The Chemistry and Nuclear Chemistry of the Heavy Elements : Progress Report No. 4

Description: This progress report covers the work on the project approximately between the dates June 1, 1058 and May 30, 1959, and is being submitted ahead of the contractual expiration date to support the request for renewal action. During the previous year work has continued to progress in the nuclear and inorganic sections of our heavy element group. The low-level counting equipment will make it possible to extend our fission studies to much lower energies. The U235 and U236 alpha induced fission is ess… more

Concentration of Plutonium by Cation Exchange -- Stabilization of Pu(Ill) in Nitric Acid

Description: Technical report. From Abstract : "Ascorbic and isoascorbic acids, used in conjunction with sulfamic acid, reduced Pu(IV) rapidly and completely to Pu(III) in solutions of nitric acid. The solutions of Pu(III) were stable. Aminoguanidine sulfate also retarded the oxidation of Pu(III) but did not reduce Pu(IV)."

Manganese Dioxide Precipitation in Uranium - Aluminum Nitrate Solutions

Description: Technical report. From Abstract: "Precipitation of manganese dioxide in solutions of uranium-aluminum alloy effected maximum removal of fission products when the alloy solutions were acid deficient. Minimum adsorption of uranium and minimum volume of centrifuged MnO2 were obtained by precipitation in acidic solutions with vigorous agitation."

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.);

A Synopsis of Studies Related to Tritium Monitoring and Personnel Protective Techniques

Description: Technical report issued by E. I. du Pont de Nemours & Co. From Abstract: "Information obtained from investigations pertinent to tritium monitoring and protective measures at the Savannah River Plant are given. These findings were used to establish realistic protective techniques and consequently, to insure the safety of workers exposed to this hazard. Topics included are: contamination, permeation of plastics and rubber, instrumentation, and biological and physical aspects."

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

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.

Determination of the Chemical Characteristics of the 1C Boiler. Test Results DL-S-209. Section III

Description: The purpose of the test was to determine the chemical operating characteristics of the 1C Boiler. The results of the tests performed on the 1C Boiler prior to the installation of new riser indicated that definite chemical hideout existed during full load operation of the boiler. Measurement of local concentrations further indicated that a stabilized steam picket existed in the upper region of the heat exchanger adjacent to the inlet tube sheet during high steaming rates. Since these test were p… more

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
