A kaon beam line operating in the range from 1.0 to 2.0 GeV/c is proposed. The line is meant for kaon and pion research in a region hitherto inaccessible to experimenters. Topics in hypernuclear and kaon physics of high current interest include the investigation of doubly strange nuclear systems with the K/sup -/,K/sup +/ reaction, searching for dibaryon resonances, hyperon-nucleon interactions, hypernuclear ..gamma.. rays, and associated production of excited hypernuclei. The beam line would provide separated beams of momentum analyzed kaons at intensities greater than 10/sup 6/ particles per spill with a momentum determined to one part in a thousand. This intensity is an order of magnitude greater than that currently available. 63 references.

Pacific Northwest Laboratory has initiated a review of the Safeguards and Security systems at the Critical Mass Laboratory with regards to determining appropriate upgrading actions that assure that an effective and efficient Safeguards and Security posture consistent with DOE-RL policies, procedures, and priorities is effected. As a result of this review, PNL has concluded that specific upgrades are required at CML that provide a demonstrated enhancement to the overall security posture of the facility and are based upon prudent expenditures of government funds. It was further concluded that additional recommended upgrades provide minimal improvement to the overall security system at a significant outlay of funds.

This report summarizes extensive research by staff of the Solar Energy Research Institute and its subcontractors conducted to establish the origin and possible amelioration of acoustic disturbances associated with the operation of the DOE/NASA MOD-1 wind turbine installed in 1979 near Boone, North Carolina. Results have shown that the source of this acoustic annoyance was the transient, unsteady aerodynamic lift imparted to the turbine blades as they passed through the lee wakes of the large, cylindrical tower supports. Nearby residents were annoyed by the low-frequency, acoustic impulses propagated into the structures in which the complainants lived. The situation was aggravated further by a complex sound propagation process controlled by terrain and atmospheric focusing. Several techniques for reducing the abrupt, unsteady blade load transients were researched and are discussed in the report.

Fuel performance models based on empirical evidence are used to predict particle failure and fission product release in the design of high-temperature gas-cooled reactors (HTGRs). Advances in HTGR fuel performance models have improved the agreement between observed and predicted performance and contributed to an enhanced position of the HTGR with regard to investment risk and passive safety. Heavy metal contamination is the source of about 55% of the circulating activity in the HTGR during normal operation, and the remainder comes primarily from particles which failed because of defective or missing buffer coatings. These failed particles make up about 5 x 10/sup -4/ fraction of the total core inventory. In addition to prediction of fuel performance during normal operation, the models are used to determine fuel failure and fission product release during core heat-up accident conditions. The mechanistic nature of the models, which incorporate all important failure modes, permits the prediction of performance from the relatively modest accident temperatures of a passively safe HTGR to the much more severe accident conditions of the larger 2240-MW(t) HTGR.

We describe the broad band neutrino beam in the north area of the AGS and discuss the calculation of the neutrino flux. The horns were initially designed by Robert Palmer and this beam has been used for almost all neutrino running at the AGS. All of the wide band running for E734 has been done in the beam we discuss. E734 is an experiment designed to measure elastic scattering of neutrinos and antineutrinos on electrons and protons. The detector is sufficiently large (approx. =170 tons) that enough events can be detected to make precision measurements of cross sections. In particular, the reaction nu/sub ..mu../ + e ..-->.. nu/sub ..mu../ + e has been detected with more than 100 events, requiring a detailed understanding of the beam characteristics for normalization.

The flow and bottomhole pressure data have been analyzed for the two sands (Nos. 8 and 9) tested by the Gladys McCall No. 1 well. The more productive sand (No. 8) appears to be bounded by two linear faults at distances of approx. 740 feet and approx. 1360 feet from the well and there appears to be a decrease in the formation transmissivity away from the well. The formation properties inferred from the well test analysis have been used with a reservoir simulator to match the bottomhole drawdown/buildup history measured during the Reservoir Limits Test of Sand Zone No. 8. Wellhead pressure data measured during the long-term production testing of Sand Zone No. 8 have been employed to estimate the corresponding downhole pressures. The simulation model based solely on the Reservoir Limits Test is found to be in remarkably good agreement with the estimated bottomhole pressures for the first six months of production testing, but enlargement of the reservoir volume, by moving the boundary most remote from the well outward, is required to adequately match the full production history.

