The water level in the Unit 2 and 3 tunnels is 28 cm and 24 cm from the top of the tunnel and rising. They are considering using the basements of a couple of buildings for additional storage. Earlier in the week Fukushima experienced a typhoon, so additional water entered into the damaged buildings. The water processing facility is still a couple of weeks away from being ready. Groundwater surveillances have been increased to determine whether any of the buildings are leaking radioactive water.
A heat exchanger has been installed for cooling the Unit 2 spent fuel pool. The temperature of the pool is down to 58°C. The lower temperature will reduce the humidity in the Unit 2 reactor which needed to be lowered to facilitate working within the building.
It was estimated that cleaning up Fukushima Daiichi and the surrounding area would cost $250 billion over 10 years. The estimate included $54 billion for buying all the land within 12.4 miles of the plant. This indicates the radioactive isotopes released from the plant have contaminated the land and people living in the area would receive levels of radiation in excess of allowable limits
