Delays in the start-up of the RefCOM facility in Pompano Beach, Florida, are outlined. The most serious delays involved problems with the screw conveyors. After many modifications had proven futile, it was decided that they were not applicable to the system and the screw conveyors were replaced with a rotary feeder. An itemized, chronological list of all plant modifications including the cost of labor and materials are presented in this report. Diagrams and daily work sheets are included. (DMC)

Quartz sand derived from alluvial fans that drain different lithologies at the Nevada Test Site can be distinguished on the basis of grain shape as described by the Fourier series in closed form. Specifically, we examined tuff units from the Piapi Canyon and Indian Trail Formations as well as carbonate-bearing clastic units from the Eleana Formation. Discrimiation between rock types was accomplished by examining the mean harmonic amplitude spectra and the grain shape frequency distributions at those harmonics that exhibit significant chi-square values. The results of these analyses indicate that the tuffs can be easily distinguished from the clastics. However, differences between samples from genetically similar rock types are not as prominent. Grain shape frequency distributions of tuffs and clastics show such strong differences that they can be characterized by standardized distributions. By comparing the shape frequency distributions of mixed sediment samples, it is possible to determine the relative contribution of tuff and clastics to any sediment sample taken within the drainage network. The Piapi Canyon, Indian Trail, and Eleana Formations have produced the thick alluvium sequence in the Rainier Mesa region of Yucca Flat. We believe it is likely that these grain shape relationships can also be applied to …

Reliable performance of fuels for the Fast Flux Test Facility (FFTF) is of paramount importance for the FFTF program. Improved inspection techniques and processes are essential for controlling the quality of such fuels. Several considerations necessitated the development and application of improved inspection techniques and processes. These include fuel design, throughput rate, and pre-irradiation characterization requirements. Some of the more significant advances are in the areas of fuel pellet dimensional and weight measurements, fuel pin diameter measurements, and on-line, computerized quality status tracking. Advances in each of these areas are discussed.

The design requirements, subsystem characteristics, environmental requirements, and cost and performance evaluation techniques are defined for the Line Focus Solar Central Power Systems. Specific passages revised are enumerated. (LEW)

The second coordination meeting, site visits to the demonstration facilities, and data collection are described. The sites visited are listed. (WHK)

This technical report summarizes a portion of the results on surface radiation properties of reactor materials, which is part of the program on Attenuation of Radiological Consequences From Core Disruptive Accidents by Radiative Transfer. In analyzing radiant energy exchange between the fuel and coolant, it is necessary to know the reflection absorption, and emission characteristics of the fuel and its interface with coolant. Because of unavailability and great uncertainty of those radiation properties, they are calculated from the electromagnetic theory of optics and results are presented here. Depending on the contacting medium, six types of surfaces received consideration. They are the interfaces between uranium dioxide and sodium, uranium dioxide and steel, uranium dioxide and a gas, water and a gas, steel and a gas as well as sodium and a gas. The spectral interface reflectance as well as the spectral absorptance from one side of the medium to the other side is evaluated for all wavelengths. Those spectral properties are further integrated to yield the total hemispherical properties for a black body source over a temperature range of 1200/sup 0/K to 6000/sup 0/K. Comparisons are made with available experimental data or calculated values and the general agreement is found generally …
