| BINDING ENERGY | ENERGY RELEASED WHEN A NUCLEOUS IS FORMED OR REQUIRED TO SEPERATE THE NUCLEOUS INTO INDIVIDUAL NUCLEONS |
| MASS DEFECT | THE MASS OF A NUCLEOUS IS LESS THAN THE SUM OF THE MASSES OF THE INDIVIDUAL NUCLEONS THAT COMPOSE THE NUCLEOUS |
| NUCLEONS | PARTICLES THAT FORM A NUCLEOUS |
| FISSION | SPLITTING A NUCLEOUS |
| FUSION | COMBINING NUCLEI INTO ONE NUCLEOUS |
| RADIOACTIVITY OR DECAY | SPONTANEOUS DECAY OF THE NUCLEOUS |
| ALPHA DECAY | PARTICLE EMMITTED FROM THE NUCLEOUS MADE UP OF TWO PROTONS AND TWO NEUTRONS |
| BETA DECAY | HIGH SPEED ELECTRON EJECTED FROM A NUCLEOUS |
| GAMMA RADIATION | HIGH FREQUENCY ELECTROMAGNETIC RADIATION EJECTED FORM A NUCLEOUS |
| HALF LIFE | THE AMOUNT OF TIME FOR HALF A SAMPLE OF AN RADIOACTIVE SAMPLE TO DECAY |
| PARENT NUCLIDE | THE SUBSTANCE UNDERGOING DECAY AND PRODUCING A DIFFERENT NUCLIDE |
| DAUGHTER NUCLIDE | THE NEW NUCLIDE PRODUCED FROM THE DECAY OF AN ATOM |
| CONTROL RODS | USED TO ABSORB NEUTRONS TO SLOW DOWN THE RATE OF THE REACTION |
| MODERATORS | SURROUNDS FUEL CYLINDERS AND SLOWS THE NEUTRONS DOWN SO THE FUEL CAN CAPTURE THE NEUTRONS |
| CRITICAL MASS | THE MASS REQUIRED FOR ONE NEUTRON PER EVENT TO CAUSE ANOTHER EVENT |
| SUBCRITICAL MASS | MASS OF FUEL WHERE LESS THAN ONE NEUTRON PRODUCED PER EVENT CAUSES ANOTHER EVENT TO OCCUR |
| SUPER CRITICAL MASS | MORE THAN ONE NEUTRON PRODUCED PER EVENT CAUSES ANOTHER EVENT TO OCCUR |
| CHAIN REACTION | SEL SUBSTAINING REACTION REQUIRES AT LEAST ONE NEUTRON PER EVENT TO CAUSE A NEW EVENT |
