Boron is used inside a nuclear reactor inside a control rod which is used to 'soak' up the neutrons inside the nuclear reactor, a control rod can be used to control the rate of fission inside a nuclear reactor.
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.
This part is the core of the nuclear reactor containing the nuclear fuel.
Uranium
The fuel rods used in a nuclear reactor are made from uranium 235(U-235).
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 length of time we see fuel rods left in the core of a reactor will depend on the time it takes to deplete the nuclear fuel in those rods. Reactor design, specifically fuel rod design, and the rate at which the fuel is consumed during operation all have an effect. Typical life of the fuel in a nuclear reactor at a power station is several years.

Nuclear reactor kinetics is the branch of reactor engineering and reactor physics and control that deals with long term time changes in reactor fuel and nuclear reactors.
for pressurized light water reactor type, as an example, the nuclear reactor components are * Reactor vessel (that contains the nuclear fuel and surrounded with water and contains control rod for power control and for safety) * reactor coolant pump * steam generator * reactor pressurizer * piping out of the vessel to the pressurizer, from pressurizer to steam generator, from steam generator to reactor coolant pump, and from pump back to the reactor vessel.
The used fuel in a nuclear power plant is the nuclear fuel being discharged from the nuclear reactor after being irradiated during reactor operation. It is usually composed of trans-uranium heavy elements, a wide variety of fission products (that resulted from the nuclear fission processes in the nuclear reactor) and products of radioactive decay (produced before and after fuel discharge from the nuclear reactor).
nuclear fuel (thorium, uranium, etc.), electron absorbing rod (krypton, boron, etc.), projectile (which give high speed to electron/proton),
In dealing with a nuclear reactor SCRAM stands for Safety Control Rod Activator Mechanism. Nuclear reactors can be quite dangerous.
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.
I didnt measure when I had it in hand but I would guess 12cm diameter, and maybe 80 cm long, for a magnox reactor anyway
