What nuclear fission reaction to generate heat instead of

What is nuclear energy?
Is it dangerous or is it the safest power source around? This argument has been
there since 1940’s after the struggle and the terror of war and the usage of an
atomic bomb. Initially, nuclear energy is created to be a peaceful useful form
of new technology. When it was first discovered, everyone’s imagination was
going wild thinking that there would be the unlimited source of electricity,
nuclear-powered houses and cars. Unfortunately, we found out that depending on
nuclear energy is very expensive, full of the possibility of dangers, and is
very complex to produce and to operate. In spite of all the negativities, there
are also many benefits of using nuclear energy. Plus, there are already many
types of nuclear reactors in the world thanks to the brilliance of scientists
around the globe. This proves that usage of nuclear energy is quite common
around the world. Today, nuclear energy meets around 10 percent of the world’s
energy demand and most of it will be built with more improvised technology
compared to the technology of twenty years ago (Dave Levitan, 2016). The
question is, should we continue building the nuclear reactors with better
technology or should we move away from them towards newer or older technology
with different environmental impacts and costs? What are the worst
possibilities of using nuclear energy and what are the reasons why we should
continue using nuclear energy?

 

            First
of all, how does nuclear energy work? Nuclear energy uses a nuclear fission
reaction to generate heat instead of using coal and gas like other power
plants. “The fission nuclear power continues to be an essential part of the
low-carbon electricity generation in the world for decades to come” (Horvath
& Rachlew, 2016). This means that this process of generating energy has a
lot of possibilities to come for another ten or five years. The process
releases a great amount of energy and more neutrons to split other uranium
atoms, thus leading to chain reactions. Nuclear power is generated using
uranium, a metal that is mined as an ore in large quantities, with Canada,
Australia and Kazakhstan providing more than half of the world’s supplies.
Nuclear power plants do not burn fuel. Thus, no greenhouse gas emissions are
produced. Uranium and platinum are one of the materials used in the process of
nuclear fission. These materials have been used for more than 60 percent as an
abundant source of concentrated energy. This means that it has been over 60
years that the world possesses the benefits of cleanly-generated electricity
from nuclear power. Both of these materials need to be handled cautiously as
they are labelled hazardous because of the gamma radiation. In fact, these
materials themselves are barely radioactive. Despite that, it is still
dangerous to people especially the mining workers due to uranium’s decay
products. Radiation is very dangerous to human and its exposure will harm our
body.

            Should
we stop using nuclear energy? What are the disadvantages of using nuclear
energy? Some people already have the first impressions of nuclear as the deadliest
weapon in the world. This is proven by the US who dropped the atomic bomb on
Hiroshima, killing about 140 000 people which almost reach 50 percent
population of the city. The horrible disaster was followed by the second atomic
bomb which dropped on Nagasaki, killing a lot of innocent lives. “An atomic
bomb explosion creates radioactive dust that falls out of the sky into the area
around the site of the explosion and is also carried out way beyond and
contaminates the ground, water and the food chain in environments farther away”
(Lemon, 2017). This dreadful news is one of the most important reasons why the
world is afraid of handling nuclear energy. The nuclear energy which can be very
useful was used as a weapon which is lethal. This type of weapon is difficult
to build because it needs more advanced technology as well as the specific
amounts of isotopes which is uranium or plutonium. Luckily, only a few
countries hold this deadly weapon. According to history, after World War 2, the
main reason for holding a nuclear is because of the rivalry during the war.
This is because the country which held that weapon is labelled as one of the
strongest countries. Basically, the World War 2 had ended as nuclear bomb named
Fat Man was dropped on Nagasaki which causes massive explosions. So, the
development of nuclear as a weapon will never stop as technology is getting
more advanced. Instead of relying on nuclear energy, maybe now we should get
rid of nuclear for good.

