<p>Twenty-five years ago, the explosion at Chernobyl cast a radioactive cloud over Europe and a shadow around the world. Today, the tragedy at Japan’s Fukushima Daiichi nuclear power plant continues to unfold, raising popular fears and difficult questions.<br /><br />Visiting Chernobyl a few days ago, I saw the reactor, still deadly but encased in concrete. The adjoining town of Pripyat was dead and silent — houses empty and falling into ruin, mute evidence of lives left behind, an entire world abandoned and lost to those who loved it.<br /><br />More than 3,00,000 people were displaced in the Chernobyl disaster; roughly six million were affected. A swathe of geography half the size of Italy or my own country, the Republic of Korea, was contaminated.<br /><br />It is one thing to read about Chernobyl from afar. It is another to see for it. For me, the experience was profoundly moving, and the images will stay with me for many years. I was reminded of a Ukrainian proverb: “There is no such thing as someone else’s sorrow.” The same is true of nuclear disasters. There is no such thing as some other country’s catastrophe.<br /><br />No borders<br /><br />As we are painfully learning once again, nuclear accidents respect no borders. They pose a direct threat to human health and the environment. They cause economic disruptions affecting everything from agricultural production to trade and global services.<br /><br />This is a moment for deep reflection, a time for a real global debate. To many, nuclear energy looks to be a clean and logical choice in an era of increasing resource scarcity. Yet the record requires us to ask: have we correctly calculated its risks and costs? Are we doing all we can to keep the world’s people safe?<br /><br />Because the consequences are catastrophic, safety must be paramount. Because the impact is transnational, these issues must be debated globally.<br /><br />That is why, visiting Ukraine for the 25th anniversary of the disaster, I put forward a five-point strategy to improve nuclear safety for our future:<br /><br />First, it is time for a top to bottom review of current safety standards, both at the national and international levels.<br /><br />Second, we need to strengthen the work of the International Atomic Energy Agency on nuclear safety.<br /><br />Third, we must put a sharper focus on the new nexus between natural disasters and nuclear safety. Climate change means more incidents of freak and increasingly severe weather. With the number of nuclear facilities set to increase substantially over the coming decades, our vulnerability will grow.<br /><br />Fourth, we must undertake a new cost-benefit analysis of nuclear energy, factoring in the costs of disaster preparedness and prevention as well as cleanup when things go wrong.<br />Fifth and finally, we need to build a stronger connection between nuclear safety and nuclear security. At a time when terrorists seek nuclear materials, we can say with confidence that a nuclear plant that is safer for its community is also more secure for the world.<br /><br />My visit to Chernobyl was not the first time I have traveled to a nuclear site. A year ago, I went to Semipalatinsk in Kazakhstan, ground zero for nuclear testing in the former Soviet Union. Last summer in Japan, I met with the Hibakusha, survivors of the atomic blasts at Nagasaki and Hiroshima.<br /><br />I went to these places to highlight the importance of disarmament. For decades, negotiators have sought agreement on limiting (and perhaps ultimately eliminating) nuclear weapons. And this past year, we have seen very encouraging progress.<br /><br />With the memory of Chernobyl and, now, the disaster in Fukushima, we must widen our lens. Henceforth, we must treat the issue of nuclear safety as seriously as we do nuclear weapons.<br /><br />The world has witnessed an unnerving history of near-accidents. It is time to face facts squarely. We owe it to our citizens to practice the highest standards of emergency preparedness and response, from the design of new facilities through construction and operation to their eventual decommissioning.<br /><br />Let us resolve to dispel the last cloud of Chernobyl and offer a better future for people who have lived for too long under its shadow.<br /><br /><em>(The writer is the secretary general of the United Nations)</em><br /> IHT</p>
