Creator:: Robinson, Matthew Loren
Abstract:: An enabling technology for long duration, deep space missions is the availability of a high power, long-lived power supply. The goal of this work is the design of a self-regulating deep space nuclear reactor. The design objectives are to produce 250 kWth for a 25-year period using the presence of...
Resource Type:: Dissertation

Creator:: Wuth, Bradyn J.
Abstract:: Some of the next generation of small modular reactors have been designed with helically coiled steam generators integrated into the reactor vessel to enhance natural circulation. According to the developers of TASS/SMR, a one-dimensional thermal hydraulic code written to model the Korean Atomic Energy Research Institute's SMART reactor, the Žukauskas...
Resource Type:: Masters Thesis

Creator:: Prichard, Andrew W.
Abstract:: The United States nuclear industry is under significant public pressure to close the nuclear fuel cycle. Closing the fuel cycle will require that nuclear waste, fission products and transuranics, except plutonium (actinides), be disposed of by permanent burial. The actinides can be buried with the fission products, but this will...

Creator:: Kliewer, Charles P.
Abstract:: A significant amount of interest has been aroused recently concerning the advancement of the current pressurized water reactor core designs with a special emphasis towards improving the conversion characteristics of these reactors. Most reports have been divided into two camps; those that deal with the neutronic aspects and those that...
Resource Type:: Masters Thesis

Creator:: Gedeon, Stephen R.
Abstract:: Preliminary nuclear design studies have been completed on ten configurations of nuclear reactors for low power (1-30 kWe) space applications utilizing thermionic energy conversion. Additional design studies have been conducted on the TRICE multimegawatt in-core thermionic reactor configuration. In each of the cases, a reactor configuration has been determined which...

Creator:: Lee, Hsing Hui
Abstract:: Incore thermionic space reactor design concepts which operate at a nominal power output range of 20 to 50 kWe are described. Details of the neutronic, thermionic, thermal hydraulics and shielding performance are presented. Due to the strong absorption of thermal neutrons by natural tungsten, and the large amount of that...
Resource Type:: Masters Thesis

Creator:: Lewis, Bryan R.
Abstract:: An overall systems design code was developed to model an advanced in-core thermionic energy conversion based nuclear reactor system for space applications at power levels of 10 to 50 kWe. The purpose of this work was to provide the overall shell for the systems code and to also provide the...
Resource Type:: Masters Thesis

Creator:: Van Horn, Matthew A.
Abstract:: The Very High Temperature Reactor (VHTR) design was one of six designs chosen for development under the Generation IV initiative. Thermal mixing of the coolant at the exit of the reactor has been a common concern for VHTR reactor designs. Thermal mixing processes are commonly investigated through the use of...
