Research was conducted on photosensitizers for the norbornadiene to quadricyclene conversion.

The effort included the design, fabrication and Systems Verification Testing of the Deep Drilling System. The Systems Verification Test was conducted during October 1978 in a test well located on the premises of Brown Oil Tools Inc., Houston, Texas. In general, the Systems Verification test program was an unqualified success. All of the system elements of the Deep Drilling System were exercised and evaluated and in every instance the system can be declared ready for operational well demonstration. The motor/bit shaft combination operated very well and seal performance exceeds the design goals. The rig floor system performed better than expected. The power cable flexural characteristics are much better than anticipated and longitudinal stability is excellent. The prototype production connectors have functioned without failure. The cable reels and drive skid have also worked very well during the test program. The redesigned and expanded instrumentation subsystem also functioned very well. Some electronic component malfunctions were experienced during the early test stages, but they were isolated quickly and repaired. Subsequent downhole instrumentation deployments were successfully executed and downhole data was displayed both in the Electrodril instrumentation trailer and on the remote control and display unit.

An inexpensive boron-loaded liner of epoxy resin for fissile-material storage containers was developed that can be easily fabricated of readily available, low-cost materials. Computer calculations indicate reactivity will be reduced substantially if this neutron-absorbing liner is added to containers in a typical storage array. These calculations compare favorably with neutron-attenuation experiments with thermal and fission neutron spectra, and tests at the Fire Test Facility indicate the epoxy resin will survive extreme environmental and accident conditions. The fire-resistant and insulating properties of the epoxy-resin liner further augment its ability to protect fissile materials. Boron-loaded epoxy resin is adaptable to many tasks but is particularly useful for providing enhanced criticality safety in the packaging and storage of fissile materials.

Mechanical Technology Incorporated is developing a 1 KWe Free-Piston Stirling ENgine (FPSE) Power System. The plan for testing the demonstrator power system is presented. The test hardware is a Free-Piston Stirling Engine prime mover driving a linear alternator. The demonstrator system is basically a modular assembly. The modules are the reciprocating alternator section, engine section, heater head insulation package assembly, and the pressure vessel. The test objective is to demonstrate a system with greater than 30% overall efficiency at 1 KW, 45 hz operating conditions, and to identify and isolate engine losses to provide a basis for future engine improvements.

The results of a program designed to develop a laser heated plasma sample for atomic physics studies in the 30 to 100 eV range of electron temperature and the 3 x 10/sup 17/ to 10/sup 18/ cm/sup -3/ range in electron density are presented. The approach used was discussed in detail in Mathematical Sciences Northwest, Inc., (MSNW) Proposal 1660, that is, the laser breakdown mode of heating in a slow solenoid. An extensive rework of the plasma sample facility was done in order to use this mode of heating. Specifically, a new solenoid magnet was constructed to allow higher field operation and the plasma chamber was modified to allow the use of puff filling orifices and small bore tube liners. The vacuum system and focussing optics were changed to allow the use of an on-axis Cassagranian system capable of focussing the laser radiation to a nearly diffraction limited spot as is necessary when heating through a small aperture. The 10 liter CO/sub 2/ laser optics were charged to an unstable oscillator configuration and additional windows were provided into the optical cavity for alignment purposes.

In high explosives machining the three major concerns are safety, reliability, and ease of operation. With these three concerns as our main goals, LLL's EE and ME departments worked together to modify a LeBlond precision lathe for high explosives machining. The result is a unique, remote-controlled lathe which has extensive mechanical and electronics modifications. The lathe has been operating safely and successfully at Site 300's HE Test Facility since April 1978.

The Alpha Fuels Environmental Test Facility (AFETF) impact gun is a unique tool for impact testing /sup 238/PuO/sub 2/-fueled heat sources of up to 178-mm dia at velocities to 300 m/s. An environmentally-sealed vacuum chamber at the muzzle of the gun allows preheating of the projectile to 1,000/sup 0/C. Immediately prior to impact, the heat source projectile is completely sealed in a vacuum-tight catching container to prevent escape of its radioactive contents should rupture occur. The impact velocity delivered by this gas-powered gun can be regulated to within +-2%.

Progress in developing mathematical models to describe combustion conditions with and without swirl in automotive engine combustion chambers and calculations performed with these models are discussed. (LCL)

The stress analysis performed on the 1''-PCC-76-A piping system inside containment penetration S-1A is described. Deadweight, thermal expansion, and seismic loads were considered. Results of this analysis show that the subject piping system will meet ASME Boiler and Pressure Vessel Code, Section III, Class 2 requirements provided that supports S8 and S9 are installed as recommended.

Using the transient method, we determine the permeability of high-quartz Eleana argillite from the Nevada Test Site as a function of effective pressure. By comparing calculated and observed pressure decay in the upstream reservoir, we have determined the permeability of intact and fractured specimens at effective pressures ranging from 1.0 to 24.0 MPa. Over this pressure range, Eleana argillite has a low permeability (10{sup -16} to 10{sup -19} cm{sup 2}) when intact and a higher permeability (10{sup -12} to 10{sup -17} cm{sup 2}) with one induced through-going fracture.

