Boron Carbide.
This is used in the nuclear reactor that is known as Boiling Water Reactor (BWR) in which heat produced by the nuclear fission in the nuclear fuel allows the light water reactor coolant to boil. Then, the nuclear reactor moisture separator is used to increase the dryness of the produced steam before it goes to the reactor steam turbines.
Typically, Uranium-235 is used as fuel in nuclear reactors.
The number of control rods in a nuclear reactor can vary depending on the design and size of the reactor. Typically, a nuclear reactor can have anywhere from 50 to 100 control rods. These rods are used to control the rate of the nuclear reaction by absorbing neutrons and regulating the power output of the reactor.
An artificial nuclear reactor is a device that initiates and controls a sustained nuclear chain reaction. This reaction produces heat, which is used to produce electricity in nuclear power plants. The fission process in these reactors generates energy by splitting atomic nuclei.
Coolant, such as water or a specific type of liquid metal, is used in a nuclear reactor to absorb the heat released during the nuclear fission process. The coolant carries away the heat and helps to regulate the temperature within the reactor to prevent overheating.

This part is the core of the nuclear reactor containing the nuclear fuel.
Boron is used in nuclear reactors as a neutron absorber to help control the nuclear reaction by capturing excess neutrons and reducing the reactor's overall reactivity. By introducing boron into the reactor coolant or as control rods, operators can regulate the rate of the nuclear fission process.
Fuel pellets are typically clad in Zircalloy, if that was your question. Especially in water cooled reactors.
Never a nuclear reactor is used in airplanes. However, it is used in submarines.
If you are talking about the Nuclear Reactors in Japan, they were damaged because when they lost power, the water pumps used to cool them stopped, and all of the nuclear material overheated.
The amount of coolant used in a nuclear power reactor can vary depending on the design of the reactor. Generally, a nuclear power reactor may use thousands to millions of gallons of water or a different coolant material to remove heat generated during the nuclear fission process. The coolant circulates through the reactor core to transfer heat and help regulate the temperature of the reactor.
A reactor is a device that is designed to contain and control nuclear reactions, producing heat that can be converted into electricity. Reactors are used in nuclear power plants for generating electricity and in research facilities for various scientific purposes.
The fuel used in a nuclear reactor is typically uranium. Specifically, the most common type of uranium used is uranium-235, which undergoes nuclear fission to produce energy in the reactor.
Graphite is used as a moderator in nuclear reactors to slow down neutrons produced during nuclear fission. Slower neutrons are more likely to cause additional fission reactions, allowing for a sustained nuclear reaction. Graphite is also used as a structural material in some reactor designs.
One material that can be used to cool down a nuclear meltdown is water. It is commonly used as a coolant in nuclear reactors to absorb excess heat. Other materials like liquid sodium or helium may also be used in some reactor designs.
