Analysis of dimuon final states from 1.4 x 10/sup 11/ positive and 2.9 x 10/sup 10/ negative 209-Gev muons in a magnetized iron calorimeter has set a lower limit of 9 Gev/c/sup 2/ on the mass of a heavy neutral muon (M/sup 0/), and a 90%-confidence level upper limit of sigma(..mu..N..-->..b anti bX)B(b anti b..--> mu..X)<2.9 x 10/sup -36/ cm/sup 2/ for the production of bottom hadrons by muons. The dimuon mass spectrum from 102,678 trimuon final states places a 90%-confidence level upper limit for the muoproduction of upsilon states: sigma(..mu..N..--> mu.. UPSILON X)B(UPSILON..--> mu../sup +/..mu../sup -/)<22 x 10/sup -39/ cm/sup 2/. In addition, analysis of 71 rare multimuon events, including 4- and 5-muon final states, is presented.

A 1.26-mH superconducting solenoid made of NbTi and Cu-CuNi mixed matrix superconductor was designed and fabricated by Westinghouse Electric Corporation for the Los Alamos National Laboratory as part of the pulsed energy storage coil program. The coil was designed to store 400 kJ at a current of 25 kA and has been operated to currents of 20 kA. Development of high current cables and low-loss superconductors are both necessary undertakings for future fusion devices. The first tests of the coil involved a very slow charge of the coil followed by a rapid discharge in 1.07 ms with a capacitor bank and a normal-conductor load coil in a resonant L-C-L circuit. The second test consisted of a slow charge followed by a discharge and recharge on a time scale of a few seconds. This latter cycle resembles that expected in a tokamak induction coil. Loss measurements were made by an electrical method during the second series of tests.

Presented are results of a hydrogeochemical and stream sediment reconnaissance (HSSR) of the Iliamna NTMS quadrangle, Alaska. In addition to this abbreviated data release, more complete data are available to the public in machine-readable form. In this data release are location data, field analyses, and laboratory analyses of several different sample media. For the sake of brevity, many field site observations have not been included in this volume. These data are, however, available on the magnetic tape. Appendices A to D describe the sample media and summarize the analytical results for each medium. The data were subsetted by one of the Los Alamos National Laboratory (LANL) sorting programs into groups of stream sediment, lake sediment, stream water, lake water, and ground water samples. For each group which contains a sufficient number of observations, statistical tables, tables of raw data, and 1:1000000 scale maps of pertinent elements have been included in this report.

A trigger processor in operation since May 1980 at the Tagged Photon Spectrometer at Fermilab will be described. The processor, based on the Fermilab ECL-CAMAC system, allows fast selection of high mass diffractive events from the total hadronic cross section. Data from a recoil detector, consisting of 3 wire chambers and 4 layers of scintillator concentric about a 1.5 m liquid hydrogen target, is digitized and presented to the processor within 3 sec. From the chamber data are found the vertices and angles of all recoiling tracks.

Three main conclusions can be drawn from this work. For the FFTF and similar liquid metal fast reactors: (1) A simple ring-wise worth gradient does not adequately describe distortion reactivity effects of heterogeneous hexagonal components. (2) The chopped cosine-squared model for the axial shape of the distortion reactivity is not completely correct; the axial shape depends on radial position. (3) The presence of control rods in the core increases (in the negative direction) distortion reactivity, however, this effect is not large. The CORDIS code represents a cost efficient reactivity model which accounts for the core heterogeneity and control rod effects and also contains an improved axial model. Because of heterogeneity and control rod effects, it is important to calculate distortion reactivity with a comprehensive model such as the CORDIS code.

Soil samples from Test Area C-74L, Eglin Air Force Base, Florida, were analyzed for depleted uranium by instrumental epithermal neutron activation analysis. The sampling design used was a modified polar coordinate scheme. The resulting data were analyzed with a statistical procedure called kriging to obtain a contour map of concentration and a 95% confidence interval map. The majority of uranium remains in the center of the area near the target abutment.

