This Corrective Action Report (CAR) for the Mixed Waste Management Facility (MWMF) is being prepared to comply with the Resource Conservation and Recovery Act (RCRA) Permit Number SC1 890 008 989, dated October 31, 1999. This CAR compiles and presents all groundwater sampling and monitoring activities that are conducted at the MWMF. As set forth in previous agreements with South Carolina Department of Health and Environmental Control (SCDHEC), all groundwater associated with the Burial Ground Complex (BGC) (comprised of the MWMF, Low-Level Radioactive Waste Disposal Facility, and Old Radioactive Waste Burial Ground) will be addressed under this RCRA Permit. This CAR is the first to be written for the MWMF and presents monitoring activities and results as an outcome of Interim Status and limited Permitted Status activities. All 1999 groundwater monitoring activities were conducted while the MWMF was operated during Interim Status. Changes to the groundwater monitoring program were made upon receipt of the RCRA Permit, where feasible. During 1999, 152 single-screened and six multi-screened groundwater monitoring wells at the BGC monitored groundwater quality in the uppermost aquifer as required by the South Carolina Hazardous Waste Management Regulations (SCHWMR), settlement agreements 87-52-SW and 91-51-SW, and RCRA Permit SC1 890 008 …

Correspondence issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO followed up on its previous report on the scope and limits of the Temporary Assistance for Needy Families (TANF) program's 1998 sanction data, focusing on: (1) whether the number of full-family sanctions in an average month in 1998 can be annualized and used to determine the impact full-family sanctions had that year on caseload size; and (2) what constitutes the combined number of full-family and partial sanctions in an average month during 1998."

The requirements for the performance of radiological design reviews are codified in 10CFR835, Occupational Radiation Protection. The basic requirements for the performance of ALARA design reviews are presented in the Hanford Site Radiological Control Manual (HSRCM). The HSRCM has established trigger levels requiring radiological reviews of non-routine or complex work activities. These requirements are implemented in site procedures HNF-PRO-1622 and 1623. HNF-PRO-1622 Radiological Design Review Process requires that ''radiological design reviews [be performed] of new facilities and equipment and modifications of existing facilities and equipment''. In addition, HNF-PRO-1623 Radiological Work Planning Process requires a formal ALARA Review for planned activities that are estimated to exceed 1 person-rem total Dose Equivalent (DE). The purpose of this review is to validate that the original design for the PFP Cementation Process ensures that the principles of ALARA (As Low As Reasonably Achievable) were included in the original project design. That is, that the design and operation of existing Cementation Process equipment and processes allows for the minimization of personnel exposure in its operation, maintenance and decommissioning and that the generation of radioactive waste is kept to a minimum.

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO examined the readiness of the Army National Guard's Enhanced Brigades, focusing on: (1) whether the brigades are meeting training and personnel readiness goals; (2) the key reasons for any continuing difficulties in meeting these goals; and (3) whether the Army has an effective system for assessing brigade readiness and the time required for the brigades to be ready for war."

The Conclusions/Recommendations of this paper are: (1) It is very important to keep the orbit close to the reference orbit. (2) It is likely that BPMs are not perfectly calibrated. (3) The orbit length calculation with Quad Steering ON is more sensitive to errors in the BPM readout than with Quad Steering OFF. However, unless we are at the {psi}{prime}, Quad Steering should be ON. (4) Question: Should we use the BPM corrections derived from this scan? Answer: I don't know. I would prefer not to. If we keep the orbit close to the reference, we don't need the corrections. For cases where the orbit differs appreciably from the reference orbit, we should do the energy calculation both ways. (Perhaps with Quad steering ON and OFF too). (5) We should use the reference orbit derived from this scan. However, if there is the time and the man power, it would be desireable to do a proper scan of the {psi}{prime}.

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the National Marine Fisheries Service's (NMFS) fisheries buyback programs, focusing on: (1) the extent to which the buyback programs have affected fishing capacity; (2) potential ways the buyback programs can be made more effective; and (3) NMFS' efforts to evaluate the effectiveness of buyback programs."

Over the next seven years, at least 5,000 new schools will be designed and constructed to meet the needs of American students in kindergarten through grade 12. National efforts are underway to encourage the use of daylighting, energy efficiency, and renewable energy technologies in school designs, which can significantly enhance the learning environment. Recent rigorous statistical studies, involving 21,000 students in three states, reveal that students perform better in daylit classrooms and indicate the health benefits of daylighting. This paper discusses the evidence regarding daylighting and student performance and development, and presents four case studies of schools that have cost effectively implemented daylighting into their buildings.

Quantitative measurements of the diffusion of adsorbed mixed Ge-Si dimers on the Si(100) surface have been made as a function of temperature using atom-tracking scanning tunneling microscopy. These mixed dimers are distinguishable from pure Si-Si dimers by their characteristic kinetics--a 180-degree rotation between two highly buckled configurations. At temperatures at which the mixed dimers diffuse, atomic-exchange events occur, in which the Ge atom in the adsorbed dimer exchanges with a substrate Si atom. Re-exchange can also occur when the diffusing Si-Si dimer revisits the original site of exchange.

Correspondence issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO responded to congressional questions on its April 6, 2000, testimony on the Bureau of Prisons (BOP) efforts to contain the costs of providing health care to inmates, focusing on whether: (1) requiring a copayment would reduce the number of prisoners seeking medical care in order to get out of work or other duties; (2) recent BOP initiatives have helped reduce staff costs; (3) it would be more cost-effective for BOP to have an intermediate care medical facility for inmates needing long-term care; and (4) the Federal Prisoner Health Care Copayment Act of 1999 would significantly contribute to reducing health care costs."

