Say no to nuclear power and risk future energy shortages and adverse climate
By Prof. Kirthi Tennakone
Sri Lanka is planning to initiate nuclear power generation after a long delay––a prudent decision to secure future energy demand and reduce emissions. However, some parties have expressed skepticism that nuclear energy is unsuitable for Sri Lanka, saying it poses a risk of environmental radioactive contamination in reactor meltdowns and waste disposal.
It is true that Madame Curies’ laboratory in a suburb of Paris, where she meddled with truckloads of the uranium mineral pitchblende, continues to be lethally radioactive and beyond remediation. This was the first incident of radioactive seepage, which happened at the dawn of nuclear energy more than one hundred years ago. The situation is vastly different today. Since the advent of commercial reactor technology in the early 1950s, only two major mishaps have occurred; Chernobyl in 1986 and Fukushima in 2011.After these accidents, reactor designers made improvements to ensure safety.
The death rate associated with energy production, in accidents and environmental pollution stands lowest for nuclear power.
Nuclear power has also been opposed on the grounds that it leads to weapon development, war and acts of terrorism. These social ills emerge in the absence of political will to ensure democracy, fairness and equity rather than from nuclear power generation.
Nuclear energy is a clean and zero emission source and the most economical in terms of energy derived per unit weight and volume of fuel. A uranium fuel pellet about the size of a lozenge and weighing 10 grams, generates the same amount of energy as one ton of coal.
Despite the above facts, the public’s aversion to nuclear energy stems largely from unsubstantiated fear mongering and not being informed enough to realize it is a universal and natural source of energy, not something granted by the devil. Nuclear energy is fascinating. Just like solar energy, its primary origin is celestial. You will reconsider its virtue after learning what it is and how it came about.
What is nuclear energy?
One of the greatest achievements of modern science has been the revelation of the atomic structure of matter. Centuries of dedicated work by chemists and physicists disclosed matter is made out of some ninety odd elements, which cannot be broken-down further into freely existing components. And each element is constituted of atoms characteristic of it. An atom has a nucleus, where positively charged protons and neutral neutrons are glued together to form a ‘ball’ and surrounded by electrons to balance the positive charge. Sometimes, a heavy atomic nucleus containing protons in excess of a certain limit, disintegrates on its own, emitting ionising radiation – the process known as radioactivity. The radioactivity of a chemical element indicates an instability of the atomic nucleus carrying stored energy.
In December 1938, two physicists, Lise Meitner and Otto Frisch, working in Berlin, made a startling discovery changing the world forever. They bombarded uranium, the heaviest chemical element found on earth, with neutrons, thinking that would enable them to create artificial elements even heavier than uranium, but observed something else. When a neutron hits the uranium nucleus it broke into two lighter nuclei and a few neutrons, releasing an excessive quantity of energy. Physicists are extraordinarily clever and immediately realised the potential of the discovery to initiate a chain reaction using uranium and derive energy either slowly or explosively. The idea was practically implemented a few years later. Inventing nuclear reactors to save the planet and atomic bombs to destroy it. Now is the time to promote the first and ban the second.
What is the primary source of nuclear energy?
Fuels store energy in an invisible but extractable form. Firewood, coal, petroleum and uranium are fuels. Nature allows only transfers of energy from one agent to another, not the creation out of nothing. The common fuels got their energies from sunlight harvested by green plants, recently or millions of years ago. However, uranium has nothing to do with the sun.
Uranium occurs in the earth’s crust, notably as the mineral pitchblende. How was uranium so rich in energy, produced? The answer to the question bears on the general issue of the origin of chemical elements.
All the hydrogen and a good portion of the helium in the universe were produced three minutes after big bang. Later, a series of reactions occurring inside stars, starting with the fusion of hydrogen and helium nuclei, produced elements lighter than iron. A uranium nucleus has 92 protons and 146 neutrons, assembling them together requires an extremely energetic environment with an intense flux of neutrons. Such extreme conditions happen when a massive star explodes as a supernova, two neutron stars collide, or a black hole begins devouring a star. These events, not uncommon in the universe, produce very heavy elements, including uranium and gold (loved by many more than uranium) dispersing them all over the interstellar medium to be picked up by planets during their formation.
Nuclear energy is not renewable, but the world has a good supply of uranium. We say solar energy is renewable, because its availability over human scales of time is virtually unlimited.
