What is the fuction of the control rods in a nuclear reactor?
The control rods are used to control the power of the reactor by controlling the nuclear reaction. The control rod will absorb neutrons preventing the neutrons from continuing the fission chain reaction
How is the used fuel from the nuclear reactor stored?
When fuel comes out of the reactor it is considered high level waste and stored in spent fuel pools. After being in the spent fuel pool for 10-20 yrs, the used fuels then moved to dry cask storage.
Identify the energy transformations that take place from the time a Uranium atom is split until electricity is produced?
NE- TE- ME- EE
Describe the 5 stages in the production of electrical energy at a fossil fuel-burning power plant
1. CPE is converted to TE through burnig of fossil fuel
2. TE heats water and products steam
3. Steam spins the turbine
4. The ME of the spinning turbine spin a generator
5. The generator generates an electric current through electromagnetic induction
Why are fossil fuels considered a non-renewable resource?
Fossil fuels are being considered faster than they can be repenished by natural processes
Why is nuclear fusion not currently used as an energy source on Earth?
It has been done in a lab, but right now it is not controllable because of the high temperatures
The information on a smoke detector says that it shoud be returned to the manufacturer and not thrown away in the trash can. Why is this so ?
A radioactive, Americium, is used in smoke dectectors. Radioactive waste needs to be disposed of properly to protect people and the environment
