Application of microwave solidification technology to radioactive waste

Description: The EPA has declared vitrification to be the Best Available Demonstrated Technology (BDAT) for High Level Radioactive Waste (40 CFR 268.42). Vitrification has been chosen as the method of choice for treating a number of radioactive residues and wastes in the DOE complex. Vitrification offers advantages of waste volume reduction, the ability to handle changing waste forms, and a stable, nonleachable final waste form. Microwave heating is a superior method for vitrification of radioactive wastes.… more

AXAIR and PUFF-PLUME Comparison

Description: A test version of AXAIR has been prepared to compare with PUFF-PLUME. The test version of AXAIR applies the same meteorological conditions as PUFF-PLUME and also the dispersion coefficients have been changed to be the same as those in PUFF-PLUME. The test version of AXAIR and PUFF-PLUME produce virtually the same doses with the differences being less than 3% for the select cases with similar input. Differences and similarities in the models are also addressed.

Can solid-state laser technology serve usefully beyond fusion ignition facilities?

Description: We have explored the major technical and conceptual issues relating to the suitability of a diode-pumped solid state laser as a driver for an inertial fusion energy power plant. While solid state lasers have long served as the workhorse of inertial confinement fusion physics studies, the deployment of a driver possessing adequate efficiency, reliability, and repetition rate for inertial fusion energy requires the implementation of several technical innovations discussed in this article.

A comparison of the shielding performances of the AT-400A, Model FL and Model AL-R8 containers

Description: A comparison of the neutron and photon dose rates at different locations on the outside surface of the Model AL-RB, Model FL and the AT-400A containers for a given pit load has been done in order to understand the shielding characteristics of these containers. The Model AL-R8 is not certified for transport and is only used for storage of pits, while the Model FL is a certified Type B pit transportation container. The AT-400A is being developed as a type B pit storage and transportation containe… more

Comparison of Tophet-A and Evanohm-R alloys for producing thin film nichrome resistors. Final report

Description: The purported advantages of the Evanohm alloy were not observed in this preliminary study. Under the deposition conditions, the Evanohm alloy produced a greater variation in resistance of the as-deposited thin films than the Tophet alloy currently in use for producing resistors. A broader screening experiment for optimum operating conditions for the Evanohm wire is recommended.

Compositions and Durabilities of Glasses for Immobilization of Plutonium and Uranium

Description: As the nuclear weapon arsenals of the United States and the Former Soviet Union are reduced, metric tonnage quantities of fissile material must be dispositioned. One of the potential disposition options for fissile weapons material is vitrification into a stable form -- essentially a plutonium or uranium single phase glass product. Savannah River Technology Center (SRTC) at Savannah River Site (SRS) is actively developing suitable glass formulations for the long term safe storage of plutonium a… more

Conversion of plutonium scrap and residue to boroilicate glass using the GMODS process

Description: Plutonium scrap and residue represent major national and international concerns because (1) significant environmental, safety, and health (ES&H) problems have been identified with their storage; (2) all plutonium recovered from the black market in Europe has been from this category; (3) storage costs are high; and (4) safeguards are difficult. It is proposed to address these problems by conversion of plutonium scrap and residue to a CRACHIP (CRiticality, Aerosol, and CHemically Inert Plutonium)… more

Cost-Benefit Analysis: Issues in Its Use in Regulation

Description: This report sketches issues underlying broader use of cost-benefit analysis. It focuses on cost-benefit as one of several related frameworks for assessing regulatory actions or policies. Cost-benefit is the broadest of these frameworks, which also include impact assessment, risk assessment, and cost-effectiveness. Which analytical framework is appropriate depends on the regulatory context.

A coupled atmosphere-river flow simulation in California during the 1994-1995 winter

Description: Calculation of river flow is important for managing reservoirs and flood forecasting. In the western United States, a complex terrain which is characterized by steep slopes and narrow valleys often cause a substantial rise of river levels in a short period during heavy precipitation events. Since flood control is one of the major tasks of reservoir operation, inaccurate predictions of precipitation and river flow may cause flooding or waste of water resources. Accurate calculations of river flo… more

D0 Silicon Upgrade: Scaffolding Plateform at Muon Chamber

Description: The design for the scaffolding platform which will be connected to the muon chamber wall was analyzed for a load rating of 400 lbs. The platform is supported on each end and the calculations were done for the full 400 lbs. on the end of the horizontal beam. Both members were analyzed for maximum stresses and were compared to the allowable stress, and both members were found to be acceptable in accordance with the ASCE and AISC specifications. The only recommendation is for all the 3/8-inch stee… more

D0 Silicon Upgrade: Upgrade Piping Loads on Cleanroom Roof

Description: The proposed piping layout for the DO upgrade will run along the south wall of DAB. The cryogenic service pipe runs above the upper and lower cleanroom roofs and will need to be supported by the roofs beams. Calculations were done to determine the stresses in the I-beams created by the existing and additional loads due to the upgrade. Refer to drawing no. 3823.115-ME-317283 for drawings of the piping layout. Figure 1 shows the 'plan view' portion of this drawing. The weight of the individual li… more
