An in-progress assessment of nutrient chemical data (phosphate, nitrate, nitrite, and silicate) from four potential OTEC sites (Puerto Rico, the Gulf of Mexico, Hawaii, and the South Atlantic) show reasonable comparison with archival data. At this time sufficient data is available only at the Tampa site (Gulf of Mexico) to discern seasonal variations which show an influx of nutrient-rich water in February, which decreases with time to a minimum in December. Results show a greater potential for stimulation of primary productivity at the Hawaii site than in the northern Gulf of Mexico due to the discharge of the cold water pipe into the photic zone.

This report is about the state-of-the-art of the anaerobic fermentation processes for the conversion of cellulosic waste materials to chemicals and fuels.

This is an interim report of a study to establish a risk measure for radioactive waste repositories and to generate radiological performance objectives. The problem of regulating radioactive waste repositories is reviewed, and the difficulties associated with this activity are discussed. Risk-benefit analysis as a tool for regulation has been suggested, and its contribution is assessed. Decision analysis as a development of risk-benefit analysis is suggested as an alternative approach, in particular, employing the concept of expected utility. A utility function which describes the possible consequences of a radioactive waste repository is discussed in some detail, paying particular attention to the public concerns which must be addressable through such a function and how it is recommended to capture them. A specific utility function is developed, and its elicitation from a particular subject is described. The representation of public values in a decision-analytic approach presents some problems and these are fully discussed; recommendations are made as to appropriate methods to carry this out. The vexed question of determining an acceptable safety limit is studied and recommendations are made concerning the most suitable way to determine ''how safe is safe enough.'' Finally a brief discussion is given of how these concepts may …

The growing awareness of the hazards of chemicals in the environment has resulted in the passing of the Toxic Substances Control Act (TSCA) on Oct. 11, 1976. This paper attempts to cover some of the salient features of Public Law 94-469, EPA's approach to implementation of its provisions, and some of a chemist's perceptions of TSCA's prospects of success.

Industrial conversion in the U.S. to alternate fuels from natural gas is presently underway and is anticipated to accelerate rapidly in the next few years. Currently the prime alternate fuels are distillate and residual oils. Conversion to residual oils for high-temperature process heat applications is anticipated to result in accelerated refractory and insulation corrosion and degradation due to reactions between fuel impurities and the ceramic linings of high-temperature equipment. Analyses are presented of several generic types of refractories and fibrous insulations which were exposed to residual oil combustion products under well-controlled conditions for times ranging from hundreds to thousands of hours in a Refractory Test Facility (RTF) designed to simulate industrial process heat combustors. Results are presented for aluminosilicate refractory firebricks, mortars, and refractory fibrous insulations following exposure to domestic residual oil combustion for 500 hr at temperatures near 1375/sup 0/C (2500/sup 0/F). For all three types of refractory material, compositions with two different Al/sub 2/O/sub 3/ contents were included. The fuel oil impurities included Fe, Ca, Zn, Ni, Pb, and S in concentrations from tens to hundreds of weight ppM. Some of these impurities reacted with the refractory samples by producing a slag layer on the exposed surfaces followed …

Summary: "This study was conducted for the purpose of developing a relationship between elastic pavement deflection and pavement performance (number of traffic applications necessary to cause failure). Data for the study were taken from past studies of airfield and highway pavements. A summary of test conditions, failure criteria, and traffic type is given for each data source. A relationship was developed between elastic deflection and the number of coverages of traffic for combined airfield and highway data and for airfield data only. The relationship of wheel load and tire pressure is given, and a multiple-regression equation was determined to predict coverages as a function of wheel load, tire pressure, and deflection" (p. xi).

The process by which technology and information related to technology are transferred within industry is explored. Property rights in technology are part of the broader field of intellectual property. The general contours of legal protection for knowledge are explored. The four basic forms of intellectual property - patents, trade secrets (or know-how), trademarks, and copyrights - are covered in varying degrees of depth, depending on their relative applicability to the development of the solar industry. Once this background has been established, the legal aspects of licensing are examined. A license is a legal arrangement whereby a party (licensor) who controls the right to use an idea, invention, etc. shares the right to use the particular intellectual property with someone else (licensee). The advantages and disadvantages of licensing are described from the point of view of potential licensees and licensors. Barriers to licensing are discussed.

