This part is the core of the nuclear reactor containing the nuclear fuel.
Fuel cells are an important part of a nuclear reactor. The component that powers the nuclear reactor is the reactor core and the fuel cells are found inside and hold uranium dioxide.
In light water reactors the new fuel has about 4 to 5 percent U-235, which is the fissionable part, the rest being U-238. In some countries mixed oxide fuel is used (MOX) which contains some Plutonium as well as U-235, but the fissionable content is much the same. Heavy water or graphite reactors can use natural uranium, which contains 0.7 percent U-235.
It's a complicated story, there are many different elements in the fission products, and they have widely different half lives and radioactive characteristics. Some decay quickly and turn into other isotopes which may have much longer half lives. I recommend you read the first part of the linked article, if you want to go further there is much more detail available in the rest of the article. Note that nuclear reactors and nuclear weapons produce differing actual quantities and types of fission products because in the reactor they are retained in the spent fuel whereas in a nuclear explosion they are scattered widely and so have a more immediate effect.
yes it is.... it is the main part of a nuclear weapon.
The central active core fuel assemblies.
Fuel in a nuclear reactor is located in the core of the reactor. It is there that the fuel, which is sealed (welded) inside plates or tubes, is situated in fuel bundles.

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.
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 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.
In the reactor core, which is the volume filled with the fuel assemblies
The fuel itself, which contains some very radioactive material, so it must be kept in a safe condition at all times, both during operation and after it is unloaded and stored
