Projected Costs of Generating Electricity, 2015 editionProjected Costs of Generating Electricity, 2015 edition

This joint report by the NEA and the International Energy Agency (IEA) is the eighth in a series of studies on electricity generating costs. The analysis of more than 180 plants, based on data from 22 countries, reveals several key trends, pointing, for example, to a significant decline in recent years in the cost of renewable generation. The report also reveals that nuclear energy costs remain in line with the cost of other baseload technologies, particularly in markets that value decarbonisation. Overall, cost drivers of the different generating technologies remain both market‑specific and technology‑specific. Find out more and download the executive summary:

Radioactive waste management

International Workshop on Challenges to the Regulators in Siting and Licensing the Construction and Operation of Radioactive Waste Repositories, Helsinki, FinlandChallenges to regulators in siting and licensing the construction and operation of radioactive waste repositories

On 8‑9 September 2015, the NEA Regulators' Forum held an international workshop on Challenges to the Regulators in Siting and Licensing the Construction and Operation of Radioactive Waste Repositories. The workshop was hosted by the Finnish Ministry of Employment and the Economy (MEE) and the Radiation and Nuclear Safety Authority (STUK) in Helsinki, Finland. It provided a forum to discuss and to exchange experience and approaches in preparing for license application reviews. It also delivered an overview of the current status of waste management programmes in developing geological repositories in eleven NEA member countries. Participants highlighted the necessity to establish an early regulator-implementer dialogue, an independent regulator, a regulatory framework which includes requirements and guidelines, stakeholder engagement, and international benchmarking and co‑operation.
