Who better to know when a nuclear situation is real bad, then those who dealt with Chernobyl.  Russia, back then part of the now extinct Soviet Union when the Chernobyl disaster happened, says Japan is in trouble.

Russian Prime Minister Vladimir Putin says the situation at Fukushima Daiichi is showing no signs of improvement. Russian President Dmitry Medvedev says the situation is still out of control.

From the very beginning of the nuclear disaster in Japan, Russian nuclear engineers have warned that the type of design used at Fukushima Daiichi (by the way, designed by General Electric) is dangerous if damaged in a natural disaster. Basically it can not be saved.
