Continental Shelf Processes Effecting the Oceanography of the South Atlantic Bight. Annual Report, June 1, 1975--May 31, 1976

Description: This completes the first year of the ERDA funded South Atlantic Bight study and much of the activity involved equipment acquisition and historical data analysis. However, in spite of the lack of equipment, we did run a full scale experiment in Onslow Bay in September 1975 and data acquired forms the principal scientific results for the year. Data reports and publications are attached. The accomplishments, scientific and otherwise, are summarized on the next few pages followed by a more lengthy … more

Continental Shelf Processes Effecting the Oceanography of the South Atlantic Bight. Hydrography of Onslow Bay, North Carolina: September 1975 (OBIS II). Progress Report

Description: Over the course of OBIS II, 3-14 September, two intrusion cores were observed. One was apparently trapped nearshore over much of the study period, but as time went on, it either dissipated, moved too far shoreward or moved too far laterally along the shelf to be detected by the existing observational grid. The other (later) intrusion was first detected on 5-7 September and was observed to be moving into the Bay from the southeast over the remainder of the study period. Plots of the horizontal t… more

Present status of mirror stability theory. [Review of 2X and MX programs]

Description: A status report of microinstability as it applies to 2XIIB and MX theory for mirror machines is presented. It is shown that quasilinear computations reproduce many of the parameters observed in the 2XIIB experiment. In regard to large mirror machines, there are presented detailed calculations of the linear theory of the drift cyclotron loss-cone mode, with inhomogeneous geometry and nonlinear diffusive effects. Further, the stability of a mirror machine to the Alfven ion-cyclotron instability i… more

Crust formation and mixing in a gassy two-liquid pool

Description: Molten fuel pools with an overlying layer of steel can be expected to form in various stages of the post-accident heat removal sequence, either on in-vessel or ex-vessel core catchers, or on a concrete or refractory floor beneath the reactor vessel. Since the boiling point of steel is approximately the same as the freezing point of UO/sub 2/, one can expect that a crust of frozen UO/sub 2/ may form at the interface. However, there may be significant bubbling through the interface, either by boi… more

Application of Yerzley mechanical oscillograph to testing of Y3333 cellular silicone (progress report 1). [Density; thickness; resilience; effective dynamic modulus]

Description: The usefulness of the Yerzley mechanical oscillograph in detecting differences among Y3333 cellular silicones was evaluated. Four properties of Y3333 were measured: density, thickness, resilience, and effective dynamic modulus. Test samples came from five lots of standard Y3333 compound and from two lots of experimental Y3333. Tests of the four properties revealed that individual sheets of Y3333 were homogeneous. Since sheets from the same lot differed little in properties, normal process varia… more

Discriminator/time interval meter system evaluation report

Description: The purpose of this report is to discuss the evaluation of a modular prototype Discriminator/Time Interval Meter data acquisition unit as a useful tool in a digital diagnostics system. The characteristics, operation and calibration of each of the hardware components are discussed in some detail. A discussion of the system calibration, operation, and data ingestion and reduction is also given. System test results to date are given and discussed. Finally, recommendations and conclusions concernin… more

Pesticide residue analysis of storm-drain waters, 1975

Description: Runoff-water samples for the first, third, and fourth quarters of 1975 were analyzed for pesticide residues at LLL and independently by the LFE Environmental Analysis Laboratories. For the compounds analyzed, upper limits to possible contamination were placed conservatively at the low parts-per-billion level. In addition, soil samples were also analyzed. Future work will continue to include quarterly sampling and will be broadened in scope to include quantitative analysis of a larger number of … more

Microwave cross section of an ionized channel

Description: Measurements of the microwave cross section of the ionized channel created by an intense electron beam propagating in a high density gas are reported. Following a brief theoretical treatment, experimental values at normal incidence for back scattered, forward scattered, and 90/sup 0/ scattered cross section of the beam are reported at 24 GHz for air and nitrogen at 500 torr pressure.

MAFJ: some simple additions to MAFCO. [Generates magnetic fields resulting from collections of current elements, for CDC 7600 computer]

Description: MAFJ is a revision of the MAFCO code which generates magnetic fields (B) resulting from collections of current elements. In addition to the original MAFCO's capabilities, MAFJ follows field lines through a region of interest and calculates integrals of functions along these lines. It can also generate three-dimensional grids of B. MAFJ runs from eight to 15 times faster than MAFCO, depending on the types of current elements chosen. 2 tables.

Abortion: Legal Control

Description: The U.S. Supreme Court decisions in Roe v. Wade, 410 U.S. 112 (1973), and Doe v. Bolton, 410 U.S. 179, which held generally that a State could no longer prohibit abortions in the first 6 months of pregnancy, caused several House and Senate members to move for an abortion prohibition effectuated by congressional action. To this end, proposed bills and constitutional amendments have been introduced in both Houses. Rather than having settled the abortion question conclusively, the Supreme Court de… more

Electron clearing for the ISA proton beam

Description: The circulating protons in the ISABELLE intersecting storage ring accelerator will collide with the residual gas in the vacuum chamber. The electrons produced will tend to be captured by the potential well of the beam itself and result in a neutralization of the space charge of the beam. A detailed analysis is given of the various mechanisms which can be used to reduce the net degree of beam neutralization. It is concluded that the average neutralization will be about 10/sup -4/ for a residual … more

Stress factors for the deformation systems of zirconium under multiaxial stress

Description: Calculation of the resolved shear stresses (rss) that act on various deformation systems in metals and, in particular, the determination of those systems subjected to the highest rss by a given set of multiaxial stresses is of importance in the study of texture development, yielding and plastic flow. This study examines the geometrical influences of any stress state on the deformation modes of zirconium. One slip mode and three twinning modes, comprising twenty-one deformation systems, are cons… more

Water reuse achieved by zero discharge of aqueous waste

Description: Plans for zero discharge of aqueous waste from ERDA's nuclear weapons plant near Denver are discussed. Two plants - a process waste treatment facility now under construction, and a reverse osmosis desalting plant now under design, will provide total reuse of waste water for boiler feed and cooling tower supply. Seventy million gallons of water per year will be conserved and downstream municipalities will be free of inadvertent pollution hazards.

Molten salt extraction of americium from molten plutonium metal

Description: The chemical basis for molten salt extraction separation of americium from plutonium is presented. The extraction factor relationship is used to quantify this liquid-liquid extraction (molten salt-molten metal) unit operation. The amount of salt required for an optimum process is an order of magnitude lower than the amount used previously in the production operation of the process.
