A reactor is an application for an inductor. Inductors oppose any change in current. So a reactor is used to 'slow down' (a simplification) any significant change in current arising from, say, a short-circuit fault.
Answer: Reactors are also used for power-factor correction. If a transmission line has a load with a permanently poor power factor, reactors would be connected at the receiving end to correct the power factor and thus reduce the current and the power losses in the resistance of the line.
In order to limit the short circuit current to that value which circuit breaker can handle reactors are used.They are also used for improve the power factor...

The very first nuclear reactor was Chicago Pile 1. It was built for research and scientific use. The first nuclear reactor outside of a university was built (at Hanford, Washington) primarily to yield plutonium for the atomic bomb destined for Nagasaki, Japan. Nuclear reactors were built primarily for electrical generation beginning in about 1951.
This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma.
This item is normally seen in electrical switch gear (or called "Starter "/ "Motor drive") . This device is to reduce the inrush current during motor starting. Another item "Line reactor" .
Saskatoon Electrical System Substation was created in 1929.

In my line of work that is an Electrical High Voltage substation that is brand new. It is being built from a green field into an energized fully functional substation yard. There is no existing substation or remodeling of an existing one being done.
Very carefully

They are places to avoid because they can make you seriously ill.

A nuclear reactor contains a nuclear reaction, provides support for the control mechanisms for the reaction, and provides for the transfer of heat to machinery that will use it to produce electric power.
Not normally, but depending on the foreman you might get to bend the rules a little.
The reason for having many reactors is because you can produce more electrical energy from them. Also Japan use BWR type reactors(Boiling Water Reactor) which are not as efficent as a more commonly used PWR reactor(Pressurized Water Reactor).
For an electrical output of say 1000 MWe, the reactor output will be about 3000 MW thermal.
