4 K to 20 K Rotational-Cooling Magnetic Refrigerator Capable of 1-Mw to >1-W Operation

Description: The low-temperature, magnetic entropy of certain single-crystal paramagnetic materials, such as DyPO/sub 4/, changes dramatically as the crystal rotates in a magnetic field. A new magnetic refrigerator design based on the anisotropic nature of such materials is presented. The key advantages of the rotational-cooling concept are (1) a single, rotary motion is required, (2) magnetic field shaping is not a problem because the entire working material is in a constant field, and (3) the refrigerator… more

Acoustic agglomeration of power-plant fly ash. A comprehensive semi-annual progress report

Description: Results obtained during the reporting period are presented. The agglomeration of submicron fly ash particles has been studied as a function of sound pressure level, sound frequency, loading, and exposure time. A second generation model of the agglomeration process is being developed. A high-frequency, high-intensity variable speed siren delivering at least 600 W at frequencies up to 4000 Hz has been developed and tested. Details on the design and operation are presented. The agglomeration chamb… more

Aluminum Fuel Canister Corrosion

Description: On June 26, 1977, it was first reported that aluminum fuel canisters stored in the KE Basin were experiencing corrosion to the extent that canister integrity could be jeopardized should the canister remain in storage for an extended period. In an effort to determine the extent of the corrosion, and to monitor its progress, a fuel canister from the KE Basin was examined on July 6, 1977, February 14, 1978, and on August 23, 1979. Two canisters from the N Basin were examined on February 2, 1978. O… more

Analysis of fission-product effects in a Fast Mixed-Spectrum Reactor concept

Description: The Fast Mixed-Spectrum Reactor (FMSR) concept has been proposed by BNL as a means of alleviating certain nonproliferation concerns relating to civilian nuclear power. This breeder reactor concept has been tailored to operate on natural uranium feed (after initial startup), thus eliminating the need for fuel reprocessing. The fissile material required for criticality is produced, in situ, from the fertile feed material. This process requires that large burnup and fluence levels be achievable, w… more

ANL four-meter calorimeter design and operation manual

Description: The four-meter fuel rod calorimetric system measures the thermal power produced by radioactive decay of fuel rods containing Pu. The Pu mass is related to the measured power through the weighted average of the product of the isotopic decay energies and the decay constants of the Pu isotopes present. U content has no effect since the thermal power produced by the U nuclides is insignificant when compared to Pu. Radiations from Pu are alpha particles and low-energy photons. This calorimeter will … more

Annual emissions and air-quality impacts of an urban area district-heating system: Boston case study

Description: A district-heating system, based on thermal energy from power plants retrofitted to operate in the cogeneration mode, is expected to improve local air quality. This possibility has been examined by comparing the emissions of five major atmospheric pollutants, i.e., particulates, sulfur oxides, carbon monoxide, hydrocarbons, and nitrogen oxides, from the existing heating and electric system in the City of Boston with those from a proposed district heating system. Detailed, spatial distribution o… more

Applicability of Japanese NO/sub x/ control in the US

Description: This report surveys the status of NO/sub x/ control for stationary sources in Japan and analyzes applicability of the technology in the US. The principal control methods used in Japan are combustion modification and catalytic reduction using ammonia as the reducing agent. Noncatalytic reduction with ammonia is used to a limited degree. Wet scrubbing methods have been tested but are so unpromising that the development work has practically stopped. The combustion modification developments are app… more

Asphalt saturation of roofing felt on the felt machine: Phase I. Progress report, October 1978-December 1979

Description: The asphalt roofing industry manufactures approximately 10 million tons of product annually. This requires an estimated 40 trillion Btu's in process heat and 4 million tons of asphalt having a fuel value of 140 trillion Btu's. Energy savings in a number of areas appear possible. As an initial investigation, pilot equipment was installed on a commercial felt machine to determine whether saturation on the felt machine was feasible and whether energy savings would result. Work to date has demonstr… more

Assessment of H/sub 2/S control technologies for geothermal power plants

Description: Techniques for controlling hydrogen sulfide (H/sub 2/S) from geothermal development are analyzed. Several technologies for controlling H/sub 2/S emissions from power plants are examined. The Hydrogen Peroxide Combination System, Stretford System and possibly EIC or Coury upstream controls appear capable of compliance with the emission limitations of 100 grams per hour per gross megawatt in 1980 (and 50 q/hr/(g) MW in 1985 or 1990) at the Geysers Dry stream field in Northern California. Unresolv… more

Assessment of the status of fuel cell/battery vehicle power systems

Description: An assessment of the status of the integrated fuel cell/battery power system concept for electric vehicle propulsion is reported. The fuel cell, operating on hydrogen or methanol (indirectly), acts as a very high capacity energy battery for vehicle sustaining operation, while a special power battery provides over-capacity transient power on demand, being recharged by the fuel cell, e.g., during cruising. A focused literature search and a set of industrial and Government contacts were carried ou… more

Assessment of Two-Filter Technique for Correlating Actinium-227 Concentrations in Soils

Description: Concentrations of actinium-227 in soil samples from waste-disposal sites for uranium procession plants were successfully correlated with radon-219 measurements obtained by the two-filter technique, thus avoiding time-consuming and difficult radiochemical analyses. A flow-through sampling device and procedure were developed which determined actinium levels with a precision of 2 pCi/g +- 50%. Theoretical relations for the production of radon from actinium, the decay of radon, and the decay and di… more

Between-hole acoustic surveying and monitoring of a granitic rock mass

Description: The purpose of this technical note is to present preliminary results of an acoustic monitoring study performed as part of a comprehensive rock mechanic and geophysics research program (Ref.20) associated with large-scale heater tests in an abandoned iron-ore mine in central Sweden. The investigation was performed in a fractured granitic rock mass at a sub-surface depth of 340 m, in a drift adjacent to the original iron-ore mine workings. Acoustic monitoring took place between four empty, dry, v… more

Biological conversion of biomass to methane. Final report, June 1, 1976-January 31, 1980

Description: An experimental methane fermentation system was constructed for the purpose of evaluating the processng requirements and conversion efficiencies associated with production of methane from various organic feed stocks. The fermentation reactors had an operating volume 0.775 m/sup 3/. This permitted operation with an approximate continuous feed of milled organics including beef feedlot manure, corn stover, wheat straw and alfalfa hay. A thermochemical pretreatment was applied to the corn stover an… more

Biological removal of organic constituents in quench water from a slagging, fixed-bed coal-gasification pilot plant

Description: This study is part of an effort to assess the efficiency of activated-sludge treatment for removal of organic constituents from high-Btu coal-gasification pilot-plant quench waters. A sample of raw-gas quench water was obtained from the Grand Forks Energy and Technology Center's pilot plant, which employs the slagging, fixed-bed gasification process. The quench water generated in the processing of Indian Head lignite was pretreated to reduce ammonia and alkalinity, and then diluted and subjecte… more

Biological studies of the US Subseabed Disposal Program

Description: The Subseabed Disposal Program (SDP) of the US is assessing the feasibility of emplacing high level radioactive wastes (HLW) within deep-sea sediments and is developing the means for assessing the feasibility of the disposal practices of other nations. This paper discusses the role and status of biological research in the SDP. Studies of the disposal methods and of the conceived barriers (canister, waste form and sediment) suggest that biological knowledge will be principally needed to address … more
