For a few weeks now, the program has been broadcast on the public broadcaster every weekday evening around 10.30 p.m. 'The World Learns Onbroadcast. In 12 minutes, a scientific researcher is given the opportunity to tell the general public about his or her research. In the broadcast of January 15th used to be Willem Haverkort guest and talked about his contribution to the nuclear fusion reactor under construction in the south of France.
It ITER project is an international partnership that aims to build a working prototype of a nuclear fusion reactor: ITER. This involves demonstrating the scientific and technical feasibility of nuclear fusion as an energy source. Currently, the European Union, the United States, Japan, China, India, South Korea and Russia are participating in the project, which is considered the largest scientific experiment in the world. This project started in the mid-1980s and in 2005 it was decided to build ITER in Cadarache, France.
The best-known example of an energy source based on nuclear fusion is the sun. Previously this site is one article published that explains how nuclear fusion works using the sun and what is considered difficult in this article. And yet that is the purpose of ITER: to mimic the sun on Earth.
The biggest challenge here is to control the extremely high temperatures that arise as a result of the fusion of the atomic nuclei. The temperature that the ITER researchers are focusing on is 150 million degrees Celsius. A temperature that is about 10 times as warm as the center of the sun. No material can withstand such high temperatures. Yet there is a solution: magnetic fields. Haverkort is researching how it is possible to use magnetic fields to create the plasmathat arises during the process. Namely, it is the plasma that reaches such high temperatures and has to be contained in order not to reach the reactor wall.
The goal is that by 2030 there will be a working device in the hope that other countries will follow the example of ITER. If it is possible to get a working prototype of a nuclear fusion reactor, this will mean a very important breakthrough in the search for new suitable energy sources to replace the current existing ones.
