India's three-stage nuclear power programme involves self sustaining Thorium closed fuel cycle based reactors. It has initiated design and development of the Advanced Heavy Water Reactor (AHWR). AHWR is a 920 MW (thermal) capac- ity, heavy water moderated, boiling light water cooled in natural circulation, vertical pressure tube type nuclear reactor. It is fueled by (Th-233U)O2 pins and (Th-Pu)O2 pins and the reactivity is mainly controlled by neutron absorber rods. Some advantages of Thorium-based fuel cycle are abundance of Thorium in In- dia, closed fuel cycle, reduction of radio toxicity of waste to a lower extent, proliferation resistance (prevent or discourage the production of weapon grade material). AHWR offers clean, sustainable nuclear energy, and is one of the flagship technologies of India's nuclear programme. The physical dimensions of AHWR are very large in comparison to neutron migration length, making it susceptible to Xenon induced oscillations and flux- tilting. These undesirable oscillations are common with large nuclear reactors which, if not controlled, can pose unequal spatial distribution of power and increase the chances of fuel failure. Thus it is necessary to devise a control strategy to regulate these spatial oscillations.

Describes control systems for boilers and heat-recovery steam generators (HRSGs) in a variety of applications, from waste-to-energy plants to combined-cycle gas-turbine power stations. Basics such as methods of connecting instruments are explained, and more advanced discussions of design features of distributed control systems are also included. At every stage, emphasis is given to the interactive nature of plants and to troubleshooting and problem solving. Includes chapter summaries. The author is Fellow of the Institution of Electrical Engineers, and the Institute of Marine Engineers, and is a Senior Member of the Instrument Society of America.

Electricity, supplied reliably and affordably, is foundational to the U.S. economy and is utterly indispensable to modern society. However, emissions resulting from many forms of electricity generation create environmental risks that could have significant negative economic, security, and human health consequences. Large-scale installation of cleaner power generation has been generally hampered because greener technologies are more expensive than the technologies that currently produce most of our power. Rather than trade affordability and reliability for low emissions, is there a way to balance all three? The Power of Change: Innovation for Development and Deployment of Increasingly Clean Energy Technologies considers how to speed up innovations that would dramatically improve the performance and lower the cost of currently available technologies while also developing new advanced cleaner energy technologies. According to this report, there is an opportunity for the United States to continue to lead in the pursuit of increasingly clean, more efficient electricity through innovation in advanced technologies. The Power of Change: Innovation for Development and Deployment of Increasingly Clean Energy Technologies makes the case that America's advantagesâ€"world-class universities and national laboratories, a vibrant private sector, and innovative states, cities, and regions that are free to experiment with a variety of public policy approachesâ€"position the United States to create and lead a new clean energy revolution. This study focuses on five paths to accelerate the market adoption of increasing clean energy and efficiency technologies: (1) expanding the portfolio of cleaner energy technology options; (2) leveraging the advantages of energy efficiency; (3) facilitating the development of increasing clean technologies, including renewables, nuclear, and cleaner fossil; (4) improving the existing technologies, systems, and infrastructure; and (5) leveling the playing field for cleaner energy technologies. The Power of Change: Innovation for Development and Deployment of Increasingly Clean Energy Technologies is a call for leadership to transform the United States energy sector in order to both mitigate the risks of greenhouse gas and other pollutants and to spur future economic growth. This study's focus on science, technology, and economic policy makes it a valuable resource to guide support that produces innovation to meet energy challenges now and for the future.

This second edition represents an extensive revision of the ?rst edition, - though the motivation for the book and the intended audiences, as described inthepreviouspreface,remainthesame. Theoveralllengthhasbeenincreased substantially, with revised or expanded discussions of a number of topics, - cluding Yucca Mountain repository plans, new reactor designs, health e?ects of radiation, costs of electricity, and dangers from terrorism and weapons p- liferation. The overall status of nuclear power has changed rather little over the past eight years. Nuclear reactor construction remains at a very low ebb in much of the world, with the exception of Asia, while nuclear power’s share of the electricity supply continues to be about 75% in France and 20% in the United States. However,therearesignsofaheightenedinterestinconsideringpossible nuclear growth. In the late 1990s, the U. S. Department of Energy began new programs to stimulate research and planning for future reactors, and many candidate designs are now contending—at least on paper—to be the next generation leaders. Outside the United States, the commercial development ofthePebbleBedModularReactorisbeingpursuedinSouthAfrica,aFrench- German consortium has won an order from Finlandfor the long-plannedEPR (European Pressurized Water Reactor), and new reactors have been built or planned in Asia. In an unanticipated positive development for nuclear energy, the capacity factor of U. S. reactors has increased dramatically in recent years, and most operating reactors now appear headed for 20-year license renewals.
