Radiotoxicity of Injected SR89 for Rats, Mice, and Rabbits. Part II. Metabolism and Organ Distribution

Description: Mice, rats and rabbits excreted Sr89-Sr90 very rapidly following intraperitoneal or intravenous administration. The greatest part of the excretion took place during the first three days, and by 10-15 days virtually no more of the retained strontium was excreted.

Correlation of radionuclide leachabilities with microstructures of glasses containing Savannah River Plant waste

Description: Leachabilities of cesium and strontium from the glass matrices were correlated with the microstructures of glasses containing waste sludge from two SRP waste tanks. All sludge components, except mercury which volatilized, were completely soluble in the melt, but small amounts of crystalline iron oxide precipitated during cooling. These precipitates were less leachable than the glass matrix. Even though the compositions of the two sludges that were tested were similar, glass containing one of th… more

Evaluation of zeolite mixtures for decontaminating high-activity-level water at the Three Mile Island Unit 2 Nuclear Power Station

Description: Mixtures of Linde Ionsiv IE-96 and Ionsiv A-51 were evaluated for use in the Submerged Demineralizer System (SDS) that was installed at the Three Mile Island Unit 2 Nuclear Power Station to decontaminate approx. 2780 m/sup 3/ of high-activity-level water. The original SDS flowsheet was conservatively designed for removal of cesium and strontium and would have required the use of approx. 60 SDS columns. Mixed zeolite tests were made on a 10/sup -5/ scale and indicated that the appropriate ratio … more

Rb--Sr, K--Ar, and fission-track geochronological studies of samples from LASL drill holes GT-1, GT-2, and EE-1

Description: Geochronological investigations using the Rb-Sr, K-Ar, and fission-track methods have been completed on core samples from the three LASL deep drill holes, GT-1, GT-2, and EE-1. This work indicates a complex history for these Precambrian rocks beginning with a metamorphic event at 1.66 b.y. which generated the gneisses and schists from older sedimentary and igneous rocks. The metamorphic complex was intruded by at least two different magmas at 1.3--1.4 b.y. producing thin felsic dikes and a majo… more

Electron correlation in atoms from photoelectron spectroscopy

Description: The photoelectron spectrum of an atom A yields the eigenenergies of the ion A/sup +/. Additional satellite peaks arise because of electron correlation effects. Peaks observed in spectra from Ca, Sr, Zn, Cd, and Hg have been attributed to initial-state configuration interaction, while final-state configuration interaction gives satellite peaks in a Ba spectrum. The neon ls ''shakeup'' spectrum is a result of both effects.

Study of methods for removing strontium, plutonium, and ruthenium from Savannah River Plant waste supernate

Description: As a part of long-term waste management studies at the Savannah River Laboratory, tests were made to study removal of strontium, plutonium, and ruthenium from simulated and actual waste supernates. Plutonium was sorbed by Duolite ARC-359 ion exchange resin, the same resin that is used to remove cesium from waste supernate. Strontium was removed from supernate by sorption on a chelating resin Chelex 100, or by precipitation as Sr/sub 3/(PO/sub 4/)/sub 2/. Activities of /sup 137/Cs, /sup 90/Sr, a… more

In-situ nitrite analysis in high level waste tanks

Description: The Savannah River Site produces special nuclear materials used in the defense of the United States. Most of the processes at SRS are primarily chemical separations and purifications. In-situ chemical analyses help improve the safety, efficiency and quality of these operations. One area where in situ fiberoptic spectroscopy can have a great impact is the management of high level radioactive waste. High level radioactive waste at SRS is stored in more than 50 large waste tanks. The waste exists … more

Hanford waste encapsulation: strontium and cesium. [SrF/sub 2/ encapsulated in Hastelloy C-276 and CsCl in stainless steel 316L]

