Engineering 0011 R09 THE NEED FOR THE INTERNATIONAL THERMONUCLEAR EXPERIMENTAL REACTOR PROJECT AND THE DEMONSTARTION POWER PLANT PROJECT FOR NUCLEAR ENERGY Grzegorz Piszczek (grp12@pitt.edu) THE FUTURE OF ENERGY THE ITER PROJECT AND THE DEMO PROJECT In order to meet the growing demands for energy, a safe, renewable, and reliable resource must be used. As one of the fourteen NAE Grand Engineering Challenges, fusion energy, being the energy source of the universe, is becoming more of a reality as being the energy that runs our lives, and should be further supported [1]. Even prominent CEOs in America are saying that finding a new energy source is one of the largest problems we face today [2]. Fusion energy can be considered one of the best forms of energy because of the ethical ideals it upholds. According to the code of ethics given by the National Society of Professional Engineers (NSPE), engineers must “strive to serve the public interest,” while at the same time “hold paramount the safety, health, and welfare of the public” [3]. Through its lack of harmful emissions, abundance of fuels, and deterrence to attacks from leakage and explosions, fusion energy may be the most ethical and most beneficial form of renewable energy. Fortunately, an engineering project being conducted in southern France is currently attempting to take the first steps in creating a process to make a commercial form of fusion energy [4]. The International Thermonuclear Experimental Reactor (ITER) is undergoing construction, and, when finished, will start testing new technologies that will make commercial fusion energy possible [4]. This kind of technology, and even any kind of advances in technology, is very important for the future, and is especially important for aspiring engineers. It is very beneficial for an engineering student to research a topic of interest in engineering to further expand his or her understanding as well as create a foundation to build upon for a career. The ITER project was created by a group of nations who agreed that a new, clean, and renewable energy resource must be researched to benefit mankind [4]. Currently, the U.S.A, The People’s Republic of China, Japan, the former Soviet Union, the Republic of Korea, and India, plus the European Union, are taking part in the project [4]. It was agreed upon that, in addition to financial contributions, each nation would give and share staff, materials, and research with the idea that each nation would have the tools to reconstruct its own fusion plant [4]. Located in Cadarache, France, the site will be home to the ITER headquarters, the Tokamak, research laboratories, and auxiliary buildings, totaling thirty-nine buildings [4]. At the core will be the Tokamak, where fusion experiments will take place. The Tokamak is a doughnut shaped chamber surrounded by superconducting magnets, Lithium-covered walls, and a solenoid in the middle. Plasma, the fuel of the experiment, will fill the hollow ring inside the chamber. The actual fusion reaction will release enormous amounts of energy in the form of heat [4]. A follow up program, called the Demonstration Power Plant (DEMO), will use the released heat as the energy source for an electrical power plant [4]. The DEMO project will be an add-on to the Tokamak chamber, and will extract heat to create steam, and, through a system of turbines, create commercial electricity. ETHICS OF FUSION ENERGY As part of the code of ethics of the American Institute of Chemical Engineers, engineers uphold the integrity, honor, and dignity of their profession by “using their knowledge and skill for the enhancement of human welfare” [6]. The use of fusion energy enhances humanity more than current forms of gaining energy, i.e. burning fossil fuels, fission energy. Contrary to fission reactions and burning oil, fusion reactions create virtually no harmful wastes. The most efficient fuels used for a fusion reaction are Deuterium and Tritium, both of which are isotopes of Hydrogen. Deuterium can be easily found and extracted from water, which there is abundance of. Tritium is slightly radioactive and much rarer. However, the ITER project solves that problem by “breeding” Tritium inside the fusion reactor [4]. The products of a fusion reaction involving Deuterium and Tritium are Helium, a neutron, and energy. Lithium covered walls react with the neutron, creating more Tritium which can be extracted and reused [4]. No gaseous CO2, SO2, or WHAT IS FUSION? Fusion is the process where the nuclei of two or more atoms combine to form a single heavier nucleus and release a large quantity of energy [5]. This is the same process that the sun uses to release light and heat. In order to start such a process, an incredible amount