Fukushima 1 Nuclear Accident Day 10: Sunday, 20 March 2011

03:00
Restored emergency power to the spent fuel pond cooling systems for units 5 and 6 have brought the unit 5 pond temperature down from 68.8 °C to 43.1 °C and the unit 6 pond temperature down from 67.5 °C to 52 °C as of 03:00 JST.

"The Nuclear and Industrial Safety Agency said there is some positive progress and engineers at the end may not need to open valves inside the container vessel of the No. 3 reactor to alleviate pressure that is building up", while they were initially planning this action. Such a move, if forced, would release more radioactive steam.
09:00
Spent fuel pond water temperature dropped to 36.1 °C at Unit 5 and 36.6 °C at Unit 6.
