Changes to Fukushima Daiichi Plant Status

Freshwater injection is confirmed to continue for Units 1 to 3. The transfer of contaminated water from Unit 2 turbine building to the condenser was started (12 April) and suspended (13 April) to check for any leakage. Temperature at the Unit 1 outlet nozzle shows a decreasing trend continuously for several days now.
