. Sure, they may exist "soon" if your definition of "soon" is on the order of a century. India has had a 3-stage plan for Thorium reactors since the 1950's and they're currently about halfway through that plan, according to its handlers:

      "According to replies given in Q&A in the Indian Parliament on two separate occasions, 19 August 2010 and 21 March 2012, large scale thorium deployment is only to be expected “3 – 4 decades after the commercial operation of fast breeder reactors with short doubling time”.[66][31] Full exploitation of India’s domestic thorium reserves will likely not occur until after the year 2050.[67]"

      The true reasons for the MSR project at ORNL (Oak Ridge National Labs) being cancelled look more like this:

      It was never a mainstream project. Dr. Alvin Weinberg got funding for his idea due to ORNL being the sole responder to USAF demand for a nuclear powered bomber in the 60s. They managed to do their thing kind of under the radar, I believe other nuclear guys thought they would never be successful, so when he showed he was (MSRE 5MW test reactor ran for 22000 hrs) and he asked for real money to do the whole thing, then he got shot down.

      Only ORNL was researching into Thorium, all other nuclear labs were working on fast uranium/plutonium breeders.
      The thing about other reactors being better for Plutonium production is a very big misconception that conflates reactor grade plutonium and weapons grade plutonium. Weapons grade plutonium has always been produced by irradiating lots of U-238 with a fairly small dose of neutrons, to avoid double irradiation of U-238 atoms (leading to Pu-240). Conceivably weapons grade plutonium can even be produced by placing a blanket of U-238 around any existing reactor (catching only neutron losses). Any reactor will do. But today it's way easier to obtain highly enriched U-235 instead. Reactor grade plutonium = premature detonation or nuclear artifacts becoming duds in storage, both a huge problem. Too much Pu-240 and Pu-241. Pu-239 does simple alpha decays, while Pu-240 has spontaneous fission probability.

      Plus the main fast breeder research site was in Southern California, right where Richard Nixon was from (exactly when the ORNL Thorium project was cancelled and officially buried). There is a very complete video about this on youtube:

    Nuclear power has always been a pipe dream of some sort. Once it was "power so cheap we won't even bother to meter it". The fact of the matter is cleaning up a mixed bag of uranium, plutonium, and whatever isotopes is a complicated matter that costs a shitload of money. The pie-in-the-sky promoters of nuclear energy have always underplayed the costs. No reactor has ever been built under budget. No clean-up has been under budget. It is just incredibly expensive to build, operate, and decommission a nuke plant. The promoters just don't want to deal with realistic figures. And, then there is the cost of disposing of the spent fuel....

    Hoover Dam cost $49m to build. Today, the price tag would be over $10b. Stuff gets more expensive over the years. Today the power plant produces 4.2TWh per annum. At $100/MWh, that's $420,000,000 of power per year. Kind of significant ROI.

    The bottom line is, long term projects like nuclear or hydro will always cost massively more in the future than today simply because of inflation. This is another reason why these are strategic assets to invest in.

    As for decommissioning of nuclear power? It sits there for a few decades with a few guards on duty. Then you haul it away and melt it down and make new steel out of it.

    Now, how much would it cost to decommission our coal and oil facilities?

    "physics" does not make it expensive, mis-guided political activists, their lawyers, and the "soccer-moms" they scare make it expensive.

    Nuclear power is actually remarkably simple and straight-forward. If you want extreme safety and are willing to sacrifice some efficiency, then you can even build a nuclear generator with no moving parts and that is incapable of melting down (ever hear of an RTG? the Voyager probes? ring any bells?). As for waste disposal: nuclear fuel is remarkably dense and as a result, it does not take much space to store it. You could store all the spent fuel rods the US has ever generated and all the rods we'll likely use over the next century in an area the size of a football field. Nothing says you have to store that in salt mines - you sould store it in sealed casks above ground with continual monitoring for leaks and automated systems to transfer the waste of any leaking cask to a new one (perhaps less hands-off than the bury-and-forget model, but still not a major burden). Of course the very radioactivity of "spent" fuel that makes so many ignorant people afraid of it is the plain evidence that it should not be disposed of at all; it's still FULL of usable energy that can be obtained by re-processing the rods. If you actually consume all the energy available (by use, re-processing, use, re-processing, etc), then the "spent" fuel would no longer be highly radioactive (duh).

    If we used only a small portion of the energy available in another source and then fussed about how to store all the "spent" material, we'd be nuts. Nobody could operate a car if all the "spent" fuel had to be captured and stored for a thousand years to "save the planet". If we treated all the toxic effects of ANY other power source with the same level of paranoia, we'd all move back into caves and give-up on that crazy new-fangled "fire" stuff that some people recklessly use to stay warm and cook food. Wanna store all the tailings of a rare-earth minerals mine as a "cost" of operating wind farm?

    As for safety: Nobody has ever died from a nuclear power accident in the U.S. The same cannot be said for any other industrial-scale power source - people in the petroleum industry die every year, same for coal - we've even had people killed in wind farms. Fatalities at Chernobyl simply cannot be used as a mark against US nuclear - no plant like Chernobyl would have ever been built in the U.S.

Crystal River (860 MWe) ran for 32 years and is estimated to cost $1.18. billion http://www.tampabay.com/news/b... This is low ball because sea level rise will make the site vulnerable to storm surge and letting it sit for 60 years will not be an option. The more contamination, the greater the decommissioning cost. Extending licenses for power plants may double or triple the decommissioning cost owing to larger contamination and for sea level plants, a rush to decommission as the storm surge risk becomes higher.
