  • Preventing Nuclear Terror Mateo O-C And Jacob C
  • Overview • Nuclear Power • Why is it a Grand Challenge? • Pros • Cons • Who uses it? • How is it used? • Future Plans
  • Nuclear Power • Nuclear power is an alternative power source that creates heat through the use of nuclear fission of uranium. This creates electricity through a heat transfer mechanism and/or turbines.
  • Why is it a Grand Challenge? • The makings for a nuclear bomb are not difficult to attain • One of the most dangerous types of weapons in the world • Only a small amount can cause massive destruction • Very difficult to trace and assign blame
  • Pros • Today nuclear energy provides almost 14% of the world's electricity • More than all electricity produced worldwide in 1960. • Over 10,000 hospitals worldwide use radioisotopes in medicine. • There are some 18 million nuclear medicine procedures per year among 311 million people in the US, and in Europe about 10 million among 500 million people. • The use of radiopharmaceuticals in diagnosis is growing at over 10% per year.
  • Pros (Cont.) • Renewable resource • Won’t run out in short term • Doesn’t use fossil fuels • It is a reliable process that can be used for many years. • Small waste amount(Amount of waste would cover a table) • Waste is kept in capsules to ensure the safety of others. • Power plants supply thousands of jobs
  • Cons • “Nuclear terrorism is one of the most serious threats to the security of the United States.” says armscontrolcenter.org’s John Isaacs • In 2010, President Obama hosted the first Nuclear Security Summit in Washington, D.C. aimed at preventing nuclear terrorism. A second Summit was held in Seoul in 2012 and a third is planned for the Netherlands in 2014.
  • Cons (Cont.) • Pollutes radioactive waste • Possibility of radiation leakage or plant meltdown • Very few nuclear power plants across the world • Nuclear reactors are very expensive to purchase and install. • Nuclear power plants will have to be shutdown for maintenance at one point in time.
  • Who uses it? • Scientists and Medical professionals can make nuclear power very useful and helpful. • Many people get the electricity they live off of every day from nuclear power. • Terrorists can easily use this power against us. • Very unstable and dangerous conditions can cause careless people to hurt others.
  • How is it used? • Used to produce electricity that is 20,000 times more than what can be produced from coal • Used to power generators for the City of Cape Town in case of a blackout • The theories of nuclear fission are used in medicines • The idea of splitting atoms has lead to development in treatments for cancer patients
  • Future Plans • Nuclear power emits no greenhouse gases, it’s always on, it doesn't face the price volatility that natural gas does, and it actually has a better safety record than the coal industry. • BUT, nuclear energy also faces many challenges, including sky-high costs, safety concerns, waste disposal and the threat of proliferation.
  • Review • Nuclear Power • Why is it a Grand Challenge? • Pros • Cons • Who uses it? • Future Plans
