This monthly report from Savannah River Plant presents information on current activities at the 100 Area (reactors), 200 Area (separations plants), 300 Area (reactor fuels fabrication) and the 400 Area (heavy water). Also, utilities and general services present administrative, technical, and general information. The power ascension program and productivity improvement program are emphasized in the 100 Area report. Tritium processing, 200-F increased capacity, waste disposal, and the `25` process are described in the separations plant report. The increased productivity program in reactor fuels fabrication is described. And progress at the Dana plant and Savannah river plant on heavy water production is described.

This document presents monthly progress at the Savannah River Plant in the 100, 200, 300, and 400 Areas. In the 100 Area (reactors), the power ascension program, the productivity improvement program and general progress is given. Tritium processing, 200-F increased capacity, and waste disposal are reported for the solvent extraction plants in the 200 Area. The increased productivity program is reported for the 300 Area. Dana plant activities and 400-D progress are reported in the 400 area report (heavy water).

This monthly report from the manufacturing division presents progress on operations at Savannah River plant. Reports are given from the reactors, separations plants, reactor fuels fabrication, and heavy water production. Administrative details are also given from utilities and general services.

This document is the February 1956 Monthly Report of the Process Section/Manufacturing Division at the Savannah River Plant. It contains information on activities in each of the SRP areas (100-400 areas), as well as on utilities and general services.

This report presents details of the operations of the Savannah River Plant manufacturing division during the month of June 1956.

This document is the May 1956 monthly report of the Process Section/Manufacturing Division at Savannah River. It contains information on activities in each of the SRP areas (100-400 areas), as well as on utilities and general services.

This report presents details of the operations of the Savannah River Plant manufacturing division during the month of July 1956.

This monthly report details activities of the Manufacturing Division for the month of April 1956.

Progress is reported in these areas: fabrication of Ni-Mo base alloys; tensile tests; oxidation studies; dynamic corrosion studies; production of commercial size heats of Ni-Mo base alloys; brazing of alloys; and fabrication of thermal convection loops.

Increased activities in Cryogenic Engineering have brought about the need for a compilation of available data. The purpose of the Cryogenic Data Book is to provide a condensed source of reliable data and reference information for those working in the cryogenic field. Specifically the data were compiled with a view toward the design of liquid hydrogen bubble chambers.

Methods are described for metallographic preparation of binary U alloys having small percentages of Mo, Nb, or Si. Details are given of mounting, attack- polish technique, and electrolytic etching. Photornicrographs are shown of sintered specimens of U--Mo and U--Nb and of a cast specimen of U--Si. (auth)

The KPL No. 6, first-cycle Purex lA flow sheet is presented as an examaple of waste volume reduction through optimum solvent-extraction flow sheet design. Calculated on the basis of previous flow sheets, a 54 to 69% reduction of first-cycle waste storage volume is achieved by taming advantage of the extractability and reflux of nitric acid in TBP systems to provide adequate salting while minimizing the amount of acid going to waste. Although this report is concerned only with the first Purex cycle, the calculations are equally valid for the second U cycle, and the principles presented are applicable to similar nitnic acid-salted TBP systems.

The activities of the Technical Division, including the HNO/sub 3/ recovery process, a study of UO/sub 3/ factors as related to the production of metal-grade UF/sub 4/, a thermobalance investigation of starch as a reducing agent for UO/sub 3/, reduction of UF/sub 4/ to uranium by a thermite type reaction, melting and casting of Nb-U alloy, uranium recovery from scrap materials, preparation of uranium shot, cal cium reduction of ThO/sub 2/ production of thorium ingots, "wet chemical" and spectrochemical development, ammonia precipitation and filtration studies from uranyl nitrate solutions and preparation of active UO/sub 2/ from UF/sub 6/ are reviewed.

A description of the four-toroid rotator, a relatively simple apparatus particularly applicable to the determination of the corrosive effects of flowing solutions or slurries on structural materials, is presented in detail. In this apparatus flow of a liquid medium at known velocities is induced in a circular section of pipe without the use of pumps. Included are details of mechanical design, descriptions of equipment and instrumentation, a list of fabrication costs, and a discussion of operational experience. (auth)
