Results of a preliminary design study for a solar-powered irrigation facility to be located on a farm between Phoenix and Tucson, Arizona, are presented. The ERDA-specified generic design criteria are detailed. A detailed systems analysis is presented, and preliminary designs of the thermal storage system, organic Rankine cycle power system, cooling water system, power distribution system, and collector foundation are given. Site layout and improvements are described, and a cost analysis of prototype and production units is included. Engineering drawings are included. (WHK)

Data from air tests conducted on the 1/5-Scale Model Mark I Pressure Suppression Facility at Lawrence Livermore Laboratory were analyzed for the purpose of determining the various sources of load signature characteristics. It was determined that hydrodynamic vertical loading function embodies effects from: (a) momentum flux associated with flow from the downcomers; (b) momentum rate associated with bulk pool motion; and (c) unbalanced internal pressure forces related to phenomena associated with vent clearing. The integral form of the linear momentum equation is used to derive qualitative and quantitative insight into the mechanics of the hydrodynamic loading function. Amplitude spectra derived from Fourier transformations show that the 25 Hz (approximate) structural mode is the only frequency which appears consistently in all wave forms which were spectrum analyzed.

This report presents the measured elastic-plastic-creep responses of eight simply supported type 304 stainless steel beams and circular plates that were subjected to time-varying loadings at elevated temperature. The tests were performed to provide experimental benchmark problem data suitable for assessing inelastic analysis methods and for validating computer programs. Beams and plates exhibit the essential features of inelastic structural behavior; yet they are relatively simple and the experimental results are generally easy to interpret. The stress fields are largely uniaxial in beams, while multiaxial effects are introduced in plates. The specimens tested were laterally loaded at the center and subjected to either a prescribed load or a center deflection history. The specimens were machined from a common well-characterized heat of material, and all the tests were performed at a temperature of 593/sup 0/C (1100/sup 0/F). Test results are presented in terms of the load and center deflection behaviors, which typify the overall structural behavior. Additional deflection data, as well as strain gage results and mechanical properties data for the beam and plate material, are provided in the appendices.

This is a state-of-the-art report on the thermal-hydraulic effects of flow-channel blockages in liquid-metal fast breeder reactor (LMFBR) pin bundles. Most of the experimental and theoretical studies for simulating blockages in various prototype LMFBR fuel assemblies done in the United States and abroad through 1976 are presented and summarized. A brief summary on blockage detection is included.
