DIF3D: A Code to Solve One-, Two-, and Three-Dimensional Finite-Difference Diffusion Theory Problems
The mathematical development and numerical solution of the finite-difference equations are summarized. The report provides a guide for user application and details the programming structure of DIF3D. Guidelines are included for implementing the DIF3D export package on several large scale computers. Optimized iteration methods for the solution of large-scale fast-reactor finite-difference diffusion theory calculations are presented, along with their theoretical basis. The computational and data management considerations that went into their formulation are discussed. The methods utilized include a variant of the Chebyshev acceleration technique applied to the outer fission source iterations and an optimized block successive over-relaxation method for the within-group iterations. A nodal solution option intended for analysis of LMFBR designs in two- and three-dimensional hexagonal geometries is incorporated in the DIF3D package and is documented in a companion report, ANL-83-1.

Atmospheric Corrosion of batten and Enclosure Materials for Flat-Plate Solar Collectors
As part of the Solar Reliability and Materials Program at Argonne National Laboratory, the atmospheric corrosion of candidate batten and enclosure materials were tested on outdoor racks parallel to the tilted solar-collected panels at nine National Solar Data Network (NSDN) sites, located in mild marine, mild industrial, and rural environments. The candidate materials evaluated include galvanized steel (G-90), aluminized steel (Type 2), aluminum (6061), and white polyester painted steel. Data analyses predicted that all the first three materials will last more than 20 years in the nine sites tested. However, repainting of the painted steel is probably needed within five years in a mild marine environment and five to ten years in a mild industrial or rural environment.

Metal Corrosion Associated with Thermal Cycling of Inhibited and Uninhibited Propylene Glycol/Water Solution in Solar DHW Systems
As part of the Solar Reliability and Materials Program at Argonne National Laboratory, metal corrosion associated with thermal cycling at 82 C circulating and 176 C stagnating temperatures of propylene glycol and ASTM corrosive water mixture (50% v/o) was investigated. Preliminary data indicate that in a mixed metal system of copper, steel, and aluminum specimens stagnating together in a glycol solution, the copper randomly pits and the pitting stops when the pit depth extends to about 1-1/2 mil. The addition of 1% molybdate as an inhibitor to the glycol solution is slightly beneficial for steel, but the added expense of adding and maintaining the concentration of an inhibitor may not be warranted. Dissolved copper rapidly deposits on the aluminum surface and promotes severe galvanic corrosion.

TCLUST1: A Computer Program for Analysis of Intersubassembly Heat Transfer in an LMFBR
The TCLUST1 computer program was developed to study the transient thermal behavior of a subassembly of a liquid-metal fast breeder reactor (LMFBR) that is thermally coupled to its six neighboring subassemblies. Each of the seven subassemblies may be either a reflector subassembly, which contains a single solid hexagonal rod, or a pin-bundle subassembly. The TCLUST1 analytical model was developed based on conservation of energy, and the temperature distribution in the subassembly was obtained using the successive over-relaxation (SOR) technique. Measured temperatures obtained from a natural-convection flow test performed in EBR-II compare well with those predicted by TCLUST1. Appendixes describe the code input and go through a sample program.

Laboratory Testing of Glasses for Lockheed Idaho Technology Co. Fiscal Year 1994 Report
The purpose of this project is to measure the intermediate and long-term durability of vitrified waste forms developed by Lockheed Idaho Technology Co. (LITCO) for the immobilization of calcined radioactive wastes at Idaho National Engineering Laboratory. Two vitreous materials referred to as Formula 127 and Formula 532, have been subjected to accelerated durability tests to measure their long-term performance. Formula 127 consists of a glass matrix containing 5-10 vol % fluorite (CaF2) as a primary crystalline phase. It shows low releases of glass components to solution in 7-, 28-, 70-, and 140-day Product Consistency Tests performed at 2000 m⁻¹ at 90 C. In these tests, release rates for glass-forming components were similar to those found for durable waste glasses. The Ca and F released by the glass as it corrodes appear to re-precipitate as fluorite. Formula 532 consists of a glass matrix containing 5-10 vol % of an Al-Si-rich primary crystalline phase. The release rates for components other than aluminum are relatively low, but aluminum is released at a much higher rate than is typical for durable waste glasses. Secondary crystalline phases form relatively early during the corrosion of Formula 532 and appear to consist almost entirely of the Al-Si-rich …

Surveillance of Site A and Plot M : Report for 1989
The results of the environmental monitoring program conducted at Site A/Plot M in the Palos Park Forest Preserve area for CY 1989 are presented. The monitoring program is the ongoing remedial action that resulted from the 1976-1978 radiological characterization of the site. That study had determined that very low levels of hydrogen-3 (as tritiated water) migrated from the burial ground and was present in two nearby hand-pumped picnic wells. The current program consists of sample collection and analysis of air, surface and subsurface water, and bottom sediment.

Fluidized-Bed Regeneration of Sulfated Dolomite from a Coal-Fired FBC Process by Reductive Decomposition
A fluidized-bed, reductive decomposition process has been developed for regenerating calcium sulfate, a product of fluidized-bed combustion. The effect of process operating variables on the extent of regeneration and on the SO2 levels in the off-gas has been determined, and a process model has been proposed. A process for regenerating spent SO2 sorbents has been developed on a PDU scale. Tymochtee dolomite that had been sulfated during fluidized-bed combustion of coal is regenerated (reductive decomposition of calcium sulfate to calcium oxide and SO2) by the incomplete combustion of either methane or coal in a fluidized-bed reactor.

