Millville Wind Turbine Generator: failure analysis and corrective design modification

Description: Fatigue cracks in the blade skins of the Millville Wind Turbine Generator were fractographically analyzed. It is believed they were caused by large flapwise deflections during a wind storm on December 4, 1978. The deflections caused the skin to buckle, which initiated rapidly growing fatigue cracks. Propagation continued to the leading edge, moving radially inward and outward along the leading edge radius. Communication between Rockwell and Millville resulted in a modified blade design which in… more

Status report on studies to assess the feasibility of storing nuclear waste in Columbia plateau basalts

Description: Basalts, such as the Columbia Plateau basalts, which underlie a large portion of the Pacific Northwest and the Hanford Site, were selected for initial geologic reconnaissance. Geologic exploration of Columbia Plateau basalts was needed to determine the feasibility of utilizing those formations as a site for terminal storage of commercial nuclear waste. The Basalt Waste Isolation Program within Rockwell Hanford Operations has been chartered with the responsibility of conducting these investigati… more

Method of inspecting Raschig rings by neutron absorption counting

Description: A neutron counting method for inspecting borosilicate glass Raschig rings and an apparatus designed specifically for this method are discussed. The neutron count ratios for rings of a given thickness show a linear correlation to the boron oxide content of the rings. The count ratio also has a linear relationship to the thickness of rings of a given boron oxide content. Consequently, the experimentally-determined count ratio and physically-measured thickness of Raschig rings can be used to stati… more

Air quality measurements in the coal-fired power plant environment of Colstrip, Montana

Description: A network of up to six air monitoring and sampling stations were operated 4 to 23 km downwind of the 700 MW coal-fired power plants at Colstrip, Montana. Continuous monitoring identified background SO/sub 2/ levels in the surrounding air at approximately 1 ppB (2.3 ..mu..g/m/sup 3/). Average air concentrations measured in 1978 throughout the network increased to about 2 ppB (4.6 ..mu..g/m/sup 3/) as a result of power plant operations. Meteorological and aerosol correlations with SO/sub 2/ conce… more

Investigation of stick-slip (chatter) phenomenon of HTGR thermal barrier attachment fixture sliding interfaces. Phase I test: Class A thermal barrier hardware and environment

Description: This test program was performed to investigate if significant chatter (stick-slip) would occur at the thermal barrier sliding surfaces. Given such conditions, cyclic loads could be induced in the thermal barrier attachment fixture and studs. A representative section of thermal barrier was tested with realistic HTGR temperature cycles in a high purity helium environment. No significant chatter was detected and there was no visible deterioration of the hardware after testing.

Spent fuel: prediction model development

Description: The need for spent fuel disposal performance modeling stems from a requirement to assess the risks involved with deep geologic disposal of spent fuel, and to support licensing and public acceptance of spent fuel repositories. Through the balanced program of analysis, diagnostic testing, and disposal demonstration tests, highlighted in this presentation, the goal of defining risks and of quantifying fuel performance during long-term disposal can be attained.

High efficiency thin film CdTe solar cells. First quarterly progress report, March 19-June 18, 1979

Description: During the first quarter of this contract, facilities for the high vacuum evaporation of thin film CdTe were prepared. A number of evaporations were performed of both p-type (phosphorus doped) and n-type (halogen doped) CdTe on both conductive and non-conductive substrates. Optical, physical, and electrical evaluations were made. Initial results indicate that the films are predominantly cubic, but that film resistivity is generally still too high and that an anomalous barrier exists at the ITO/… more

The Very deep hole concept: evaluation of an alternative for nuclear waste disposal

Description: One proposal for disposing of radioactive waste is to put it in drill holes or mined cavities so deep that the waste would be effectively isolated from the surface. Even if radioisotopes escaped from the disposal canister, they would be removed from the circulating groundwater system by sorption and/or chemical reaction in their transit on very long paths to the surface. This report summarizes the feasibilities and costs of making deep holes and deep mine shafts; estimates probable technologica… more

Experimental determination of radiation damage function for graphite

Description: Highly oriented pyrolytic-graphite samples were irradiated in three different neutron sources with average energies of 1.5, 5.5, and 14.8 MeV, respectively. The resulting changes in the basal-plane elastic shear moduli of these samples show that the relative damage rate is substantially higher at the higher neutron energies than is predicted by existing models. The results of these experiments have been used to generate a new relative damage function which will allow better projections of graph… more
