1. How nuclear energy is used to solve energy scarcity?
Since we are running out of fossil fuels, and our increasing population, nuclear energy might be our only solution to be able to produce energy in town. However, there are other solutions, such as, wind energy and solar energy but that wouldn't be enough to produce the energy to the whole town. Therefore, nuclear energy can be the choice since it produces lot of energy. But, this can be the most dangerous source because of nuclear waste.

2. How is nuclear energy produced?
Nuclear energy is been produced by storing uranium atom into the Nuclear rods. When the uranium is hit by the neutron, it breaks down into Krypton and Barium. When the uranium atom breaks, a chain reaction starts. At the very end this will generate a lot of heat.

a) What is nuclear fission? Nuclear fission is when auranium atom is been split by the neutron, that breaks down into Krypton and Barium. Then the Krypton and Barium breaks down into more uranium atoms in the end. This action will go on for a long time, and this is also called the chain reaction. Uranium can be only broken down depending on how much atoms there are around it.

b) How is nuclear energy used to generate electricity? When the nuclear rods produce heat, it increase the steam pressure which makes the turbine to go on that will at the end produce the energy.



3. What are the advantages and limitations of nuclear energy? Advantages: Disadvantages:
 * Replace fossil fuel.
 * Generates a lot of electricity.
 * Radiation last for a long time
 * Nuclear Waste
 * Nuclear explosions produce radiation. The nuclear radiation harms the cell of the body which can make people can sick or even kill them.

4. How does nuclear radiation affect the environment?
Radiation is a bad impact to the animals, humans and environments. The chernobyl accident is a good example of a negative impact of radiation to the environment. Although it's very harmful, it will eventually go off.This can cause birth defects on Humans.The water used for cooling down, will be pumped up from a lake or sea, and then it will go back, but the temperature is going to be much warmer. This can cause death to fish, since they're probably not used to the warm temperature.

5. How does nuclear radiation affect health?
Nuclear radiation affects us by making our cells brake down and our DNA breaking the Proteins down.

**Notes May 23rd 2012:**
Weapons - grade uranium - Enriched Plutonium - 210 - Mass number 94 <--- atomic number - protons + neutrons PU 94 244<- mass number Plutonium - 244 Protons

Electrons - negative charged ↘ because they attract to each other protons - positive charged ↗

neutron neutral

Electric current = Electrons

Sub - particles → Protons 1 → neutrons → electrons Nuclear energy essay Atomic number = Number of protons If it's really light it's usually a gas (for e.g. Helium) Cl ² - gas - 17 Br ² - 35 - Liquid Plutonium - 210 is an isotope of plutonium - 244 Same person but one's lighter and the other is heavier. Different number of neutrons. All plutonium will have 94 protons. 210 - 94 = 116 number of neutrons Mass number - Atomic number = number of neutrons
