The road to fusion power

Before watching the video make sure you can handle the following fusion-related words and their definitions. Match the word with its correct definition source: fusion The merging of two light atomic nuclei into a heavier nucleus, with a resultant loss in the combined mass and a massive release of energy. fission The process by which a neutron strikes a nucleus and splits it into fragments; during the process of nuclear fission, neutrons are released at high speed, and heat and radiation are released. isotope One of several versions of the same element, possessing different numbers of neutrons but the same number of protons in their nuclei. ionization The removing or adding of an electron to a neutral atom, thereby creating an ion. ion (pronounced "aieun") An atom which has become charged as a result of gaining or losing one or more orbiting electrons. A completely ionized atom is one that is stripped of all its electrons. KSTAR The KSTAR, or Korea Superconducting Tokamak Advanced Research, is a magnetic fusion device at the National Fusion Research Institute in Daejon, South Korea. superconductivity The flow of electric current without resistance in certain metals and alloys at temperatures near absolute zero. Tokamak A fusion device for containing a plasma inside a torus chamber through the use of two magnetic fields--one created by electric coils around the torus, the other created by intense electric current in the plasma itself. Watch the video extracted from the bbc website and do the following activities. What temperature has the record-breaking reaction reached? 50 million degrees centigrade 140 million degrees centigrade 150 million degrees centrigrade How hotter is it compared to the temperature of the heart of the sun? Where is the world's most powerful plant, JET FUSION, located? In Culham, Oxfordshire, UK In China In Southern France What has the team there succeeded in creating? Why is creating mini stars one of 'the greatest challenges humanity has ever faced"? How long does the key part of the reaction last? 5 minutes 25 seconds 5 seconds The following statement is true: Fusion physicist Athina Kappatou is very optimistic about commercial fusion.Justify it by quoting from the video. According to the video why is fusion energy one of the solutions to the climate crisis? Give a structured account of the video in FRENCH. Make sure you organize your account.
