BETTER THAN THE BEST
By Ashwini
Bhatnagar
"YES, Prime Minister.
Thats what I said. What else can you tell the Prime
Minister?", Atomic Energy Commission Chairman R.
Chidambaram replied with a chuckle to a question as to
what his response was when he was told about the ( then)
proposed nuclear tests in Pokhran. "It took us a
month to get everything in place," Chidambaram
continued with a twinkle in his eye. "It went off
perfectly. In fact, all the parameters were exactly as we
had calculated before we went for the actual
detonations." The quiet confidence of the man who
holds one of the most sensitive jobs in the country has
to be seen to be believed. "The vision of a nuclear
India that Homi Bhabha and Pandit Nehru had has been
fully realised," he says. "We are now looking
at the future. Our immediate task is Vision 2020 and
through it we have to prepare for the next century."
Chidambaram has reasons to look back with
satisfaction. There is , perhaps, no other sector in the
country that has in its "quiet and efficient"
way delivered what it had promised itself and the
country. India is today firmly established on the world
nuclear map as a power to reckon with, despite the
handicap of restrictions placed by the West. In a way,
these restrictions/sanctions which came about after India
did Pokhran I in 1974 have helped the atomic energy
scientists and engineers to look within and develop their
own systems and equipment. It takes some time to digest
the statement made by Director of Bhabha Atomic Research
Centre Anil Kakodkar when he was asked whether the
material made inhouse was comparable to international
standards. " Comparable? We are the best. They now
have to use us as a bench mark," he replied
nonchalantly.
But, as Chidambaram is
at pains to stress, Indias nuclear programme is not
all about the Bomb only. Of course, the Big Bangs which
have so far taken place have been much talked about
because of the political and military implications which
they entail. But the fact
remains that they are but a very small part of the total
scientific and materials output of the institutions under
the control of the Atomic Energy Commission. For example,
the biggest establishment under the charge of the
Commission -- BARC, located at Trombay near Mumbai-- has
a workforce of about 20,000 skilled and semi-skilled
personnel. Of these, about 4,500 are scientists and
engineers-- men and women who have highly specialised
skills in different branches of science and technology.
According to Kakodkar, "Though BARC is primarily a
technology institution and has distinguished itself in
technology development, you name a discipline in science
and engineering and you will find a group working in it
at BARC. It is a goldmine. In many of the basic research
areas, BARC is rated as one of the best institutions in
the country. For example, in physics we are rated as the
third best institution, way above many of the
universities and specialised research centres in India.
For a technology institution to achieve this level of
competence is rare."
Kakodkar also emphasises
that BARC is not about Rand D only. "Here we have R
&DDD; meaning research, development, demonstration
and deployment. There is, of course, a very strong
emphasis on basic research. But that research has to be
developed into technologies which not only have to be
demonstrated as workable but also deployed in specific
areas of utilisation. This is our credo at BARC. And for
this to happen,we have the trinity-- energy, materials
and processes-- which lead up to the end result."
The focus and the buzz word
nowadays, therefore, is energy or nuclear power.
"This is our top priority, nothing else, " says
Chidambaram. "If we have to take the country
forward, we need energy. It is a critical input for
ensuring a better life for our people. But where is the
energy? Our per capita energy consumption is seven times
less than the world average. And if we want to raise it
sufficiently, we will have to turn to nuclear power.
There is no other alternative. As much as 73 per cent of
the total power is thermal. Hydro generation is 24 per
cent and nuclear just 2.6 per cent. However, our coal
reserves are going to last for 90 years and oil for 21
years. Gas reserves are good for another 30 years or so.
So, we have to turn to an inexpensive and sustainable
source of electricity --- nuclear power. Thirty per cent
of the total power generation in Japan is from nuclear
power stations. In the USA, 20 per cent comes from this
source. India, too, will have to adopt it if it wants to
better the lives of its citizens."
It is, therefore, not
surprising that throughout the five-day interaction with
atomic scientists and engineers at BARC organised by the
NUJ School of Journalism and Communication at Trombay,
journalists were exposed to the potential of the atom in
turning around the economic condition of the country. The
first-hand experience of the facilities and the
transparency of approach displayed by officials and
scientists showed the earnestness of the establishment in
harnessing the power of the atom for peaceful and welfare
purposes.
This is
evident from the fact that plans are already afoot to
phase out uranium as fuel for reactors and replace it
with thorium. The genesis of the programme can be traced
back to 1954 when Homi.J Bhabha drafted the three-stage
nuclear power programme which was aimed at using our
natural resources of uranium and thorium. It required the
building of pressurised heavy water reactors which used
natural uranium as fuel for producing power and plutonium
fuel in the first stage. The second stage entailed
building of fast breeder reactors using plutonium as fuel
and producing electricity and more plutonium and uranium
233. The third stage was thorium-based reactors.
In order to attain
technical capability in managing nuclear power plants
indigenously, two boiling water reactors were set up at
Tarapur on a turn key basis. The Tarapur Atomic Power
Station (TAPS) became operational in 1969 and India came
on the nuclear power map. Subsequently, two prototype
heavy water reactors were built at Rawatbhatta
(Rajasthan) with Canadian help.These commenced commercial
production in 1972 and 1980. They were followed by two
more similar reactors at Kalpakkam near Chennai in 1984
and 1986. They were designed, built and operated entirely
by our engineers and scientists.
