San Onofre Nuclear Power Plant Dismantling Will Cost $4.4 Billion, Take 20 Years

mdsolar writes with news about the closing of the San Onofre nuclear plant. Dismantling the San Onofre nuclear power plant in Southern California will take two decades and cost $4.4 billion. Southern California Edison on Friday released a road map that calls for decommissioning the twin-reactor plant and restoring the property over two decades, beginning in 2016. U-T San Diego says it could be the most expensive decommissioning in the 70-year history of the nuclear power industry. But Edison CEO Ted Craver says there's already enough money to pay for it. Edison shut down the plant in 2012 after extensive damage was found to tubes carrying radioactive water. It was closed for good last year.

    The money for the reactor's decommissioning comes from surcharges to electrical rates collected while the plant was in operation. This money was earmarked specifically for reactor decommissioning costs, and placed into a trust fund which currently contains about $2.7 billion (the $4.4 billion cost will be accrued over several decades, so interest on the $2.7 billion makes them more equal than the raw numbers suggest). That there is sufficient money despite the reactor shutting down only halfway through its expected lifetime means there's a huge margin for error in these nuclear decommissioning funds.

Ignoring any production time lost for maintenance (my guess is they would run with a duty cycle of 80-90%), the total amount of produced kWh would be: 29 years * 365 days/year * 24 hours/day * 2 GW = 5e14 Wh = 5e11 kWh. The price for the decommissioning would thus come down to around 4.4e9 $ / 5e11 kWh = 0.0086 $/kWh, so let's round it up to 1 cent per kWh. Average price for electricity in the US seems to be around 0.10 $/kW, so the cost for the decommissioning seems acceptable, though not negligible.

No problem, geothermal/hydro/whatever! (Triple the cost.) And how do you site so much geothermal or hydro capacity, considering most places either don't have them (geothermal) or are already maxed out (hydro). Also hydro can't produce for one week at a crack, most dams are limited to 6-8 hours at full power. So gas peaker backup? (Quadruple the cost?) See these are the problems when you intend to build a grid with a reliability higher than that of some 3rd world country.
      2. A demonstration of one ideal week is a sham. You need to look at worst case scenarios, not best case. And those are the things that dictate capital expenses, as you pay for installed capacity and only earn for delivered energy. If power plants (either fossil or hydro or geothermal) don't operate a considerable amount of their lifetimes, they'll either never ROI (i.e. go bankrupt or just won't get built at all) or they'll have to be operated at a loss to the utility, which will again just make electricity more expensive.
      3. Transmission grids are only to temporarily even out partial outages of a small portion of generation capacity or sell of some small portion of excess capacity in one locality to another. What intermittent sources require is lots of high-capacity bi-directional transmission, i.e. tens of GW across long distances.

Are we supposed another 60 GW of solar just to cover this eventuality? And during those times that it's not needed, what will we do with it? Who's gonna pay for this?

You have to do something. And we know what countries like Germany are doing: firing coal at record rates, increasing, not decreasing their CO2 emissions.
      6. And all of this before we get into issues such as sub-synchronous resonance on the electric grid due to tens of thousands of turbines.

      I'd also recommend, if you understand German, a talk by Hans Werner Sinn about the upcoming failings of the German Energiewende: http://youtu.be/m2eVYWVLtwE?t=...

    Inflation makes it impossible from a practical perspective to pay up front. 4.4 billion 30 years ago would never have happened, and would turn into ridiculously large amounts of money today, and as such, ridiculous over kill.

So, you are correct, if you factor in those types of things, no source is emission free.

    France regularly has to import electricity during the summer and winter because it doesn't have enough capacity, often due to plants being forced offline for various reasons. Essentially they use the rest of Europe as variable capacity, and Germany in particular makes a lot of money from that.

    I don't know how you can make any claims about the cost of French electricity with a straight face. Clearly the price is heavily subsidized, with the subsidy going to the nuclear energy industry. Like all commercial nuclear power they don't have any real insurance, the government covers it, and their industry has benefited from massive government assistance over the years. The French decided to build a domestic nuclear power industry and did so, but that doesn't mean any other country can do the same unless they ware willing to spend the same amount on it. That's a big ask these days, now the reality of nuclear power is understood much better.

    Anyone want to clarify what the problem with thorium is?

    Existing stakeholders have put a lot into Uranium and were willing to lobby the Clinton era government to get a Thorium research reactor shut down and hound the head of that project out of the nuclear industry. He dared to suggest that a Thorium reactor would be safer which implied that existing reactors were not safe enough. While that was years ago it seems to be the end of the matter as far as the USA goes.

    India was starting mostly from a clean slate and Uranium exports to them were blocked for decades (while they were not blocked to Iraq in the 1980s - funny really), so they had some incentive to use Thorium (plus that's how they got material for their bomb in an unexpected way). Now a lot of places are trying to sell them cheap Uranium so it's uncertain whether they will continue to develop new Thorium based designs, some that look like they can also take expended Uranium fuel rods and use them without any need for reprocessing.
    China seems to be ready to try anything they can get.

