Casting Uranium Bars as a Substitute for the Extrusion Process

Casting Uranium Bars as a Substitute for the Extrusion Process

Date: January 1, 1945
Creator: Lindlief, W. Earl
Description: The usual method of producing uranium slugs for the reaction pile is to cast the metal into billets which are extruded into rod about 1.45 inches in diameter. Slugs are then machined from this to the final size of 1.359 inches in diameter by 8 inches long. Extrusion is done in the gamma range at a temperature of about 1000 C, where the metal is soft enough to be extruded at relatively low pressures. This operation is difficult and expensive and the product is not entirely satisfactory. The billets must be protected from oxidation during heating and extruding and the extruded rod must likewise be protected during cooling. Loss of metal due to oxidation is appreciable and a relatively large amount of scrap is produced. The production of dies suitable for use at the high temperatures involved is troublesome. The extruded rod must be straightened before machining and frequently contains stringers of oxide and voids or other internal defects.

The Direct Pouring of Liquid Metal from the Reduction Bomb

The Direct Pouring of Liquid Metal from the Reduction Bomb

Date: March 9, 1945
Creator: Wilhelm, H. A.
Description: By the time regular crude biscuit production was interrupted at Ames on November 9, 1944, we had made well over 100 special experimental castings by pouring the liquid metal directly from the bomb. The workmen on the regular crude production line were alternating these special castings with the regular runs without the assistance of the research group. The process had reached a state of development 'wherein the castings were made by pouring batches of about 135 pounds of liquid metal directly from the bomb into a water-cooled steel mold in the presence of air at atmospheric pressure. The pouring operation was effected through a mechanically operated valve in the bottom of the bomb. The workability of such a process has been well established, and the quality of the metal has been proved through candling and chemical tests. The first sixty billets produced by this method have been extruded successfully. A number of changes, designed to improve the quality and yield of the product and to simplify the process, have been made since producing the metal for these tests. The first set-up to test the possibility of pouring the metal directly from the bomb was made on a small scale here ...

The Site B Foundry (Final Report on Part I of P.A. No. 151-ML-54-2, F.S. 41)

The Site B Foundry (Final Report on Part I of P.A. No. 151-ML-54-2, F.S. 41)

Date: February 12, 1945
Creator: Lauletta, Paul
Description: The Site B Foundry is equipped for the melting and casting of tuballoy and its alloys. Castings weighing up to 750 pounds and as long as 40 inches can be made. Melting can be carried out in the vacuum, in inert gases or under fluxes. Heating is by high frequency induction. A description of the generally foundry layout, the furnace construction and operation, and of the auxiliary equipment is given in this report. The casting technique used in the Site B Foundry is designed to minimize piping and cold shuts in the billets. The top of the mold is kept hot and freezing of the billet takes place from the bottom. This hot topping minimizes piping. Controlled pouring into warm molds minimized cold shuts.

Monsanto Chemical Company, Unit 3 abstracts of progress reports, August 16--31, 1945: Summary of work to date on volatile neutron source

Monsanto Chemical Company, Unit 3 abstracts of progress reports, August 16--31, 1945: Summary of work to date on volatile neutron source

Date: September 6, 1945
Creator: Rollinson, C.L.
Description: It was proposed to prepare a volatile polonium compound which could be used alone or with another gaseous compound as a neutron source. The objective was to obtain a neutron source which would give off few neutrons in the expanded state, but when condensed would act substantially as a thick target and emit perhaps ten times as many neutrons. Originally, polonium hexafluoride was suggested; with such compound the fluorine atoms would constitute the target. the predicted boiling point of polonium hexafluoride is about -40 {degrees}C. There was reason to believe, however, that lower relatively non-volatile fluorides would be formed rather than the hexafluoride. Polonium alkyls were therefore proposed as alternatives. The predicted boiling point of Po(CH{sub 3}){sub 2} is about 110 {degrees}C. This compound in itself would probably not be suitable as a target material but it could be mixed with other gases such as carbon tetrafluoride, boron trifluoride, etc., as targets. As a longer range possibility, Po(CF{sub 3}){sub 2} was also suggested. This compound would act as its own target and would moreover have the same F/Po ratio as PoF{sub 6}; its boiling point could be expected to be 30{degrees} - 60 {degrees} lower than that of polonium dimethyl. ...

July 16th nuclear explosion: Permanent earth displacement

July 16th nuclear explosion: Permanent earth displacement

Date: October 3, 1945
Creator: Reines, F.
Description: A measurement was made of the permanent earth movement in the neighborhood of the tower caused by the nuclear explosion at Trinity. The crater was apparently formed by a compression phenomenon and was noted to be much shallower than craters formed by ordinary high explosives. Scaling up existing information on the radius of craters, the TNT equivalence of the nuclear bomb is given as 10,000 tons to within 50 percent. Observations were made on the damage in the crater region and suggestions are given as to the nature of structure which might be expected to withstand the blast close to the gadget. It is also noted that, despite previous opinion to the contrary, it is apparently possible to reduce greatly the volume of earth blown away by the blast by suitably protecting the ground.

Studies of the hemolytic effect of radiation

Studies of the hemolytic effect of radiation

Date: July 10, 1945
Creator: Schwartz, S.; Katz, E.; Porter, L.M.; Jacobson, L.O. & Watson, C.J.
Description: These studies were aimed at elucidating affects of radiation in inducing hemolysis independent of inhibition of erythropoiesis. Research studies were conducted both on human patients and dogs. Phosphorus-32 in mc amounts were administered either intravenously or orally to patients suffering Polycythemia rubra vera. Dogs were treated with either P-32 or x-radiation. Hemoglobin metabolism was monitored in all test subjects by hematology, blood chemistry, and fecal excretion of hemoglobin catabolites.

Date: December 31, 1945
Creator: English, S.G.
Description: This May 1945 report deals with how best to estimate the toxicity of ``Product`` to workers at Clinton Laboratories. Discussed are the issues of how toxic product is relative to radium, methods of analysis of product in the body, means of elimination from and distribution of product within the body, and what therapeutic measures are available. The principal concern of the author is that of protection of personnel who regularly handle in the laboratory large amounts of this material.
