A Study of Water Plant Isolation From Contamination

Description: From Introduction: "In this study, data has been obtained on radioactive nuclide concentrations in nuclear power plants of both the BWR direct cycle and the PWR indirect cycle. These data, together with leakage rates actually experienced in the PWR steam generators and with assumed leakage rates in brine heaters, are used to calculate concentrations of radioactive nuclides in the water plant product and effluent."

Review of Existing and Potential Test Sites in Areas 18, 19, and 20, Pahute Mesa, Nevada Test Site

Description: Abstract: "Recent request for new sites has prompted an overall review of the Pahute Mesa area. The criteria used in this review are that the geology must be favorable and that horizontal spacing of emplacement holes being developed should be 2.5 to 3 times hole depth. The review shows that current emplacement requirements have exhausted available explored sites and have effectively eliminated 90 percent of the blocks of ground geologically favorable for chambered sites."

Dynamics of Wheeled Vehicles, Report 1: A Mathematical Model for the Traversal of Rigid Obstacles by a Pneumatic Tire, Appendix B: Digital Implementation of Segmented Tire Model

Description: Summary: "This appendix presents the procedures for digital implementation of the segmented tire model, developed in the basic report for an analog computer. Two procedures are required: (a) determination of the segment spring coefficient from measured load-deflection test results, and (b) computation of the resultant force vector transmitted to the axle. Digital programs for both procedures were written in Fortran IV for a GE-420 system, and are included" (p. xi).
