slow down the chain reaction by absorbing free neutrons
The cannot as they are inserted in holes in steel support frames that hold several dozen fuel rods. When changing fuel, complete steel support frames are switched and individual rods are not handled.
A meltdown occurs in a nuclear reactor when the core overheats and the fuel rods are damaged, releasing radioactive material. This can happen due to a loss of coolant, causing the fuel rods to become exposed and overheat. If not controlled, this can lead to a breach of the reactor containment and a release of radiation into the environment.
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.
Control rods made of materials such as boron or cadmium are used to slow down nuclear reactions in a nuclear reactor by absorbing neutrons. When inserted into the reactor core, control rods can regulate the rate of the nuclear reaction by absorbing excess neutrons and thus controlling the release of energy.
It is called a nuclear meltdown when fuel rods in a nuclear power plant generate so much heat that they start to melt. This can lead to the release of radioactive material and poses a serious threat to both human health and the environment.
Fuel rods are used to hold pellets of uranium in nuclear reactors. These rods are typically made of a material like zirconium to encase the uranium pellets and control the nuclear fission reactions within the reactor.
The cladding material of nuclear fuel rods is typically made of zirconium alloys, such as zircaloy. Zirconium is chosen for its high corrosion resistance, mechanical strength, and low neutron absorption properties. These characteristics help to prevent the release of radioactive materials from the fuel rods during operation.
Nuclear fuel rods are dangerous because they contain radioactive materials that can emit harmful radiation when not properly shielded. If the rods are damaged or not handled correctly, there is a risk of a nuclear meltdown or release of radioactive material into the environment, which can cause severe health and environmental consequences. Proper storage and disposal of nuclear fuel rods are necessary to mitigate these risks.
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.

In water reactors the fuel rods are clad with zircaloy sheaths
No, but control rods do.
