As Sea Levels Rise, Are Coastal Nuclear Plants Ready? ( 302

mdsolar writes with this National Geographic story about the danger of rising sea levels to low-lying power plants across the country. According to the story: "Just east of the Homestead-Miami Speedway, off Florida's Biscayne Bay, two nuclear reactors churn out enough electricity to power nearly a million homes. The Turkey Point plant is licensed to continue doing so until at least 2032. At some point after that, if you believe the direst government projections, a good part of the low-lying site could be underwater. So could at least 13 other U.S. nuclear plants, as the world's seas continue to rise. Their vulnerability, and that of many others, raises serious questions for the future."

    I am very close to a nuke that is right on the beach on Florida's Treasure Coast. Apparently to shut down a reactor and clean up everything that is contaminated is a process that takes years. This nuke has only one road that runs along the beach and if that road is swamped access to the plant would be by helicopter or boat, weather permitting. And that road frequently has challenges with hurricanes and spring tides as it is. I wonder if any planning is going on in regard to this situation.

      The one one Hutchinson Island? I used to stay there every summer. This article is (surprise!) alarmist. Read carefully, it claims nothing prior to 2032 - and makes references only to things that could happen in the fairly distant future. Compared to the cleanup costs, shoring up a road or building a berm along the Indian River would be pretty cheap.

        In the U.S. we already have entire cities that are below sea level. Fortunately, we have these things called dikes, levees, and cofferdams that we can build when we need to to protect them from actually being underwater (as long as they're properly built and maintained). So even if sea levels do rise as predicted, these plants aren't going to be flooded unless for some bizarre reason we allow them to be flooded.

          Dikes and levees to keep the sea out don't work very well in much of Florida because the underlying bedrock is largely porous limestone. Even if you build a levee the water will just come up through the ground.

          "Conventional sea walls and barriers are not effective here," says Robert Daoust, an ecologist at ARCADIS, a Dutch firm that specializes in engineering solutions to rising seas. "Protecting the city, if it is possible, will require innovative solutions."

        I wish we could switch over to molten salt reactor, They can be easily shut off if needed.

        • That, and build them away from areas prone to natural disasters.

          • How exactly do you propose to cool nuclear plants that aren't built on rivers? There is a reason nuclear power plants are built on moving water (or large pools of water), and it is to allow them to run more efficiently, and not require giant cooling towers.

              • The power plant evaporates the water from the treated sewage from several nearby cities and towns to provide the cooling of the steam that it produces.

                So, evaporating water that could be reused while existing in a desert where there is a significant lack of water...poor planning.

                Sure, that will work everywhere, we should get right on building every nuclear power plant to these specs. We could name them thinkwaitfast plants, then when multiple of them go supercritical in droughts, you can get full credit for your idea of using this cooling method.

      You do realize that if the road gets wiped out while they are trying to decommission the plant ... they'll just build one on a bridge, right? As a Floridian, you're probably aware of just how good Florida's construction crews are at rebuilding after the REGULAR hurricanes and tropical that come pretty much every year ...

      Building roads and bridges is pretty trivial and cheap compared to decommissioning a nuclear power station. And do you know how they brought a lot of the construction materials to the site ... probably by barge actually (thats what happened at the Crystal River plant)

      And decommissioning takes years because its cheaper to wait out certain things than to deal with them while hot. You have to shut the planet down, get it into cold shutdown (no need for active cooling measures), remove the fuel, then wait for all that shit to 'cool down' radioactively enough that it doesn't require robots to work on it. During that time you go tear down all the other crap thats not radioactive and wait for 10 years. Then you come back and get the rest of it with men in some radiation suites that cost about 1000 times less than trying to do it with the robots you'd have had to design, build and use if you tried to do it immediately after shutdown.

      But to answer you actual question.

      Yes, thats all been thought of, before the plant was even built, its all part of the initial environmental studies and is public record if you really want to go digging for it. At one point Looked up all that information for the Crystal River plant, so unless the state was thinking completely differently between the studies for the two stations we're referring to, yes, they've thought of all that already. It might no longer apply (environment changes, hence this discussion), but its been considered.

