In Germany, suitable long-term storage sites for nuclear waste are still being sought. They must be built in deep geological layers in order to create permanent security. But how do you prevent future generations from inadvertently entering these places? Simply because they don’t know that such dangerous substances are stored there? Solutions must be found now, says Wolfram König, President of the Federal Office for Safety in Nuclear Waste Management.
According to König, knowledge must be preserved through accurate documentation of where something is, through symbols and buildings. “We need to create security in a way that you can forget about it,” he says. But what language, what signs will people understand in the distant future? It’s very complex.
Classic information carriers are perfectly suitable: in addition to paper, ceramic is also possible, according to König, because it “ensures long-term documentation”. And it’s proven to “carve something in stone.” This is to attract attention when people stand in front of a locked entrance.
Regarding nuclear technology, König points out: “These are enormous potential risks.” And the “incredibly long”.