This paper identifies the sulfuric acid step as the critical part of the thermochemical cycle in dictating the thermal demands and temperature requirements of the heat source. The General Atomic Sulfur-Iodine Cycle is coupled to a Tandem Mirror. The sulfuric acid decomposition process step is focused on specifically since this step can use the high efficiency electrical power of the direct converter together with the other thermal-produced electricity to Joule-heat a non-catalytic SO/sub 3/ decomposer to approximately 1250/sup 0/K. This approach uses concepts originally suggested by Dick Werner and Oscar Krikorian. The blanket temperature can be lowered to about 900/sup 0/K, greatly alleviating materials problems, the level of technology required, safety problems, and costs. A moderate degree of heat has been integrated to keep the cycle efficiency around 48%, but the number of heat exchangers has been limited in order to keep hydrogen production costs within reasonable bounds.

Portland cement grout identified as BCT-1-FF (Bell Canyon Test 1-FF) was used in borehole plugging experiments of the Bell Canyon Tests in Holl AEC-7 at the Waste Isolation Pilot Plant site in New Mexico during September 1979 and February 1980. This grout was made with fresh water. A study of this grout was begun in August 1979 in the laboratory to evauate the possible effects of temperature, pressure, and storage in fresh water or simulated groundwater (brine) on its phase composition and compressive strength at early ages. Phase composition was determined by X-ray diffraction. Temperatures ranged up to about 150/sup 0/F and included elevation at a few hours age after mixing; pressure was as high as 1500 psi; specimens were stored in simulated groundwater (brine) or in fresh water. Data from 1 to 90 days showed: (a) Higher temperature accelerated early strength gain. These differences essentially vanished by 90 days age. (b) Hydration products as identified by X-ray diffraction were normal; this indicated that a temperature range of 78 to 153/sup 0/F was not significant. (c) Pressure did not affect composition. (d) Storage in simulated groundwater (brine) or fresh water had no detectable effect. (e) Since the BCT-1-FF grout mixture …

Samples from Oklo Reactor zone-9 (ORZ-9) have been analyzed for the isotopic abundances of Nd, Ce, Ru, and Mo. Interpretation of the Nd data has begun as part of the effort to reconstruct the operating parameters of the reactor. The study of ORZ-9 and the peripheral rocks is being enhanced by additional analytical capabilities. A procedure was developed to measure uranium isotopic ratios with high precision. This new method was used for the analysis of rocks peripheral to ORZ-9. Two rocks containing relatively small quantities of uranium were depleted in /sup 235/U. The result demonstrates that small quantities of uranium were removed from the reactor zone and redistributed over distances of several tens of meters. Procedures are being designed to make high precision measurements of the relative abundances of barium isotopes. They will be used as part of a study of the transport of alkali and alkaline earth elements at Oklo. Samples from distances up to 300 meters from the known mineralized area at Oklo have been selected and prepared in an effort to identify element transport paths over longer distances. A sample from the Athabasca sandstone, overlying the uranium ores at Key Lake, and another from the transition zone …

It is proposed that direct detection of natural radioisotopes can be accomplished by using a very low energy (20 to 100 keV) cyclotron accelerating negative ions.

Measurements of cross sections for charge transfer and ionization of H/sub 2/ and rare-gas targets have been made with fast, highly stripped projectiles in charge states as high as 59+. We have found an empirical scaling rule for electron-capture cross section in H/sub 2/ valid at energies above 275 keV/amu. Similar scaling might exist for other target gases. Cross sections are generally in good agreement with theory. We have found a scaling rule for electron loss from H in collisions with a fast highly stripped projectile, based on Olson's classical-trajectory Monte-Carlo calculations, and confirmed by measurements in an H/sub 2/ target. We have found a similar scaling rule for net ionization of rare-gas targets, based on Olson's CTMC calculations and the independent-electron model. Measurements are essentially consistent with the scaled cross sections. Calculations and measurements of recoil-ion charge-state spectra show large cross sections for the production of highly charged slow recoil ions.

