STATISTICAL ANALYSIS AND MODELING OF GAP CONDUCTANCE DATA FOR REACTOR FUEL RODS CONTAINING UO2 PELLETS

Description: The purpose of this study was threefold: To examine a large body of in-reactor data for UO{sub 2} pellet fuel where internal temperatures have been measured, and to estimate fuel surface temperature, cladding inner temperature, and thus gap conductance under a consistent set of assumptions. To estimate the variance (due to experimental uncertainties) in the inferred gap conductance values. To attempt a correlation of the gap conductance values with design parameters and operating conditions (e.g., with cold diametral gap and local linear power).

Effect of radiation on proteins and radiation effects in biochemistry and organic chemistry. Final report, October 15, 1957--October 14, 1974

Description: A summary is made of a fifteen year study of chemical effects of radiation of amino acids and proteins. Included is a list of publications: 54 papers, reports and abstracts, and 10 M.S. and Ph.D theses. The report concludes with details of the final two studies done under this contract. These are, first, a study of post-irradiation effects of various gases on gamma irradiated lysozyme. This study showed that H$sub 2$S, O$sub 2$, NO, and N$sub 2$O treatment changed the amount of aggregation products, and also that a certain amount of the irradiated lysozyme was subject to main chain cleavage. The second was a study of proteins in rabbit eye lens cataracts induced by x-irradiation or a high galactose diet. The cataract proteins were more soluble in water than normal proteins, and were present in lower amounts in the eye lens. (auth)

Feasibility studies of an accelerator for the intense pulsed neutron source (IPNS)

Description: A proton linac plus synchrotron system was studied for the proposed Intense Pulsed Neutron Source (IPNS) at Argonne. An Alvarez H$sup -$ linac of 70 MeV and a high intensity fast cycling proton synchrotron to accelerate protons to 800 MeV will be the best choice to give a flux of 10$sup 16$ thermal neutron/sec cm$sup 2$ at the surface of moderator with a spallation neutron target of W or $sup 238$U.

Proposal for computer investigation of LMFBR core meltdown accidents

Description: The environmental consequences of an LMFBR accident involving breach of containment are so severe that such accidents must not be allowed to happen. Present methods for analyzing hypothetical core disruptive accidents like a loss of flow with failure to scram cannot show conclusively that such accidents do not lead to a rupture of the pressure vessel. A major deficiency of present methods is their inability to follow large motions of a molten LMFBR core. Such motions may lead to a secondary supercritical configuration with a subsequent energy release that is sufficient to rupture the pressure vessel. The Los Alamos Scientific Laboratory proposes to develop a computer program for describing the dynamics of hypothetical accidents. This computer program will utilize implicit Eulerian fluid dynamics methods coupled with a time-dependent transport theory description of the neutronic behavior. This program will be capable of following core motions until a stable coolable configuration is reached. Survey calculations of reactor accidents with a variety of initiating events will be performed for reactors under current design to assess the safety of such reactors. (auth)

Program Geothm: A thermodynamic process program for geothermal power plant cycles

Description: Program GEOTHM is a thermodynamic process program now under development for the LBL Geothermal Energy Program. To date, the program development has centered upon the modeling of working fluid properties, developing thermodynamic process models, and modeling the design performance of geothermal power plants. When the program is completed, it will be able to optimize a power plant or refrigeration plant for minimum cost power or refrigeration. Furthermore, operation of the thermodynamic cycles at off design conditions will be able to be simulated. Program GEOTHM is currently able to calculate several types of geothermal power cycles using a wide variety of working fluids.

Evaluation of the ERC virtual impactor

Description: Measurements have been made on a dichotomous virtual impactor developed by the Environmental Research Corporation. The object was to study the feasibility of employing the virtual impaction scheme in air samplers to collect size fractionated particle samples for subsequent x-ray fluorescence analysis. The size separation characteristics and losses as a function of particle size at specific locations within the apparatus were determined. It was found that except for the intrinsic losses near the size cut point, most of the losses can be significantiy reduced with improved design. The prospect of large scale deployment of virtual impactors for continuous air monitoring is favorable. (auth)

Infrared spectrum of curium-244

Description: The spectrum of curium-244 has been observed on the high resolution Fourier-transform spectrometer at Laboratoire Aime Cotton. An electrodeless lamp containing 50 $mu$g of CmI$sub 3$ was run for 12 hours and 800,000 points were taken. A total of 1743 lines have been ascribed to curium and 87 percent of the lines have been assigned to transitions between known energy levels.
