This work originates from a task assignment. This basic data report is for design and fabrication of a canister penetration system for use in these experiments. The basic system was designed and fabricated as a result of a previous task assignment and three associated task plans. The new system, which will be used on canistered waste forms produced during the DWPF Start up Test Program, will be a modification of the previous systems. Hence the seven items identified in the next paragraph have been previously designed, fabricated, and tested but will be required as part of the overall system. The canister penetration system to be designed and fabricated shall consist of (1) a device which can penetrate the canister above the glass line while preventing the mixing of the air within the canister with the air in the environment, (2) a sensor for measuring the relative humidity and dew point of the air within the canister, (3) a sensor for detecting the pressure of the system before penetration and the pressure of the canister and system after penetration, (4) a vacuum system for evacuating the canister penetration system, (5) a connecting port to a mass spectrometer for on line analysis …

The separation of pyrite from coal by flotation is based on exploiting the wettability difference between coal and pyrite. There is evidence that the wettability of coal pyrite changes upon superficial oxidation. Therefore, the oxidation of coal pyrite has been studied under carefully controlled electrochemical conditions. In order to identify the species responsible for the changes in wettability, the surface products formed during oxidation have been identified by means of various surface analysis techniques, including X-ray photoelectron spectroscopy (XPS) and ion scattering spectroscopy (ISS). It has been found that pyrite oxidation creates a sulfur-rich surface along with iron oxides/hydroxides. The ratio between these hydrophobic and hydrophilic species correlates well with the results of the wettability measurements.

We have used pore water gradients and in situ benthic flux chamber measurements to assess the total and down-core variations in the organic carbon remineralization rate. To augment standard pore water extractions, we developed techniques to extract pore water samples at 2mm sampling intervals, greatly improving our assessment of near- surface vertical gradients. In addition, much emphasis was placed on directly measuring the exchange of chemicals between the bottom waters and sediment pore waters via in situ benthic flux chamber incubations. The latter were performed with the MANOP bottom lander, and in later expeditions, the Benthic Experimental chamber Instrument (BECI). Results from these measurements were used to assess the several aspects of seafloor organic matter diagenesis.

The overall objectives of the full-Scale Low-NOx Cell{trademark} Burner (LNCB{trademark}) Retrofit project is to demonstrate the cost-effective reduction of NOx generated by a large, base-loaded (70% capacity factor or greater), coal-fired utility boiler. Specific objectives include: (1) At least 50% NOx reduction over standard two-nozzle cell burners, without degradation of boiler performance or life; (2) acquire and evaluate emission and boiler performance data before and after the retrofit to determine NOx reduction and impact on overall boiler performance; (3) demonstrate that the LNCB{trademark} retrofits are the most cost-effective alternative to emerging, or commercially-available NOx control technology for units equipped with cell burners. The focus of this demonstration is to determine maximum NOx reduction capabilities without adversely impacting plant performance, operation and maintenance.

The focus of this demonstration is to determine maximum NO{sub x} reduction capabilities without adversely impacting plant performance, operation and maintenance. In particular, the prototype evaluations will resolve many technical issues not possible to address fully in the previous pilot-scale work and the single full-scale burner installation.

On December 24, 1991, the K-Reactor was in the shutdown mode with full AC process water flow and full cooling water flow. Safety rod testing was being performed as part of the power ascension testing program. The results of cooling water samples indicated tritium concentrations higher than allowable. Further sampling and testing confirmed a Process Water System to Cooling Water System leak in heat exchanger 4A (HX 4A). The heat exchanger was isolated and the plant shutdown. Heat exchanger 4A was removed from the plant and moved to C-Area prior to performing examinations and diagnostic testing. This included locating and identifying the leaking tube or tubes, eddy current examination of the leaking tube and a number of adjacent tubes, visually inspecting the leaking tube from both the inside as well as the area surrounding the identified tube. The leaking tube was removed and examined metallurgically to determine the failure mechanism. In addition ten other tubes that either exhibited eddy current indications or would represent a baseline condition were removed from heat exchanger 4A for metallurgical examination. Additional analysis and review of heat exchanger leakage history was performed to determine if there are any patterns which can be used for predictive …
