Simulated seismic event release fraction data: Progress report, April 1986-April 1987

Description: The object of this project is to obtain experimental data on the release of airborne particles during seismic events involving plutonium handling facilities. In particular, cans containing plutonium oxide powder may be involved and some of the powder may become airborne. No release fraction data for such scenarios are available and risk assessment calculations for such events lacked specificity describing the physical processes involved. This study has provided initial data based on wind tunnel… more

Benzene distribution in product streams from in-tank processing

Description: Benzene is the major product of radiolytic decomposition of tetraphenylborate salts during in-tank salt decontamination. Its production rate has been measured at the Savannah River Laboratory (SR) and at the University of Florida under various conditions of importance to the in-tank process. Recent work has been concerned with the extent of decomposition for long storage periods, and the composition of the product streams from the process. The major results from this work are: the stored potass… more

Role of turgor pressure and solute transport in plant cell growth: Progress report

Description: Plant cell expansion requires coordinationion of three distinct processes: wall relaxation and synthesis, water uptake, and solute uptake. Wall relaxation reduces cell turgor pressure and thereby generates the reduced water for water potential needed uptake. Our studies with pea (Pisum sativum L.) and soybean (Glycine max Merr.) seedlings have shown that water uptake is rapid and is not a major control point for growth. Our current focus is on the processes of wall relaxation and solute transpo… more

Evaluation of the /sup 252/Cf-source-driven neutron noise analysis method for measuring the subcriticality of LWR fuel storage casks

Description: The /sup 252/Cf-source-driven neutron noise analysis method was evaluated to determine if it could be used to measure the subcriticality of storage casks of burnt LWR fuel submerged in fuel storage pools, fully loaded and as they are being loaded. The motivation for this evaluation was that measurements of k/sub eff/ would provide the parameter most directly related to the criticality safety of storage cask configurations of LWR fuel and could allow proper credit for fuel burnup without relianc… more

Review of the state of criticality of the Three Mile Island Unit 2 core and reactor vessel

Description: The events during the early hours of the Three Mile Island Unit 2 (TMI-2) accident on March 28, 1979 caused the fuel in the reactor core to crumble or disintegrate, and then subside into a rubble structure more compact that its normal configuration. The present height of the core is about seven feet, five feet less than its normal configuration of 12 feet. With the same boron content and some or all of the control rod and burnable poison rod material as the normal core configuration, the collap… more

Low loss laser glass: Final report

Description: The objective of this work was a process development on making a laser glass with loss coefficient of 10/sup -4/cm/sup -1/ at 1.05..mu... The key issues for making such a low loss glass will be to use pure raw materials, to reduce OH content and to prevent contamination from the melting environment. A sublimation method was tried to prepare pure P/sub 2/O/sub 5/ batch material. In an attempt to distinguish contributions to the overall loss, glasses were melted in furnaces which were controlled … more

Energy spectra of the pneumatically positioned neutron sources at LLNL's Hazards control standards and calibration facility

Description: The Hazards Control Department of Lawrence Livermore National Laboratory maintains a Standards and Calibration Laboratory that includes three neutron sources (two /sup 252/Cf and one /sup 238/PuBe that can be positioned pneumatically for irradiations. Ten moderators exist to modify the neutron energy spectra produced by these sources. The thicknesses and materials of these moderators are: 25-cm water; 5-, 10-, 15-, and 25-cm heavy water; 20-cm aluminum; and 2-, 5-, 10-, and 15-cm polyethylene. … more

Improvements in apparatus and procedures for using an organic liquid scintillator as a fast-neutron spectrometer for radiation protection applications

Description: For use in radiation protection measurements, a neutron spectrometer must have a wide energy range, good sensitivity, medium resolution, and ease of taking and reducing data. No single spectrometer meets all of these requirements. Several experiments aimed at improving and characterizing the detector response to gamma rays and neutrons were conducted. A light pipe (25 mm) was needed between the scintillator cell and the photomultiplier tube to achieve the best resolution. The light output of th… more

D-Zero Calorimeter Multiplan

Description: This short report explains the parameters, and their basis, of the D-Zero calorimeter multiplan spread sheet Macintosh Multiplan worksheets have been found to be a valuable asset to the D-Zero design effort. The spread sheet contains parameters (constants) and results that come from the parameters. The full effect of changes in D-Zero calorimeter parameters can be calculated quite easily with Multiplan. When a change in a parameter is made, any results that pertain to that parameter automatical… more

Summary of Deflections from Fully Assembled EC Structure Finite Element Model

Description: The purpose of this note is to summarize the deflections in the fully assembled EC OH and MH module arrays as calculated by a superelement finite element model. These results are for the case where the OH modules are fully connected at four locations on the inner radius and four locations on the outer radius. Both the OH and MH modules are modeled as skins and endplates (and in the case of OH, internal structural plates) only. The OH module has a skin thickness of 1/16-in. Fig. 1 shows the full… more

The polarization field for pulsed Raman transitions

Description: This memo discusses the induced polarization field that occurs in the presence of Raman processes, and the propagation equations that result from this field. First the paper summarizes the relationship between the macroscopic polarization field and the microscopic dipole-moment expectation value. It summarizes expressions for the induced dipole moment that result from the adiabatic elimination of non-resonant molecular transitions, to produce an effective two-photon (Raman) Hamiltonian. Then it… more

Alleviation of fuselage form drag using vortex flows: Final report

Description: The concept of using vortex generators to reduce the fuselage form drag of transport aircraft combines the outflow from the plane of symmetry which is induced by the rotational component of the vortex flow with the energization of the boundary layer to reduce the momentum thickness and to delay or eliminate flow separation. This idea was first advanced by the author in 1981. Under a DOE grant, the concept was validated in wind tunnel tests of approximately 1:17 scale models of fuselages of Boei… more
