The Blog at:http://gakuranman.com/great-tohoku-earthquake/ includes info about the reactors and pool temperature:March 21st, 2011
02.27 At a press conference with the Ministry of Defence, it was revealed that continued readings taken by helicopter above units 1-6 showed surface temperatures to be below 100 degrees. This is important data that reinforces the possibility that water is landing in the spent fuel pools and cooling the reactors. Unit 1 = 58C, unit 2= 35C, unit 3 = 62C, unit 4 = 42C, unit 5 = 24C and unit 6 =25C. 100 degrees C is the boiling point of water, so temperatures above this are dangerous because it means the water will evaporate and increase the risk of dry fuel rods – a dire situation that would release a lot of radiation. As of 21.30 yesterday evening 3/20/11, the Tokyo Fire Department has resumed dousing unit 3 with water. The plan is to continue for 6 hours.
