The many Paths to Energy Security The Nuclear Path I have been saying for 2 decades now: “Nuclear Energy is an inevitable option to satisfy India’s future energy needs” The Renewable Path “Today, America faces grave challenges in the field of energy – from the gathering storm of global warming to a dangerous addiction to oil that jeopardizes our national and economic security…. An energy future based on abundant and clean renewable resources is not only urgently needed, but achievable” And then, of course, Efficiency
The Fourth assessment report of the Intergovernmental Panel on Climate Change(IPCC) concluded from direct observations of changes in temperature, sea level, and snow cover in the northern hemisphere during 1850 to the present, that the warming of the earth’s climate system is unequivocal. The global atmospheric concentration of greenhouse gases (GHG) has increased from a pre-industrial value of about 280 ppm to 379 ppm in 2005. Multi model averages show that the temperature changes between 2090 -2099 relative to 19801999 will range from 1. 1 to 6. 4°C and sea level rise from 0. 18 to 0. 59 meters. This large uncertainly derives partly from the modeling uncertainties and partly from the uncertainties in the global energy use scenario.
From the point of view of India, The mitigation technologies to counter the Climate Change Threat (nuclear, renewables, efficiency), coincide with the technologies we need to counter the depletion of fossil fuels. The drive towards nuclear in India (and China) is because of surging energy demand while the nuclear renaissance in the developed countries is also driven substantially by the climate change threat.

Solar Power Global production of Solar Photovoltaics (PV) cells increased 51% in 2007 to 3, 733 Megawatts. Europe – led by Germany – surpassed Japan in solar cell manufacturing (1, 063 MW) in 2007. Germany remained the world leader in Solar PV installations, accounting for almost half the world total in 2007. Spain ranked second…. As in Germany, the Spanish market is driven by a strong guaranteed price for PV electricity…. . China raced past the U. S. for PV cell manufacturing (for 2006) …. Most PV cells made in China are exported to Europe. Worldwatch Institute, May 14, 2008 The cost is still high. The Central Government in India offers a generation-based incentive upto Rs. 12 (25 U. S. cents) per k. Wh unit to private sector players for setting up grid-interactive solar plants of a capacity of one MW and above. Out of 9147 MW Grid-Interactive power added from renewables in the last 5 years, wind power accounted for 7273 MW. There is a ‘Indian National Solar Mission’ proposed in the National Action Plan on Climate Change.
After extensive experimental work and computer simulations got done by a Working Group set up by PSA’s Office, during the last three years, starting with the technology developed by BHEL over the past two decades, the feasibility of IGCC process for high ash Indian coal has been established. This leads to cleaner and more efficient use of coal. BHEL and APGENCO have signed an agreement recently to set up a 125 MW plant at Vijayawada using IGCC technology
Ø Three-stage Nuclear Power Programme (Sustainable Development of Nuclear Energy would inevitably require closing the nuclear fuel cycle. The same limited amount of uranium has a 600 – times higher energy potential, if the fuel cycle is closed with thorium). Ø Spin-offs in Agriculture, Medicine and Industry (In India, nuclear technology has acted as a catalyst for nucleating many other high technologies from parallel processing supercomputers to welding) Ø Development of Major Facilities for Research (research reactors, particle accelerators, synchrotron radiation sources, superconducting tokamak, advanced instrumentation)

“U-TURN FOR NUCLEAR OPPONENTS” In a landmark article for the left-leaning Independent newspaper. New Statesman Writer Mark Lynas said the anti-nuclear campaigns of the past “will come to be seen as an enormous mistake for which the Earth’s climate is now paying the price”. Stephen Tindale(who ran the UK branch of Greenpeace from 2000 to 2005 told the newspaper, “It was like a kind of religious conversion. Being anti-nuclear was an essential part of being an environmentalist for a long time. “He now claims that ‘It’s actually quite widespread, now, this view that nuclear power is not ideal but it’s better than climate change. ” Tindale’s announcements echo that of Patrik Moore, one of the Canadian founders of Greenpeace. Moore now advocates the use of nuclear power and large hydro for low-carbon power generation… 23 February 2009 – World Nuclear News. James Lovelock, Eminent Environmental Scientist and proponent of the Gaia Hypothesis, was the earliest to this U-turn in 2004. To reverse a longstanding (extreme) position requires high-integrity and character.
Italian nuclear moved forward at summit 24 February 2009, World Nuclear News The 27 th Franco-Italian summit saw delegations of ministers from both sides (conclude) a new agreement on cooperation in nuclear energy – Electricite` de France and Enel partnership to conduct feasibility studies towards “at least four EPRS in Italy”. The Step is among the biggest that Italy has so far taken towards a re-employment of nuclear energy, …. (after) Silvio Berlusconi’s Forza Italia party put a return to nuclear energy in its manifesto.
“Expanded use of nuclear technologies offers immense potential to meet important development needs. In fact, to satisfy energy demands and to mitigate threat of climate change – two of the 21 st century’s greatest challenges – there are major opportunities for expansion of nuclear energy in those countries that choose to have it”. from Report prepared by an independent Commission at the request of the Director General of the International Atomic Energy Agency - 2008
§ The use of uranium in the once-through mode will enable the use of only a small fraction of the available uranium resource. § Fast reactors used in the closed fuel cycle mode provide the option for the full exploitation of the natural resources. This is further enhanced by inclusion of Thorium in the closed nuclear fuel cycle. § The closed fuel cycle, in comparison to the once-through cycle, reduces the volumes of waste requiring treatment and disposal. § With the closed fuel cycle, Nuclear is near-Renewable. § Then there is Nuclear Fusion.

Mechanisms for overcoming Major weaknesses in Technology Development and Delivery (Industrial Development vs Rural Development-Climate Change Response will involve both) Through innovative Interaction Interfaces for Industrial Development (e. g. CAR: Core Advisory Group for Automotive Research) and through ‘Directed Basic Research’ Research CAR & Ru. TAG are initiatives of the PSA’s office Development Delivery Through Innovative Technology Delivery Systems for Rural Development (e. g. Ru. TAG)
What is ‘Directed Basic Research’ Research In its execution, and in the requirement of no other deliverablesthan knowledgegeneration, it is no different from conventional basic research. So the University academics should be comfortable with this kind of research. The selected areas are determined in a national perspective, just like in Technology. Foresight. ‘Directed’Basic Research may be in an area where the knowledgegenerationwould benefit. Indian Societyin the long term or it may be in area where the results of the , research would benefit Indian Industry or our strategic interests in the long term, particularly in cross disciplinary technology areas.

For India to become a ‘developed’ country, the per capita electricity consumption has to increase manifold. And nuclear has to play an important role in this increase.