Renewable energy versus nuclear energy
Despite strong emphasis and major advancements in power generation using renewables; solar photovoltaic, wind and hydroelectricity; around 80 percent of the world’s current energy demand comes from fossil fuels. Projections predict reductions expected via renewable usage would be of the order of 2-3 percent per year in the next decade. The deployment of renewable power generation facilities also consumed fossil fuels. Converting silica to silicon and making solar cells, panels and installation of supporting structures made out of iron require fossil fuel, which cannot be replaced by pure electricity. Similar constraints arise in the commissioning of wind and hydroelectric projects. Additionally, renewable energy supplies are intermittent and affected by climate variation. We know very well the problem of hydroelectricity during times of poor rainfall and draught.
Renewable energy generation systems have inherently low efficiencies and involve the utilisation of large land areas and huge quantities of materials. When attempts are made to meet a significant portion of the increasing energy demand using renewables, the constraints become increasingly severe.
A nuclear reactor of capacity 1000 megawatts needs a land area of about three square kilometers. Whereas a solar cell complex of the same capacity, covers at least 20 times more land and a wind farm 700 times. Offshore wind farms, though a good option, have a shorter operational time and higher maintenance costs compared to nuclear reactors. Other renewable energy generation systems also lead to similar constraints.
Nuclear energy and hydrogen
Today, the world focuses much attention on green hydrogen, the cleanest fuel able to decarbonise the transport sector and eliminate fossil fuels in manufacture of fertilisers, steel, solar cells and a host of other essential commodities. Production of green hydrogen via splitting water is energy intensive. Renewable energy exploited to its limits may not suffice for production of sufficient hydrogen. Nuclear energy is undoubtedly a viable alternative.
A real problem with renewable energy is the escalation of constraints when they expand to a level sufficient for the complete elimination of fossil fuels. It is hard to predict how the advancements in renewable energy will progress in the coming years.
Meeting the ever-increasing energy demand and phasing out fossil fuels to avert global warming is most unlikely to be achieved without supplementing of renewables with nuclear energy.
Building nuclear power plants is costly and time consuming. Nevertheless, in the light of the gravity of energy and climate crisis, no country can afford to ignore nuclear energy. Sri Lanka needs to embark on nuclear energy at least in a small way and plan for the future.Otherwise, in decades and years to come, the repercussions of saying no to nuclear energy could be the same as banning chemical fertilisers!

Ranking public services with AI — A roadmap to reviving institutions like SriLankan Airlines
Efficacy measures an organisation’s capacity to achieve its mission and intended outcomes under planned or optimal conditions. It differs from efficiency, which focuses on achieving objectives with minimal resources, and effectiveness, which evaluates results in real-world conditions. Today, modern AI tools, using publicly available data, enable objective assessment of the efficacy of Sri Lanka’s government institutions.
Among key public bodies, the Supreme Court of Sri Lanka emerges as the most efficacious, outperforming the Department of Inland Revenue, Sri Lanka Customs, the Election Commission, and Parliament. In the financial and regulatory sector, the Central Bank of Sri Lanka (CBSL) ranks highest, ahead of the Securities and Exchange Commission, the Public Utilities Commission, the Telecommunications Regulatory Commission, the Insurance Regulatory Commission, and the Sri Lanka Standards Institution.
Among state-owned enterprises, the Sri Lanka Ports Authority (SLPA) leads in efficacy, followed by Bank of Ceylon and People’s Bank. Other institutions assessed included the State Pharmaceuticals Corporation, the National Water Supply and Drainage Board, the Ceylon Electricity Board, the Ceylon Petroleum Corporation, and the Sri Lanka Transport Board. At the lower end of the spectrum were Lanka Sathosa and Sri Lankan Airlines, highlighting a critical challenge for the national economy.
Sri Lankan Airlines, consistently ranked at the bottom, has long been a financial drain. Despite successive governments’ reform attempts, sustainable solutions remain elusive.
Globally, the most profitable airlines operate as highly integrated, technology-enabled ecosystems rather than as fragmented departments. Operations, finance, fleet management, route planning, engineering, marketing, and customer service are closely coordinated, sharing real-time data to maximise efficiency, safety, and profitability.
The challenge for Sri Lankan Airlines is structural. Its operations are fragmented, overly hierarchical, and poorly aligned. Simply replacing the CEO or senior leadership will not address these deep-seated weaknesses. What the airline needs is a cohesive, integrated organisational ecosystem that leverages technology for cross-functional planning and real-time decision-making.
The government must urgently consider restructuring Sri Lankan Airlines to encourage:
=Joint planning across operational divisions
=Data-driven, evidence-based decision-making
=Continuous cross-functional consultation
=Collaborative strategic decisions on route rationalisation, fleet renewal, partnerships, and cost management, rather than exclusive top-down mandates
Sustainable reform requires systemic change. Without modernised organisational structures, stronger accountability, and aligned incentives across divisions, financial recovery will remain out of reach. An integrated, performance-oriented model offers the most realistic path to operational efficiency and long-term viability.
