Thus there is tendency to seek alternative sources of energy. The discovery that energy can be liberated by the nuclear fission of materials like uranium (U), Plutonium (Pu), has opened up a new source of power of great importance. The heat produced due to fission of U and Pu is used to heat water to generate steam which is used for running turbogenerator.\r\n\r\nIt has been found that one kilogram of U can produce as much energy as can be produced by burning 4500 tonnes of high grade coal. This shows that nuclear energy can be successfully employed for producing low cost energy in abundance as required by the expanding and industrializing population of future.\r\n\r\nSome of the factors which go in favor of nuclear energy are as follows:\r\n1. Hydro electric power is of storage type and is largely dependent of monsoons. The systems getting power from such plants have to shed load during the period of low rainfall.\r\n2. Oil is mainly needed for transport, fertilizers and petrochemicals and thus cannot be used in large quantities for power generation.\r\n3. Coal is available only in some parts of the country and transportation of coals requires big investments.\r\n4. Nuclear power is partially independent of geographical factors, the only requirement being there should be reasonably good supply of water. Fuel transportation networks and larger storage facilities are not needed and nuclear power plant is a clean source of power which does not pollute the air if radioactive hazards are effectively prevented.\r\n5. Large quantity of energy is released with consumption of only a small amount of fuel.\r\n\r\nNuclear fission\r\nThe fuel inside the reactor is a metal called uranium. Uranium exists as an isotope in the form of U235, U234 and U238. Out of these isotopes U235 is more unstable. When a neutron is captured by a nucleus of an atom of U235, it splits up roughly into two equal fragments and about 2.5 neutrons are released and a large amount of energy (nearly 200 million electron volts MeV) is produced. This is called fission process. The neutrons so produced are very moving neutrons and can be made to fission other nuclei of U235 thus enabling a chain reaction to take place. When a large number of fission occurs, enormous amount of heat is produced. The following fig. shows the chain reaction\r\n\r\n nuclear fussion\r\n\r\nIt may be observed from the fig. that 2.5 neutrons are released in fission of each nucleus of U235, out of these one neutron is used to sustain the chain reaction, 0.9 neutrons is absorbed by U238 and becomes Pu239. The remaining 0.6 neutrons escape from the reactor. Moderators are provided to slow down the neutrons from the high velocities but not to absorb them. The moderators which are commonly used are ordinary water and Heavy water.\r\n\r\n Main components of a nuclear power plant\r\n\r\nThe main components of a nuclear power plant are\r\n\r\n\u2022 Nuclear fuel\r\n\u2022 Nuclear reactor\r\n\u2022 Steam generator\r\n\u2022 Moderator\r\n\u2022 Control rods\r\n\u2022 Reflector\r\n\u2022 Turbine\r\n\u2022 Condenser\r\n\u2022 Shielding\r\n\r\nNuclear Fuel: Fuel of a nuclear reactor should be fissionable material which can be defined as an element or isotope whose nuclei can be caused to undergo nuclear fission by nuclear bombardment and to produce a fission chain reaction. It can be one or all of the following U235, U233 and Pu239\r\n\r\nNuclear reactor: A nuclear reactor may be regarded as a substitute for the boiler furnace of a steam power plant. Heat is produced in the reactor due to nuclear fission of the fuel. During the fission process, the large amount of heat is liberated. This large amount of heat is absorbed by the coolant and it is circulated through the core.\r\n\r\nThe various types of reactors used in nuclear power plant is\r\n1. Boiling water reactor-\u00a0\r\n2. Pressurised water reactor\r\n3. Fast breeder reactor\r\n\r\nSteam generator: The heat liberated in the reactor is taken up by the coolant circulating through the core. The purpose of the coolant is to transfer the heat generated in the reactor core and use it for steam generation. Ordinary water or heavy water is a common coolant.\r\n\r\nRead more :Introduction to Boilers | Classification Of Boilers\r\n\r\nModerator: It is used to reduce the kinetic energy of fast neutrons into slow neutrons and to increase the probability of chain reaction. Graphite, heavy water and beryllium are generally used as moderator. \r\n\r\nA moderator should possess the following properties:\r\n1. It should have high thermal conductivity\r\n2. It should be available in large quantities in pure form\r\n3. It should have high melting point in case of solid moderators and low melting point in case of liquid moderators. Solid moderators should also possess good strength and machinability.\r\n4. It should provide good resistance to corrosion\r\n5. It should be stable under heat and radiation\r\n6. It should be able to slow down neutrons\r\n\r\nControl rods: They regulate the rate of a chain reaction. They are made of boron, cadmium or other elements which absorb neutrons. Control rods should posses the following properties:\r\n1. They should have adequate heat transfer properties\r\n2. They should be stable under heat and radiation\r\n3. They should be corrosion resistant\r\n4. They should be sufficient strong and should be able to shut down the reactor almost instantly under all conditions.