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 …

11 - FFTF-LMFBR seal test program, October-December 1973
The objectives of this program are to: (1) conduct static and dynamic tests to demonstrate or determine the mechanical performance of full-size (cross section) FFTF fuel transfer machine and reactor vessel head seals intended for use in a sodium vapor - inert gas environment, (2) develop and demonstrate these FFTF seals or new seal configurations to provide acceptable fission product and cover gas retention capabilities at LMFBR Demonstration Plant operating environmental conditions other than radiation, and (3) develop improved seals and seal technology for the LMFBR demonstration plants to support the national objective to reduce all atmospheric contaminations to low levels. Reciprocating and rotary dynamic testing of seals generated considerable new test data concerning the leakage, compression set, and wear characteristics of various seal types and materials under specific conditions of compression, temperature, lubrication, travel, and surface finish. Both short-term (information tests) and longer-term (demonstration tests) are being conducted.

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)

241-T-106 tank leak investigation
On June S, 1973, the 241-T-106 underground liquid waste storage tank, located on the U. S. Atomic Energy Commission's Hanford reservation, was confirmed as leaking. It was predicted that the leaked waste would be retained by the dry sediments well above the water table. A study was instigated to confirm this prediction. Results show the deepest penetration observed was 27 meters below the ground surface or 35 meters above the water table (approximately S7 and 116 feet, respectively). Based on these results and the basic knowledge of liquid movement in Hanford sediments, further movement of the radioactivity from its present location will be negligible. (auth)

250-Kg Mirror Coil Development for the Linear Scyllac Experiment
The linear Scyllac theta-pinch machine required mirror coils on each end of the 5-m-long lead coil, which would give mirror ratios of two to three times the 100-kG main coil magnetic field. A pulsed magnetic field of 250 RG was established as a design goal for the mirror coils. Several different designs were evaluated using the 178- kJ, 80-kV Scyllac prototype capacitor bank. Calculations were made to determine the coil geometry for each 250-kG cotl design. A copper-lined, steel-jacketed coil, and an all steel coil were fabricated and tested (4 to 5 cm bores). The types of materials selected for each coli, strength considerations, and fabricating techniques are discussed. The final design of the mirror coils for the 11.2-cm-bore Scyllac machine was established using an all-steel (Maraging type 250) design. An aluminium coil (2014-T652) was built and tested to failure in order to establish data as to the maximum fields that aluminum coils could be subjected to in a typical pulsed theta-pinch evironment. This program and conclusions are discussed. (auth)
