The Air-Launched Balloon System (ALBS) Development Program, Phase 2

Description: Abstract: The circumstances leading to the second phase of the Air-Launched Balloon System Development Program are described, along with the governing design constraints. Individual component development efforts and system design modifications are described in turn: the procurement and testing of the new dewar, the qualification of the updated cryogenic unit recovery system. The complicated command, control, and telemetry subsystem is also described in detail. The results of component tests and… more

Analysis of the October 5, 1979 Lithium Spill and Fire in the Lithium Processing Test Loop

Description: On October 5, 1979, the Lithium Processing Test Loop (LPTL) developed a lithium leak in the electromagnetic (EM) pump channel, which damaged the pump, its surrounding support structure, and the underlying floor pan. A thorough analysis of the causes and consequences of the pump failure was conducted by personnel from CEN and several other ANL divisions. Metallurgical analyses of the elliptical pump channel and adjacent piping revealed that there was a significant buildup of iron-rich crystallit… more

Computing a Trust Region Step

Description: An algorithm is proposed for the problem of minimizing a quadratic function subject to an ellipsoidal constraint which is guaranteed to produce a nearly optimal solution in a finite number of iterations. A robust and efficient algorithm for this problem is required to compute the step between iterates in trust region methods for optimization problems. We also consider the use of our algorithm in a trust region Newton's method. In particular, we prove that under reasonable assumptions the sequen… more

Dispersive Approximations for Hyperbolic Conservation Laws

Description: Necessary and sufficient conditions are given so that the Sobolev-type partial differential equations generate a contraction semigroup. It is shown that any nonlinear contraction from L/sup 1/(R) to itself that preserves the integral and commutes with translations satisfies maximum and minimum principles. This lemma is applied to the solution operator S/sub t/ to give necessary and sufficient conditions that S/t/ satisfy a maximum principle, despite the dispersive nature. Sufficient conditions … more

Hydrologic Characteristics and Possible Effects of Surface Mining in the Northwestern Part of West Branch Antelope Creek Basin, Mercer County, North Dakota

Description: From introduction: The specific objectives of the study were to: (1) Determine the premining hydrologic and geochemical conditions in the 28 mi2 area; (2) provide a premining data base from which to measure the magnitude of change in the hydrologic system due to coal mining; and (3) determine the probable effects of mining on the water resources in the area.

National Uranium Resource Evaluation: Tularosa Quadrangle, New Mexico

Description: From Purpose and Scope: "The Tularosa Quadrangle (2º), New Mexico (Fig. 1), was evaluated to identify geologic units and delineate specific areas that have characteristics favorable for occurrence of uranium deposits. All geologic environments to a depth of 1500 m were evaluated by means of surface investigations and examination of geophysical well logs."

Extensions of DISPL TO R-[theta] Geometry

Description: DISPL is a software package for solving systems of nonlinear partial differential equations of initial value type over a two-dimensional spatial domain. This report described an extension of the approximation procedure to include spatial domains described by polar geometry. More generally the extension includes problems for which there is periodicity in one of the spatial directions.

The MAP3S Aerosol Sulfate Acidity Network: A Progress Report and Data Summary, November 1981

Description: Abstract: A network of five atmospheric aerosol samplers was established in the northeastern US starting in February 1977. Size-fractionated samples of the aerosol were collected continuously with four-hour time resolution until the network was dismantled in February 1980. The aerosol-loading and aerosol-chemistry data obtained over this three-year period are summarized in this report. In particular, the samples were analyzed for the sulfate acidity of the aerosol. The acidity was found to be q… more

Nuclear Material Safeguards Surveillance and Accountancy by Isotope Correlation Techniques

Description: The purpose of this study is to investigate the applicability of isotope correlation techniques (ICT) to the Light Water Reactor (LWR) and the Liquid Metal Fast Breeder Reactor (LMFBR) fuel cycles for nuclear material accountancy and safeguards surveillance. The isotopic measurement of the inventory input to the reprocessing phase of the fuel cycle is the primary direct determination that an anomaly may exist in the fuel management of nuclear material. The nuclear materials accountancy gap whic… more
