  1. Future NukesChapter 28 Carrie Reed

  2. Electricity • Electricity-1 Constant: Growing demand • 1950’s demand up 9% per year • 2005 demand grows 1.1% • 2009 demand drops 5% • 2030 demand up 34% compared to 2007

  3. Modular Reactors • Cost only a fraction of larger reactors • Used as single or multiple units • Buy many small reactors and add as needed • Can be manufactured in a central location • Decreases cost • Buried below ground, more resistant to weather and terrorism

  4. Modular Reactors • Toshiba • Revealed in 2006 • 10 mega watt • One of the first • Babcock & Wilcox • Revealed in 2009 • 125 mega watt Figure 1- Babcock & Wilcox Modular Reactor

  5. Thorium (Th) • Close to Uranium on Periodic Table • Doesn’t produce Plutonium • U.S. holds ~20% of world’s supply • ~4X more abundant • Easier to mine Figure 2- Thorium

  6. Pebble-Bed • Uses fuel pellets • Fuel cycle is safer • Reduces possibility of nefarious acts with Plutonium

  7. In 2005 World Energy Outlook, the International Energy Agency declared that “nuclear technology is the only large-scale, base load electricity-generation technology with a near-zero carbon footprint.”
