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...
Biofouling Control of Water Intake Structures
Biofouling of water intakes can affect condenser performance and availability. This paper discusses four biofouling control technologies: thermal backwash, antifouling coatings, chlorination,...
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...
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...
Insulative Lightweight Concrete for Building Walls
Research is currently being conducted to develop a portland cement concrete for use in low-rise building walls that will combine the structural, thermal insulating, and heat storage capacity...
Analysis of Cracking of I79 Bridge at Neville Island
A large crack was discovered to form in a girder of the I-79 Glenfield Bridge over the back channel of the Ohio River near Pittsburgh on January 28, 1977. A section of the girder containing...
A Summary of the Seismic Qualification Utilities Group (SQUG) Program