\r\n5. They should have sufficient cross sectional area for the absorption.\r\n\r\nReflector: The neutrons produced during the fission process will be partly absorbed by the fuel rods, moderator, coolant or structural material etc. Neutrons left unabsorbed will try to leave the reactor core and will be lost. Such loss is minimized by surrounding the reactor core by a material called reflector which will send the neutrons back into the core. The returned neutrons can then cause more fission and improve the neutrons economy of the reactor. Generally the reflector is made up of graphite and beryllium.\r\n\r\nTurbine: The steam produced in the steam generator is passed to the turbine. Work is done by the expansion of stem in the turbine.\r\n\r\nCondenser: The exhaust steam from the turbine flows to the condenser where cooling water is circulated. The exhaust steam is condensed to water in the condenser by cooling. The condensate is pumped again into the steam generator by the feed pump.\r\n\r\nShielding: The reactor is a source of intense radioactivity. These radiations are very harmful and shielding is provided to absorb the radioactive rays. A thick concrete shielding and a pressure vessel are provided to prevent the radiations escaped to atmosphere.\r\n\r\nWorking of a Nuclear Power plant\r\nThe reactor of a nuclear power plant is similar to the furnace of steam power plant. The heat liberated in the reactor due to the nuclear fission of the fuel is taken up by the coolant circulating through the reactor core. Hot coolant leaves the reactor at top and then flows through the tubes of steam generator (boiler) and passes on its heat to the feed water. The steam produced is passed through the turbine and after work has been done by expansion of steam in the turbine, steam leaves the turbine and flows to condenser. Pumps are provided to maintain the flow of coolant, condensate and feed water.\r\n\r\nBoiling water reactor (BWR) -\u00a0\r\n\r\n Pressurised Water reactor (PWR)-\u00a0Pressurized Water Reactor (PWR) -Advantages and Disadvantages\r\n\r\nFast breeder reactor (FBR) -\u00a0Fast Breeder Reactor - Advantages and Disadvantages\r\n\r\n Advantages of nuclear power plant\r\n1. The fuel used in nuclear power plant is uranium; it does not release chemical or solid pollutants into the air during use.\r\n2. Space required is less when compared with other power plants.\r\n3. Fuel consumption is very less.\r\n4. Fuel transportation cost is low and no large storage area for fuel is required.\r\n5. The plant is not affected by weather conditions. The plant can function throughout the year (Hydel power plants depends on monsoon)\r\n6. By using nuclear fuel we can conserve the fossil fuels like coal, oil, gas etc for other purposes. For example coal can be used to power steam\r\nengines, oil can be used for running vehicles, and gas be used for cooking.\r\n7. Number of workers required is less.\r\n8. Nuclear power plant is the only source which can meet the increasing demand of electricity.\r\n9. A nuclear power plant uses much less fuel than a fossil fuel plant\r\n1 metric ton of uranium fuel = 3 million metric tons of coal = 12 million barrels of oil\r\n\r\n\u00a0Disadvantages of nuclear power plant\r\n1. Nuclear plants cost more to build than thermal or hydro electric power plants of the same capacity.\r\n2. Radioactive wastes must be disposed carefully, otherwise it will adversely affect the health of workers and the environment as a whole.\r\n3. Maintenance cost of the plant is high.\r\n4. Not suitable for varying load conditions\r\n5. Well trained persons are required to operate the plant.\r\n\r\nNuclear power stations in India\r\n\u2022 Tarapur Nuclear power station (Bombay) \u2013 Boiling water reactor \u2013 200 MW\r\n\u2022 Rana Pratap Sagar Nuclear power station (Kota in Rajasthan) \u2013 Two 200 MW\r\n\u2022 Kalpakkam Nuclear power station \u2013 Two 235 MW \u2013 Pressurised water reactor\r\n\u2022 Narora Nuclear power station (Uttar Pradesh) \u2013 Two 235 MW \u2013 CANDU reactor","headline":"Nuclear power plant &#8211; Diagram , Working , Advantages and Disadvantages","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-02-25","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/02\/nuclear-fussion-reaction-300x123.jpg","height":123,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/assembly-design-catia-v5-interview-question-and-answers/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/02/CATIA-V5-Assembly-design-300x164.jpg')"></div><span class="sr-only">link to Assembly Design &#8211; CATIA V5 | Interview question and Answers</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/assembly-design-catia-v5-interview-question-and-answers/">Assembly Design &#8211; CATIA V5 | Interview question and Answers</a></p></header><div class="excerpt"><p>Assembly Design - CATIA V5 | Interview question and Answers

