Index IIntroduction WWhat is ITER? HHow to work? AAdvantages & Disadvantages LLatest News

Ⅰ. Introduction IITER -F-Future Energy -L-Like a artificial Sun IIdea from <Sharing Science> 10, 2006 (an interview with Norbert Holtkamp, ITER Director-General Kanme Ikeda)

Ⅱ. What is ITER ? AAs a fusion future energy IInternational Thermonuclear Experimental Reactor IIter : Latin meaning ‘the way’ IIdea from - at the Geneva Summit, in 1985 OObject ddemonstrate the scientific and technological feasibility of fusion energy for peaceful purposes ddeveloping a viable fusion power reactor

Ⅲ. How it works FFusion : Small nuclei can be combined (Deuterium) (neutron) (Tritium)

ccf. Fission aa large nucleus is split apart NNeutron + 235U → fission fragment + neutron + E

WWhy is fusion better? tthe light nuclei are plentiful and easy to obtain - Deutrium : 0.03g/1L sea water → Same energy for 300L gasoline ( capability for 456km * 6 trip) - Tritium : convert Li ’s nuclei, Li reserves - 15 million years to use CCreate 10 times more energy

SSafe and environmentally friendly - product He is not radioactive - no greenhouse gases - low radio toxicity waste product

Ⅳ. Problems TTechnology - constructing the device, Tokamak : a machine producing a torodial (doughnut-shaped) magnetic field for confining a plasma. * plasma : the forth state. An ionized gas co- nsisting of positive ions and free electrons in proportions reslting in more or less no overall electric charge, typically at low pressures or at very high temperatures an cutaway image of the ITER fusion divice ▶

Ⅴ. Schedule & Latest News  E.U.(built in France), Korea, India, China, Japan, Russia, U.S.  Schedule  General intent : in 2016, ITER begin operation  It takes 25~30 yrs to common use  Total budget = about ＄ 6.5 billion

Ⅴ. Schedule & Latest News  Comparing : ITER is quite efficient (fusion) ( atomic energy) (LNG) (petroleum) (soft coal)