      The expression is "in my backyard", and this is why a lot of people don't want nuclear power plants in theirs.

    • "On the beach" is the key to the problem. All of Florida is built on sand, so as sea level rises dikes won't be enough to keep the water out, it will simply go under them. You'd need a waterproof basement floor, plus pumps to deal with the inevitable leaks and breaches. You need to turn the whole place into a ship. It is just not going to happen. Florida is doomed, but they're still in denial.

    Yes the sealevels will rise, but they already rise with every hurricane or tides of the moon.
    After Fukushima everyone knows that you need big ass dams, flood walls, protected and working backup generators etc.

    If you build a 10m high floodwall or a 11m high one to also protect against global warming induced sea level rise simply doesn't really matter. If someone hasn't already built said 10-15m high flood wall, it's not global warming that is an issue but the regulatory commission in your country. A much more immediate problem too.

    • Yes, sealevels will rise.

      Of course, we're talking a century-plus before they rise as much as a meter.

      Hardly a problem today. Hardly an issue in a century, really. A meter high floodwall doesn't actually require a century to build (more like a few weeks one summer).

      And if worse comes to worst, well, we add a meter to the floodwall every century (that's about four inches a year for the Amis among us), which is hardly a major undertaking....

    • Learning nuclear lessons is so enjoyable.
    • A floodwall is not a permanent dam. No where on Earth has anyone ever successfully held back the sea permanently. And there are many places where they have tried. There is a big difference between knowing how to build a wall a meter high, and knowing how to build a working sea dam.

      • No where on Earth has anyone ever successfully held back the sea permanently.

    We can move them. Yes, it would suck complete and total ass and be ridiculously expensive and environmentally dangerous, but the sea doesn't rise over night without an Earth quake so in the many many many years while the water is creeping up the shoreline towards the plant ... we can decommission it and move the dangerous bits to higher ground.

    Well, in theory we can ... unfortunately the utterly retarded NIMBY anti-nuke crowd will ensure that instead we'll leave it right where it is cause god fucking forbid some accident might happen ... and instead we'll just let it pollute thousands of square miles of sea and destroy our food stocks instead ... because thats way better than moving some dangerous materials in a controlled and actually very safe method.

    So you either move it and don't tell anyone, so that NIMBY morons don't have a chance to stand in the way of the trucks doing the moving (which makes it way more fucking dangerous!) before you get it to higher ground. Remember these are the same morons who would swallow coal dust and get cancer for sure rather than take the risk that if they hang out at the nuclear plant after a major disaster they might have a slightly higher chance of thyroid cancer ... that can't be proven scientifically anyway.

    Besides ... nuclear reactors are water tight from the start, at ridiculously high pressures, if you get them into a cold shutdown state, you can just leave them under water for centuries without anything actually happening. Put a concrete sarcophagus around it so that nothing can easily damage it and forget about it. By the time it actually starts leaking it will have decayed to something we don't care about nearly as much.

      Just remember, that solar is such a great choice. I mean it's not like we haven't had 17 consecutive days of overcast skies or anything in my neck of the woods here in Canada. The solar panel(30x30ft) nearby has reported a grand total of 1.28kWh of generation for that entire period. Which of course is why we have the second largest nuclear generation plants in the world here.

        You're also in late fall, which is a terrible time for solar generation in northern climates. Where I'm at there's also been a massive solar build-out, but nuclear is such a horrible, evil technology they built new coal plants and new natural gas plants instead. Yep, both natural gas and coal emit radiation in their waste, so thanks ignorant dumbfucks.

    • by dave420 ( 699308 )

      Your feet won't always be dry. It took a massive tragedy for Dutch sea defences to be as good as they are now, and with every rise in sea level, the amount of work required to hold it off grows massively, as the storm surges will get larger, and the frequency of dangerous storms will increase.

      So yeah - looking at the present is not a great way to evaluate the future. Shocker.

