Recent radioactive leaks to ocean still happening at Fukushima Daiichi

On page 2 of its Dec. 8, 2011 "Fukushima Daiichi Status Report," the UN's IAEA reports:

"On 4 December TEPCO reported that a leak of water was discovered coming from the evaporative concentration apparatus. Approximately 300 L of water had leaked from the equipment onto the floor of the facility. Due to a crack in the concrete base of the building 150 L of water is estimated to have been able to leak out of the facility and into a drain that exited into the ocean.

Several days later TEPCO released estimates of the amount of radionuclides present in the 150 L that escaped into the ocean. The water is estimated to have contained approximately 2.6 x 10(10) Bq of of Sr-89, Sr-90, Cs-134 and Cs-137. It is worth noting that the annual discharge control target for the Fukushima Daiichi nuclear power station is 2.22 x 10(11) Bq.

This release represents approximately 12% of this target value."

Apparently, IAEA has forgotten that Fukushima Daiichi has caused a catastrophic radioactivity release since March 11, 2011, including releasing tens of thousands of tons of radioactively contaminated water into the ocean over the course of many months. Very likely, Fukushima Daiichi has surpassed its "allowable" or "permissible" radioactivity releases into the ocean over the past 11 months!
