Parts that are manufactured with diamond tools on precision machines typically exhibit high-quality surfaces and contours; however, most materials that are diamond turned easily are also relatively soft and damage easily. Therefore, a noncontact, rotary inspection machine was developed. This machine utilizes a focused beam from a laser interferometer to measure variations in the surfaces of the reflective, spherical test parts used to characterize precision machines. Digital output data from the laser display is converted to an analog signal which is available for additional processing to provide contour and/or surface texture information.

A canonical resolution of the multiplicity problem was proven for U(3) and this resolution is extended to a determination of all U(n) tensor operators characterized by maximal null space. 9 references.

The relativistic multigroup diffusion equations describing superthermal electron transport in laser fusion plasmas were derived in an earlier UCRL. A successful numerical scheme based on these equations which is now being used to model laser fusion experiments is described.

A mechanical model for the emplacement pipe system is developed. The model is then employed to determine the force applied to the surface collar of the emplacement pipe, the pipe-stemming load, and the stress along the emplacement pipe as a function of stemming height. These results are presented as integrals and a method for their numerical integration is given.

A retrofit solar water-heating system has been operating for the past two years in a three-story apartment building at Drexel University. The system employs two conventional collector banks (9 PPG collectors) mounted at the latitude angle for Philadelphia of 40 deg from the horizontal and two double-exposure collectors (DEC's) mounted vertically in mirrored enclosures. The relative performance of the conventional and double-exposure collectors has been monitored with an instrumentation system which was developed and installed in the basement of the apartment building. The DEC units have been found to provide from two to four times as much useful heat output per panel area than the PPG collectors. The higher relative performance values occur on clear winter days whereas lower relative performance values are found on clear summer days and generally overcast days. A cost analysis for a DEC unit relative to a conventional collector has also been performed. In the Philadelphia area the DEC units with their mirror enclosures would cost approximately 1.7 times as much per panel area as conventional collectors. Since the DEC units provide two to four times as much useful heat output, they are a cost-effective choice for flat or gently sloping roofs for which they …

The inertia and friction-welding processes were evaluated for joining aluminum alloy 1100-H14 and Type 316 vacuum-induction melted, vacuum-arc remelted (VIM VAR) stainless steel. While both processes consistently produced joints in which the strength exceeded the strength of the aluminum base metal, 100 percent bonding was not reliably achieved with inertia welding. The deficiency points out the need for development of nondestructive testing techniques for this type of joint. Additionally, solid-state volume diffusion did not appear to be a satisfactory explanation for the inertia and friction-welding bonding mechanism.

Four different models of the migration process have been reviewed to determine their suitability as a working model. While there are several common factors in the models additional factors are included to account for several possible effects. The detail of each model leads to a certain degree of difficulty in applying the model to the problem at hand. One model predicts that inclusions smaller than 0.1 mm dimension probably will not migrate. The other models do not consider size as a factor. Thermal diffusion (Soret effect) is considered insignificant in three models, while in the fourth model it is added to the concentration diffusion term. The following conclusions are made: (1) Temperature is the most significant parameter in all models and must be known as a function of time, and distance from the canister. (2) All four models predict about the same migration velocity for a given set of conditions. For 100/sup 0/C and 1/sup 0/C/cm thermal gradient, the individual values are 3.0, 4.8, 5.6 and 6.4 mm/y. (3) The diffusion of ions through the brine inclusions is the rate controlling mechanism. (4) The difference between the thermal gradients in the liquid and in the solid should always be considered, …

When canisters containing radwastes are emplaced in a repository the heat produced by the decaying radwaste will cause moderate thermal gradients to develop which will cause the brine present in a halite medium (salt deposits) to accumulate around the canister. Four different models of the migration process have been reviewed to determine their suitability as a working model. One model predicts that inclusions smaller than 0.1 mm dimension probably will not migrate. The other models do not consider size as a factor. Thermal diffusion (Soret effect) is considered insignificant in three models, while in the fourth model it is added to the concentration diffusion term.

Coatings for laser fusion targets have been deposited in an inductively coupled discharge device by plasma polymerization. Two feed gases were used: perfluoro-2-butene, which produced a fluorocarbon coating (CF/sub 1/ /sub 3/) with a density of 1.8 g/cc, and trans-2-butene which produced a hydrocarbon coating (CH/sub 1/ /sub 3/) with a density of 1.0 g/cc. Uniform pin-hole free films have been deposited to a thickness of up to 30 ..mu..m of fluorocarbon and up to 110 ..mu..m of hydrocarbon. The effect of process variables on surface smoothness has been investigated. The basic defect in the coating has been found to result from shadowing by a small surface irregularity in an anisotropic coating flux.

