Measurement of the electroweak asymmetry in the reaction e/sup +/e/sup -/. -->. tau/sup +/tau/sup -/ at 29 GeV
This paper reports the electroweak asymmetry in the reaction e/sup +/e/sup -/ ..-->.. tau/sup +/tau/sup -/ at 29 GeV. The results came from data taken with the High Resolution Spectrometer at PEP corresponding to an integrated luminosity of 256 pb/sup -1/. The 7372 observed events give A/sub tau tau/ = -(4.4 +- 1.4 +- 0.5)%. Events selected in the central region of the detector measure a total cross section of R/sub tau tau/ = 1.06 +- 0.02 +- 0.04. 5 refs., 1 fig.

Multiplicity distributions in e/sup +/e/sup -/ annihilation at 29 GeV: a comparison with hadronic data
The charged particle multiplicity distributions for single jets in e/sup +/e/sup -/ annihilation at 29 GeV have been measured using the High Resolution Spectrometer at PEP. The shape of the distribution agrees well with a Poisson distribution. No correlation is observed between the multiplicities in the two jets of an event. For fixed values of the prong number of the total event, the multiplicity sharing between the two jets is in good agreement with a binomial distribution. These observations are contrasted to the results from soft hadronic collisions and conclusions are drawn about the nature of clusters. 21 refs., 4 figs.

Upper limit on the D*(2010) decay width
We report a measurement of the upper limit of the decay width for the D*/sup +/(2010) meson using the High Resolution Spectrometer at PEP. We observed the charged D* production in the decay mode of D*/sup +/ ..-->.. D/sup 0/..pi../sup +/ with the D/sup 0/ decaying into the K/sup -/..pi../sup +/ mode. The peak in the mass difference distribution M(K/sup -/..pi../sup +/..pi../sup +/)-M(K/sup -/..pi../sup +/) was used to directly measure the decay width. The width is dominated by the detector resolution and the preliminary result is an upper limit on the full width of GAMMA/sub D*/ < 1.15 MeV/c/sup 2/ at 90% C.L. 7 refs., 2 figs.

Stress corrosion cracking tests on high-level-waste container materials in simulated tuff repository environments
Types 304L, 316L, and 321 austenitic stainless steel and Incoloy 825 are being considered as candidate container materials for emplacing high-level waste in a tuff repository. The stress corrosion cracking susceptibility of these materials under simulated tuff repository conditions was evaluated by using the notched C-ring method. The tests were conducted in boiling synthetic groundwater as well as in the steam/air phase above the boiling solutions. All specimens were in contact with crushed Topopah Spring tuff. The investigation showed that microcracks are frequently observed after testing as a result of stress corrosion cracking or intergranular attack. Results showing changes in water chemistry during test are also presented.

Crystallographic Considerations of the Delta in Equilibrium. cap alpha. Displacive Transformation in Plutonium Alloys
Determination of invariant-plane strain crystallographic solutions for martensitic transformation between the FCC delta and monoclinic ..cap alpha.. phases in plutonium alloys, using three possible lattice correspondences and 53 possible lattice-invariant shear systems, identifies the most probable delta-..cap alpha.. lattice correspondence. The operative lattice-invariant shear systems are predicted by comparison of both shape strain magnitudes and computed interfacial energies. For delta ..-->.. ..cap alpha.. transformation twinning on (001) (100)/sub ..cap alpha../ is favored, giving a (.817, .538, .208)/sub delta/ habit and a (.947, .269, .174)/sub delta/ shape strain of magnitude m/sub 1/ = .324. The ..cap alpha.. ..-->.. delta transformation favors slip on (111) (101)/sub delta/, giving a (.255, .844, .471)/sub ..cap alpha../ habit and (.822, .466, .355)/sub ..cap alpha../ shape strain of magnitude m/sub 1/ = .417.

