This report presents the details of the activities of Douglas United Nuclear at the Hanford site during the month of April 1969.

Tests were conducted on an intermetallic compound and a loaded carbon to determine hugoniot equation of state up to 500 kbar at 72 degrees F, using flat-plate impact techniques-- a multiple-wave structure characteristic with an elastic precursor.

This report is designed to provide basic information about an initial analysis of the major economic and demographic characteristics of the eight counties included within the Alamo Area Council of Governments. The uses of this information include primarily the development of a comprehensive Social Planning Program for the area designed to meet the social service needs of the entire metropolitan area.

This report includes Findings and recommendations of a study about Environment, Natural Resources and Population conducted by the committee on Resources and Man of the National Academy of Sciences-National Research Council (NAS-NRC).

This report documents articles that opposed events, buildings, or inventions that are now historically or modernly important, such as the Louisiana Purchase or the invention of the airplane.

This report presents The fees and incomes of physicians according to the public and congressional interest.

The purpose of this report to discuss the rising costs of physicians' services and to examine what effect these increases have had on the practice income of the medical profession.

This document comprises a compilation of preliminary data generated during the reporting months of March, April, May, 1969. Data relate to fuel element development, cladding development, fuel quality assurance, fuels evaluation, and offsite fuel programs.

The major technical bases for the FFTF first core fuel assembly conceptual design are presented in four general categories: (1) thermal, (2) hydraulic, (3) structural and (4) performance-manufacturing design characteristics. Recommended design values and conceptual engineering drawings of the fuel pin and subassembly are included .

Report that "covers the field operation of a 36-in. diameter pressure-vessel-type reverse osmosis system over a seven month period and the post-operational inspection of the unit and associated hardware" - (p. 1).

A series of three tests will be performed to evaluate: temperature gradients between wall and central coolant channels in an FFTF fuel assembly to assess thermal stress level in the pins. The potential hot spot caused by the presence of a wire wrap spacer. A single electrically-heated 7-pin fuel assembly model will be used to perform these tests. The configuration is summarized in Table 1 and the instrumentation in Figure 1. Pins 1, 2, and 7, along with the local coolant thermocouples, characterize the central and outer channels. Pins 4 and 6 provide data on the hot spot under the spacer, while pin 3 (along with pin 2) provides data on the gradient across an outer row pin.

This is the second summary report of Hanford waste disposal experience. The data was tabulated from reports submitted by the contractors to the Richland Office of the Atomic Energy Commission. For a detailed description of Hanford waste management practices and plans the reader is directed to Hanford Waste Management Plans. There were no instances where rates of release exceeded applicable release guides and generally release rates were less than 10% of RL Appendix 0510 guides. There was a general long-term downward trend in releases to the atmosphere and to the river reflecting retirement of production facilities including the 100-B reactor in February 1968, and also reflecting the results of programs intended to reduce releases even further. 14 refs., 6 figs., 5 tabs.

The FTR vessel wall will be cooled with inlet primary coolant which bypasses the core and flows through an annulus formed by the vessel wall and the thermal barrier. heat transfer to the by-pass coolant stream is by raial conduction from the surrounding sodium pool through the thermal barrier wall. In the analysis, the temperature rise of the by-pass coolant stream was derived as a function of the wall thickness of the thermal barrier and the flow rate of the by-pass stream.
