Sri Lanka is flirting with nuclear power
Sri Lanka is becoming a power hungry nation. Several coal power plants with a total generation capacity of 3,200 MW are on the anvil. The country’s new energy minister, Champika Ranawaka, wants a nuclear power plant by 2025. That’s a sure sign of change To be fair Ranawaka is not the first proponent of nuclear power.
A year ago, at an annual meeting of the International Atomic Energy Agency, the country’s minister for science and technology, Tissa Vitarana, was convinced that nuclear power is a must for Sri Lanka. He said that thorium deposits in Sri Lanka can serve as an energy source. On September 5, the English newspaper Daily Mirror reported that the minister has invited Indian scientists to conduct a feasibility study on thorium deposits in the southern coastal belt.
It seems these ministers paid short shrift to economics as well. It takes more than a decade to construct a plant and it costs billions of dollars. Researchers inform that Sri Lankan thorium deposits will not last more than 60 years. So there will be added financial burden if thorium has to be imported from Russia or elsewhere.
Environmental hazards of thorium mining are also well known. How will Sri Lanka handle large quantities of radioactive waste produced in the process of thorium mining? Looks like Sri Lanka has not learnt much from India’s experience with nuclear reactors.
It is important for countries developing nuclear power to consult their neighbours. India did not do so when it developed nuclear stations in the southern tip. A disaster in these plants might affect Sri Lanka also. And southern part of India will be threatened if there is a disaster in a Sri Lankan plant.
Recently, the nuclear industry has seized on climate change concerns to override environmental safety issues. The industry claims nuclear power is an obvious solution because nuclear reactors emit virtually no CO2 at the point of electricity generation. Scientists have busted this myth. The preparation of uranium for the reactor involves a CO2- emitting processes.
Then there is the issue of liability. Nuclear equipment suppliers expect an immunity clause, as can be seen in the case of other countries, including India. Such clauses either limit liability to a ridiculously low amount and/or immunise private equipment manufacturers, service providers altogether from any liability arising from a meltdown or nuclear disaster.
It is hard to understand why Sri Lanka is even considering nuclear power when it has sustainable sources such as wind, solar and small hydro energy. Hope ministers don’t forget energy sovereignty when dealing with energy security.
