Investigation of the Photochemical Method for Uranium Isotope Separation
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
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)
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 radiation on corrosion is discussed, with the conclusion that no acceleration of corrosion by radiation is to be expected in most cases of practical interest.

Building 313 operations
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 devoted to a study of inspection and testing methods. The final period of one week was utilized mainly to develop a method of storing finished material so as to provide the maximum amount of piece-classification flexibility without incurring enormous burdens in the movement of material to later stages of the operation.

Explosives TNX Technical Division, Hanford weekly report for period ending July 25, 1944
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 pressure drop in W-tubes due to film formation. Calculations were made of the number of slugs which have jacket temperatures in excess of various values, for various loading arrangements. On July 26 the proposed loading of the discharge nozzle is to be checked on CMX tube 1 during an inspection shut-down. Evacuation procedures in the event of a catastrophe in the 100-B area were discussed with W.E. Rapp during a visit to that area on July 19, 1944. Tests for slug leaks will not be less severe with water in the autoclave than with steam, and have a considerable chance to be more decisive, especially if a wetting agent is added to the water. Calculations were made on the sensitivity to be expected from three …

Source of high activity levels recently observed from shipping containers and transfer cans
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 present in an amount greater than previously as would be expected from the shorter cooler periods, or that decontamination of elements previously present was less complete. It was considered essential to identify the source of these radiations and the cause for their presence has been investigated. The radioactive contaminant present in the final product has been identified rather definitely as Np{sup 239} which has 2.3d half-life a 0.25 MeV gamma ray and a weak beta ray. The amount of Np has increases as a result of the brand toward shorter cooling periods and the law decontamination factor for Np in the Separation Process.

Consequences of high power levels
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 of uranium and the most effective separation of adequate amounts of product of proper quality.

Pile power level
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
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.
