Disadvantages
of Nuclear Energy
1. Radioactive Waste : The waste
produced by nuclear reactors needs to be disposed off at a safe place
since they are extremely hazardous and can leak radiations if not stored
properly. Such kind of waste emits radiations from tens to hundreds of years.
The storage of radioactive waste has been major bottleneck for the expansion of
nuclear programs. The nuclear wastes contain radio isotopes with long
half-lives. This means that the radio isotopes stay in the atmosphere in some
form or the other. These reactive radicals make the sand or the water
contaminated. It is known as mixed waste. The mixed wastes cause hazardous
chemical reactions and leads to dangerous complications. The radioactive wastes
are usually buried under sand and are known as vitrification. But these wastes
can be used to make nuclear weapons.
2. Nuclear Accidents : While so many
new technologies have been put in place to make sure that such disasters won’t
happen again like the ones Chernobyl or more recently Fukushima but the risk
associated with them are relatively high. Even small radiation leaks can cause
devastating effects. Some of the symptoms include nausea, vomiting, diarrhea
and fatigue. People who work at nuclear power plants and live near those areas
are at high risk of facing nuclear radiations, if it happens.
3. Nuclear Radiation : There are
power reactors called breeders. They produce plutonium. It is an element which
is not found in the nature however it is a fissionable element. It is a
by-product of the chain reaction and is very harmful if introduced in the
nature. It is primarily used to produce nuclear weapons. Most likely, it is
named as dirty bomb.
4. High Cost :
Another practical disadvantage of using nuclear energy is that it needs a lot
of investment to set up a nuclear power station. It is not always possible by
the developing countries to afford such a costly source of alternative energy.
Nuclear power plants normally take 5-10 years to construct as there are several
legal formalities to be completed and mostly it is opposed by the people who
live nearby.
5. National Risk :
Nuclear energy has given us the power to produce more weapons than to produce
things that can make the world a better place to live in. We have to become
more careful and responsible while using nuclear energy to avoid any sort of
major accidents. They are hot targets for militants and terrorist
organizations. Security is a major concern here. A little lax in security can
prove to be lethal and brutal for humans and even for this planet.
6. Impact on Aquatic Life :
Eutrophication is another result of radioactive wastes. There are many seminars
and conferences being held every year to look for a specific solution. But
there is no outcome as of now. Reports say that radioactive wastes take almost
10,000 years to get back to the original form.
7. Major Impact on Human
Life : We all remember the disaster caused during the Second World
War after the nuclear bombs were dropped over Hiroshima and Nagasaki. Even
after five decades of the mishap, children are born with defects. This is
primarily because of the nuclear effect. Do we have any remedy for this? The
answer is still no.
8. Fuel Availability :
Unlike fossil fuels which are available to most of the
countries, uranium is very scarce resource and exist in only few of the
countries. Permissions of several international authorities are required before
someone can even thought of building a nuclear power plant.
9. Non Renewable :
Nuclear energy uses uranium which is a scarce resource and is not found in many
countries. Most of the countries rely on other countries for the constant
supply of this fuel. It is mined and transported like any other metal. Supply
will be available as long as it is there. Once all extracted, nuclear plants
will not be of any use. Due to its hazardous effects and limited supply, it
cannot be termed as renewable.
Various nuclear energy programs are
undergoing in developed as well as developing nations like India. Not to
mention, nuclear energy advantages are far ahead of advantages
of fossil fuels. That is the reason that it has become most favored technology
to produce energy.
