Support new construction: Ensure that licensing processes do not lead to project delays and cost increases that are not justified by safety requirements.

Create a favourable financing framework: Create risk management and financing frameworks that facilitate the mobilisation of capital for new and existing plants at an acceptable cost taking the risk profile and long time-horizons of nuclear projects into consideration.

Where technically possible, this should include allowing flexible operation of nuclear power plants to supply ancillary services.

Update safety regulations: Where necessary, update safety regulations in order to ensure the continued safe operation of nuclear plants.

Value non-market benefits: Establish a level playing field for nuclear power with other low-carbon energy sources in recognition of its environmental and energy security benefits and remunerate it accordingly.

Make sure that the providers of these services, including nuclear power plants, are compensated in a competitive and non-discriminatory manner.

Value dispatchability: Design the electricity market in a way that properly values the system services needed to maintain electricity security, including capacity availability and frequency control services.

Keep the option open: Authorise lifetime extensions of existing nuclear plants for as long as safely possible.

In this context, countries that intend to retain the option of nuclear power should consider the following actions: As such, the feasibility of extensions depends largely on domestic market conditions. An extended period of low wholesale electricity prices in most advanced economies has sharply reduced or eliminated margins for many technologies, putting nuclear at risk of shutting down early if additional investments are needed. However difficult market conditions are a barrier to lifetime extension investments. The estimated cost of extending the operational life of 1 GW of nuclear capacity for at least 10 years ranges from $500 million to just over $1 billion depending on the condition of the site. Nevertheless they still represent a substantial capital investment. It is considerably cheaper to extend the life of a reactor than build a new plant, and costs of extensions are competitive with other clean energy options, including new solar PV and wind projects. Given their age, plants are beginning to close, with 25% of existing nuclear capacity in advanced economies expected to be shut down by 2025. However the nuclear fleet in advanced economies is 35 years old on average and many plants are nearing the end of their designed lifetimes. In emerging and developing economies, particularly China, the nuclear fleet will provide low-carbon electricity for decades to come. In the absense of further lifetime extensions and new projects could result in an additional 4 billion tonnes of CO2 emissions, underlining the importance of the nuclear fleet to low-carbon energy transitions around the globe.

It recommends several possible government actions that aim to ensure existing nuclear power plants can operate as long as they are safe, support new nuclear construction and encourage new nuclear technologies to be developed. This report identifies the even greater challenges of attempting to follow this path with much less nuclear power. It requires large increases in efficiency and renewables investment, as well as an increase in nuclear power. Achieving the pace of CO2 emissions reductions in line with the Paris Agreement is already a huge challenge, as shown in the Sustainable Development Scenario. It is shown that, without action, nuclear power in advanced economies could fall by two thirds by 2040.The implications of such a “nuclear fade case” for costs, emissions and electricity security using two World Energy Outlook scenarios are examined in the New Policies Scenario and the Sustainable Development Scenario. This report focuses on the role of nuclear power in advanced economies and the factors that put nuclear power at risk of future decline. However, in advanced economies, nuclear power has begun to fade, with plants closing and little new investment made, just when the world requires more low-carbon electricity. Over the past 50 years, the use of nuclear power has reduced CO2 emissions by over 60 gigatonnes – nearly two years’ worth of global energy-related emissions.

Together, they provide three-quarters of global low-carbon generation. Nuclear power and hydropower form the backbone of low-carbon electricity generation.