of energy is required. Extreme gravity creates the conditions needed for a fusion reaction to occur in stars. At a temperature of over 100,000,000 degrees Celsius, the atoms are in such an agitated state that they overcome the electrostatic repulsion of like charges [5]. It is incredibly difficult to reach the right conditions on Earth. However, the ITER will have the capacity to do so. Moreover, the ITER will go beyond reaching the minimum conditions and will create more output energy than input, energy that will be used commercially in the future [4]. University of Pittsburgh Swanson School of Engineering November 1, 2011 1 Grzegorz Piszczek NOX are released, and no dangerous radioactive substances are released [4], [5]. In addition, no burning of fossil fuels will be used in the DEMO plant, since its sole source of energy is the released heat [4]. Even the site itself will be made to the highest environmental standard, making the least impact against its natural surroundings. The risk of adding excess CO2 is completely done away with, as well as finding processes to get rid of radioactive material. Ethically, fusion energy is virtually the ideal energy source. In addition to environmental impact, fusion energy also has a very high standard of safety. Although a fusion reaction involves manipulating nuclei, controlling neutron projection, and capturing extremely high amounts of energy, a controlled fusion experiment is actually quite safe. Unlike a fission reaction, a very small amount of fuel is needed to start the reaction, about 0.5 grams of Deuterium/Tritium mixture [4]. Also, even though incredibly high temperatures are necessary for the reaction, the entire experiment is finetuned enough that the reaction can be brought to a halt in seconds [4]. The heated plasma cools down in seconds when it comes into contact with the walls of the chamber. Despite the extreme conditions, the ITER is a very safe and easily controlled reactor that poses little to no harm to its surroundings [4]. Moreover, a fusion reaction plant has very little potential in being part of a terrorist attack. The ease in shutting down and disabling the reactor is so great that any kind of attack would be rendered useless. In fact, supporting the ITER and DEMO projects and others like it may eliminate the fear of any kind of nuclear leaks or explosions. Ethic codes such as reporting to employer under circumstances that endanger life and performing services only in areas of competence are extremely important to uphold in the field of nuclear energy [3]. Any mistakes made can potentially endanger the lives of the workers as well as the surrounding environment. Only highly trained scientists should be able to work on the ITER project. Although during the actual reaction the risk of explosions and leaks are fairly minimal, the processes before the reaction must be conducted perfectly, and it is imperative that good judgment and high skill are implemented. These ethic codes serve as a guideline for engineers to work efficiently with the responsibility of keeping human lives safe. ITER and DEMO projects strive to uphold the ethical ideals listed in the NPSE Code of Ethics [4]. Part of the mission in the American Society for Engineering Education is to provide an education on the value of engineering to the public [7]. Writing a research paper helps this cause by educating students, who can give back in the future through their work. By both keeping a professional outlook on their work, as well as promoting the welfare of the public, the ITER team has inspired me to continue striving for an education in engineering. IMPACT OF FUSION ENERGY Resources such as natural gas and oil will inevitably run out. Fusion energy is being made possible by the intricate engineering behind the ITER project. Because the demand for energy is increasing, a reliable source such as fusion energy will be necessary. Unfortunately, it has been difficult to find funding and support, especially here in the U.S. Government funding and involvement has been decreasing, and companies hoping to have nuclear facilities built are waiting longer and longer before the government gives them what they need [8]. Cost effectiveness, reliability, environmental impact, and safety have the highest standards when it comes to the ITER and DEMO projects. By an ethical standpoint, fusion energy both promotes and protects the welfare of the public. It is important that research is supported for nuclear energy now, since it will be the leader in energy in the near future. It is important that engineering students everywhere take the time to research a topic of interest in order to better understand the work and the ethics behind their field of engineering.
