Antiproton driven microfission-fusion on closer inspection

Description: A closer look at the energetics of antiproton annihilation in real systems, coupled to hydrodynamics, materials strength, particle transport, equations of state, and related interactions is necessary to assess ultimate viability. The systematics of antiproton microfission-fusion are the subject of this analysis, as well as technology constraints.

Transport of radon and thoron at the earth's surface

Description: This report covers progress under the current funding period 1 Jan 1992 to 1 Jan 1993 and presents the continuation proposal for 1 Jan 1993 to 1 Jan 1994. The previous progress report was submitted in June 1991, so activities during the last half of 1991 will also be included. Our major activities over the last year have continued to focus on measurements and modeling of the disequilibrium of radon and thoron progeny outdoors, and analysis of data on indoor thoron and thoron progeny.

Beam characterization at the Neutron Radiography Facility (NRAD)

Description: An ongoing project to characterize the neutron beams at the Neutron Radiography Reactor (NRAD) is described in this paper. The effort has consisted of computer modelling with three dimensional diffusion theory to obtain a trail spectrum, foil activation measurements, and the use of SAND-II unfolding code. It was expected and found that diffusion theory will underpredict the fast flux. However, it is claimed that precise characterization of the entire spectrum is not necessary for comparisons am… more

Uranium concentrations in asparagus

Description: Concentrations of uranium were determined in asparagus collected from eight locations near and ten locations on the Hanford Site southcentral Washington State. Only one location (Sagemoor) had samples with elevated concentrations. The presence of elevated uranium in asparagus at Sagemoor may be explained by the elevated levels in irrigation water. These levels of uranium are comparable to levels previously reported upstream and downstream of the 300-FF-1 Operable Unit on the Hanford Site (0.000… more

HLNC calibration and application to waste measurement

Description: Using the established equations governing the counts and the underlying nuclear parameters involved in neutron coincidence measurements, the calibration procedure used in calculating the effective Pu{sup 240} mass in plutonium bearing samples is carefully reexamined and restructured in a physically and mathematically consistent form. The characteristics of this approach are described and its application to existing data illustrated. The implications for waste measurements are discussed.

Characterizing and improving passive-active shufflers for assays of 208-Liter waste drums

Description: A passive and active neutron shuffler for 208-L waste drums has been used to perform over 1500 active and 500 passive measurements on uranium and plutonium samples in 28 different matrices. The shuffler is now better characterized and improvements have been implemented or suggested. An improved correction for the effects of the matrix material was devised from flux-monitor responses. The most important cause of inaccuracies in assays is a localized instead of a uniform distribution of fissile m… more

Detection and differentiation of contamination through a comparison of observed levels in historical environmental sampling data

Description: In summarizing more than a decade of environmental monitoring data from the Hanford Site, we noted that grouping data by analysis, rather than by medium, enhanced visual as well as statistical interpretations. By plotting running-averages of individual radionuclides on the same graph, for different media, we evaluated environmental trends to determine whether or not a local impact had been observed. This approach may enhance ones ability to interpret environmental monitoring data collected foll… more

Confirming criticality safety of TRU waste with neutron measurements and risk analyses

Description: The criticality safety of {sup 239}Pu in 55-gallon drums stored in TRU waste containers (culverts) is confirmed using NDA neutron measurements and risk analyses. The neutron measurements yield a {sup 239}Pu mass and k{sub eff} for a culvert, which contains up to 14 drums. Conservative probabilistic risk analyses were developed for both drums and culverts. Overall {sup 239}Pu mass estimates are less than a calculated safety limit of 2800 g per culvert. The largest measured k{sub eff} is 0.904. T… more

Relative yields of U-235 fission products measured in a high level radioactive sludge at Savannah River Site

Description: This paper presents measurements of the concentrations of 42 of the long-lived U-235 fission products in a high-level radioactive waste sludge stored at Savannah River Site. The 42 fision products make up 98% of the waste sludge. We used inductively coupled plasma-mass spectroscopy for the analysis. The relative yields for most of the fission products are in complete agreement with the known relative yields for the beta decay chains of the two asymmetric branches of the slow neutron fission of … more

Revisions to the hydrogen gas generation computer model

Description: Waste Management Technology has requested SRTC to maintain and extend a previously developed computer model, TRUGAS, which calculates hydrogen gas concentrations within the transuranic (TRU) waste drums. TRUGAS was written by Frank G. Smith using the BASIC language and is described in the report A Computer Model of gas Generation and Transport within TRU Waste Drums (DP- 1754). The computer model has been partially validated by yielding results similar to experimental data collected at SRL and … more

Field studies of streamflow generation using natural and injected tracers on Bickford and Walker Branch Watersheds

Description: Field studies of streamflow generation were undertaken on two forested watersheds, the West Road subcatchment of Bickford Watershed in central Massachusetts and the West Fork of Walker Branch Watershed in eastern Tennessee. A major component of the research was development of a two-stage methodology for the use of naturally-occurring {sup 222}Rn as a tracer. The first of the two stages was solving a mass-balance equation for {sup 222}Rn around a stream reach of interest in order to calculate Rn… more

Preliminary remedial action objectives for the Tank 16 groundwater operable unit

Description: Tank 16 is a High Level Radioactive Waste tank in the H-Area Tank Farm on the Savannah River Site that was placed into service in May 1959. A leak was detected in one of the construction weld joints while the tank was being filled. Before jet evacuation of the tank waste was completed, the leak overflowed the annulus pan and an estimated 16 to 700 gallons of waste escaped to the environment (soil and groundwater) over a six hour period contaminating approximately 1,600--70,000 cubic feet of soi… more

Electron-beam processing of kilogram quantities of iridium for radioisotope thermoelectric generator applications

Description: Iridium alloys are used as fuel-cladding materials in radioisotope thermoelectric generators (RTGs). Hardware produced at the Oak Ridge National Laboratory (ORNL) has been used in Voyagers I and 2, Galilee, and Ulysses spacecraft. An integral part of the production of iridium-sheet metal involves electron-beam (EB) processing. These processes include the degassing of powder-pressed compacts followed by multiple meltings in order to purify 500-g buttons of Ir-0.3% W alloy. Starting in 1972 and c… more

Remediation of uranium mill tailings by an integrated biological and chemical process

Description: Dilute calcium chloride brine solution was found to be effective in the solubilization of toxic heavy metals and long half-life radionuclides (Th-230, Ra-226 and Pb-210) from uranium ores and mill tailings. The recovery of heavy metals and radionuclides from uranium mill tailing effluents was studied with calcium alginate beads. The maximum cadmium and zinc uptakes by calcium alginate beads were determined to be 2.8 [times] 10[sup [minus]3] and 2.3 [times] 10[sup [minus]3] mol/dry weight of alg… more

[Analysis of DNA damage and mutations induced by radon daughter products]

Description: In order to understand the genetic and somatic risks associated with exposure to radon and its daughter products, it is important to characterize those lesions that lead to mutation induction and carcinogenesis. The effect of exposure to the radon daughter (212)Bi has been analyzed in 4 CHO cell lines, CHO-KL, xrs-5, AA8 and EM9. These cell lines have different radiation sensitivities and different abilities to rejoin radiation-induced DNA strand breaks. Three endpoints have been examined in th… more
