What exactly is Nuclear Fission? | -This is a Nuclear Reaction, that Release Energy via Large and Unstable Nuclei by Splitting them in 2 |
How can Nuclear Fission happen? | -Spontaneously: Simply just Happens
-Absorbing a Neutron- making it Unstable and Splitting |
So what are the Products, and Energy Transfers from Fission? | -2 Smaller Nuclei is made, and also a few Neutrons are Give out
-Energy can be Transferred to the Kinetic Energy Stores of the Products, or Carried Away by the Gamma Radiation |
How can a Chain Reaction happen? | -If a Unstable Nuclei splits up, it can give Neutrons out, which can be Absorbed by Other Nuclei making them Unstable...
-This is a Chain Reaction, and will Stop when the Nuclei is Stable Enough or there isn't any Collisons |
How do Nuclear Power Stations Profit from Fission? | -Using Uranium or Plutonium as Reactants for Chain Reactions, it can create a Lot of Energy
-This energy is Used to Heat Water, making Steam
-This Steam drives the Steam Turbine that's Connected to a Electricity Generator |
What are the Advantages and Disadvantages of Nuclear Power Stations? | A: They are Renewable [They aren't really, but there's so much Reactants that its safe to say so] and also Nuclear Fuel is Cheap
D: They make Nuclear Waste which is Very Reactive and has Long Half Lives, making them a Pain to Dispose of.
The cost of the actual Power Station, and the Dismantling, is very Expensive and Time Consuming
A Repeat of Chernobyl may cause a Massive National Breakdown |
What is Nuclear Fusion? Give an Example | -This is simply when 2 Nuclei, usually Small, join to make a Large Nucleus.
-2 Hydrogen Nuclei join to make a Helium Nucleus |
How much Energy can Fusion give off? Where is it seen? Why can Fusion make that much Energy? | -Fusion gives Even More Energy than Fission
-Stars use Fusion to Fight the Gravity
-This is because the Reactants [2 Hydrogen Nuclei eg] always will have more Mass than the Product [Helium Nuclei]
-This Redundant Mass is turned into Energy, and given off |
What are the Advantages and Disadvantages of Nuclear Fission? | A: No Nuclear Waste is made, and Fuel can be Extremely Easy to Get [Hydrogen]
D: No Reactors have Started making Electricity yet, so its Unknown if it can ever Work.
The Conditions needed [10 Million Degrees and Stupidly High Pressures] needs a Strong Magnetic Field, which is Very Expensive |
