Title: Typhoon Soulik shuts down Jinshan nuclear power plant in Taiwan

Typhoon Soulik stuck Taiwan over the weekend with winds over 100 miles per hour, equivalent to a Category 2 hurricane, so strong in fact that it took out a nuclear reactor twice at the Jinshan Nuclear Power Plant.

Early Saturday morning, the strong winds knocked out emergency systems at the Unit 2 reactor which are designed to reduce the likelihood of lightning directly striking the reactor building, which lead to an automatic shutdown of the reactor. After restarting the reactor, neutron readings in the core began increasing to levels so high they led to another emergency shutdown while repairs were still being carried out on the lightning protection system. […]

The events at Jinshan leave the reader with many questions. Did the typhoon cause the nuclear power plant to suffer a loss of ultimate heat sink, as witnessed at Fukushima Daiichi? Did the emergency systems adequately cool the reactor core while the intake was blocked or clogged, or was the increase in neutron levels due to increased boiling or rapidly decreasing water levels in the reactor?  […]

  • Questions, but no real answers.

    "When water levels fall too much, or become too hot, the water in the reactor begins to boil too fast. This would lead to an increase in the amount of neutrons detected by the monitors. According to experts, the reactor would likely need to lose nearly 15 feet of water for the neutron readings to jump significantly, which would only take some 30 minutes after a reactor shutdown…"

    Apparently, starting up and shutting down a nuclear reactor is kinda tricky and there are many things that can go wrong that could lead to a very bad day.

    They knew this in 1958…

    And in the modern day, well in 1993, they give you a manual.
    So you don't have a bad day…

    And this is the genie that you are trying to contain as you, try to, start up and shut down, your forty year old reactor…

    Neutron poison

    Have a nice day…

    “Taiwan’s Jinshan and Guosheng nuclear power plants are located near a fault line in the Jinshan (金山) area of the Taipei basin, while the Ma-anshan Nuclear Power Plant is less than 2km from the Hengchun fault.

    “Following an assessment by the Central Geological Survey conducted last year, both fault lines are believed to be seismically active.

    “If Taiwan experienced anything like the magnitude 8.9 earthquake that hit Japan, the results could be devastating, Tsai said.

    “The Jinshan Nuclear Power Plant — Taiwan’s first ever nuclear power plant — and the Fukushima Dai-ichi plant were built around the same time and use the same machinery, Tsai said. However, while the Fukushima Dai-ichi plant implemented preventive measures in 2007, power plants in Taiwan are 30 years behind on following quake-resistance standards….

    “By comparison, for more than 30 years, the Jinshan Nuclear Power Plant, in Shihmen District (石門), New Taipei City (新北市), has operated with quake–resistance standards of only 0.3G, Tsai said….”

    Scientist warns of dangers of Taiwan nuclear mishap
    Oct 22, 2012
    “A Japanese nuclear scientist and researcher says that if a nuclear accident occurred at one of northern Taiwan’s nuclear power plants, about 30,000 people would die within a short period of time and up to 7 million people could develop cancer from exposure to the nuclear radiation….
    “Therefore, it is very dangerous to have plants built on unstable strata, especially when operating power plants in Taiwan are considered old and the Fourth Nuclear Power Plant, which is under construction, is being assembled using components from different manufacturers….
    “He also suggested that if Taiwan can increase electricity generation from other power sources, it should close its existing nuclear power plants and halt the construction of the Fourth Nuclear Power Plant.
    “James Kuo (郭國榮), an engineer with 25 years of experience working on nuclear power at General Electric, also participated in the forum. He recently visited the Fourth Nuclear Power Plant and said the nation still lacks professionalism in managing nuclear power, adding that the government often misleads people by saying that nuclear power is a cheap means of generating electricity.
    “’Nuclear power may be cheaper, but operating costs and maintenance are more expensive, so hydroelectric power, wind power and even coal-fired power are all cheaper in the long-term than nuclear power,’ he said….”

    Maybe we should all just pray and all the bad/nasty neutron poison will all go away?

    How many years have they/our controllers gotten away with that song and dance?

    Pay no attention to what we are doing and this is "God's Will"….

    We are all serious trouble and we all need to make more money and consume more crap and yes we need this nuclear electricity because that means we/you can consume more crap and we can give you slaves a job.. while we your controllers make money off all you do!

    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.
    “Chen Yi-pi, director of the council's Department of Nuclear Regulation, said the shutdown of the reactor posed no risk to public safety and there was no release of radiation into the air or water.
