+# Module 5.1 - Reactor Overview
+Classifying Reactors
+1. Type of reaction
+2. Moderator material
+3. Coolant
+4. Generation (I-IV)
+5. Use
+Heat is created from fission. Kinetic energy from the decay products moving around is kind of what we see as "temperature".
+# Module 5.2 - Neutron Multiplication
+## Criticality Conditions
+### Neutron Economy
+A successful reactor must
+1. Create enough excess neutrons to continue the reaction
+2. Not have so many neutrons that it becomes uncontrolled
+3. Consider material limits
+Letting too many neutrons leak is expensive. This is the gas!
+### Neutron Balance
+Rate of increase = Production - absorbed - leakage
+0 = Critical - Steady State - Static
+\> 0 Supercritical - increasing - Kinetic/Dynamic
+\< 0 Subcritical - decreasing - Kinetic/Dynamic
+### Neutron Life Cycle
+1. Birth 
+2. Lifetime. Gets scattered around. Sneaky little fella
+3. Death 😬 Leaks from the system or is absorbed
+### Multiplication factor
+$$k = \frac{\text{Number of neutrons in one generation}}{\text{Number of neutrons in preceding generation}}$$
+Measures how many neutrons produced by each neutron born.
