an object by the mechanical work of moving it a distance of 1 metre
against a force of 1 newton. Newton is a unit of force equal to the force

describes the minimum energy which must be available to a

Conservation of Energy
is the process of changing energy from one of
its forms into another. In physics, energy is a quantity that provides the
capacity to perform many actions—some as simple as lifting or warming an
object. In addition to being convertible, energy is transferable to a
different location or object, but it
cannot be created
. Energy in many of its forms may be used in natural
processes, or to provide some service to society such as heating,
refrigeration, lighting, or performing mechanical work to operate
machines. For example, in order to heat your home, your furnace can burn
fuel, whose chemical potential energy is thus converted into
, which is then transferred to
your home's air in order to raise its temperature. In another example, an
internal combustion engine burns gasoline to cause pressure that pushes
the pistons, thus performing work in order to accelerate your vehicle,
ultimately converting the fuel's
your vehicle's additional kinetic energy
corresponding to its increase in speed.
, this is an indirectly
observed quantity often understood as the ability of a physical system to
do work on other physical systems. Since work is defined as a force acting
through a distance (a length of space), energy is always equivalent to the
ability to exert force (a pull or a push) against an object that is moving
along a definite path of certain length.

is the name of a nuclear power plant design by GE
Hitachi Nuclear Energy (GEH). The S-PRISM represents GEH's Generation IV
reactor solution to closing the nuclear fuel cycle and is also part of its
Advanced Recycling Center (ARC) proposition to U.S. Congress to deal with
nuclear waste. S-PRISM is a commercial implementation of the Integral Fast
Reactor developed by Argonne National Laboratory between 1984 and 1994. It
is a sodium-cooled fast breeder reactor, based on the Experimental Breeder
Reactor II (EBR-II) design, scaled up by a factor of ten. The design
utilizes reactor modules, each having a power output of 311 MWe, to enable
factory fabrication at low cost. In an identical fashion to the EBR-II
that it is based on, the reactor would transition to a much lower power
level whenever temperatures rise significantly, moreover the reactor
vessel modules are pool type, as opposed to loop type, with the pool
conferring substantial thermal inertia and the final key safety feature
includes a "RVACS", which is a passive reactor vessel air cooling system
to remove decay heat. These safety systems are passive and therefore
always operate and are to prevent core damage when no other means of heat
removal are available.

confused with molten salt-cooled high temperature reactors (fluoride
high-temperature reactors, FHRs) that use a solid fuel. Molten salt
reactors, as a class, include both burners and breeders in fast or thermal
spectra, using fluoride or chloride salt-based fuels and a range of
fissile or fertile consumables. LFTRs are defined by the use of fluoride
fuel salts and the breeding of thorium into uranium-233 in the thermal

Molten Salt Reactor
is a class of generation IV nuclear fission reactor in which the
primary nuclear reactor coolant, or even the fuel itself, is a molten salt
mixture. MSRs can run at higher temperatures than water-cooled reactors
for a higher thermodynamic efficiency, while staying at low vapour
pressure. The nuclear fuel may be solid or dissolved in the coolant. In
many designs the nuclear fuel dissolved in the coolant is uranium
tetrafluoride (UF4). The fluid becomes critical in a graphite core that
serves as the moderator. Some solid-fuel designs propose ceramic fuel
dispersed in a graphite matrix, with the molten salt providing low
pressure, high temperature cooling. The salts are much more efficient than
compressed helium (another potential coolant in Generation IV reactor
designs) at removing heat from the core, reducing the need for pumping and
piping and reducing the core size. The concept was established in the
1950s. The early Aircraft Reactor Experiment (1954) was primarily
motivated by the small size that the design could provide, while the
Molten-Salt Reactor Experiment (1965–1969) was a prototype for a thorium
fuel cycle breeder reactor nuclear power plant. The increased research
into Generation IV reactor designs included a renewed interest in the
Thorium Fuel Cycle
is a nuclear fuel cycle that uses an
isotope of thorium, 232Th, as the fertile material. In the reactor, 232Th
is transmuted into the fissile artificial uranium isotope 233U which is
the nuclear fuel. Unlike natural uranium, natural thorium contains only
trace amounts of fissile material (such as 231Th), which are insufficient
to initiate a nuclear chain reaction. Additional fissile material or
another neutron source is necessary to initiate the fuel cycle. In a
thorium-fuelled reactor, 232Th absorbs neutrons to produce 233U. This
parallels the process in uranium breeder reactors whereby fertile 238U
absorbs neutrons to form fissile 239Pu. Depending on the design of the
reactor and fuel cycle, the generated 233U either fissions in situ or is
chemically separated from the used nuclear fuel and formed into new
nuclear fuel. The thorium fuel cycle has several potential advantages over
a uranium fuel cycle, including thorium's greater abundance, superior
physical and nuclear properties, reduced plutonium and actinide
production, and better resistance to nuclear weapons proliferation when
used in a traditional light water reactor though not in a molten salt
is a nuclear reactor that generates more
fissile material than it consumes. These devices achieve this because
their neutron economy is high enough to breed more fissile fuel than they
use from fertile material, such as uranium-238 or thorium-232. Breeders

