Nuclear Waste Programs Semiannual Progress Report: October 1991-March 1992
This document reports on the work done by the Nuclear Waste Programs of the Chemical Technology Division (CMT), Argonne National Laboratory, in the period October 1991-March 1992. In these programs, studies are underway on the performance of waste glass and spent fuel in projected nuclear repository conditions to provide input to the licensing of the nation's high-level waste repositories.

On the Unsteady-Motion Theory of Magnetic Forces for Maglev
Motion-dependent magnetic forces are the key elements in the study of magnetically levitated vehicle (maglev) system dynamics. In the past, most maglevsystem designs were based on a quasisteady-motion theory of magnetic forces. This report presents an experimental and analytical study that will enhance our understanding of the role of unsteady-motion-dependent magnetic forces and demonstrate an experimental technique that can be used to measure those unsteady magnetic forces directly. The experimental technique provides a useful tool to measure motion-dependent magnetic forces for the prediction and control of maglev systems.

Statistical Guidelines for a Pilot Observer Program to Estimate Turtle Takes in the Hawaii Longline Fishery
Abstract: Statistical guidelines are described for the development of a pilot scientific observer sampling program to collect turtle interactions data from the Hawaii longline fishery. The best available data are presented and potential sources of variability in longline turtle take rates are discussed. A stratified sampling design for a pilot survey is developed based on time and target species. An array of sample size choices for the pilot program is presented covering a range of tolerance levels and confidence levels for estimation of total turtle take.

Using a Transfer Function to Describe the Load-Balancing Problem
The dynamic load-balancing problem for mesh-connected parallel computers can be clearly described by introducing a function that identifies how much work is to be transmitted between neighboring processors. This function is a solution to an elliptic problem for which a wealth of knowledge exists. The non-uniqueness of the solution to the load-balancing problem is made explicit.

Methods for Removing Transuranic Elements from Waste Solutions
This report outlines a treatment scheme for separating and concentrating the transuranic (TRU) elements present in aqueous waste solutions stored at Argonne National Laboratory (ANL). The treatment method selected is carrier precipitation. Potential carriers will be evaluated in future laboratory work, beginning with ferric hydroxide and magnetite. The process will result in a supernatant with alpha activity low enough that it can be treated in the existing evaporator/concentrator at ANL. The separated TRU waste will be packaged for shipment to the Waste Isolation Pilot Plant.

Review and Evaluation of Extractants for Strontium Removal Using Magnetically Assisted Chemical Separation
A literature review on extractants for strontium removal was initially performed at Northern Illinois University to assess their potential in magnetically assisted chemical separation. A series of potential strontium extractants was systematically evaluated there using radioanalytical methods. Initial experiments were designed to test the uptake of strontium from nitric acid using several samples of magnetic extractant particles that were coated with various crown ether ligands. High partition coefficient (K(sub d)) values for stimulant tank waste were obtained. Further studies demonstrated that the large partitioning was due to uncoated particles.

A Review of Dynamic Characteristics of Magnetically Levitated Vehicle Systems
The dynamic response of magnetically levitated (maglev) ground transportation systems has important consequences for safety and ride quality, guideway design, and system costs. Ride quality is determined by vehicle response and by environmental factors such as humidity and noise. The dynamic response of the vehicles is the key element in determining ride quality, while vehicle stability is an important safety-related element. To design a guideway that provides acceptable ride quality in the stable region, vehicle dynamics must be understood. Furthermore, the trade-off between guideway smoothness and levitation and control systems must be considered if maglev systems are to be economically feasible. The link between the guideway and the other maglev components is vehicle dynamics. For a commercial maglev system, vehicle dynamics must be analyzed and tested in detail. This report, which reviews various aspects of the dynamic characteristics, experiments and analysis, and design guidelines for maglev systems, discusses vehicle stability, motion dependent magnetic force components, guideway characteristics, vehicle/ guideway interaction, ride quality, suspension control laws, aerodynamic loads and other excitations, and research needs.

Commonwealth of the Northern Mariana Islands as a Fishing Community
From introduction and purpose: This report describes the Commonwealth of the Northern Mariana Islands (CNMI) as a fishing community. We have tried to strike a balance between the report being concise enough to be useful while covering the full range of topics and issues necessary to describe CNMI as a fishing community...This report will be updated periodically as social, economic, and environmental conditions change and fishermen and fisheries management adapt to those changes.
