Transcript of Nuclear Power

Yes. Canada should use nuclear power. Ramifications Decision What we recommend to the Minister ~Some problems may be finding a perfect place for the nuclear plants to be since Canada is a growing country with new immigrants.
~It would mean further land expansion for homes, so a place for the nuclear plants could be difficult to find.
~Another issue may be employing people to watch for leaks and problems with the nuclear reactors may have to risk themselves of being so close to power plants and have health issues pertaining to the dangerous radio-active materials in the nuclear power plants.
~If we only add a couple of nuclear power plants, we'll need another source of energy to power the rest of the cities that cannot be powered by nuclear due to the few plants put in place.
~ If there ever were an earthquake, the radiation that's been stored underground would leak out and this could be risky Energy - Nuclear Power Should more nuclear reactors be built to increase electrical power in Canada? Reasons? Firstly, nuclear power plants
do not emit any pollution. Using nuclear energy to power the country instead
of coal can save an additional 90 million tonnes of CO2 from escaping into the atmosphere. That's about 12% of Canada's total greenhouse emissions. It is cheaper than fossil fuel. How is it cheaper? Nuclear Power in Ontario has a 35% cost advantage over fossil fuel. Makes contribution to society/economy Nuclear industries generate revenues (taxes) of around $6.6 billion per year No. Canada should not use nuclear energy for electrical power. REASONS? Nuclear produces waste that has no where to go. In 2000, Canada had 35,000 tonnes of highly radioactive nuclear waste and no place to dispose the waste so it does not harm the land or cause health issues. Nuclear plants could leak hazardous material Example would be the Pickering reactor #4 had a
leak in April, 1996 that released tritium into Lake Ontario. Tritium is an isotope/form of hydrogen and if exposed,
whether through digestion, absorbed through skin, or inhaled, it can cause health risks. It is very costly Plant reconstruction in Ontario, Darlington was budgeted at $3.4 billion but ended up costing $15 billion. http://nuclearsafety.gc.ca/eng/readingroom/tritium/tritium_studies_faq.cfm ~Nuclear reactors have both positive and negative consequences.
~A way to solve this could be adding a few nuclear reactors to different areas in Canada so that there would still be electricity to generate the city.
~ By adding just a couple, not as much radio-active material will be released instead of adding several plants.
~These power plants can be placed in areas where it is close enough to bring electricity to cities but far enough not to disturb anyone or cause health issues.
~By having more employees to make sure the plants don't have leaks can bring up the hiring rate as well as ensure safety. if implemented http://www.nuclearfaq.ca/cnf_sectionA.htm#c

(Ex. Thermal Electricity) Nuclear reactors have a risk of having a 'meltdown' http://library.thinkquest.org/3471/nuclear_energy.html http://www.thestar.com/news/canada/article/953132--canada-s-nuclear-power-under-scrutiny-amid-japan-meltdown-fears http://davidsuzuki.org/blogs/docs-talk/2011/01/a-few-good-reasons-why-we-should-abandon-nuclear-energy-for-good/ http://www.cna.ca/wp-content/uploads/Clean-Air3.pdf Background of Nuclear One ton of uranium (Nuclear reactors' fuel) produces more energy than 7 millions tonnes of coal. A power surge and partial loss of coolant led to damage in 1952 at the Chalk River nuclear site. It was the world's first major nuclear reactor disaster, and it resulted in 4.5 tonnes of radioactive water collecting in the cellar of the building. http://www.cbc.ca/news/canada/story/2012/01/09/f-canada-nuclear-reactors.html Quebec's only nuclear power reactor was shut down in Dec 28, 2012 although dismantling it would take 50 years and $1.8 billion. http://www.cbc.ca/news/canada/montreal/story/2012/10/03/montreal-gentilly-2-shutdown-cost-hydro-quebec.html http://www.thecanadianencyclopedia.com/articles/coal THANK YOU ^.^ =) Bibliography http://www.brucepower.com/ About 15% of Canada's electricity
come from nuclear. The first controllable nuclear reactor was the ZEEP
research reactor built in 1945 in Chalk River, Ontario. Nuclear energy is generated by using Uranium which is a metal that is mined from various parts of the world. The difference between Nuclear energy and other thermal energy is the source of heat Radiation could last for 25,000 years and be active until then The lifecycle of a Vattenfall nuclear plant including mining, milling, enrichment, plant construction, operating, decommissioning and waste disposal emits 3.3 grams per KW-Hr (kilowatts per hour) compared to the output of Natural gas which is 400 grams per KW-Hr One kilogram of natural uranium will produce about 20,000 times as much energy as the same amount of coal. very portable and trade-able commodity product. The Canadian nuclear industry employs about 21,000
canadians directly, 10,000 indirectly, and 40,00 that help with providing the services and supplies It also has exports of more than $1 billion a year from the uranium produced and the goods/services http://www.cna.ca/why_nuclear/economic_benefits/ Stake holders ~Canada is trying to find a place to place the used nuclear bundles of radiation that will remain for 200,000 years. ~Since 2002, the federal government passed a law
for energy companies to find a place for the used used nuclear bundles called " Nuclear Waste Managment Organization. ~Strategy: Finding town to place it 500m deep where about 4 million are going to be until nuclear reactors retire. http://www6.carleton.ca/cctc/ccms/wp-content/ccms-files/Economics-of-Nuclear-Power.pdf WACC - Weighted Average Cost of Capital ~ The used nuclear bundles can be placed underground so the radiation will not have a large impact to the surrounding homes ~A meltdown is when the fission reaction goes out of control, leading to a nuclear explosion causing emissions of great amounts of radiation.
~In 2011, an 8.9 magnitude earthquake struck Japan causing them a meltdown; Canada's nuclear regulators insists that the nuclear sites in Ontario, New Brunswick and Quebec are prepared to handle the natural disasters. DID YOu put it already ~Countries like Germany have announced they will close all their nucelar plants by 2022.

~ German Chancellor Angela Merkel believes her country can replace the 23% of power that nuclear power already provides in Germany by up-scaling renewables such as wind and solar. http://www.energybc.ca/profiles/nuclear.html By: Vivien, Mathinesh, Salman, Maya
