Pakistan Builds Nuclear Reactors In Karachi, Sparking Fears of Disaster

schwit1 writes World leaders have fretted for years that terrorists may try to steal one of Pakistan's nuclear bombs and detonate it in a foreign country. But some Karachi residents say the real nuclear nightmare is unfolding here in Pakistan's largest and most volatile city. Of all places to locate a nuclear reactor, they argue, who could possibly make a case for this one — on an earthquake-prone seafront vulnerable to tsunamis and not far from where al-Qaeda militants nearly hijacked a Pakistan navy vessel last fall.

    This must be the most moronic article I've read in a long time.

    3/4 of the way down the text it says the only relevant piece of information: "Minhaj said concerns about the effect of a tsunami are also overblown because the new reactors are being built on a rock ledge about 39 feet above sea level."

    That's 12m above the sea. The tsunami generated by a mag 9.0 earthquake is expected to be between 0.9m and 7m high - so the plant will have 5m margin ABOVE THE WORST CASE.

    Shut up everyone, you've been lied to.

      What actually happened. It was known it could have happened. Nobody gave a fuck. The National Academy of Sciences reported a couple of years ago and said that the problem was ignoring the unlikely scenarios even if it was known that they were possible.

      A tsunami that high is not seen as a possible scenario, likely or unlikely.

      And the "regional instability" thing is just the West not liking anyone else aspiring to approach it. You know what'll stop backward hicks like ISIS? Technical and social advance, not deliberately holding countries back because they're seen by the World Policemen as too primitive to handle whatever.

      There was none. They used the 1960 tsunami in Japan for reference in Fukushima Daiichi (unlike e.g. Onagawa) - which reached a height of 4.5m. This tsunami was caused by the 1960 Chile earthquake on the other side of the planet, across the pacific.

      Yes, baseline nuclear safety in Japan was that crappy - most operators went way beyond the baseline, but at least one didn't.

      A brand new 21st century reactor != Fukushima Daiichi 1960 BWR design. Nor 1950's RBMK design for that matter. Misleading panicky comparisons lead nowhere.

      The nuclear power plants will be ACP1000s. There is half a century of experience between the ACP1000 and the BWR-3/4 used in Fukushima Daiichi. And wouldn't you know it, there have been improvements in the meantime!

      http://www.nucnet.org/all-the-...

      It's a combined passive and active design, it doesn't need power to cool the reactor or the containment, but it has powered cooling systems in addition to the passive ones. -> NOT FUKUSHIMA.
      A backup generator that is above the Tsunami will not be flooded and will not fail because of flooding because it isn't being flooded. -> NOT FUKUSHIMA.
      An emergency stop of a nuclear reacto needs cooling or it will melt the core, which is being provided for in a much more adequate fashion than in Fukushima. -> NOT FUKUSHIMA.
      The ACP1000 is a pressurized reactor in a large dry containment, that can contain a molten core without overpressurizing the containment. It is not a small "pressure supression" containment that has been known since at least 1966 to be unable to contain a molten core - which is a statement made by none other than the vendor, General Electric. -> NOT FUKUSHIMA.

      IUTBATM... I used to be a tsunami modeler.

      There isn't a 1:1 relationship between earthquake magnitude and runup. There are some rules of thumb, but it depends on the faults in the area, if there is risk of landslides, the geometry of the ocean floor, the topography around the power plant, if the risk comes more from local earthquakes or ones on the other side of the ocean basin....

      Hopefully, whoever quoted the numbers for Pakistan has already done the study for the region; I haven't worked too much in that region myself so I don't know numbers offhand. But that 40m you mention was in a very specific location (plus, can't you even cite slashdot? http://science-beta.slashdot.org/story/14/09/27/0225233/underwater-landslide-may-have-doubled-2011-japanese-tsunami )

      For reference, if you hear a number, hopefully they've already done such a study... usually takes one or three people a few months to a few years to do a thorough analysis (plus depending on the model, could be a fair amount of computer time), depending on how important the project is. And if it's below about a 7.5, there is usually no tsunami risk except maybe locally at the source.

      A tsunami that high is not seen as a possible scenario

      Normal waves can reach over 10m in height.
      The reactor is built at only 12m above sea level !!!

    here in the west we can safely laugh at paranoid schizophrenic low iq conspiracy minded douchebags. such losers are everywhere in the world. but a free society with free speech and a free press, the full light of day reveals their delusional rantings, they are ridiculed, and they are safely exiled to the backseat of the short bus and only are compelling to weak minded ignorant halfwits

    but in countries where lies, censorship, prideful ethnic and sectarian denial, etc. dominates, the mental diarrhea of conspiracies has a great power and takes hold in that darkness of no free thought, no free press, no free speech

    You use a lot of fancy numbers but really all you needed to do was look at a map. These reactors are being built in the middle of nowhere (or rather the edge of nowhere since it's on the waterfront). The reactors are not 20 miles from the city centre rather they are actually about 15 miles from the boundary.

    Better still these nice modern reactors with all their modern safety standards and passive safety systems and an inherently safer design are being built in an existing complex next to a set of existing 1970s era reactors. The article even has a picture of the existing plant.

    This is colossal FUD, and they should be welcoming the addition of GenIII reactors so they can eventually transition away from the older ones which actually may be a problem if something seriously goes wrong.
