Fewer minor actinides are. The induced nuclear fission of uranium 235. Nuclear fission neutron strikes a large atomic nucleus releases more neutrons and heat energy additional neutrons release more energy in a chain reaction.

Easier to run the reactor safely. Powerpoint presentation for chapter 18 of an introduction to chemistry. 25 significant nuclear reactions fusion nuclear fusion is the process by which.

A nuclear reactor is a device in which nuclear chain fission reactions are initiated controlled and sustained at a steady rate as opposed to a nuclear bomb in which the chain reaction occurs in a fraction of a second and is uncontrolled causing an explosion. To control it boron rods are used because boron hasthe property to absorb neutrons. Nuclear bombs are created using this concept.
