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.
In the core.
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 core of the nuclear reactor includes:nuclear fuel elements (composed of the fuel meat covered with cladding)reactor coolantreactor moderator (for thermal reactors)control elementsmeasuring instrumentsstructural and support structures
A meltdown occurs when a severe failure of a nuclear power plant system prevents proper cooling of the reactor core, to the extent that the nuclear fuel assemblies overheat and melt. A meltdown is considered very serious because of the potential that radioactive materials could be released into the environment. A core meltdown will also render the reactor unstable until it is repaired. The scrapping and disposal of the reactor core will incur substantial costs for the operator.
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 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.
This part is the core of the nuclear reactor containing the nuclear fuel.

Fissionable substances.
No, a nuclear weapon needs a specific geometry to detonate, and it has to be held in this position by very high explosives to keep it in this shape. In a nuclear reactor, if the reactor core goes critical then the force of the expanding coolant will blow the reactor apart, preventing a nuclear blast.

Within the reactor core of a nuclear power plant all the actions and reactions take place. These reactions release energy in the form of heat. This can be harnessed to provide power to the building.
