Creep-Fatigue Life Prediction for Different Heats of Type 304 Stainless Steel by Linear-Damage Rule, Strain-Range Partitioning Method, and Damage-Rate Approach

Description: The creep-fatigue life results for five different heats of Type 304 stainless steel at 593 degrees C (1100 degrees F), generated under push-pull conditions in the axial strain-control mode, are presented. The life predictions for the various heats based on the linear-damage rule, strain-range partitioning method, and damage-rate approach are discussed. The appropriate material properties required for computation of fatigue life are also included.

Critical Survey on Electrode Aging in Molten Carbonate Fuel Cells

Description: To evaluate potential electrodes for molten carbonate fuel cells, we reviewed the literature pertaining to these cells and interviewed investigators working in fuel cell technology. In this critical survey, the effect of three electrode aging processes - corrosion or oxidation, sintering, and poisoning - on these potential fuel-cell electrodes is presented. It is concluded that anodes of stabilized nickel and cathodes of lithium-doped NiO are the most promising electrode materials for molten caā€¦ more

Cs--U--O Phase Diagram and its Application to Uranium--Plutonium Oxide Fast Reactor Fuel Pins

Description: Portions of the cesium-uranium-oxygen system have been investigated between 873 and 1273Ā°K and a phase diagram has been constructed using our data and the data of other workers in the field. Thermodynamic and kinetic data have been used to examine the reactions that occur in fast-reactor fuel pins between fission-product cesium and the uranium oxide blanket. It was concluded that at the low oxygen potentials existing at the interface between the uranium-plutonium mixed-oxide and the uranium oxiā€¦ more

The Current Status of Fusion Reactor Blanket Thermodynamics

Description: The available thermodynamic information is reviewed for three categories of materials that meet essential criteria for use as breeding blankets in deuterium-tritium (D-T) fueled fusion reactors: liquid lithium, solid lithium alloys, and lithium-containing ceramics. The leading candidate, liquid lithium, which also has potential for use as a coolant, has been studied more extensively than have the solid alloys or ceramics.

Cyclic-Deformation Resistance of Weld-Deposited Type 16-8-2 Stainless Steel at 593 Degrees C

Description: This report presents results from an investigation on the creep-fatigue and cyclic-deformation of Type 16-8-2 (16% Cr-8% Ni-2% Mo) stainless steel weld metal. Tests were conducted in air at 593 degrees C and a strain rate of 0.004 sā»Ā¹. Comparisons with data for Type 316 stainless steel base metal indicated that the weld metal has significantly longer fatigue lives for several tension hold-time tests. This is attributed to the fine duplex microstructure of the weld metal that inhibits the growthā€¦ more

Decommissioning Alternatives for the West Valley, New York, Fuel Reprocessing Plant

Description: The methodology and numerical values of NUREG-0278 were applied to four decommissioning alternatives for the West Valley Fuel Reprocessing Plant. The cost and impacts of the following four alternatives for the process building, fuel receiving and storage, waste tank farm, and auxiliary facilities were assessed: (1) layaway, (2) protective storage, (3) preparation for alternate nuclear use, and (4) dismantlement. The estimated costs are 5.7, 11, 19, and 31 million dollars, respectively.

Decomposition of Calcium Sulfate : a Review of the Literature

Description: One of the important issues related to fluidized bed combustion of fossil fuels is the subsequent handling and/or treatment of the partially sulfated lime material removed from the combustor. One alternative would be to regenerate the sulfated additive to recover the sulfur, which would be stored for use, and lime that would be recycled for reuse in the combustor. It is the purpose of this report to review the development of regeneration technology which has progressed rather slowly as comparedā€¦ more

Deflection-Coverage Relationship for Flexible Pavements

Description: Summary: "This study was conducted for the purpose of developing a relationship between elastic pavement deflection and pavement performance (number of traffic applications necessary to cause failure). Data for the study were taken from past studies of airfield and highway pavements. A summary of test conditions, failure criteria, and traffic type is given for each data source. A relationship was developed between elastic deflection and the number of coverages of traffic for combined airfield aā€¦ more

Deprivation of Equations Describing Solute Transport in Ground Water

Description: Abstract: A general equation describing the three-dimensional transport and dispersion of a reacting solute in flowing ground water is derived from the principle of conservation of mass. The derivation presented in this report is more detailed but less rigorous than derivations published previously. The general solute-transport equation relates concentration changes to hydrodynamic dispersion, convective transport, fluid sources and sinks, and chemical reactions. Because both dispersion and conā€¦ more
