Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California (open access)

Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California

From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951.

Development of the Hanford Slave Manipulator for Use in the Multicurie Cells at Hanford (open access)

Development of the Hanford Slave Manipulator for Use in the Multicurie Cells at Hanford

Introduction: "During the early planning of the multicurie cells at Hanford it was decided that a slave type manipulator would be necessary to perform the experiments for which the cells were being designed. The design required steel roofs for installation through a port hole in the face. Technical Services Equipment Development began developing the proposed manipulator in January 1951 by making a study of those existing at that tune. None met the requirements which had been established; therefore, the design of a special manipulator was started immediately."
