2$sup 0$K vacuum pumping system for Baseball II (open access)

2$sup 0$K vacuum pumping system for Baseball II

A vacuum pumping system that provides a cryo surface for condensing and freezing of H/sub 2/ gas is described. A closed-loop vacuum system was designed and built at Lawrence Livermore Laboratory to pump down the neutralizer LH/sub e/ dewar with a volurae of 350 l and the lambda point dewar with a LH/sub e/ volume of 250 l. Both of these dewars can be pumped down simultaneously or one at a time. 100% of the H/sub e/ gas is recovered free of contaminations. The vacuum pump can handle 340 SCFM of gas. The LH/sub e/ dewars are pumped down below the lambda point. This condition reduces the LH/sub e/ container wall temperature to 2.1 deg K giving a base pressure of 10/sup -13/ torr for H/sub 2/ gas/sup 2/. To attain a stable condition the LH /sub e/ baths are puuped down to 33 torr or lower to give a surface temperatare of about 2/sup 0/K/sup 3/. The Baseball II helium factlity is a close loop system. The H/sub e/ gas is recovered from all the LH/sub e/ usage point. This gas is accumulated in one of the two 8000 cu ft inflatable gas bags. The gas from the gas …

9/11 Commission Recommendations: Joint Committee on Atomic Energy - A Model for Congressional Oversight? (open access)

9/11 Commission Recommendations: Joint Committee on Atomic Energy - A Model for Congressional Oversight?

This report focuses on that portion of the 9/11 Commission recommendation that urges Congress to consider the model of the Joint Committee on Atomic Energy (JCAE). It provides an outline of the history, structure, and powers of the JCAE and analyzes a number of issues that might be considered by policymakers as they weigh the suitability of the JCAE as a possible model when crafting congressional oversight mechanisms for intelligence.

100-D Area technical baseline report (open access)

100-D Area technical baseline report

This document is prepared in support of the 100 Area Environmental Restoration activity at the US Department of Energy`s Hanford Site near Richland, Washington. It provides a technical baseline of waste sites located at the 100-D Area. The report is based on an environmental investigation undertaken by the Westinghouse Hanford Company (WHC) History Office in support of the Environmental Restoration Engineering Function and on review and evaluation of numerous Hanford Site current and historical reports, drawings, and photographs, supplemented by site inspections and employee interviews. No intrusive field investigation or sampling was conducted. All Hanford coordinate locations are approximate locations taken from several different maps and drawings of the 100-D Area. Every effort was made to derive coordinate locations for the center of each facility or waste site, except where noted, using standard measuring devices. Units of measure are shown as they appear in reference documents. The 100-D Area is made up of three operable units: 100-DR-1, 100-DR-2, and 100-DR-3. All three are addressed in this report. These operable units include liquid and solid waste disposal sites in the vicinity of, and related to, the 100-D and 100-DR Reactors. A fourth operable unit, 100-HR-3, is concerned with groundwater and is …

200 amp Neutral Beam Source (open access)

200 amp Neutral Beam Source

Recent efforts in controlled fusion experiments have indicated the need for large neutral-beam sources to provide an initial plasma for further plasma buildup, for use as a stoking source to makeup losses, or for plasma heating. Experiments now operating or envisioned for the near future anticipate the need for kilo-amp neutral beams in the 20-keV energy range and higher. These sources will be required to focus into relatively small-volume targets, have good gas efficiency, and use a minimum of excess gas for downstream neutralization. A test facility with sufficient pumping capacity to handle sources of this size is described. The ion source, mockup extraction grid, and the requisite electronic and power equipment for a 200-amp neutral-deuterium beam are discussed. The beam pulse length will be from 2 to 10 msec. (auth)

709 Program for Reduction of Exponential Pile Data (open access)

709 Program for Reduction of Exponential Pile Data

A multi-purpose program for processing exponential data has been prepared for the 709 computer. The main purposes of the program is to compute the material buckling from raw data (given counts, time, and counter information) or from previously calculated Athermal's. It is also possible to compute only CeCh (end and harmonic corrections) for a given B11 or series if B11's no counting data being entered. In every case, pile measurements must be submitted as input for corrections.
