Dry scram evaluation

Description: The analysis performed by Todd Shipyards concerning the ability of the LOFT CRDMs to withstand a dry scram is presented. A ''dry scram'' could result in the CRDM components yielding; however, it would probably not render the CRDMs inoperable. It also concluded that a dry scram is highly unlikely based on a typical LOFT depressurization curve and the temperature of the fluid in the upper pressure housing. At the time of scram, the fluid in the upper pressure housing will not flash to steam owing… more

Fabrication of uranium carbide/beryllium carbide/graphite experimental-fuel-element specimens

Description: A method has been developed for fabricating uranium carbide/beryllium carbide/graphite fuel-element specimens for reactor-core-meltdown studies. The method involves milling and blending the raw materials and densifying the resulting blend by conventional graphite-die hot-pressing techniques. It can be used to fabricate specimens with good physical integrity and material dispersion, with densities of greater than 90% of the theoretical density, and with a uranium carbide particle size of less th… more

Technical Specification Figure 3-1, PCS temperature vs. pressure

Description: The bases and procedure for plotting LOFT Technical Specification Figure 3-1, PCS Temperature vs. Pressure is presented. The curves define fracture toughness limits for the carbon steel vessels (Reactor vessel, pressurizer and steam generator) in the primary coolant system (PCS). An allowance is included for the lag between measured fluid temperature and metal temperature of the carbon steel components for the heat up situation. As a result the curves are conservative for the cooldown situation… more

LOFT reactor vessel 290/sup 0/ downcomer stalk instrument penetration flange stress analysis

Description: The LOFT Reactor Vessel 290/sup 0/ Downcomer Stalk Instrument Penetration Flange Stress Analysis has been completed using normal operational and blowdown loading. A linear elastic analysis was completed using simplified hand analysis techniques. The analysis was in accordance with the 1977 ASME Boiler and Pressure Vessel Code, Section III, for a Class 1 component. Loading included internal pressure, bolt preload, and thermal gradients due to normal operating and blowdown.

Dynamic analysis of LOFT reactor flow skirt/core filler assembly for LOCA + SSE

Description: A detailed dynamic analysis of the LOFT reactor core support structures was performed to determine the ability of the flow skirt/core filler and hold-down springs to withstand Loss-of-Coolant Accident (LOCA) plus Safe Shutdown Earthquake (SSE) loadings. A double-ended offset shear occurring in 15 msec (5 msec break time + msec for offset to occur) in the intact loop at the reactor vessel nozzle provided the basis for LOCA loads. The flow skirt/core filler and lower core support structure separa… more

Preliminary study of cross-field plasma injection in 2XIIB

Description: Preliminary results are presented of a study of cross-field plasma injection in the 2XIIB mirror machine. Plasma accelerated by a coaxial deflagration gun was observed to pass 3.5M across the vacuum field, and some trapping was observed when the gun plasma intersected a plasma streaming along B at the center of the magnetic well. Parameters for the experiment are: gun plasma kinetic energy 50 to 200 eV, n/sub gun/ = 3 x 10/sup 13/ cm/sup -3/, streaming plasma 25 to 50 eV and n/sub streaming/ = … more

Evaluation of EPRI nuclear power division research topics supportive of HTGR technology

Description: For HTGR commercialization studies, an LWR/HTGR Technology Transfer program was devised. Candidate programs were identified out of a total of 208 EPRI NPD (Nuclear Power Division) projects. Of these, 26 project areas presented the highest probability for technology transfer. (DLC)

Processing of poly-Si electrodes for charge-coupled devices

Description: A technique has been developed to fabricate poly-Si electrodes for charge-coupled devices. By controlling the microstructure of a poly-Si film, an anisotropic etchant was selected to provide essentially uniform electrode width dimensions. The electrode widths have only a 6% variation for the majority of the devices over the area of a 2 inch silicon wafer.

Kinetics of the radiation-induced exchange reactions of H/sub 2/, D/sub 2/, and T/sub 2/: a review

Description: Mixtures of H/sub 2/--T/sub 2/ or D/sub 2/--T/sub 2/ will exchange to produce HT or DT due to catalysis by the tritium ..beta.. particle. The kinetics of the reaction D/sub 2/ + T/sub 2/ = 2DT may play an important role in designing liquid or solid targets of D/sub 2/--DT--T/sub 2/ for implosion fusion, and distillation schemes for tritium cleanup systems in fusion reactors. Accordingly, we have critically reviewed the literature for information on the kinetics and mechanism of radiation-induce… more

Heat exchanger method: ingot casting; fixed abrasive method: multi-wire slicing (Phase II). Silicon sheet growth development for the Large Area Silicon Sheet Task of the Low Cost Silicon Solar Array Project. Quarterly progress report No. 1, November 21, 1977--December 31, 1977

Description: A high degree of crystallinity has been achieved in ingots cast. Since most of the growth took place near the solidification temperature, the top portion of the ingot was solidified by freezing from the surface. The thickness of this layer was reduced with the control of thermal flow characteristics in the furnace. The crucibles used in this study have a nonuniform bottom which is not conducive to proper heat transfer during solidification. In an effort to achieve high packing density of solar … more

Comparative biogeochemical behaviors of iron-55 and stable iron in the marine environment

Description: Studies of atmospheric aerosols have demonstrated that much of the /sup 55/Fe associated with the aerosol input to the oceans is present as either an amorphous or hydrous iron oxide or as very small particulate species attached to the surfaces of the large aerosol particles. By comparison, nearly all of the stable iron is bound in the mineral phase of aerosol particles. This difference in the chemical and physical forms of the radioactive and stable iron isotopes results in the /sup 55/Fe being… more

Volume reduction system for solid and liquid TRU waste from the nuclear fuel cycle: July--September 1977

Description: Laboratory equipment is being assembled for the investigation of unusual particulate and gaseous radioactive material in the incinerator offgas when commercial wastes are incinerated. This equipment will constitute a bench-scale incinerator system with monitoring equipment to effect the investigation. A literature search was made to determine the current technology used in removing the expected effluents from gas streams. A series of controlled-feed incinerator runs was performed to determine t… more

Distribution of calcretes and gypcretes in southwestern United States and their uranium favorability, based on a study of deposits in Western Australia and South West Africa (Namibia)

Description: Calcrete, dolocrete, and gypcrete carnotite are abundant in western Australia and Namib Desert, although only a few are of ore grade. The geology of these deposits are described. A genetic classification of calcretes emphasizing uranium favorability was developed, based on the distinction between pedogenic and nonpedogenic processes. Similarities between western Australia and South West Africa give support for the conclusions that lateral transport of U in groundwater is essential to ore deposi… more
