[en] NEA member countries are currently developing deep geological disposal projects for radioactive waste and spent fuel. These facilities will be implemented and operated over several decades. Once closed, they are to remain safe for millennia. Geological repositories are designed to be intrinsically safe and final; safety is not to depend on human presence and intervention. However, there is no intention to forgo, at any time, records, knowledge, memory (RK and M) and awareness of the repository and the waste it contains. Besides, specific requirements may have to be fulfilled in the area of RK and M based on national legislation and regulation, e.g. in the area of preventing human intrusion, favouring retrievability of the waste, or to simply allow future generations to make their own informed decisions about the waste. Additionally, host communities and regions have indicated a strong interest in that appropriate provisions exist for preserving detailed information about the repository for as long as possible. As a result, national programmes are actively seeking to improve their understanding of the preservation of RK and M about radioactive waste across generations and to implement the necessary provisions. The NEA Radioactive Waste Management Committee (RWMC) initiative on the Preservation of RK and M across Generations was launched to meet the demands from member countries for facilitating exchange and fostering reflection in this area, including formulating common approaches. This initiative has as its focus the period of time after repository closure; another initiative, RepMet, deals with the period before closure. There is no single mechanism or technique that, by itself, would achieve the preservation of RK and M over centuries and millennia. Rather, an integrated set of mechanisms and techniques - technical, administrative and societal - is needed to address the various timescales and to support one another. The RK and M initiative started in 2011 with the first phase ending in March 2014, at which time the RWMC decided to extend the initiative until 2017. 19 organisations from 13 countries, representing policy makers, regulators, implementing agencies and R and D institutions, participate in the initiative in this second phase. Complementing the long-term, post-closure focus of the RK and M initiative, an initiative concentrating on the pre-closure period and the management of (meta-)data about radioactive waste and geological repositories was launched jointly with the Integration Group for the Safety Case (IGSC). The new, Radioactive Waste Repository Metadata Management (RepMet) initiative aims to bring about a better understanding of the identification and administration of metadata to support national programmes in managing their radioactive waste repository data, information and records in a way that is both harmonised internationally and suitable for long-term management and use. The first meeting of the RepMet initiative took place on 20-21 January 2014 at the NEA. The NEA RWMC adopted a collective statement on 'Foundations and guiding principles for the preservation of records, knowledge and memory across generations: A focus on the post-closure phase of geological repositories' at its 47. session, which took place on 27-28 March 2014 at the OECD conference centre. A number of project studies were published in 2013/14 and are available on the RK and M web site. Several RK and M group meetings took place at NEA, Paris, in April and September 2013, and February, April, and May 2014. 'Constructing Memory', an international conference and debate on the preservation of records, knowledge and memory of radioactive waste across generations, will take place in Verdun (France) in September 2014. This progress report is the third of the RK and M initiative and covers the March 2013 - March 2014 period