 

            Next,
nuclear energy is still considered as dangerous. “A lot of people believe that
nuclear energy only comes with minimal disadvantages, easily outnumbered by the
great numbers of advantages” (Eubanks,2016). But, considering the
disadvantages, another reason to stop using nuclear energy is that of nuclear
waste. Nuclear energy undergoes nuclear fission, splitting of uranium which
results in the generation of heat. The resulting uranium then needs to be
removed safely, because they are radioactive. In this case, the waste will just
keep coming and even though power plants take actions by storing the waste.
Besides that, water pollution is also a problem when handling nuclear energy.
The heat produced when nuclear fission takes place need to be cooled down by
water which then turned into steam to turn the turbine to generate energy. The
water then flows into nearby wetlands. Even though no radiation leaks to the
water, other substances such as metals and pollutants get into the water thus
leading to damage to ecosystems nearby the power plants. Furthermore, another
reason to avoid using nuclear energy is that of recent nuclear radiation
accidents. If the radioactive waste that comes from the power plant is
dangerous, imagine when the whole power plant breaks down or explode. The Chernobyl
disaster which causes over more than 2.5 million of Ukrainians are dealing with
health trouble and approximately 30,000 people died after the accident. “Various international organizations
have reported on the thousands of people in the Chernobyl area who have died
from radiation-induced cancers” (The Learning Network, 2012). Another nuclear
accident also occurred in Fukushima, Japan which caused impact to environmental
disaster. Even though less casualty recorded after the incident, people who were
near the power plant still affected by the radiation which is bad to human. So,
in my opinion, these few reasons is already enough to put a stop to the usage
of nuclear energy.

 

Despite all the reason to
stop using nuclear energy, there is some reason that we should continue relying
on this energy. The nuclear power plant is compact, which will be it
quintessentially blankets a territory the measure of a football stadium Also
its surroundings. Contrasted with those sun oriented cells, wind turbines
Furthermore developing biomass, they at requirement an immense territory for
land to expand the energy handled. In this era, it gives so many advantages
because when the power station doesn’t have to take the huge size of land,
there will be the opportunity to the other for developing any kind of
development that required by the people now. Is the nuclear power safe to
environment and human? There would a few disasters that stun this globe due to nuclear
vitality. Clinched alongside 26th April 1986, those world’s Most exceedingly
bad nuclear catastrophe to date which happened for Chernobyl, Ukraine. This
catastrophe happened when a sudden passing surge in energy Throughout a reactor
frameworks test brought about a blast and fire that wrecked unit 4. Gigantic
sums of radiation release What’s more spread through the air crosswise over the
western Soviet Union and Europe.  Give or
take 220,000 kin required should be moved starting with their home due to the
catastrophe.  There were also several
disasters happen such as Three Mile Island in Middletown, Pennsylvania, the USA
in 28th March 1978 and Fukushima Daiichi nuclear power plant in
Japan, March 2011. Because of the past disasters of nuclear happened, the
developers of the present nuclear power plants have beat those shortcomings
about previous nuclear power plant the current power plant’s cooling process
does not rely on external electricity source or external water supplies. They
use the “passive safety system” which
is they use water nourished eventually Tom’s perusing gravity, gas-pressurized
water tanks, what’s more, regular convection heat exchangers. Those reactors
likewise might be introduced underground that advertising included security
against unapproved entry what’s more outer dangers.  For the safety of nuclear power plants, they
also introduce the “passive nuclear
safety”. By the definition of Wikipedia, passive nuclear safety is a “safety feature of a nuclear reactor
that does not require operator actions or electronic feedback in order to shut
down safely in the event of a particular type of emergency (usually overheating
resulting from a loss of coolant or loss of coolant flow). If the reactor tending
to rely on the engineering component which is the predicted behaviour according
to their known in laws of physics would be slow rather than accelerate”. By
having this safety system, it can improve the safety of the nuclear power plant
in the present and future. For the example of the system is AP1000 reactor
design that being sold by Westinghouse in the United States. This reactor merges
passive safety measures for core water injection, residual and reliable heat
removal, and containment vessel cooling. 
These system does not require any AC power and employs no fans, pumps or
other rotating machinery. The valves in these systems require power to stay
closed. The safety valves open automatically using mechanical force when the
power interrupted or otherwise fail. In reducing the risk of operator or
maintenance accidents, these adjustments have the added benefit of
significantly reducing the overall complexity of the plant and thereby.

