What does he mean by "Chinese syndrome"?
Because at the base, it is a science fiction theory without scientific foundation (melting of the reactor, and flow of radioactive fluids to the center of the earth ...).

It was just the overly sensationalist term that bothered me.
I hope this accident will end well ... in the event of the reactor core melting there would be a risk of weakening the lower enclosure of the latter, with in the worst case possible contamination of the water table water.

It not smell very good (at all) Japan side or risk nuclear alert !!!

It's much worse than I thought, a Japanese Chernobyl is it going ???
And before the collapse we already had this:

Given the urgency, japan he will use as the Russian liquidators did in 1986?
The roof of the Fukushima nuclear reactor collapsed
MINUTE BY MINUTE - A white cloud rises above the plant, where an explosion occurred. The Japanese televisions are advising residents to caulk.
9h25: The roof and walls of the Fukushima reactor building collapsed, said the local prefecture.
The Japanese televisions are advising residents to packing, in an area "larger than 10 km evacuation zone." Experts and journalists of the chain also advise people on the outside to protect the respiratory tract with a wet towel and cover the maximum to avoid direct skin contact with air.
9h00: An explosion was heard at the Fukushima nuclear power plant No. 1, in north-eastern Japan, and a white cloud rises above the site. Several employees were injured by the blast.

Fukushima nuclear reactor: NHK advises to caulk home
TOKYO - Public television NHK advised the Japanese to seal in their homes and close their windows in a perimeter "wider than the 10 km of evacuated area" on Saturday after the explosion in a reactor at the Fukushima nuclear power plant No. 1.
Experts and journalists of the chain also advised the people outside to protect the respiratory tract with a wet towel and cover the maximum to avoid direct skin contact with air.
An explosion occurred between 15H30 and 16H00 in reactor No. 1 of the nuclear plant Fukushima No. 1, located 250 km north of Tokyo, a day after 8,9 magnitude earthquake that devastated the northeast from Japan.

It's much worse than I thought, a Japanese Chernobyl is it going ???
And before the collapse we already had this:
A radioactivity level thousand times higher than normal
March 12, 2011
"Simple precautionary principle", had said yesterday afternoon, authorities, conducting the evacuation of some residents 6.000 in a three km radius zone around nuclear power plants in Fukushima (northeast). But nine hours after the first shock, the pressure is raised a notch when the Prime Minister asked residents to evacuate within 10 kilometers of the Fukushima number one plant. And this because of a radiation leak. Previously, a level of radioactivity thousand times higher than normal had been detected in the control room of reactor numéro1 Central. Outside, the radioactivity level was eight times higher than normal and then presented no health hazard, according to publiqueNHK television. Located 250 kilometers north of Tokyo, the central part supplies the capital.
Eleven reactors at standstill
Among 55 nuclear reactors operating in Japan 17sites, eleven were automatically arrested after violent shaking. Out a fire was reported in a building housing a turbine in the Onagawa nuclear power plant, located in Miyagi prefecture. But it was quickly extinguished and no radioactive leakage is detected. The largest power plant, Kashiwazaki-Kariwa in the central Niigata Prefecture, farthest from the epicenter, remained meanwhile operational. Some homes were 4,4millions however without electricity in the Northeast.

These enormous shock events are too rare, 10 to 100 times less often in France than in Japan where it is already 1000 years in the same place (movements of plates at 8cm per year and 10 times less in France, between Africa and Europe) i.e. 5000 to 10000 years for a huge earthquake with a tsunami for example on the Mediterranean coast as in Hyères, where clearly the earth tilts towards the sea burying the Moors mountains under water !! and elsewhere the same .
So this risk must be taken into account everywhere and not only on historic sites like Basel or Lisbon, because the next will be where we do not expect it (one in a few hundred years, 10 times less often than in Japan , with 10 to 20 years).
This type of simple assessment is much more accurate than that in force in France, as for nuclear power plants, and earthquake-resistant construction, which is an absurd and dangerous underestimation.

Three tsunami deposits have been identified within the Holocene sequence of the Sendai plain, all formed within the last 3,000 years, suggesting year 800 to 1,100 year recurrence interval for large tsunamigenic earthquakes. In 2001 it was reckoned that there was a high likelihood of a large tsunami hitting the Sendai plain as more than 1,100 years had then elapsed. [2] As for the other two large tsunamis recognized before the 869 tsunami, one was estimated to have occurred between about 1000 BC and 500 BC and the other about 500 BC and 1 AD. [3] In 2007 the probability of an earthquake with a magnitude of Mw8.1–8.3 was estimated as 99% within the following 30 years. [1] The 2011 Sendai earthquake and tsunami was larger than the predicted event, but occurred in the same area and caused major flooding in the Sendai area.

23 m the wave all the same:
http://www.slate.fr/lien/36049/vague-tsunami-23-metres
Tsunami wave peaked at 23,6 meters
The tsunami wave that hit the Japanese coast after the March 11 earthquake peaked at 23,6 meters, according to a study by the Japanese Port and Airport Research Institute released by Kyodo News. This terrifying height was calculated in the city of Ofunato, but it is not a record. It was reached in Japan in 1896 during the Meiji era with a 38,2 meter wave during the tsunami linked to the Sanriku earthquake.
But for researcher Kazuhiko Toda, the height of the tsunami wave of March 11 is not a reflection of its real strength because it was reduced by wave breakers and other existing facilities precisely to counter the tsunamis. Suddenly, he believes that the tsunami of March 2011 was in fact even more violent than that of 1896.
According to the Japanese meteorological agency, a wave of more than two meters can destroy given its speed which can reach 800 kilometers per hour of wooden houses. Concrete buildings can withstand waves up to 4 meters.
A Japanese seismologist, Yukinobu Okamura, denounced the Japanese government agency for nuclear risk assessment which in 2009 rejected warnings on the safety of a certain number of nuclear power plants in the event of natural disaster and in particular of tsunami of large scale. At Fukushima, the experts were only concerned with protecting the facilities from an earthquake and considered that a tsunami was a completely improbable hypothesis. Of the seven members of the commission that assessed the risks in Fukushima between April 2008 and June 2009 and met 22 times, none were tsunami specialists. The plant was protected by a wall capable of withstanding a six-meter wave.
The March 11 earthquake and the ensuing tsunami in Japan could become the most costly natural disaster in history with a latest estimate by the Japanese government for damage of 25.000 trillion yen, or about 230 billion euros. . The cost of Hurricane Katrina in August 2005 in the United States was 100 billion euros. In addition, the number of victims identified continues to increase in Japan and the latest figures show more than 9.700 bodies found and more than 15.500 people still missing.
