Critical Review of Glass Performance Modeling

Description: Borosilicate glass is to be used for permanent disposal of high-level nuclear waste in a geologic repository. Mechanistic chemical models are used to predict the rate at which radionuclides will be released from the glass under repository conditions. The most successful and useful of these models link reaction path geochemical modeling programs with a glass dissolution rate law that is consistent with transition state theory. These models have been used to simulate several types of short-term l… more

Aerovalve Pulse Combustion: Technical Note

Description: The authors present a mathematical model and an experimental investigation of aerodynamically valved pulse combustion. The model uses a control-volume approach to solve conservation laws in several regions of a pulse combustor. Mixing between the fresh charge and combustion products is modeled as a two-step process, with the mixing occurring slowly for a specified eddy time during each cycle, and then changing to a higher rate. Results of model simulations demonstrate that eddy time plays a sig… more

Measurement of thermal regain in duct systems located in partially conditioned buffer spaces. Informal report

Description: Thermal losses from duct systems have been shown to be a significant fraction of the heat or cooling energy delivered by the space-conditioning equipment. However, when the ducts are located in a partially conditioned buffer space such as a basement, a portion of these losses are effectively regained through system interactions with the building. This paper presents two methods of measuring this regain effect. One is based on the relative thermal resistances between the conditioned space and th… more

Kokanee Stock Status and Contribution of Cabinet Gorge Hatchery, Lake Pend Oreille, Idaho, Final Report.

Description: Lake Pend Oreille once provided the most popular kokanee Oncorhynchus nerka fishery in northern Idaho. A dramatic decline in the population occurred from the mid-1960s to 1970s. Restoration efforts included construction of the Cabinet Gorge Fish Hatchery to supplement the wild population and restore the fishery. In this study, hatchery-reared age 0 kokanee were stocked into Lake Pend Oreille from 1986 through 1992. Seven experimental stocking strategies for kokanee were tested using five locati… more

Development of hydrogeological modelling approaches for assessment of consequences of hazardous accidents at nuclear power plants

Description: This paper introduces some modeling approaches for predicting the influence of hazardous accidents at nuclear reactors on groundwater quality. Possible pathways for radioactive releases from nuclear power plants were considered to conceptualize boundary conditions for solving the subsurface radionuclides transport problems. Some approaches to incorporate physical-and-chemical interactions into transport simulators have been developed. The hydrogeological forecasts were based on numerical and se… more

RHIC warm-bore systems

Description: Pressure profiles, in time, are calculated as a consequence of anticipated outgassing of various beam components (e.g., rf cavities, etc.) and warm-bore beam pipes. Gold beam lifetimes and transverse beam emittance growth are given for calculated average pressures. Examples of undesirable warm-bore conditions are presented such as contaminated experimental beam pipes and warm-bore magnets (i.e., DX). These examples may prove instructive. The methods used in making these calculations are present… more

Ferruginous hawks on the Yakima Training Center

Description: Habitat quality for ferruginous hawks (Buteo regalis) is largely determined by availability of nest sites and adequate prey base. A limitation of one of these will limit the number of hawks in an area. In general, ferruginous hawks are adaptable to various nesting substrates and will nest in proximity to other closely related sympatric species (e.g., red-tailed hawk, Swainson`s hawk). This analysis focused on an assessment of prey base availability and habitat disturbance in the vicinity of his… more
