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.

Not a bad deal

[Mr D from 63]

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.

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).

Seriously. Listen to the linked audio. Thorium or whatnot will be more difficult to obtain and maintain than Uranium - creating new classes of super-expensive "conflict minerals" - rapidly exhausting sources as expensive, horrible wars are fought.

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".

Nobody accounted for regulatory costs

[Anonymous Coward]

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)
