Fukushima Daiichi: Highly radioactive water in Unit 2 turbine room may have been in contact with molten fuel rods

The IAEA confirms that contaminated water was found in trenches located close to the turbine buildings of Units 1 to 3.

Dose rates at the surface of  the water in the trenches at 18:30 UTC on 26 March

  • 0.4 mSv/hr for Unit 1
  • Over 1 000 mSv/hr for Unit 2
  • Measurements could not be carried out at Unit 3 because of debris.

According to the IAEA, NISA has suggested that the higher radioactivity of the water in the Unit 2 turbine building is “supposed to be caused by the water, which has been in contact with molten fuel rods for a time and directly released into the turbine building via some, as yet unidentified path. An investigation is underway as to how the water accumulated in the trenches.
