The sun has burned for about 6 billion years and will burn for about 6 billion more.
The place where controlled nuclear fission reactions take place is called a nuclear reactor. In a nuclear reactor, uranium atoms are split in a controlled manner to produce heat energy, which is used to generate electricity.
Chicago, 1942
Those reactions that take place in functioning nuclear reactors (i.e not Chernobyl or Fukushima when the accidents happened).
Helium plus released energy (heat)
sun, fusion of hydrogen nuclei making helium nuclei (not radioactive)nuclear reactor, fission of uranium nuclei making a wide variety of different fission product isotopes having mass numbers from 72 to 161 (all very radioactive)
The reflector in a nuclear reactor helps to reflect neutrons back into the reactor core, increasing the chances of nuclear reactions occurring. The reactor core is where the nuclear reactions take place, generating heat that is used to produce electricity.
Nuclear fission reactions often take place in nuclear reactors. The key factors that contribute to their occurrence in that location include the presence of fissile materials such as uranium-235 or plutonium-239, control rods to regulate the reaction, and a moderator to slow down the neutrons.
They originate from nuclear reactions, such as those that take place in a star, when cosmic rays hit atoms and in supernovae.
The part of a nuclear reactor in which the fuel is located is called the core. This is where the nuclear fission reactions take place, producing heat that is used to generate electricity.
Yes, chain reactions take place in nuclear reactors. In a nuclear reactor, the chain reaction involves the splitting of uranium atoms (fission) which releases energy and more neutrons, leading to further fission reactions. Control rods are used to regulate and maintain the chain reaction at a steady rate.
Chemical reactions in the body take place in water.
