BWR containment failure analysis during degraded-core accidents

Description: This paper presents a containment failure mode analysis during a spectrum of postulated degraded core accident sequences in a typical 1000-MW(e) boiling water reactor (BWR) with a Mark-I wetwell containment. Overtemperature failure of containment electric penetration assemblies (CEPAs) has been found to be the major failure mode during such accidents.

Dynamic response of a thin disk subjected to a thermal pulse

Description: The dynamic response of a thin steel disk to a transient thermal pulse induced by a pulsed neodymium-glass laser was studied experimentally and compared with numerical results from a finite element code. The experiment was designed to provide data for use in code development work for erosion/corrosion studies.

Health Insurance: The Pro-Competition Proposals

Description: For more than a decade, Congress and the Executive Branch have tried to stem spiraling health care costs through various regulatory actions at the Federal and State levels. Planning laws, for example, focus regulatory attention on the capacity of the health care industry to provide health services. Other laws have created programs to monitor and control the use of services provided to individual patients. Direct wage and price controls were applied to the health industry in the early 1970's and… more

Influence of centering forces on IFR hose instability

Description: The appropriate centering force terms are added to the ion-focused regime hose equations and their effect on hose development is calculated. It is found that while hose at very high frequencies is stabilized, the overall suppression is only moderate and other stabilization processes need to be explored.

MFTF-B performance calculations

Description: In this report we document the operating scenario models and calculations as they exist and comment on those aspects of the models where performance is sensitive to the assumptions that are made. We also focus on areas where improvements need to be made in the mathematical descriptions of phenomena, work which is in progress. To illustrate the process of calculating performance, and to be very specific in our documentation, part 2 of this report contains the complete equations and sequence of c… more

Negative-potential operation of TMX-Upgrade

Description: A tandem-mirror configuration can be created by combining hot electron end-cell plasmas with neutral-beam pumping. A region of large negative potential formed in each end cell confines electrons in the central cell. The requirement of charge neutrality causes the central-cell potential to become negative with respect to ground in order to equate ion loss to electron loss. Start-up and formation of the axial potential distribution, neutral-beam pumping, hot electron feed, electron-cyclotron-reso… more

Radioisotopes for heat-source applications

Description: Potential DOD requirements for noninterruptable power sources could total 1 MW thermal by FY 1990. Of the three isotopes considered, (/sup 90/Sr, /sup 147/Pm, /sup 238/Pu) /sup 90/Sr is the only one available in sufficient amounts to meet this requirement. To meet the DOD FY 1990 requirements, it would be necessary to undertake /sup 90/Sr recovery operations from spent fuel reprocessing at SRP, Hanford, and the Barnwell Nuclear Fuels Plant (BNFP). /sup 90/Sr recovery from the existing alkaline … more

Sources of hot electrons in laser-plasma interaction with emphasis on Raman and turbulence absorption

Description: Heating targets with high power lasers results in a sizable fraction of the absorbed energy going into electrons of temperature much greater than thermal which can pre-heat the pellet core and accelerate fast ion blowoff which results in poor momentum transfer and hence poor compression efficiency. The present emphasis is to build lasers of higher frequency, ..omega../sub 0/, which at the same W/cm/sup 2/ results in more absorption into cooler electrons. Two physical reasons are that the laser … more

Theory of the optimal design of straight-axis minimum-B mirror confinement configurations

Description: The design of modern straight-axis linked-mirror plasma-confinement configurations involves a balance between many competing requirements. The dipole and quadrupole components of magnetic induction required in one confinement region often do not match onto the fields of an adjacent region without complications that seriously affect particle drifts or confinement stability. Here, the relevant factors are set down together with the techniques for analytical optimization of the design of a general… more
