...Rampal Coal-Fired Power Plant Who gains, who loses? Moshahida Sultana Ritu WHO does not know that Bangladesh needs more electricity for its economy to grow? Who does not know that every economic opportunity comes with an environmental cost, be it high or low, visible or less visible? But does this knowledge really leave us with no choice when Bangladesh signs three agreements with India to establish a 1320 megawatt coal- fired power plant in Rampal? No. Without answering the question “who pays the cost of environmental degradation and who are the ultimate beneficiaries from building the power plant?” we cannot justify building Rampal power plant. First, setting up Rampal power plant is not going to ensure our energy security; rather it may aggravate our existing problems. The newly formed joint venture company named Bangladesh India Friendship Power Company (BIFPC), with equal ownership of Bangladesh’s BPDB and India’s NTPC, will be a full-fledged commercial venture. A commercial venture with an objective of cost recovery and profit maximization is not a problem that may lead to project failure. Rather, the problem will be visible elsewhere. The source of finance and ownership will matter the most in this type of project’s sustainability. Initially Bangladesh and India will equally share up to 30 percent equity of this mega project. The remaining equity, which may be equivalent to $ 1.2 billion, will be taken as bank loan with help from the NTPC. Repaying the loan...

...Colton Caraway ID# 8940730499 Henry DRE 098 9/30/2015 Nuclear Power Plants As human beings we need to find a safe, reliable, long term solution to our energy needs. Researchers need to find and provide information to encourage the building of nuclear power plants. Researchers should present information that leads to building more nuclear power plants in order to provide a long term, a reliable, safer energy solution. The first reason why researchers should present information is to offer a long term energy solution. Nuclear power plants can last for years when taken care of properly. Indian point in upstate New York is a key example of a properly used power plant. According to Rudolph W. Giuliani, “ Nuclear power has proven to be an essential component of our region’s overall electric supply.” (Giuliani). With that it shows how it has been viewed very helpful first hand by the former mayor of New York City. A long term energy solution such as nuclear power will make it easier for people to have a more reliable energy source. The second reason why researchers should present information is to provide a reliable energy source. The nuclear power plants will produce a mass amount of reliable energy. Indian point has provided a reliable source of energy for the state of New York through two hurricanes and has not stopped. Security is a big factor in making our nuclear power plants reliable. According to James Mahaffey, “Anticipating problems, the Generation III reactor have...

...signed between Bangladesh Power Development Board (BPDB) and India's state-owned company National Thermal Power Corporation (NTPC). The project situated in Rampal, Bangladesh was designated to be completed by 2016. Bangladesh and India shared the implementation cost on a 50:50 equity basis. The remainder cost of 1.5 billion US dollars will be taken as loans from the banks by the Indian based company. Therefore, India is the majority share holder of the power station and India is entitles to receive a major benefit of power supply. Though, the plant has been situated in Bangladesh, India is said to be a part owner of the power station. The proposed project, on an area of over 1834 acres of land, is situated 14 kilometres north of the world's largest mangrove forest Sundarbans which is a UNESCO world heritage site. A coal based power plant creates an alarming environmental pollution. The emission of toxic sulphur gases and nitrogen gases reduces the air quality in surrounding areas. It destroys the vegetation up to 50 kms from the place of the plant. Thus emission of hazardous gases will increase the local temperature. The result of the operation of the coal plant will give to a huge deposit of ash consisting of residue from heavy metals. Surely, the toxic heavy metals contained in this dumped ash will mixed with rain water and leached in to the ground and contaminated both ground and surface water the impact of which will not be limited to the plant site, rather, spreads through...

