Today TEPCO has received the ordering document "Steps to be taken regarding 
the leak of water including radioactive material at the water desalination 
of Fukushima Daiichi Nuclear Power Plant (order)" from the Nuclear and 
Industrial Safety Agency (NISA) of the Ministry of Economy, Trade and 
Industry (METI), regarding the confirmation of leak of water including 
radioactive material at the water desalination (evaporative concentration 
apparatus) of Fukushima Daiichi Nuclear Power Plant.

We will act without delay according to this order and report the results 
to NISA.

 "Steps to be taken regarding the leak of water including radioactive 
 material at the water desalination of Fukushima Daiichi Nuclear Power 
 Plant (order)" 
                                                (No.1 NISA 2011/12/05)
  
  NISA has been reported from you (TEPCO) on December 4 2011 that you have 
  confirmed leak of water including radioactive material at the evaporative 
  concentration apparatus of Fukushima Daiichi Nuclear Power Plant.
  Regarding the fact that water including radioactive material has leaked 
  outside of the building, we require you to act as written below and 
  report to NISA every completed step without delay.

  1.Investigate the cause of this incident and establish plans to prevent 
    future similar incidents.
  2.Since there was leakage also from the barrage that was supposed to 
    prevent leakage expanding further from the evaporative concentration 
    apparatus, immediately confirm the soundness of other barrages and 
    reinforce them if necessary, and establish future plans to prevent 
    leakage from the barrage, such as strengthening patrols or installing 
    leakage detectors. 
  3.Confirm the range and amount of the leakage, including whether or not 
    there was any to the ocean, and evaluate the impact of the radioactive 
    materials to the surroundings.
