System model for analysis of the mirror fusion-fission reactor

Description: This report describes a system model for the mirror fusion-fission reactor. In this model we include a reactor description as well as analyses of capital cost and blanket fuel management. In addition, we provide an economic analysis evaluating the cost of producing the two hybrid products, fissile fuel and electricity. We also furnish the results of a limited parametric analysis of the modeled reactor, illustrating the technological and economic implications of varying some important reactor de… more

Improved mutagen-testing systems in mice. Progress report, 1 June 1976--31 August 1977

Description: Results are reported from studies on the production of chromosomal inversion by chemical treatment or irradiation of sperm in mice and to detect inversions by observing high frequencies of first meiotic anaphase bridges of their sons or by using chromosomal banding techniques to detect inverted segments cytologically. For each new inversion, which is either of considerable length or which has particularly useful experimental properties, we will determine its linkage group, mark it genetically, … more

Photon compression in cylinders

Description: It has been shown theoretically that intense microwave radiation is absorbed non-classically by a newly enunciated mechanism when interacting with hydrogen plasma. Fields > 1 Mg, lambda > 1 mm are within this regime. The predicted absorption, approximately P/sub rf/v/sub theta/sup e/, has not yet been experimentally confirmed. The applications of such a coupling are many. If microwave bursts approximately > 5 x 10/sup 14/ watts, 5 ns can be generated, the net generation of power from pellet fus… more

Literature search for ceramic vacuum tubes

Description: The NTIS and Engineering Index files were searched for citations relating to Ceramic and/or Metal Electron Tubes and High Temperature Electronics. A total of 24 citations were found relating directly to ceramic tubes and 24 to high temperature electronics. A search for electron tubes in general was examined for high temperature applications and 39 were obtained. Computer printouts of the abstracts are included in appendices. (MHR)

Brayton Isotope Power System (BIPS) superalloy ground demonstration system (GDS-S) detail design review

Description: The material presented at the GDS-S design review meeting held at Phoenix, Arizona on September 7 and 8, 1977, is reported. This design review was specifically scoped to examine the Hastelloy-X Heat Source Heat Exchanger (HSHX) and the Hastelloy-X bellows. These are new components required to upgrade the Workhorse Loop (WHL) to the GDS configuration. Additional topics covered in support of those items were: reliability; materials; and the WHL-to-GDS conversion sequence.

GENVAR: a general linear computer program for model forecasting and variance analysis. [In LRLTRAN for CDC 7600 computer]

Description: This report describes GENVAR, an interactive computer program which can perform a least-squares fit to the matrix equation ..beta..X = Y, where X is a matrix of observable inputs and Y is a vector of observable outcomes for the input values. The program is controlled by teletypewriter, and is written in LRLTRAN for compilation by CHAT and execution on a CDC 7600. The report describes the way the program operates as well as ways GENVAR can be used to make statistically considered forecasts. Samp… more

Biological effects of static and low-frequency electromagnetic fields: an overview of United States literature

Description: Results are reviewed from a number of studies on the biological effects of static and low frequency electromagnetic fields on animals. Based on a long history of experience with electric fields by the utility industry, it appears that intermittent and repeated exposures to strong 60-Hz electromagnetic fields from present power transmission systems have no obvious adverse effect on the health of man. It has been recognized recently that this belief must be tested by carefully designed and execut… more

Some aspects of the mechanism of bacteriophage function. Final progress report. [Mechanisms of inactivation of bacteriophages by ionizing radiation]

Description: Data are summarized from a ten-year study on the radiobiology of phages. The results showed that: phages are inactivated principally by damage to DNA; DNA damage is of two types, base damage and double-strand breakage; double-strand breakage may be lethal because of interruption within a gene, however in phage systems the damage is more fundamental in that only a single DNA fragment is injected into the host; E. coli phage T4 is relatively resistant to inactivation by x-rays; and the rate of pr… more

Creep deformation and rupture behavior of type 304/308 stainless steel structural weldments

Description: The creep deformation and rupture of type 304/308 stainless steel structural weldments at 593/sup 0/C (1100/sup 0/F) was experimentally investigated to study the comparative behavior of the base metal and weld metal constituents. The tests were conducted in support of ORNL's program to develop high-temperature structural design methods applicable to liquid-metal fast breeder reactor (LMFBR) system components that operate in the creep range. The specimens used were thin-walled, right circular cy… more

Alternatives to underground nuclear power plant siting

Description: The presentation contains the results of a literature review of concepts for augmenting the safety of light-water moderated nuclear power plants as alternatives to underground siting. Two types of alternatives were considered. The first type, consisting of alternatives to LWR power production technology such as the high temperature gas reactors (HTGRs), the liquid-metal fast-breeder reactors (LMFBRs), etc., has been previously discussed. The second type, consisting of alternatives within LWR po… more

Integrated system for production of neutronics and photonics calculational constants. Program LINEAR (Version 77-1): linearize data in the Evaluated Nuclear Data File/Version B (ENDF/B) format

Description: We have written a computer code called LINEAR that both converts evaluated cross sections in the ENDF/B format to linear-linear interpolatable form and thins those sections already in that form. The main advantage of the code is that it eliminates the need for any subsequent code to consider anything but linear-linear data.

Integrated system for production of neutronics and photonics calculational constants. Program SIGMA1 (Version 77-1): Doppler broaden evaluated cross sections in the Evaluated Nuclear Data File/Version B (ENDF/B) format

Description: A code, SIGMA1, has been designed to Doppler broaden evaluated cross sections in the ENDF/B format. The code can only be applied to tabulated data that vary linearly in energy and cross section between tabulated points. This report describes the methods used in the code and serves as a user's guide to the code.

Large area silicon sheet task low-cost silicon solar array project. Fifth quarterly progress report, January 1, 1977--April 1, 1977

Description: The seeded growth furnace with the slotted molybdenum susceptor has been operated during the past quarter. Flat sheets of sapphire were used as the tray, and local cooling at the tin-silicon alloy surface was provided by a symmetric water-cooled jet. The silicon surface growth obtained during the past quarter has been consistently polycrystalline. This poor growth is attributed to impurities in the seeded growth furnace, caused by leakage into the system. Two sources have been identified: deter… more

Description: Results are reported from the radiological analysis of environmental samples collected in the Marshall Islands during 1974 through 1976. Most of the samples were collected on or near the Bikini Atoll and included plants, soil, fish, catchment water, and sediments, with emphasis on local marine and terrestrial food items. Data are presented from ..gamma.. spectral analysis and the content of /sup 90/Sr and transuranic elements in the samples.

Detachable blade configurations for a total flow geothermal turbine

Description: The feasibility of using a simple tee-slot configuration to attach removable titanium turbine buckets to a geothermal turbine disk operating at 600 RPM is considered. A finite element stress analysis was utilized and a possible design configuration with maximum tensile stresses of about 30,000 psi was found. Further reduction in this stress level could be made by optimizing the blade-disk geometry. No consideration was given to dynamic stresses caused by vibration.
