The number of fuel pins in a reactor will vary depending on its design and objectives.
In one reactor that I worked with, I seem to recall 137 fuel assemblies, with four bundles each, with 62 fuel pins each. That translates to 33,976 fuel pins in the reactor, each about 12 feet long.

What part of the nuclear reactor is the fuel located in?
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.
What are fuel rods?
Nuclear fuel rodsFuel rods are long, cylindrical rods or long, flat plates containing fissile material (usually uranium) in a nuclear reactor core. The uranium is in rods or plates so it can be bundled into a fuel element and fixed in place to make up the core. The spacing and arrangement of the rods and, beyond that, the bundles themselves, is the key to reactor geometry.Other rods in the reactor called control rods are also moved into channels in the reactor core, but these have the opposite effect. They contain neutron-absorbing materials that can moderate (or stop) the fission reaction that takes place when a critical mass is achieved. Control rods are pulled to start the reactor up, and are put back in to shut the reactor down.
How does a nuclear meltdown happen?
It can happen if the reactor fuel rods overheat, and that can happen if they are not adequately cooled after the reactor is shutdown
What is a part of a nuclear power plant that undergoes a fission 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.
What are the mechanical protections need in reactors?
If a reactor cannot be properly controlled, it will quickly overheat. This is what happend at Chernabyl, Russia. The fuel rods melted into the reactor floor and released a large plume of radio-active steam. The way to immeidatly shut down a reactor is a S.C.R.A.M.(Safety Control Rod Axe Man). A reactor has control rods that exorb radiation and stop the reaction when lowered onto the fuel rods. The first reactor had a rope holding up the control rods. A guy with an axe would chop the rope if the reaction got out of control. Another is shielding. The core is surounded with lead and concrete that shields people from the radiation from the reactor.
What rods housed within a nuclear reactor?
fuel rods and control rods
What part of the nuclear reactor is the fuel located in?
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.
Which section of a nuclear reactor does nuclear fission occurs?
The fission happens in the fuel, which is usually in fuel rods inside the reactor. The rods are spaced at a particular distance apart and fill the reactor.
What rods hold pellets of uranium?
Known as fuel rods, these are hollow metal rods that contain the uranium fuel for a nuclear reactor.
How long are the fuel rods typically left in the reactor core in a BWR or a PWR?
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.
Fuel rods in the reactor vessel are made of?
Uranium-235
What is the next step in a nuclear reactor after nuclear fission occurs in fuel rods?
Water is pumped around the fuel rods.
What are fuel rods in nuclear plants made of?
The fuel rods used in a nuclear reactor are made from uranium 235(U-235).
Large chamber where fuel rods are located?
Nuclear reactor core

How many control rods are there in a nuclear reactor?
The number of control rods in a reactor will vary with the size and the design.
