K Basin Sandfilter Backwash Line Characterization Project and Analytical Results for Campaign 24 (open access)

K Basin Sandfilter Backwash Line Characterization Project and Analytical Results for Campaign 24

Sample 203KWBMF was taken from the K West Sandfilter Backwash Pit on November 4, 1999 and received by 2224 Laboratory on November 4, 1999. Analyses were performed on sample 203KWBMF in accordance with ''Letter of Instruction for K Basins sandfilter Backwash Line Samples'' (LOI) in support of the K Basin Sandfilter Backwash Line Characterization Project.

Meat and Poultry: Improved Oversight and Training Will Strengthen New Food Safety System (open access)

Meat and Poultry: Improved Oversight and Training Will Strengthen New Food Safety System

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a legislative requirement, GAO reviewed the Department of Agriculture's (USDA) efforts to improve the safety of meat and poultry products, focusing on whether: (1) the system adopted by USDA in its regulations is consistent with the seven Hazard Analysis and Critical Control Point (HACCP) principles endorsed by the National Advisory Committee on Microbiological Criteria for Foods; (2) the HACCP training program for USDA inspectors is adequate and science-based; and (3) there is an adequate dispute resolution (appeals) process between plants and USDA under the new HACCP inspection system."

Neutron Yield Measurements via Aluminum Activation (open access)

Neutron Yield Measurements via Aluminum Activation

Neutron activation of aluminum may occur by several neutron capture reactions. Four such reactions are described here: {sup 27}Al + n = {sup 28}Al, {sup 27}Al(n,{alpha}){sup 24}Na, {sup 27}Al(n, 2n){sup 26}Al and {sup 27}Al(n,p){sup 27}Mg. The radioactive nuclei {sup 28}Al, {sup 24}Na, and {sup 27}Mg, which are produced via the {sup 27}Al + n = {sup 28}Al, {sup 27}Al(n,{alpha}){sup 24}Na and {sup 27}Al(n,p){sup 27}Mg neutron reactions, beta decay to excited states of {sup 28}Si, {sup 24}Mg and {sup 27}Al respectively. These excited states then emit gamma rays as the nuclei de-excite to their respective ground states.

Phase IV testing of monosodium titanate adsorption with radioactive waste (open access)

Phase IV testing of monosodium titanate adsorption with radioactive waste

Testing examined the extent and rate of strontium, plutonium, uranium, and neptunium removal from radioactive waste solutions at 4.5M and 7.5M in Na concentration by adsorption onto monosodium titanate (MST) at 0.2 g/L. Results indicate that the extents and rates of strontium, plutonium, and neptunium removal in radioactive waste solutions agree well with those previously measured using simulated waste solutions. Uranium removal in the 7.5M Na radioactive waste solution proved similar to that observed with simulated waste solutions. Uranium removal in the 4.5M Na radioactive waste solution proved lower than expected from previous simulant tests. The authors conclude that MST adsorption data obtained from simulated waste solutions provide reliable predictions for use in facility design and flowsheet modeling studies in the Salt Disposition Alternatives program.

Report on EUVL Mask Substrate Development: Low-Expansion Substrate Finishing II (open access)

Report on EUVL Mask Substrate Development: Low-Expansion Substrate Finishing II

This report is a continuation of our assessment of the finishing of low thermal expansion material wafers obtained through three different commercial pathways. This quarter we have patterned and printed a ULE{reg_sign} wafer (Rodel 1) and saw no difference between its images and those from silicon wafer substrates. This further demonstrated that ULE{reg_sign} can be used as the EUVL mask substrate material. We have also evaluated substrates produced by three vendors: Hoya, General Optics, and Rodel. Consistent with our results reported last quarter, surface roughness of the bare substrates from all three companies does not depend on the position. For Hoya, the wafers it produced had a low roughness than those from last quarter. However, the cleanliness of the wafers needs to be improved. For General Optics, the wafer roughness has increased, and it was only able to deliver one wafer this quarter. General Optics will be replaced by Schott ML next quarter. For Rodel, one of its wafers (Rodel 1) that had been cleaned in-house showed excellent finishing and was selected to be patterned. We also observed that the sleeks on the substrates were smoothed by the ML coating. The other two Rodel wafers (Rodel 2 and Rodel 4) …

Results of an inter-laboratory study of glass formulation for the immobilization of excess plutonium (open access)

Results of an inter-laboratory study of glass formulation for the immobilization of excess plutonium

The primary focus of the current study is to determine allowable loadings of feed streams containing different ratios of plutonium, uranium, and minor components into the LaBS glass and to evaluate thermal stability with respect to the DWPF pour.

Sanitary landfill groundwater monitoring report, Third Quarter 1999 (open access)

Sanitary landfill groundwater monitoring report, Third Quarter 1999

This report contains analytical data for samples taken during Third Quarter 1999 from wells of the LFW series located at the Sanitary Landfill at the Savannah River Site. The data are submitted in reference to the Sanitary Landfill Operating Permit. The report presents monitoring results that equaled or exceeded the Safe Drinking Water Act final Primary Drinking Water Standards or screening levels, established by the U.S. Environmental Protection Agency, the South Carolina final Primary Drinking Water Standard for lead, or the SRS flagging criteria.

Weapons of Mass Destruction - the Terrorist Threat (open access)

Weapons of Mass Destruction - the Terrorist Threat

The possibility of a terrorist attack using nuclear, biological, or chemical weapons is an ongoing debate in the national security policy arena. While terrorist motivations have traditionally been political onesthat would not benefitfrom such an attack, concern is now voiced over a possible trend of inflicting greater numbers of casualties. Terrorists most likely to attempt attacks with weapons of mass destruction (WMD) are extremist religious millenarian groups and small splinter terrorist cells. N

The Weatherization Assistance Program: A Fact Sheet (open access)

The Weatherization Assistance Program: A Fact Sheet

The U.S. Department of Energy's (DOE) Weatherization Assistance PRogram (WAP) is one of the largest energy conservation programs in the nation. The DOE program is implemented in a 50 states, the District of Columbia and Native American Tribes. It weatherizes an average of 70,000 dwellings per year. The program strives to increase the energy efficiency of dwellings occupied by low-income persons in order to reduce their energy consumption and lower their fuel bills. It targets vulnerable groups including the elderly, people with disabilities, and families with children.
