Physics Quiz on Nuclear Fission and Nuclear Reactor Types

Choose the correct statements regarding Nuclear Fission

1. Nuclear fission accompanies a loss of mass and release of energy.
2. Parent nucleus splits into only two daughter nuclei.
3. Nuclear fission is only an artificial process.

What are fissile and fertile materials?

Choose the correct statements regarding Uranium Enrichment

1. Uranium Enrichment is obtained by gas centrifuge cylinders
2. Nearly all reactors require Uranium Enrichment and breeder reactors may require enrichment as high as 30%.
3. Uranium Enrichment is necessary because U-238 is fissionable but U-235 is not.
