TEPCO: More than 150 billion Bq per day of radioactive isotopes discharged to Pacific Ocean from Fukushima plantPosted by Jim at Saturday, August 30, 2014
26 August 2014 (SimplyInfo) – TEPCO made the startling admission today at a press conference that the plant is leaking 8 billion bequerels per day (8 gigabequerels).
- 5 billion bq of strontium-90
- 2 billion bq of cesium-137
- 1 billion bq of tritium (later corrected to 150 billion bq)
This is the ongoing daily release to the Pacific. These release numbers are also within the realm of what some oceanographers have been warning about since last year, that there was an ongoing and considerable leak to the sea. According to journalist Ryuichi Kino TEPCO said this may be due to failings of some sort within the “glass” wall at the sea front. This is an underground wall made in the soil by injecting a solidifying agent to block water flow.
This daily release would add up to 11,680,000,000,000 = 11 terabequerels over 4 years time in addition to the initial sea releases during the meltdowns. […]
*** Update 2***
It was pointed out last night that the tritium number quoted by TEPCO in the press conference does not match the graph they released to METI. The TEPCO rep gave the verbal reading of 1 billion bq per day. The chart shows 150 billion bq per day of tritium. The other numbers stated by the TEPCO rep seem to match the chart. This change increases the total numbers to 4710 billion bq per month at the current 2014 rate. The bulk of this is tritium. This number change would make one year at the 2014 rate 1,719,150 billion bq for an annual total 1.7 Petabecquerels in a year at this rate. [more]
