Fuel pellets are typically clad in Zircalloy, if that was your question. Especially in water cooled reactors.
ceramic can withstand high temperature
which material used in glassline reactors? What is glassline material ? Basic
a reactor is generally termed as an autoclave reactor,when it is a high pressure batch reactor.mostly this kind of reactors are used for sterilization the reactants..
Some hazardous substances used in nuclear reactors include uranium, which serves as fuel, and plutonium, a byproduct of nuclear reactions that can be used in advanced reactors. Other hazardous materials include radioactive isotopes like cesium-137 and strontium-90, which can be produced during fission. Additionally, substances like boron and cadmium are used as neutron absorbers, and coolant chemicals can also pose hazards if improperly handled. Proper safety measures are essential to manage these substances and mitigate risks.
Kalpakkam has both Thermal reactor (Madras Atomic Power Station) and Fast Breeder Reactor -FBTR and PFBR (Under construction). In MAPS (thermal reactor) it is Heavy Water (D2O) Which acts as a coolant as well as moderator, where as in Fast Breeder Test Reactor (FBTR) and Prototype Fast Breeder Reactor (PFBR) Sodium (Na) is used as coolant. Since there should not any moderators for fast reactors D2O will not be used as coolant in fast reactors.

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.
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.
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.
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.
