Fukushima Daiichi Nuclear Disaster

  • Background

    What is known about the Fukushima Daiichi Nuclear Disaster is mostly what is below. You should also known that no deaths resulted in the radioactivity. However, three plant workers died from the earthquake and tsunami. This disaster occurred in Ōkuma and Futaba in the Fukushima Prefecture, Japan.
  • Background Pt. 2

    People should care about this because it brings attention to the fact that our nuclear power plants are not able to withstand all natural disasters even thought they are the source for most of the energy in lots of areas, including parts of Arkansas with Nuclear One right outside Russellville on Lake Dardanelle.
  • Commision

    The power plant was commissioned in 1971.
  • Original Problem

    There was an earthquake that caused a tsunami that caused a problem with the cooling rods. The plant's first line defense worked after the earthquake but there were no defense that worked after the tsunami.
  • Written Off

    Four of the six reactors were written off due to damage in the accident.
  • 'Cold Shutdown'

    Power, from grid or backup generators, was available to run the Residual Heat Removal system cooling pumps at eight of the eleven units in the region, and despite some problems they achieved 'cold shutdown' within four days.
  • Stabalization

    The reactors were stable with water addition.
  • Cooled

    The reactors were stable and being cooled with recycled water from the new treatment plant. The basic ongoing process was to prevent release of radioactive materials, mainly water leaked from the units.
