Schaub 6:00 L12 THE ETHICS BEHIND BUILDING A NUCLEAR REACTOR John D’Alessio (jwd27@pitt.edu) INTRODUCTION: ARISING ETHICAL ISSUES FOR NUCLEAR POWER With great power comes great responsibility. This saying is applied to nuclear energy because of its surplus power, but volatile nature. Radioactive material is difficult to store, can present a threat to public health, and is associated with the most powerful manmade weapons. As an engineer posed with the problem of building nuclear reactors, many controversial issues must be addressed. It is the price for a source of energy that is less harmful to the environment and more sustainable than coal and oil. I am asked to produce a fast breeder nuclear reactor near a busy city in a politically unstable country. The ethical issues that arise with this situation include the ramifications of the location of the plant: how it affects the public’s well-being and how the locals react to the idea. Global safety will also need to be addressed because although the plant is designed to produce energy, it produces byproducts used to create nuclear weapons. How Nuclear Reactors Work Nuclear reactors produce energy by causing an atomic chain reaction that spins turbines and produces electricity. A lone neutron is fired at a fuel rod of Uranium-235 causing it to split into new elements and loose neutrons. These loose neutrons then travel to the next fuel rod and cause another reaction [1]. The reaction produces heat, which transforms water into steam [1]. The steam then travels down a tube and rotates the turbines [1]. More complex reactors are also able to create fuel while producing energy. These are known as breeder reactors, breeder referring to the ability to generate new fuel [1]. Fast Breeder Reactors Fast breeder reactors, a special form of breeder reactors, work very similarly to the more common light water reactors, but with one key difference. Liquid sodium is used as the primary heat conveyer rather than pressurized water [2]. In a light water reactor, water fills the tank where the fuel rods are held and the reaction occurs [1]. The water absorbs the heat and reaches a temperature of around 300 °F [2]. The neutrons travel through water slowly, making it difficult and unlikely for breeding to occur [1]. Liquid sodium can reach upwards of 800 °F and allows neutrons to travel much quicker, hence University of Pittsburgh, Swanson School of Engineering 1 2013-10-29 the name “fast” reactors [2]. In all reactors there are control rods that absorb excess neutrons to keep the reaction from becoming too violent. However, in breeder reactors there are also rods of “fertile material” usually in the form of Uranium238, a non-fissionable atom. When this is bombarded with neutrons, Plutonium-239 can be created and this is fissionable [1]. Unfortunately, safety is a main concern for fast breeder and other reactors. ETHICS INVOLVED WITH THE SAEFTY OF REACTORS The safety of the nuclear reactor’s design is addressed first. According to the National Society of Professional Engineers code of ethics, engineers “hold paramount the safety, health, and welfare of the public” [3]. The reactor I am building will use liquid sodium rather than the safe version of water. Liquid sodium may be more efficient, but it is also unpredictable. When exposed to air, liquid sodium is known to combust and burn [1]. Any contact with water will cause an immediate explosion [1]. It is also very corrosive, causing a problem with the piping [1]. Any miscalculations could become catastrophic. These incidents can compromise the structure of the reactor and cause a meltdown. This is similar to the accident that occurred in Fukushima, Japan when a tsunami damaged and caused the meltdown of a nuclear reactor. This resulted in the relocation of nearly 130,000 people and 1,600 deaths [4]. However, the country we are creating this reactor for needs the energy. Why the Fast Breeder Reactor is Important There are risks involved, but fast breeder technology is one of the most efficient ways to produce energy. Fast breeder reactors will be able to convert current nuclear waste into usable material by a process known as reprocessing [1]. Reducing the waste is not only good for public safety, but it will also reduce the amount of uranium mined, as more power will be generated per unit used [1]. It is said that, “the most important advantage is they multiply the existing fuel supply by a factor of at least 50 to 75 times” [5]. This is important because with current technology, the earth will run out of useable uranium within the next 90 years [5]. Nuclear power is also one of safest energy sources. John D’Alessio related disasters. Only 0.1 percent of the 110,000 Chernobyl cleanup workers have developed leukemia [6]. In addition, zero of the deaths connected to Fukushima were related to radiation; they were all caused by poor relocation efforts [4]. Radiation and meltdowns are not the only harmful things that can come from nuclear reactors. Nuclear Reactor Safety Compared to Other Forms of Energy The Chernobyl incident is projected to cause the death of nearly 9,000 people due to cancerous effects [4]. In 1975, 30 dams associated with the production of hydroelectric power burst in China, causing flooding and killing over 230,000 residents [4]. New Scientist Magazine did a study on the death tolls from different sources of power. The results go against common assumptions. Coal causes 2.8 deaths per 10 billion kilowatt hours produced, while hydroelectric energy is accountable for 1.0 and natural gas 0.3. Nuclear power has only been the cause of 0.2 deaths per kilowatt hour produced [4]. This shows that nuclear power is by far the safest and does not release harmful emissions into the atmosphere [4]. Creating this reactor is the right choice because I have trust in myself and my colleagues. I am confident that it will be created with standards that reduce the risk of failure to zero. However, I am not the only one that needs to be convinced it is safe. Plutonium Byproducts A key component of fast breeders is the use of and production of Plutonium-239, also known as weapons-grade plutonium. Plutonium is one of the most toxic substances on Earth: “the release of one ton of plutonium into the atmosphere could give every person on earth lung cancer, and operating breeder reactors on a large scale would double the amount of plutonium on earth every ten years” [8]. Increasing the amount of plutonium also increases the materials for nuclear weapons. This is a key concern whether or not politically unstable countries should be able to possess a reactor. Today’s working reactors still produce radioactive material. If it is removed at a correct time, it can produce a nuclear weapon [8]. This requires very large machinery and a long process of exacting that is not able to be concealed due to international over watch protocols [8]. Fast breeder reactors provide a much more convenient window and easier process to extract materials [8]. Reprocessing old