The International Atomic Energy Agency (IAEA) works to apply nuclear technology in four of the seven areas identified as priorities for the UN conference on Sustainable Development or Rio+20: energy, food, water and oceans.

Nuclear technologies are used daily to find and protect sustainable sources of fresh water, produce energy and food, while providing researchers the tools to study the ocean's past and predict its future.

Access to affordable energy is essential for attaining any development goals.

If countries choose to pursue nuclear power, the IAEA helps them to do so safely, securely, economically and sustainably.

Louise Potterton spoke to the IAEA's Hans Holger Rogner, Section Head of the Planning and Economic Section within the Department of Nuclear Energy.
