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

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

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.

Design Study: Sodium Modular Reactor (open access)

Design Study: Sodium Modular Reactor

This study was undertaken for the USAEC under Contract AT(04-3)-189, Project Agreement No. 6, to investigate desirable features of a sodium cooled, graphite moderated uranium fueled power reactor using the modular concept, and, based on this investigation, evaluate the economic potential of this reactor type.

Progress Report for Period Covering December 17, 1969 - January 15, 1960

As reported in the previous Progress Report (December 16, 1959) a stock solution of Th 230 was prepared from pitchblende. Pulse height analysis of this solution indicated the presence of only Th 230 (93%), Th 227 (5%), Th 232 (1%), and Th 228 (1%). This solution was used to make up synthetic thorium solution of various concentration. These synthetic solutions were analyzed to establish a chemical yield for the procedure. Neither the precision nor the chemical yield of the procedure were considered to be satisfactory. In the next report period, we hope to complete the testing of the thorium procedure, both with regard to chemical yield and precision, as well as to determine decontamination factor from radium, uranium, and polonium. To do this, pure solutions of polonium, radium, and uranium will be prepared. The polonium and radium will be processed from pitchblende while the uranium will be made by purifying reagent grade uranyl nitrate.

Radioactive Drug Research, Final Summary Report, July 1949 to October 1959 (open access)

Radioactive Drug Research, Final Summary Report, July 1949 to October 1959

Applications of radioisotopes in the preparation of labeled drugs are reviewed. Among the applications described are the preparation of carbon-14- labeled cardiac glycosides, and the biosyinthesis of carbon-14-labeled digitoxin, morphine, colchicine, atropine, podophyllotoxin, and nicotine. The fate and metabolism of many of these drugs were traced. Radiochemical procedures were developed for the synthesis of pure compounds of pharmacological interest labeled with carbon-14, sulfur-35, and tritium. Investigations were made on the phenomena of drug penetration into the central nervous system. Publications during the period are listed. (C.H.)

The SNAP II Power Conversion System. Topical Report No. 3. Dynamic Analysis (open access)

The SNAP II Power Conversion System. Topical Report No. 3. Dynamic Analysis

SNAP II is the designation for a nuclear auxiliary power unit, designed primarily for utilization in the WS117L satellite vehicle. The SNAP II system consists of a reactor heat source, a mercury Rankine engine, and an alternator. Dynamic analysis of the power conversion system was conducted utilizing a comprehensive analog computer simulation. Feasibility of a parasitic load control for numerous system disturbances was demonstrated. This analysis was performed under a subcontract to to Atomics International as part of the Atomic Energy Commission Contract No. AT(11-1)-GEN-8.

Studies of Reactor Containment : Monthly Technical Progress Report No. 32 (open access)

Studies of Reactor Containment : Monthly Technical Progress Report No. 32

The report covers work performed during the period December 1, 1959 through December 31, 1959. The general objectives of the program of "Studies of Reactor Containment" are to accomplish theoretical and experimental investigations of the loads to which external containment structures for nuclear reactors are subjected in the vent of a violent incident at the reactor core, the evaluation of methods of reducing that loading, and the study of the response of and design criteria for external containment structures as a result of such loading. Progress of technical effort during the report period is summarized for each of the eight tasks of the program..
