How Would Adjusted 1990 Census Data Have Made a Difference?: A Case Study of Long Beach, CA

Description: Report estimating how adjusting the data of the heavily-undercounted 1990 census would have affected public policy and funding in Long Beach, CA. The report suggests that the 2000 census data be adjusted to compensate for undercounts to ensure that services get the funding they need.

Natural Circulation Burn Out Heat Flux For The ORR

Description: Natural circulation flow rate is calculated for the ORR core. From this flow rate, the burn out heat flux is found to be between 22,000 and 35,000 Btu/ft2-hr. It is concluded that under present conditions a positive acting after heat removal system is necessary for 30 mw operation.

Progress letter No. 11 for January 1, 1960 through January 31, 1960

Description: A stainless steel autoclave for superheated water corrosion test was installed and "conditioned". Tests were begun to investigate the feasibility of densifying slip cast stainless steel by means of liquid phase sintering. Attempts to prepare tubular fuel elements by vacuum forming were resumed. Although thick-walled vacuum formed casting have been sintered on the aluminum mandrels without cracking, this has not yet been accomplished with the think sections of interest.

Progress Report for Period Covering January 15, 1960 - February 15, 1960

Description: Thorium Procedure: As was mentioned in the last report, ammonium nitrate was substituted for ferric nitrate as a salting agent. Also, the acidity of the nitrate solution was reduced from 3.0 molar to 0.5 molar. the revised thorium procedure is described in the report. Radium Procedure: Work has ben initiated on the procedure of Petrow, Nietzel and DeSesa (Winchester Procedure) to determine if the procedure is suitable for very low level concentrations of radium.

Cyclic Pressure Tests of Large Size Pressure Vessels

Description: This investigation into the plastic fatigue strength of large size pressure vessels is a part of a general research program on plastic fatigue problems in pressure vessels which is being carried out at several laboratories. While the overall program includes identical pairs of vessels fabricated from A-201, A-302, and T-1 steels, the work in progress concerns only the A-201 vessels. This report covers the progress in the period from 15 January 1960 to 15 February 1960.

The Surface Tension of Aqueous Uranyl Sulfate Solutions Between 20' And 75'C

Description: The surface tension of aqueous uranyl sulfate solutions, ranging in concentration from 0.175 molal to 2.340 molal, has been measured at 20', 30', 45', 60' and 75'C. The surface tension increases continually with increasing temperature, becoming in the most concentrated solutions about six percent greater than that for water at the same temperature.

Fabrication Procedure For RaLa Source Fuel Rods

Description: A new method to procure RaLa sources was proposed by Group CMR-10, Los Alamos Scientific Laboratory. This method depended upon irradiation of small-diameter U235 wire in the Materials Testing Reactor, Arco, Idaho. A procedure for cladding and sealing U235 wire in stainless steel tubing, by drawing, plugging the tube ends, and welding, was developed, tested, and proved to be satisfactory.

The Irradiated Rupture Prototype (IRP) Design

Description: One of the problems involved in the design of NPR is the method to be used for decontamination, Considerable effort has been made in both laboratories and pilot plants in developing and evaluating decontamination processes under ideal conditions. Promising processes must be tested under prototypical conditions of velocity, water quality, manner of make-up, type and degree of contamination, addition of decontaminating solutions, and so on.

Absorption by Soil of Strontium From 216-S Crib Waste

Description: A preliminary soil column experiment with a waste sample from the 207-S-11 well, which monitors the 216-S cribs, indicated that cesium was absorbed almost completely by the soil but that strontium breakthrough to ground water in the near future seemed likely. Accordingly, it was suggested that the 216-S wastes be discharged to a new disposal site, and that samples of the wastes which are currently being discharged to the 216-S cribs be obtained for soil absorption tests. The primary purpose of … more

The Alpha Half-Life of the Isotope Pu-241

Description: A plutonium solution of known Pu-241 content was purified by solvent extraction techniques to remove uranium and americium impurities. Portions of this purified solution were then analyzed for U-237 as a function of time. Since the growth of U-237 occurs directly by the alpha decay of Pu-241, these measurements provided sufficient data for calculation of the Pu-241 alpha half-life, which was found to be 2.91 ± 0.50 x 10⁵ years.

Energy Distribution of Fast Neutron Beam

Description: Experimental techniques are described for the spectral measurement of a collimated fast neutron beam. A hydrogen filled cloud chamber, proton recording nuclear plates, and threshold fission foils were used as neutron detectors in the measurements. As an application of the above technique, the energy distribution and absolute flux of the fast neutron beam emerging from port 5W of the Los Alamos fast rector has been measured from 0.1 Mev to 18 Mev. The result show a spectral curve possessing a ma… more
