The reactors af Fukushima Daiichi were built by different companies, but they were all designed by GE.
There were six reactors at Fukushima Daiichi. At the time of the earthquake, three of these, reactors 1, 2, and 3, were operating. Reactor 4 was shut down for refueling, and reactors 5 and 6 were in cold shutdown.

Present 2013. None. All are active. Fukushima has been 'Decommissioned'.
The reactors at Fukushima still have their full load of uranium from when they were operating. Radiation levels are far too high to have permitted workers to remove any, also there is the structural damage that has probably jammed fuel rods in place which would prevent removal without demolishing the reactors first.
The tsunami that hit Japan wiped out the cooling systems for the reactors at the Fukushima Daiichi power plant. The reactors are currently overheating and releasing dangerous amounts of radiation into the atmosphere
The nuclear reactors did not explode. The problem was that the cooling system failed, and they overheated. Some water got so hot that it split into hydrogen and oxygen, and the hydrogen burned in the oxygen, which cause it to "pop"
Though Fukushima has lost 4 of its Nuclear Reactors, There are many more Nuclear Reactos running in Japan, Secondly Japan is mostly using Coal and Gas to compesate for fukushima.
Those reactions that take place in functioning nuclear reactors (i.e not Chernobyl or Fukushima when the accidents happened).
The solidified fuel and debris that melted in a meltdown is often called lava.
Yes. That's how the diesel generators were damaged at Fukushima Daiichi, leading to the current crises there. Note that the reactors themselves were not touched by the tsunami because of the containment structures in place.
