Scavenging of Particulate Matter in Connection with Nuclear-Powered Ships

Description: Gases, aerosols, and hydrosols are the forms of particulate matter which might be released from nuclear powered ships. Methods for scavenging these materials were studied in detail. Visual and radar techniques were used in tracking gases and aerosols in the free atmosphere. Scavenging of radioactivity dispersed in substitute ocean water by a permanganate-ferrous salt system was studied. A schematic diagram of a pneumatic conveying system for this type of scavenging material is provided.

Strain Cycling Tests of Large Specimens of AISI Type 347 Stainless Steel and 2-1/4 Croloy

Description: Twenty-one specimens one in. in diameter were tension-compression strain cycled to failure. Six specimens had transverse holes. Load-strain and load-time records were made. The unit strain ranges used were 0.026 and 0.09. The stainless steel specimens were tested at 662 F (350 C), the 2-1/4 Croloy specimens at 850 F. The cyclic life of a specimen with a hole can be predicated from smooth specimen tests by using the elastic stress concentration factor increased by 15%. In the commonly used expon… more

Processing of the Cotter Blend of Colorado Front Range Uranium Ores

Description: The results of laboratory and pilot plant alkaline leaching of the calcareous Cotter Blend are described. The Cotter Blend composition is given in relation to the source and chemical composition. It was demonstrated that specification-grade yellow cake with high recovery of uranium could be produced from Cotter Blend by a pressure alkaline leaching process. A pressure leach under oxygen pressure followed by caustic precipitation recovered 93.1% of the Uranium. (J.R.D.);

Low-Energy [pi] Mesons in the Cosmic Radiation

Description: The intensity of 𝜋 mesons in the atmosphere is investigated in the energy region 𝐸kin≲50 Mev at sea level and at mountain altitudes. Positive 𝜋 mesons coming to rest in an absorber-scintillator are identified by the characteristic 𝜋−𝜇 decay. They are detected electronically and recorded photographically. The value 1.45±0.09 is adopted for the negative-to-positive ratio at small energies. The omnidirectional intensities 𝐽𝜋+ of slow positive 𝜋 mesons at sea level (91m), Echo Lake, Colorado (326… more

Prescoping Optimization for Selection of Enriched Uranium Gas-Cooled Power Reactor Design

Description: A preliminary set of performance calculations were made for enriched reactor cores based on five cylindrical vessel designs ranging from13 to 36 feet in diameter. The capital costs per kilowatt of electrical plant output as shown in Table II indicate than an economic optimum selection of pressure vessel size should be either the 25 foot or the 36 foot vessel.

New Developments in the Theory of Pressure Broadening

Description: An investigation was made into various branches of the theory of pressure broadening by solving two problems: that of treating the motion of the perturbers quantum mechanically and that of overlapping lines. Both problems are solved only in the impact approximation, but this is adequate when the perturbers are electrons, which is the practical case. In addition, the validity conditions of this approximation are examined. (auth)

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.

Attempts to Delineate Inborn Anemias in Mice. Progress Report and Fifth Renewal Proposal, Report Period: January 10, 1959-January 31, 1960. Renewal Period: May 1, 1960-April 30, 1961

Description: During the past year, three papers covering results of a major series of experiments on intergenotype of blood-forming tissue have appeared, demonstrating successful implantation of isologues normal cells in anemic hosts, permanently correcting their genetic defect in hematopoiesis, both with and without irradiation of the host. Heavy host irradiation was shown ineffective as preparations for implantation of homologous cells of widely different antigenic types.
