Power plant reject heat utilization: an assessment of the potential for wide-scale implementation

Description: An assessment of the relative economic and heat utilization merits of plant reject heat utilization systems was made in an effort to indicate those technologies that show the greatest potential for wide-scale implementation in the power generating industry. The heat utilization systems were designed to accommodate the yearly cooling needs of a 1000-MW(e) power plant. Thus, for the purposes of this study, it was assumed that these systems replaced the cooling tower as the primary condenser cooli… more

Energy study of railroad freight transportation. Volume 4. Efficiency improvements and industry future

Description: Railroad equipment and operating practices were largely developed in an era during which the price of fuel was a relatively minor part of the cost of railroad operations; however, fuel has now become a scarce and expensive resource. Although many opportunities exist for installing new equipment and operating practices that will result in fuel conservation, cost and market factors can promote or retard the rate at which changes are adopted, and only limited technology may be available for use in… more

Drift-modeling and monitoring comparisons. [Drift from power plant cooling towers]

Description: Congress is looking into the conglomeration of nuclear reactors into energy centers of limited area. Drift from cooling towers can corrode and damage structures in the immediate vicinity of the towers, cause a public nuisance if located near parking lots or high-density traffic areas, and endanger local vegetation. The estimation of salt deposition has relied primarily on predictions from a variety of models, with very few direct measurements. One of the major efforts in our program is to evalu… more

Modeling Water Management in Polymer-Electrolyte Fuel Cells

Description: Fuel cells may become the energy-delivery devices of the 21st century with realization of a carbon-neutral energy economy. Although there are many types of fuel cells, polymerelectrolyte fuel cells (PEFCs) are receiving the most attention for automotive and small stationary applications. In a PEFC, hydrogen and oxygen are combined electrochemically to produce water, electricity, and waste heat. During the operation of a PEFC, many interrelated and complex phenomena occur. These processes includ… more

Nuclear Safeguards Considerations For The Pebble Bed Modular Reactor (PBMR)

Description: High temperature reactors (HTRs) have been considered since the 1940s, and have been constructed and demonstrated in the United Kingdom (Dragon), United States (Peach Bottom and Fort Saint Vrain), Japan (HTTR), Germany (AVR and THTR-300), and have been the subject of conceptual studies in Russia (VGM). The attraction to these reactors is that they can use a variety of reactor fuels, including abundant thorium, which upon reprocessing of the spent fuel can produce fissile U-233. Hence, they coul… more
