Decommissioning Nuclear Plants Costing Far More Than Expected 288

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.'"

      It's hard to have a proper discussion on this one because there's no cost breakdown given, no reason why decommissioning is so expensive. There's not even any indication if it's just this one plant that is expensive, all plants in the U.S., or all first-generation plants in the world.

      While the $39 million build cost would be far, far greater after adjusting for inflation, making the $608 million decommissioning seem less ridiculous, this still seems much more expensive then it ought to be. Why? Lawyers? Regulations? A poor reactor design that is simply very difficult to dismantle safely?

      Coal is the largest and fastest-growing power source worldwide, and as I understand it, the dirtiest in terms of pollution in general as well as CO2. Wikipedia [wikipedia.org] seems to say that renewables (including, er, wood burning?!) currently have 5% market share in the U.S. (the tables could use some clarifications). In practice, nuclear energy is a necessary ingredient to get CO2 emissions under control. So let's figure out what these huge costs are and then talk about how to reduce them in the future.

        The plants are breaking down. They are used. Decommissioning Maine Yankee (900 MWe) took eight years and cost $500 million. It ran for 25 years. For Humboldt Bay(63 MWe) it is $982.3 million http://www.dra.ca.gov/general.... [ca.gov] it ran for 13 years. Vermont Yankee (620 MWe) is expected to cost $1 billion to decommission http://cleantechnica.com/2014/... [cleantechnica.com] after a run of 42 years. This estimate will likely balloon. There is severe ground contamination at the plant site and perhaps beyond its perimeter as well. Crystal River (860 MWe) ran for 32 years and is estimated to cost $1.18. billion http://www.tampabay.com/news/b... [tampabay.com] 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.

      By the time they decommission a reactor it is usually 30 or 40 years old. By that point everything is worn out. You could save some hardware and infrastructure; but, you would be replacing most of the equipment, including all the expensive bits. You'd basically end up tearing it all out and rebuilding it new. Car analogy: I'm restoring a 40 year old truck. Engine had to be torn down to raw casting and rebuilt with all new parts (only I didn't have to deal with neutron damage or metal embrittlement) The truck chassis and body: Well, I'm tearing everything off the frame and I'm starting from there. It will all get disassembled, cleaned, repaired and painted, then go back through a complete re-assembly process using factory manuals. When I'm done, it'll be a 30-40% new 40 year old truck. If you count my time at typical shop labor rates, it could end up costing almost as much as just going down to the dealer and stroking a check for a brand new one. The new one would probably be safer...

      A lawyer can't make you do anything. I once had a business partner who froze like a deer in headlights whenever our lawyer opened his mouth. As I said to him, the lawyer's job is to advise you of the trouble you might get into; but there's always *something* to be concerned about; it's *your* job to make a decision and shoulder the consequences. Business people choose which risks to take, and lawyers help them figure out what those risks are, simple as that. If your plans go kaplooie, it's your fault; possibly for hiring the wrong lawyer, or possibly hiring the right lawyer but letting him run your business for you.

      This "it's all the lawyer's fault" business is childish baloney. It's not lawyers that keep owners from continuing to use these old reactors, it's the fact that these reactors are old and obsolete. It's not lawyers that made decommissioning the plants more expensive than projected, it's that nobody had ever done such a thing when the costs were estimated, and everyone chose a best case scenario in their plans because they wanted to see the things built. That's a *business* mistake, and an engineering mistake, but unless the lawyer was telling them they'd be able to cart their waste off to the town dump it's not a *legal* mistake.

        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:
            https://www.youtube.com/watch?... [youtube.com]

    • The data I've seen suggests that Thorium reactors are still somewhat experimental. That's ok, everything is experimental before it becomes real; but it seems wise to try them out on a small scale before switching fully to Thorium. Fortunately, China is doing exactly that, so we should have a lot deeper understanding of Thorium soon.

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]"

    Of course it takes longer to decommission than to build. When it was built all the materials were essentially safe, non-toxic materials where handling is easy, well-understood, and well supported by standard systems, factories and the like. When it is torn down much of the material is unsafe or toxic to some degree, some is extremely unsafe and toxic, and all of it must be dealt with in situ using systems that are not commonly used elsewhere. Handling toxic material safely takes more time than handling safe materials. The extended time leads naturally to extended cost. As wise people have observed, time is money.

If you suspect a man, don't employ him.
