Nuclear power is a critical element in limiting greenhouse gas emissions, and a new Technology Roadmap co-authored by the International Energy Agency (IEA) and the Nuclear Energy Agency outlines the next steps for growth in the aftermath of the Fukushima Daiichi accident in Japan and the economic crisis and its effect on financing.
Nuclear prospects remain positive
The new publication finds that the prospects for nuclear energy remain positive in the medium to long term despite a negative impact in some countries in the aftermath of the accident. While nuclear power’s share of global electricity generation was 10% lower in 2013 than in 2010, principally because of Japan’s 48 operable reactors remaining idle, it is still the second-largest source worldwide of low-carbon electricity. And the 72 reactors under construction at the start of last year were the most in 25 years. Yet global capacity must more than double, with nuclear supplying 17% of global electricity generation in 2050, to meet the IEA 2 Degree Scenario (2DS) for the most effective and efficient means of limiting global temperature rise to the internationally agreed maximum.
Technology Roadmap: Nuclear Energy 2015 Update
Technology Roadmap: Nuclear Energy 2015 Update offers a vision of the best ways to accomplish that growth, looking at current and new technologies; the need to meet increased safety requirements and improve constructability through optimised design, standardisation and more efficient supply chains; financing options and implementation of waste-management solutions. The Roadmap also addresses the challenge of decommissioning hundreds of reactors that will reach the end of their operating life by the middle of the century as well as building the necessary infrastructure and capacity building in newcomer countries. Nuclear energy’s attractiveness lies in how it allows countries to build scalable, efficient and long-term power sources that can serve as a base to underpin other forms of low-carbon generation. Even if a limited number of countries have decided to phase out nuclear power, many more have set ambitious development programmes.
