Decommissioning San Onofre Nuclear Plant May Take Decades 266

gkndivebum writes "Southern California Edison has elected to decommission the San Onofre nuclear plant after a failed effort to upgrade the steam generation system. 'Nuclear economics' is the reason stated for the proposed decommissioning. Other utilities operating nuclear power plants in the US likely face similar decisions when it comes to weighing the costs of upgrading older facilities. Allowing the reactors to remain in 'safe storage' for a period of up to 60 years will allow for radioactive decay and lower radiation exposure for the workers performing the demolition."

    I have knowledge of this matter and I know it's crap. This is about negotiating with a supplier and throwing a tantrum. They have decided to cut off their nose to spite their face.

    (If this sounds like a lot of opinion, it is...but I do have some knowledge on this matter. Once things are final, I'll be happy to share exactly what I know.)

    For the moment, until things change, nuclear power is the only source that provides enough to keep things going without buring stuff and putting it into the air and everywhere. Already nuclear power has saved countless lives as they have safely displaced the amount of coal and gas to burn. Without nuclear power, the net carbon footprint of hybrid cars would be less than barely a net improvement over pure gasoline. Wind, solar, geothermal and others are not able to make it happen.

    Anti-nuke people haven't been paying attention. But just about any way you look at it, nuclear wins. Sure it requires a great deal of care to handle it safely, but we've been doing nuclear in the US for a very long time with a pretty excellent record.

    It disappoints me that greedy business interests are behaving this way. Until we have something better than nuclear, we need to keep nuclear going. (Shut them all down once we've got something better. It's not like I'm in love with the tech, but it's just so much better than burning stuff.)

        In 2012 The German electricity sector increased its coal usage by 4.9 percent over its coal consumption value of 2011.[43] This increase in coal usage was largely due to a power gap in Germany created after the nation shutdown 8 of its 17 nuclear power plants.[44] The shortfall in electricity supply from these 8 power plants, is primarily being filled by building more lignite coal burning power plants.

        Yeah, real good job Germany, thanks for the CO2 increase...dicks.

        hahahaha. Yes they exported something. It definitely wasn't solar and wind though.

        Solar makes up a pathetic 3% of Germany's power in the summer months. Wind is struggling to crack 8% and that's in a country where you can see a wind farm from every other hill. I'm not sure where you're getting your data from but you may want to do this thing called research.

        By the way your wonderful Germany who are abandoning nuclear power opened 2 coal power stations last year, and are planning to open 6 new ones by the end of this year. Yes that's right, your so presumed green country with green power to spare just built 6GW of coal fired glory and plan to open another 12 power plants by 2020. What a shining example of your argument. Germany hasn't even started making serious efforts to shut down nuclear yet but have already increased their coal consumption by 5% [bloomberg.com].

          German physicist here. This is not quite true:

          When Nuclear plants were shut down (drop in 2010-2011), this was mostly compensated for by renewables (and less total production). Also the further decrease in Nuclear power in 2012 was less than the increase of renewables. Yes, also coal increased in 2012, which is mostly attributed to the low cost of emission certificates. Natural gas dropped at the same time, so this is a shift because of changes in cost for different non-renewable energy carries.

            What's hilarious is that as they push for solar, they are also pushing for bans (well, high taxes, 80%ish level) for solar panels imported from China. If China is selling at a loss, then buy them all, and resell them. The problem is that China is not selling at a loss, and the German (and US) makers can't compete. If they are really dumping, don't double the price with taxes, buy them all and put them on every house. Grid-tie them all together, and the home coverage would nearly fill the power needs. Having grown up in the US south, power needs spike as sun efficiency spikes, giving a nice correlation between need and supply.

          IIRC, every one of those coal plants are intended to replace one that is end-of-life or soon to be. And the new plants will be significantly cleaner and more efficient.
          I really wish that Germany hadn't decided to dump nukes and I'm guessing they may change their mind before all the remaining ones are shut.

          One of the problems with phasing out coal is that there's been a subsidy on it since the 70s but that is slated to end by 2018. The major coal producers have stated that they'll shut their mines by then.

        The supplier is not throwing the tantrum. Take my word on that for now.

        The government, the NRC, is doing the right thing in all of this. As I have been exposed to this industry and have been learning what's what and what goes on, I have learned a great respect for at least THIS government agency. Every NRC person has also had direct experience in nuclear technologies. And the thing about people who know and understand the tech, know what can happen when things go wrong and NO amount of bribery or being told to look the other way will cause them to compromise what they know very well is a potentially global disaster event.

        I could go on and on about this. But I do know there are forces opposed to the NRC... to its very existence. It was preciselu the lack of an effective "NRC" in Russia that allowed Chernobyl to happen and even though their regulators weren't quite what the NRC is, the people who caused the disaster had to shop their idea for drill/demonstration around quite a bit before they could find someone stupid enough to take the risks they did.

        For the moment, please understand that you don't understand quite what's going on over there. From what I know, the suppliers are acting properly and appropriately. I've already said too much. But I have to say it's a common problem where business cares more about their bottom line than about other, larger issues. I'm not saying that other parties are not at fault -- the reports are public and I invite you to read through them for further insight. There's plenty of blame to spread around. But this thing about shutting down two plants which are otherwise capable of being repaired and restored to a good, safe and reliable operation? Based on everything I know, it's not merely "nuclear economics." There's a lot more.

        Personally, I believe as the next steps proceed, they might well be forced to change their idea about shutting those down. And the article makes it pretty clear that the "shutting down and packing up" is a far cry from destroying the things and clearing the land.

          The NRC hasn't denied an operating permit in 30 years.

          The last permit denied was only under heavy pressure.
          When the facts came out, everything ended up in court with General Electric & Contractors being charged under RICO statues.

          It wasn't a traditional court case, in that it was a summary jury trial [wikipedia.org].
          GE & others ended up settling because the Judge agreed that their actions were fraudulent and that they engaged in racketeering.

      Which is not to say irrational fear hasn't created nuclear problems -- particularly when it comes to developing long term storage facilities for high level radioactive waste. We also give fossil fuels a break on externalized costs because we're familiar with the and therefore fear them less than we probably ought.

    I thought the point of such extensive containment structures was that they would never be destroyed? Just remove the fuel and any equipment that isn't cemented into the structure and leave the rest. I imagine the general thought-lines behind a lot of nuclear plants was to simply to continue to build new reactors as the old ones had to be decommissioned and continue to use the same generators, transmission equipment & facilities with incremental upgrades over the years. But I think I see why they're going the decommissioning route with this one, even if it was economic to build some new reactors this plant is sandwiched between the Pacific and a major highway. The reactor structures themselves are not more than 400' from the ocean, at least on the face of it this place is another Fukushima under the wrong circumstances.

      The licencing for nuclear reactors in the US, the UK and a few other countries requires that the site be returned to greenfield status after the reactor(s) on site are decommissioned. That means total demolition of the structures including the metre-thick reinforced concrete containment buildings.

      In some cases if the site is to be reused immediately then the reactors are demolished quickly with special handling of the slightly radioactive pressure vessel which has suffered neutron activation. It costs a little bit less to wait a few decades for that radioactivity to decay at which point the demolition can go ahead with no radiation-specific problems. The real problem during demolition in either case with older (1970s vintage) reactors is the presence of asbestos in pipe lagging, tank insulation etc.

That's ~50 GWe-years or ~1,200,000 megatons TNT (thermal). I'm pretty keeping the lights on in the building for a few decades is a bit less than a million megatons of TNT.