The first part discusses the design and results of a /sup 252/Cf-neutron and a 14-MeV neutron benchmark experiment for verifying previously developed theoretical methods for use in the design of a neutron logging tool for uranium borehole exploration. The second part discusses the Science Applications, Inc. (SAI) development of a fast fission monitor for measuring 14-MeV neutrons for a D-T borehole sonde in a high neutron moderating and absorbing environment. The 14-MeV pulsed neutron monitor was used in carrying out the 14-MeV neutron benchmark experiment, and a variation on the method of quantitatively counting many events in one burst of pileup counts, developed for the 14-MeV-pulsed neutron monitor, was employed in successfully counting the epithermal neutrons produced by a short (2 ..mu..s) burst of 14-MeV neutrons. Thus, the development of the 14-MeV-neutron monitor and the measurements with 14-MeV neutrons were intimately related.

An account is given of the obervations of the pitch angle distributions of energetic particles in the near equatorial regions of the Earth's magnetosphere. The emphasis is on relating the observed distributions to the field configuration responsible for the observed effects. The observed effects relate to drift-shell splitting, to the breakdown of adiabatic guiding center motion in regions of sharp field curvature relative to partial gyro radii, to wave-particle interactions, and to moving field configurations. 39 references.

Policy measures which could be part of a Federal program to encourage energy conservation in renter-occupied housing are discussed. The report summarizes data on the renter-occupied housing stock and energy consumption specific to structure type, functional use, fuel type, and region. Energy conservation opportunities and factors which impede the realization of those opportunities are identified. Incentives and programs are suggested that could reduce energy consumption in rented housing. A number of issues of programmatic significance, considering several concepts which could form the basis for demonstration programs under Section 509 of ECPA, are discussed. The potential costs and benefits of a national program stemming from the demonstration efforts are discussed. (MCW)

This information is derived from the Livermore Evaluated-Nuclear-Data Library (ENDL) as of October 1978

Simulated transient tests were conducted on 234 cladding specimens from EBR-II irradiated mixed oxide fuel pins; approximately 75% of the specimens were from the fuel column region, with the remainder from the plenum and below the fuel column. The cladding specimens were taken from the N-E, N-F,, PNL-9, PNL-10, PNL-11, P-23A, P-23B, P-23C, and WSA-3 fuel pins irradiated at 15.2 to 37 KW/cm to burnup levels from 11 to 110 MWd/Kg. All the fuel pins used 20% cold worked Type 316 stainless steel cladding. Irradiation temperatures ranged from 370 to 725/sup 0/C with a peak fluence of 10/sup 23/ n/cm/sup 2/ (E > 0.1 MeV).

A technique has been developed to fabricate poly-Si electrodes for charge-coupled devices. By controlling the microstructure of a poly-Si film, an anisotropic etchant was selected to provide essentially uniform electrode width dimensions. The electrode widths have only a 6% variation for the majority of the devices over the area of a 2 inch silicon wafer.

The purpose of this investigation was to determine the corrosion behavior of a high strength steel (ASTM A416-74 grade 270), typical of those used as tensioning tendons in prestressed concrete pressure vessels, in several corrosive environments and to demonstrate the protection afforded by coating the steel with either of two commercial petroleum-base greases or Portland Cement grout. In addition, the few reported incidents of prestressing steel failures in concrete pressure vessels used for containment of nuclear reactors are reviewed. The susceptibility of the steel to stress corrosion cracking and hydrogen embrittlement and its general corrosion rate were determined in several salt solutions. Wires coated with the greases and grout were soaked for long periods in the same solutions and changes in their mechanical properties were subsequently determined. All three coatings appeared to give essentially complete protection but small flaws in the grease coatings were detrimental; flaws or cracks less than 1 mm wide in the grout were without effect.

Most detailed fusion target design is done by numerical simulation using large computers. Although numerical simulation is briefly discussed, this lecture deals primarily with the way in which basic physical arguments, driver technology considerations and economical power production requirements are used to guide and augment the simulations. Physics topics discussed include target energetics, preheat, stability and symmetry. A specific design example is discussed.

Preliminary studies were made on a unique dielectric system for both flexible and rigid power cable applications. Known as Spir-O-Line, it was developed and is manufactured by Prodelin, Inc. as a high power radio frequency transmisson system, with a service record of several decades. The cable consists of a central conductor continuously supported by six high density polyethylene tubes inside a metal sheath, which operates as a GITL with either nitrogen or SF/sub 6/ as the filling medium. A rough analysis of the dielectric geometry concluded that its breakdown strength might be improved over that of the open coaxial conductor configuration. A series of breakdown tests was performed on the smaller range of commercially available sizes. The results confirmed the expected behavior patterns, but did not fully explore the upper units of performance due to occasional tube separations in the samples tested. The potential voltage ratings of the larger available sizes were estimated and found to be from 69 kV to 138 kV for a 3-inch O.D. size, and from 138 kV to 230 kV for a 6-inch O.D. size. There is considerable flexibility in the design of the conductor due to the continuous support of the dielectric tubes. In …
