Analysis of Homogeneous Charge Compression Ignition (HCCI) Engines for Cogeneration Applications

Description: This paper presents an evaluation of the applicability of Homogeneous Charge Compression Ignition Engines (HCCI) for small-scale cogeneration (less than 1 MWe) in comparison to five previously analyzed prime movers. The five comparator prime movers include stoichiometric spark-ignited (SI) engines, lean burn SI engines, diesel engines, microturbines and fuel cells. The investigated option, HCCI engines, is a relatively new type of engine that has some fundamental differences with respect to oth… more

Bio-hydrogen production from renewable organic wastes

Description: Methane fermentation has been in practice over a century for the stabilization of high strength organic waste/wastewater. Although methanogenesis is a well established process and methane--the end-product of methanogenesis is a useful energy source; it is a low value end product with relatively less energy content (about 56 kJ energy/g CH{sub 4}). Besides, methane and its combustion by-product are powerful greenhouse gases, and responsible for global climate change. So there is a pressing need … more

Bounds on Elastic Constants for Random Polycrystals of Laminates

Description: A well-known result due to Hill provides an exact expression for the bulk modulus of any multicomponent elastic composite whenever the constituents are isotropic and the shear modulus is uniform throughout. Although no precise analog of Hill's result is available for the opposite case of uniform bulk modulus and varying shear modulus, it is shown here that some similar statements can be made for shear behavior of random polycrystals composed of laminates of isotropic materials. In particular, t… more

Cavity Like Completions in Weak Sands Preferred Upstream Management Practices: FInal Technical Report

Description: The technology referred to as Cavity Like Completions (CLC) offers a new technique to complete wells in friable and unconsolidated sands. A successfully designed CLC provides significant increases in well PI (performance index) at lower costs than alternative completion techniques. CLC technology is being developed and documented by a partnership of major oil and gas companies through a GPRI (Global Petroleum Research Institute) joint venture. Through the DOE-funded PUMP program, the experience… more

Characterization of Uranium in Archived 2H Evaporator Scale

Description: This research was conducted to improve our fundamental understanding of the mechanisms of U accumulation with NAS in the evaporators and in other process areas at the SRS that may concentrate U in the presence of silicates, aluminum and NAS. Our study uses information gained from the characterization of solids formed in laboratory tests under similar HLW evaporator conditions to aid our interpretation of characterization data of an actual archived 2H Evaporator scale sample. These basic scienti… more

Chemical Oxygen Demand (COD) For Monitoring Reduction-Oxidation (Redox) Equilibrium During High Level Waste (HLW) Vitrification

Description: High-level nuclear waste is being immobilized at the Savannah River Site by vitrification into borosilicate glass at the Defense Waste Processing Facility. Control of the REDuction/OXidation (REDOX) equilibrium in the DWPF melter is critical for processing high level liquid wastes. Based upon previous research, an acceptable iron REDOX ratio was defined for the DWPF melts as 0.09 Fe2/SFe 0.33. Controlling the DWPF melter at a REDuction/OXidation (REDOX) equilibrium ofFe2/SFe 0.33 prevents the p… more

Conditions Conducive to Forming Crystalline Uranyl Silicates in SRS Evaporators

Description: The laboratory conditions under which synthetic uranyl silicates are made are almost identical to SRS evaporator conditions,with the exception of differences in sodium ion concentration. Synthetic uranyl silicates have been made only under low sodium ion concentration (less than 0.02 M), while attempts to synthesize uranyl silicates in this study in the presence of high sodium ion concentration (5.6 M), which are typical of SRS evaporators have proved unfruitful. In the presence of soluble sili… more

Developing First-Principles Reactive Force Fields and Densification Process for Y-Doped BaZrO3 Proton-Conducting Ceramics

Description: During the third semi-annual period we have mostly finished a series of QM calculations on relevant metals (Pt, Zr, Y, Ba), metal alloys (Y/Zr), metal oxides (ZrO{sub 2}, Y{sub 2}O{sub 3}, BaO) and Y-doped BaZrO{sub 3}. Based on these data we started developing ReaxFF for further MD simulations of different physico-chemical processes in the electrolyte and at the electrode/electrolyte interface. To accelerate the densification process of BaZrO{sub 3} ceramics at lower temperature an initial scr… more

Drop Tests for the 6M Specification Package Closure Investigation

Description: Results of tests of drum-type RAM packages employing conventional clamp-ring closures have caused concern over the DOT 6M Specification Package. To clarify these issues, a series of tests were performed to determine the response of the clamp-ring closure to the regulatory Hypothetical Accident Condition (9m) drop tests, for packages at maximum allowable weight. Three enhanced closure designs were also tested: the Clamshell, plywood disk reinforcement, and J-Clip. The results of the tests showed… more

Drop Tests of 325 Pound 6M Specification Packages

Description: Testing of 6M specification packages, performed in response to concerns over the integrity of the clamp-ring closure, showed that the clamp-ring was unable to retain the top in thirty foot drop tests of packages having the maximum allowed weight (290 kg or 640 lb). To determine if the clamp-ring closure was adequate for packages with lower contents weight, a series of tests were performed on packages weighing 147 kg (325 lb) at a range of impact angles. The results showed that the standard clam… more

Effects of Ammonium Molybdophosphate (AMP) on Strontium, Actinides, and RCRA Metals in SRS Simulated Waste

Description: High Level Waste samples contain elevated concentrations of radioactive cesium requiring marked dilution of the waste to facilitate handling in non-shielded facilities. The authors developed a sample treatment protocol, using ammonium molybdophosphate (AMP) to remove sufficient cesium to allow handling of the samples with minimal dilution. The sample treatment protocol includes the following steps: pH adjust the sample to the range of 0.01 to 1.0 M acidity; mix 30 mL of acidified sample with 40… more

Effects of Initial Conditions on Compressible Mixing in Supernova-Relevant Laboratory Experiments

Description: In core-collapse supernovae, strong blast waves drive interfaces susceptible to Rayleigh-Taylor (RT), Richtmyer-Meshkov (RM), and Kelvin-Helmholtz (KH) instabilities. In addition, perturbation growth can result from material expansion in large-scale velocity gradients behind the shock front. Laser-driven experiments are designed to produce a strongly shocked interface whose evolution is a scaled version of the unstable hydrogen-helium interface in core-collapse supernovae such as SN 1987A.

Electrochemical Tests of Carbon Steel in Simulated Waste Containing Fenton's Reagent

Description: Preliminary tests have been completed to assess the corrosivity of an in-tank process to decompose cesium and potassium tetraphenylborate in Tank 48H. Testing was requested by the Tank 48 Closure Team to ''Perform a corrosion study to assess the effects of reduced pH solution on Tank 48 components''. The initial corrosion tests were in support of the Fenton's reagent process with ferric ion. A second set of tests was performed with tetraamido macrocylcic ligand in place of ferric ion.
