Report discussing variations in comparative tests of portland cements that could lead to the rejection of a material fully conforming to specification requirements, or the acceptance of a material with undesirable chemical or physical properties. Many of the causes for variation in chemical analyses and physical test results are listed in this discussion, and remedies for some of the more frequently encountered deficiencies in apparatus and methods are suggested.

Report evaluating the technical and economic feasibility of four zirconium fuel processes: the present STR process, the modified Zirflex process, the barium fluozirconate process, and the sodium formate process.

Quarterly progress report on metallurgy research operations at Hanford Atomic Products Operation in Richland, Washington.

A test on the Shippingport PWR was described, whose purposes were to determine if sufficient reactivity was present in the core to override a peak xenon transient, and to obtain data for rod worth calculations. Equilibrium xenon was established at 60 Mw net electrical output for approximately 35 hours prior to shutdown. The flux was then reduced to approximately 100 mu mu a. The reactor was maintained critical by withdrawing or inserting rods as necessary. Startup rates were measured by a mu mu ammeter. The xenon transient was followed in this manner for 60 hours. Override of peak xenon occurred 8 hr 50 min after shutdown. (auth)

A philosophy for designing wideband multistage transistor amplifiers is discussed. The amplifier is visualized as an integral unit, the interstage networks constituting the elements of the amplifier unit. By designing the amplifier as a unit and adjusting the over-all response (gain and bandwidth) with the interstage time constants, an increase in gainbandwidth product is realized over the iteratively designed amplifiers. The resulting increase in gain- bandwidth product results from absence of the bandwidth shrinkage factor for multistage amplifiers. Formulas are derived for both a two- and three-transistor integrally designed wideband amplifier, in which shunt peaking networks are used for coupling. Experimental amplifiers were constructed following these formulas, and the observed performance agreed with the calculations. (auth)

Editor please delete 26456.<><DSN>16:026457<ABS>Work done in the P122 reactor control actuator area is summarized. Actuators were required to radially position the absorber blades in the core of the reactor. The P122C1 was a subsonic power plant and temperatures were low enough to permit the use of hydraulics in the actuator area. The program was reoriented and the power plant designated P122C3 which was a supersonic version of the folded flow power plant. The ambient temperature at maximum power was high enough to require pneumatic actuation of the control blades. The program was reoriented after two design iterations of the subsonic power plant. A test model of the actuating equipment and the entire linkage assembly was on hand and completed when the program was cancelled. The linkage was being redesigned for the supersonic application and special bearings were ordered for fabrication into the lower temperature rig. The actual mechanical concepts of the pneumatic actuator were under study when the program was cancelled. (auth)

Process and product requirements to be met in the fabrication of Type 3 fuel elements are presented. The fuel elements specified consist of thin plates of a dispersion of highly enriched UO/sub 2/ and ZrB/sub 2/ in a stainless steel matrix which is clad with stainless steel on all surfaces. Quality assurance provisions are discussed. Process and material specifications and packaging and packing for shipment are described. Sample calculations and drawings are included. (M.C.G.)

This report addresses the comparison of SNAP-50/SPUR System with MHD, Brayton, boiling reactor and thermionic systems.

Four zirconium fuel processes -the present STR process, the modified Zirflex process, the barium fluorzirconate process, and the sodium formate process-were evaluated in detail for technical and economic feasibility. The evaluation was based on installation as the second generation ldaho Chemical Processing Plant zirconium process. Two nonaqueous processes, the ARCO and the fused salt fluoride volatility processes, were included in a preliminary evaluation, but were eliminated on the basis that major problems inherent in the processes are not yet solved. A continuous version of the STR process was concluded to be the leading contender for rmmediate plant applicator. (auth)

As a means of reducing the quantity of radioactivity released to the environment by radioactive liquid waste discharges at ORNL, it is proposed that two 50,000-gal stainless steel storage tanks and a 600 gph stainless steel, submerged-coil evaporator be installed. The tanks, approximately 10 ft in diameter by 85 ft long, will be equipped with cooling coils attached to their outside surfaces for removal of a maximum of 300,000 Btu/hr of decay heat, and will be supported inside a concrete vauit for containment. The evaporator and a feed tank will be installed inside a cell shielded with 5 ft of concrete and will process mainly intermediate-level waste from the concrete tank farm, but will be able to evaporate high-level waste as well, if required. Two additional cells for the condenser and other off-gas equipment will be housed with the evaporator cell in a building with an operating area and sampling gallery. The capital cost of this installation is estimated to be 226,000. (auth)

References to the data and a brief resume of the methods used in generating cross sections stored on magnetic tapes in fine energy detail are given. The data are used directly in bare, homogeneous reactor slowing-down calculations or can be processed to provide multi-group of multi-level cross sections in coarser energy detail for other machine programs. Cross sections for 33 elements or isotopes, the U/35 prompt and total fission spectra, and the Be(n,2n) transfer cross sections are currently available. (auth)
