It's fairly likely that there is a leak somewhere by now, at least for reactor 2 (where the workers were injured). Radiation levels at trench #2 (contains piping and cables for its reactor) have been measured at 1,000 milliSieverts/hour, which is indicative that the water has been in contact with molten fuel.

He's obviously making blind speculation based on the same information that everyone else has - that there's a lot of very radioactive water in the basement. It could have just as easily been washed down there from the spent fuel pool, they have been spraying water in there constantly, after all.

On March 25, Japanese authorities reported to the IAEA that they had recorded the radiation doses to the thyroids of 66 children living just outside the perimeter of the evacuation zone. These measurements are important because the thyroid tends to accumulate iodine, and radioactive isotopes of iodine make up much of the radiation field being measured far from the reactor site. In addition, children are especially sensitive. The measurements showed no significant deviations from background radiation levels in these children, 14 of whom were infants.
