Letter opinion issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, John Ben Shepperd, regarding a legal question submitted for clarification; Constitutionality of House Bill 573 of the 54th Legislature

"In the development of high temperature materials of the brittle category, the need to improve their impact strength for some applications has brought with it a demand for a simple machine for measuring impact resistance, both at room and elevated temperatures, and preferably one in which corrections such as the toss energy are negligible. This report describes such a machine and presents the results of some preliminary tests on the effect of temperature on impact strength of several alloys and cermets. A comparison is also given between the impact resistance of notched and unnotched specimens" (p. 1).

Report presenting information on the engine performance variations resulting from bleeding air from the compressor for turbine cooling, which is currently lacking. A thermodynamic-cycle investigation was conducted to determine the magnitude of the performance variations for a wide range of operating conditions for turboprop engines and for both afterburning and nonafterburning turbojet engines.

Report presenting an exploration of fuel temperatures, which includes variables such as the aircraft speed, flight time, flight altitude, materials of construction, location of fuel tanks relative to aircraft skin and hot engine parts, and other factors. The results illustrate that it is impossible to predict quantitatively the fuel temperatures that will be attained in aircraft without detailed design information on each machine.

Nine technical studies were approved for funding. Discussions at the meeting centered around safety and work schedules. Appendices contain information on Financial status, the Separations program, the Analytical Chemistry program, and the Technical Division studies that were approved at the meeting.

This document details activities of the Hanford Atomic Products Operation (HAPO) during 1954.

W.J. O`Leary and R.R. Herries visited BMI in company with C.C. McBride, SRL, to discuss the results of subcontract research on the extended surface fuel element program and to discuss with BMI personnel the programs included in the recent contract extension. A summary of results are given in the following. Double and triple melts from two 9--10 pound ingots of arc-melted Horizon`s thorium showed decreasing porosity. Physical and chemical data, on these as well as on eight previous double melted ingots, are being obtained. The problems involved in obtaining uniform castings of uranium-aluminum alloy for co-extrusion billets were discussed, with emphasis upon those phases to be investigated at BMI. A program was outlined to evaluate the effects of outgassing, by vacuum annealing, on the corrosion resistance of nickel-plated uranium. Data obtained from diffusion studies at BMI show that the mutual diffusion at high temperatures of thorium and aluminum is slow, with the diffusion of the thorium into the aluminum proceeding somewhat faster than that of the aluminum into the thorium. Possible methods of applying an inner cladding of aluminum to a tubular uranium fuel element were discussed. ``Half-dollar`` size uranium corrosion samples, nickel-plated and press-clad with 30-mil aluminum at 10 …

The purpose of this report is to present a HAPO proposal for the design and construction of a high-temperature, high-pressure light water recirculation test facility for the Westinghouse Electric Corporation, Atomic Power Division This report does not attempt to justify the feasibility of site location nor does it attempt to elaborate on such technical considerations as permissible test specimen heat generation and enrichment requirements which have been covered in an earlier document. Instead, detail information is developed on the proposed design with major emphasis on detail descriptions of the proposed loop and auxiliaries, design and construction scheduling and costs, and operating costs.

This report presents details of the operations of the Savannah River Plant manufacturing division during the month of February 1955.
