Studies of evaporative and conventional cooling of an energy conserving California house

Description: For cooling a Sacramento, California home, (1) higher thermostat settings, (2) insulation (3) ''solar control'' window shades, and (4) the use of an evaporative cooler in the place of a vapor compression cycle air conditioner are studied. A computer program TWOZONE is used to evaluate the effect on energy consumption and peak power. It is calculated that the peak cooling load can be reduced by a factor of 5 or more and the total energy by a factor of 20 or more.

Determination of performance criteria for high-level solidified nuclear waste from the commercial nuclear fuel cycle: a probabilistic safety analysis

Description: To minimize the radiological risk from the operation of a waste management system for the safe disposal of high-level waste, performance characteristics of the solidified waste form must be specified. The minimum waste form characteristics that must be specified are the radionuclide volatilization fraction, airborne particulate dispersion fraction, and the aqueous dissolution characteristics. The results indicate that the pre-emplacement environs are more limiting in establishing the waste form… more

Neutron - Proton Elastic Scattering from 70-GeV/c to 400-GeV/c

Description: The authors have measured neutron-proton elastic scattering cross sections for four-momentum transfers .17 {le} -t {le} 3.5(GeV/c){sup 2}. The logarithmic slope parameter is found to be consistent with existing proton-proton parameterizations. The data also exhibit a dip in the cross section near -t {approx} 1.4(geV/c){sup 2} for incident neutron momenta above 200 GeV/c. Differences between n-p and p-p cross sections are noted in the region .7 {le} -t {le} 1.4(GeV/c){sup 2}.

Systems analysis study for waste management criteria

Description: LLL is providing technical support to the U.S. NRC in the development of standards for the management and disposal of high-level and transuranic wastes. The problem logically splits into two phases: the pre-emplacement phase of the waste management system and the repository post-sealing phase. Using a system analysis approach, we have structured our modeling effort in such a way as to produce societal risk evaluations at stated confidence levels so that the NRC can develop regulations for the b… more

Relationships between removal processes and residence times for atmospheric pollutants

Description: This report is concerned with improving estimates for the residence times of atmospheric trace constituents in various atmospheric reservoirs. Residence times are defined only for steady-state conditions; i.e., when the net growth rate vanishes. The most useful case of vanishing net growth rate is when the total growth rate is equal to the decay rate. It is demonstrated that the most important advance towards improving estimates of pollutant residence times is through proper choices of reservoi… more

Theoretical interpretation of high-Z discs irradiated with 1. 06. mu. laser light

Description: High Z discs have been irradiated with 1.06 ..mu.. laser light at intensities between 7 x 10/sup 13/ and 3 x 10/sup 15/ W/cm, and pulse lengths between 200 and 1000 ps. Due to the high Z, inverse bremsstrahlung becomes an important absorption effect and competes strongly with resonance absorption and stimulated scattering. We find that inhibited electron thermal conduction and non-LTE ionization physics are important. Their inclusion in the LASNEX modeling results in steepened temperature and d… more

Geochemistry and radionuclide migration

Description: Theoretically, the geochemical barrier can provide a major line of defense in protecting the biosphere from the hazards of nuclear waste. The most likely processes involved are easily identified. Preliminary investigations using computer modeling techniques suggest that retardation is an effective control on radionuclide concentrations. Ion exchange reactions slow radionuclide migration and allow more time for radioactive decay and dispersion. For some radionuclides, solubility alone may limit … more

Preparation of uranium standard solutions for x-ray fluorescence analysis

Description: A method has been developed for gravimetrically preparing uranium nitrate standards with an estimated mean error of 0.1% (1 sigma) and a maximum error of 0.2% (1 sigma) for the total uranium weight. Two source materials, depleted uranium dioxide powder and NBS Standard Reference Material 960 uranium metal, were used to prepare stock solutions. The NBS metal proved to be superior because of the small but inherent uncertainty in the stoichiometry of the uranium oxide. These solutions were used to… more
