IGNACE, Ontario, C.E. 51,500—Feloo, a hunter, chews a strip of roasted caribou flank, washing it down with water from a close-by lake. Her boots press into skinny soil that, every summer season, thaws right into a sodden marsh above frozen floor. Caribou herds drift throughout the tundra, nibbling lichen and calving on the open flats. Hooves sink into moss beds; antlers scrape dwarf shrubs. Overhead, migratory birds wheel and squawk earlier than winging south. Two lakes stay liquid year-round, held open by hidden taliks—oases of water in a frozen land. Beneath all of it lies the Canadian Defend: a billion-year-old granite craton, a basement of rock, scarred by ice, that has endured glaciation after glaciation. In 10 or 15 millennia, Feloo’s world will vanish beneath three kilometers of advancing ice.
Feloo is unaware that 500 meters under her toes rests an ancestral deposit of copper, metal, clay and radioactive particles. Way back, this land was referred to as Canada. Right here a bunch generally known as the Nuclear Waste Administration Group (NWMO) constructed a deep geological repository to comprise spent nuclear gas—the byproducts of reactors that when powered Ontario, Quebec and New Brunswick. The vault was engineered to isolate long-lived radionuclides akin to uranium 235, which has a half-life that exceeds 700 million years—sealing them away from struggle, catastrophe, neglect, sabotage and curiosity for so long as human foresight might attain.

NWMO issued reviews with titles akin to Postclosure Security Evaluation of a Used Gas Repository in Crystalline Rock. These research modeled future boreal forests and tundra ecosystems, simulating the waxing and waning of huge glacial ice sheets throughout successive ice ages. They envisioned the lifeways of self-sufficient hunters, fishers and farmers who may sooner or later inhabit the area—and even the distant risk of a far-future drill crew inadvertently breaching the buried canisters.
Feloo was born right into a world that has remembered none of this. Information of the repository had been misplaced within the world drone wars of C.E. 2323. All that endured had been the tales of Mishipeshu, the horned water panther stated to dwell beneath the lakes—and to punish those that dig too deep. A few of Feloo’s companions dismiss the legend; others whisper that the earth under nonetheless burns with poison. But each step she takes is haunted by decisions made tens of millennia earlier than—when Canada undertook the Promethean activity of safeguarding a future it might scarcely think about.
In 2024 NWMO introduced that Canada’s deep geological repository for spent nuclear gas could be constructed within the granite formations of northwestern Ontario, close to the Township of Ignace and the Wabigoon Lake Ojibway Nation. The choice capped off a 14-year siting effort that solicited volunteer host communities and assured them the appropriate to withdraw at any stage of the method. NWMO is now making ready for a complete regulatory evaluation, which is able to embody a licensing course of performed by the Canadian Nuclear Security Fee. This implies the event of affect assessments that will probably be particular to the Ignace web site. NWMO has additionally pledged an Indigenous-led regulatory course of alongside federal oversight, with the Wabigoon Lake Ojibway Nation conducting its personal assessments to make sure the mission displays Anishinaabe ideas of ecological stewardship. If approvals proceed, building might start within the 2030s, and the repository might go into operation within the 2040s.
A deep-time repository, like a deep-space probe, should endure with out upkeep or intervention, independently carrying human intent into the far future.
A deep geological repository may be seen as a reverse ark: a vessel designed to not carry valuables ahead in time however to seal harmful legacies away from historic reminiscence. Or it may be understood as a reverse mine: an effort returning hazardous remnants to the Earth reasonably than extracting assets from it. Both method it’s greater than only a feat of engineering. Repository tasks weave collectively scientific reasoning, intergenerational ethics and group preferences in choices that are supposed to endure longer than empires. As messages to future variations of ourselves, they compel their designers to ask: What symbols, tales or establishments may bridge epochs? And what does it imply that we try to guard future people who might exist solely in our imaginations?
I’m a cultural anthropologist. From 2012 to 2014 I spent 32 months residing in Finland, conducting fieldwork among the many security evaluation groups for Onkalo—an underground complicated that’s prone to grow to be the world’s first operational deep geological repository for spent nuclear gas. The groups’ work concerned modeling far-future glaciations, earthquakes, floods, erosion, permafrost and even hypothetical human and animal populations tens of millennia forward. That analysis grew to become the idea for Deep Time Reckoning, a ebook exploring how nuclear-waste consultants’ long-range planning practices may be retooled as blueprints for safeguarding future worlds in different domains, from local weather adaptation to biodiversity preservation.