Conventional reservoir engineering studies have, in the past, dealt mainly with interpretation of pressure transient effects in a reservoir. Present-day techniques can be used in many reservoirs to forecast with some reliability the probability, magnitude and timing of pressure interference among wells. However, forecasting fluid breakthrough from an injection well to a production well in geologically complex geothermal reservoirs is not presently possible with any reliability, and forecasting thermal breakthrough is even more difficult. In addition, the chemical effects of injection are poorly understood at present, and it is not possible to predict beforehand the full range of scaling and aquifer plugging problems that may be encountered. This report discusses development of chemical tracers specifically designed for geothermal applications so that breakthrough of injectate can be detected early, and field and laboratory studies on the chemical interactions among reservoir fluids, reservoir rocks and injected fluids so that these interactions can be quantified and models developed for predicting any degradation (or enhancement) of permeability.

During the past decade, intensive research and development has demonstrated the feasibility, checked the accuracy, and extended the sensitivity of laser diagnostics for combustion systems. Combinations of diagnostics can now provide in-situ, time-, and space-resolved measurements of temperature, velocity, and species concentration. Although these tools are powerful, they also can be exceedingly difficult to use, and their application remains largely in the hands of specialized instrument developers rather than problem-oriented researchers. This report outlines a variety of applications for existing diagnostics that may interest both instrument developers and researchers in particular fields.

Comprehensive spectroscopic data tables are presented for all ions of Fe. Tables of ionization potentials, wave lengths of spectral lines, atomic energy levels, and transition probabilities are given which were excerpted from general critical compilations. All utilized compilations are less than five years old and include data on electric dipole as well as magnetic dipole transitions.

This report provides a handbook of data concerning particle solid interactions that are relevant to plasma-wall interactions in fusion devices. Published data have been collected, assessed, and represented by a single functional relationship which is presented in both tabular and graphical form. Mechanisms reviewed here include sputtering, secondary electron emission, particle reflection, and trapping.

Two automated nondestructive assay instruments developed at Los Alamos in support of nuclear materials accounting needs are currently operating in-line at the Oak Ridge Y-12 facility for recovery of highly enriched uranium (HEU). One instrument provides the HEU inventory in the secondary solvent extraction system, and the other monitors HEU concentration in the secondary intermediate evaporator. Both instruments were installed in December 1982. Operational evaluation of these instruments was a joint effort of Y-12 and Los Alamos personnel. This evaluation included comparison of the solvent extraction system inventories with direct measurements performed on the dumped solution components of the solvent extraction system and comparison of concentration assay results with the external assays of samples withdrawn from the process. The function and design of the instruments and detailed results of the operational evaluation are reported.

This report talks about Beam-Beam Limited Luminosity

In order to control emittance growth due to transverse wakefields it will be necessary to transport electrons and positrons through the Stanford Linear Collider (SLC) linac to within a hundred ..mu..m of the centers of the linac irises. Beam centering will be accomplished using computer routines to read stripline beam position monitors and in turn correct the orbits with dipole magnets. Several different steering algorithms have been investigated using electrons in the first third of the SLC linac lattice. The most promising scheme is a cascade of modified ''three-bumps'' in conjunction with long spanning harmonic corrections. General features of the orbit correcting software are discussed along with the mathematical recipes for correction. Experimental results and a discussion of future plans are presented.

Louis De Broglie and M. Capek have described some interesting similarities between the philosophical ideas of Henri Bergson and the profound conceptual changes introduced into physics by quantum theory and the theory of relativity. These similarities are neither identities nor direct causal links, and hence physicists are likely to regard them as mere curiosities having no import for the development of science. However, another view is possible: if Bergson's thinking presaged, at least in spirit, these two revolutionary advances in physics then his intuitions may accord sufficiently with nature to provide useful guidance in the approach to other deep problems in science. Pursuing this idea I shall indicate here how Bergson's intuitions suggest a possible approach to perhaps the fundamental problem of contemporary science, namely the problem of constructing an overarching theoretical framework for unifying the various branches of science from psychology through biology to physics. 19 refs.

A nonlinear, multivariable, blanket optimization technique is applied to the Cascade inertial confinement fusion reactor concept. The thickness of a two-zone blanket, which consists of a BeO multiplier region followed by a LiAlO/sub 2/ breeding region, is minimized subject to constraints on the tritium breeding ratio, neutron leakage, and heat generation rate in Al/SiC tendons that support the chamber wall.

The craters from high-yield nuclear tests at the Pacific Proving Grounds are very broad and shallow in comparison with the bowl-shaped craters formed in continental rock at the Nevada Test Site and elsewhere. Attempts to account for the differences quantitatively have been generally unsatisfactory. We have for the first time successfully modeled the Koa Event, a representative coral-atoll test. On the basis of plausible assumptions about the geology and about the constitutive relations for coral, we have shown that the size and shape of the Koa crater can be accounted for by subsidence and liquefaction phenomena. If future studies confirm these assumptions, it will mean that some scaling formulas based on data from the Pacific will have to be revised to avoid overestimating weapons effects in continental geology. 9 refs., 5 figs.

