Cooling water requirements in 212 buildings

Description: This document provides plots of expected rates of heat evolution rates of heat evolution from irradiated metal which may be useful in estimating the cooling water flow required in the the 212 buildings. A comparison of three sources of data found in the Project Handbook is provided. The CN 526 calculations agree very well with the estimates of 16, 32 and 64 days decay periods. CN 526 information was used for calculating the heat evolution rates shown in the following figures, since the data doe… more

The Direct Pouring of Liquid Metal from the Reduction Bomb

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 f… more

Recommendations for separations processes program

Description: Many questions have been raised concerning the advisability of continuing the presently scheduled Redox design and construction program in performance to other uranium recovery processes. In order to answer these questions properly, an extensive re-examination of the Redox process objectives and status and a careful study of other possible alternative uranium recovery processes have been carried out by the Hanford Works. This survey has included consideration of both existing process and facili… more

Technical Department report on production test No. 313-78-M: Study for evaluation of slug dimensions

Description: The present system of classifying slugs intended for canning provides for individual measurement of dimensions on first-run MZ material, but not for their individual weighing. While the total and average weights of this type of material are determined on batches of twenty, this operation is for purposes of accounting only, and no concern is normally attached to the functional aspects of varying weights. It is thought desirable to obtain information relative to this problem. Collection of such i… more

Determining Load Correction and Correcting Frequency Compensated Constant Voltage (FCCV) Sola Transformers

Description: By test duplicating actual operating conditions the average load was found to have a power factor of 95 percent and to be about 75 percent rated load. Since the Sola transformers must be operating into a load having a power factor of 90 percent and about 85 percent rated to attain proper output voltage, power factor corrective networks consisting of inductance and resistance in series were paralleled with the load. When these networks were added, the desired output voltage was attained. Several… more

Loss of Radioactivity from Barium Carbonate Samples

Description: The exchange loss of radioactivity from solid samplos of barium carbonate through the agency of carbonic acid and its ions has been investigated under a variety of conditions. It is concluded that the losses observed are greatly dependent upon the method of sample preparation, in particular the nature or any heat treatment which the sample materials undergo.

Range Energy Relation for Protons in Nuclear Emulsions

Description: An experimental range-energy relation in Ilford C-2 emulsion has been obtained for proteins up to 39.5 Mev. In the region from 17 to 33 Mev the relation for dry emulsion is fitted by the empirical equation E{sub (MeV)} = 0.251 R{sub ({mu})} 0.581. Variations in water content due to changes in atmospheric humidity make several percent difference in range. The range in Ilford glass is found to be 18 {+-} 4 percent longer than in dry C-2 emulsion.
