Magnetic fusion energy annual report, July 1975--September 1976

Description: Supporting research activities continued to provide the technical basis for future mirror-confinement experiments. The industrial development of a high-current, high-field, high-current-density Nb/sub 3/Sn conductor was the main goal of the superconducting magnet program. Beam direct conversion was being developed as a means of raising the efficiency of neutral-beam production, and plasma direct conversion was shown to work as predicted. Conceptual designs were completed for various types of po… more

LIL8/V2: a list interpretive language for the MCS-8 microcomputer

Description: A list interpretive language designed for microcomputer-based programmable control systems is described. The purpose of this project was to create an easily understood method for scientific personnel (with minimal programming background) to program an MCS-8 microcomputer-controlled chemistry system, via teletype. The intent is for the language to compete in simplicity of understanding with a rotating cam programmer. Also needed was an interrupt capability, a special instruction set, and the abi… more

Tritium-related materials problems in fusion reactors

Description: Pressing materials problems that must be solved before tritium can be used to produce energy economically in fusion reactors are discussed. The following topics are discussed: (1) breeding tritium, (2) recovering bred tritium, (3) containing tritium, (4) fuel recycling, and (5) laser-fusion fueling. (MOW)

Survey of supression of sodium fires in liquid metal fast breeder reactors

Description: A survey was made of protection and suppression technologies relative to liquid sodium fires at selected sites. These technologies will find application in the Liquid Metal Fast Breeder Reactor (LMFBR) program. Based on this survey, a series of conclusions and recommendations are given. Dry type powder agents will only be of use of relatively small sodium fires. Large fires will be extinguished by inerting the chamber or collecting pans where the sodium leak occurs. Liquid sodium fire suppressi… more

Monte Carlo model for a thick target T(D,n)/sup 4/ He neutron source

Description: A brief description is given of a calculational model developed to simulate a T(D,n)/sup 4/ He neutron source which is anisotropic in energy and intensity. The model also provides a means for including the time dependency of the neutron source. Although the model has been applied specifically to the Lawrence Livermore Laboratory ICT accelerator, the technique is general and can be applied to any similar neutron source.

Floating substrate process. First quarterly progress report, January 6, 1976--March 28, 1976

Description: Laboratory apparatus has been designed, built, and put into operation to study the supercooling of Sn--Si melts and the uptake of silicon from silanes. Values of supercooling of Sn--Si melts as high as 78/sup 0/C at 1100/sup 0/C and 39/sup 0/C at 1200/sup 0/C have been observed. Results to date have been limited by nucleation caused by foreign material floating on the surface of the melt. Spontaneously nucleated planar platelet growth has been observed at the Sn--Si supercooled surface having g… more

User's guide to the LLL basic interpretere

Description: Scientists are finding increased applications for microprocessors as process controllers in their experiments. However, while microprocessors are small and inexpensive, they are difficult to program in machine or assembly language. A high-level language is needed to enable scientists to develop their own microprocessor programs for their experiments on location. Recognizing this need, LLL contracted to have such a language developed. This report describes the result -- the LLL BASIC interpreter… more

LPTR irradiation of LLL metglas samples

Description: Irradiation of MetGlas samples in position E-1 of the reactor core is described. Data are tabulated on neutron energy and flux, and irradiation time. Data are also included on a specimen of 304 stainless steel cut from the irradiation assembly liner to be used for dosimetry. (JRD)

Transient analysis Brayton Isotope Power System supplement I

Description: The purpose of this study was to obtain a simulation of the most rapid start-up thermal transient which would be encountered in the BIPS operation. As an aid in reducing the severity of the transient, it was agreed with the NASA that the case to examine would be determined by the following logic: (a) determine the lowest temperature at which a start could be accomplished using a 2 HSA configuration; and (b) define the transients for a 3 HSA start which was initiated when the heat source achieve… more

Temperature-profile determination using frequency-domain reflectometry

Description: The temperature distribution along a coaxial electrical cable can be determined by means of frequency-domain reflectometry if the cable has an inner sheath of a suitable temperature-sensitive dielectric material. Such a technique would have advantages in cost and convenience over the conventional method of placing a separate thermocouple at each point where the temperature is to be measured. It would be especially useful for underground applications in assessing geothermal reservoirs and in ins… more

Nuclear safeguards progress report, July--December 1975

Description: The gamma-ray energy region from 120 to 350 keV was investigated using a 1-cc planar Ge(Li) detector. Plutonium isotopic ratios are presented for 0.25 g NBS Standard Reference Material. The results show the feasibility of obtaining /sup 240/Pu and /sup 241/Am isotopic ratios to better than 5 percent of the chemical value by using gamma-ray spectrometers having 600-eV resolution at 122 keV. A single exponential equation has been used to predict the equilibrium of a 1-in. x 3-in. calorimeter (Mou… more

Neutron activation analysis at the Livermore pool-type reactor for the environmental research program. [Identification of trace element contaminants]

Description: Instrumental neutron activation analysis is a technique of trace analysis using measurements of radioactivity induced in the sample by exposure to a source of neutrons. The induced activity is measured by the emitted gamma radiation. Each gamma emitter can then be identified by the energy of the photopeaks produced as the nuclide decays and by the half-life of the neutron-induced activity. A complex computer program GAMANAL has been used to accomplish the major tasks of nuclide identification a… more
