(Fission product transport experiments (HFR-B1))

Description: Travel to the JRC Petten was for the purpose of discussing the HFR-B1 experiment and post irradiation activities. Technical assessment of the experiment strongly supports the concept of enhanced fission gas release at temperatures above 1100{degree}C, the extensive release of stored fission gas at water vapor levels postulated in accident scenarios, an increase in the steady-state fission gas release under hydrolyzing conditions, and an increase in gas release during thermal cycling.

Study of mechanisms of hydrogen diffusion in separation devices. Third annual report, 1979-1980

Description: The main results are in the following three areas: (1) examination of a diffusion model for PdH system, (2) connection between the diffusion model and other physical models, (3) related problems. Advances made during the third year of this project, particularly in understanding the physical model for hydrogen diffusion, make it possible to begin to meet some of the long-range objectives described in the initial proposals of 1977-1978.

Effects of pulsed dual-ion irradiation on phase transformations and microstructure in Ti-modified austenitic alloy

Description: The influence of pulsed 4 MeV Ni ion bombardment, with and without simultaneous helium injection, has been explored in a low swelling, Ti-modified austenitic stainless steel. Irradiations were carried out to 70 dpa at 950/sup 0/K; the pulsing frequencies were either 60 s on/off or 1 s on/off. Compared to continuous irradiation, pulsing caused a decrease in the interstitial loop diameter at 1 dpa, although at higher doses the overall dislocation density was not affected. Pulsing and helium both … more

Safety evaluation for the inner canister closure station

Description: The Inner Canister Closure Station (ICCS), built by Remote Technology Corporation, will be operability tested. The ICCS is used to remotely leak test Inner Canister Closures (ICC's) and replace ICC's that are not water tight. After operability testing, the ICCS will be inspected and sent to the 717-F mock-up shop for remotability demonstration and dimensional checks, then installed in the Vitrification Building, 221-S. An analysis of potential safety hazards, equipment safety features, and proc… more

Experimental determination of kerma factors at E/sub n/ approx. = 15 MeV

Description: Experimental values for the kerma per unit fluence at the neutron energy, E/sub n/ = 15 MeV, have been determined for graphite, Mg, and Fe. Ion chambers of small size with walls of these materials were employed, and were filled with a variety of gases--N/sub 2/, CO/sub 2/, Ne, Ar, Kr, and Xe. A calibrated neutron source was employed, allowing a straightforward determination of the kerma per unit fluence.

Silicon-on-ceramic process: silicon sheet growth and device development for the large-area silicon sheet task of the Low-Cost Solar Array Project. Annual report No. 5, September 29, 1979-September 30, 1980

Description: The objective of this research is to investigate the technical feasibility of producing solar-cell-quality sheet silicon to meet the DOE 1986 cost goal of 70 cents/watt. The silicon-on-ceramic approach is to coat a low-cost ceramic substrate with large-grain polycrystalline silicon by unidirectional solidification of molten silicon. Results are reported. A new silicon-coating system, SCIM-II, was designed and constructed. A design strategy to avoid buckling and breaking of substrates has been f… more

Rayleigh-Taylor instability in compressible fluids

Description: This is a report of the progress during the past year of the shock-tube study of the Richtmyer-Meshkov instability, initiated under the sponsorship of the Lawrence Livermore National Laboratory in September, 1982. The purpose of this research program, as stated in the original proposal, is: to investigate the nonlinear processes initiated by shock wave interaction with gas-gas interfaces. In particular, the nonlinear stage of shock-initiated Rayleigh-Taylor instability, the secondary instabilit… more

Sampling a two-phase geothermal brine flow for chemical analysis

Description: An experiment designed primarily to define the problems associated with sampling the two-phase flow in a pipeline of geothermal brine is described. Analyses reported for 26 samples include chemical composition, oxidation potential, pH, density, and total solids. Changes in brine composition as the well operated during a four-week period are evaluated. The apparatus and techniques used for sampling are described and evaluated. (auth)

Cost-Benefit Analysis of Advanced, Sanitary Sewage Treatment at Rocky Flats

Description: A small, secondary treatment plant for processing sanitary wastes was upgraded by the addition of tertiary treatment (chemical treatment and final clarification) and mixed-media filtration. Operational data showed that the tertiary treatment significantly reduced pollutants. Filtration further reduced suspended solids significantly and removed some additional phosphorus; however, no additional reduction in total oxygen demand or in nitrogen was noted. Detailed analyses of costs for construction… more

Experimental study of interactions of highly charged ions with atoms at keV energies

Description: This Progress Report describes the experimental work carried out, and the work in progress, at the Cornell EBIS Laboratory during the period 7/1/1991 to 6/30/1992. During this period, a number of experiments were carried out. The absolute values of the total, one, two and three electron transfer cross sections for highly charged argon ions (8{le}q{le}16) colliding with argon at 2.3 qkev laboratory energy were measured. The distribution of recoil ions and molecular fragments formed in highly cha… more

Study of the effects of accidentally released carbon/graphite fibers on electric power equipment. Program final report, June 5, 1978-June 5, 1980

Description: The program to study the effect of accidentally released carbon fibers on electrical power equipment consisted of determining the vulnerability of system outage rates to carbon fiber contamination, and performing tests to quantitize the contamination required to cause flashover of external insulation. Part One of this final report describes an assessment of the vulnerability of power systems to accidentally released fibers from a composite burn. The assessment describes the effect of carbon fib… more

Theoretical studies involving candidate VIA laser systems

Description: Theoretical studies supporting the Livermore photolytic Group VIA laser project were initiated early in 1977. Results of numerous theoretical studies which deal with the photolysis process, losses in the upper laser level and the photolytic pumps are described. Results of ab initio calculations on OCS have been used to assign the electronic states and to analyze the photolysis process. Photoionization cross sections of the upper laser level have been calculated for O(/sup 1/S), S(/sup 1/S) and … more

Biological Conversion of Synthesis Gas

Description: Syngas is known to contain approximately 1 percent H[sub 2]S, along with CO[sub 2], C0[sub 2], H[sub 2] and CH[sub 4]. Similarly, the syngas may become contaminated with oxygen, particularly during reactor start-up and during maintenance. Previous studies with the water-gas shift bacterium Rhodospirillum rubrum have shown that the bacterium is tolerant of small quantities of oxygen, but the effects of oxygen on CO-consumption are unknown. Similarly, R. rubrum is known to be tolerant of H[sub 2]… more
