This document provides a discussion of the development of the FORTRAN Monte Carlo program SCINFUL (for scintillator full response), a program designed to provide a calculated full response anticipated for either an NE-213 (liquid) scintillator or an NE-110 (solid) scintillator. The program may also be used to compute angle-integrated spectra of charged particles (p, d, t, /sup 3/He, and ..cap alpha..) following neutron interactions with /sup 12/C. Extensive comparisons with a variety of experimental data are given. There is generally overall good agreement (<10% differences) of results from SCINFUL calculations with measured detector responses, i.e., N(E/sub r/) vs E/sub r/ where E/sub r/ is the response pulse height, reproduce measured detector responses with an accuracy which, at least partly, depends upon how well the experimental configuration is known. For E/sub n/ < 16 MeV and for E/sub r/ > 15% of the maximum pulse height response, calculated spectra are within +-5% of experiment on the average. For E/sub n/ up to 50 MeV similar good agreement is obtained with experiment for E/sub r/ > 30% of maximum response. For E/sub n/ up to 75 MeV the calculated shape of the response agrees with measurements, but the calculations underpredicts the measured …

Among various two-phase flow regimes, the inverted flow in the post-dryout region is relatively less well understood due to its special heat transfer conditions. The review of existing data indicates further research is needed in the areas of basic hydrodynamics related to liquid core disintegration mechanisms, slug and droplet formations, entrainment, and droplet size distributions. In view of this, the inverted flow is studied in detail both analytically and experimentally. Criteria for initial flow regimes in the post-dryout region are given. Preliminary models for subsequent flow regime transition criteria are derived together with correlations for a mean droplet diameter based on the adiabatic simulation data.

This report documents the results of the Environmental Monitoring Program at the Lawrence Livermore Laboratory (LLNL) for 1987. To evaluate the effect of LLNL operations on the local environment, measurements were made of direct radiation and a variety of radionuclides and chemical pollutants in ambient air, soil, sewage effluents, surface water, groundwater, vegetation, foodstuff, and milk at both the Livermore site and nearby Site 300. Evaluations were made of LLNL's compliance with the applicable guides, standards, and limits for radiological and nonradiological releases to the environment. The data indicates that the only releases in excess of applicable standards were four releases to the sanitary sewer. LLNL operations had no adverse impact on the environment during 1987. 65 refs., 24 figs.

The Working Group on New Particles and Interactions met as a whole at the beginning and at the end of the Workshop. However, much of what was accomplished was done in five subgroups. These were devoted to: (1) new quarks and leptons; (2) technicolor; (3) supersymmetry; (4) rare decays and CP; and (5) substructure of quarks and leptons. Other aspects of new particles, e.g., Higgs, W', Z', fell to the Electroweak Working Group to consider. The central question of this Workshop of comparing anti pp (with L = 10/sup 32//cm/sup 2/-sec) with pp (with L = 10/sup 33//cm/sup 2/-sec) colliders carried through to all these subgroups. In addition there were several other aspects of hadron colliders which were considered: what does an increase in ..sqrt..s gain in cross section and resultant sensitivity to new physics versus an increase in luminosity; will polarized beams or the use of asymmetries be essential in finding new interactions; where and at what level do rate limitations due to triggering or detection systems play a role; and how and where will the detection of particles with short, but detectable, lifetimes be important. 25 references.

Separate abstracts were prepared from six chapters in these workshop proceedings.

Magnetic monopoles captured in the core of the sun may give rise to a substantial flux of energetic neutrinos by catalyzing the decay of solar hydrogen. We discuss the expected neutrino flux in underground detectors under different assumptions about solar interior conditions. Although a monopole flux as low as F/sub M/ /approximately/ 10/sup /minus/24/ cm/sup /minus/2/ sec/sup /minus/1/ sr/sup /minus/1/ could give rise to a neutrino flux above atmospheric background, due to M/bar M/ annihilation, this does not translate into a reliable monopole flux bound stronger than the Parker limit. 8 refs., 1 fig.

The objective of this project is to identify, prepare, test, characterize, and evaluate a practical, homogeneous catalyst for a water-gas shift process. The project effort is divided into the following five tasks: (1) Update SRI's recent review of the literature on the catalysis of the water-gas shift reaction (WGSR) to include references after 1982 and those in the patent literature. Based on this review, SRI will choose ten candidate systems to be evaluated as to their abilities to catalyze the WGSR using syngas derived from gasified coal. (2) Develop a test plan designed to effectively evaluate both the catalysts and, to some extent, reactor configuration for WGSR catalysis. (3) Perform a series of experiments to identify the most effective and economical of the ten candidate catalysts and then further evaluate the reaction kinetics of at least one selected catalyst system to develop sufficient data to provide the basis for the work in Task 4. (4) Develop a mathematical model of the final candidate system that uses rate expressions to describe the catalytic process. (5) Perform a techno-economical evaluation of the catalyst in terms of a proposed plant design based on the reaction model, current costs, and standard chemical engineering practice …

Semileptonic ..lambda../sub c//sup +/ decays have been observed in 29 GeV e/sup +/e/sup /minus/ annihilation. We observe the channels ..lambda../sub c//sup +/ ..-->.. e/sup +/..lambda..X and ..lambda../sub c//sup +/ ..-->.. ..mu mu lambda..X. The production rate for ..lambda../sub c//sup +/, times Br(..lambda../sub c/ ..-->.. l/sup +/..lambda..X) of 0.0031 +- 0.0012 +- 0.0010 per hadronic event for electrons, and 0.0024 +- 0.0007 per hadronic event for muons. When combined with the Lund model prediction for ..lambda../sub c//sup +/ production, this gives semileptonic branching ratios of roughly 5% about what is expected. When combined with the UCLA model prediction for ..lambda../sub c//sup +/ production, this gives semileptonic branching ratios of 17% and 13% for electrons and muons, somewhat higher than expected.

