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.

    For 2 units, plus a third already shut down one on the site, this is not too bad a cost. Considering the overall lifetime cost of the plant, including D&D, and even though it shut down early, on a cost per kwh basis, it is a good deal for emission free generation.

    Unfortunately, many will look at the cost and not have a good perspective / basis for comparison.

    Make sure you're not assuming that the $4.4B that somebody is going to get is a bug, not a feature. Some people will get extremely rich from this expenditure and that's a powerful motivator.

  3. Re:of course theres plenty of fucking money by Solandri · · Score: 4, Informative

    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. Edison has said if there's any money left over, it'll be refunded to rate payers.

    I hope my math is correct: Taking numbers from wikipedia, considering only units 2 and 3: both were in operation for a bit more than 29 years and were producing about 1 GW at full power. 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.

    They would have to replace the entire steam generator. That's been done at a lot of plants, in fact the ones at San O were replaced but defective. A few hundred million. But San O is nearing end of life, shale gas is depressing market prices, and politically California is a hostile environment which has its own costs.

    Some of the lost opportunity cost will be borne by the manufacturer of the flawed Steam Generators. But that plant has served well for decades even with an early shutdown.

    Fixating on that one point is an extremely simplistic argument that seeks to ignore the real issues. Nuclear is extremely expensive, and only appears cheap in the US because of massive subsidy.

    It's actually so expensive that the UK couldn't find anyone to build new plants, and the only people who were eventually willing demanded special rates well above the normal unit cost of electricity to be guaranteed for the lifetime of the plant. That's on top of all the other subsidies already on offer.

    It's also worth pointing out that the $4.4bn and 20 year timescale is not the real cost of decommissioning. They are not returning the land to its original state where it could be redeveloped. They are merely encasing the reactors and leaving them to deal with later at additional cost. It also doesn't include the cost of storing material from the decommissioning process that is contaminated for an indefinite period of time. To give you an idea the UK is doing all that to some reactors that were shut down in the early 90s, costing tens of billions of pounds and estimated to take around 80 years for competition (plus indefinite storage of waste from the process, not including spent fuel).

    France's overall price of electricity with tax is lower than Denmark's untaxed price, meanwhile emitting >30% less CO2 per capita with a very similar GDP per capita (to within 5%). If we limit our consideration to electricity, France has ~75% lower emissions per MWh generated than Denmark; and over 80% lower than Germany, the renewable powerhouse of the continent. In fact, they have so much zero-CO2 electricity that they can afford to offset the CO2 emissions from many of their neighbors via transmission. Also keep in mind that France has had this CO2 per kWh value for the better part of two decades because its power mix has always been ~70-80% nuclear and ~15% hydro (the rest being filled in with things like gas, hence why this CO2/kWh number isn't a flat zero).

    The OECD average is so high mostly because of heavy polluters like the US, being the about 1/4 of the population of the entire OECD (not just the high-income bracket), but twice the per capita CO2 emissions of, say, Germany.

    To preemptively dispense with the "we can't build it fast enough" criticism of nuclear, I again present the example of ... France. They initially started construction in 1974 and finished installing >50 reactors, hitting over 70% of generation capacity, within 15 years. So don't believe the renewable industry talking points of "it can't be done on time". It has been done before and it can be done again. If it had the political and popular will, Denmark could hit its CO2-reduction targets for electricity for 2050 some 20 years earlier.

    Funnily enough it is a French-Chinese partnership that is building our new reactors. No British company will touch them. We are handing our basic infrastructure over to companies that have little interest in what is best for the UK and no real stake in what happens to us because they have a guaranteed profit for the lifetime of the plant.

    Subsidy isn't always bad in itself, if it leads us somewhere worth going. Nuclear is on the way out though, we should be looking elsewhere.

    Gas is cheap let's build that. There'll never be aaaaaaaany problem getting gas from the Russians. No sireee. Never mind that local fracking won't supply enough gas.

    Nuclear is only the most expensive option when you stubbornly ignore the externalities.

    The options are:
    1. Renewables (not enough to supply the entire country even using rather optimistic estimates).
    2. Coal which is cheap and astonishingly filthy.
    3. Gas from Russia.
    4. Nuclear.

    The thing is the prices are set by the free market. The free market ignores externalities such as pollution and is purely reactive so it never makes a strategically wise choice. Gas is the cheapest option right now, but is not the wisest choice.

    This is why we have governments. Left to itself, the free market does not make the best decisions.

    I do think that France's build-out of nuclear plants was impressive but your worship of them should be tempered by a couple facts.

    First is that as many as 17 of their 58 plants have been knocked offline or scaled back in a single heatwave because of a shortage of water for cooling thereby needing to import from their neighbors to keep the lights on and costing up to $1300 per megawatt hour.
    The normal peak power prices are usually below $100 per MW-hr.
    A warming climate will lead to this happening more frequently.

    Also, they've been caught dumping nuclear waste in Russia. The lie was that it was sent to be separated and re-enriched to be returned but the truth is that 90% never comes back.
    Right now, it seems that no one who has a significant build-up of nuclear waste is doing a proper job of managing it. Who knows how much has been dumped in backwater nations or into the oceans. And that's with nuclear providing 12% of global electricity.
    What will the waste problem look like if we try to get to 50% in a hurry? Those thorium trolls may be right but it's not likely we'll know for sure before 2030.

    Yeah. That's flat out bullshit.

    Thorium is several orders of magnitude more prevalent in the earth than Uranium. There are a number of fairly large rare-earth mines in the US that are shut down because they're bringing up too much Thorium. This is why China has a lock on rare earths right now. They don't give a shit WHAT they bring up, or what it does. People are cheap and unmonitored dumping is even cheaper.

    Additionally, this is why China's got such a hard-on for LFTR

    Also, the Thorium yearly tailings brought up by just a few US rare earths mines could power the entire energy needs of the country at current consumption levels for several YEARS.

    So there's exactly ZERO "conflict materials" involved. Whoever dreamed this up must pay exactly zero attention to a thing we like to refer to as "reality".

SCE (who was paying large amounts of money every month for all their basic costs including the employees) could never get an answer from the federal regulators on WHEN their applications to re-start the plant would even be processed if they spent the money to replace the pipes (this was NOT normal). When you are paying hundreds of millions of dollars to operate a plant that is producing nothing, and government regulators keep delaying giving you a date when you will even be able to dream of using it IF you make it over the increasing number of hurdles politically-motivated people keep throwing up, at some point you "pull the plug" and cut your losses.

    Nearly all the inflation in the costs of nuclear power has come from regulations and lawsuits. Had it not been for the Ralph Nader style of crusading legal actions designed to kill things (sue anybody making any technology they cannot prove is perfect... and let's not notice that nobody else, like lawyers, are being held to that standard) we would indeed have very cheap and plantiful electricity thanks, in large part, to nuclear power (which has been stuck with ancient tech for many decades because the regulatory/legal environment makes newer safer more-efficient designs uneconomical TO GET CERTIFIED)

The point here is that even though they shutdown after only half it's expected lifetime, they've collected enough funds already to handle it even without the bonds to back it up.

    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.
