Increasing awareness of the need to reduce greenhouse gas emissions has renewed interest in nuclear power generation. At the same time, the longstanding logjam over how to manage spent nuclear fuel continues to hamper the expansion of nuclear power. If nuclear power is to be a sustainable option for the
The world faces serious difficulties in obtaining the energy that will be needed in coming decades for a growing population, especially given the problem of climate change caused by fossil fuel use. This book presents a view of nuclear energy as an important carbon-free energy option. It discusses the nuclear fuel cycle, the types of reactors used today and proposed for the future, nuclear waste disposal, reactor accidents and reactor safety, nuclear weapon proliferation, and the cost of electric power.
A sustainable energy future may, according to some, include nuclear power as a gap filler in the transition from nonsustainable fossil fuel to renewable energy, even though the needed uranium is not itself renewable. The most prominent argument of advocates for nuclear power is that it does not release greenhouse gases. Chapter 13 provides knowledge of nuclear power, nuclear waste, renewable energy and conserve energy.
When will the oil run out? Various estimates put this anywhere from 20 years from
now to more than a century in the future. The shortfall in energy might eventually
be made up by developments in nuclear fusion, fuel cells, and solar technologies,
but what can substitute for gasoline and diesel in all the internal combustion enginepowered
vehicles that will continue to be built worldwide until then? And what will
stand in for petrochemicals as sources of building blocks for the extensive range of
“synthetics” that became indispensable during the twentieth century?...
The serious challenge facing the world today, in obtaining enough energy for growing population and in controlling the carbon emission caused by fossil fuel use, calls for nuclear energy as an alternative power source. This book presents research work and technical experience from several power plants and research institutions around the world from practical prospective.
Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs.
In the most common frequency
AE used for testing, 100-300kHz, the AE sensor can detect a signal for surface
movement of 10-13
m or less than one thousand times smaller than the size of an atom.
As a monitoring device for structural integrity, acoustic sensors are more effective
distance from a few tens of feet. It can be compared with the accelerations
commonly used to assess the condition of the bridge, for example, through the techniques of method
At the same time, both countries chemically process liquid HLW in order to immobilize it for safer storage and disposal. The United States and Russia, however, have different approaches to and long-term strategies for realizing end points for SNF and HLW. The United States currently plans to transport SNF to a geologic repository for disposal without chemical processing. Russia plans to develop the capacity to chemically p
Another closely-related dynamic is a fundamental shift that is taking place in terms of priority
geographic markets. A 2011 global CEO survey by PricewaterhouseCoopers (PWC’s Growth
Reimagined) found that the large majority of corporate executives have shifted their primary focus
to developing markets. Although doing business in these markets is nothing new, making them the
primary target market, where firms plan to invest the majority of their efforts and expect the majority
of their future sales, is new and significant.
he Senate Committee on Environment and Public Works, the House
Committee on Foreign Affairs, the House Committee on Energy
and Commerce, the Senate Committee on Foreign Relations, and
the House Subcommittee on International Development, Finance,
and Monetary Policy requested an assessment of energy and environmental
technology transfer to Central Europe and the former Soviet
Union. The intent was to determine how U.S. energy technology can help
resolve the economic and environmental problems in the region....
Both the retreat of the glaciers and the rise of oxygen in the ocean may have
spurred the rise of the animals. All animals need oxygen to fuel their metabolism
and to build their tissues. The low levels of oxygen in the oceans may have made
it impossible for the ancestors of animals to evolve into multicellular creatures.
If a rise in oxygen opened the door for animal evolution, what pushed the ani-
mals through? Part of that answer may lie within the animals themselves—in
particular, in the set of genes that control their development.
The recent discovery of the direct oxidation of spermine via spermine oxi-dase (SMO) as a mechanism through which specific antitumor polyamine
analogues exert their cytotoxic effects has fueled interest in the study of the
polyamine catabolic pathway.
In the portable sector shipments were relatively ﬂ at between 2010 and 2011, increasing by only
1.5%. Three portable fuel cell electronics chargers were launched this year and therefore we expect
even modest sales into this lucrative market to grow portable shipments seven-fold in 2012. With
the small size of portable units, mostly in the sub-kilowatt range, they do not signiﬁ cantly affect
the total megawatt ﬁ gure, which for portable applications remained broadly ﬂ at between 2010 and
2011, but is expected to grow 50% in 2012 from a low base.
Presently, India occupies a leading place among Asian nations in the indigenous design, development, construction, and operation of nuclear power reactors. Nuclear power generation in India is based on a three-stage plan to eventually make use of the abundant national resources of thorium, through the use of fast breeder reactors. To achieve this long-range goal, India had to necessarily start with setting up heavy water–moderated, natural uranium–fueled power reactors to produce the plutonium required for the subsequent stages....

The process of generating power depends on several energy-conversion processes, starting with the chemical energy in fossil fuels or the nuclear energy within the atom. This energy is converted to thermal energy, which is then transferred to the working fluid, in our case, steam. This thermal energy is converted to mechanical energy with the
As the fastest growing source of energy in the world, wind has a very important role
to play in the global energy mix. This becomes increasingly apparent as many
countries begin to phase out traditional fossil fuels, while some re-evaluate their
comfort level with nuclear power generation. The conversion of wind’s kinetic energy
into another desired form dates back millennia. The years since have afforded some
time for maturation of the technology.
