Analysis of the heat transfer to hydrocarbon mixtures from geothermal brines using a sieve tray column

Description: In order to design geothermal direct contact binary cycle power plants it is necessary to develop design tools to size the direct contactor. Of particular importance is the design of the working fluid preheater. For sieve tray columns a method is presented which has been successfully used when the working fluid is a pure fluid. It is shown here to be equally successful when applied to fluid mixtures. Further, it is shown that when changing the working fluid mixture that column internals must be… more

Comparison of steam-generator liquid holdup and core uncovery in two facilities of differing scale

Description: This paper reports on Run SB-CL-05, a test similar to Semiscale Run S-UT-8. The test results show that the core was uncovered briefly during the accident and that the rods overheated at certain core locations. Liquid holdup on the upflow side of the steam-generator tubes was observed. After the loop seal cleared, the core refilled and the rods cooled. These behaviors were similar to those observed in the Semiscale run. The Large-Scale Test Facility (LSTF) Run SB-CL-06 is a counterpart test to S… more

Comparison of a TRAC calculation to the data from LSTF run SB-CL-05

Description: Run SB-CL-05 is a 5% break in the side of the cold leg. The test results show that the core was uncovered briefly and that the rods overheated at certain core locations. Liquid holdup on the upflow side of the steam generator tubes was observed. When the loop seal cleared, the core refilled and the rods cooled. The TRAC results are in reasonable agreement with the test data, meaning that TRAC correctly predicted the major trends and phenomena. TRAC predicted the core uncovery, the resulting rod… more

Summary of core damage frequency from internal initiators: Peach Bottom

Description: Probabilistic risk assessments (PRA) based on internal initiators are being conducted on a number of reference plants in order to provide the Nuclear Regulatory Commission (NRC) with updated information about light water reactor risk. The results of these analyses will be used by the NRC to prepare NUREG-1150 which will examine the NRC's current perception of risk. Peach Bottom has been chosen as one of the reference plants.

Fusion power demonstration - a baseline for the mirror engineering test reactor

Description: Developing a definition of an engineering test reactor (ETR) is a current goal of the Office of Fusion Energy (OFE). As a baseline for the mirror ETR, the Fusion Power Demonstration (FPD) concept has been pursued at Lawrence Livermore National Laboratory (LLNL) in cooperation with Grumman Aerospace, TRW, and the Idaho National Engineering Laboratory. Envisioned as an intermediate step to fusion power applications, the FPD would achieve DT ignition in the central cell, after which blankets and p… more

Fusion-breeder-reactor design studies

Description: Studies of the technical and economic feasibility of producing fissile fuel in tandem mirrors and in tokamaks for use in fission reactors are presented. Fission-suppressed fusion breeders promise unusually good safety features and can provide make-up fuel for 11 to 18 LWRs of equal nuclear power depending on the fuel cycle. The increased revenues from sales of both electricity and fissile material might allow the commercial application of fusion technology significantly earlier than would be po… more

Three equipment concepts for the Fusion Engineering Device

Description: Maintenance equipment which is needed to remotely handle fusion device components is being conceptually developed for the Fusion Engineering Design Center. This will test the assumption that these equipment needs can be satisfied by present technology. In addition, the development of equipment conceptual designs will allow for cost estimates which have a much higher degree of certainty. Accurate equipment costs will be useful for assessments which trade off gains in availability as a function o… more

Behavior of temperature and concentration of shallow groundwater in the Raft River Geothermal Area

Description: A moderate-temperature (140/sup 0/C) geothermal power plant demonstration, sponsored by the Department of Energy, is currently under development in South Central Idaho. Environmental concerns about the quality of the local shallow groundwater prompted a modeling study. Simulation results (1) suggest significant thermal and quality levels within the 30-year projected plant operation and (2) makes obvious the importance of understanding the interconnected hydraulic systems.

Heat pumps coupled to geothermal resources can provide economical process heat

Description: Temperatures available from geothermal resources are frequently too low to serve the needs of many process industries. Heat pumps can be used to boost the temperatures by moderate amounts at an economical cost. A number of potential working fluids were examined for service from 150/sup 0/F to 400/sup 0/F. Steam and R-11 were found to be the best choices. Comparison cost estimates were made for different bottom temperatures and delivery temperatures for both steam and R-11 systems. The results s… more

Calibration of a drag disc turbine transducer and a gamma beam densitometer to measure the mass flow rate in separated horizontal two-phase flow

Description: The accurate measurement of two-phase mass flow rate is very important in experiments, such as the LOFT experiment, which investigate the hypothetical Loss-of-Coolant Accident (LOCA). This paper analyzes experiments designed to determine the behavior of a LOFT free field drag disc turbine transducer (DTT) and a LOFT-type three-beam gamma densitometer in a steady state, horizontal high pressure steam-water flow. The experiments were conducted in a mass flow and void fraction range where a variet… more

Effects of Controlled Disturbance on Ferruginous Hawks as May Occur During Geothermal Energy Development

Description: The impacts on the ferruginous hawk of treatments designed to simulate those encountered during geothermal developments were assessed at the Raft River Geothermal Test Site. The objective of the study was to ascertain the tolerance limits of the disturbance-sensitive hawks to human- and development-related activities. Various impact treatments were imposed on 10 nests during the 1978 nesting season and 13 nests during 1979. Three nests were deserted in 1978 and four in 1979; treatment nests tha… more

Gas Reactor In-Pile Safety Test Project (GRIST-2)

Description: Although out-of-pile tests may be expected to confirm individual phenomena models in core disruptive accident analysis codes, only in-pile tests are capable of verifying the extremely complex integrated model effects within the appropriate time phase for these accidents. For this reason, the GRIST-2 project, the purpose of which is to design and construct an in-pile helium loop capable of transient safety testing in the TREAT facility in Idaho, forms a cornerstone of the US GCFR safety program.… more

General Criteria for Radioactive Waste Disposal

Description: Techniques are being developed for conversion of radioactive wastes to solids and their placement into repositories. Criteria for such disposal are needed to assure protection of the biosphere. The ALARA (as low as reasonably achievable) principle should be applicable at all times during the disposal period. Radioactive wastes can be categorized into three classes, depending on the activity. Three approaches were developed for judging the adequacy of disposal concepts: acceptable risk, ore body… more

Siting Criteria as a Function of Sensitivity of Nesting Ferruginous Hawks to Geothermal Development

Description: The ferruginous hawk has been studied over a number of years in the Raft River Valley area of south-central Idaho and consequently its population densities and dynamics are known. The ferruginous hawk is to be used as a barometer to the effects of human disturbance as might be found during geothermal development. It was proposed to determine what sort of buffer zones need to be established around the species to be compatible with the concepts of multiple use, and accumulate information and base… more
