The purpose of the ARC78 forecasts and the ways in which they differ from those in the ARC77 are discussed. In a preliminary overview of the projection process, the relationship between energy prices, supply, and demand is addressed. Topics treated in detail include a description of energy-economic interactions, assumptions regarding world oil prices, and energy modeling in the long term beyond 1995. Subsequent sections present the general approach and methodology underlying the forecasts, and define and describe the alternative projection series and their associated assumptions. Short-term forecasting, midterm forecasting, long-term forecasting of petroleum, coal, and gas supplies are included. The role of nuclear power as an energy source is also discussed.

One of the possible options for generating electrical energy from ocean thermal gradients requires the use of a floating offshore platform. The platform would contain all OTEC (Ocean Thermal Energy Conversion) systems and power cycle components and consist of the hull, seawater, station-keeping, platform service, and mission support subsystems. It would be stationed at one of the designated OTEC sites, and would transmit the generated electricity to the shore power networks by means of an electrical transmission cable. The objective of the present study is to investigate the station-keeping subsystem (SKSS) requirements and develop preliminary SKSS designs for the two Modular Experiment Plant (MEP) candidates of 10/40 MW/sub e/ capacity for deployment at a specific site. The two MEP hull candidates are a Barge type platform and a Spar shaped hull with external heat exchangers. The specific site assigned for this study is Puerto Rico. The preliminary SKSS designs are developed for both platforms as follows: (1) an 8-leg spread catenary mooring system for the Spar, and (2) a 12-leg spread catenary mooring system for the Barge. Applicability of these designs to larger capacity commercial OTEC platforms is also investigated.

This volume presents the results of the first phase of the Station Keeping Subsystem (SKSS) design study for 40 MW/sub e/ capacity Modular Experiment OTEC Platforms. The objectives of the study were: (1) establishment of basic design requirements; (2) verification of technical feasibility of SKSS designs; (3) identification of merits and demerits; (4) estimates of sizes for major components; (5) estimates of life cycle costs; (6) deployment scenarios and time/cost/risk assessments; (7) maintenance/repair and replacement scenarios; (8) identifications of interface with other OTEC subsystems; (9) recommendations for and major problems in preliminary design; and (10) applicability of concepts to commercial plant SKSS designs. A brief site suitability study was performed with the objective of determining the best possible location at the Punta Tuna (Puerto Rico) site from the standpoint of anchoring. This involved studying the vicinity of the initial location in relation to the prevailing bottom slopes and distances from shore. All subsequent studies were performed for the final selected site. The two baseline OTEC platforms were the APL BARGE and the G and C SPAR. The results of the study are presented in detail. The overall objective of developing two conceptual designs for each of the two baseline OTEC …

This volume of the report presents the results of the third through the sixth tasks of the Station Keeping Subsystem (SKSS) design studies for 10/40 MW/sub e/ capacity OTEC Modular Experiment platforms (MEP). Tasks 3 through 6 are: (3) complete preliminary designs for one SKSS for each of the two platforms (SPAR and BARGE); (4) development and testing recommendations for the MEP SKSS; (5) cost-time analysis; and (6) commercial plant recommendations. The overall conclusions and recommendations for the modular, as well as the commercial, OTEC platform station keeping subsystems are delineated. The basic design assumptions made during the process, the technical approach followed, and the results of design iterations, reliability and performance analyses are given. A complete description of the preliminary design SKSS concept is presented. The summary cost estimates for each of the alternative SKSS concepts considered are presented and a time schedule for the recommended concept is provided. The effects of varying some of the important parameters used in SKSS design on the performance and cost of the mooring system are investigated and results presented. The tests required and other developmental recommendations in order to verify and confirm the basic design assumptions are discussed. Finally, the experience gained …

The objective of the small-scale group of tests is to demonstrate that sodium will drain from the surface of the fire suppression deck into the catch pan without interference during a spill event, and to demonstrate that burning is terminated following the spill event by the accumulation of combustion products inside the drain pipes. The results of this series of tests will be used to validate the catch pan fire suppression deck design concept based on the criteria that sodium will drain freely from the surface of the fire suppression deck and that burning is terminated in an acceptably short time (less than or equal to 36 h). The objective of the large-scale group of tests is to provide experimental data on the consequences of sodium spills using prototypic leak rates and to demonstrate the effectiveness of a large-scale fire suppression Q-deck assembly.

Integral experiments performed at the Institute for Reactor Development at Juelich, West Germany, have raised doubts about the adequacy of current nuclear data and calculational methods in predicting neutron multiplication and leakage from beryllium assemblies bombarded with 14-MeV neutrons. Experimental values of inferred neutron multiplication were reported to be less than calculated values by approx. 25%. We have performed calculations of the experiments using the TART Monte Carlo code. The ratio of measured leakage multiplication to our calculated leakage multiplication is 0.85 for 8-cm-thick beryllium and 0.99 for 12-cm-thick beryllium. However, much uncertainty exists in the procedure leading to the stated experiment values of apparent multiplication. We also performed calculations for a series of experiments done at LLNL from 1955 to 1956. A 14-MeV neutron source was placed in the center of a cylindrical beryllium assembly 8 in. in radius and 24 in. in height. The beryllium assembly was encased in an aluminum can surrounded by a manganese bath. The ratio of experimental to calculated neutron leakage multiplication is 0.88. Much uncertainty exists in both series of experiments.

The papers included in this progress report summarize some significant developments in understanding the South Atlantic Bight. Some of the results are summarized as follows: Onslow Bay flushing rates can be determined using a model based on an exponential dilution model; eddy induced nitrate flux accounts for most input of new nitrogen into shelf waters; and tarballs in the Gulf Stream are not transported to the nearshore because of an apparent inner shelf density front.

Progress is reported on research conducted from June, 1979 to May, 1980 on various oceanographic aspects of the South Atlantic Bight. Research topics included: (1) A flashing model of Onslow Bay, North Carolina based on intrusion volumes; (2) A description of a bottom intrusion in Onslow Bay, North Carolina; (3) Detailed observations of a Gulf Stream spin-off eddy on the Georgia continental shelf; (4) Pelagic tar of Georgia and Florida; (5) A surface diaton bloom in response to eddy-forced upwelling; and (6) Hydrographic observations off Savannah and Brunswick, Georgia.

Long-lived isotopes in nuclear waste can have the greatest impact on man and the environment because of the integrated dose over a long time period. Many long-lived radioactive isotopes are present in the waste at Savannah River Plant. Actinide elements make up a significant portion of these isotopes. But when the waste is incorporated into a glass waste form, the actinides are converted to chemically stable oxide species that are released at extremely low and controlled rates, even after the waste form has degraded. Because of their different chemistry, radioactive isotopes of carbon, technetium, and iodine could be released at a significantly higher rate. To establish the potential hazard from these isotopes, their concentration in waste forms for final disposal must be known. The concentrations of C-14 and T{sub c}-99 in SRP waste were previously estimated. Additional analytical data has now been obtained for I-129 in H-Area soluble waste to estimate its concentration in SRP waste. Because of the nature of processes at SRP, most of the I-129 in the waste is in the H-Area waste tanks.