light water reactors, but interest declined after the 1960s as more
uranium reserves were found, and new methods of uranium enrichment reduced

are a type of nuclear fission reactor
which are smaller than conventional reactors, and manufactured at a plant

less on-site construction, increased containment efficiency, and
heightened nuclear materials security. SMRs have been considered to be
less expensive than traditional nuclear reactors, although critics have
questioned the cost benefits when compared to solar energy, wind energy,
and natural gas. Small reactors are defined by the International Atomic
Energy Agency as those with an electricity output of less than 300 MW,
although general opinion is that anything with an output of less than 500
MWe counts as a small reactor.
Loop Reactor Design
Linear no-threshold Model
is a model used in radiation
protection to quantify radiation exposure and set regulatory limits. It
assumes that the long term, biological damage caused by ionizing radiation
(essentially the cancer risk) is directly proportional to the dose. This
allows the summation by dosimeters of all radiation exposure, without
taking into consideration dose levels or dose rates. In other words,
radiation is always considered harmful with no safety threshold, and the
sum of several very small exposures are considered to have the same effect
as one larger exposure (response linearity).
is the hypothesis that low doses of
(within the region
of and just above natural background levels) are beneficial, stimulating
the activation of repair mechanisms that protect against disease, that are
not activated in absence of ionizing radiation. The reserve repair
mechanisms are hypothesized to be sufficiently effective when stimulated
as to not only cancel the detrimental effects of ionizing radiation but
also inhibit disease not related to radiation exposure (see hormesis).
This counter-intuitive hypothesis has captured the attention of scientists

that a second subsequent heat
engine may extract energy from the waste heat (energy) of the working
fluid of the first engine. By combining these multiple streams of work
upon a single mechanical shaft turning an electric generator, the overall

overall efficiency of say 34% (in a single cycle) to possibly an overall
efficiency of 51% (in a mechanical combination of two cycles) in net
Carnot thermodynamic efficiency. This can be done because heat engines are
only able to use a portion of the energy their fuel generates (usually

is a passive heat exchanger that transfers the

electronic or a mechanical device to a fluid medium, often air or a liquid
coolant, where it is dissipated away from the device, thereby allowing
regulation of the device's temperature at optimal levels. In computers,
heat sinks are used to cool central processing units or graphics
processors. Heat sinks are used with high-power semiconductor devices such
as power transistors and optoelectronics such as lasers and light emitting
diodes (LEDs), where the heat dissipation ability of the component itself
is insufficient to moderate its
is the property of a material to conduct heat.
Heat transfer occurs at a lower rate across materials of low thermal
conductivity than across materials of high thermal conductivity.
Correspondingly, materials of high thermal conductivity are widely used in
heat sink applications and materials of low
conductivity are used as thermal insulation. The thermal
conductivity of a material may depend on temperature. The reciprocal of
thermal conductivity is called thermal resistivity. Thermal conductivity
is actually a tensor, which means it is possible to have different values
in different directions.

