This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Construction of the UHTREX facility is about 63% complete and is about 5% behind scheule based on a completion date of February 1964. A series of 84 experimental runs were made in the half-scale flow model of the UHTREX core to investigate the degree of flow unbalance between the 312 fuel channels. It was shown that an initial source of strength of about 103 neutrons/sec is to be expected when UHTREX is fueled with 7 kg of enriched uranium (93.5% U235, 1% U 94, and 5.5% U238) loaded in graphite by solution impregnation. In an effort to refine the calculated worths of shutdown rods, several two-dimensional IBM 7090 codes, applying both neutron transport and diffusion theory, were used. To simplify the analysis of the UHTREX system's dynamic behavior, the major components for heat exchange are represented by three or four axial lump models. The UHXCOM simulation program solves the basic system differential equations on the IBM 7090 and produces time plots of different operating variables such as reactor power, period, gas temperature, etc. A separate analysis is being made with a frequency domain IBM 7090 program that solves equations written in terms of the Laplace transform variable. Very satisfactory performance was achieved with a process gas chromatograph. The second of two single-stage diaphragm compressors was operated for 20 hr in a shakedown run. Two helium blowers operating on hydrodynamic gas bearings were developed. (M.C.G.).

This book was released on 1961 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The detailed design of the reactor proper was essentially completed and preparations were made for procurement of the carbon components and the pressure vessel. Design of the UHTREX facility has progressed to Titie lI. Design information is included on copper oxide beds and molecular sieves for gas cleanup. In other work, irradiation of capsules containing UHTREX fuel elements is reported along with fuel recycle research. (J.R.D.) 9578(Faye unscannable abstract).

This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Pressure tests of the reactor vessel showed that stresses were within allowable limits for the design pressure of 550 psig. Tests of the fuel loading mechanism are also reported in which 300,000 cycles were completed. Results of an investigation of core corrosion damage led to the conclusion that for prolonged operation of a graphite reactor in the ultrahigh-temperature range, the average CO2 level must be limited to approximately 1 ppm. Developmental work on the coolant system is reported, and results of an analyeis of the reactor and cooling system using an IBM 7090 program are discussed. Tests of the gas cleanup system are reported in which CuO was successfully used. Calculations concerning shielding showed that an extra 2 in. thickness of Pb should be added to the inside face between the water panels and the concrete to reduce the temperature gradient and the associated tensile etress below 1000 psi in the concrete walls. It is noted that the reactor facility was about 14% complete at the end of the reporting period. (J.R.D.).

This book was released on 1962 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: UHTREX utilizes a high-temperature, He-cooled, graphite moderated reactor employing unclad, refractory fuel elements. The reactor is designed to produce a maximum thermal power of 3 Mw and a maximum exit He temperature of 2400 deg F. The purpose of the experimert is to evaluate the advantages of the simple fuel against the disadvantages of the associated operation of a contaminated coolant loop. The mechanical and nuclear design of the reactor and related apparatus are described, discussed, and evaluated from the standpoint of hazards associated with conduct of the experiment. The building design and characteristics of the site are also examined from the same standpoint. The probable effects of operational errors and component failures are studied. The conseqnences of credible accidents are not considered to be catastrophic for either operating personnel or personnel in surrounding areas.
