Tepco considers evaporating 800,000 m3 of Tritium water to the air
http://fukushima-diary.com/2015/12/tepco-considers-evaporating-800000-m3-of-tritium-water-to-the-air/ On 12/11/2015, Tepco announced the possibility of evaporating Tritium water retained in Fukushima plant area. It was reported in the task force of METI (Minister of Economy, Trade and Industry).
From their report, the estimated volume to be released is 800,000 m3. 400 m3 of Tritium water is expected to be released per day.
The maximum density of Tritium is 4,200,000,000 Bq/m3.
The water is reportedly vaporized at 900 ~ 1,000 ℃, released to the atmosphere at 60m above the ground.
Tepco states the maximum density becomes lower than 5,000 Bq/m3 at 40m area from the releasing point, which is the notice concentration limit.