...NUCLEAR POWER PLANT IN KUDANKULAM What is Nuclear Power? Nuclear power, or Nuclear energy, is the use of exothermic nuclear processes, to generate useful heat & electricity. The term includes the following heat producing processes – nuclear fission, nuclear decay and nuclear fusion. Uses 1. Nuclear power is a low carbon method of producing electricity & in 2011 nuclear power provided 10% of the world's electricity. 2. Many military and some civilian (such as some icebreaker) ships use nuclear marine propulsion, a form of nuclear propulsion. 3. A few space vehicles have been launched using full-fledged nuclear reactors: the Soviet RORSAT series and the American SNAP -10 A. 4. Both Fission and fusion appear promising for space propulsion applications, generating higher mission velocities with less reaction mass. (Due to the much higher energy density of nuclear reactions: some 7 orders of magnitude (10,000,000 times) more energetic than the chemical reactions which power the current generation of rockets). 5. International research is continuing into the use of nuclear fusion, and additional uses of process heat such as hydrogen production (in support of a hydrogen economy), desalinizing sea water, and for use in district heating systems. What is Nuclear Reactor? A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for generating...

..."Complete analyses of inherited influences to natural populations could make the information available and desirable to forecast retrieval times for wild groups at Fukushima as well as any sites of upcoming nuclear coincidences," Mousseau said. "There is a vital need for larger investments in simple scientific research of the wild creatures and plants of Fukushima." (Genetic Association, 2014) The damage of the Fukushima Daiichi nuclear power plant in March 2011, instigated by volcanic activity and succeeding a tsunami, gives rise to massive radioactive contamination of the Japanese continental. In November 2011, the Japanese Science Ministry said that the long-lived radioactive cesium had contaminated 11,580 square miles (30,000 sq km) of the terrestrial surface of Japan. (AJW by The Asahi Shimbun, 2011) Some 4,500 square miles (an area nearly the size of Connecticut) and was found to have radiation echelons that surpassed Japan’s allowable exposure rate of 1 mSV (millisievert) per...

...Thermal Steam-turbine Power Plants Large steam-turbine plants have two forms: condensing plants, electric power plants. The great masses of hot steam, having accomplished the mechanics work in the turbines of condensing steam-turbine plants, are condensed - i.e. are cooled down and turned back into distilled water, and returned to the boiler for production of steam to activate the turbine. Condensation of steam takes place in condensers where the hot steam is cooled when it comes in contact with tubes through which cooling water, supplied from a water reservoir (river or lake), is circulated. This cooling water, after it takes the heat from the spent steam, is returned to the water source carrying along with it the unutilized heat energy. This water is called the circulating water. The importance of the distilled water for feeding steam boilers is extremely great since chemical clean water decreases the formation of scale in the boiler tubes, and thus, makes their service life longer. Condensing plants of large generating capacity are built close in sources of fuel, in order not to transport large quantities of fuel over considerable distances. The electric power generated in such plants is transmitted over long distances for the supply of large industrial regions. So these plants are called regional thermal power plants. Heat and electric power plants, in addition to electric power generation, also supply heat to closely located...

...In a world where energy is desperately needed, nuclear power plants have risen up as a possible solution. However, there have been controversial discussions as to whether or not harnessing this energy is worth the incredibly high risk. This is further magnified by two devastations that have occurred in the past, both of which were the result of malfunctioning nuclear reactors. One was the Fukushima incident in Japan, a series of explosions in the aftershock of a natural disaster. The second was at the Chernobyl Nuclear Power Plant, which released tons of radioactive materials and destroyed many lives. The power plant in Chernobyl, Ukraine, was the pride of the Soviet Union. One midnight test, on April 26, 1986, went terribly wrong under the control of junior scientists. Due to miscommunication, only six control rods were present in the core as the water supply was cut off, and the reactor became overheated. Soon enough, it exploded; the roof was blown off and a large fire ensued. In all, eight thousand people died from the explosion, both directly and indirectly. The rate of thyroid cancer in nearby areas increased by one hundred times. It didn't just affect Ukraine, either—ten days later, a toxic cloud from the reactor reached Japan and America. A...