Patterns of fish assemblage structure and dynamics in waters of the Savannah River Plant. Comprehensive Cooling Water Study final report
Research conducted as part of the Comprehensive Cooling Water Study (CCWS) has elucidated many factors that are important to fish population and community dynamics in a variety of habitats on the Savannah River Plant (SRP). Information gained from these studies is useful in predicting fish responses to SRP operations. The overall objective of the CCWS was (1) to determine the environmental effects of SRP cooling water withdrawals and discharges and (2) to determine the significance of the cooling water impacts on the environment. The purpose of this study was to: (1) examine the effects of thermal plumes on anadromous and resident fishes, including overwintering effects, in the SRP swamp and associated tributary streams; (2) assess fish spawning and locate nursery grounds on the SRP; (3) examine the level of use of the SRP by spawning fish from the Savannah River, this objective was shared with the Savannah River Laboratory, E.I. du Pont de Nemours and Company; and (4) determine impacts of cooling-water discharges on fish population and community attributes. Five studies were designed to address the above topics. The specific objectives and a summary of the findings of each study are presented.

Two-phase alkali-metal experiments in reduced gravity
Future space missions envision the use of large nuclear reactors utilizing either a single or a two-phase alkali-metal working fluid. The design and analysis of such reactors require state-of-the-art computer codes that can properly treat alkali-metal flow and heat transfer in a reduced-gravity environment. A literature search of relevant experiments in reduced gravity is reported on here, and reveals a paucity of data for such correlations. The few ongoing experiments in reduced gravity are noted. General plans are put forth for the reduced-gravity experiments which will have to be performed, at NASA facilities, with benign fluids. A similar situation exists regarding two-phase alkali-metal flow and heat transfer, even in normal gravity. Existing data are conflicting and indequate for the task of modeling a space reactor using a two-phase alkali-metal coolant. The major features of past experiments are described here. Data from the reduced-gravity experiments with innocuous fluids are to be combined with normal gravity data from the two-phase alkali-metal experiments. Analyses undertaken here give every expectation that the correlations developed from this data base will provide a valid representation of alkali-metal heat transfer and pressure drop in reduced gravity.

Tokamak power system studies at ANL
The following features, in particular, have been examined: (a) large aspect ratio (A approx. = 6), which may ease maintenance; (b) high beta (..beta.. greater than or equal to 0.20) without indentation, which brings the maximum toroidal field down to about 6 to 7 T; (c) low toroidal current (I approx. = 4MA), which reduces the cost of the current drive and equilibrium field system; and (d) steady state operation with current density control via fast and slow wave current drive. The key to high beta operation with low toroidal current lies in utilizing second stability regime equilibria with the required current distributions produced by an appropriate selection of wave driver frequencies and power spectra. The ray tracing and current drive calculation is self-consistent with the actual magnetic fields they produce in the plasma. The impurity control activities in TPSS have emphasized the self-pumping concept as applied to using the entire first wall or ''slot'' limiters. The blanket design effort has emphasized liquid metal and Flibe concepts. The reference concept is a liquid lithium/vanadium, self-cooled configuration. Overall, there exists a number of major design improvements which will substantially improve the attractiveness of tokamak reactors.

Population Dose Commitments Due to Radioactive Releases From Nuclear Power Plant Sites in 1982. Volume 4
Population radiation dose commitments have been estimated from reported radionuclide releases from commercial power reactors operating during 1982. Fifty-year dose commitments from a one-year exposure were calculated from both liquid and atmospheric releases for four population groups (infant, child, teen-ager and adult) residing between 2 and 80 km from each of 51 sites. This report tabulates the results of these calculations, showing the dose commitments for both liquid and airborne pathways for each age group and organ. Also included for each site is a histogram showing the fraction of the total population within 2 to 80 km around each site receiving various average dose commitments from the airborne pathways. The total dose commitments from both liquid and airborne pathways ranged from a high of 30 person-rem to a low of 0.007 person-rem for the sites with plants operating throughout the year with an arithmetic mean of 3 person-rem. The total population dose for all sites was estimated at 130 person-rem for the 100 million people considered at risk. The average individual dose commitment from all pathways on a site basis ranged from a low of 6 x 10/sup -7/ mrem to a high of 0.06 mrem. No attempt was made …
