Research programs requiring quality assurance surveillance, certification procedures, and associated record keeping have increased markedly at the Los Alamos Scientific Laboratory. A computer-based system, accessible through time-sharing terminals, performs many routine operations, including continued records updating for equipment calibration, personnel certification, quality assurance procedure listings, and controlled-document distribution lists. The system described has operated successfully for more than a year, resulting in a significant savings in man-hours required to keep quality assurance records.

In more than 17 years of studying underground nuclear explosions, LLL has developed containment procedures that include a stemming plan. Stemming plans can be divided into either layered or continuous forms. There are marked differences between standards for these forms. The materials used in the continuous plan must meet more stringent specifications; as a consequence, they are more expensive. Both plans have been successful since the Baneberry Event. Both plans must meet the following requirements: provide a plug sufficient to match the overburden density of earth; contain radioactive gases at the lowest possible depth; minimize the generation of noncondensable gases (such as CO/sub 2/); minimize gas flow rates during the early post-detonation stages when cavity pressure is high; and be compatible with the experiment and its diagnostics. LLL experience in developing containment procedures is reviewed, and the reasons for the adoption of LLL's continuous stemming plan are reported. (LCL)

Data are presented from a preliminary analysis of chemical/physical data obtained during three current meter servicing cruises in Onslow Bay off the coast of Georgia, in August, October, and December 1975 aboard the R/V ADVANCE II. These cruises were made as part of an ERDA sponsored study investigating the shelf processes effecting the distribution of nutrients in the South Atlantic Bight. The objective of these cruises was to collect temperature and chemical data to correlate with the data recorded by current meters and thermographs which had already been deployed or which were about to be deployed at two locations in the study area. No attempt will be made at this time however to correlate the data presented to these related records.

A titration technique was utilized to determine the equilibrium quotients for the first and second aquation steps of cis-Pt(NH/sub 3/)/sub 2/Cl/sub 2/. At 25.0/sup 0/C and an ionic strength of 0.318 M the first and second aquation equilibrium constants are: K/sub 1/ = 3.63 +- 0.22 x 10/sup -3/ M, ..delta..H/sub 1//sup 0/ = 3.4 kcal and K/sub 2/ = 1.11 +- 0.14 x 10/sup -4/ M, ..delta..H/sub 2//sup 0/ = 10 kcal. In the ternary system, cis-Pt(NH/sub 3/)/sub 2/Cl/sub 2/:PtCl/sub 4//sup 2 -/:Cl/sup -/, the kinetics of isotopic exchange of chlorine was investigated. In addition to the expected route of exchange via aquation, a direct exchange of chlorine ligands between cis-Pt(NH/sub 3/)/sub 2/Cl/sub 2/ and PtCl/sub 4//sup 2 -/ occurred which is described by the rate expression. Separation procedures were devised for partial resolution of component yields resulting from dissolving a neutron-irradiated sample of (H/sub 3/O)/sub 2/((Mo/sub 6/Cl/sub 8/)Cl/sub 6/) . 6H/sub 2/O in 1.5 N HCl. A recrystallization procedure was formulated to determine the retention of activity in the parent compound of molybdenum(II) chloride clusters after neutron irradiation. The retention found in an aqueous 1.5 N HCl solution containing 1 percent (H/sub 3/O)/sub 2/((Mo/sub 6/Cl/sub 8/)Cl/sub 6/) . …

This report covers the year 1973, and lists approximately 8,000 articles of interest to mass spectroscopists. This report consists of three sections, a Bibliography section, an Author Index section and a Key Word Out of Context Index (KWOC Index) section. The Bibliography section lists the authors, the title and the publication data for each article. The Author Index lists the authors' names and the reference numbers of their articles. The KWOC Index lists the key words, the reference numbers of the articles in which the key word appears and the first 100 characters of the title.

A laboratory to be used for determining heat transfer coefficients using the technique of laser holographic interferometry (holometry) is described in this report. The basic theory upon which the experimental measurements are based is derived from first principles. Using a relationship between temperature and index of refraction, several cases of free convection in enclosures are evaluated. Results are presented for a heated hexagonal cylinder in an isothermal circular enclosure. In addition, a heated hexagonal cylinder in an isothermal box is evaluated. These provide check cases to some numerical code development which is being done in parallel with the optical measurements laboratory effort. Example holometrograms or holometric interferograms are shown to agree with analytical predictions as to number of fringes in the convective field. For the case of hexagonal cylinder in the circular cross-section enclosure, it is shown that convection has a significant influence upon the temperature gradient (heat transfer coefficient) when compared with thermal conduction. The laboratory will be used to determine heat transfer coefficients in enclosures related to the Liquid Metal Fast Breeder Reactor (LMFBR) Cask Technology Development Program.

An analysis of refrigeration system requirements for the superconducting power transmission cables currently under study at the three principal US cable development centers indicates the need for cable system design considering the interrelated performance of the various cable system elements to successfully develop these systems for commercial operation in the 1990's. Hardware alternatives, compatible with the application timeframe, are evaluated to establish reliable refrigerator system design to a composite requirement typical of the range of refrigerator requirements presented by the cables currently under development. In addition, a methodology is presented and utilized to establish an estimate of hardware reliability and to evaluate redundancy requirements to a specific refrigerator system reliability allocation for a cable system used in previous cable development center studies. Reliability and performance of several compressor systems are evaluated. The oil-flooded screw compressor is felt to be the superior positive displacement compressor; however, the efficiency advantage resulting from preliminary design analysis of a multistage compliant toll process gas bearing centrifugal compressor system indicates a potential major operating cost reduction and the elimination of the need for oil lubrication and its subsequent cleanup requirements. Heat exchangers and expansion engines are evaluated. A preliminary design for a compliant foil process …

This study compared TIE's and TIR's to determine if any important differences exist between them. Salaries, performance ratings, supervisors' opinions, schools, and amount of time to advance from one PEP level to another were compared for the TIE's and TIR's. No statistically significant differences were found. The TIE program provides an important opportunity for members of minority groups and females to move into ESA/SAT level work. 6 figures, 13 tables.

A summary is presented of studies of the heat transfer and pressure drop characteristics of extended surfaces. The summary is based on data that were compiled and analyzed with the objectives of determining the effects of geometrical configurations of an extended surface tube bank on its heat transfer and pressure drop characteristics. A generalized correlation of heat transfer and friction losses was developed on the basis of this analysis. These correlations can be used to predict the performance of an extended surface tube bank of specified geometry and flow conditions.
