The example of components are pump compressor, turbine, reactor, and heat exchanger. By considering the constitutive equation for the given type of fluid, thermodynamic state of each point can be analyzed. As a result, the thermal efficiency of the cycle can be defined. Examples of the cycle include the Carnot cycle, Brayton cycle, and Rankine ...
There are a wide variety of fields associated with nuclear engineering, but computers and associated software are used most often in design and analysis. Neutron kinetics, thermal-hydraulics, and structural mechanics are all important in this effort. Each software needs to be tested and verified before use. [1]
Following the Chernobyl disaster, DOE undertook a re-assessment of the safety of all its test and production reactors throughout the United States. The RELAP5 code was chosen as the thermal-hydraulic analysis tool because of its widespread acceptance. The application of RELAP5 to various reactor designs created the need for new modeling ...
Nuclear engineers work in such areas as the following: [9] [10] [11] Nuclear reactor design, which has evolved from the Generation I, proof-of concept, reactors of the 1950s and 1960s, [12] to Generation II, Generation III, and Generation IV concepts; Thermal hydraulics and heat transfer.
Certain aspects of the original RBMK reactor design had several shortcomings, [3] such as the large positive void coefficient, the 'positive scram effect' of the control rods [4] and instability at low power levels—which contributed to the 1986 Chernobyl disaster, in which an RBMK experienced an uncontrolled nuclear chain reaction, leading to ...
Reactors that use lead or lead-bismuth eutectic can be designed in a large range of power ratings. The Soviet union was able to operate the Alfa-class submarines with a lead-bismuth cooled intermediate-spectrum reactor moderated with beryllium from the 1960s to 1998, which had approximately 30 MW of mechanical output for 155 MW thermal power (see below).
International Reactor Innovative and Secure (IRIS) is a Generation IV reactor design made by an international team of companies, laboratories, and universities and coordinated by Westinghouse. IRIS is hoped to open up new markets for nuclear power and make a bridge from Generation III reactor to Generation IV reactor technology. The design is ...
Entrance to the Radiation Center. The Oregon State University Radiation Center (OSURC) is a research facility that houses a nuclear reactor, Gammacell 200 irradiator, several radiation laboratories, and multiple high-bay thermal hydraulics laboratories at Oregon State University (OSU) in Corvallis, Oregon, United States.
