The September, 1958 monthly report for the Chemical Processing Department of the Hanford Atomic Products Operation includes information regarding research and engineering efforts with respect to the Purex and Redox process technology. Also discussed is the production operation, finished product operation, power and general maintenance, financial operation, engineering and research operations, and employee operation. (MB)

The design features and the performance of UO/sub 2/SO/sub 4/ blanket processing Loop P-1 are evaluated from an engineering viewpoint. This unique experiment development loop was operated with pump heating to study the behavior of plutonium in 1.4 M UO/sub 2/SO/sub 4/at 250 deg C and was designed for mixed O/ sub 2/-H/sub 2/ gas pressurization The canned loop and the feed and sampling systems in glove boxes completely contained the plutonium throughout the experimental program.

A discussion is presented of the macrostructure of the chloroplast insofar as it is known and knowable by means of microscopy (visible, ultraviolet and electron). This leads to a number of principles of structure to be found in the granum universally distributed throughout the plant kingdom. A chemical analysis of the constitution of these lamellar structures leads to a deduction of structural principles for such molecules as are found therein. The application of these structural principles to the visible structure of the lamella leads to a microstructure on a molecular level of these lamellae which, in turn, leads to a theory of their function.