      • It's almost like we need a massive tragedy in the nuclear industry to remind us on the importance of keeping the water out. It's a shame I can't recall of one happening.

    • Yes, and to set it into a right perspective, for centuries the land you live on behind the dikes was kept "dry" by: wind power

  • "Estimates for how quickly sea levels could rise vary widely, from up to 4 feet by 2100 to almost 30 feet anywhere between the next two centuries and 2,000 years from now."

    So in the next 90 years, during which time we'll probably build and retire two generations of nuke plants, we might have a whole four feet of sea level rise.

    Please excuse me if I don't take the title seriously.

    • The fashionable retirement plan for nukes is sixty years in mothballs before decommissioning. Soggy mothballs are an issue for these plants.
  • We can build nuclear submarines. Presumably we could build nuclear power reactors that live underwater from the get-go.

  • In the US alone - 130 natural gas, 96 electric, 56 oil and gas, and 4 nuclear facilities at or slightly above sea level. [] Would seem to be a matter of national security !
    • Nukes need a longer planning horizon. First, they are so costly that they need long license periods to hope to break even. Second, they are so radioactive that decommissioning is very dangerous and has to be taken slowly. Yes, we'll lose other coastal infrastructure, but that will shift inland more gracefully than nukes.
  • ...that an energy source that doesn't emit CO2 is being endangered by those that do. So far we've found a lot more "tipping point" mechanisms than buffering mechanisms. Not a good sign.

        Solar power is more polluting, more toxic, less efficient, more destructive of habitat and much less safe than nuclear. Better than coal, sure, but better than coal isn't good enough. Mankind is better off without solar power. It would be much better to focus all of our resources on next gen nuclear power instead of going down the dead end of solar.

    Global warming is a relatively minor issue by itself. The problem is that certain low lying areas already have major issues and global warming makes it much worse. It's not just a rise in sea level - it's also a huge rise in the ground's water table directly caused by the rise in sea level.

    Miami Beach Florida already has issues with tides - certain high tides of the year flood the city, leaving it deep enough for fish to swim into major roads. In some areas they had to raise the roads a full meter above land level so that at least the roads are clear. Of course this leaves the houses, parking lots, businesses all flooded.

    The main problem with Florida is that the water doesn't come from one direction it comes from all six directions. Rivers flow from the other states into Florida, sea water on 3 sides, rain falls down onto it and finally the land itself is porous limestone that sea water seeps into and UP out of the ground. Basically, most of the state of Florida is not solid land, but a sponge. That's why it has sink holes and why floods are so bad. Florida, unlike Holland, does not have a sealing salt/anihydrite layer that blocks water movement.

    For this reason, unlike the Dutch, merely building a huge dike is not enough. As global warming raises the sea level it invades deeper into the center of Florida's porous, limestone ground. What used to be safe relatively dry land, miles from the dangerous shore, is now wet, eroded limestone. Fresh water wells turn into salt water wells, sink holes open up, new springs suddenly appear where there were none before.

    Some of those new springs will be INSIDE the grounds protected by the dikes built around the nuclear power plants.

    In such circumstances, to truly protect a nuclear power plant, you have to put a solid layer of water proof concrete UNDER it, connect that to the water proof 10 ft wall around the nuclear power plant and then arrange for a pumping station to drain out any rain water that falls into the plant area. Good luck with that.

  • The two Dungeness nuclear power stations (Kent, England) are built on the tip of a huge shingle spit. They employ trucks to move shingle from one end of the spit to the other to try and keep it in place like some labour of Sisyphus. That plan was deemed ok before anybody knew about projected sea level rises. Instead of abandoning the site, the owners are optimistic about getting permission to build a third station.
  • At some point after that, if you believe the direst government projections, a good part of the low-lying site could be underwater.

    Sea levels will have risen maybe a foot by the end of the century. Contrary to the magical thinking of some people, a foot is just a foot. The main area it makes a difference is in the height of dikes and other protective structures: a foot in sea level rise may significantly increase the probability that some water goes over such a structure if it is already marginal. That's ea