, photolysis, or photodecomposition is a chemical
reaction in which a chemical compound is broken down by photons. It is
defined as the interaction of one or more photons with one target
molecule. Photodissociation is not limited to visible light. Any photon
with sufficient energy can affect the chemical bonds of a chemical
compound. Since a photon's energy is inversely proportional to its
wavelength, electromagnetic waves with the energy of visible light or
higher, such as ultraviolet light, x-rays and gamma rays are usually
involved in such reactions.
is a system that converts heat or thermal energy
, which can then be used to do
mechanical work. it does this by bringing a working substance from a
higher state temperature to a lower state temperature. A heat "source"
generates thermal energy that brings the working substance to the high
temperature state. The working substance generates work in the
"working body" of the engine while transferring heat to the colder "sink"
until it reaches a low temperature state. During this process some of the
thermal energy is converted into work by exploiting the properties of the
working substance. The working substance can be any system with a non-zero
heat capacity, but it usually is a gas or liquid. During this process, a
lot of heat is lost to the surroundings, i.e. it cannot be used. In
general an engine converts energy to mechanical work. Heat engines
distinguish themselves from other types of engines by the fact that their
efficiency is fundamentally limited by
. Although this efficiency limitation can be a
drawback, an advantage of heat engines is that most forms of energy can be
easily converted to heat by processes like exothermic reactions (such as
combustion), absorption of light or energetic particles, friction,
dissipation and resistance. Since the heat source that supplies thermal
energy to the engine can thus be powered by virtually any kind of energy,
heat engines are very versatile and have a wide range of applicability.

through the engine wall or a heat exchanger. Steam Engine
Internal Combustion Engine
is a heat engine where the combustion of a
fuel occurs with an oxidizer (usually air) in a combustion chamber that is
an integral part of the working fluid flow circuit. In an internal
combustion engine the expansion of the high-temperature and high-pressure
gases produced by combustion apply direct force to some component of the
engine. The force is applied typically to pistons, turbine blades, rotor
or a nozzle. This force moves the component over a distance, transforming

is a system that converts heat or thermal energy
—to mechanical energy
, which can then be used to do mechanical
. It does this by
bringing a working substance from a higher state temperature to a lower
state temperature. A heat "source" generates thermal energy that brings
the working substance to the high temperature state. The working substance
generates work in the "working body" of the engine while transferring heat
to the colder "sink" until it reaches a low temperature state. During this
process some of the thermal energy is converted into work by exploiting
the properties of the working substance. The working substance can be any
system with a non-zero heat capacity, but it usually is a gas or liquid.
During this process, a lot of heat is lost to the surroundings, i.e. it
cannot be used.

pressures lower than the ambient atmospheric pressure. Other methods of
pressure measurement involve sensors which can transmit the pressure

Ocean Wave Current Energy
is the transport of energy by wind waves, and the capture of that energy
to do useful work – for example, electricity generation, water
desalination, or the pumping of water (into reservoirs). A machine able to
exploit wave power is generally known as a wave energy converter (WEC).
Wave power is distinct from the diurnal flux of tidal power and the steady
gyre of ocean currents. Wave-power generation is not currently a widely
employed commercial technology, although there have been attempts to use
it since at least 1890. In 2008, the first experimental wave farm was
opened in Portugal, at the Aguçadoura Wave Park.
Tidal Stream Generator
is a machine that extracts energy
from moving masses of water, in particular tides, although the term is
often used in reference to machines designed to extract energy from run of
river or tidal estuarine sites. Certain types of these machines function
very much like underwater wind turbines, and are thus often referred to as
tidal turbines. They were first conceived in the 1970s during the oil
crisis. Tidal stream generators are the cheapest and the least
ecologically damaging among the three main forms of tidal power
Oscillating Water Column
are a type of Wave Energy Converter
(WEC) that harness energy from the oscillation of the seawater
inside a chamber or hollow caused by the action of waves. OWCs have shown
promise as a renewable energy source with low environmental impact.
Because of this, multiple companies have been working to design
increasingly efficient OWC models.

