And the latest from TEPCO on April 11, 2013 in the email notice to the press No.35:
Transfer of waste water from the in-the-ground water storage pond No.3 to the pond No.6 started at 2PM on April 11, but a leak was found at the flange of the pipe of the transfer pump at 2:03PM, so we stopped the pump.
The leak stopped when the pump was stopped. The leaked water was soaked into the soil.
We will disassemble the flange to investigate the leak that occurred during the transfer of waste water from the pond No.3 to the pond No.6.
We will also start removing the soil that covers the top part of the water storage pond where the leaked water may have dripped.
The water contains 290,000 Bq/cm3 of all beta (mostly strontium), and 22 liters of this water leaked, as TEPCO's email notice No.36 confirms. That would be 6.38 billion becquerels of all beta (290,000 x 1000 x 22). Who is going to disassemble the flange and remove the dirt? TEPCO's president? One of Mr. Abe's ministers who frequent the plant for photo-ops?
They are having another press conference starting at any moment now (scheduled to start at 6PM local time).
Flange that leaked, from TEPCO's photos and videos library 4/11/2013:
TEPCO's Ono says the pump was never tested with running water. (UPDATE 4/14/2013) Ono in fact said during the press conference that the company sort of tested, by making sure the bolts were tightened to the specification, and that, by definition, was safety testing.
