Hot plasma buildup by neutral beam injection into an initially cold solid or gaseous target is found to be conceivable in large mirror machine experiments such as 2XIIB or MFTF. A simple analysis shows that existing neutral beam intensities are sufficient to ablate suitable targets to form a gas or vapor cloud. An approximate rate equation model is used to follow the subsequent processes of ionization, heating, and hot plasma formation. Solutions of these rate equations are obtained by means of the ''GEAR'' techniques for solving ''stiff'' systems of differential equations. These solutions are in rough agreement with the 2XIIB stream plasma buildup experiment. They also predict that buildup on a suitable nitrogen-like target will occur in the MFTF geometry. In 2XIIB the solutions are marginal; buildup may be possible, but is not certain.

A series of drift-surface and magnetic-field calculations has been carried out to try to estimate the accuracy with which the elements of the TMX magnet set must be magnetically aligned. The results of these calculations, for 500 G at the solenoidal center, are summarized.

A contract was awarded in June 1976 for the installation of a solar space heating and domestic hot water system at 2400 Watteroon Trail, Louisville, Kentucky. The overall philosophy used was to install both a liquid and a hot air system retrofitted to the existing office and combined warehouse building. The 1080 sq ft office space is heated first and excess heat is dumped into the warehouse. The two systems offered a unique opportunity to measure the performance and compare results of both air and liquid at one site. The two systems are described in detail and information on the data acquisition system is included.

During recent years numerous documents in the form of codes and standards have been developed and published to provide design, fabrication and construction rules and criteria applicable to instrumentation, control and power distribution facilities for nuclear power plants. The contents of this LTR were prepared by NUS Corporation under Subcontract K5108 and provide a consolidated index and listing of the documents selected for their application to procurement of materials and design of modifications and new construction at the LOFT facility. These codes and standards should be applied together with the National Electrical Code, the ID Engineering Standards and LOFT Specifications to all LOFT instrument and electrical design activities.

The Spar and Sphere offshore platforms are feasible concepts for the demonstration of a near full size OTEC plant to determine its validity and to gather data for use in the construction, design and operation of commercial OTEC plants. A hull size suitable to support a 100 MWe net output plant was chosen. Either 50, 25 or 12.5 MWe power modules could be used. Selection of 50 MWe modules would permit the testing of equipment recommended for the commercial plant. The use of 25 MWe modules would permit optimal hull volume utilization. The size hull selected for both platforms represents a reasonable increase above the pilot plant, providing design and construction problems similar to those that may be found in a hull size commercial plant. Since the hull size is substantially smaller than the projected commercial plant size, the possiblity of constructing the vessel of steel was presented. However, it is already determined that the full size hull shall be constructed principally of reinforced concrete and thus to fully demonstrate the feasibility of both construction techniques and operation, concrete was chosen for the demonstration plant. The superstructure of the sphere is all steel and for the spar, concrete with a …

The configuration, integration, and evaluation studies performed in the first phase of this contract resulted in a ranking of the most feasible platform candidates for commercial OTEC applications. On the basis of the results obtained from three individual contractors performing the same study, the Department of Energy made selections of two platform hulls for each contractor for conceptual designs. For Phase-II studies, M. Rosenblatt and Son, Inc. (MR and S) project team was given the SPAR and SPHERE platforms to perform not only conceptual designs for, but also cost and time schedules and sensitivity analyses. This is the second volume of a three-volume MR and S report, and it presents the results of conceptual designs for the two platforms, the facilities and equipment required for construction, deployment, and operation of these platforms, and cost estimates and time schedules. All conceptual design work is performed for the baseline site on West Coast of Florida. The cost differentials and other considerations involved with deploying the platforms in the New Orleans and Puerto Rico sites are also presented. As an end product of the complete study, the costs for the SPAR and the SPHERE platforms are reported both in terms of acquisition costs …

Energy-dependent evaluated photon interaction cross sections and related parameters are presented for elements H through Cf (Z = 1 to 98). Data are given over the energy range from 0.1 keV to 100 MeV. The related parameters include form factors and average energy deposits per collision (with and without fluorescence). Fluorescence information is given for all atomic shells that can emit a photon with a kinetic energy of 0.1 keV or more. In addition, the following macroscopic properties are given: total mean free path and energy deposit per centimeter. This information is derived from the Livermore Evaluated-Nuclear-Data Library (ENDL) as of October 1978

The results of a dynamic analysis of the LOFT Reactor Core Barrel for faulted conditions are presented in this report. Loading conditions considered were seismic accelerations resulting from a Safe Shutdown Earthquake (SSE) and pressure loadings from both a hot leg and a cold leg Loss-of-Coolant Accident (LOCA) break. Maximum stresses in the core barrel, resulting from these conditions, are presented with comparisons to Code allowables. Stresses were found to be within allowables for the faulted condition as defined in the ASME Code (1977), Appendix F.

