2. The Energy Story - Chapter 13: Nuclear Energy - Fission And Fusion The Energy Story is a general introduction to energy. Chapters explore renewable energy, fossil fuels, electricity, circuits and many other things. http://www.energyquest.ca.gov/story/chapter13.html

Table of Content Introduction Chapter Energy - What Is It? Chapter ... Conclusion Chapter 13: Another major form of energy is nuclear energy, the energy that is trapped inside each atom. One of the laws of the universe is that matter and energy can't be created nor destroyed. But they can be changed in form. Matter can be changed into energy. The world's most famous scientist, Albert Einstein , created the mathematical formula that explains this. It is: This equation says: E [energy] equals m [mass] times c c stands for the velocity or the speed of light. c means c times c c -squared.] You can listen to Einstein's voice explaining this at: www.aip.org/history/einstein/voice1.htm Please note that some web browser software may not show an exponent (raising something to a power, a mathematical expression) on the Internet. Normally c -squared is shown with a smaller " " placed above and to the right of the c Scientists used Einstein's famous equation as the key to unlock atomic energy and also create atomic bombs. The ancient Greeks said the smallest part of nature is an atom. But they did not know 2,000 years ago about nature's even smaller parts. As we learned in chapter 2 , atoms are made up of smaller particles a nucleus of protons and neutrons, surrounded by electrons which swirl around the nucleus much like the earth revolves around the sun.

3. Topic 10 We will look at the processes that release nuclear energy. Fission. Very large nuclei tend to be rather unstable. This means that they are radioactive. http://www.antonine-education.co.uk/Physics_GCSE/Unit_2/Topic_10/topic_10.htm

Topic 10 What are nuclear fusion and nuclear fission? I n the exam you need to know how: to sketch a labelled diagram to illustrate how a chain reaction may occur. In the exam you need to know about: There are two fissionable substances in common use in nuclear reactors, uranium 235 and plutonium 239. Nuclear fission is the splitting of an atomic nucleus. For fission to occur the uranium 235 or plutonium 239 nucleus must first absorb a neutron. The nucleus undergoing fission splits into two smaller nuclei and 2 or 3 neutrons and energy is released. The neutrons may go on to start a chain reaction. Nuclear fusion is the joining of two atomic nuclei to form a larger one. Nuclear fusion is the process by which energy is released in stars. Key Words Nuclear Energy Fission Fusion Nuclear Energy Sixty years ago the power of nuclear energy was demonstrated to the world. Little Boy, a free-fall atomic bomb was dropped on Hiroshima in August 1945. A few days later an aerial mine, Fat Man, was detonated over Nagasaki. The destruction and carnage caused by these bombs is well known. The energy released was due to the conversion of 20 grams of nuclear material to heat. The conversion of nuclear energy to heat is at the heart of nuclear energy. Scientists have learned to control the process so that instead of an explosion, a steady heat source is achieved. A

Nuclear Energy The sun and stars are seemingly inexhaustible sources of energy. That energy is the result of nuclear reactions, in which matter is converted to energy. We have been able to harness that mechanism and regularly use it to generate power. Presently, nuclear energy provides for approximately 16% of the world's electricity. Unlike the stars, the nuclear reactors that we have today work on the principle of nuclear fission. Scientists are working like madmen to make fusion reactors which have the potential of providing more energy with fewer disadvantages than fission reactors. Production Changes can occur in the structure of the nuclei of atoms. These changes are called nuclear reactions . Energy created in a nuclear reaction is called nuclear energy , or atomic energy Nuclear energy is produced naturally and in man-made operations under human control. Naturally: Some nuclear energy is produced naturally. For example, the Sun and other stars make heat and light by nuclear reactions. Man-Made: Nuclear energy can be man-made too. Machines called

Chapter Head Home Table of Contents Glossary ... Appendix Nuclear Fission Energy Fig. 14-1. Fission of U after absorption of a thermal neutron. The relevant nuclear reactions can be written as follows: U + n fission products + neutrons + energy (~200 MeV) (1) U + n U + gamma rays (2) U Np Pu (a series of beta decays). (3) An integer number of neutrons, for example, either two, three or four, are emitted in the reactions leading to different pairs of fission products described in reaction (1). The average number is 2.43. Some of the neutrons in reaction (1) can be used to induce fission in another U nucleus, thus continuing a controlled, self-perpetuating nuclear chain reaction. Some fraction of the remaining neutrons from reaction (1) are utilized in reaction (2) to produce Pu. The rest are absorbed in other nuclei without further effect. The isotope Th, although not fissionable with thermal neutrons, is a possible energy source because it absorbs thermal neutrons to produce long-lived U, which also undergoes thermal neutron fission with a high probability. Thus the "big three" readily fissionable nuclei are: U

Modular Pebble Bed Reactor The research objective of our project is to establish the conceptual design for an innovative modular pebble bed reactor (MPBR) that is cooled by helium and generates electricity using helium gas turbines. The plant would be rated at 120 MWe with a modular design that will allow factory manufacture of most modules, making the plant economically competitive with natural gas, combined-cycle plants. Our overall objective is to participate in the design, construction, and operation of the Next Generation Nuclear Plant (NGNP) to be built in the next decade at the Idaho National Laboratory (this plant would also be a test bed for hydrogen production). Areas of research include: coated fuel particle design, safety analysis, core optimization, modularity principles of factory fabrication, high temperature intermediate heat exchanger design and overall design optimization. If successful, the modular approach to design and construction will offer enhanced safety and economic competitiveness that could revolutionize production of nuclear-generated electricity.
