11. Read the following passage and answer the questions given at the end :
(1 ´ 16 = 16)
Former chairman of the Atomic Energy Commission (AEC), Dr. Anil
Kakodkar, said that in the backdrop of the disaster at the Fukushima nuclear
plant in Japan, the design of the Jaitapur nuclear power plant (JNPP) being
planned in Ratnagiri district of Maharashtra, should be strengthened.
The eminent scientist said that unlike Fukushima, the Jaitapur plant will be
located at a considerable height above sea level. “India is in a less seismically
active zone as compared to Japan. Therefore, the probability of massive
earthquakes is pretty low. Yet, I would suggest that the plant be designed to
withstand the worst scenario to prevent any repetition of the Fukushima
disaster,” he said.
Kakodkar was reacting to the ongoing crisis at the ill-fated Fukushima nuclear
plant in Japan after it was struck by a massive earthquake and flooded by the
resultant tsunami. The cooling system of the plant malfunctioned due to
flooding of the generators, which led to radiation leakage and subsequent
evacuation of residents of the area.
Kakodkar pointed out the requirement for large quantity of water for cooling
at a nuclear plant and sea being the largest water body, seaside makes an
ideal location for such plants. He noted that India already has three nuclear
plants in Kalpakkam (Tamil Nadu), Tarapur (Maharashtra) and Kakrapar
(Gujarat) near the seaside.
“Kalpakkam was hit by the tsunami in December 2004, but the reactors were
safe. In India, safety factor is always the top priority while designing a nuclear
plant,” he said. However, Kakodkar warned against being complacent and
called for learning from the tragedy in Japan.
“In the nuclear industry, we share our experiences to improve our designs and
increase our safety standards. The Fukushima incident should be analyzed in
detail by Indian nuclear engineers to better the designs of the Jaitapur plant”
he said.
Dr. A Gopalakrishnan, former chairman of the Atomic Energy Regulatory
Board, stressed on adoption of maximum safety standards while designing
nuclear plants in India. “The chances of a tsunami hitting Jaitapur are
relatively less. Jaitapur comes under a relatively seismically less active zone,
so the chances of a major earthquake are low,” he said.
Kate Hudson, head of the Campaign for Nuclear Disarmament in London, says
building nuclear plants on the shore line, like Japan or Britain do, because of
the need for water passing through the station for cooling purposes, may lead
to a very dangerous situation in case of a natural disaster like tsunami or a
rising water level. Valery Petrosyan, a UN expert on chemical safety, has
joined the chorus of voices admitting that there is real cause for concern about
what is happening at the Japanese plant. However, Dr. Richard Philips from
the School of Earth and Environment at Britain’s University of Leeds says
Japanese nuclear facilities are very well prepared for any natural disasters
and the catastrophe is unlikely to happen.