My major impression of the Staff Draft ''Geothermal Policy Option Paper...'' is that notwithstanding repeated statements that geothermal development is to be encouraged by streamlining the regulatory siting process, the ERCDC is trying to confer on itself jurisdiction over the exploratory development of the resource; thus, expanding regulatory involvement. The Staff is proposing alternative methods of asserting control over the county's conditional use--EIR process. The Warren-Alquist Act simply does not grant siting jurisdiction to the Energy Commission for exploratory steam well drilling. For the Staff to say that the Commission simply chooses not to take jurisdiction is to ignore the statutory scheme regulating geothermal development and serves to reinforce a posture justifying extensive control over the county's land use prerogative.

Steady-state critical heat flux experiments have been performed in the Forced Convection Test Facility (FCTF), an annular test section containing a single electrically heated rod, for the purpose of testing the applicability of existing critical heat flux correlations. Good accuracy has been obtained using the MacBeth-Barnett critical heat flux correlation for annuli, corrected for the ''stepped cosine'' power profile of the heater. The equivalent diameter of the test section, based on the wetted perimeter, is 2.1 cm (0.83 in.); the heated-to-wetted-perimeter ratio is 0.252. The heated length of the heater rod is 366 cm (144 in.). Nominal pressures for the tests have ranged from 7.2 to 15.5 MN/m/sup 2/ (1044 to 2250 psia); coolant flow rates have been 0.32 dm/sup 3//sec (5 gpm), 0.63 dm/sup 3//sec (10 gpm), and 1.26 dm/sup 3//sec (20 gpm); and heater powers of 72 kW, 122 kW, and 144 kW have been used. Maximum error in prediction of first observed critical heat flux is 21 percent; rms error is 11.7 percent. Attempts have also been made to predict the occurrence of critical heat flux during blowdowns (depressurization transients) of the FCTF. The results of these predictions are inconclusive at this time.

A crack-free silicon ingot has been cast in a graded, semiconductor purity silica crucible. More than 90% single crystallinity has been achieved in 2.5 kg cast ingots. The impurities on the surface of the melt have been reduced with the use of a rapid heat-up cycle and absence of graphite retainers. Solar cells fabricated out of HEM cast material have shown conversion efficiency up to 14% under AM1 Xenon source illumination. Considerable progress has been achieved in casting square cross-section ingots. The growth in the corners has been obtained but the problem area is in fabricating a custom-made graded crucible. Kerf loss was reduced to 6.2 mil, 0.155 mm in slicing 4 cm x 4 cm cross-section with 100% yield. The abrasive life of plated impregnated blades was increased by hardening the electroless nickel layer. In an effort to prevent diamond pull-out and thereby improve the abrasive life, the plated layer was increased from 0.3 mil, 7.5 ..mu..m to 0.5 mil, 12.5 ..mu..m. The extra thickness buried the diamonds. A thinner copper sheath for impregnation and a thicker nickel coating to prevent diamond pull-out is expected to improve the abrasive life. Higher feed forces increased the cutting rates but resulted …

Decades of human semen studies have yielded compelling evidence that sperm can be used to access reproductive potential and diagnose pathology. With these studies as background, the small number of detailed semen studies of men exposed to physical and chemical agents point with optimism to the application of human semen assays as efficient, effective means to monitor for reproductive hazards in the workplace. Sperm are the most accessible of human gonadal tissue and provide a means of monitoring exposure induced changes in the human testes, changes which may result in infertility and increased frequencies of genetically abnormal gametes. The focus on semen has precipitated the development of new sperm bioassays which use older conventional andrological methods (i.e., sperm counts, motility, and morphology) as well as recently developed high speed flow and scanning methods for automated cytological analyses. The status of these sperm assays for workplace surveillance is reviewed, procedures are suggested with examples of use, and their effectiveness is evaluated. The available mouse models of induced semen changes are briefly described and the importance of these models for evaluating the genetic implications of findings in human semen is discussed.

Future prospects regarding the numerical solution of the Navier-Stokes equations using the finite element method are discussed. Since the ultimate goal is to solve these equations in three-dimensions, only the primitive variable (u,P) formulation is considered. A novel feature of the two-dimensional solution technique relates to the methodology developed and employed for solving the semi-discretized system of ordinary differential equations, which are outlined in the section describing the development of the two-dimensional code. Following the discussion of numerical results from two-dimensional calculations, three-dimensional flows are discussed, where several potentially viable options are considered. (TFD)