Reforming loss-making institutions like Sri Lankan Airlines is not merely a matter of leadership change — it is a structural overhaul essential to ensuring these entities contribute productively to the national economy rather than remain perpetual burdens.

Why Pi Day?
International Day of Mathematics falls tomorrow
The approximate value of Pi (π) is 3.14 in mathematics. Therefore, the day 14 March is celebrated as the Pi Day. In 2019, UNESCO proclaimed 14 March as the International Day of Mathematics.
Ancient Babylonians and Egyptians figured out that the circumference of a circle is slightly more than three times its diameter. But they could not come up with an exact value for this ratio although they knew that it is a constant. This constant was later named as π which is a letter in the Greek alphabet.
It was the Greek mathematician Archimedes (250 BC) who was able to find an upper bound and a lower bound for this constant. He drew a circle of diameter one unit and drew hexagons inside and outside the circle such that the sides of each hexagon touch the sides of the circle. In mathematics the circle passing through all vertices of a polygon is called a ‘circumcircle’ and the largest circle that fits inside a polygon tangent to all its sides is called an ‘incircle’. The total length of the smaller hexagon then becomes the lower bound of π and the length of the hexagon outside the circle is the upper bound. He realised that by increasing the number of sides of the polygon can make the bounds get closer to the value of Pi and increased the number of sides to 12,24,48 and 60. He argued that by increasing the number of sides will ultimately result in obtaining the original circle, thereby laying the foundation for the theory of limits. He ended up with the lower bound as 22/7 and the upper bound 223/71. He could not continue his research as his hometown Syracuse was invaded by Romans and was killed by one of the soldiers. His last words were ‘do not disturb my circles’, perhaps a reference to his continuing efforts to find the value of π to a greater accuracy.
Archimedes can be considered as the father of geometry. His contributions revolutionised geometry and his methods anticipated integral calculus. He invented the pulley and the hydraulic screw for drawing water from a well. He also discovered the law of hydrostatics. He formulated the law of levers which states that a smaller weight placed farther from a pivot can balance a much heavier weight closer to it. He famously said “Give me a lever long enough and a place to stand and I will move the earth”.
Mathematicians have found many expressions for π as a sum of infinite series that converge to its value. One such famous series is the Leibniz Series found in 1674 by the German mathematician Gottfried Leibniz, which is given below.
π = 4 ( 1 – 1/3 + 1/5 – 1/7 + 1/9 – ………….)
The Indian mathematical genius Ramanujan came up with a magnificent formula in 1910. The short form of the formula is as follows.
π = 9801/(1103 √8)
For practical applications an approximation is sufficient. Even NASA uses only the approximation 3.141592653589793 for its interplanetary navigation calculations.
It is not just an interesting and curious number. It is used for calculations in navigation, encryption, space exploration, video game development and even in medicine. As π is fundamental to spherical geometry, it is at the heart of positioning systems in GPS navigations. It also contributes significantly to cybersecurity. As it is an irrational number it is an excellent foundation for generating randomness required in encryption and securing communications. In the medical field, it helps to calculate blood flow rates and pressure differentials. In diagnostic tools such as CT scans and MRI, pi is an important component in mathematical algorithms and signal processing techniques.
This elegant, never-ending number demonstrates how mathematics transforms into practical applications that shape our world. The possibilities of what it can do are infinite as the number itself. It has become a symbol of beauty and complexity in mathematics. “It matters little who first arrives at an idea, rather what is significant is how far that idea can go.” said Sophie Germain.
Mathematics fans are intrigued by this irrational number and attempt to calculate it as far as they can. In March 2022, Emma Haruka Iwao of Japan calculated it to 100 trillion decimal places in Google Cloud. It had taken 157 days. The Guinness World Record for reciting the number from memory is held by Rajveer Meena of India for 70000 decimal places over 10 hours.
Happy Pi Day!

Sheer rise of Realpolitik making the world see the brink
The recent humanly costly torpedoing of an Iranian naval vessel in Sri Lanka’s Exclusive Economic Zone by a US submarine has raised a number of issues of great importance to international political discourse and law that call for elucidation. It is best that enlightened commentary is brought to bear in such discussions because at present misleading and uninformed speculation on questions arising from the incident are being aired by particularly jingoistic politicians of Sri Lanka’s South which could prove deleterious.
As matters stand, there seems to be no credible evidence that the Indian state was aware of the impending torpedoing of the Iranian vessel but these acerbic-tongued politicians of Sri Lanka’s South would have the local public believe that the tragedy was triggered with India’s connivance. Likewise, India is accused of ‘embroiling’ Sri Lanka in the incident on account of seemingly having prior knowledge of it and not warning Sri Lanka about the impending disaster.
