Investigation of the Photochemical Method for Uranium Isotope Separation

Description: To find a process for successful photochemical separation of isotopes several conditions have to be fulfilled. First, the different isotopes have to show some differences in the spectrum. Secondly, and equally important, this difference must be capable of being exploited in a photochemical process. Parts A and B outline the physical and chemical conditions, and the extent to which one might expect to find them fulfilled. Part C deals with the applicability of the process.

H.E.W. - 300 Area - Metal turnings - Fire hazard

Description: This memorandum discusses means to extinguish magnesium fires in metal turnings at the Hanford Engineer Works 300 Area. The storage of metal turnings in 55 gallon drums presented a fire hazard, for which an effective means for extinguishing the fire had not been presented. This memorandum is dated July 1943. (JL)

The Effect of Radiation on the Corrosion of Metals by Water. (Problem No. 322 MLC 2213)

Description: Long-time tests have been made on the effect of various types of radiation on the corrosion of 2S aluminum in simulated W water. In no case was any acceleration of corrosion by the radiation observed; the effect of radiation, if any, appeared to be a protective one. Deuteron irradiation did accelerate the corrosion of mild steel at low flow rates in hot water of pH 6 to 7, but no appreciable effect was observed with copper, stainless steel, or tuballoy. The general theory of the effect of radia… more

Building 313 operations

Description: On June 3 the writer was detailed to the 300 Area to study operations in Bldg, 313. Seven days were spent with C shift in the caning and dipping area. In this period, a system of coordinating press cycles was developed to utilize machine time most effectively. Subsequently, a brief amount of time was spent working in a design of the can cleaning area so as to incorporate the aluminum can etching operation and facilitate the handling and flow of materials. The next stage of perhaps a week was de… more

Explosives TNX Technical Division, Hanford weekly report for period ending July 25, 1944

Description: Progress on finding suitable water conditions for start-up had been approached as closely as possible with our present equipment and information as to the requirements. The water composition should be attainable that is not corrosive or build up a film rapidly, and we have means available for removal of such films. Slug classification methods were analyzed from a dimensional standpoint. Analysis of current CMX data was undertaken with the objective of establishing allowable variations in pressu… more

Source of high activity levels recently observed from shipping containers and transfer cans

Description: Shipping cans containing product from plant runs completed in the latter half of April and in May showed, in general, definitely higher levels of radiation than had been observed previously. Likewise, containers for the transfer of the F-10-P solution from the 224 Bldg. to 231 Bldg. (during May) exhibited higher radiation levels than could be attributed to higher power levels and increased batch sizes. These higher radiation levels were indicative that some radioactive element (or elements) was… more

Consequences of high power levels

Description: This memo discusses the effects of advancing to higher power levels of the 105 Piles (D-Pile). It is concluded that there is no technical reason against a cautious advance to higher powers; the units can be run at higher levels than their rating of 250 MW, or the additional reactivity that they will gain with time may be taken entirely in the form of lower peak temperatures and radiation levels. The decision as to what course to follow between these extremes involves such issues as the best use… more

Pile power level

Description: A memorandum prepared by the Technical Department discussing the technical considerations involved in raising Pile power above the present level of 280 M.W. was discussed. A meeting attended by W. O. Simon, B. H. Mackey, L. Squires, H. Worthington, C. N. Gross, W. E. Jordan and M. H. Smith. The details of this memorandum were reviewed and the plan proposed for operation of the piles subsequent to August 1, 1945 is discussed in this report.

Studies of the hemolytic effect of radiation

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 cataboli… more
