Beryllium Poisoning Model for Research Reactors

Physics and chemistry of beryllium

The combination of properties of beryllium which results in this very low Z element being a candidate for use in fusion reactors is reviewed. The occurrence, availability, and processing of beryllium from both bertrandite (domestic) and beryl (imported) ores are described. The available beryllium grades are characterized. The purity level of these grades, which are all unalloyed in the usual se...

Chronic beryllium poisoning.

In 1933 Weber and Engelhardt reported the first case of acute pneumonitis due to beryllium poisoning. Other instances of the acute reaction to beryllium salts were described by Van Ordstrand, Hughes, DeNardi, and Carmody (1945). Hardy and Tabershaw (1946) gave details of the chronic or delayed form of the disease, and DeNardi, Van Ordstrand, Curtis, and Zielinski (1953) published a review of 46...

Introduction to the conference on beryllium-related diseases.

This issue of Environmental Health Perspectives Supplements includes papers presented at the Conference on Berylliumrelated Diseases held November 8-10, 1994, at the National Institute of Environmental Health Sciences, Research Triangle Park, North Carolina. Beryllium is the lightest of all solid and chemically stable substances and is used in some form in the aerospace, nuclear, telecommunicat...

Molten-salt Reactors—history, Status, and Potential

Molten-salt breeder reactors (MSBR's) are being developed by the Oak Ridge National Laboratory for generating low-cost power while extending the nation's resources of fissionable fuel. The fluid fuel in these reactors, consisting of UF4 and ThF4 dissolved in fluorides of beryllium and lithium, is circulated through a reactor core moderated by graphite. Technology developments over the past 20 y...
