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. Edison has said if there's any money left over, it'll be refunded to rate payers.
Or goddamn expensive all the while taking a nice steaming dump on the environment.
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.
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.
Pain is merely failure leaving the body
San Onofre is being shut down due to intentionally obstructive Federal and California regulation. After the leaks were found in the new equipment, SCE was wrangling with the Japanese supplier (Mitsubishi) of the bad tubes and trying to put together the plan to replace them and bring the plant online, but CA anti-nuke activists, incluing the luddites at FOE lobbied Democrat Senator Boxer and the Obama administration to make it unworkable. 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)