An evaluation of the methodology of the Resource Allocation's Model (RAM), developed to assist in developing an efficient research, development, and demonstration program for energy conserving technologies in the residential and commercial sectors, is presented. This evaluation begins by classifying the technologies according to the markets in which they will compete once they are commercialized. Within each market group, the probable costs of the new technologies are compared to the cost of the competitive conventional product. This information is used to calculate the expected energy savings of each portfolio of projects. Portfolios are then ranked in order of increasing energy savings, and estimates made of the value of various levels of funded research in each functional use area. Finally, successful portfolios in different market groups are compared in a similar manner in order to identify the most efficient comprehensive portfolio at each research funding level. Section 2 describes the original methodology and presents some of the modifications that were made during this task. Section 3 discusses the specific changes that were made, including improvements to the model as well as the development of more reliable data. The revised methodology is then applied to one market group to demonstrate its capabilities …

Thick film coatings of beryllium, needed for the low-Z ablator layer in proposed laser fusion targets, have been prepared using high rate magnetron rf sputtering. The requirements for these Be coatings include thicknesses from 5 to 50 ..mu..m, complete freedom from surface defects, and an average surface roughness of 100 nm or less. We have sputtered very smooth, dense, thick Be films with surface roughness less than 100 nm. X-ray diffraction analysis of impurity doped films indicates an amorphous-like structure. Impurity stabilized amorphous Be with smooth surfaces is reported on both cooled copper and higher temperature glass substrates. The sputtering parameters (substrate temperature, deposition rate, argon pressure, and impurity gas levels) affecting surface roughness and film structure are discussed in terms of SEM, AES, and x-ray diffraction results.

At the request of the U.S. Nuclear Regulatory Commission (NRC), the Pacific Northwest Laboratory (PNL), operated by Battelle Memorial Institute for the Department of Energy, conducted a brief study to identify the incremental cost for implementing the US/IAEA safeguards treaty agreement. The purpose of the study was to develop an estimate of the cost impact to eligible NRC licensees for complying with the proposed Part 75 of Title 10, Code of Federal Regulations (10 CFR 75), the rule which will implement the treaty. The study was conducted using cost estimates from several eligible licensees who will be affected by the agreement and from cost analyses by PNL staff. A survey instrument was developed and sent to 25 NRC licensees, some of whom had more than one licensed facility. Their responses were obtained primarily by telephone after they had reviewed the survey insttument and a list of assumptions. The primary information received from the licensees was the incremental cost to their particular facility in the form of manpower, dollars or both. In summary, the one-time cost to all eligible NRC licensees to implement 10 CFR 75 is estimated by PNL to range from $1.9 to $7.2 millions. The annual cost to …

This report defines the analytical framework for, and presents the results of, a study to determine the macroeconomic effects of increased market penetration of solar energy technologies over the 1977-2000 time period. For the purposes of this document, solar technologies are defined as wind, photovoltaics, ocean thermal electric (OTEC), small-scale (non-utility) hydroelectric and all solar active and passive thermal technologies. This research has been undertaken in support of the National Plan to Accelerate Commercialization (NPAC) of Solar Energy. The capital and operating requirements for three market penetration levels are first determined; the effects of these requirements on economic performance are then estimated using the Hudson-Jorgenson Energy/Economic Model. The analytical design, computational methods, data sources, assumptions and scenario configurations for this analysis are defined in detail. The results of the analysis of the economic impact of solar energy are presented in detail, and the implications of these results are discussed. Appendix A explains the methodology for transforming investment to capital stocks. Appendix B, which is provided in a separate volume, describes the Hudson-Jorgenson Model in greater detail. (WHK)

The Hudson-Jorgenson Energy/Economic Model - formally known as the Long Term Interindustry Transactions Model (LITM) - is an econometric model of the structure of the US economy. LITM integrates two separate models into one integrated system. These models are the Macroeconomic Model, a growth model incorporating the underlying trends of economic development, and the Interindustry Model, an endogenous coefficient input-output model of the structure of the economy incorporating patterns of expenditure, prices, and production on a sectoral basis. LITM emphasizes the energy system and its role within the economy. Applications of LITM have, therefore, focused on energy, the effect of energy changes on the economy, and the effect of econometric changes on the energy system. In addition, LITM can be used as framework for long term economic projection and structural analysis.

The interactive effects of elevated temperatures and nutrient enrichment on periphyton communities on glass slides were studied for one year in the Flowing Streams Laboratory, operated by Savannah River Laboratory (SRL) for the Department of Energy (Figure 1). Water from a South Carolina stream called Upper Three Runs, characterized by low pH and low nutrient concentrations and with intermittent swamp drainage, was used.
