[en] The timescales over which the hazard exists from radioactive waste (as well as from other wastes) are much longer than just a few thousands of years, and it must be accepted that the current generation's capacity to ensure continued integrity of the disposal facility cannot be projected indefinitely into the future, but rather diminishes with time. At the same time there is a common understanding that we should not 'walk away' from these facilities or conceal them, even when we think they will be safe. In fact, the sense of safety will come from continuing, over time, some element of familiarity and control - hence the need to conceptualise a 'rolling future' in which each generation takes responsibility to ensure continuity and safety for the succeeding several generations, including a need for flexibility and adaptability to circumstances as they change. The issue of archives and markers that last as long as possible (the technological approach) continues to be a topical one. However, physical markers and archives may be complemented by - or integrated within - a cultural tradition that could be sustained over time starting with the planning of a repository and continuing through its implementation and beyond its closure. The mandated need to install 'permanent' records and markers can only be fulfilled if one acknowledges that these will evolve over time. Namely, they will become part of the local, subsequent cultures, and they will (or ideally should) be renewed as their materials are degraded, or as their significance evolves. Because a radioactive waste management repository and site will be a permanent presence in a host community for a very long time, a fruitful, positive relationship must be established with those residing there, now and in the future. Simply put, designers have to make the radioactive waste management facility and site to suit people's present needs, ambitions and likings, and to provide for evolution to match at reasonable cost the needs and desires of future generations. The challenge is to design and implement a facility (with its surroundings) that is not only accepted, but in fact becomes a part of the fabric of local life and even something of which the community can be proud. Parts of the facility and its surroundings may thus become themselves welcome markers of the existence of a waste repository underground