Whereas component is a collection of features.\r\n\r\n3) What is visualization mode?\r\nIn this mode, only partial data is loaded to the memory of the hard disk. The data will be in the sellated form we cannot give constraints to the components in this mode.\r\n\r\n4) What is save extension of assembly file?\r\n. CAT Product\r\n\r\n5) What is design mode?\r\nIn this mode the data is fully loaded to the memory &amp; we can work on the components. The components in visualization mode can be brought into design mode by just double clicking on the components but vice versa is not possible by just double clicking.\r\n\r\n6) When we use propagate directory?\r\nIn save management, when we want to save the component files in the same file in which product is saved then we use PROPAGATE DIRECTORY. Then automatically the entire child files will be propagated to that particular directory.\r\n\r\n7) What is a scene? Where we use it give any one example?\r\nScenes enable capturing &amp; restoring the state of components in an assembly in a saved viewpoint.\r\n\r\n8) How many degrees of freedom will be there for any component in an assembly?\r\nSix degrees of freedom will be there for any constrained component in an assembly.\r\n\r\n9) In an assembly how do I measure degree of freedom of component?\r\nActivate the component &amp; then go for ANALYZE Degrees of freedom.\r\n\r\nCATIA V5 Assembly design\r\n\r\n10) What is use of stop manipulated on clash command?\r\nIt will stop the movement of component when clashed, in compass assisted movement.\r\n\r\n11) What is the function of \u2018overload properties\u2019 in contextual menu?\r\nIt gives away us the option not to copy a particular component into the drafting from assembly by just selecting it (the particular component) using the contextual menu with \u2018 overload properties\u2019.\r\n\r\n12) What is DESK command?\r\nThis command shows us how to view the relationship between different documents &amp; to obtain information about their properties. (Uncheck tools&gt;options\r\nWHITE-loaded.\r\nBLACK-not loaded in the current session.\r\nRED-not been found.\r\n\r\n13) Different types of CACHE?\r\n\r\nLOCAL CACHE: \u2013 A read or writes directory located locally on your machine &amp; used to store CGR files. The first time a component is inserted it is tessellated. This means that the corresponding CGR file is computed &amp; saved in the local cache as well as displayed in the\r\ndocument window. The next time this components is required, the CGR file which already exists (&amp; not the original document) ism automatically loaded from the local CACHE. The user is normally responsible for the local cache.\r\n\r\nRELEASED CACHE: - A read only cache that can be located any where on your network, several directories can be defined for RELEASED CACHE. If a CGR file cannot be found in the local CACHE, the software browses the released cache directories in their listed order to\r\nsee if the CGR file is located in any of them. If the CGR file is still not found, the component is tessellated &amp; the resulting CGR file is saved in the local CACHE. The site \u2018administrator\u2019 is normally responsible for the released CACHE. The default maximum CACHE size is 500MB. When the maximum size is exceeded, the automatic deletion of CGR files (on first in\/first out basis) is triggered.\r\n\r\n14) About EDIT \u2013LINKS?\r\nThis task shows how to display the document links. Only direct links i.e., External documents directly pointed to by the active document can be displayed using the\r\nEDIT-LINKS command. This activated inactive document must be activating before displaying their links. Note that you can also an element from the graph to display its links.\r\n\r\n15)What is CSG tree?\r\nCSG = Constructive Solid Geometry it is equivalent to specification tree in CATIA V5.\r\n\r\n16)What CGR stands for?\r\nCGR = Catia Graphic Representation.\r\n\r\n&nbsp;\r\n\r\n\r\nCATIA V5 Questions : Click here to See More Questions\u00a0\r\nBasic Of Catia v5 - Part 1 | Part Modelling Design - part 2 | \r\nSurface Design - Part 3 | Assembly Design -Part 4\u00a0\r\n\r\n\r\n\r\n\r\nMore Resources \/articles\r\nCAD Software | CAD Tutorials\r\nMachine Design Notes , article , Interview Que. and Ans.\r\nManufacturing Technology Notes , Articles\r\nDesign and Fabrication projects - Abstract , Report Download\r\nNew Mechanical Projects 2020 ( All Projects Post Index List )\r\n\r\n\r\n\r\n&nbsp;","headline":"Assembly Design &#8211; CATIA V5 | Interview question and Answers","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-02-25","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/02\/CATIA-V5-Assembly-design-300x164.jpg","height":164,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/surface-design-catia-v5-interview-question-and-answers/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/02/CATIA-V5-Surface-300x223.jpg')"></div><span class="sr-only">link to Surface Design &#8211; CATIA V5  | Interview question and Answers</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/surface-design-catia-v5-interview-question-and-answers/">Surface Design &#8211; CATIA V5  | Interview question and Answers</a></p></header><div class="excerpt"><p>Surface Design - CATIA V5 | Interview question and Answers
