• Today’s nuclear energy

plants are a very competitive source of long-term electricity supply

• Costs of renewables are

dropping, but without subsidies are still high

• Costs of natural gas still

set the pace for the market and are generally low Levelised Cost for Plants Built in 2020

It depends…

A price that reflects the true value

Accounting for full costs informs public debate but cannot substitute for it. Social and political discussions will give different weights to different variables in different countries

Plant-level production costs at market prices Grid-level costs of the electricity system Full costs including social costs of emissions, land-use, climate change, security of supply, etc.

The more you build nuclear power plants the better you get at it: practice does make perfect in the nuclear business

NEA: Helping governments

All NEA publications available at www.oecd-nea.org

The NEA: A framework to address global challenges

The role of the NEA is to:

• Foster international co-operation

to develop the scientific, technological and legal bases required for a safe, environmentally friendly and economical use of nuclear energy for peaceful purposes.

• Develop authoritative

assessments and forge common understandings on key issues as input to government decisions on nuclear technology policy.

• Conduct multinational research

into challenging scientific and technological issues.

NEA countries operate nearly 90%

• f the world's installed nuclear capacity