fuel rods requires transportation in-between different sites to prepare the rod to be reused [1]. The U.S. has banned this process because it would cause the travel of tons plutonium across the country via heavily guarded trains [1]. My colleagues and I have been asked to make the decision on whether or not the reactor should be designed to involve reprocessing. However, we are not qualified to make this decision. PUBLIC OPINION ETHICS AND GLOBAL CONSEQUENCES Public opinion is an issue when creating large manmade structures in a populated area. The “not in my back yard” syndrome explains how a person may accept the idea and safety of a nuclear power plant, but not if it can directly affect him [5]. Attitude towards nuclear power is negative because of the consequences that are associated with them. On April 26, 1986 a nuclear reactor meltdown in Chernobyl, Ukraine caused an explosion which produced 200 times more radiation than what had been dropped onto Japan during World War II [6]. This affected over 7 million people and 63,000 square miles of land [6]. Incidents such as this and the meltdown in Japan cause people to resist the construction and evolution of reactors. My colleagues and I will need to educate the public about the safety of nuclear reactors. COMPLICATIONS OF COMPLETING THE PROJECT Engineers should only preform duties that are in their area of qualifications [7]. We do not have sufficient knowledge of the country’s political situation and whether or not the government can regulate such a high security process. My qualifications as an engineer allow me to make decisions that are based around the design and construction of the plant that I am asked to build. An example of working outside qualifications can be shown by a prior president of the United States. In 1964, President Lyndon B. Johnson took the reins on the U.S. involvement in Vietnam and turned it from a small intervention to all out military conflict [9]. Johnson was qualified as a political leader, but had no military background [9]. However, he still required his personal consent prior to any major acts being carried out [9]. His decisions were based Information Presented The American Nuclear Society code of ethics states that information is presented “with their bases, truthfully, and are honest and truthful in all aspects of our professional activities” [7] Public statements and presentations on the subject must also be truthful [7]. To adhere, I will address the fact that catastrophic incidents have occurred involving nuclear reactors, most notably Chernobyl, Fukushima and Three Mile Island. On other side, nuclear power has the lowest death to kilowatt hours produced ratio, and the worst nuclear incident is not even comparable to other energy 2 John D’Alessio on opinion polls and took an excessive time to relay back to the front lines [9]. 60,000 American lives were lost and although Johnson’s unqualified decisions were not all to blame, they had an impact [9]. Due to my code of ethics I will refuse to make a decision on whether or not to use reprocessing. If I was to make an uneducated decision, the aftermath could be tragic and endanger the public. Unfortunately, one of my colleagues views the situation differently and wants to act as the decision maker. report my coworkers for their unethical decisions because “engineers having knowledge of any alleged violation of this Code shall report thereon to appropriate professional bodies and, when relevant, also to public authorities” [3]. They went against engineering ethics by giving bribes, signing for areas of qualifications they did not have, and for possibly endangering the public. CONCLUSION: RESOLVING MORAL PROBLEMS Peer Pressure Our project is now placed on hold until the unethical issues are resolved in our team. The poor country will now go without the energy for many years to come. My actions cost the country clean sustainable energy and I accept that responsibility because of my ethics. Engineers are faced with tasks that can have pros and cons. They need to weigh those odds to see if the pros outweigh the cons. However, there are some aspects that corrupt a project and cannot be bargained with. These are held in various codes of ethics and while working on my project I was faced with many. Public safety comes first and this become complicated when working with nuclear power. There are many aspects of a fast breeder reactor that can be dangerous such as the liquid sodium coolant and plutonium byproducts. The public must be accurately informed about these dangers by the engineer. The engineer must also only work in fields of his competence, resist bribes and peer pressure, and report all incidents of other engineers breaking the code. Engineers solve problems and follow ethics to prevent more harms from occurring. The reactor plan must be signed by all the operational engineers in order for building to begin. Of my colleagues, I am the only one who will not sign for the reprocessing aspect of the plant. I cite them a line from the NSPE code of ethics: “engineers shall not affix their signatures to any plans or documents dealing with subject matter in which they lack competence” [3]. They insist that I sign it, and as the overbearing peer pressure begins to kick in, I think of Pixar’s film Finding Nemo. This is a story of a persistent father that will stop at nothing to find his lost son, but many do not pay attention to why Nemo got lost in the first place. He is pressured by his friends, colleagues, to do something dangerous and rash [10]. They convince Nemo to approach a boat [10]. As a consequence, he is abducted [10]. Without the peer pressure, Nemo’s ethics would have kept him away from the boat and the whole situation could have been avoided. I learn from Nemo’s mistake and refuse to give in. My ethics are upheld, but my colleagues’ assault does not stop. Compensation and Following Ethics REFERENCES These men that I work with are my friends, they have met my family and know my secrets. My poor financial standings is well known and is being taken advantage of. By signing the papers I would be offered a vice president position and receive a large salary raise. Two of my kids are going through college and I need the money, but my morals do not let me take it. As an engineer, I may not “attempt to gain employment or advancement by… improper or questionable methods” [3]. I think back to what happened in the Disney movie Remember the Titans. In this story about a racially divided football team, the assistant coach Bill Yoast is faced with a similar decision [11]. He is addressed by the school board and told that if he intentionally loses the next game, he will be inducted into the Hall of Fame [11]. This opportunity is presented to him because the board wants the current African American head coach to be fired [11]. Yoast insures that a clean game is played and loses his chances at the Hall of Fame [11]. He knows he did the right thing as the Titans go on to win the State Championship.
