A study was conducted of the University of California's Lawrence Livermore Laboratory Quality Assurance Program, which focused on training needs and recommendations tailored to the various on-going programs. Specific attention was directed to an assessment of the quality status for the MFTF facility and the capabilities of assigned quality project engineers. Conclusions and recommendations are presented which not only address the purpose of this study, but extend into other areas to provide insight and needs for a total cost effective application of a quality assurance program.

This paper assesses a method for extracting tritium from liquid lithium for specific application to the conceptual laser fusion reactor that uses a continuous lithium ''waterfall.'' The tritium diffuses through a refractory metal that contains a getter and is then stored in a hydride-forming alloy. There are various uncertainties with this method including helium-4 extraction, unknown impurities that may accumulate in liquid lithium, the effects of these impurities on tritium separation, and the maintenance of tritium-contaminated equipment. Our study indicates that major tritium losses will occur during equipment maintenance rather than as a result of permeation losses through the primary vessel.

Progress in developing foil bearings for a miniature isotope-fueled Brayton cycle power system rotating unit (BRU) for space vehicles is reviewed with charts, tables, and diagrams of the program plan and schedule; performance testing; fabrication and inspection; and materials development. (LCL)

Progress in various studies is reported including studies on: vapor phase structures of inorganic salts; solvated electrons; exchange perturbation theory for many-electron interactions; concept of orbital following; calculation of vibrational form factors in electron impact excitation; limiting behavior of molecule-molecule inelastic collision amplitude at zero momentum transfer; partially diffusion-controlled reactions of isolated pair in condensed media; field-dependent mobilities, T-R energy transfer between electronically excited argon and ground-state CO/sub 2/; dose and dose-rate effects in the radiolysis of liquids; coulombically correlated charge-pair distribution and recombination--the role of non-Gaussian diffusion; non-bonded interactions; pulse radiolysis studies of hydrocarbon radical scavenging processes; oxidation of methoxyhydroxycyclohexadienyl radicals by quinones; reaction of hydroxyl radical with phenol; solvent effects on the lifetimes of photogenerated biradicals; oxidation of amines by triplet duroquinone; production of singlet oxygen from excited states of aliphatic ketones; and measurement of electron spin-lattice relaxation times.

The goals of the present program are to develop successful die and container materials for handling liquid silicon while it is being formed into photovoltaic cell material. These goals will hopefully be accomplished by exploring various materials configurations for their reactivity with molten silicon. The combination of unique coating structures combined with control of oxygen partial pressures may yield some previously unsuspected set of conditions which are useful for cost effective die growth or containing silicon melts. Successful experimental configurations will be scaled up into prototype dies and containers as appropriate during the third and fourth quarters of calendar 1978. Economics for large scale production of such prototypes will be defined as part of the program. Die and container material development efforts under the current program are shared among three organizations. Miami Research Laboratories (MRL)--Ceramic process development and overall program management, University of Missouri-Rolla (UMR) (Prof. P.D. Ownby)--silicon sessile drop studies with characterization of reaction products and emphasis on atmospheric effects, Chemetal Corp., Pacoima, Calif. (R. Holzl, president)--special coatings to be applied to test coupons, die shapes and containers provided by MRL and tested/characterized by UMR. MRL has hot pressed three different substrate materials for coating at Chemetal Corp. Chemetal …
