Researchers continue to work on controlling nuclear fission to make a fusion reactor to produce electricity. Besides this, an enormous amount of energy is released which is much greater than the energy of fission reaction. Atoms of Tritium and Deuterium combines under high temperature and pressure to produce a neutron and helium isotope. Safeguards must be used with nuclear fission reactors for this waste and its transportation for storage.ĬONTINUE READING BELOW What is Nuclear Fusion?įusion occurs when two low mass isotopes (mostly isotopes of hydrogen) combines under extreme temperature and pressure. Radioactive wastes are generated as a byproduct of fission reaction whose results take thousands of years to lose their dangerous level. High-speed electrons become projectiles that initiate other fission reactions which are called chain reactions. Produced energy is used to heat water in nuclear reactors and generate electricity. It splits the target nucleus and breaks it down into small isotopes, three high-speed neutrons and a large amount of energy. During fission process, a neutron is accelerated and hits the target nucleus, which in the majority of a nuclear power reactor is Uranium. Neutrons are accelerated and slammed into isotopes which cause fission, break into small particles. Nuclear fission takes place when high-speed particles, neutrons are bombarded on the unstable isotope. Nuclear fission was discovered by German scientists, Lise Meitner, Otto Hahn and Fritz Strassmann. He started experiments in 1939, and after one year Enrico Fermi built a nuclear reactor. The combination of hydrogen nuclei to form helium nuclei, the hydrogen bomb.ĬONTINUE READING BELOW What is Nuclear Fission?Īlbert Einstein’s prediction that mass could be changed into energy made possible of nucleus division. Nuclear fusion is not utilized to produce energy because it cannot be controlled. Nuclear fission is used in nuclear reactors because it can be controlled. It is carried out by heating small nuclei at high temperature. It is occurred by bombarding the heavy nucleus with neutrons.

Very high temperature is required to start nuclear fusion. The high temperature is not required to initiate nuclear fission.

Splitting of a large atom into two or more small atoms is called nuclear fission.įusion of two or more small atoms into one large atom is called nuclear fusion. The difference between nuclear fission and nuclear fusion is that a heavy nucleus splits into two small nuclei in nuclear fission while two heavy nuclei combine to form a heavy nucleus in nuclear fusion. Last year the US National Ignition Facility (NIF), at the Lawrence Livermore National Laboratory in California succeeded in creating fusion by a different method of compressing a plasma using immensely powerful lasers.Īnd in the decades since large government-backed projects like JET, NIF and ITER were conceived small, private fusion ventures have been springing up.Both are nuclear processes by which atoms are changed to produce energy.

It's seen as the full 'reactor-scale' demonstration of the technology that engineers would require to learn how to build a commercial reactor.īut ITER is not the only game in town.

The project is a collaboration between the world's major economies to build a scaled-up version of the JET experiment. It's a major boost for the €20bn (£16.9bn) International Thermonuclear Experimental Reactor (ITER) which is under construction in the south of France.
