A New Approach to Activated Sludge Plant Design
Activated sludge plants are designed on the basis of stationary tests at laboratory scale for constant organic loads and constant input flows. From these tests the kinetic parameters are...
Oil Spill Detection by NOAA/AVHRR on Persian Gulf
An area of oil spills on the Persian Gulf was detected by the thermal-infrared channels of Advanced Very High Resolution Radiometer (AVHRR) on NOAA-7. AVHRR gives the temperatures of the...
Modeling the Fate and Transport of Biocides in Estuarine Power Plant Cooling Water Discharges
This paper presents a framework with examples for understanding the fate and transport of cooling system discharges into estuaries through the use of modeling. The modeling of biofouling...
Zooplankton Entrainment Evaluation in a Power Plant Station
The impact study on the Setubal thermal plant included an evaluation of the plant's effects on zooplankton in the outlet area. After entrainment in the cooling system there...
Hydraulic Fill Dam Made Earthquake Resistant
San Pablo Dam, near the San Andreas fault, constructed in 1919-21 by hydraulic fill methods, was found to be susceptible in places to liquefaction under seismic loading. The dam has been...
A Space Age Test Center
The Air Force's Aeropropulsion System Test Facility (ASTF) is the most expensive project the Air Force has ever built. Its massive heaters, coolers and compressors will treat...
Longitudinal Prestressed Piping for District Heating
The design of recently installed hot water district heating systems in the United States is based on similar systems developed in Europe. Longitudinal prestressing is used in the design...
Application of Water Budget to Seepage Loss Estimation
The seepage loss for the emergency cooling water spray pond has been calculated by performing a water balance study for the pond. A field test of the spray pond was performed to estimate...
Simulation of Far-Field Thermal Effects from Browns Ferry Nuclear Plant
A computer model was used to evaluate the far-field effects of revised thermal discharge limitations at the Tennessee Valley Authority's Browns Ferry Nuclear Plant (BFN)....
The Microcomputer as an Intelligent Workstation in Large Scale Hydrologic Modeling
In an effort to improve the efficiency of the hydrologic modeling activities of the Maryland State Highway Administration (MSHA), a cooperative project between MSHA, the Federal Highway...
Hydrothermal Model Study of Stratified Flow in a Power Plant Cooling Water Recycle/Intake Canal: Reynolds and Densimetric Froude Number Effects
During the winter of 1983-1984, the control of frazil ice at the trash tracks using pneumatic air guns was evaluated at Danskammer Point Generating Station. This paper presents a brief...
Frazil Ice Control Using Air Guns
The design of the J. H. Campbell, Unit 3, Cooling Water Intake in the late 1970's used some new ideas and concepts in response to a strong concern for fish protection at a...
Unique Utilization of a Physical Model to Develop a Construction Sequence of a Major Cofferdam
Lock and Dam 26 Replacement is being constructed on the Mississippi River about 2 miles downstream of the existing Locks and Dam No. 26 at Alton, Illinois. This paper discusses the unique...
Make-up and Blowdown of a Cooling Pond
A mathematical model was developed to simulate the operation of a recirculating cooling pond for a planned nuclear power plant in the Midwest. The objective of the pond operation is to...
SWRRB.80: A Basin Scale Model for Microcomputers
The SWRRB (Simulator for Water Resources on Rural Basins) model was developed by the USDA Agricultural Research Service to simulate the daily stream flow, and sediment loads from agricultural...
Guideway and Conductor Rail Heating for a Winter Environment
The power and signal conducting rails are maintained using self-limiting heat trace cable in combination with an inherently protected rail. The cable's high inrush power along...
Uplift Capacity of Helical Anchors in Clay and Silt
The results of a study on the uplift capacity of helical anchors in clay and silt are presented. Full-scale field tests and one-quarter scale laboratory tests were conducted in each soil...
A Summary of the Seismic Qualification Utilities Group (SQUG) Program
In December of 1980, the Nuclear Regulatory Commission (NRC) initiated Unresolved Safety Issue (USI) A-46 to address the question of the seismic adequacy of equipment in 49 operating nuclear...
Seismic Design-Qualification of Non-Safety Related Items in Safety Related Envelope
This presentation pertains to Seismic Design-Qualification for those portions of structures, systems, or components in a Nuclear Plant whose continued function is not required but whose...
Strength of Soils in Terms of Effective Stress
The factors that determine soil strength, such as amount of confinement, density, particle size distribution, mineral friction, aging, particle crushing, and others, produce their effects...
