PPT-Nuclear power 8.4.1 Describe how neutrons produced in a fission reaction may be used to

842 Distinguish between controlled nuclear and uncontrolled nuclear fission 843 Describe what is meant by fuel enrichment Topic 8 Energy power climate change 84 Nonfossil fuel power production. Special Topic 2014. Exam Craft mock 2014. Define the term Nuclear Fusion:. It is the process the nucleus of an atom (uranium or plutonium) is bombarded with neutrons. This splits the nucleus (fission) realising large amounts of energy in the form of heat.. 8.1 Nuclear Fission . - release of energy due to splitting of heavy elements into two parts. . (. atomic bomb . and . nuclear reactors. ). 8.2 Nuclear Fusion . - fusion of light nuclei into heavier with release of energy. The Nucleus. Protons – . 1.672 . × 10. 27. kg. Neutrons – 1.675 . × 10. 27. kg. isotopes. Strong Nuclear Force. Holds the protons and neutrons together.. Third Fundamental Force (after gravity and the electromagnetic forces). . Stations. . Nuclear power station. s. Introduction. . What’s in a Nucleus. The nucleus of an atom is made up of . protons. and neutrons. each is about 2000 times the mass of the electron, and thus constitutes the vast majority of the mass of a neutral atom (equal number of protons and electrons). Dubna. , Russia. Avazbek NASIROV. Joint Institute for Nuclear Research. Contents of talk. Short information about synthesis of superheavy elements . . in heavy ion collisions.. 2. Significance of nuclear reactions: . How it works?. Just as conventional power-stations generate electricity by harnessing the . thermal energy . released from .  . burning fossil fuels, . nuclear reactors convert the thermal energy released from . Dubna. , Russia. Avazbek NASIROV. Joint Institute for Nuclear Research. Contents of talk. Short information about synthesis of superheavy elements . . in heavy ion collisions.. 2. Significance of nuclear reactions: . Nuclear power plant. 2. NUCLEAR FUEL. Nuclear . fuel is any material that can be consumed to derive nuclear energy. The most common type of nuclear fuel is fissile elements that can be made to undergo nuclear fission chain reactions in a nuclear reactor . ~bombs and nuclear power. Nuclear fission. ~the separating of a nucleus of an atom.. This is the process used by nuclear power stations (when it is kept under control).. It is also the process of an atom bomb (when it is allowed to run uncontrolled). . Heavy Elements can reduce. energy (i.e. increase binding. energy per nucleon) by. splitting roughly in half.. U 235 fission fragment distribution. Excess Neutrons. 235. 92. U + n . →. . 86. 38. Nuclear Fission. We convert mass into energy by breaking large atoms (usually Uranium) into smaller atoms. Note the increases in binding energy per nucleon.. A slow moving neutron induces fission in Uranium 235. Fission. Fusion. Transmutation. Skills to Master. HW . 20e. Read. OER . 20.4. Excellent resource – lots of extra practice and answers at:. https://. saylordotorg.github.io/text_general-chemistry-principles-patterns-and-applications-v1.0/s24-nuclear-chemistry.html. Gamma radiation. In gamma radiation no particle is released, just a “packet” of energy.. Photon- “packet” of energy.. When an atom has too much energy, it is . excited. , it’s electrons are in higher energy levels.. Enormous Energies. Nuclear Fission. Take a large atom and impact the nucleus with a particle. . Split the atom releasing high energy, more high energy neutrons, and two daughter nuclides.. Fission occurs only rarely in nature. Alpha decay is much more common..
