Facts and ideas about Nuclear Power

                            
Nuclear Power Prevents More Deaths Than It Causes (Source).  However, 47 people officially died due to the Chernobyl (Ukraine) meltdown. New research argues that the death toll is actually 985,000. Why is there such a difference in the two numbers?  Additionally, no one has died due to radiation from the Fukushima (Japan) nuclear disaster...yet, but how many will that be? (Source)


One uranium fuel pellet creates as much energy as one ton of coal or 17,000 cubic feet of natural gas (Source).   However,  Every 18 to 24 months, a power plant must shut down to remove its spent uranium fuel, which has become radioactive waste (Source) and United States power plants produce 2,000 metric tons of radioactive waste every year (Source).


Solar panels convert 22% of their available energy into electrical power, compared to nuclear energy’s 90% (Source and Source).100 nuclear facilities in 31 states provide nearly 20 percent of all U.S. electricity (Source).  However, coal amounts for 45% of the electricity generated in the U.S. (Source) and clean coal technology now exists which makes it much safer for the environment (source). One of the leading ideas is called carbon capture- trapping CO2 and turning it into a solid, then burying it (source).  However, some argue that clean coal is a myth (source and  source).

Nuclear Power: Pros and Cons

After completing the domino chain reaction activity, Read some of the following articles about nuclear power:

http://tiki.oneworld.net/energy/energy7.html  (basics of nuclear power)

http://science.howstuffworks.com/nuclear-power.htm  (how nuclear power works)

http://online.wsj.com/articles/SB121432182593500119  (more advanced pro and con list)

Then, on page 26 in your notebook, create a T-chart like this one  with some of the pros and cons about using it.  The more you find now, the better off you will be for a future assignment.
