There have only ever been two nuclear devices used on anyone--one was dropped on Hiroshima, the other on Nagasaki. They worked on the principal that if you get enough fissionable material in the same place at the same time, you'll get a runaway chain reaction that will cause the material to explode. So they figured out how much was enough to do this, stuck half of it at each end of a long tube, and put a lump of explosive behind one of them. When they threw this bomb out the back of an airplane, a sensor in the bomb detonated the explosive. It forced the two pieces together and the resulting explosion leveled the city they dropped it on. This is way too expensive to do on a large-scale basis, and the only reason they did it was that they needed something to use Right Now and they didn't really know how to make good bombs. They've found out since then that if you squeeze the atoms in a piece of material really close together it will cause the same kind of runaway chain reaction, so that's what they do now--build a sphere out of uranium and put explosives around it. When you throw this out the back of an airplane and set it off, it squashes the ball of uranium, which causes a runaway chain reaction, then an explosion that levels the city they drop it on.

A working nuclear reactor is a very simple energy conversion device?
No, it is not simple!!
How many people work in the nuclear reactors?
No one work inside a nuclear reactor, it is operated from outside.
What is the meaning of nuclear reactor?

What is meant by nuclear reactor?
It is a device where a controlled nuclear fission chain reaction occurs.
Which country is the first to use nuclear device?
US
Where can you get the wizard?
Melt ice with the thermal nuclear device.
What is nuclear bombing?
It Is a device used to destroy cities and their occupants. A single device has the power of several planeloads of conventional bombs.
How does nuclear energy power a device?
Typically the nuclear energy is converted to electricity and the electricity powers the device. No much differently than the chemical energy in fossil fuels is often converted to electricity and the electricity powers the device.
Can nuclear fission be used anywhere in the world?
yes on condition of the availability of the necessary nuclear fission device (nuclear reactors or critical assemblies).
If a device does not work after the OS upgrade what can you do?
If the device does not work then you will have to update the firmware on the device
Which country has successfully tested a nuclear device?
North Korea
Which country exploded first its nuclear device?
All countries that have exploded nuclear devices have exploded their first devices. The USA was the first to detonate such a device and the only country to use nuclear warheads in combat. The most recent countries to test nuclear devices are India, Pakistan, and North Korea.
Where does a nuclear engineer work in?
watch the simpsons... homer is a nuclear engineer, and he works in a powerplant therefore; nuclear engineers work in nuclear powerplants THE END!
What does a Nuclear radiation device measure?
The device is called a Geiger counter and it has a measurement scale in Microsieverts.
