Read the following passage and answer the questions that follow:
1. Nuclear capability gives a status to the country in the community of nations. No nation can
afford to make destructive use of the nuclear energy without risking a World War. That is
why America did not make use of nuclear weapon in the Vietnam War though it had
become a matter of prestige for her. Similarly Russia preferred to pull out her missile bases
from Cuba instead of coming in direct conflict with a nuclear power, America. But India,
since she started adopting nuclear technology, had decided to make only peaceful use of
nuclear energy. The fear expressed by Pakistan and the comments made in the Chinese
press are more for the sake of propaganda than for the projection of truth.
2. India needs nuclear energy in order to meet her power shortage. She has been depending
upon hydroelectric power which is undependable because of the uncertainty of rainfall.
Good quality of coal which is another source of energy cannot be extracted commercially
because it lies very deep and the cost of extraction is very high. India is not producing much
of oil, rather she has to import nearly 74 per cent of her total consumption. So the only
alternative with India is to have a cheaper and more dependable source of energy. The
known reserves of thorium in India are sufficient to last many hundred years. That is why
India has already commissioned two nuclear power stations, one at Tarapur and the other
at RanaPratap Sagan. Each one has the installed capacity of producing 420 M.W. of
electricity. Two other at Kalpakkam, are operational. This energy will be able to meet the
power shortage throughout the country. If industries work at their full capacity, production
will be higher and so per capita income will increase and inflation will be neutralized.
3. With the help of controlled nuclear explosions, artificial dams can be made. In fact for
building a dam there should be two huge mountain walls enclosing a deep valley just near
the course of a river. These conditions are not available at all the places. So with the help of
controlled nuclear explosions mountains can be blown up. This can also help in laying
roads in the mountainous areas. In fact, some of the borders of India have mountainous
terrain and the movement of the army is quite difficult. So even for the sake of national
security it is necessary to have roads in those areas.
4. With the help of radiation the shelf life of vegetables and fruits can be increased. In the
tropical countries like India, it is necessary that the perishable fruit stuffs are preserved for a
long time. Radiation can check the sprouting of onions and potatoes which are much in
demand in foreign countries. Similarly fruits like bananas and mangoes which have much
export potential can be preserved for a very long time. The texture and taste of the fruit do
not undergo any change.
5. Nuclear technology can also be harnessed for medical purposes. It is said that radioactive
iodine is used for detecting the disease of the thyroid glands. Similarly, India of U.N.
experts, radiated vaccine which can immunize sheep from lungworm disease, which used
to take a heavy toll of sheep every year.
6. Properly processed nuclear fuel is also used for artificial satellite in space. Weather
satellites can predict cyclones and the rainfall with extreme accuracy. Communication
satellites can help in conveying the messages to very long distances. In a huge country like
India, communication satellites are necessary.
7. Radiation is also used for preparing the mutant seeds. Many varieties of rice and some
cereals have been prepared at Tarapur laboratory. This will increase our agricultural
production and help India to become economically better off. So for India it is necessary to
make peaceful uses of nuclear energy.
Answer the following Question:-
a. Write a summary of the following passage in 80-100 words
b. What are the benefits of Nuclear energy?
c. Mention the effectiveness of Radiation
Answers
Answer:
a) the nuclear power plant is one of the most advance step of world as it is good and bad both.there are 8 - 9 countries that have nuclear weapons like China, Russia, USA, France, Pakistan e.t.c. Many countries are developed country who can meet their needs but developing countries like India , Pakistan have not sufficient capital to meet their needs so, they use nuclear for - production of energy, agriculture helps .In India there are mainly two nuclear station - 1 . tarapur, ranapeatap sangan . some countries use nuclear for self defense while some for attack purpose, in India thorium is found in abundant percentage so it is also used for artificial satellite ,energy Production, agriculture purpose etc.it has many disadvantages also like bad effect of radiation.The texture and taste of the fruit do
The texture and taste of the fruit donot undergo any change.Weather
Weathersatellites can predict cyclones and the rainfall with extreme accuracy. Communication
Weathersatellites can predict cyclones and the rainfall with extreme accuracy. Communicationsatellites can help in conveying the messages to very long distances
2) nuclear energy helps in production of energy, agriculture purpose, medical purposes,etc.
3)
Radiation is also used for preparing the mutant seeds. This will increase our agricultural
production and help India to become economically better..
hope this answer is clear to you