    And this stuff should be more precious than gold, oz for oz. Unfortunately nobody likes working with molten liquid sodium, even the machoest of machoest chemical workers, they balk at the idea of a liquid sodium jet spraying them from a heat exchanger leak. Maintenance is a bitch. But if the best minds, the kinds that are pitted at coming up with the latest ipods and gagdgets, focused on this topic, they could probably come up with some good solution, and the profits to reap are tremendous, as soon as the price of gas hits $5/gal, while the whole thing did not even deserve attention at gas prices of $1/gal out of which most of it back then was taxes, and the crude price was $0.15-0.20/gal, and nowadays it's more like $2-2.50/gal. That's a 10x increase even today, and such 10x things make or break profitability. Helium cooling instead of sodium cooling is not a panacea either, because of lower heat transfer coefficient, and also moderation (so you could use Argon not to moderate, as all Th and U238 reactors require fast neutrons, unlike the U235 ones, the U238 enrichment waste from U235 enrichment is just as precious as the Th waste from mines, or even the U235.), so because of the lower heat transfer and heat carrying capacity you need lots of contact surface area, along the lines of a car radiator shape, and fast gas velocities, and any kind of pluggage in the uniform gas velocity distribution can create local overheating, and local nuclear meltdown, unlike with car radiators, and unlike with liquid sodium immersion where the high heat transfer ability of the liquid molten metal ensures that no voids are left, and no great velocity with highly uniform distribution is required. Molten lead/bismuth eutectic is a bit better than sodium in the getting sprayed all over the place goes, but it melts at higher temperature, and as the Russian submarine experiments prove it, it's a bitch to get flowing and unstuck with an external torch when it freezes. So sodium it is, it's very unsafe if it leaks, but it melts easier, and alloyed as NaK it competes with Hg for low melting point. Maybe the Japs will come up with the nuclear robots, as they are smart, and the most energy dependent on such a technology. Perhaps that's why they had a Fukushima accident, so that, unlike the Germans, which killed their nuclear program in face of a helium gas cooled stacked pyramid of nuclear fuel balls shifting unsafely, the Japanese are supposed to hold the other cheek instead, and bounce back by coming up with robots, that instead of being human companions that looks like anime teenie weenie characters with panties and huge tits and blow out of the water any human female's tongue and lips at the ability to give a sensual blow job, they could focus on something more important to the welfare of their people, and national security, such as designing remote control robots, that piss on being sprayed by liquid sodium, or taking a high total body radiation dose, in fact they get off on bathing in that shit, and keep score on how much total body irradiation their hafnium free zirconium limbs took that day.

    It's possible you meant Thallium 208 (Historic Name: Thorium C, Half-Life: 3 minutes)?

    There are two observationally stable byproducts at Tl203 and Tl205. The most stable of the remaining isotopes has a half-life of just under 4 years. Most of the rest are measured in hours, seconds and in some cases, milliseconds. So yes, it's very "hot". But it's extremely short-lived.

    Thanks for pointing that out and also much appreciated about not being a dick about it.

    I checked my notes at home and they were about Thallium 208. I agree, I want to learn more so I can have a reasoned and measured response. Unfortunately I see the nuclear mod trolls are out in force again.

    I have nothing against this type of reactor technology, in principle however I'd like to know more about it's spent fuel byproducts and operational effluents. It is important to understand that if the halflife is three minutes and it's an energetic emmiter, how many daughter product iterations does it got through before it becomes stable an what is the rate of decay? That in itself may pose an even greater threat *because* if it is continually changing just how many micro-nutrient analogues does it present to biology? I'm not going to pretend I know the answer because I am still learning myself, however at least I know that's a question to ask. Another question about a Thorium fuel cycle to uncover is are we just making a new problem. Regardless of that, we still have problems with the Uranium based cycle and they all lead back to the same thing.

    The bottom line is that because this whole debate is so polarized, no one talks sense about it anymore. The irony is that if you took a rational look at both sides of the debate you would see that what the anti- and pro- nuclear lobby need is exactly the same thing.

    So let's get to the bottom of this whole pro- anti- nuclear bullshit right here.

    Pro-Nuclears: want to have new reactor technology developed and deployed, old reactors desposed of responsibly. Is that a fair call?

    Anti-nuclear: wants no Nuclear industry at all, but if it has to be there clean it up an make it safer. Is that a fair call?

    Answer: What both parties need to have *both* of their goals satisfied is a Geologically Stable Fuel Containment Facility. The original DOE, defense in depth spec. In every country that has Nuclear reactors, in granite to deal with the ground water issues and avoid relying on containment technology.

In following the same path I've been fortunate have access to people. The thing is you have to learn not just about the reactor technology, but enrichment, mining, reactor disposal, spent fuel containment, lots of radioisotopes - their energetic properties, toxicity, the micro-nutrients they analogue that causes bio-accumulation in the food chain and what cancers they cause in humans. Then there is the poltics, funding, legislative constructs like Price-Anderson, funding arrangements in the 2005 Energy Bill (for example), it's PR machine, reports into accidents (like Chernobyl, Fukushima), NRC and regulatory operating principles, understanding their reports and the consequences of the metric they report. The effect of the IAEA interdiction orders on WHO organization publications on radiological findings. And still there is more.
