Aerojet Nuclear Company performed an experiment at the Westinghouse Canada Ltd. water loop to try to verify the performance of a Transit Time Flowmeter to ultimately measure two-phase flow rates. The recorded data from that experiment were made available and analyzed at Argonne National Laboratory using a transfer function cross-correlation technique. The theoretical background for the transfer function method of analysis and the results of the data analysis are presented. Strong correlation peaks, which are very close to the expected delay times, were found in certain portions of the data.

This is a summary of the techniques used and the results obtained in the study of creep at high pressure, pressure dependence of yield stress and elastic constants, etc. 58 references. (DLC)

The effects of fast flux (E greater than or equal to 1 MeV) neutrons on zirconium and dilute zirconium alloys are discussed. The effects on the elastic constants, strength and ductility, creep, fatigue and fracture, and irradiation growth are reviewed. (FS)

This annual report is organized to follow the task statements of the contract. The summaries are very brief, containing only the most significant results and conclusions. Further information, including the primary data, can be obtained from the quarterly reports. Subjects summarized in this report are microreactor development; catalytic hydrodesulfurization; catalytic hydrodenitrogenation; characterization of aged hydroprocessing catalysts; and microreactor engineering. Tables showing the time plan and milestone chart and cumulative expenditures are included. (EJH)

The high-pressure liquid-phase flow microreactors are operating satisfactorily in both hydrodesulfurization and hydrodenitrogenation studies after minor modifications to allow in situ sulfiding. The hydrodesulfurization of dibenzothiophene occurs by a simple network giving only H/sub 2/S and biphenyl as primary reaction products. The reaction network for quinoline hydrodenitrogenation has been determined, and a kinetic model developed to allow quantitative determination of the first-order kinetic constants for each of the steps in the reaction network. The effect of H/sub 2/S concentration, hydrogen pressure, quinoline concentration, and catalyst type on the rate of the various steps in the reaction network has been determined. Aged catalyst from the 1.1 in ID Synthoil reactor showed considerable amounts of mineral matter on it, but not as much FeS/sub x/ as on the catalyst from the /sup 5///sub 16/ in. ID unit. Moment analysis for the evaluation of pulse microreactor data has been completed.

Approximate expressions are given for the luminosity for different collision geometries and for various beam conditions and ring parameter values. Estimates are made in the case of the main ring colliding with the doubler.

In home range studies, the statistical analysis of radio telemetry data poses special problems due to lack of independence of successive observations along the sample path. Assuming, however, that such data is generated by a continuous, stationary, Gaussian process possessing the Markov property, then a multivariate Ornstein-Uhlenbeck diffusion process is necessarily the source and is proposed here to be a workable model. Its characterization is given in terms of the typical descriptive properties of home range such as center of activity, homing tendency, and confidence regions. Invariance of the model with respect to the choice of an observational coordinate system is established, while data for twin deer is used to illustrate the manner in which the model may be used for the study of territorial interaction. An approximate maximum likelihood procedure is proposed for estimation purposes, with results being reported for deer, coyote, and bird tracking data. Estimates based on the coyote tracking data are used to illustrate how the concept of statistical information may be utilized to examine various sampling strategies.

A new and potentially useful statistical tool for epidemiology is introduced and some of its elementary properties are considered. The technique is a promising one for both data-analytic and inferential problems. Starting with the collection of isopleths of a spatially distributed explanatory variable (air pollution), the method produces a relationship between the explanatory variable(s) and the response variable (population-adjusted health effects) by accumulating the response within successively wider isopleths. Among other appealing features, the method has some of the flavor of regression, reduces the relationship between three three-dimensional distributions to a single easily interpreted two-dimensional graph, and effectively utilizes knowledge of the geographic location of data before discarding the location coordinates as nuisance parameters.

Surface temperatures in electron beam welding cavities in stainless steel 304 and aluminum 1100, 2024, and 6061 were measured with a narrow band infrared radiation pyrometer. A special device was designed for mounting the radiation-sensing probe next to the electron beam gun in the welding chamber. This mounting device included a mechanism for oscillating the probe so as to scan the cavity region both perpendicular and parallel to the welding direction. At the center of its movement the probe viewed almost directly down into the welding cavity. The effect of interreflections occurring in the welding cavity were accounted for by the use of an apparent spectral cavity emittance. Typical measured cavity temperature distributions for SS-304 ranged from 1950/sup 0/C at the mouth to a peak of 2350/sup 0/C at the cavity base and from 1300 to 1650/sup 0/C for A1-1100. First approximation predictions of the cavity surface temperatures were determined by assuming a quasi-steady-state condition. The surface temperature is then a function of the vapor pressure, which is required to balance the surface tension and the hydrostatic pressure both of which tend to collapse the cavity. Base temperatures thus predicted were about 5% and 10% higher than measured for SS-304 …