 

Who would have thought
that nuclear energy was protecting the environment? “Nuclear power is one of
the least damaging sources of energy for the environment, and the green
movement must accept its expansion if the world is to avoid dangerous climate
change, some of the world’s leading conservation biologists have warned”. (Steve
Connor,2016). By far, nuclear energy will be America’s biggest sourball clean,
emission-free electricity, handling no greenhouse gasses or air pollutants. The
industry’s duty to the surroundings extends to ensuring untamed life also their
propensities.  In the effort to improve
the nation’s air quality, nuclear power plants play the major role in overall
compliance with the Clean Air Act of 1970. Greenhouse gasses alternately
emanations connected with corrosive downpour alternately urban exhaust cloud
would not be prepared because of they produce heat from those outflows instead
of smoulder fuel. Extra adaptability done consenting with clean air necessities
can get by using more nuclear energy. In America, about 65% of all power that
doesn’t radiate greenhouse gasses in the transform of generating force to homes
what’s more organizations are prepared toward atomic plants. Nuclear power
plants, which don’t radiate carbon dioxide, represent those dominant part of
voluntary diminishments previously, greenhouse gas emanations in the electric
force segment. It also not generating nitrogen oxides (NOx) that a forerunner
about ground-level ozone also smog, sulphur hexafluoride which produces
corrosive rain, the particulate matter for example, such that smoke and dust,
and free of mercury.  The ecology also
was preserved when using the nuclear power plants. Nuclear energy is those a
standout amongst those least effects on surroundings on it doesn’t emanate air
contamination. Even the nuclear plant starts producing electricity, a
radiological environment monitoring program begins. The purpose of the program
is to screen air, the surface also groundwater, drain structure dairies, furthermore
vegetation. The operator of the plant also sends the tests to state also
central controllers to free confirmation. So as will ensure water nature also
oceanic life, those cooling water released starting with a plant must help
elected clean water one gesture prerequisites and state guidelines.  Nuclear plant operation is reviewed by the NRC
to guarantee no unfriendly affects to water nature also oceanic nature. Additionally,
there are special nature park or wildlife sanctuaries were developed by the
plant in order to screen and ensure jeopardized also debilitated species. These
ventures need to be perceived eventually Tom’s perusing those untamed lives
Habitat Council, Audubon Society, national untamed life league and what’s to
come for you. What’s more, the lion’s share of Corps parts doesn’t stay in
their starting work areas once their common fish also untamed life
administration. Multitudinous investigations substantiate that nuclear energy’s
life-cycle discharges would tantamount to renewable manifestations of power era,
for example, hydropower what’s more solar, incalculable over the individuals
for regular gas-fired alternately coal-fired force plants. Nuclear power
likewise goes about a fundamental part of giving clean vitality to worldwide
reasonable advancement.  The world has
realized the expansion of nuclear technology and triumphant international
development for energy, medicine, food preservation, agriculture, industry,
hydrology and ecology in support of sustainable development.

 

            In
a nutshell, now we know how the nuclear work, so all the facts that why we
should get rid of and the main reason to rely on the nuclear energy. It is proven
that this type of energy is risky, dangerous and deadly. Fortunately, despite
all the negativities, it is also a neat and useful type of energy. In Malaysia,
there are only a few nuclear facilities around which is used only for research.
In this era of an organization, Malaysia is one of the countries that is moving
towards development”. Malaysia has no choice but to go for nuclear energy in
less than 15 years from now to ensure the country is able to cater for its
energy needs in the future”. (Zazali Musa,2016). So, maybe we should start
thinking about the possibilities that we could have when this type of
technology is around. Even though we know the risks that if one country tries
to hold on this energy, which may lead to world war, but try to think of the
good sides of it which may bring us towards new and more advanced technology
that we could hold on to. To sum up, nuclear energy is far from dead, in
my point of view. Each form of energy provider has its own advantages and
disadvantages, the most important thing is we must consider the consequences.