New technology could generate 40% of the world’s electricity where
seawater and freshwater meet
. Researchers at Penn State University
have developed a new technology that they believe will be capable of
producing large amounts of energy – possibly more than one-third the
amount needed to meet global energy demands – in coastal areas where
seawater and freshwater meet. “The goal of this technology,” assistant
environmental engineering professor Christopher Gorski explained earlier
this month in a statement, “is to generate electricity from where the
rivers meet the ocean. It's based on the difference in the salt
concentrations between the two water sources.” According to Gorski and his
colleagues, that difference in salinity levels could potentially create
enough energy to meet nearly 40 percent of the world’s electricity needs.
However, methods that experts currently use to harness that power have
failed to fully capitalize on that potential.

are fuels formed by natural processes such as
anaerobic decomposition of buried dead organisms, containing energy
originating in ancient photosynthesis. The age of the organisms and their
resulting fossil fuels is typically millions of years, and sometimes
exceeds 650 million years. Fossil fuels contain high percentages of carbon
and include petroleum, coal, and natural gas. Other commonly used
derivatives include kerosene and propane. Fossil fuels range from volatile
materials with low carbon: hydrogen ratios like methane, to liquids like
petroleum, to nonvolatile materials composed of almost pure carbon, like
anthracite coal. Methane can be found in hydrocarbon fields either alone,
associated with oil, or in the form of methane clathrates.

are plastics derived from renewable
biomass sources, such as vegetable fats and oils, corn starch, or
microbiota. Bioplastic can be made from agricultural by-products and also
from used plastic bottles and other containers using microorganisms.
Common plastics, such as fossil-fuel plastics (also called petrobased
polymers), are derived from petroleum or natural gas. Production of such
plastics tends to require more fossil fuels and to produce more greenhouse
gases than the production of biobased polymers (bioplastics). Some, but
not all, bioplastics are designed to biodegrade. Biodegradable bioplastics
can break down in either anaerobic or aerobic environments, depending on
how they are manufactured. Bioplastics can be composed of starches,
cellulose, biopolymers, and a variety of other materials.

Carbon-Fiber Reinforced Polymer
is an extremely
strong and light fiber-reinforced plastic which contains carbon fibers.
CFRPs can be expensive to produce but are commonly used wherever high
strength-to-weight ratio and rigidity are required, such as aerospace,
automotive, civil engineering, sports goods and an increasing number of
other consumer and technical applications. The binding polymer is often
a thermoset resin such as epoxy, but other thermoset or thermoplastic
polymers, such as polyester, vinyl ester or nylon, are sometimes used. The
composite may contain other fibers, such as an aramid (e.g. Kevlar, Twaron),
aluminium, ultra-high-molecular-weight polyethylene (UHMWPE) or glass
fibers, as well as carbon fiber. The properties of the final CFRP product
can also be affected by the type of additives introduced to the binding
matrix (the resin). The most frequent additive is silica, but other
additives such as rubber and carbon nanotubes can be used. The material is
also referred to as graphite-reinforced polymer or graphite
fiber-reinforced polymer (GFRP is less common, as it clashes with
glass-(fiber)-reinforced polymer). In product advertisements, it is
sometimes referred to simply as graphite fiber for short

made of a polymer matrix reinforced with fibres. The fibres are usually
glass, carbon, aramid, or basalt. Rarely, other fibres such as paper or

are composite materials synthesized
by filling a metal, polymer, or ceramic matrix with hollow particles
called microballoons. In this context, "syntactic" means "put together".
The presence of hollow particles results in lower density, higher specific
strength (strength divided by density), lower coefficient of thermal
expansion, and, in some cases, radar or sonar transparency.
are microscopic spheres of glass
manufactured for a wide variety of uses in research, medicine, consumer
goods and various industries. Glass microspheres are usually between 1 and
1000 micrometers in diameter, although the sizes can range from 100
nanometers to 5 millimeters in diameter. Hollow glass microspheres,
sometimes termed microballoons or glass bubbles, have diameters ranging
from 10 to 300 micrometers.
is the property of materials that exhibit both viscous and elastic
characteristics when undergoing deformation. Viscous materials, like
honey, resist shear flow and strain linearly with time when a stress is
applied. Elastic materials strain when stretched and quickly return to
their original state once the stress is removed. Viscoelastic materials
have elements of both of these properties and, as such, exhibit
time-dependent strain. Whereas elasticity is usually the result of bond
stretching along crystallographic planes in an ordered solid, viscosity is
the result of the diffusion of atoms or molecules inside an amorphous
polypropylene (PP-R) pipe for use in pressurized plumbing
and mechanical systems of all sizes. Our products are reliable,
competitively priced, and environmentally friendly.
is a thermoplastic polymer used in a wide variety of
applications including packaging and labeling, textiles (e.g., ropes,
thermal underwear and carpets), stationery, plastic parts and reusable
containers of various types, laboratory equipment, loudspeakers,
automotive components, and polymer banknotes. An addition polymer made
from the monomer propylene, it is rugged and unusually resistant to
many chemical solvents, bases and acids. Polypropylene has a relatively
slippery "low energy surface" that means that many common glues will not
form adequate joints. Joining of polypropylene is often done using welding
processes. In 2013, the global market for polypropylene was about 55
million tonnes. Polypropylene is the world's second-most widely produced
synthetic plastic, after polyethylene.Fuel Cells