Description: The strontium and cesium fractions separated from high radiation level wastes at Hanford are converted to the solid strontium fluoride and cesium chloride salts, doubly encapsulated, and stored underwater in the Waste Encapsulation and Storage Facility (WESF). A capsule contains approximately 70,000 Ci of /sup 137/Cs or 70,000 to 140,000 Ci of /sup 90/Sr. Materials for fabrication of process equipment and capsules must withstand a combination of corrosive chemicals, high radiation dosages and f… more

Experimental Determination of Contaminant Metal Mobility as a Function of Temperature, Time and Solution Chemistry

Description: During the FY96-FY99 funding cycle we examined the uptake of aqueous strontium onto goethite, kaolinite, and amorphous silica surfaces as a function of pH, total strontium, and temperature. Our overall goal was to produce a mechanistic sorption model that can be used in reaction-transport calculations to predict the mobility and attenuation of radioactive strontium ({sup 90}Sr)in the environment. Our approach was to combine structural information derived from EXAFS analysis together with macros… more

Towards High Performance p-Type Transparent Conducting Oxides

Description: P-type transparent conductive oxides would have potential applications in photovoltaics, transparent electronics and organic opto-electronics. In this paper we present results on the synthesis of Cu2SrO2, a p-type transparent conducting oxide, by a chemical solution route as well as the conventional pulse laser deposition (PLD) method. For Cu2SrO2 by the chemical solution route, samples were made by spraying deposition on quartz substrates using an aqueous solution of Copper formate and Stronti… more

Development of cementitious grouts for the incorporation of radioactive wastes. Part 2. Continuation of cesium and strontium leach studies. [Hydrofracture]

Description: Additional leach studies were completed on the leachability of cesium and strontium from simulated hydrofracture grout. These studies followed the test method proposed by IAEA or a modification which exposed smaller specimens with a higher surface-to-volume ratio to a larger volume of leachant. Results showed that the amount of cesium or strontium leached from the grout varied directly with the degree of drying during curing and inversely with the time of curing. The leachability also depends o… more

Radiological Conditions on Rongelap Atoll: Diving and Fishing on and Around Rongelap Atoll

Description: Rongelap Atoll experienced close-in ''local fallout'' from nuclear weapons tests conducted by the United States (1946-58) in the northern Marshall Islands. Most of the radiation dose delivered to Rongelap Island residents during the 1950s was from radioactive elements that quickly decayed into non-radioactive elements. Since 1985, the Lawrence Livermore National Laboratory (LLNL) has continued to provide monitoring of radioactive elements from bomb testing in the terrestrial and marine environm… more

Evaluation of concrete as a matrix for solidification of Savannah River Plant waste

Description: The properties of concrete as a matrix for solidification of Savannah River Plant (SRP) high-level radioactive wastes were studied. In an experimental, laboratory-scale program, concrete specimens were prepared and evaluated with both simulated and actual SRP waste sludges. Properties of concrete were found adequate for fixation of SRP wastes. Procedures were developed for preparation of simulated sludges and concrete-sludge castings. Effects of cement type, simulated sludge type, sludge loadin… more

Photoemission and Photoabsorption Investigation of the Electronic Structure of Ytterbium Doped Strontium Fluoroapatite

Description: X-ray photoemission and x-ray photoabsorption were used to study the composition and the electronic structure of ytterbium doped strontium fluoroapatite (Yb:S-FAP). High resolution photoemission measurements on the valence band electronic structure was used to evaluate the density of occupied states of this fluoroapatite. Element specific density of unoccupied electronic states in Yb:S-FAP were probed by x-ray absorption spectroscopy (XAS) at the Yb 4d (N{sub 4,5}-edge), Sr 3d (M{sub 4,5}-edge)… more

High-T/sub c/ superconductor and its use in superconducting magnets

Description: Many of the proposed uses for the high-T/sub c/ superconductor involve the creation of a magnetic field using superconducting coils. This report will assess what is known about the high-T/sub c/ superconductors and take a realistic look at their potential use in various kinds of superconducting magnets. Based on what is known about the high-T/sub c/ superconductors, one can make a ''wish list'' of things that will make such materials useful for magnets. Then, the following question is asked.
