Five Years after the Fukushima Daiichi Accident: Nuclear Safety Improvements and Lessons Learnt

Countries around the world continue to implement safety improvements and corrective actions based on lessons learnt from the 11 March 2011 accident at the Fukushima Daiichi nuclear power plant. This report provides a high-level summary and update on these activities, and outlines further lessons learnt and challenges identified for future consideration. It focuses on actions taken by NEA committees and NEA member countries, and as such is complementary to reports produced by other international organisations.

The Safety Culture of an Effective Nuclear Regulatory Body

The fundamental objective of all nuclear safety regulatory bodies is to ensure that activities related to the peaceful use of nuclear energy are carried out in a safe manner within their respective countries. In order to effectively achieve this objective, the nuclear regulatory body requires specific characteristics, one of which is a healthy safety culture. This regulatory guidance report describes five principles that support the safety culture of an effective nuclear regulatory body. These principles concern leadership for safety, individual responsibility and accountability, co-operation and open communication, a holistic approach, and continuous improvement, learning and self-assessment.

Implementation of Defence in Depth at Nuclear Power Plants

Defence in depth (DiD) is a concept that has been used for many years alongside tools to optimise nuclear safety in reactor design, assessment and regulation. The 2011 Fukushima Daiichi nuclear power plant accident provided unique insight into nuclear safety issues and raised questions about the tools used at nuclear power plants, including the effectiveness of the DiD concept, and whether DiD can be enhanced and its implementation improved. This report is intended primarily for nuclear regulatory bodies, although information included herein is expected to be of interest to licensees, nuclear industry organisations and the general public.

Nuclear Energy: Combating Climate Change

The global response to address climate change is a key policy challenge of the 21st century. Many governments around the world have agreed that action should be taken to achieve large cuts in greenhouse gas (GHG) emissions over the coming decades, to adapt to the impacts of climate change and to ensure the necessary financial and technical support for developing countries to take action.

Nuclear Energy Data – 2015

Nuclear Energy Data is the OECD Nuclear Energy Agency's annual compilation of statistics and country reports documenting nuclear power status in the OECD area. Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projected generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants increased slightly in 2014, by 1.4% and 0.3% respectively, despite Japan's nuclear fleet remaining offline throughout the year.

Projected Costs of Generating Electricity – 2015 Edition

This joint report by the International Energy Agency (IEA) and the Nuclear Energy Agency (NEA) is the eighth in a series of studies on electricity generating costs. As policy makers work to ensure that the power supply is reliable, secure and affordable, while making it increasingly clean and sustainable in the context of the debate on climate change, it is becoming more crucial that they understand what determines the relative cost of electricity generation using fossil fuel, nuclear or renewable sources of energy. A wide range of fuels and technologies are presented in the report, including natural gas, coal, nuclear, hydro, solar, onshore and offshore wind, biomass and biogas, geothermal, and combined heat and power, drawing on a database from surveys of investment and operating costs that include a larger number of countries than previous editions.
