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 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 …

Report describing a game software to assist with teaching project management by simulating various decisions and providing options.

The following report discusses thorium and rare earth resources in the Lemhi Pass thorium area where over 200 samples were collected.

The technical concept for Project Travois contains one simple analysis of the potential hazard of contaminating the Arrowrock Reservoir on the Boise River with some of the radionuclides produced. This previous analysis assumes homogeneous and prompt mixing of all the tritium and tungsten isotopes. This simple analysis is physically unrealistic sine there is no way of transporting all of these radionuclides to the reservoir, promptly. We shall in this paper reanalyze the contamination problem in such a way that we define the type of site geology and hydrology information that must be developed.

The Building Electrical Power System, transmits, distributes and controls the electrical power utilized by the equipment of all of the FFTF system. Included are system functions and design requirements, the physical description of the system, safety considerations, principles of operations, and maintenance principles.

This report's purpose is to present the constitutional and historical background of the "interregnum" question and to describe the precedents established on these occasions. It discusses when the date set for the inauguration of the president has fallen on a Sunday.

This report gives some general background on the history of the District Government, and to outline some of the arguments, pro and con, on the issue of representation for the District of Columbia.

This report gives the status of production tests control tube loadings in reactor process tubes containing significant amounts of SS material. Data are given in table form. For further description of column headings and the current discharge goal exposure plan refer to Document DUN-3443.
