No, Hawaii is currently not in danger of radiation from the incidents involving the nuclear reactors in Japan.
Before the Fukushima Daiichi Disaster, there were 54 operational nuclear reactors in Japan. Three of those melted down, and one had problems that rendered it inoperable. The government has decided the other two reactors at Fukushima Daiichi cannot be restarted. Also, as other reactors have been shut down for maintenance or refueling, they have not been restarted, with the result that now, in early December 2011, only eight Japanese reactors remain in operation.
The tsunami destroyed many buildings and damaged nuclear reactors
During the Fukushima Daiichi nuclear disaster in Japan, three of the reactors experienced hydrogen explosions. These explosions occurred in Reactors 1, 3, and 4.
There are over 400 nuclear reactors around the world.
the cause of the melt down of the reactors in japan is the water that is needed to cool down the reactors
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.
France has 56 nuclear reactors in operation. This makes France one of the countries with the highest reliance on nuclear energy in the world.
Most nuclear reactors are thermal-neutron reactors. A few fast breeder reactors have been built, but not many.
Sweden currently has 3 active nuclear power plants with 10 reactors.
As of 2021, there are 93 commercial nuclear reactors operating in 28 states in the United States. These nuclear reactors are spread across 56 nuclear power plants.
It is impossible to build ANYTHING in japan that is not on a geological fault. That is how the islands formed.
