A unique high-efficiency particulate air (HEPA) filter medium has been developed for applications in high temperature and high pressure environments. This filter medium is a composite made from quartz and stainless-steel fibers that have been sintered together. The composite medium has the same efficiency and pressure drop as standard HEPA glass media, but has four times the tensile strength and can operate continuously at temperatures up to 500/degree/C. In a conventional HEPA, the binder burns out above 250/degree/C and the medium loses its strength; our composite filter medium has no comparable loss of strength even at 500/degree/C. 8 refs., 8 figs., 1 tab.

The original CMX hydraulic data for the Mark 22 assembly, obtained by L.W. Ridenhour in 1972, is analyzed and documented. Comparisons are made to Ridenhour's working notebooks and summary document, and to the Mark 22 hydraulics manual. Several errors in these documents are corrected. Correlations are given in a form suitable for revisions to the hydraulics manual. The experimental setup and measurements are briefly described, and the original data is compiled in the appendix to this report. An error in the recorded length between channel pressure taps was found in Ridenhour's notebook. This error impacts the channel pressure drop correlations obtained by Ridenhour and used in the hydraulics manual. The hydraulics of the two purge channels are analyzed based on the geometry of the orifices and on the limited data available. The limited data is shown to be in reasonable agreement with accepted orifice correlations. Purge channel correlations are given, and the purge channel flow splits are shown to be about 1.5% of the total flow.

The design of future Engineering Test Reactor (ETR) to demonstrate ignition is complicated by the uncertainties in the projected database for ignited plasmas. Application of uncertainty analysis to ETR design utilizing a figure-of-merit defined as the probability of ignition is presented. Performance evaluation from the uncertainty analysis in density-temperature space can locate an optimum operating window for ignition. 11 refs., 5 figs., 3 tabs.

This paper presents a recently modified verion of the 2-D DART code designed to simulate the behavior of a beam of charged particles whose paths are affected by electric and magnetic fields. This code was originally used to design laboratory-scale and full-scale beam direct converters. Since then, its utility has been expanded to allow more general applications. The simulation technique includes space charge, secondary electron effects, and neutral gas ionization. Calculations of electrode placement and energy conversion efficiency are described. Basic operation procedures are given including sample input files and output. 7 refs., 18 figs.
