The uranium 235 atoms in the nuclear fuel are what actually fission, or split into two other atoms. The uranium is in ceramic fuel pellets that are inserted into fuel rods, that make up fuel elements, that are in the reactor core that is located in the reactor vessel of the nuclear power plant. After the fuel has been in the reactor it begins to produce plutonium 239 atoms within the fuel which will also undergo a fission reaction.
The fission reaction takes place inside the nuclear reactor. <------------------

The chain reaction can be controlled, and it can be stopped. It is controlled in a nuclear power plant, and it is stopped when the plant shuts down, as it does periodically for refueling.
Fission refers to a nuclear reaction wherein a heavy nucleus splits spontaneously, with the release of energy. The ideal location of fission is in a power plant inside a nuclear reactor.
The fission reaction is controlled through use of high neutron capture material as Boron, Gadolinium, Cadmium, ... etc.

There are emergency safety system that could be used to bring the nuclear plant again under control.