It is plain that a process is once again afoot to raise anti-India hysteria in Sri Lanka. An obligation is cast on the Sri Lankan government to ensure that incendiary speculation of the above kind is defeated and India-Sri Lanka relations are prevented from being in any way harmed. Proactive measures are needed by the Sri Lankan government and well meaning quarters to ensure that public discourse in such matters have a factual and rational basis. ‘Knowledge gaps’ could prove hazardous.
Meanwhile, there could be no doubt that Sri Lanka’s sovereignty was violated by the US because the sinking of the Iranian vessel took place in Sri Lanka’s Exclusive Economic Zone. While there is no international decrying of the incident, and this is to be regretted, Sri Lanka’s helplessness and small player status would enable the US to ‘get away with it’.
Could anything be done by the international community to hold the US to account over the act of lawlessness in question? None is the answer at present. This is because in the current ‘Global Disorder’ major powers could commit the gravest international irregularities with impunity. As the threadbare cliché declares, ‘Might is Right’….. or so it seems.
Unfortunately, the UN could only merely verbally denounce any violations of International Law by the world’s foremost powers. It cannot use countervailing force against violators of the law, for example, on account of the divided nature of the UN Security Council, whose permanent members have shown incapability of seeing eye-to-eye on grave matters relating to International Law and order over the decades.
The foregoing considerations could force the conclusion on uncritical sections that Political Realism or Realpolitik has won out in the end. A basic premise of the school of thought known as Political Realism is that power or force wielded by states and international actors determine the shape, direction and substance of international relations. This school stands in marked contrast to political idealists who essentially proclaim that moral norms and values determine the nature of local and international politics.
While, British political scientist Thomas Hobbes, for instance, was a proponent of Political Realism, political idealism has its roots in the teachings of Socrates, Plato and latterly Friedrich Hegel of Germany, to name just few such notables.
On the face of it, therefore, there is no getting way from the conclusion that coercive force is the deciding factor in international politics. If this were not so, US President Donald Trump in collaboration with Israeli Rightist Premier Benjamin Natanyahu could not have wielded the ‘big stick’, so to speak, on Iran, killed its Supreme Head of State, terrorized the Iranian public and gone ‘scot-free’. That is, currently, the US’ impunity seems to be limitless.
Moreover, the evidence is that the Western bloc is reuniting in the face of Iran’s threats to stymie the flow of oil from West Asia to the rest of the world. The recent G7 summit witnessed a coming together of the foremost powers of the global North to ensure that the West does not suffer grave negative consequences from any future blocking of western oil supplies.
Meanwhile, Israel is having a ‘free run’ of the Middle East, so to speak, picking out perceived adversarial powers, such as Lebanon, and militarily neutralizing them; once again with impunity. On the other hand, Iran has been bringing under assault, with no questions asked, Gulf states that are seen as allying with the US and Israel. West Asia is facing a compounded crisis and International Law seems to be helplessly silent.
Wittingly or unwittingly, matters at the heart of International Law and peace are being obfuscated by some pro-Trump administration commentators meanwhile. For example, retired US Navy Captain Brent Sadler has cited Article 51 of the UN Charter, which provides for the right to self or collective self-defence of UN member states in the face of armed attacks, as justifying the US sinking of the Iranian vessel (See page 2 of The Island of March 10, 2026). But the Article makes it clear that such measures could be resorted to by UN members only ‘ if an armed attack occurs’ against them and under no other circumstances. But no such thing happened in the incident in question and the US acted under a sheer threat perception.
Clearly, the US has violated the Article through its action and has once again demonstrated its tendency to arbitrarily use military might. The general drift of Sadler’s thinking is that in the face of pressing national priorities, obligations of a state under International Law could be side-stepped. This is a sure recipe for international anarchy because in such a policy environment states could pursue their national interests, irrespective of their merits, disregarding in the process their obligations towards the international community.
Moreover, Article 51 repeatedly reiterates the authority of the UN Security Council and the obligation of those states that act in self-defence to report to the Council and be guided by it. Sadler, therefore, could be said to have cited the Article very selectively, whereas, right along member states’ commitments to the UNSC are stressed.
However, it is beyond doubt that international anarchy has strengthened its grip over the world. While the US set destabilizing precedents after the crumbling of the Cold War that paved the way for the current anarchic situation, Russia further aggravated these degenerative trends through its invasion of Ukraine. Stepping back from anarchy has thus emerged as the prime challenge for the world community.