Correspondence issued by the General Accounting Office with an abstract that begins "Pursuant to a legislative requirement, GAO provided information on the results of the Internal Revenue Service's (IRS) financial statements and on the effectiveness of its internal controls for fiscal year (FY) ending September 30, 1999."

To design more radiation tolerant Integrated Circuits (ICs), it is essential to create and test accurate models of ionizing radiation induced charge collection dynamics within microcircuits. A new technique, Diffusion Time Resolved Ion Beam Induced Charge Collection (DTRIBICC), is proposed to measure the average arrival time of the diffused charge at the junction. Specially designed stripe-like junctions were experimentally studied using a 12 MeV carbon microbeam with a spot size of 1 {micro}m. The relative arrival time of ion-generated charge is measured along with the charge collection using a multiple parameter data acquisition system. The results show the importance of the diffused charge collection by junctions, which is especially significant in accounting for Multiple Bit Upset (MBUs) in digital devices.

A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the Fish and Wildlife Service's (FWS) national fish hatcheries, focusing on whether: (1) the activities carried out at the national fish hatcheries are consistent with their statutory authorizations; and (2) changes in existing laws would be appropriate to provide better direction to FWS on which programs to emphasize and to authorize FWS to make changes in how it manages the hatcheries."

The CY1999 Site Environmental Report and Compliance Summary discusses environmental compliance activities for NPR-3 (Teapot Dome). All hazardous wastes that were stored in the hazardous waste accumulation at NPR-3 were removed in CY1999. NPR-3 maintains its status as a conditionally exempt small quantity generator. Hydrogen sulfide (H2S) flares have not operated at NPR-3 since 1996; monitoring of H2S indicates readings well below limits. All underground storage tanks were removed in 1998. Wastewater samples were in compliance with applicable standards.

The elastic-plastic response of a large-tow 0{sup o}/{+-}{theta}{sup o} tri-axially braided composite is numerically simulated to determine the elastic coefficients and post-yield behavior. The ratios of extensional to flexural effective Young's moduli vary from 0.30 to 0.52 in the longitudinal direction and 0.90 to 0.95 in the transverse direction. Measurements on a 2-ply 0{sup o}/{+-} 30{sup o} braid support these numerical trends. The onset of macro yield in uniaxial extension coincides with the experimental values in the longitudinal direction while it is nearly twice the experimental values in the transverse direction. In simple shear, matrix plasticity around the undulations facilitates local rotation of the braiders at the onset of macro yield. Under uniaxial flexure, modest stiffening occurs prior to strain softening in both the principal directions.

Electrode gap is a very important parameter for the safe and successful control of vacuum arc remelting (VAR), a process used extensively throughout the specialty metals industry for the production of nickel base alloys and aerospace titanium alloys. Optimal estimation theory has been applied to the problem of estimating electrode gap and a filter has been developed based on a model of the gap dynamics. Taking into account the uncertainty in the process inputs and noise in the measured process variables, the filter provides corrected estimates of electrode gap that have error variances two-to-three orders of magnitude less than estimates based solely on measurements for the sample times of interest. This is demonstrated through simulations and confined by tests on the VAR furnace at Sandia National Laboratories. Furthermore, the estimates are inherently stable against common process disturbances that affect electrode gap measurement and melting rate. This is not only important for preventing (or minimizing) the formation of solidification defects during VAR of nickel base alloys, but of importance for high current processing of titanium alloys where loss of gap control can lead to a catastrophic, explosive failure of the process.

Lake Baikal in Russia, the world's oldest and deepest continental lake lies in south central Siberia, near the border to Mongolia. The lake is 1,643 m deep and has an area of about 46,000 km2. It holds one-fifth of all the terrestrial fresh water on Earth. Lake Baikal occupies the deepest portion of the Baikal Rift Zone. It was formed some 30-45 million years ago. The isolated Lake Baikal ecosystem represents a unique niche in nature based on its historical formation. The microbial diversity present in this environment has not yet been fully harvested or examined for products and processes of commercial interest and value. Thus, the collection of water, soil, and sub-bottom sediment samples was decided to characterize the microbial diversity of the isolated strains and to screen the isolates for their biotechnological value.

Testimony issued by the General Accounting Office with an abstract that begins "GAO discussed issues involving the Social Security Administration's (SSA) process for paying attorneys representing applicants for disability benefits, focusing on three areas of the attorney payment process: (1) the process itself, including the costs of processing the payments; (2) possible changes to the way the user fee is charged; and (3) changes being considered for the attorney fee payment process overall."

This first project, under the auspices of the Arctic Military Environmental Cooperation (AMEC) forum, Project 1.4-1 Solid Radioactive Waste Storage Technologies, successfully demonstrated the feasibility of using a polymer-based coating to seal concrete and steel surfaces from permanent radioactive contamination in an Arctic marine environment. A mobile, self-sufficient spraying device, was developed to specifications provided by the Russian Ministry of Defence Northern Navy and was deployed at the RTP Atomflot site, Murmansk, Russia. Demonstration coatings of Polibrid 705 were applied to concrete surfaces exposed to conditions ranging from indoor pedestrian usage to heavy vehicle passage and container handling in a loading bay. A large steel container was also coated with the polymer, filled with solid radwaste, sealed, and left out of doors and exposed to the full 12 month Arctic weather cycle. The field tests were accompanied by a series of laboratory qualification tests carried out at the research laboratory of ICC Nuclide in St. Petersburg. During the 12-month field tests, the sealant coating showed little sign of degradation except for a few chips and gouge marks on the loading bay surface that were readily repaired. Contamination resulting from radwaste handling was easily removed and the surface was not degraded …
