Heavy-Section Steel Technology Program fracture issues

Description: Large-scale fracture mechanics tests have resulted in the identification of a number of fracture-technology issues. Identification of additional issues has come from the reactor vessel materials-irradiation test program and from reactor operating experience. This paper provides a review of fracture issues with an emphasis on their potential impact on a reactor vessel pressurized-thermal-shock (PTS) analysis. Mixed-mode crack propagation emerges as a major issue, due in large measure to the poor… more

An overview of seismic-induced hydrodynamic phenomena in LMR reactor tanks

Description: Liquid metal reactors (LMTs) usually contain a huge volume of liquid sodium as reactor coolant. Since most reactor components are submerged in the sodium coolant, the seismic-induced hydrodynamic effects are of great importance in the design of LMR reactor components. Because LMRs operate at low pressures, the reactor components are made of thin-walled structures. Of interest in reactor design, in particular, are the hydrodynamic pressures imposed on various components, such as the reactor vess… more

Wear Reduction Systems Liquid Piston Ring

Description: The overall objective of the program was to demonstrate the technical feasibility of achieving an acceptable wear rate for the cylinder liner, piston, and piston rings in a coal/water-slurry-fueled engine that utilized the concept of a liquid piston ring above the conventional piston rings and to identify technical barriers and required research and development. The study included analytical modeling of the system, a bench study of the fluid motion in the liquid piston ring, and a single-cylind… more

Examination of coherency criteria for high velocity jets

Description: An examination of a coherency criteria for high velocity jets is discussed in this paper. An analysis of the classical Pugh, Eichelberger, Rostoker jetting theory is used to develop an equation that defines the maximum coherent jet velocity as a function of the liner material sound speed, the liner beta angle, and the magnitude direction of the liner collapse velocity vector. The liner material sound speed is assumed to be the liner material shock velocity at the time of liner material collapse… more

Fate and transport of constituents leaked from Tank 241-A-105

Description: Following a January 28, 1965 sudden steam release in Tank 241-A-105, the carbon steel liner of the tank was noted to have bulged to a maximum height of about 8.5 feet (2.6 meters). Most of this bulging likely resulted from the January 28, 1965 incident. But available data indicate that some bulging during an earlier leak in 1963 when waste was being added to the tank may have contributed. By March 8, 1965, increases in radiation in the 14-05-03 leak detection lateral indicted that fluids had es… more

Waste drum gas generation sampling program at Rocky Flats during FY 1989

Description: Rocky Flats Plant transuranic waste drums were sampled for gas composition. Glass, metal, graphite, and solidified inorganic sludge transuranic waste forms were sampled. A vacuum system was used to sample each layer of containment inside a waste drum, including individual waste bags. G values were calculated for the waste drums. G(H{sub 2}) was below 0.6 and G(Total) was below 1.3 for all waste forms discussed in this report. 5 refs., 3 figs., 3 tabs.

Structural analysis of an underground reinforced concrete waste storage tank due to over-pressurization

Description: This paper presents the results of a structural analysis performed by use of the finite element method in determining the pressure-carrying capacity of an underground tank which contains nuclear wastes. The tank and surrounding soil were modeled and analyzed using the ABAQUS program. Special emphases were given on determining the effects of soil-containment interaction by employing Coulomb friction model. The effect of material properties was investigated by considering two sets of stress-strai… more

Data Summary of Municipal Solid Waste Management Alternatives, Volume 8: Appendix F--Landfills

Description: While the preceding appendices have focused on the thermochemical approaches to managing municipal solid waste (MSW), this appendix and those that follow on composting and anaerobic digestion address more of the bioconversion process technologies. Landfilling is the historical baseline MSW management option central to every community's solid waste management plan. It generally encompasses shredfills, balefills, landfill gas recovery, and landfill mining. While landfilling is virtually universal… more

Hanford Permanent Isolation Barrier Program: Asphalt technology data and status report - FY 1994

Description: The asphalt layer within the Hanford Permanent Isolation Barrier (HPIB) is an important component of the overall design. This layer provides a RCRA equivalent backup to the overlying earthen layers in the unlikely event that these layers are not able to reduce the infiltration rate to less than 0.05 cm/yr. There is only limited amount of information on using asphalt for a moisture infiltration barrier over the long times required by the HPIB. Therefore, a number of activities are under way, as … more

Vanadium-lined HT9 cladding tubes

Description: Argonne National Laboratory`s Integral Fast Reactor (IFR) is an advanced liquid-metal-cooled reactor (ALMR) that uses a metallic (U-Pu-Zr alloy) fuel material in a steel cladding. The intimate contact between the fuel and fission products with the cladding at reactor operating temperatures (<600{degrees}C) can lead to chemical interaction and potential degradation of the cladding. One possible way to minimize the diffusion of the fuel and fission products into the steel cladding during irradiat… more

Adsorption of aniline and toluidines on montmorillonite: Implications for the disposal of shale oil production wastes

Description: Bentonite clay liners are commonly employed to mitigate the movement of contaminants from waste disposal sites. Solid and liquid waste materials that arise from the production of shale oil contain a vast array of organic compounds. Common among these compounds are the aromatic amines. in order to assess the ability of clay liner material to restrict organic compound mobility, the adsorption of aniline and o-, m-, and p-toluidine on Ca{sup 2+} - and K{sup +}-saturated Wyoming bentonite was inves… more

Leachate treatment system using constructed wetlands, Town of Fenton sanitary landfill, Broome County, New York. Final report

Description: Municipal sanitary landfills generate leachate that New York State regulations require to be collected and treated to avoid contaminating surface water and groundwater. One option for treating leachate is to haul it to municipal wastewater treatment facility. This option may be expensive, may require excessive energy for transportation, and may require pretreatment to protect the receiving facility`s processes. An alternative is on-site treatment and discharge. Personnel from the Town of Fenton… more

Estimates of Durability of TMI-2 Core Debris Canisters and Cask Liners

Description: Core debris from the Three Mile Island-2 (TMI-2) reactor is currently stored in stainless steel canisters. The need to maintain the integrity of the TMI-2 core debris containers through the period of extended storage and possibly into disposal prompted this assessment. In the assessment, corrosion-induced degradation was estimated for two materials: type 304L stainless steel (SS) canisters that contain the core debris, and type 1020 carbon steel (CS) liners in the concrete casks planned for con… more
