The mechanical properties of vapor-deposited thin metallic films are being studied in conjunction with the target fabrication group associated with the laser-fusion energy program. The purpose of the work is to gain an understanding as to which metals are structurally best suited to contain a glass microsphere filled with deuterium-tritium (D-T) gas at large internal pressures.

The transporter cart serves as a dolly to move the large toroids (539 tons) and the Roman arches (600 tons) which are part of the central detector. ANSYS has been used to compute deflections and stresses in this cart.

Requested information is presented concerning the background on the CRBR Project and its plutonium requirements, and analysis of sources and cost of acquiring plutonium for CRBR fuel.

The A.P.T. Dry Plate Scrubber uses a shallow, dense mobile bed of solid collector granules which move across a perforated plate. The gas stream containing fine particles and vapors is moved upward through the perforations to form high velocity gas jets. The fine particles are removed by inertial deposition onto the collector granules or by direct interception. Electrostatic forces also can be used to improve the collection efficiency and increase the adhesive forces between the particles and collectors. The DPS column consists of a series of collection stages (perforated plates) with the collectors either passing sequentially over each stage or being fed separately to each stage. The stages can be designed so as to promote the collection of large particles on the lower stages and the collection of fine particles and alkali vapors on the upper stages. The objective of this project is to conduct a bench scale experimental evaluation of the DPS at high temperature and pressure to determine its potential for controlling particulate and alkali vapor emissions from PFBC processes. The project is divided into two phases and seven major tasks as listed.

This report documents the technical evaluation of the adequacy of the station electric distribution system voltages for the Prairie Island Nuclear Generating Plant, Units 1 and 2. The evaluation is to determine if the onsite distribution system in conjunction with the offsite power sources has sufficient capacity to automatically start and operate all Class 1E loads within the equipment voltage ratings under certain conditions established by the Nuclear Regulatory Commission. The evaluation finds that with some minor transformer loading modifications, hardware changes and the results of equipment testing and manufacturer data, the offsite sources were demonstrated to supply adequate voltage to the Class 1E equipment under worst case conditions.

The results of laboratory experiments involving the flow of two commercial flocculant solutions through Berea sandstone core plugs at 225/sup 0/C are summarized. The two flocculants used are TFL-398 and TFL-362 (commercial flocculants supplied by Tretolite Division of Petrolite Corporation). The flow of brine containing these flocculants through these sandstone cores resulted in considerable permeability reductions during the flow experiments even when used at concentrations of only 5 ppM. The reduction in permeability is attributed to the plugging of pore spaces by the degradation products. The results of these experiments demonstrated that the use of a flocculant can cause severe formation damage. It is, therefore recommended, to always conduct laboratory tests prior to the use of any specific flocculant for geothermal applications to avoid any damage to injection wells.

A method is described for locally rescaling the curvilinear coordinates used in continuous rezoning of Lagrangian meshes by the equipotential method. In this way the zone aspect ratio may be brought closer to unity.

This report gives a detailed description of the input and output of the statistical model code STAPRE for compound-nucleus reactions including a special section on the various level density options of the code. It is to be used in conjunction with the report IRK 76/01 + Add 76 + Add 78 by B. Strohmaier and M. Uhl which describes in detail the physical models on which the code is based and its general organization and structure.

Sodium tetraphenylborate is used to coprecipitate cesium with potassium in the precipitation process that has been developed to decontaminate waste salt solutions. This report summarizes the results that have been obtained.

The need for energy research programs directed toward increasing the cost-effectiveness of energy use is discussed. Benefits reaped by society as a consequence of successful completion of a research activity are economic, environmental, health and safety, security, and long term; emphasis is placed on the economic benefits from research projects on the demand side (i.e., energy end-use sectors). Each end-use sector was examined and data on the amount of energy consumed and the estimated cost of that energy are compiled.
