A study has been made of various types of artificial lightning test facilities required to produce an output current waveform of 1 x 50 microseconds with a 200,000 ampere crest current, representing a very severe natural lightning discharge.

The purpose of a heat shield is to protect the payload from thermal damage during high speed atmospheric reentry.

The Lewis Research Center of the National Aeronautics and Space Administration initiated a project at Battelle Memorial Institute for the purpose of fabricating clad fuel pellet containment vessel assemblies. These assemblies house clad fuel pellets containing enriched fuel. Irradiation studies of these assemblies in the NASA Plum Brook Reactor will provide data required for the desigi of thermionic converter reactors being considered by NASA. Three major objectives were defined at the initiation of this project at Battelle. These were (1) to provide containment vessel assemblies for irradiation studies, (2) to identify the best fuel dispersion/cladding combination for the fueled pellets, and (3) to identify and optimize the most promising fabrication technique to the extent necessary to provide reproducible specimens. In addition to these major objectives, other goals were defined in relation to supporting studies required for the successful conclusion of this program. The approach for accomplishing these objectives involved the cooperation of various research and research support groups at Battelle. These groups contributed to the overall program by involvement in the following areas: (1) Preparation or procurement of various types of UO{sub 2} fuel particles; (2) Application of tungsten coating to the fuel particles; (3) Development of various powder-consolidation techniques …

Abstract: "Geodimeter surveys were made on four traverses near the east scarp of Rainier Mesa between October 27, 1967 and April 26, 1968. These measurements were made in order to determine if an changes in distance between survey stations had resulted from downslope creep of the rocks behind the scarp, or if any displacements had resulted from nuclear explosions beneath the mesa and in adjacent areas. A persistent small but possibly significant, slopeward displacement was measured along one traverse and may represent detachment of a large block; monitoring for an additional period of time is recommended."

From preface: This report contains a fundamental approach to nuclear physics prepared to introduce basic reactor principles to various groups of non-nuclear technical personnel associated with NERVA Test Operations.

This document reports on direct AEC sponsored programs (Columbia River studies); assistance to Douglas United Nuclear (N-Reactor); assistance to Atlantic Richfield Hanford Company (Purex Process, B-Plant, Z-Plant); and technical assistance to the Hanford Plant (environment, dosimetry).

Process Physics Unit has investigated in our sphere of responsibility the changes in reactor operating methods which would result in lower personnel radiation exposure. Reduced spline usage is the only innovation I can suggest for reducing personnel radiation accumulation.