In these lectures, the array of new phenomena are reviewed which might be discovered in electron-positron reactions conducted at energies well above the Z/degree/. Before beginning a discussion of what new phenomena we might find, or how we might uncover them, the question is addressed of why such a program of research is important. The question of what we should be looking for, and what discoveries will be the most illuminating, as we search for the next layer of fundamental physics is argued. With this background, we can then discuss in some considerable detail the contributions that the study of electron-positron collisions at high energy can make in this search.

Resonant, single-photon excitation of ground state inert gases requires light in the vacuum ultraviolet spectral region. This paper discusses methods for generating this light. Efficient schemes for ionizing argon, krypton, and xenon using resonant, stepwise single-photon excitation are presented.

This interim report documents work carried out by Combustion Engineering, Inc. under a contract to Exxon Research and Engineering Company and was prepared by Combustion Engineering, Inc. This report is the second of two reports by Combustion Engineering, Inc. on the predevelopment phase of the Hybrid Boiler program and covers the results of an engineering design study of a Hybrid Boiler firing the vacuum distillation residue (vacuum bottoms) derived from processing Illinois No. 6 coal in the EDS Coal Liquefaction Process. The function of the Hybrid Boiler is to heat the coal slurry feed for an EDS coal liquefaction plant by a process coil in the convection section and to generate high pressure steam in the radiant section. The Hybrid Boiler design developed in this phase of the program is based on the results of a laboratory characterization program (reported in EDS Interim Report FE-2893-112), on Combustion Engineering, Inc.&#x27;s extensive experience as a designer and supplier of steam generating equipment, and on Exxon Research and Engineering Co.&#x27;s experience with the design and operation of process heaters.

Recent experimental results on production of prompt electrons in e/sup +/e/sup -/ annihilation at PEP are reviewed. The semielectronic branching ratios and the fragmentation functions of B- and C-mesons are discussed.

This report discusses the design and past applications of an explosive acoustic telemetry system (EATS) for gathering and transmitting data from seabed penetrators. The system was first fielded in 1982 and has since been used to measure penetrator performance on three other occasions. Descriptions are given of the mechanical hardware, system electronics, and software.

Steelhead trout reared in Idaho hatcheries for release during the 1984--1988 outmigrations were adipose fin clipped to differentiate between wild/natural and hatchery-reared fish. From 1984--1988, 34 million hatchery-reared steelhead trout were clipped and 30.1 million were released; the difference being made up by hatchery mortality and the percent of acceptable clips. Since 1987, the adipose clip has given protection to all wild/natural steelhead and identified them from hatchery stocks. 135 refs.

A series of in-reactor experiments were conducted using full-length 32-rod pressurized water reactor (PWR) fuel bundles as part of the Loss-of-Coolant Accident (LOCA) Simulation Program. The third materials experiment (MT-3) was the sixth in the series of thermal-hydraulic and materials deformation/rutpure experiments conducted in the National Research Universal (NRU) reactor, Chalk River, Ontario, Canada. The main objective of the experiment was to evaluate ballooning and rupture during active two-phase cooling in the temperature range from 1400 to 1500/sup 0/F (1030 to 1090 K). The 12 test rods in the center of the 32-rod bundle were initially pressurized to 550 psi (3.8 MPa) to insure rupture in the correct temperature range. All 12 of the rods ruptured, with an average peak bundle strain of approx. 55%. The UKAEA also funded destructive postirradiation examination (PIE) of several of the ruptured rods from the MT-3 experiment. This report describes the work performed and presents the PIE results. Information obtained during the PIE included cladding thickness measurements metallography, and particle size analysis of the cracked and broken fuel pellets.

A pulsed laser/pulsed EMAT (electromagnetic acoustic transducer) receiver system has been demonstrated for measuring the time of flight of acoustic signals in hot steel samples. Attenuation and signal-to-noise ratio are important parameters to be monitored. A continuous contact EMAT application was not achieved; thermal analysis found that contact times of 5 seconds with cooling times of 45 seconds are required at 1300/degree/C. The equipment requires field hardening and improved packaging before system reliability can be assessed. 22 refs., 35 figs. (DLC)

The entrance radial matching section is an extremely important part of any radio-frequency quadrupole (RFQ) linac. It allows a beam having time-independent characteristics to become adapted to the time-dependent focusing in the RFQ. The matching sections proposed in this paper are defined by a four-term potential function and are very effective over lengths of 3 ..beta.. lambda or longer. The fringe field at the RFQ exit is mainly of interest because of the time-varying on-axis potential. The beam can either lose or gain energy, depending on the shape of the fringe field. The same four-term potential function can be used for shaping the vanes at the exit so that the fringe fields can be controlled. This formulation also applies to exit radial matching sections, which would be useful if the beam is to enter another RFQ operated at a higher frequency. 4 references, 4 figures.

The Hanford Meterological Station (HMS) provides meteorological and climatological services to the Department of Energy in Richland and its contractors. On a 24-hour basis, the HMS measures, records, and archives meteorological data collected hourly throughout the year. The current data base consists of five components: wind telemetry stations, doppler acoustic sounders (SODAR), 200-ft towers, 410-ft tower at the HMS, and surface weather observations at the HMS. The wind telemetry station data, 410-ft tower data, and surface weather observation data are archived into yearly ACSII files, and the remaining components are permanently archived in binary from on magnetic tape. The future data base will consist of the same five components, but all components will be permanently archived into yearly ASCII files. Quality assurance computer programs will be written to validate the current data base, and data archival program will be written to improve the archival method that is currently used. 7 refs., 4 figs., 1 tab.
