The ITER Project, an international project, aims for the realization of fusion generated power

The ITER Project is a highly significant international project. For the first time ever, humankind aims to create and control 500,000 kW of fusion energy through the cooperation of several countries from around the world.
ITER, which means “the way” in Latin, hopes for the way to the realization of fusion energy and the way toward international collaboration for the earth.


The Member Countries and Objectives of the ITER Project

Plans for the construction of an experimental reactor (ITER) through international collaboration of Member countries began in 1985. Subsequently , an international agreement was made between the 7 Members - Japan, the European Union (EU), the United States of America, Russia, China, Korea and India - and the main component of the plans for the construction and operation of an experimental reactor started in 2007.


3 Objectives

The ITER project is building an experimental reactor (ITER) in Cadarache, France with the cooperation of the Member countries and will conduct scientific and technological verifications for the realization of fusion energy. It has 3 main objectives.
① Verification of Fusion Combustion
To demonstrate that fusion energy can be created efficiently for a certain period of time (approximately 400 seconds) using deuterium and tritium as fuel.
② Verification of Reactor Engineering Technologies
To verify the engineering technologies, such as equipment and measures, necessary for fusion energy.
③ Experimentation of extracting fusion energy
Experiments will be conducted to derive heat from fusion energy created within the reactor and to recycle tritium.


● A long term project that will span 35 years

The ITER Project is a long term research and development project that will span 35 years from the construction and operation to the decommissioning of the experimental reactor.

 ◎The ITER schedule



The Experimental Reactor (ITER) Now and Beyond

Site preparation for the experimental reactor (ITER) began in Cadarache in Southern France in January 2007, and construction of the building began in 2010. Assembly of the experimental reactor will start in the latter half of 2015 and construction will finish in mid 2020 when operations will begin. 7 years later in 2027, experiments on fusion energy reactions projected to create 500,000 kW of fusion energy, a first for humankind, is planned to take place.


● Japan plays a crucial role in the construction and operation of ITER

The equipment and measures for the experimental reactor (ITER) are made by collaborating and allotting work among Member countries, but Japan is responsible for the most work involving cutting edge high tech equipment which requires advanced levels of scientific technology. Japan is in charge of the construction of super conductive coils used to control plasma, which were considered the most difficult, as well as remotely operated robots used for maintenance. Japan therefore plays a crucial role in the construction and operation of ITER.

● ITER as a step toward bringing the Demonstration Power Plant (DEMO) to Japan!

Once the Broader Approach (BA) Activities (research and development for the demonstration power plant; the next step after ITER) are complete, Japan aims to have an outlook in place regarding the realization of fusion energy in the mid 21st century.
