The Nuclear Technology Quiz

1.

A gun-type nuclear weapon …

… uses plutonium to create an explosion

… is a nuclear weapon delivered by a recoilless rifle

… fires two sub-critical masses into one another to form one supercritical mass

2.

Fissile Materials are:

Very stable materials whose nuclei cannot break apart when bombarded with neutrons.

Materials whose nuclei can break apart when bombarded with neutrons, emitting more neutrons than they absorb.

New materials produced only as a result of nuclear reaction.

3.

Which of the following groups of countries are all known or widely believed to have produced nuclear weapons?

Russia, South Africa, North Korea, China

United States, Finland, France, Israel

United Kingdom, Switzerland, Argentina, Pakistan

4.

The atom is:

A key component used only in nuclear weapons and nuclear power reactors

The smallest entity known to humanity

The basic building block of all material

5.

The minimum amount of material necessary to sustain a chain reaction is called:

A critical mass

A nuclear mass

A sub-critical mass

6.

Which of the following nuclear weapon is, relatively speaking, the easiest to manufacture

Hydrogen device

Gun-type device

Implosion device

7.

Centrifuge enrichment...

...exploits the mass difference between U-235 and U-238 to increase the percentage of U-235 in the material

...is technologically complex and used only for the production of nuclear weapons

...forces the lighter U-238 to the top of the centrifuge, where it can be "scooped off"

8.

Uranium-238 and uranium-235 are:

two different chemical elements

two isotopes of the same element, with different atomic mass

both capable of producing a nuclear explosion

9.

In the context of producing nuclear weapons-usable materials, which components of the nuclear fuel cycle are the most sensitive?

Enrichment and reprocessing

Mining and milling

Conversion and fuel fabrication

10.

Plutonium is...

...widely available in nature and is obtained by mining

...obtained by reprocessing spent fuel from nuclear reactors

...a different isotope of uranium
