Environmental and Economic Comparison of Cooling System Designs for Steam-electric Power Plants

The selection of waste heat rejection systems for steam-electric power plants involves a trade-off among environmental, energy and water conservation, and economic factors. This study compares four general types of cooling systems on the basis of these factors. The cooling systems chosen for study are: once-through systems including surface canals and submerged multiport diffusers; shallow closed cycle cooling ponds; mechanical and natural draft evaporative cooling towers; and mechanical draft dry towers. The cooling system comparison involves, first, an optimization of each cooling system and then a comparison among optimal systems. Comparison is made for an 800 MWe fossil unit and a 1200 MWe nuclear unit located at a hypothetical midwestern river site. A set of models has been developed to optimize the components of each cooling system based on the local meteorological and hydrological conditions at the site in accordance with a fixed demand, scalable plant concept. This concept allows one to compare the costs of producing the same net power from each plant/cooling system. Base case economic parameters were used to evaluate the optimum system for each of the four general cooling systems followed by a sensitivity study for each parameter. Comparison of energy and water consumption follows from the results of the performance model, while comparison of environmental impacts is mostly qualitative. Some quantitative modelling was performed for the environmental effects of thermal discharges from once-through systems, fogging from wet cooling towers and water consumption from the ponds, wet towers and once-through. The results of the optimization models of each of the systems are compared on the basis of: performance - discrete distributions of environmental conditions and transient simulation; economics - using base case scenarios and sensitivity values to arrive at costs expressed in terms of production costs, annualized costs and present value costs; energy and water consumption; and environmental effects. The once-through systems were found to be the least expensive of the four systems, the most energy efficient, but potentially the most environmentally damaging. On the other extreme, dry cooling towers are the most environmentally sound while being the most expensive and least energy efficient. Finally, the results of the economic optimization are compared with results from previous comparative studies.

Teacher Learning in Language Teaching

This book introduces a new field of educational research called teacher learning, as it applies to the teaching of languages. Up until recently, the study of second language teacher education has focused mainly on the knowledge base and specific skills needed for effective teaching. This book invites us to look at teacher education from a fresh point of view, through an exploration of the thinking and learning processes of individuals as they learn to teach. Seventeen original articles, based on studies done in North America, Europe, Asia, and Australia, provide examples of pioneering research into the ways that individuals learn to teach languages, and the roles that previous experience, social context, and professional training play in the process. The collection thus helps establish a research base for this newly developing field.

Developing Competent Teachers

Approaches to Professional Competence in Teacher Education

The aim of this book is to explore the implications of different ways of thinking about the professional competences of teachers. It does so through case studies of competence frameworks used in a number of teacher education contexts - and, for comparative insights, in social work, nursing and police training. The book arose out of the work of a national working group under the auspices of the ESRC. The intended readership is all involved in teacher education: in particular, Higher Education tutors; mentors and senior staff in schools supporting school-based ITE schemes; INSET providers and LEA advisory staff working in the area of NQT recruitment and staff development.
