UNION** What is Fission?

Fission is a nuclear process in which a heavy nucleus splits into two smaller nuclei. An example of a fission reaction that was used in the first atomic bomb and is still used in nuclear reactors is represented in the diagram below.


Chapter 13 NUCLEAR FISSION Nuclear power can cleanly and safely meet a substantial portion of the additional base-load electricity generation capacity the United States will require by 2030 if (1) the operating lifetimes of existing nuclear plants are extended (where this can be done safely with ...

FUSION/FISSION QUESTIONS & ANSWERS 1. Why does a chain reaction not occur in uranium mines? There is not enough U-235 present in the ore. It is just 0.7% of the total uranium and it needs to be around 4% to allow chain reactions to occur.

7 Fission

CANDU Fundamentals 51 7 Fission In 1939 Hahn and Strassman, while bombarding U-235 nuclei with neutrons, discovered that sometimes U-235 splits into two nuclei of medium mass.
