Special theory of relativity German-born physicist Albert Einstein introduces his special theory of relativity, which states that the laws of nature are the same for all observers and that the speed of light is not dependent on the motion of its source. Einstein wins the Nobel Prize in physics in for his work on the photoelectric effect. Neutron is discovered English physicist and Nobel laureate James Chadwick exposes the metal beryllium to alpha particles and discovers the neutron, an uncharged particle. It is one of the three chief subatomic particles, along with the positively charged proton and the negatively charged electron.
See Article History Nuclear engineering, the field Nuclear engineering engineering that deals with the science and application of nuclear and radiation processes. These processes include the release, control, and utilization of nuclear energy and the production and use of radiation and radioactive materials for applications in research, industry, medicine, and national security.
Nuclear engineering is based on fundamental principles of physics and mathematics that describe nuclear interactions and the transport of neutrons and gamma rays. These phenomena in turn are dependent on heat transfer, fluid flow, chemical reactions, and behaviour of materials when subjected to radiation.
Nuclear engineering is therefore inherently a multifaceted disciplinerelying Nuclear engineering several branches of physics, and, like the aerospace industryit relies to a large extent on modeling and simulation for the design and analysis of complex systems that are too large and expensive to be tested.
History Nuclear engineering was born in the 20th century with the announcement in of the discovery of nuclear fission by the German chemists Otto Hahn and Fritz Strassmann. It was almost immediately realized that a weapon of enormous explosive energy might be possible by employing fission, and during World War II the race to be the first to build this weapon led to the creation of the Manhattan Project in the United States.
The seminal work of the Manhattan Project, led by Italian physicist Enrico Fermiwas the building of the first nuclear reactor in at the University of Chicago. Named Chicago Pile No. The Hanford production reactors were complex systems that required the talents and efforts of a large number of traditional engineers from all disciplinesbut the engineers were supplemented by physicists and mathematicians who understood the complex nuclear phenomena involved and could work with the engineers to design and analyze early reactor systems.

Navy after the war was a key driver for the then unnamed discipline of nuclear engineering. The design and analysis of nuclear reactors, whether on land or in a submarine, requires an understanding of the complex nuclear phenomena going on within the reactors as well as a practical knowledge of how to go about designing and putting together the fuel assemblies, cooling systems, pressure vessels, control systems, and countless other systems needed for the reactor plant.
A growing understanding of nuclear physics within the reactor and of radiation transport within and outside the reactor led to the birth of a new engineering discipline, nuclear engineering, that supplemented the traditional and necessary engineering disciplines needed to design, analyze, build, and operate a nuclear reactor plant.
In the late s and early s, as the many potential peaceful uses of nuclear energy became evident, schools of reactor technology were established by Oak Ridge National Laboratory in Tennessee and by Argonne National Laboratory near Chicago.
Today there are more than 40 departments and programs offering courses in nuclear engineering and related fields in the United States and Canada, and more than 60 such programs have been established elsewhere in the world.
While the primary driver for the growth of nuclear engineering has been nuclear power, the discipline is much broader than that one application.
Nuclear engineering also includes fields such as radiation measurement and imaging, nuclear fusion and plasma physicsnuclear materials, and medical and health physics. All of these functions apply to nuclear power and, to lesser degrees, to other branches of nuclear engineering, depending on the maturity of the field.
Nuclear engineers perform these functions for various categories of employers: Architectural engineering firms, for which they handle design, safety analysis, project coordination, construction supervision, quality assurancequality control, and related matters.
Reactor vendors and other manufacturing organizations, for which they pursue research, development, design, manufacture, and installation of various components of nuclear systems. Electric utility companies, for which they handle planning, construction supervision, reactor-safety analysis, in-core nuclear fuel management, power-reactor economic analysis, environmental-impact assessmentpersonnel training, plant management, operation-shift supervision, radiation protection, spent-fuel storage, and radioactive-waste management.
Hospital and medical centres, where they conduct applied research and also develop and carry out diagnostic and therapeutic radiation procedures on patients. Regulatory agencies, for which they undertake licensing, rule making, safety research, risk analysis, on-site inspection, and research administration.
Defense programs, for which they are employed in naval propulsion and nuclear weapons programs. Universities, where they teach prospective nuclear engineers and perform basic and applied nuclear engineering research. National laboratories and industrial research laboratories, where they carry out basic and applied research and development on a variety of nuclear-related topics.
Branches of nuclear engineering Nuclear power The greatest growth in the nuclear industry has been in the development of nuclear power plants.
Today more than nuclear reactors generate electricity around the world. Almost one-quarter of them can be found in one country—the United States —and most of the rest are located in a relatively small number of countries—most notably France, Japan, Russia, South KoreaIndia, Canada, the United Kingdom, and China.
Clearly, nuclear power is an important branch of nuclear engineering. It includes a number of specialties, some of which are described in this section.
Reactor physics and radiation transport Nuclear engineers analyze the complex physical and radiation transport phenomena occurring within and external to a nuclear reactor. Working closely with engineers and scientists from other fields, they model complex phenomena such as heat transfer, fluid flow, chemical reactions, and materials response.
Modeling and simulation play a dominant role in this area. Reactor thermal hydraulics and heat transfer The energy released by fission is carried by the reactor coolant out of the reactor core and is used to create steam to turn a turbine and generate electricity.Nuclear Engineering,Ltd.