Engineering Analysis of Thermal Phenomena for Lead-Acid Batteries During Recharge Processes
Transient thermal phenomena in Pb/PbO2 (lead-acid) batteries during charging processes were investigated. Mathematical models were formulated for the studies of heat transfer behavior across the electrode/electrolyte interface within a porous PbO2 electrode during charging, thermal behavior and temperature distribution over a lead-acid battery during different charging processes designed for electric-vehicle propulsion application, and cooling methods for lead-acid batteries during recharge cycles. Numerical solutions show that the heat transfer across the solid electrode and the electrolyte within the porous electrode is so fast that their temperatures may be regarded as the same. The results also show that, in a lead-acid battery designed for electric-vehicle propulsion, the heat generated in the cell during fast charging processes may cause a noticeable rise of temperature in the cell if the heat is not removed properly. The studies of heat-removal processes indicate that incorporation of cooling tubes within the cell cannot effectively remove the heat being released from the cell. However, the heat may be removed effectively by circulation of electrolyte through the battery. Numerical solutions are provided for the engineering evaluation of heat-removal design during battery cycling processes.

Some Issues Concerning Fluidelastic Instability of a Group of Circular Cylinders in Crossflow
Since the early 1970s, extensive studies of fluid-elastic instability of circular cylinders in crossflow have been reported. A significant understanding of the phenomena involved now exists. However, some confusion, misunderstanding, and misinterpretation still remain. The objective of this report is to discuss, on the basis of the current state of the art, a series of the most asked questions. Emphasis is placed on the determination of the critical flow velocity, non-dimensional parameters, stability criteria, and instability mechanisms.

Dynamic Stability of Maglev Systems
Because dynamic instability is not acceptable for any commercial maglev systems, it is important to consider this phenomenon in the development of all maglev systems. This study considers the stability of maglev systems based on experimental data, scoping calculations, and simple mathematical models. Divergence and flutter are obtained for coupled vibration of a three-degree-of-freedom maglev vehicle on a guideway consisting of double L-shaped aluminum segments attached to a rotating wheel. The theory and analysis developed in this study identifies basic stability characteristics and future research needs of maglev systems.

Dynamic Stability Experiment of Maglev Systems
This report summarizes the research performed on Maglev vehicle dynamic stability at Argonne National Laboratory during the past few years. It also documents magnetic-force data obtained from both measurements and calculations. Because dynamic instability is not acceptable for any commercial Maglev system, it is important to consider this phenomenon in the development of all Maglev systems. This report presents dynamic stability experiments on Maglev systems and compares their numerical simulation with predictions calculated by a nonlinear dynamic computer code. Instabilities of an electrodynamic system (EDS)-type vehicle model were obtained from both experimental observations and computer simulations for a five-degree-of-freedom Maglev vehicle moving on a guideway consisting of double L-shaped aluminum segments attached to a rotating wheel. The experimental and theoretical analyses developed in this study identify basic stability characteristics and future research needs of Maglev systems.

The Effect of Pressure on the Transient Swelling Rate of Oxide Fuel
An analysis of the transient swelling rate of oxide fuel, based on fission-gas bubble conditions calculated with the FRAS3 code, has been developed and implemented in the code. The need for this capability arises in the coupling of the FRAS3 fission-gas analysis code to the FPIN fuel-pin mechanics code. An efficient means of closely coupling the calculations of swelling strains and stresses between the modules is required. The present analysis provides parameters that allow the FPIN calculation to proceed through a fairly large time step, using estimated swelling rates, to calculate the stresses. These stress values can then be applied in the FRAS3 detailed calculation to refine the swelling calculation, and to provide new values for the parameters to estimate the swelling in the next time step. The swelling rates were calculated for two representative transients and used to estimate swelling over a short time period for various stress levels.

HYCSOS : A Chemical Heat Pump and Energy Conversion System Based on Metal Hydrides
The current status of the HYCSOS chemical heat pump and energy conversion system based on metal hydrides is described. Heat transfer fluid loops were insulated and modified for isothermal operation. Software development for HYCSOS manual mode operation was completed. Routines to handle data acquisition, logging, compression, correction and plotting, using a Tektronix Graphics system with flexible disk data storage, provide a rapid and versatile means of presenting HYCSOS data for analysis. Advanced concept heat exchangers to improve the heat transfer of the hydride bed with the heat transfer fluid are discussed. Preliminary tests made with a LaNi5 loaded aluminum foam test unit showed that heat transfer properties are very markedly improved. Thermodynamic expressions are applied to the selection of alloys for use in HYCSOS. The substitution of aluminum for nickel in AB5 type alloys is shown to reduce hysteresis and permits the use of potentially lower cost materials with added flexibility for the optimization of engineering design and performance characteristics of the hydride heat pump system. Transient thermal measurements on hydride beds of CaNi5 and LaNi5 show no deterioration with cycling. Relatively slow heat transfer between the hydride beds and heat transfer fluid in the coiled tube heat exchangers is …
