Geothermal power production: accidental fluid releases, waste disposal, and water use

Description: Environmental problems related to the use and disposal of fluids can accompany the operation of geothermal power plants using hot water resources (temperature > 150/sup 0/C). More than 100 kg of fluids must be extracted, processed, and disposed for each kW.h of electricity generated from a facility relying on a geothermal reservoir with fluids of 150/sup 0/C. The low thermal efficiencies of geothermal power plants result in large requirements for cooling water - over 7.4 x 10/sup 4/ m/sup 3//MW… more

Removal of silica from Raft River geothermal water

Description: Lack of sufficient quantities of clean surface or near-surface water at Raft River for cooling purposes dictates that cooled geothermal fluid, effluent from the Raft River 5 MW(e) Pilot Power Plant, must also be used as condenser coolant. Prior testing revealed that a water-treatment system would be required to reduce silica and calcium concentrations of the cooling fluid. The water-treatment system specified was to use dolomitic lime for both pH adjustment and source of magnesium. The dolomiti… more

Population dose commitments due to radioactive releases from nuclear-power-plant sites in 1978

Description: Population radiation dose commitments have been estimated from reported radionuclide releases from commercial power reactors operating during 1978. Fifty-year dose commitments from a one-year exposure were calculated from both liquid and atmospheric releases for four population groups (infant, child, teen-ager and adult) residing between 2 and 80 km from each site. This report tabulates the results of these calculations, showing the dose commitments for both liquid and airborne pathways for eac… more

Analysis of costs and benefits for eight powerplant productivity improvement projects. Project 1, Task 3. Final report

Description: In 1976, DOE (FEA) sponsored the development of a systematic methodology for the identification and analysis of candidate projects which a utility might undertake to improve baseload unit reliability. This methodology also enabled the user to estimate a project's effect on the future performance of the unit. A project was sponsored in Illinois to demonstrate the methodology and to encourage increased power plant productivity in the state. A total of 8 improvement projects were conducted and ana… more

Nuclear proliferation and civilian nuclear power. Report of the Nonproliferation Alternative Systems Assessment Program. Volume II. Proliferation resistance

Description: The purpose of this volume is limited to an assessment of the relative effects that particular choices of nuclear-power systems, for whatever reasons, may have on the possible spread of nuclear-weapons capabilities. This volume addresses the concern that non-nuclear-weapons states may be able to initiate efforts to acquire or to improve nuclear-weapons capabilities through civilian nuclear-power programs; it also addresses the concern that subnational groups may obtain and abuse the nuclear mat… more

High-Temperature-Turbine Technology Program: Phase II. Technology test and support studies. Design and development of the liquid-fueled high-temperature combustor for the Turbine Spool Technology Rig

Description: The concept selected by Curtiss-Wright for this DOE sponsored High Temperature Turbine Technology (HTTT) Program utilizes transpiration air-cooling of the turbine subsystem airfoils. With moderate quantities of cooling air, this method of cooling has been demonstrated to be effective in a 2600 to 3000/sup 0/F gas stream. Test results show that transpiration air-cooling also protects turbine components from the aggressive environment produced by the combustion of coal-derived fuels. A new single… more

Site-specific analysis of hybrid geothermal/fossil power plants

Description: A preliminary economic analysis of a hybrid geothermal/coal power plant was completed for four geothermal resource areas: Roosevelt Hot Springs, Coso Hot Springs, East Mesa, and Long Valley. A hybrid plant would be economically viable at Roosevelt Hot Springs and somewhat less so at Coso Hot Springs. East Mesa and Long Valley show no economic promise. A well-designed hybrid plant could use geothermal energy for boiler feedwater heating, auxiliary power, auxiliary heating, and cooling water. Con… more

Seismic and layout design for a tank-type fast reactor

Description: Hitachi Ltd. of Japan, with the assistance of the Bechtel Group, Inc. and the General Electric Company of the US, initiated a conceptual design study of a compact tank-type LMFBR. The Bechtel work concentrated on layout of the nuclear island (NI), and its orientation with respect to the Control (CB) and Turbine (TGB) Buildings. This joint effort was carried out during 1982 and 1983 in four steps. Each step produced improvements in the design and reduced the plant size and cost. This paper descr… more

Release of fission products from irradiated SRP fuels at elevated temperature. Data report on the first stage of the SRP source term study

Description: For a sound evaluation of the consequences of a hypothetical nuclear reactor accident, a knowledge of the extent of fission product release from the fuel at anticipated temperatures and atmosphere conditions is required. Measurements of fission product release have been performed with a variety of nuclear fuels under various conditions of temperature and atmosphere. While the use of data obtained on fuels similar to the fuel of interest may provide a reasonable estimate of release fractions, pr… more