The relative merits of SiO/sub 2/, MgO and Al/sub 2/O/sub 3/ as insulation for nuclear instrument cables are investigated. Insulation resistance, voltage breakdown phenomena, capacitance, dissipation factors, and spurious voltage and current signals have been investigated on nuclear instrument cables under the combined effects of gamma irradiation (10/sup 5/ R/h) and temperature (to 450/sup 0/C). The SiO/sub 2/, MgO and Al/sub 2/O/sub 3/ cables tested were all fabricated to procedures that controlled insulation and backfill gas impurities. The SiO/sub 2/ cables possessed insulation resistances greater than 10/sup 10/ ..cap omega...ft at 450/sup 0/C and 10/sup 5/ R/h - nearly two decades higher than MgO or Al/sub 2/O/sub 3/ cables. Spontaneously generated currents as high as 250 nA dc were observed on some cables during thermal cycling tests.

A study was made to assess nuclear criticality safety in DOE Facilities and to assess the effects of various types of possible improvements. The accident statistics in DOE operations show that the fatalities caused by Nuclear Criticality accidents are small compared to other accident categories. The data show the safety performance after 1965, compared to prior years, was considerably improved indicating that overall safety programs have been effective. Data on criticality safety violations were collected from eight major facilities. These data were categorized by severity indexes and causes were assigned. A total of 421 violations were used in the data base for analysis in a fault tree model. Calculations were made using the fault tree methodology to show expected improvement in safety (reduction in probability of a criticality accident) for a fixed reduction in the number of criticality violations. Based on this analysis, about equal emphasis should be placed on reducing mechanical failures and operator errors as efforts in these two areas will likely produce the most significant improvements in safety. A criticality safety infraction form was prepared to facilitate uniformity in recording data on infractions for subsequent analysis. Discussions with Nuclear Safety Specialists working in the field instilled confidence …

The objective of this study is to conduct an assessment of gas-liquid direct-contact heat exchange and of a new storage-coupled system (the open-cycle Brayton/steam Rankine combined cycle). Both technical and economic issues are evaluated. Specifically, the storage-coupled combined cycle is compared with a molten salt system. The open Brayton cycle system is used as a topping cycle, and the reject heat powers the molten salt/Rankine system. In this study the molten salt system is left unmodified, the Brayton cycle is integrated on top of a Martin Marietta description of an existing molten salt plant. This compares a nonoptimized combined cycle with an optimized molten salt system.

The theory of longitudinal instabilities of bunched beams was proposed by F. Sacherer. Starting from the Vlasov equation, he derived the integral equation for the perturbed distribution function. While the general method to solve the integral equation was given by Sacherer, a number of other papers discussing longitudinal bunched beam instability have also been published. Here we want to propose another formalism with which we can treat the integral equation without mode coupling for the case of a Gaussian bunch. We then generalize the formalism for the other bunch distributions, and derive a practical method to analyze the instability for the case of a parabolic bunch. While the solution of the Sacherer equation that we find is not new, we present another approach to solve it. Since the integral equation for the transverse instability is similar to that for the longitudinal instability, this formalism is also useful for the transverse case. 12 figs., 4 figs.

The US Department of Energy (DOE) Morgantown Energy Technology Center has implemented a comprehensive program to demonstrate the technical and economic viability of coalbed methane as an energy resource. The program is directed toward solution of technical and institutional problems impeding the recovery and use of large quantities of methane contained in the nation's minable and unminable coalbeds. Conducted in direct support of the DOE Methane Recovery from Coalbeds Project, this study analyzes the economic aspects of a horizontal borehole methane recovery system integrated as part of a longwall mine operation. It establishes relationships between methane selling price and annual mine production, methane production rate, and the methane drainage system capital investment. Results are encouraging, indicating that an annual coal production increase of approximately eight percent would offset all associated drainage costs over the range of methane production rates and capital investments considered.

Testing results of the three major loose-fill insulation products marketed in this country subjected to a variety of vibrations and impacts in a laboratory setting to determine the magnitude of the resultant density increases, are presented. Results show repeated drops of 19 mm (.75 inch) and 152 mm (6 inch) produced density increases of up to 75% for fiberglass, 45% for rock wool, and 27% for cellulosic materials. The three insulation products were also subjected to vibrations ranging from 0.1 mm (.004 inch) to 6.35 mm (.25 inch) to obtain ratios of final density over initial density. Under the test conditions studied it was observed that the lighter materials settled more percentagewise than the dense materials.
