  1. Star Power A Nuclear Fusion Story

  2. Nuclear Fusion • The smashing together of two nuclei to produce tremendous energy • The reaction occurring in the Sun • Very little radioactive remnants compared to fission.

  3. First Uses • The first application of fusion technology was in thermonuclear weapons. • The next plan was to apply the technology to power creation • I will focus on the Toroidal methods

  4. Sober Lessons • Immediately after World War II, work began on the design of the first fusion reactor • Taking an early lead, the British built ZETA, the Zero Energy Toroidal Assembly • They were successful, however the system design used more energy than it outputted • Note: A Toroidal shape is like the inside of a tire

  5. Soviet Extraordinaire • In the late 1950’s through the ‘60’s, the Soviets devised and built a TOKAMAK style reactor. • By the ’70’s, 17 tokamaks had been built and there are currently over 100 in operation

  6. Tokamak? Stellarators? • The purpose behind Tokamaks and Stellarators is to create a spiraling magnetic (helical) field to stabilize plasma • Tokamaks achieve this by inductively driving a current into the plasma producing a helical field • It is advantageous because it can use that current to heat and stabilize the plasma • The Stellarator was originally conceived in Princeton University • It produces a helical field by an external current carrying wire • It is advantageous because it can be operated at a steady state. • So far, the best result are produced by the Tokamak method

  7. That’s one bad Tokamak • The TFTR, Tokamak Fusion Test Reactor, in the Princeton Plasma Physics Laboratory , operational in 1976,has set many world records • Some Records set highest plasma temperature achieved at 510 million degrees highest controlled power output at 10.7 million watts the list goes on…

  8. JET – Joint European Torus • JET begins operation in the United Kingdom in 1978, it is the largest operational Tokamak • As the largest Tokamak, it is the technology demonstrator for the ITER, the future • It has also set many world records 22 megawatts from a single pulse 16 megawatts of power output (surpassing TFTR)

  9. The Future • ITER – A joint collaboration between Europe, Japan, Russia, and Canada • It is to be a Tokamak style reactor three times as large as JET. • It will be the result of over 50 years of research and design • Its mission is to show the feasibility of Fusion power creation as a future power source.

  10. Support ITER CANADA • Currently the United States is not funding the ITER project because of the possibility of it being based in Japan • If it were to be based in Canada, the US would reconsider funding the project • Web Site: http://www.itercanada.com/ • Also, I could work there!!!