These step-by-step procedures enable an occasional operator to run the Site 300 Meteorological Center. The primary function of the Center is to determine the maximum weight of high explosives that can be fired at Site 300 under any given meteorological conditions. A secondary function is to supply weather data for other programs such as ARAC (Atmospheric Release Advisory Capability). Included in the primary function are radar and theodolite operations for balloon tracking; calculation of temperatures for various altitudes using Oakland weather obtained from a teletype; computer terminal operation to obtain wind directions, wind velocities, temperatures, and pressure at various altitudes; and methods to determine high-explosive weight limits for simple inversions and focus conditions using pressure-versus-altitude information obtained from the computer. General information is included such as names, telephone numbers, and addresses of maintenance personnel, additional sources of weather information, chart suppliers, balloons, spare parts, etc.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

Uni-axial seismic tests were performed on a 1/2-scale, two-dimensional model of the HTGR core consisting of 73 graphite elements in a hexagonal array. Core displacement and velocity, boundary support force, and in-core element force were measured. Behavior of the core using single-axis excitation was compared with its behavior when subjected to two-axis excitation.

The major projects undertaken include: the provision of a State Institutional Handbook, the provision of in-depth geothermal resource data, the comparison of energy sources and uses, economic data compilation for area development plans, the preparation of site-specific development plans, and the outreach program. Progress is reported on each of these projects. (MHR)

This report outlines and discusses the major Federal statutes which can act as constraints and incentives to the various types of energy resource developments and their resulting impacts. While state and local legislation and other political and institutional factors may create more immediate constraints and incentives regarding the location of energy developments, Federal legislation can supersede state and local powers and often sets a precedent for similar state legislation. This study examines institutional barriers and incentives to energy development and investigate potential management strategies for energy impacts, deals with the first layer of constraints--Federal legislation. For this discussion, constraints and incentives are the laws and resulting policies and guidelines that limit and/or encourage certain development policies and actions. These laws set parameters along several dimensions within which all development actions must occur. The dimensions, which are the sectors of the Regional Assessment Program are (1) air quality, (2) water quality, (3) bioproductivity, (4) land use, (5) economics/energy, and (6) community development (social/demographic/psychological issues). This report has been organized along the six dimensions. The characteristics of the Pacific Northwest region and of the energy development/production process are described. A general overview of the Federal legislative constraints and incentives, including some discussion …

Uni-axial seismic tests were performed on /sup 1///sub 5/-scale and /sup 1///sub 2/-scale two-dimensional models of the HTGR core consisting of 73 graphite elements in a hexagonal array. Core displacement and velocity, boundary support force, and in-core element force were measured. The test rigs were excited in two directions: across-the-flats of an element and across-the-corners. Results from the two models were compared on a normalized scale basis to check the scaling laws.

A comparative study and quantitative assessment of the impacts, costs and benefits associated with the mining, processing and transportation of coal and uranium within the western states, specifically Arizona, California, Colorado, Montana, New Mexico, Oregon, Utah, Washington and Wyoming are presented. The western states possess 49% of the US reserve coal base, 67% of the total identified reserves and 82% of the hypothetical reserves. Western coal production has increased at an average annual rate of about 22% since 1970 and should become the major US coal supplier in the 1980's. The Colorado Plateau (in Arizona, Colorado, New Mexico and Utah) and the Wyoming Basin areas account for 72% of the $15/lb U/sub 3/O/sub 8/ resources, 76% of the $30/lb, and 75% of the $50/lb resources. It is apparent that the West will serve as the major supplier of domestic US coal and uranium fuels for at least the next several decades. Impacts considered are: environmental impacts, (land, water, air quality); health effects of coal and uranium mining, processing, and transportation; risks from transportation accidents; radiological impact of coal and uranium mining; social and economic impacts; and aesthetic impacts (land, air, noise, water, biota, and man-made objects). Economic benefits are discussed.
