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.”
