An over-all description of the background material on the use of electrical arcs for heating of powders is presented as well as a summary of experimental studies on the arc calcination of thoria. Favorable results have been indicated both with heating thoria powder in an arc heated gas and with thoria formed into a consumable electrode. Use of a consumable electrode produces thoria particles 0.1 to 0.01 mu in diameter. It is recommended that additional electrodes be fabricated and further arc calcination tests be run to produce a quantity of product sufficient for evaluation. (auth)

In many score of experiments conducted in various ways over a period of many months they find that they are unable to confirm the element 102 discovery work of Fields et al. reported in 1957. These experimenters ascribed to an isotope of element 102 an alpha particle activity having an energy of 8.5 {+-} 0.1 Mev and a half-life of approximately 10 minutes. It was reported to be produced by bombardments of a 1 mg/cm{sup 2} curium target with 0.03-0.10 mter-microamperes of C{sup 13} ions of about 90 Mev energy in the internal beam of the Nobel Institute 225 cm cyclotron. Our attempts to reproduce this activity were made with the monoenergetic ion beam available from the Berkeley heavy ion linear accelerator (HILAC). Curium with a similar isotopic composition was used, except that instead of one target they used six separate electroplated targets, four with 0.4 mg/cm{sup 2} curium and two with 0.1 mg/cm{sup 2} curium. These were mounted in vacuum so that the heavy ion beam could pass through and knock the transmutation recoils into 0.9 mg/cm{sup 2} palladium foils. After a suitable bombardment the six catcher foils were dissolved in a few drops of concentrated aqua regia and …

With higher power levels and probably higher river temperatures, the forthcoming warm water season is expected to impose bulk outlet temperature limits, with consequent production losses, on all Hanford reactors to an even greater extent than last year. The problem has received the attention of a number of management and engineering personnel, but the basis for this study was a letter originating in the Production Operation suggesting two alternate schemes for increasing the flow of process water to the rear face piping, thereby reducing bulk temperatures for a given power level. The purpose of the suggestions was to provide an interim solution to the problem pending I & E loadings. Loading with I & E slugs will increase reactor flows to some degree, depending on the actual slug dimensions used, and will probably result in encountering other limits than the B.O.T. limit. The applicable period for study was therefore taken to be this summer only, since I & E loadings are expected to begin in June or July at 105-D and during the fall at 105-F. The Managers, D and F Reactor Operations, requested Plant and Industrial Engineering Operation to investigate and compare the feasibility and applicability of the suggested …

The octant monitors are an improvement over the early sub-pile flux monitors, but they still do not monitor the flux in the active zone of the reactor. Chambers located within the pile active zone would give the desired information but the inpile environment is too severe to allow a reasonable life for these chambers. A beam hole monitor is suggested to provide the desired flux monitoring. The problem of reactor flux monitoring is discussed. The beam hole monitors have the advantage of providing adequate active zone coverage. Calculations were made to show the neutron current and current density at the chamber location as a function of the collimation of the detector assembly. These curves show the present sub-pile and octant monitors are sensitive primarily to the flux in the pile reflector rather, than in the active zone. The beam hole monitors can be made sensitive to the active zone flux only. Sufficient chamber current can be obtained to operate available trip circuitry. It is recommended that experimental work be started to prove out these beam hole monitors so any new reactor program may take advantage of them and that the monitoring of present piles can be improved.

Bubble phenomena have been given a new meaning with their study in relation to the kinetic behavior of reactors. Prior to their study in relation to physics, the bulk of work on bubble phenomena concerned naval engineering problems of behavior in cavitation and water entry behavior. This bibliography is intended to fill the need of the reactor physicist as well as the naval engineer. An attempt has been made to include all available references on bubble phenomena and associated effects. A subject index has been purposely omitted. It is felt that the breakdown in content headings is sufficient to ascertain areas of interest. There will be overlapping of headings and to find all possible entries, a search through the headings may be desirable. To increase the usefulness of this bibliography the location of an abstract has been cited wherever possible following the reference. Classified reports are included; however, their titles contain no classified information. Sources used in compiling this bibliography are: Chemical Abstracts, Industrial Arts Index, Applied Mechanics Review, Nuclear Science Abstracts, the AEC Abstracts of Classified Literature, the AEC card catalogs available at Atomics International, and the bibliographic services of Armed Services Technical Information agency.

In a recent report, means of circumventing the present bulk temperature limits are suggested. These have definite merit but do not present an over-all picture of the problem. Therefore, this bulk temperature limit is reviewed in order to place the problem in its full perspective. A program of action is suggested that should lead to: Revised operating conditions and process piping to obtain higher power levels at the same bulk outlet temperature; The completion of production tests to permit higher bulk outlet temperatures with no significant changes in reactor piping; or Redesign of the effluent system to eliminate bulk temperatures as a reactor operating limit.

"A theoretical method is presented for predicting the dynamic lateral stability characteristics of an airplane towed in tandem by a much larger airplane. Values of period and time to damp to one-half amplitude and rolling motions calculated by an analog computer have been correlated with results of two experimental investigations conducted in the Langley free-flight tunnel which were part of a U.S. Air Force program (Project FICON) to develop a satisfactory arrangement by which a bomber could tow a parasite fighter. In general, the theoretical results agree with the experimental results" (p. 1).

Development work was continued on the fused fluoride process for the recovery of enriched uranium from zirconium-matrix fuel alloys. The alloy is dissolved by immersing it in molten sodium fluoride-zirconium fluoride at 600°C and passing hydrogen fluoride vapor through the system.The dissolved uranium tetrafluoride in the melt is then volatilized as uranium hexafluoride by sparging with fluorine. The uranium hexafluoride product is purified and decontaminated by fractional distillation. Additional corrosion tests were made on a variety of metals in an effort to find a material of construction suitable for the fluorination step. All the metals tested, with the exception of Hastelloy B, were attacked rapidly in the fluorinated melt. The attack was particularly severe at the melt-gas interface when tests were made with partially submerged specimens of the metals.
