Nuclear Fusion and Fission Reactors as of CCEA A2 Physics spec
Sample Data
| Front | How are divertors used within fusion. |
| Back | Divertors are tungsten 'targets' that extend into the plasma, and some plasma particles strike it and heat the tungsten. This heat is used for additional electricity creation. Tungsten is used due to its high melting point. 50 of these are positioned around the vacuum vessel. |
| Front | Why is Deuterium and Tritium used? |
| Back | The provide the most net energy yielded out of the possible reactions |
| Front | Explain Intertial (laser) confinement for fusion and its problem |
| Back | A bead of the nuclear fuel is held in place and bombarded by lasers (or ion beams) from all sides. This transfers energy into the fuel and raises the temperature whilst simultaneously confining it as any nucleus attempting to escape is immediatley pushed back by a laser or ion beam. Has the issue that extracting the heat to generate electricty can be difficult, but could work in a pulse based system where pellets are constanly replaced.