This report concludes a preliminary report prepared by ANL for Sandia, published as NUREG/CR-3855, in June 1984. The preliminary report, NUREG/CR-3855, presented the results of a survey of nuclear reactor containment penetrations, covering the number of plants surveyed at that time (22 total). Since that time, an additional 26 plants have been included in the survey. This final report serves two purposes: (1) to add the summary data sheets and penetration details for the additional plants now included in the survey; and (2) to confirm, revise, or add to analyses and discussions presented in the first report which, of course, were based solely on the earlier sample of 22 plants. This final report follows the outline and format of the preliminary survey report. In general, changes and additions to the preliminary report are implied, rather than stated as such to avoid repeated reference to that report. If no changes have been made in a section the title of the section of the previous report is simply repeated followed by ''No Changes''. Some repetition is used for continuity and clarity.

The Basalt Waste Isolation Project (BWIP) Materials Testing Group (MTG) provides large quantities of reference basalt for testing waste package materials under repository conditions, site sorption characteristics and other experimental purposes. This document describes the reference rock materials currently used in testing, namely entablature and colonnade basalt from the Umtanum and Cohassett flows. The data include sampling locations, bulk chemical composition, modal percentages of major phases, and the chemical and mineralogical compositions of these phases. 8 refs., 17 figs., 15 tabs.

A new L-edge densitometer has been designed around a compact, commercial x-ray generator weighing less than 5 kg. The dc generator x-ray spectrum was tailored to produce a continuum of x-ray energies from 14 to 20 keV. The x rays were transmitted through uranium reference solutions, and the measured transmissions near the uranium L/sub III/-absorption edge were used to compute the uranium concentration assay result. The range of uranium concentrations in the reference solutions included 5 to 50 g/l. In this concentration range, the assay uncertainty for short count times and the flatness of the specific assay response were better than 0.5%. Thus, the precision and accuracy of this compact densitometer are equal to those demonstrated previously for the L-edge technique. The compact dimensions and optimized transmission geometry increase the practicality, versatility, and range of the L-edge applications. 12 references, 12 figures, 4 tables.

Data on the change of detonation velocity and Chapman-Jouget pressure vs initial HE density for RDX and HMX have been compared with the theoretical predictions of Ree for PBX 9404. Ree's model predicts breaks or changes in the slope of these curves due to the solidification of carbon and the formation of a separate, nitrogen-rich phase. There is good evidence for the solidification of carbon at rho/sub 0/ about 1.15 g/cc, but the evidence for the nitrogen phase separation at rho/sub 0/ about 1.56 g/cc is conflicting. 14 refs., 6 figs., 1 tab.

This writeup is an attempt to calculate some of the cooldown parameters of a long string of magnets such as the case might be for the SSC. Besides the cooldown time, temperature gradients along a magnet, and in the transverse direction, are influenced by the mass flow of the refrigerant. A number of assumptions and simplifications have been made so that an analytical solution can be obtained. Part I of this report assumes a one dimensional model with a finite axial conductivity and infinite transverse conductivity. Part II, considers the cooldown in the transverse direction only. A common example for both parts points out the limitation of the assumptions made in Part I and suggests the need for a two dimensional time dependent model T = T(r,z,t).

Consideration is given to quantum fluctuations, intra beam scattering, cooling rates, and ring acceptance in order to see if one can obtain a normalized emittance of 10/sup -8/ in any plausible cooling ring. It is concluded that only a small gain is obtained by varying the partition functions, but a very significant gain is made by using higher bending fields. The ring is found to get bigger if the magnet apertures are increased. The ring diameter is found to increase if the momentum spread of the beam is reduced. It is shown that the power can be reduced by allowing a high beamstrahlung energy loss resulting in higher current in the cooling ring. Parameters are also given for a 10/sup -7/ m radian emittance case. (LEW)

A counter current extraction system is proposed here to recover tritium from /sup 17/Li-/sup 83/Pb. The multiple stage extraction system is used to reduce the resistance to the molecular diffusion in the liquid phase, while a counter current helium purge gas is used to reduce the resistance in the gas phase. To reduce the purge gas requirement and alleviate the tritium containment problem, hydrogen is added to the purge gas. An isotope separation system is designed to separate the hydrogen from the tritium.

This paper reviews research in the United States and Japan on structural materials for high-field superconducting magnets. Superconducting magnets are used for magnetic fusion energy devices and for accelerators that are used in particle-physics research. The cryogenic structural materials that we review are used for magnet cases and support structures. We expect increased materials requirements in the future.
