The first controlled nuclear reaction took place in 1942 at the University of Chicago. The first nuclear meltdown occurred at the Chernobyl Nuclear Power Plant in 1986, which is 44 years later.

How many years passed from the first controlled nuclear reaction to the first neclear meltdown?

The first controlled nuclear reaction occurred in 1942, while the first nuclear meltdown happened in 1952, so 10 years passed between the two events.


How many years passed from the first controlled nuclear reaction to the first nuclear meltdown in US history?

The first controlled nuclear reaction took place in 1942, and the first nuclear meltdown in US history occurred in 1979, marking a span of 37 years between these two events.


How many years passed from the first controlled nuclear reactoin to the first nuclear meltdown in US history?

I do not know as I don't have full access to INEL (the nuclear reactor development site in Idaho) records, perhaps a good idea for a FOIA request, the first meltdown would almost certainly have occurred in one of their test reactors long before any commercial reactor. I do know that the core of EBR-I (the first US breeder/power reactor prototype) was damaged in a meltdown on November 29, 1955; it was repaired and finally deactivated in 1964. This reactor has been decontaminated and is open for public tours (docent guided and self guided). I have been there 3 times (the first before decontamination of the floors were complete). I very much suspect they had at least one test reactor deliberately designed to thermally damage or even melt its core to study the effects.


Are nuclear bombs illegal in Berkeley CA?

Some US Cities have passed laws that make it illegal to possess atomic weapons in that city. Purely a symbolic gesture, and frankly, a waste of time and resources. Nuclear weapons are owned and controlled by the US Govt, which is not subject to city ordinances.


What kind of energy is given from a nuclear fission reaction?

The initial release of energy is in the form of kinetic energy of the fission fragments, but they are quickly stopped inside the fuel and the energy appears as heat, which is then passed into the coolant, whether water or gas.

Does nuclear radiation go away?

No, it doesn't.Wrong, it does. There are 2 types of nuclear radiation: prompt & decay.Prompt nuclear radiation occurs for a period of time while the reaction that generates it is happening. Examples are the flash of neutrons, light, x-rays, etc. when a nuclear bomb explodes as well as the sustained neutron flux as a nuclear reactor is in operation. When the reaction stops, prompt nuclear radiation goes away.Decay nuclear radiation occurs as radioactive isotopes decay to different isotopes. As the decay happens (which is a probabilistic process) the radioactive isotope is consumed. This follows an exponential function with one half of the current amount of the radioactive isotope consumed in each period of time called a halflife. While there will always be a tiny residue of the original radioactive isotope, for practical purposes it is considered to be negligible after 5 halflives have passed. When 5 halflives of the radioactive isotope decaying have passed, decay nuclear radiation is considered to have gone away for practical purposes.

Why is it inaccurate to say that only 31 people died as a result of the Chernobyl disaster?

Because after the nuclear reactor had a meltdown many people were exposed to radiation giving them cancer, and various other problems due to radiation exposure which would kill them. and not only does it effect the people that were exposed to it at that moment but radiation mutates your genes which are passed down to your kids causing many complications in newborn children.