sometimes denoted 1H, 2H, and 3H. The first two of these are stable while
3H has a half-life of 12.32 years. All heavier isotopes are synthetic and

the most stable, and 7H is the least.Hydrogen
Magnetic Confinement Fusion
is an approach to generating
fusion power that uses magnetic fields
(which is a magnetic influence of electric currents and magnetic
materials) to confine the hot fusion fuel in the form of a plasma.
Magnetic confinement is one of two major branches of fusion energy
research, the other being inertial confinement fusion. The magnetic
approach is more highly developed and is usually considered more promising
for energy production.

A plasma has properties unlike those of the other states.
Developing Nuclear Fusion in a Basement with a Reclusive
Magnetized Target Fusion
combines features of magnetic
confinement fusion (MCF) and inertial confinement fusion (ICF). Like the
magnetic approach, the fusion fuel is confined at lower density by
magnetic fields while it is heated into a plasma. As with the inertial
approach, fusion is initiated by rapidly squeezing the target to greatly
increase fuel density and temperature. Although the resulting density is
far lower than in ICF, it is thought that the combination of longer
confinement times and better heat retention will let MTF operate, yet be
easier to build. The term magneto-inertial fusion (MIF) is similar, but
encompasses a wider variety of arrangements. The two terms are often
applied interchangeably to experiments.

a radioactive isotope of strontium produced by nuclear fission, with a
half-life of 28.8 years. It undergoes β− decay into yttrium-90, with a
decay energy of 0.546 MeV. Strontium-90 has applications in medicine and
industry and is an isotope of concern in fallout from nuclear weapons and
is an important radioisotope of iodine discovered
by Glenn Seaborg and John Livingood in 1938 at the University of
California, Berkeley. It has a radioactive decay half-life of about eight
days. It is associated with nuclear energy, medical diagnostic and
treatment procedures, and natural gas production. It also plays a major
role as a radioactive isotope present in nuclear fission products, and was
a significant contributor to the health hazards from open-air atomic bomb
testing in the 1950s, and from the Chernobyl disaster, as well as being a
large fraction of the contamination hazard in the first weeks in the
Fukushima nuclear crisis. This is because I-131 is a major fission product
of uranium and plutonium, comprising nearly 3% of the total products of
fission (by weight). See fission product yield for a comparison with other
radioactive fission products. I-131 is also a major fission product of
uranium-233, produced from thorium
Effects of Nuclear Explosions
The energy released from a nuclear weapon detonated in the troposphere can
be divided into four basic categories: Blast—40–50% of total energy.
Thermal radiation—30–50% of total energy. Ionizing radiation—5% of total
energy (more in a neutron bomb). Residual radiation—5–10% of total energy
with the mass of the explosion.
Fukushima Daiichi Nuclear Disaster
was an energy accident at
the Fukushima Daiichi Nuclear Power Plant in Fukushima, initiated
primarily by the tsunami following the Tōhoku earthquake on 11 March 2011.
Immediately after the earthquake, the active reactors automatically shut
down their sustained fission reactions. However, the tsunami disabled the
emergency generators that would have provided power to control and operate
the pumps necessary to cool the reactors. The insufficient cooling led to
three nuclear meltdowns, hydrogen-air explosions, and the release of
radioactive material in Units 1, 2, and 3 from 12 March to 15 March. Loss
of cooling also caused the pool for storing spent fuel from Reactor 4 to
overheat on 15 March due to the decay heat from the fuel rods.
