The Illusory Promise of 100,000 Years of Nuclear Waste Storage

The Swedish Enigma

In the heartlands of Sweden, a nation known for its meticulous planning, lies a colossal endeavor: the construction of an underground storage facility destined to safeguard nuclear waste for an astounding 100,000 years.

The Swedes, relying on the steadfast electricity provided by their six nuclear reactors, are embarking on a formidable task. By 2080, they aim to fill kilometers of tunnels, carved deep within ancient bedrock, with the radioactive remnants of their power generation.

A Journey Through Time

To grasp the enormity of 100,000 years, let us embark on a chronological journey back to a time when the Bronze Age was still a distant dream, some 97,000 years ago.

During this seemingly tranquil epoch, a cataclysmic event unfolded, forever altering the course of human history. The thunderous eruption of Mount Toba in Indonesia, estimated to be a hundred times more powerful than the notorious Mount Tambora eruption that caused the "Year Without a Summer" in 1816, plunged the Earth into a catastrophic ice age.

The consequences were devastating. As plant life withered, human populations dwindled perilously. Some researchers suggest that only 40 breeding pairs of humans survived, while others estimate a more generous 1,000 pairs. Even if the higher estimate held true, modern humans nearly vanished from the face of the Earth.

The Fragility of Civilization

The Mount Toba eruption serves as a chilling reminder of the fragility of human civilization. It demonstrates that over such expansive time frames, even the most advanced societies can be brought to their knees by unforeseen events.

Similarly, 40,000 years ago, our human cousins, the Neanderthals, vanished from the Earth. Once believed to be intellectually inferior to Homo sapiens, their true intelligence remains a subject of debate.

One prevailing theory suggests that climate change played a significant role in their demise. As we Homo sapiens face a similar ecological crisis today, it is plausible that human societies could descend into a state of disarray, rendering the safekeeping of nuclear waste a distant priority.

Time's Relentless Assault

Civilization as we know it is a relatively recent phenomenon, with urban settlements emerging a mere 10,000 years ago. This short lifespan hardly inspires confidence in the preservation of complex structures over the next 100,000 years.

The resilience of human society over such extended periods is uncertain. Even if the containment of nuclear waste is ensured through advanced technology, the flow of time and the uncertainties of life on Earth pose insurmountable challenges.

The Failures of the Past

Throughout history, countless civilizations have flourished and perished. Whether due to demographic decline, climate shifts, disease, or social discord, these once-mighty civilizations faded into oblivion.

This sobering reality begs the question: how can we, as a species known for our recklessness and short-sightedness, possibly assume the responsibility of safeguarding nuclear waste for 100,000 years?

The Role of Reprocessing

While nuclear waste disposal poses significant challenges, reprocessing offers a potential solution. By extracting usable radioactive elements from waste, its volume can be reduced, albeit not eliminated.

However, reprocessing is a costly and inherently risky endeavor that doubles down on our reliance on advanced technology. It also raises concerns about nuclear weapons proliferation, given that plutonium extracted during reprocessing can be utilized in their production.

The Inadequacy of Current Solutions

Despite mounting concerns, nuclear waste production continues to escalate worldwide. The construction of new nuclear reactors proceeds unabated, yet no viable solution has emerged to address the disposal of waste on a global scale.

In comparison to reprocessing or the far-fetched ideas of launching waste into space or the Sun, burying waste underground seems like a cheap and pragmatic alternative.

Preserving Knowledge for Posterity

Even if we assume that the nuclear waste storage facility in Sweden will withstand the passage of time, the preservation of knowledge regarding its existence presents a formidable challenge.

Given our species' propensity for destruction and disregard for long-term consequences, it is doubtful that we can construct anything that will endure for 100,000 years.

The Hubris of Creating Long-Lived Hazards

Fundamental questions arise: Was it prudent to create something that requires such meticulous care over such an extended period? Are we responsible enough to assume the burden of safeguarding this hazardous legacy for generations to come, considering how reckless we have been as a species?

The presence of nuclear waste, with its inherent dangers, hangs like a specter over our current civilization, posing a potential threat far beyond our own lifetimes. The echoes of time may ultimately curse us for our recklessness and the folly of believing we could control the unpredictable dance of history.