After attaining self-reliance in setting
up pressurised heavy water reactors, two 220 megawatt
capacity reactors were set up at Narora. They were
commissioned in 1989 and 1991. Two more such plants were
built and commissioned in 1992 and 1995 at Kakrapar
(Gujarat). The country has now a installed capacity of
1840 MWe. Construction work is in an advanced stage at
four 220 megawatt reactors, two each at Kaiga (Karnataka)
and Rawatbhatta. The Kaiga station will provide
electricity to the southern grid while RAPS 3 and 4 will
supply power to the northern grid. The Kaiga plant is
expected to go critical shortly.
Another ambitious plan
is a joint venture with Russia for construction of a
nuclear power unit consisting of two pressurised water
reactors of 1000 MWe capacity each. Moreover, with a view
to realise economy of scale, a large 500 MWe heavy water
reactor system has been designed. The Department of
Atomic Energy is all set to construct two such units at
Tarapur. The hectic activity on the power front is aimed
at producing 20,000 MW of power by 2020 AD from the
present production of 1840 MW. The quantum jump will come
as these units, besides others which are at the planning
stage, go on stream over the next 20 years or so.
The picture looks pretty
rosy as "we prepare now to meet energy requirements
for the next two or three centuries." But nuclear
power is risky. Radioactive waste management has raised
the heckles of environmentalists the world over. In
America and many parts of Europe, it is a major issue.
Radioactive waste, in fact, is a dreaded word since it is
claimed that it can alter genetic material among humans
besides causing diseases like cancer. Moreover, it has an
highly injurious impact on the environment. Remember
Chernobyl?
P.K.
Wattal, Head, Process Development Section, BARC,
pooh-poohs the possibility of nuclear waste causing
sleepless nights in India. "The Americans had it
coming. They used to carelessly dump radioactive
material. They made a mess of it and hence the public
outcry. They had no policy on waste management. But
things have been different in India from the very
beginning. As early as 1962, we started a waste
management programme and we have been following it
scruplously. We are a government agency and we owe it to
the people, unlike many private firms in the West."
According to Wattal, Indias waste management
programme is virtually fail-safe. It is a three-phase
programme and is used for high-level (radioactive) waste.
The first phase is calcination followed by vitrification
in which the waste is immobilised. Then comes interim
storage. This entails storing the waste in specially
demarcated and built storage spaces. Finally, it goes to
ultimate storage in geological repositories. Wattal
claims that there is virtually zero possibility of waste
finding its way back to the eco system once it has been
immobilised and stored in the manner prescribed above.
" The removal, movement and storage is done under
the most stringent conditions applicable anywhere in the
world. Our safety record is also way above that found
anywhere else internationally.
But, what about a
disaster like Chernobyl? Says Kakodkar, "It
cant happen in India. After the incident happened,
we formed a review committee which was chaired by me. We
assumed that everything will go wrong. The core heat goes
up, systems do not function, power is off etc. My
colleagues said that we dont have to assume that
all our safety systems go wrong simultaneously. Some
things will work. But I told them to assume that nothing
works and we have a problem. Can we manage it? We went
into all the details, looked at our power plant
designs,inventory, systems etc and reached the conclusion
that Chernobyl-type situation is ruled out. We have
incorporated certain design features in our reactors
which are based on natural laws and will work even if
there is no power/battery standby or human intervention
is not possible. They will cool down the reactor and the
accident will have no impact outside the plant
boundary."
Apparently, therefore, nuclear power is
safe. "It is perhaps safer than anything else,"
says Wattal, "For example, coal-run thermal stations
pollute the environment more than a nuclear plant does.
In fact, it hardly pollutes. Secondly, fly-ash is a big
problem in thermal plants. The quantities are huge. Where
do you take it all? Our waste, on the other hand, is
hardly noticeable. Nuclear waste in India is just 75
metric cube per year and as we go on the thorium-based
cycle, it will come down further. Lastly, there is no
evidence whatsoever that there is radiation around the
areas which have a nuclear power plant. We monitor a
30-km area around our plants for radioactivity and the
results are well below the safety limits prescribed
internationally. Nuclear power is absolutely safe."
KSParthasarathy, Secretary, Atomic Energy Regulatory
Board, points out that the safety standards prescribed
and "vigorously" enforced in India are
substantially above the safety norms being followed in
the West. "We want the process to be absolutely
safe. We have deliberately kept the regulatory aspect
tough as nuclear power is as vital for us as human and
ecological well-being."
We are, in fact,
path-breakers in safety standards as we are in power
plant design, fabrication and running. India is also the
world leader in radio isotope production and in many
applications in the field of medicine and medical
equipment. Canada and the USA, our original benefactors
in nuclear technology, are now looking at India for
supply of isotopes to them. BARC-developed technology is
used by hospitals around the country to treat one million
patients every year. There is, therefore, more to the
atomic energy programme in India than just the Bomb.And,
in most of these aspects too we are the best in the
world.
