1964 Project Springfield studies. Research Report 2. [Stratospheric-tropospheric exchange of fallout particles and subsequent rainout of radioactive particles by precipitation systems]

Description: The analysis of the data for a storm on April 4, 1964, showed that in spite of all efforts to obtain a dynamically and internally consistent three-dimensional analysis of conventional wind, pressure, and temperature data, there remain ambiguities of 50 to 100 miles in the horizontal location of the boundaries of the stratospheric air. Missing wind data and temperature errors, though not disastrous in routine meteorological analysis, can seriously affect the potential vorticity computations for … more

Analysis of Tritium Releases to the Atmosphere by a Ctr

Description: Removal by atmospheric processes of routinely and accidentally released tritium from a controlled thermonuclear reactor (CTR) was investigated. Based on previous studies, the assumed form of the tritium for this analysis was HTO, or tritiated water vapor. Assuming a CTR operation in Morris, Illinois, surface water and ground-level air concentration values of tritium were computed for three space (or time) scales: local (50 Km of a plant), regional (up to 1000 Km of the plant), and global.

Analytic transport theory solutions for steady sources in pure absorbers

Description: The monoenergetic steady-state integral neutron transport equation is solved analytically for several simple source configurations for pure absorbers. Specifically, the scalar neutron flux, phi(r), is derived for configurations in cartesian geometry representing the point, infinite line, infinite plane, finite line, infinite ribbon, finite ribbon, infinite tube, and finite box sources. Some of these configurations (point, infinite line, and infinite ribbon sources) were investigated previously … more

Application of stress corrosion to geothermal reservoirs

Description: There are several alternative equations which describe slow crack growth by stress corrosion. Presently available data suggest that an alternative form may be preferable to the form which is most often used, but the issue cannot be clearly decided. Presently available stress corrosion data on glasses and ceramics suggest that rocks in a proposed geothermal reservoir will crack readily over long time periods, thus seriously limiting the operation of this type of power source. However, in situ hy… more

Basics of Bayesian reliability estimation from attribute test data

Description: The basic notions of Bayesian reliability estimation from attribute lifetest data are presented in an introductory and expository manner. Both Bayesian point and interval estimates of the probability of surviving the lifetest, the reliability, are discussed. The necessary formulas are simply stated, and examples are given to illustrate their use. In particular, a binomial model in conjunction with a beta prior model is considered. Particular attention is given to the procedure for selecting an … more

Calculational model for condensation of water vapor during an underground nuclear detonation

Description: An empirally derived mathematical model was developed to calculate the pressure and temperature history during condensation of water vapor in an underground-nuclear-explosion cavity. The condensation process is non-isothermal. Use has been made of the Clapeyron-Clausius equation as a basis for development of the model. Analytic fits to the vapor pressure and the latent heat of vaporization for saturated-water vapor, together with an estimated value for the heat-transfer coefficient, have been u… more

Chemical and biological studies on nucleic acids and derivatives. Progress report, October 1, 1974--April 30, 1975

Description: Ultraviolet irradiation of N-hydroxyxanthines in the solid state induces a radical that was assigned as an acyl amidogen radical in which the unpaired electron density is partially delocalized throughout the $pi$-cloud of the purine ring. The radical is reduced in the presence of water. In the presence of methanol this process is also accompanied by some 8-substitution. Photochemical deoxygenation in solution was found to proceed from either the nonionized N- hydroxyl tautomer or the conjugate … more

Chemical burnup determination based on spectrophotometric measurement of total rare earth fission products, uranium, and plutonium

Description: A chemical burnup procedure incorporates the ion-exchange separation of uranium, plutonium, and total rare earth fission products (as the fission monitor) followed by the spectrophotometric determination of each. The separation involves retaining uranyl and plutonyl chloride complexes on a macroporous anion exchange column from 12 M HCl, whereas the rare earths and most fission products pass through. Subsequently, plutonium is eluted with 0.1 M HI-12 M HCl and uranium with 0.1 M HCl. From the i… more

Coarse-mesh rebalance methods compatible with the spherical harmonic fictitious source in neutron transport calculations

Description: The coarse-mesh rebalance method, based on neutron conservation, is used in discrete ordinates neutron transport codes to accelerate convergence of the within-group scattering source. Though very powerful for this application, the method is ineffective in accelerating the iteration on the discrete-ordinates-to- spherical-harmonics fictitious sources used for ray-effect elimination. This is largely because this source makes a minimum contribution to the neutron balance equation. The traditional … more

Comments about proposed D-He$sup 3$ experiments in the TFTR

Description: D-He$sup 3$ experiments to simulate DT burns in TFTR have been proposed by members of the Fusion Studies Center at the University of Illinois. Some basic considerations, involved in planning these experiments, are discussed along with important results to be obtained from such measurements. It is argued that fusion-product orbits, instabilities, and other phenomena can be investigated by D-He$sup 3$ simulation of DT burns, before the TFTR is contaminated by tritium. This approach will allow cha… more

Consequences of sodium bond loss from an LMFBR carbide fuel element

Description: The consequences of sodium bond loss from a uranium-plutonium carbide fuel element during normal steady state operation have been assessed. The elements considered are typical of those currently being irradiated in EBR-II, and include elements with and without shroud tubes. The analysis presented is very conservative in that the many simplifying assumptions required were made to predict worse consequences than would be found in a realistic analysis. Following sodium bond loss, fuel melting occu… more
