  1. Nuclear Fusion Power The Energy of the Future?

  2. Past, Present, and Future • What is nuclear fusion? • How was it discovered? • What is being done with it today? • What career opportunities are there involving fusion?

  3. What is nuclear fusion? • Stellar nuclear fusion 4H →He • Stellar plasmas have a slightly complicated 3-step fusion process that varies on the size of the star • Nuclear fusion power uses Deuterium and Tritium isotopes of H • T+D →He + n at temperatures of over 100 million K • D is readily available • T is unstable and decays quickly, processed from Lithium

  4. How was it discovered • In 1951, German scientists in Argentina made unsubstantiated claims of producing controlled fusion • Fusion was initially a weapon • Edward Teller championed the idea of the thermonuclear superbomb (Hydrogen bomb) utilizing fusion • Soviet and US research almost 100% devoted to weapons development

  5. ITER • Started internationally the late 1980’s to develop peaceful fusion power • In 2001 designs for the facility were completed • In 2005 Cadarache, France was picked as the build site • Currently the management of the project has been established • Construction is bogged down in international politics • USA left the project in 1999 and rejoined in 2003

  6. ITER goals • Achieve 5-10x energy yield • Begin construction next year • First plasma by 2016 • Testing key technologies and techniques for fusion • Develop Tritium breeding methods from lithium compounds • Will only run at 1/6th of power output level of future power plants

  7. ITER support and opportunity • “$12 billion gamble” • Criticized for being such a large investment for an unproven method • Some alternative energy advocates say the money could be better spent • Funded by USA, China, India, Russia, Korea, and EU • Sign up today: submit your CV

  8. Cold Fusion • In 1989 two scientists claimed they achieved fusion at room temperature • Discredited when results couldn’t be reproduced • Last year, three UCLA physicists (above) developed easily reproducible cold fusion • Too small scale to ever be used as an energy source

  9. Plasma Physics • Gateway to cutting edge fusion work is plasma physics • Top programs • Princeton’s National Plasma Physics Lab • Funded by US Dept of Energy, tied with Princeton’s graduate program • UCLA has a Tokamak fusion reactor • MIT and UT Austin also highly acclaimed

  10. Career options in fusion • Research and Development • Get a PhD in plasma physics and research at one of several international sites • ITER, CERN, PPPL, UCLA • Lobbyist for science • Usually PhD scientists who become politically active • Important on a national and international level to secure funding needed to make breakthroughs
