Nuclear power comes from the release of binding energy (Strong Atomic Force) that hold nuclei together.
In a reactor core, we use neutrons to fission Uranium-235 (and occasionally others, such as Uranium-238, Plutonium-239, and/or Thorium-232) atoms into two smaller atoms of various elements. The mass of the contributing particles is greater than the mass of the resulting particles. This mass differential is manifest as excess energy, and it is released as heat and radiation.
Each fission event produces more neutrons, and those go on to sustain the reaction by causing more fission events. That is why its called a chain reaction.
Nuclear fission takes place in the nuclear fuel rods that are placed in the reactor core that is situated in the reactor pressure vessel. The reactor pressure vessel is usually situated inside the reactor containment.
The reflector in a nuclear reactor helps to reflect neutrons back into the reactor core, increasing the chances of nuclear reactions occurring. The reactor core is where the nuclear reactions take place, generating heat that is used to produce electricity.
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.
Lowering control rods in a nuclear reactor will result in the absorption of neutrons, which decreases the rate of fission reactions happening in the reactor core. This leads to a decrease in heat production and ultimately reduces the power output of the reactor.
The nuclear fuel is found in the fuel rods. These fuel rods are formed into fuel bundles called fuel assemblies, and together they make up the reactor core.
Yes, we can increase the thermal power of a nuclear reactor without changing the core of the reactor; primarily by:increasing the coolant mass flow rate,modifying the control rod patterns, andupgrading the turbo generator system

core
The nuclear fuel is typically contained in the reactor core, which is a central part of the nuclear reactor where the fission reaction takes place. The fuel rods, which contain the nuclear fuel pellets, are inserted into the reactor core during operation.
The core of the reactor contains the nuclear fuel. Having a moderator in place within the core ensures that the nuclear fuel is processed at an accurate time duration. This can prevent serious problems from occurring within the entire nuclear reactor.

It's really just a matter of degree, all reactors produce some power. Those used in a power plant will produce perhaps 3000 to 5000 Megawatts thermal. Low power reactors producing a few kilowatts are used for experiments, teaching in universities, and for producing radioisotopes by irradiating samples, but reactors in this sort of power level would not be harnessed to produce electricity, the heat produced if large enough would be removed and rejected to the atmosphere or to a water cooling circuit. This makes them simple to operate and to start and stop as required.

Fissionable substances.
The nuclear fuel is found in the fuel rods. These fuel rods are formed into fuel bundles called fuel assemblies, and together they make up the reactor core.
The amount of coolant used in a nuclear power reactor can vary depending on the design of the reactor. Generally, a nuclear power reactor may use thousands to millions of gallons of water or a different coolant material to remove heat generated during the nuclear fission process. The coolant circulates through the reactor core to transfer heat and help regulate the temperature of the reactor.
