SYN3D: a Single-Channel, Spatial Flux Synthesis Code for Diffusion Theory Calculations

SYN3D: a Single-Channel, Spatial Flux Synthesis Code for Diffusion Theory Calculations

Date: 1976
Creator: Adams, C. H.
Description: This report is a user's manual for SYN3D, a computer code which uses single-channel, spatial flux synthesis to calculate approximate solutions to two- and three-dimensional, finite-difference, multi-group neutron diffusion theory equations. SYN3D is designed to run in conjunction with any one of several one- and two-dimensional, finite-difference codes (required to generate the synthesis expansion functions) currently being used in the fast reactor community. The report describes the theory and equations, the use of the code, and the implementation on the IBM 370/195 and CDC 7600 of the version of SYN3D available through the Argonne Code Center.

Numerical Integration of Large Deflection Elastic-Plastic Axisymmetric Shells of Revolution

Numerical Integration of Large Deflection Elastic-Plastic Axisymmetric Shells of Revolution

Date: December 1976
Creator: Ahmed, Habib Uddin
Description: The improvement in the method of large deflection elastic-plastic analysis of shells and other structures appears to have continued interest. With the development in this work an improved numerical suppression scheme is now available for the large deflection elastic-plastic analysis of axisymmetric shells of revolution subjected to symmetric loadings. Quasi-linearization of Sander's non-linear shell equations is presented for the first time. With these quasi-linearized equations the suppression scheme has been developed to solve non-linear boundary-value problems. This suppression scheme has been used in conjunction with a Newton-Raphson method to improve a stable convergence process at the yield surface in elastic-plastic problems. Results presented indicate the accuracy of this numerical scheme. It appears to be possible to extend this method for more complicated situations.

An Overview of Pool-Type LMFBRs : General Characteristics

An Overview of Pool-Type LMFBRs : General Characteristics

Date: May 1976
Creator: Amorosi, A.; Hutter, E.; Marciniak, T. J.; Monson, H. O.; Seidensticker, R. W. & Simmons, W. R.
Description: This report describes the results of a study conducted by a "Pool Study Group" organized at ANL in mid-1975 to examine the present state of the air of design of pool-type LMFBRs. The study concentrated on examination of various design options used to date in the principle pool-type projects and design studies in this country and abroad, including the Phenix and Super-Phenix reactors (France), PFR and CFR (U.K.), RN-600 (U.S.S.R.) and EBR-II (U.S.A.). The objective of the report is to provide a step toward better understanding of the pool-type system and of the advantages and disadvantages of the various possible approaches to its design.

Final Report on the Small-Scale Vapor-Explosion Experiments Using a Molten NaCl-H2O System

Final Report on the Small-Scale Vapor-Explosion Experiments Using a Molten NaCl-H2O System

Date: April 1976
Creator: Anderson, R. P. & Bova, L.
Description: Vapor explosions were produced by injecting small quantities of water into a container filled with molten sodium chloride. Minimum explosion efficiencies, as evaluated from reaction-impulse measurements, were relatively large. Subsurface movies showed that the explosions resulted from a two-step sequence: an initial bulk-mixing phase in which the two liquids intermix on a large scale, but remain locally separated by an insulating gas-vapor layer; and a second step, immediately following breakdown of the gas layer, during which the two liquids locally fragment, intermix, and pressurize very rapidly. The experimental results were compared with various mechanistic models that had been proposed to explain vapor explosions. Early models seemed inconsistent with the results. More recent theories suggest that vapor explosions may be caused by a nucleation limit or by dynamic mixing combined with high surface-heat-transfer rates. Both types of models are consistent with the results.

Environmental Pollutants and the Urban Economy : Phase 1. Final Report, June 1972-October 1975

Environmental Pollutants and the Urban Economy : Phase 1. Final Report, June 1972-October 1975

Date: October 1976
Creator: Argonne National Laboratory
Description: Costs and benefits of various urban air pollution control policies have been examined in Phase 1 of the Environmental Pollutants and the Urban Economy study being conducted jointly by Argonne National Laboratory and the University of Chicago. The need for sound economic evaluation of air quality regulations is evidenced by the resistance of many industries to pollution control policies based solely on the technical feasibility of achieving public health-related standards. For many firms that emit air pollutants, the cost of not complying with some regulations is significantly less than the cost of compliance. This final report on the Phase 1 research presents highlights of what has been learned, the mechanisms developed for transferring results to users, a bibliography of documents produced during the project, and a collection of correspondence, articles, and evaluation illuminating the use of project work by others.
