PLEASE ANSWER QUICK!! 1. Describe some of the types of power reactors that have been designed.
2. Distinguish between nuclear fission and nuclear fusion.
3. Describe the benefits and risks associated with nuclear energy.

1. Several power reactors have been designed primarily to produce electricity. These include

A pressurized-water, graphite-moderated reactor shielded by concrete

A graphite-moderated reactor that uses enriched uranium fuel

A reactor that uses liquid sodium as a coolant

A reactor that uses moderately enriched uranium as the fuel and ordinary water as the moderator in place of graphite

2. During nuclear fission, atoms are split into new, lighter atoms. As they split, energy is produced.

During nuclear fusion, light elements are combined into a heavier element with a resultant release of great amounts of energy. Extremely high temperatures are needed to trigger this. This is the source of the sun’s heat. Conditions that must be met to achieve controlled fusion are more complex than those required for fission.

3. Great amounts of energy can be generated through the process of nuclear fission to produce energy that can be used by consumers.

If the chain reaction within nuclear fission isn't controlled, tremendous explosions can occur. Leaks and radiation exposure can also be dangerous to human health.
