Leaking Liability Strategically

The issue of India's Civil Nuclear Liability has been a contentious one, with charged reactions from all sides. The principal points of the law, as it now stands, are a maximum liability cap of Rs. 2500 crores, in event of a disaster, to the operator, which in this case would be Nuclear Power Corporation of India Ltd(NPCIL) and GoI, plus a clause that allows NPCIL to subsequently sue the nuclear supplier for damages. It is this tiny clause that has deterred foreign commercial interests from venturing into nuclear trade with India - especially in a post Fukushima world.

The Indian state, with its nuclear establishment, under international and US pressure, is pushing for a dilution of India's liability clause to open up India's nuclear energy sector for commercialisation;  the foreign suppliers  are also keenly eyeing investment opportunities with India's ambitious goals of expanding its civil nuclear facilities, but can only afford to risk business ventures if the nuclear opportunity is offered risk-free - i.e. without the baggage of an eventual supplier liability - even if they were responsible by providing defective technology that caused a nuclear disaster.

Such a dilution was staunchly opposed by anti-nuclear activists, especially in pockets around the upcoming nuclear facilities, since this could potentially lead to a weakening of quality controls from a non-liable supplier and thus pose an increased risk of future calamity. Also, sections of India's civil society voiced their opposition based on the horrific human tragedy and fiasco, played out in the aftermath of the Bhopal chemical disaster; they were unwilling to let the Indian tax payers take full financial responsibility for any future and potentially a more dangerous nuclear disaster caused by a liability-shielded supplier's negligence and failure. The dilution issue also faced partisan reactions with nationalistic jingoism from right to expressed opposition from the left [See a recent mix of reactions here].

It is important to note that the recent unfolding of corruption charges against Zio Podolsk for supplying substandard equipment to nuclear facilities - both Russian and foreign - is part of the same larger concern of what can and will play out without a strictest liability clause that force adherence to quality control. Agreement for Units 1 and 2 of Kudankulam, between India and Russia, predated our Civil Nuclear Liability and was therefore exempt from it. One might argue that a better system of checks and monitoring, mandated if Russia were functioning within a tight nuclear liability clause, would have probably lead to a less compromised system with fewer substandard parts than were probably supplied to Kudankulam.

Now, this was the current state of affairs - or so I thought. Behind the scenes, however, a whole different drama had already played out. I chanced upon this script from WikiLeaks.

There are many serious and grave revelations:

1) It appears that Indian officials are willing to compromise the liability issue and facilitate free nuclear commerce with the US provided they receive strategic cooperation on the issues of reprocessing and enrichment. India would then ratify the Convention on Supplementary Compensation for Nuclear damage(CSC), despite this not being a recommended choice for the nation. India's signing the Safeguard Agreement with IAEA also was conditional to progress on nuclear reprocessing and enrichment.

2)The officials reiterated their commitment to the letter of intent, already been signed with the US, for two nuclear parks with a combined capacity of 10,000 MW. The site explorations were concluded although the sites not finalised.

3)There was a strong push to encourage participation of private sector in power generation and management and also for partnerships between Indian firms and  US suppliers - to keep the cost of nuclear energy competitive.

The need for concern is strong. The civil nuclear liability issue, that provides a safety net for Indian citizens, in case of a nuclear event, is being used as a bartering chip for so called 'more important' strategic goals. That this happens behind closed doors, and with far fetched ambitions for the nuclear energy sector - without media participation and far from public eye, is a cause for further worry. That private Indian vendors and public-private-partnerships are encouraged, takes the exercise even further away from the realm of safe-and-secure, with increased difficulty for any vigilant monitoring or supervision of quality control - necessary for the complex and risky nuclear industry. And thus to systematically derail national interest and safety of its citizens by weakening the issue of liability,  under such circumstances, is just sheer madness. Beware!

Death-ly Competition: Choosing between Nuclear and Fossil Fuels


Yesterday, the world mourned on the 27th anniversary of the Chernobyl Disaster - and things are still not 'normal' in the disaster effected zone. In fact,  many things will never get fixed, or normal, or reverted to prior-to-accident-state - some 30,000 sq. kms which will remain contaminated actively radiating till 2090 - polluting soil, air, water, and all living things and also killing them.


In this context, the efforts of nuclear lobby took an absurd and macabre turn with this recently published paper. The authors calculated deaths prevented by production of nuclear power, instead of power from fossil fuels - which would generate sufficient air pollution to choke 1.8 million people to death. This estimate is a cumulative of nuclear power generated throughout history and strongly advocates its future expansion, despite the Chernobyl and Fukushima disasters, to  prevent a purported 7 million deaths by mid-century. It is curious that the authors compared two hazardously polluting thermal technologies, run on nuclear and fossil fuels, to declare nuclear power a winner - and this dubious win is also a suspect. It is more surprising that a journal like Environmental Science & Technology decided to publish this article, since competing two flawed and inviable technologies cannot be used to promote scientific merits of either.

However, if one were to indulge in such a bizzare exercise of account keeping deaths, it is also necessary to track all dead, or dying and generations yet to be born who will die, unnaturally, because their ancestors, in the distant past, were exposed in nuclear disasters. Between 1986-2004, an estimated 985,000 died mostly due to cancer from Chernobyl exposure. By 2011, this number had risen to 1.5 million. Yes.. it is true that these estimates are statistical , but these are now statistics of large numbers and well above average mortality expectations (for example the cancer rates in cleaning crew is three times higher than rest of the population). Remember that for every death due to radiation exposure there are at least twice as many cases of cancer - with their untold misery, pain and suffering. And, all this before we reach the half life of 137Cesium which is 30 years.  It takes three decades for half of the radioactive 137 Cesium to have decayed and harmed everything in its path...and between five to seven such half lives before the radioactive effects become sufficiently small. Thus the radioactive contamination of 137 Cesium will continue decaying and damaging ad infinitum, as will also the other radioactive isotopes of Strontium and Plutonium.


While it might be too early yet to observe the health damage in the exposed population in Japan, recent studies seem to indicate that the Cesium levels from Fukushima disaster could be as much as 20-30 times higher, and might contribute to a thousand times more deaths than predicted. In fact, the effect of irradiating the food chain will contribute and build radiation poisoning in all species. Thus, the total future death toll from Fukushima disaster should also be subtracted from the estimated  'lives saved' in this paper.


A question for the authors is : when a single major nuclear accident, like Chernobyl, can wipe off the canvassed advantage of the historically-compounded nuclear power, over coal, are they sure of their conclusion - of saving lives with nuclear energy, and further advocating a global nuclear future? Especially when the death toll from Chernobyl and Fukushima will continue to increase on time scale much much longer than our lifetimes, or of these authors writing this ludicrous paper.

Also, the authors calculate that IAEA's projected increase in nuclear energy capacity till 2050 will save a further maximum of 7 million lives, forgetting to scale alongside the direct additional risk of serious future nuclear accidents. Are ready to risk four times as many Chernobyls and Fukushima, with their un-countable future deaths and health impacts and the vast irreversible environmental costs, to allow a future nuclear race? Can we, as a human race sustain or even survive this?

Don't get me wrong - I am definitely not arguing in favor of highly polluting, hazardous, huge GHG emitting fossil fuelled thermal power plants. But I staunchly oppose the pitching one disastrous technology against another to proclaim, unethically, a winner. For this is what the authors do - use incomplete calculations to make strong and wrong inferences, to lobby for the future of nuclear energy, forgetting, that nuclear accidents are inseparable components of such complex and unsafe technology and there can only be losers in such  "death-ly competition".
