Tokyo Electric officials admit they are having trouble controlling temperatures and pressures in the reactors.

The problem is the salty sea water.  While it cools down the reactor, it also increases the pressure in the containment chambers. That’s not good, in fact it’s almost as bad as high temperatures. They are looking into ways to bring large amounts of fresh water to the Fukushima Daiichi facility.

Regarding to the employees sent to the hospital with radiation Beta Burns; the water they were standing in was 10,000 times more radioactive than the normal radioactive water in the reactor containment system.
