Introduction What is ITER? How to work? Advantages & Disadvantages Latest News

Ⅰ. Introduction

ITER- Future Energy- Like a artificial Sun

Idea from <Sharing Science> 10, 2006 (an interview with Norbert Holtkamp, ITER Direct

or-General Kanme Ikeda)

Ⅱ. What is ITER ?

As a fusion future energy International Thermonuclear Experimental Reactor Iter : Latin meaning ‘the way’

Idea from - at the Geneva Summit, in 1985

Object demonstrate the scientific and technological feasibility of fusion

energy for peaceful purposes developing a viable fusion power reactor

Ⅲ. How it works

Fusion : Small nuclei can be combined (Deuterium) (neutron)

(Tritium)

Ⅲ. How it works

cf. Fission a large nucleus is split apart

Neutron + 235U → fission fragment + neutron + E

Ⅲ. How it works

Why is fusion better? 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

Create 10 times more energy

Ⅲ. How it works

Safe and environmentally friendly - product He is not radioactive

- no greenhouse gases - low radio toxicity waste product

Ⅳ. Problems

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

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)
