Shows a control rod

Shows a fuel rod

Shows the moderator

Moderator's function

Slow down neutrons to increase fission

Fuel rod's function

Where fission of U-235 occurs producing heat

Control rod's function

Blocks neutrons to slow or stop fission from occuring

Fission

Splits the atomic nuclei

Fusion

Joins atomic nuclei together

Breeder reactor

Fission reactor that turns non-fissionable isotopes into fissionable isotopes

Critical mass

Having enough fissionable atoms close enough together for the chain reaction to occur

Chain reaction

When the 3 neutrons released from fission cause 3 more atoms to fission again and again

Fission bomb is set off when

Subcritical masses are pushed together to form critical mass

Fusion occurs under conditions of

High temperature and pressure

Why its hard to start fusion

Because atomic nuclei repel each other

Enriching uranium

Separating fissionable U-235 out of a mixture of uranium isotopes

Sulfur

Burning coal with this in it cause acid rain
