Kyodo News, July 16, 2013: Human error causes Taiwan’s nuclear plant shutdown [...] Chai Fu-feng, a spokesman of Taiwan Power Co. (Taipower), told Kyodo News that the Unit 2 reactor of the Chinshan nuclear power station in New Taipei City was automatically shut down when instruments detected too much water in the reactor pressure vessel. [...] a plant worker switched off a draining valve to control the heat in the reactor [...] Panicking, he added water to the reactor to keep the water level up, but he added too much water too fast, which eventually caused the reactor to automatically scram, he said. [...]

World Nuclear News, July 16, 2013: [...] winds above 117 kilometres per hour threatened transmission systems. [...] the height of the storm saw damage to Chinshan 2′s main transformer, which triggered an automatic shutdown. A few hours later seawater overran the cooling water intake bringing in plant debris that clogged the debris screen. Later inspection confirmed lightning damage to the main transformer, as well as storm damage to the switchyard insulator and 350 kV overhead lines. [...]

    I think there were 2 different units shut down. Unit #2 is still shut down and may be the one with excess neutrons:

    Looks like both Units 1 and 2 were shut down.

    Human error causes Taiwan's nuclear plant shutdown
    July 16, 2013
    “Taiwan's No. 1 nuclear power plant located in the densely populated north of the island was automatically shut down on Saturday due to human error, the operator of the facility said Tuesday.
    “Chai Fu-feng, a spokesman of Taiwan Power Co. (Taipower), told Kyodo News that the Unit 2 reactor of the Chinshan nuclear power station in New Taipei City was automatically shut down when instruments detected too much water in the reactor pressure vessel.
    “Power shedding was activated as part of the procedure to protect the reactor when Typhoon Soulik lashed northern Taiwan on Saturday, he said.
    “However, when a plant worker switched off a draining valve to control the heat in the reactor, the outcome did not turn out to be what he had expected, he said.
    “Panicking, he added water to the reactor to keep the water level up, but he added too much water too fast, which eventually caused the reactor to automatically scram, he said.
    “After fixing all the problems, Taipower submitted a report to Taiwan's Atomic Energy Council on Monday for review in accordance with regulations.

    I remember less than a year ago the Byron Nuclear Plant had a reactor SCRAM caused by lightning strike too. During hurricane Sandy the Oyster Creek Nuclear Plant had a SCRAM too, I believe caused by a down powerline. As for the water intake pumps, Arnie Gunderson pointed out sometime ago that these pumps that can't work when submerged, they are a weak link to nuclear power plants during flooding. With our current weather forecasting ability, we have known about these storms before they happen. Why are these nuclear plants taking these higher risks by not shutting down the reactors before the storms? More radiation is released during a SCRAM than during a normal shutdown too! Nuclear power is CrAzY and the risk vs. reward SUCKS!

    >>>Why are these nuclear plants taking these higher risks by not shutting down the reactors before the storms?

    The love of money is A root of all evils. Not the only root, but its always there, and features very prominently in an industry that puts money before life.

  • Lots of risks, not much reward, if any.. it is the same story, over and over, with all things nuclear. We might as well load these reactors on bombers and fly them around, for all the good they do.

    I say give that man a metal for causing the shutdown. Need more people like him all over the world shutting down these death makers.
