Term
Heavy unstable nuclei split apart into two smaller nuclei.
Definition
Fission
Term
Two lightweight nuclei join together to form a heavier nucleus.
Definition
Fusion
Term
Unstable nuclei release a huge amount of energy when they split.
Definition
Fission
Term
Lighwheight nuclei release a hug amount of energy when they join.
Definition
Fusion
Term
Heavy nuclei will not release excess energy by splitting if they are as light as the element iron or lighter.
Definition
Fission
Term
Lightwheight nuclei will not release excess energy if the nucleus generated by fusing is heavier than iron.
Definition
Fusion
Term
Reactions often produce daughter products that are radioactive. This causes a radioactive waste problem for nuclear energy production.
Definition
Fission
Term
Reactions often do not produce products that are radioactive. This makes the reactors an attractive possibility for nuclear energy production.
Definition
Fusion
Term
Many countries, including Canada, generate some electrical power through these reactions.
Definition
Fission
Term
No commercial reactors are in use or under construction.
Definition
Fusion
Term
Research continues to try to produce environmentally friendly nuclear power generation.
Definition
Fission
Term
Research continues to try to produce a nuclear reactor.
Definition
Fusion
Term
This reaction is used in modern nuclear weapons by itself or to produce an explosion that will generate sufficient heat and pressure to trigger the other reaction.
Definition
Fission
Term
This reaction is used in modern nuclear weapons to generate most of the energy released in the blast. This reaction needs the heat and pressure from the other nuclear explosion to get it started.
