The Spent Nuclear Fuel (SNF) Project Engineering Support group cold-tested the Eductor System a 15 horsepower multi-stage centrifugal pump manufactured by the Grunfos Corporation with the housing manufactured and sold with the pump by the Tri-Nuclear Corporation and a 3-inch diameter water jet eductor manufactured by the Fox Valve Corporation. The Eductor System was tested to gather and document information to optimize sludge retrieval operations for use in the 105 K Basins. The cold-testing took place during February 12 through February 29, 1996 in the 305 Cold Test Facility basin located in the 300 area. The pump, utilized in conjunction with the eductor, makes up the core of the Eductor System. The pumping unit consists of a 15 hp stainless steel multi-stage centrifugal Grunfos pump which is seated in a stainless steel fabricated housing. Two baskets or filter elements make up part of the housing on the suction side of the pump. The pump can be used independent of the housing but the housing has two identified purposes. The first use is to stabilize the centrifugal pump and give the pneumatic valves and pump discharge piping a solid platform so the Eductor System can be more easily mobilized within the …

This is the final sample analysis report for tank 241-BX-104 (BX-104), cores 126 and 127. Two segments from each core yielded a total of 11 samples which were analyzed. The data quality objectives (DQOs) applicable to this sampling event were the Safety Screening DQO (Dukelow et al. 1995) and the Organic Safety DQO (Turner et al. 1995). The samples were received, extruded and analyzed at PNNL 325 Analytical Chemistry Laboratory (ACL). The analyses were performed in accordance with the Sample Analysis Plan (Gretsinger 1996) and indicated that the tank is safe with respect to the criteria in the Safety Screening and Organic DQO. Detailed analytical results were described in the analytical laboratory 45-day Report (Attachment 1, WHC-SD-WM-DP-171, REV. 0) and final report (Attachment 2, PNL-BX-104 REV.1) prepared by PNNL, 325 Laboratory. Corrections and/or exceptions to the PNNL final report are provided.

Lending to China from the multilateral development banks (MDBs) increased four-fold between 1985 and 1994, from $1.1 billion to $4.3 billion. China is now the MDBs' largest single borrower country. There is considerable debate today, however, whether the MDBs should continue lending to China. In particular, there is sharp debate whether the World Bank should continue making concessional loans to China.

The analysis described in this report develops the Unit Liter Doses for use in the TWRS FSAR. The Unit Liter Doses provide a practical way to calculate conservative radiological consequences for a variety of potential accidents for the tank farms.

Diamond switches are well suited for use in high temperature electronics. Laboratory feasibility of diamond switching at 1 kV and 18 A was demonstrated. DC blocking voltages up to 1 kV were demonstrated. A 50 {Omega} load line was switched using a diamond switch, with switch on-state resistivity {approx}7 {Omega}-cm. An electron beam, {approx}150 keV energy, {approx}2 {mu}s full width at half maximum was used to control the 5 mm x 5 mm x 100 {mu}m thick diamond switch. The conduction current temporal history mimics that of the electron beam. These data were taken at room temperature.

The transport and diffusion module of the WIND System aqueous emergency response program (STREAM code) was replaced with the EPA WASP5 code. A set of input data was developed to model the transport of pollutants from a release point in K-Area to Savannah, Georgia through Indian Grave Branch, Pen Branch, the SRS swamp, Steel Creek, and the Savannah River. To evaluate the modifications to the STREAM code, data from an accidental release of tritiated water from K-Reactor in 1991 were used for benchmarking. A leak in a heat exchanger allowed a small amount of reactor coolant water to be released to cooling streams onsite, eventually reaching the Savannah River. Measurements of tritium concentration were taken at several downstream locations during the release. The results show that the revised STREAM code overpredicts the peak concentrations by 3 to 15%, which is comparable to the measurement uncertainty (one standard deviation). The revised STREAM code underpredicts the transport times of the concentration peak by 18 to 37%. The discrepancies in the travel time could result from uncertainties in the start of the release. The revised STREAM code performed well in simulating both the timing and the magnitude of the maximum observed tritium concentration. …

This five year project is intended to ensure the availability of well- characterized, high-quality coal samples for public and private coal research. It continues support of the DOE Coal Sample Bank and Database at The Pennsylvania State University. Eleven coal samples will be collected, processed, packaged, and analyzed, and a resulting database will be maintained. These samples and data, as well as 45 samples collected under previous contracts, will be distributed to DOE contractors and others performing coal research. Samples will be chosen to maintain a sample bank of 56 coals representing the major US coal fields and a variety of coal ranks and compositions. In addition to standard analyses, liquefaction tests and organic geochemical analyses will be performed. The samples will be stored to minimize deterioration, and 10 samples will be monitored annually by proximate, sulfur forms, and gaseous oxygen analysis to evaluate their condition. Technical progress is summarized for the following tasks: storage and inventory of samples; monitoring of sample quality; collection and processing of replacement samples; basic characterization of coal samples; liquefaction testing; organic geochemistry (nuclear magnetic resonance spectroscopy); distribution of coal samples to users; data entry; and distribution of data to users.

This report summarizes the results of wildlife surveys performed at Rocky Flats Environmental Technology Site (RFETS) from January through December of 1995 as compared with results from previous years. These surveys were performed as part of a long-term ecological monitoring program conducted under the Natural Resource Protection and Compliance Program (NRPCP). This program is essential in identifying and describing fluctuations of wildlife populations, wildlife habitat use, and changes in species using RFETS. The NRPCP provides support to the Department of Energy (DOE) in its role as Natural Resource Trustee, and provides data essential to accomplishing the goal of preserving the unique ecological values of RFETS in keeping with the Rocky Flats Vision presented in the Rocky Flats Cleanup Agreement Public Comment Draft. Wildlife population densities vary due to natural pressures and human influences, and only long-term monitoring can verify which factors influencing wildlife populations are the consequence of natural fluctuations, and which are due to human influences. The wildlife monitoring described in this report provides qualitative data that give an indication of the ecological health of RFETS. Monitoring numbers, habitat affinities, and apparent health of the wildlife populations makes it possible to evaluate the overall ecological health of the site. …

Existing NO{sub x} control technologies have limitations which may prevent them from successfully achieving commercial, cost effective application in the near future. This project develops a family of novel NO{sub x} control technologies, Second Generation Advanced Reburning (SGAR), which have a potential to achieve 90+% NO{sub x} control at a significantly lower cost than Selective Catalytic Reduction (SCR). Phase I consists of six tasks: Task 1.1, project coordination and reporting deliverables; Task 1.2, kinetics of Na{sub 2}CO{sub 3} reactions with flue gas components; Task 1.3, 0.1 {times} 10{sup 6} Btu/hr optimization studies; Task 1.4, 1.0 {times} 10{sup 6} Btu/hr process development tests; Task 1.5, mechanism development and modeling; and Task 1.6, design methodology and application. This second reporting period included both modeling and experimental activities. Modeling was focused on evaluation of ammonia injection into the reburning zone and on the effect of various additives on promotion of the NO-NH{sub 3} interaction in the reburning zone. First bench scale Controlled Temperature Tower (CTT) experiments have been performed on different variants of the Advanced Returning technology. The tests are continued, and the results will be reduced and reported in the next quarter.
