CALOR is a Monte Carlo program package, written in FORTRAN IV, that is designed to assist experimentalists in evaluating and analyzing different types of calorimeter systems that are used in many high-energy physics experiments to determine the energy and direction of incident hadrons, leptons, and photons. This code package is intended to be used with the code package HETC, which supplies needed information on the transport of hadrons and on the spatial location of the electromagnetic source energy. Input and output for a sample problem are presented. 3 figures, 1 table.

Compressive creep tests were performed on molybenum samples exposed to four different pre-test conditions: (1) annealed; (2) annealed and neutron irradiated at 480/sup 0/C to a fluence of 5 x 10/sup 19/ n cm/sup -2/ (E > 1 MeV); (3) stress-relieved; and (4) stress-relieved and neutron irradiated at reactor ambient temperature to a fluence of 1 x 10/sup 19/ n cm/sup -2/ (E > 1 MeV). The tests were performed in the temperature range of 600 to 900/sup 0/C with an initial applied stress of 176.5 MPa. Both pre- and post-test specimens were examined using electron microscopy and the relationship between substructure and mechanical properties is discussed. Possible controlling mechanisms of deformation are proposed and activation energies for creep are determined.

The fluxes of protons emitted during solar flares since 1956 were evaluated. The depth-versus-activity profiles of /sup 56/Co in several lunar rocks are consistent with the solar-proton fluxes detected by experiments on several satellites. Only about 20% of the solar-proton-induced activities of /sup 22/Na and /sup 55/Fe in lunar rocks from early Apollo missions were produced by protons emitted from the sun during solar cycle 20 (1965--1975). The depth-versus-activity data for these radionuclides in several lunar rocks were used to determine the fluxes of protons during solar cycle 19 (1954--1964). The average proton fluxes for cycle 19 are about five times those for both the last million years and for cycle 20. These solar-proton flux variations correlate with changes in sunspot activity.

A simple method for estimating the solubility of TATB in various solvents is presented. We consider it unlikely that a solvent will be found in which TATB is more soluble than 0.1 percent (w/v). Exceptions are the so-called superacids in which the solubility of TATB exceeds 20 percent (w/v).

Some of the features of the computer program GEOTHM are shown. This program designs and optimizes thermodynamic process cycles. Several examples of geothermal cycle optimization are given. Three dimensional plots generated by the computer show how the optimization process works.

Activities included the preparation of presentations for the NRC review committee. Also, a draft program plan on the Protection of Nuclear Materials for both fixed facilities and in-transit systems was submitted to the NRC. Other activities have focused primarily on the development of evaluation methodologies. These efforts have included the development of a computer graphics implementation of EASI (Estimate of Adversary Sequence Interruption), engagement model developments, ISEM (Insider Safeguards Effectiveness Model) documentation, pathing algorithm improvements, and facility characterization methodology improvements. A large effort has been expended in defining and interfacing with possible contractual support involvements. Areas of these involvements include a generic safeguards data base, fault tree analysis techniques, physical protection modeling, human attribute definitions, neutralization modeling, and safeguards network symbology models.

The LLL developed electronic pressure meter (EPMT) is a portable static-pressure calibration instrument for use with the LLL telemetry transducer system at the Nevada Test Site (NTS). It is significantly more accurate and rugged than the bourdon-tube pressure gauge it replaces, and can be incorporated into a field-use, semi-automatic, pressure calibration system. The process by which a transducer is selected for EPMT use from the inventory of field-service-certified transducers and subjected to an extensive preconditioning and calibration procedure is described. By combining this unusual calibration procedure with a unique, statistically based data-reduction routine, the total uncertainty of the measuring process at each calibration point can be determined with high accuracy.

A recent proposal for reducing the end loss of a linear theta pinch is to produce moving magnetic mirrors at the coil ends. The concept entails the sequential pulsing of an axially arranged series of two-turn coaxial coils. The electrical design of such a system presents some unique problems. Ideally, the individual pulse circuits should be completely independent. This would facilitate the design by eliminating interactive effects. In practice, the circuits must be interconnected through isolating inductors to enable the production of a uniform biasing magnetic field. Moreover, the coils must be located physically close together. This produces strong magnetic coupling between the pulse circuits, which can seriously affect the shape and speed of the inward-moving magnetic-mirror field. Possible systems were modeled for the NET-2 circuit analysis code. The models took account of the inductive coupling between the individual circuits in the model. The results show that an increasing magnetic mirror can be produced provided the radius of the theta pinch is not too great compared to the intercoil spacing. The peristaltic field can be maintained for several cycles in the inner coils. The voltage hold-off requirements on the pulse circuit switches are found to be severe, but not impossible …

A draft Manual of Recommended Practice for Aerosol Sampling and Evaluation was completed and sent to the Energy Research and Development Administration (ERDA) Division of Safety, Standards, and Compliance (DSSC) for review. The results of the Survey of Sampling Techniques for Defining Respirable Concentration and/or Particle Size Characteristics of Aerosols were published as LA-6087. The need for greater standardization of ERDA aerosol sampling techniques was indicated. The Aerosol Training Course was presented in 11 sessions to 85 persons. General elements of good practice were emphasized, and recommendation of specific sampling devices or procedures was avoided. A system for estimating dissolution rates of plutonium aerosols was developed. Studies indicate that plutonium aerosols found in the field have a rapid initial dissolution phase followed by a slower secondary phase. Three methods of particle sizing air samples collected on membrane filters were investigated. The most promising was a scanning electron microscope electron microprobe (SEM-EMp) method. An operating plutonium handling facility was a model for development of techniques to evaluate aerosol surveillance systems performance. Airborne contamination records were studied. The physicochemical properties of a plutonium aerosol existing in the facility were investigated in relation to plutonium handling operations. The techniques developed have indicated some …

ERDA and Marathon Oil Company contracted together for a commercial scale demonstration of enhanced oil recovery by the Maraflood (TM) oil recovery process. This M-1 Project is located within Sections 15, 16, 21 and 22, T6N, R13W, Crawford County, Illinois, encompassing approximately 407 acres of Robinson Sand reservoir developed in the first decade of the century. The area covers portions of several waterfloods developed on 10-acre spacing in the 1950's that were approaching their economic limit. This report describes all M-1 Project facilities, how they were prepared or constructed, their purpose and how they operate: (1) wells (drilling and completion); (2) production facility; (3) injection facility; and (4) various service systems required during project development and/or operation.

A wavelength tunable infrared laser heterodyne spectrometer was taken into the stratosphere as part of the instrumentation package on board the stratospheric scientific research balloon, STRATCOM VI, in order to obtain high-resolution atmospheric absorption spectra of nitric oxide and water vapor by measurement of the attenuation of the solar radiance at approximately 5.24 microns. This report describes the development of this instrument system and the experimentation that characterized its performance.

Spatially resolved profiles of low charge state carbon and aluminum ion impurity radiation from EBT were obtained in the vacuum ultraviolet. The data shows EBT to be remarkably free from impurities. Loss times in the surface plasma are found to be approximately 300 ..mu..sec. Thus about one fourth of the input power supports the surface plasma. The measurement places an upper limit on the C V density in the core plasma which indicates that the core plasma is shielded from the impurities in the surface plasma.