...Nuclear Reactor Power Plant Control Systems Mechatronics Professor 13 October 2013 Table of Contents Heading Page # Introduction History Safety Control Systems Coolants Pressurizer Moderator Control Rods Regulations Disposal Conclusion Works Cited Introduction Control systems are an integral part of the nuclear reactor and without the implementation of an effective control system along with constant monitoring and maintenance catastrophic accidents will occur. This report will introduce the important control systems found in many of the most common nuclear reactors along with an explanation on how they work and how they're implemented. First we must go back into the histories to gain a better understanding of why these control systems are so important and consequences that resulted when control systems are not implements or not used properly. History To know the history of nuclear power plants, one must first understand what a nuclear power plant is. A nuclear power plant is very similar to that of any other steam-electric power plant, in that water is heated and the steam from the water turns turbines, thus creating electricity. The major difference is how the power plant generates heat. The source of the heat from nuclear power plants comes from nuclear fission, rather than from coal, oil or gas. In 1934, a physicist by the name of Enrico Fermi conducted the first experiments that resulted...

...Power Shortage in Mindanao: A Call for New Power Plants It is swirling in the news that Mindanao suffers from power shortage. According to the news aired on March 27, 2012 over GMA News' Saksi, The Energy Department had said that projected peak demand in Mindanao is 1,300 MW although the available capacity is only at 1,100 MW, excluding the required reserve margin to maintain the "integrity" of the Mindanao Grid which is pegged at 250 MW. The same television report said the power shortage was reportedly caused by the lack of electricity being produced by the hydro electrical power plants in Mindanao due to heat brought by the dry season. "Considering the future lower rainfall forecast in Mindanao, we cannot rely solely on hydropower plants. Non-hydro base-load is immediately needed and this will only happen if everyone cooperates,” Energy Secretary Jose Rene Almendras said. According to the DOE's Mindanao Field Office curtailment schedule obtained by GMA News Online on March 28, 2012, some parts of Region IX, X, XI, XII, and XIII have recently been experiencing rotational brownouts. Among these areas are: Pagadian City, Zamboanga del Sur (4 hrs/day), Zamboanga City (4 hrs/day), Maramag, Bukidnon (1 hr/day), Iligan City, Lanao del Norte (2.5 hrs/day), Marawi City, Lanao del Sur (3.5 hrs/day), Tubod, Lanao del Norte (3 hrs/day), Ozamis City, Misamis Occidental (3 hrs/day), Calamba, Misamis Occidental (5 hrs/day), Digos City, Davao del Sur (3 hrs/day), Tagum City, Davao Norte...

...Electricity Generation by Hybrid Biomass Power Plant From Waste For Bangladesh Md. Rakibul Islam Monshy Department of Electric Engineering & Computer Science North South University, Dhaka Abstract- Hybrid renewable Biomass Power is becoming popular for remote area power generation applications due to advances in renewable energy technologies and subsequent rise in prices of petroleum products. A hybrid energy system usually consists of two or more renewable energy sources used together to provide increased system efficiency as well as greater balance in energy supply. Hybrid renewable energy systems is one of the most promising applications of renewable energy technologies in remote areas, where the cost of grid extension is prohibitive and the price of fossil fuels increase drastically with the remoteness of the location. It has been demonstrated that hybrid energy systems can significantly reduce the total life-cycle cost of stand-alone power supplies in many situations, while at the same time providing a more reliable supply of electricity through the combination of energy sources. Applications of hybrid systems range from small power supplies for remote households providing electricity for lighting or water pumping and water supply to village electrification for remote communities. Mixed combinations of renewable energy systems are also possible, that is applications where different renewable energy technologies are applied in one location without the systems being...

The thermal performance data obtained from MAHAGENCO KORADI UNIT 5 thermal power plant shows that heat rate and boiler efficiency is changing constantly and the plant is probably losing some Megawatts of electric power, and more fuel usage thus resulting in much higher carbon footprints. It is very difficult to analyse the raw data recorded weekly during the full power operation of the plant because a thermal power plant is a very complex system with thousands of parameters. Thus there is a need for nonlinear modeling for the power plant performance analysis in order to meet the growing demands of economic and operational requirements. The intention of this paper is to give an overview of using artificial neural network (ANN) techniques in power systems. Here Back Propagation Neural Network (BPNN) and Radial Basis Neural Network (RBNN) are used for comparative purposes to model the thermodynamic process of a coal-fired power plant, based on actual plant data and this works as the internal model for prediction...
