The Concentration of Peroxide in Uranyl Sulfate Solutions at Incipient Precipitation

Description: The concentrations of peroxide in uranyl sulfate solutions at incipient precipitation of uranium peroxide were determined over a temperature interval from 79 to 114'C. The results of the experimental observations have been used to calculate a self-consistent set of numerical parameters that are related to the equilibrium of hydrogen peroxide, uranyl ion and hydrogen ion.

Reactor Physics of Teapot. Part V, Proposed Stability Experiment

Description: Technical report of an investigation concerning two methods of determining the stability of boiling reactors. It was found that the one involving a rapid reactivity change (such as rapid removal of a rod) is the better method. In the experiment involved, the reactor flux and rate of reactivity addition over periods of time are required. It is also desirable that the average fluid density be measured. Means of providing rapid reactivity changes are available, and methods involving rod movement a… more

Protection of Carbon Steel from Atmospheric Corrosion

Description: The NPR design calls for carbon steel to be the major constituent in the reactor coolant piping system. The piping and its associated fittings will, in all likelihood, be exposed to atmospheric weather conditions during the period of reactor construction. This type of exposure causes rusting. From experience gained during the startup of KER Loop 1 it is expected that there will be initially high NPR coolant activity levels. The high activity during the startup of KER Loop 1 was partially caused… more

3 Plant Radiation Study Interim Report #5- Part II Data on Gamma Shielding of Special Plutonium Samples

Description: The calculation of shielding the thickness for plutonium is complicated by the many different energies represented in the gamma radiation emitted during decay of the plutonium isotopes. Dose rate predictions are also frequently confused by gamma from varying content of fission product impurities in the plutonium, as well as other gamma radiation induced through alpha and neutron particle absorption within the source material or its environment. After assumptions are made for these many factors… more

Limitations for Existing Storage Tanks for Radioactive Wastes from Separations Plants

Description: Continued process improvements in the separation plants provide an incentive for economics in waste storage costs by utilizing existing facilities to their maximum capability consistent with the radiological hazards involved. The major improvements have reduced waste volumes resulting in increased fission product concentration and energy potential. Analyses have been made to determine the effect of this change on the integrity of the existing structures.

The X-Ray Spectra of the Last-Row Elements

Description: Abstract: X-ray energy level diagrams as given in the literature are tabulated for radium, thorium and uranium. A level scheme for protoactinium is derived from the published data. After a brief review of the use of X-ray data in studying outer electronic structure, it is pointed out that differences in the X-ray spectra should exist depending on whether the outer electrons are in f or d orbitals. The observed separation of the OI and OII levels in thorium and uranium indicated that the f lev… more

The Enhancement of Acidity of Very Weak Acids in Tertiary Butyl Alcohol

Description: Technical report. From Abstract : "The acidity of a solution of acid, HX, and salt, MX, is affected by both the concentration of X- and M+ owing to incomplete dissociation of the salt, MX. it was possible to increase the acidity of a solution of 2,6-di-tert-butylphenol - tetrabutylammonium 2,6-di-tert-butylphenolate relative to a dilute solution of tetrabutylammonium hydroxide by increasing the tetrabutylammonium bromide content. This indicates that the dissociation constant of the hydroxide ba… more

Program plan for the Brayton Isotope Power System. Phase I. Design, fabrication and test of the Brayton Isotope Power System

Description: Phase I of an overall program for the development of a 500 to 2000 W(e) (EOM), 7-y life, power system for space vehicles is discussed. The system uses a closed Brayton dynamic system to convert energy from an isotope heat source at a net efficiency greater than 25 percent. This first phase, a 35-month effort, is for the conceptual design of a 1300 W(e), 450 lb flight system and the design, fabrication, and test of a ground demonstration system. The flight system will use, for the baseline desig… more

Remediating biofouling of reverse osmosis membranes

Description: Several potential additives and the use of influent pH adjustment were examined to remediated the biofouling problem of the ETF reverse osmosis (RO) system. Tests were conducted with simulated RO feed containing salt, metal hydroxides and bacteria. The addition of sodium hexametaphosphate (SHMP), sodium bisulfite, and adjusting the influent pH to 3 were each successful in reducing the RO biofouling. Little or no benefit was found from the use of a biofilm remover (Filmtec Alkaline Cleaner) or t… more

China's Status as a Nonmarket Economy (NME)

Description: This report discusses China's classification by the World Trade Organization (WTO). China contends that language in its WTO accession protocol required all WTO members to terminate their use of the alternative methodology; the United States and other WTO members argue that that the WTO language did not automatically obligate them to extend market economy status (MES) to China.

Large eddy simultations of the atmospheric boundary layer east of the Colorado Rockies

Description: Large eddy simulation, LES, has often been carried out for the idealized situation of a simple convective boundary layer. Studies of dual Doppler radar and aircraft data from the Phoenix II experiment indicate that the boundary layer of the Colorado High Plains is not a purely convective boundary layer and it is influenced by the mountains to the west. The purpose of this study is to investigate the atmospheric boundary layer on one particular day on the Colorado High Plains. This research appl… more
