Chicago in a Squash Court, Enrico Fermi operated CP-1 reactor in 1942. It was a nearly spherical assembly of "greasy" black graphite blocks with uranium balls distributed in holes bored into the graphite. It had no shielding or cooling system, but was never operated for more than a few minutes at a time and never at a power level over 1W.

Why must neutrons in a chain reaction be controlled?
Neutrons in a nuclear fission chain reaction must be controlled for two reasons... First, they must be moderated, or "slowed down", to exactly the right level of energy required to sustain the reaction. This is because, initially, the neutrons are too fast to sustain the fission reaction. They must be slowed down, but not too much, otherwise the reaction will stop. Second, they must be controlled. You want the reaction to proceed at an orderly pace, at a constant rate. To do this, you need, on a statistical average, exactly one neutron to go on to fission one atom to produce one parcel of binding energy release and one neutron, to repeat without multiplying or dividing. This is what we call KEffective = 1, where the rate of reaction does not change. Moderation and control. In tight balance. Easily upset. Fortunately, when upset, the tendency is to shutdown. That is engineering safety.

How is the number of neutrons in an assembly involved in creating a sustained nuclear chain reaction?
This answer can not be accurately answered without first knowing what type of nuclear reactor it is. A pressurized-water nuclear reactor is probably the most common so I'll briefly talk about some factors that affect the number of chain reactions in that type of nuclear reactor. First of all, the temperature of the water entering the reactor core will affect the number of chain reactions. The colder the water, the greater the number of reactions. This is primarily because the colder water is more dense and thus releases more neutrons which speeds up the chain reaction rate. Of course, reactor operators, wishing to control the number of chain reactions in order to make the reactor stable may raise or lower "rods" which will be made of a material that tends to absorb neutrons and thus lowering the chain reaction rate. These are the two most common factors affecting chain reaction rate. Would delve further into this question but it gets rather complicated at this point.
How has having an atomic model improved science?
the first sustained and controlled nuclear chain reaction by Enrico Fermi in 1942
What is the nuclear age?
It's a general term used to apply to the time following the advent of nuclear technology. It could have begun when the first controlled nuclear chain reaction took place, or when the first nuclear bomb was detonated. That was in the 1940's.
When was the first controlled nuclear explosion in the US?
Nuclear explosions are not controlled. Nuclear reactors are controlled.The first controlled nuclear reaction in the US was on December 2, 1942.The first nuclear explosion in the US was on July 16, 1945.
What was the year of the first nuclear chain reaction?
1942

When was nuclear energy first used and what was its effect?
CP-1 in Chicago in 1942 was first operating nuclear reactor. no effect except confirmation that chain reaction worked and could be controlled.
