@ErikUden Es gibt doch keine Endlager???? Egal, frag mal nach Nachhaltigkeit bei Software, Dateiformaten und Dokumentenstandards. Wie stellen die sicher, dass relevante Doku auch in 10, 20, 30 Jahren / Jahrzehnten / Generationen noch lesbar sind?

@ErikUden der Müll wievieler AKWs mit wie viel Laufzeit passt in ein Lager. Wieviele Endlager bräuchte es, wenn wir auf die Kernkraft Apologeten gehört hätten und diesen Quatsch nicht nur dran gegeben hätten sondern auch noch ausgeweitet?

Da dies für Verwirrung gesorgt hat: Ich spreche vom Endlager Konrad in Salzgitter. Ist es ein echtes Endlager? Vielleicht sollte Ich mit der Frage anfangen...

@ben Scheint so:

Endlager Konrad – Wikipedia

(de.wikipedia.org)

Oder viel mehr, es wird dazu gebaut...?!

@Wolf Sehr gute Frage.

@solarplexus Leider ist es der Schacht Konrad! Du scheinst dich aber auszukennen :]

@moreentropy Leider nicht Asse, sondern Konrad!

@Oeltanks ehm... ja?! Was denn?

@majortom Sehr gute Frage!

@nahtanoy wichtigste Frage!

@mfeilner Guter Punkt! Ich werde beim „Endlager” Konrad sein.

@Euchrid wichtige Frage!

Heute ist der Tag meines Besuchs des Atommüll Endlagers Konrad in Salzgitter. Der Schacht geht 1200m tief, und der Bereich den wir betreten wird über 35°C warm.

Jeder von uns bekommt eine Sauerstoffflasche für den Fall das wir verschüttet werden, da die Bergungsarbeiten ein paar Wochen dauern würde.

Wünscht mir Glück.

Glück auf! Ich bin heil wieder zurückgekommen, aber nicht als gleicher Mensch. Ich hoffe heute Nacht noch berichten zu können.

@ErikUden Nach einem unbemerktem Unfall im Atommüll Endlager kam Erik Uden verändert zurück. Er wusste nicht, dass er jetzt Katzenfresser Uden ist.

@VeeLux ich habe sie lediglich etwas zu sehr geküsst

A short while ago I was allowed to visit a long term nuclear waste storage facility, built to hold low and mid tier radioactive material for geological time (hundreds of thousands to a few million years).

I entered early in the morning and got into an elevator driving me 800 meters deep, with the complex tunnel system we toured going up to a kilometer down from the surface. I came up in the late afternoon a changed man due to what I've seen.

@ErikUden why dose low level ways need long term storage?
I thought that stuff was safe within weeks or months. Honestly I though med level only need a few decades of storage

@spycrab there's no internationally (even European) agreed upon standard for classifying nuclear waste. Low- to mid-range in this context could mean something entirely different.

After multiple hours underground, having already met dozens of workers, who spend their days at a job without any sunlight in a grotesque world I could've never imagined, we finally arrived at the actual site where nuclear waste will be stored for millenia. I've seen the many tunnels stretching multiple kilometers in one direction in which the actual barrels and other containers for nuclear material will be put, completely drowned in cement, segment by segment, and then closed off for a time longer than the human species has existed, starting the load up in 2030 until 2070 in the city of Salzgitter, in my state of Lower-Saxony.

This facility will only be able to store half of Germany's low- and mid-tier nuclear waste, only a bit over 300.000m³ of it. While this type of waste makes up for ~95% of all nuclear waste in Germany, it's still less than a percent of total radiation emitted by all nuclear material. The other 99% is emitted by the high-tier nuclear waste, which there currently isn't any solution for storing on planet earth, yet. Don't get confused by the classiciations like “low”, “mid”, and “high”, as there is no international (or even European) standard for classifying nuclear waste. I was told by the leader of the BGE, Germany's federal company for radioactive waste disposal, that there was an attempt to create such a standard at a working group of the IAEA (International Atomic Energy Agency), which she was a part of, but they gave up after just four weeks.

This facility was so deep underground as a rather arbitrary choice, simply because that's how deep the iron miners went when this was an actual mine. The storage facility in France (Le Monge) is only 500 meters deep, in some European countries even less. The advantage of this here is that no ice age or glacier period has ever affected the underground this low (permafrost or thermal penetration doesn't go deeper than 500m). Still, by today's standards for nuclear long term waste storage, a facility like this wouldn't be chosen, not just due to nearby underground water streams potentially breaking in and leaking nuclear waste into one of the largest rivers of Europe, but also because the city formed around the iron mine, and the 40 years of loading nuclear waste down this facility will come with accidents and an increased radiation to the people living here.

The room, if you could call it that, rather the tunnel, the complex where nuclear waste would be stored, was hot. Like Icarus who flew too close to the sun, I wasn't aware that just a kilometer below the earth's crust, we'd reach sweating temperatures of 37°C to even 40°C due to the earth's core emitting its heat.

While the goal of this presentation was for Germany's federal company for radioactive waste disposal (BGE) to convince us that this facility was safe so we'd endorse it in state and federal parliament, maybe even for them to polish their image, there were certain topics they omitted talking about. My favorite topic was one of them: Long-term nuclear waste warning messages.

We were told about how perfect this facility was, how nothing could penetrate it, and in geological time, all the simulations possibly proving otherwise, were misleading, so I asked about the one thing they forgot mentioning: the human element. Just 5000 years ago they built the pyramids, now archeologists rediscover and search through them. With billions going into this facility, won't people finding any record of this place possibly believe humanity's most valuable items to be stored here? Shouldn't we install long-term warning messages for future generations? I asked.

The leader of the facility responded “We cannot take responsibility for future civilizations.”

Standing in the chambers that are built to exist for over two million years, those words sent a shiver down my spine. I realized that this would be our generation's legacy: debt and a broken planet.
