text: For heavy nuclides, it is an exothermic reaction which can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments (heating the bulk material where fission takes place).
text: Nuclear fission takes place when a large, somewhat unstable isotope (atoms with the same number of protons but different number of neutrons) is bombarded by high-speed particles, usually neutrons.
text: Whether fission takes place, and indeed whether capture occurs at all, depends on the velocity of the passing neutron and on the particular heavy nucleus involved.
text: Meitner and Frisch carried out further experiments which showed that the U-235 fission can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments (heating the bulk material where fission takes place).
text: However, it not been observed that fission takes place very easily with the slow neutrons in uranium-235 and plutonium-239, and mostly these two are used for fission purposes.
text: Fast neutrons" are moderated in nuclear reactors by the coolant (usually DI water) to slow them down for more fissions to take place...thus the term "thermal reactor.
text: Fission of heavy elements is an exothermic reaction and can release substantial amounts of useful energy both as gamma rays and as kinetic energy of the fragments (heating the bulk material where fission takes place).
text: They immediately contacted a fellow scientist in the field, Lise Meitner, who carried out calculations to demonstrate that fission had taken place.

text: Nuclear fission takes place when high-speed particles, neutrons are bombarded on the unstable isotope.
text: After this astonishing discovery, physicists began probing the uranium mines in Oklo for more evidences and eventually discovered at least sixteen sites within this region where spontaneous nuclear fission had taken place.