In the course of the Biden administration, I joined the U.S. Division of Vitality’s Workplace of Spent Gas and Excessive-Stage Waste Disposition, the place I helped advance participatory siting processes modeled on approaches that had confirmed profitable in Finland and Canada. I served as federal supervisor of the DOE’s Consent-Primarily based Siting Consortia—a nationwide coalition of 12 mission groups from universities, nonprofits and the personal sector that had been tasked with fostering group engagement with nuclear waste administration. Via all of it, I got here to see repository packages as civilizational experiments in long-term duty: collective efforts to increase the time horizons of governance and care in order that shared futures could also be protected far past the dimensions of any single lifetime or establishment.
A permanent query for all repository packages is whether or not—and, in that case, how—to mark their websites and archive information about them. There isn’t a assure that the languages we converse at present will stay intelligible even a number of thousand years from now. Beowulf, written in an earlier type of English a millennium or so in the past, already reads like a overseas tongue. The meanings of symbols drift simply as unpredictably. A cranium and crossbones, as an illustration, might denote poison, loss of life, rebirth—or pirates—relying on tradition and context. What, then, may a nuclear waste repository signify to individuals tens of millennia from now? How lengthy can a warning signal, monument, or archive protect the meanings we connect to it at present? Or ought to we abandon the phantasm of speaking with future people like Feloo altogether—and as a substitute construct repositories that are supposed to be forgotten?
Nuclear organizations depend on acquainted methods to protect institutional reminiscence: documentation mandates, digital databases, mentoring pipelines, program redundancy, succession planning. Such mechanisms can maintain continuity for many years, even centuries—however their limits grow to be clear when stretched throughout millennia. Archives can burn. Applied sciences can decay into obsolescence. Establishments can falter underneath political or financial upheaval. And at present a brand new litany of planetary dangers crowds the horizon: thermonuclear struggle, weaponized artificial biology, climate-driven migrations, institutional collapse, even runaway synthetic superintelligence.
As NWMO prepares for building in Ignace within the 2030s, the query of long-term communication should more and more shift from concept to observe. Canada has participated within the Group for Financial Co-operation and Improvement’s Nuclear Vitality Company’s Preservation of Information, Data and Reminiscence initiative, which has explored methods starting from warning markers to staged transfers of duty throughout generations. In a 2017 security report, NWMO properly conceded a restrict: “repository information and markers (and passive societal reminiscence) are assumed ample to make sure that inadvertent intrusion wouldn’t happen for at the least 300 … years.” Past that horizon, the premise modifications. No monument, land-use restriction, monitoring system or archive may be trusted to endure indefinitely.
Totally different international locations have embraced completely different philosophies of easy methods to safeguard nuclear waste repositories throughout centuries and millennia—and the way and whether or not to attempt to ship messages to those that, like Feloo, might sooner or later stay above them.
The U.S. is residence to the Waste Isolation Pilot Plant (WIPP), a deep geological repository carved into historic salt beds in New Mexico. WIPP shops transuranic waste from the nation’s nuclear weapons packages. Within the Nineteen Eighties and Nineteen Nineties, activity forces convened scientists, artists, science-fiction writers and semioticians to design warning methods that had been meant to discourage drill crews or archaeologists residing 1000’s of years sooner or later. Their proposals had been dramatic: huge fields of concrete thorns bristling from the desert ground; monolithic slabs etched with multilingual warnings (“this place is just not a spot of honor … nothing valued is right here”); and signage depicting the anguished face of Edvard Munch’s The Scream. Some envisioned a quasi-religious “atomic priesthood” to protect the warning via ritual. Others steered bioengineered “ray cats” whose fur would fluoresce close to radiation—accompanied by myths, songs and proverbs to make sure that unborn generations would know to flee.
Finland’s Onkalo repository embodies a considerably completely different a philosophy. Anticipating the long run lack of institutional management and reminiscence of the repository, Onkalo was designed to stay safe for millennia within the absence of monumental communication methods. As in Canada, the dearth of exploitable assets within the granite bedrock is supposed to discourage future prospectors. As soon as its tunnels are filled with copper canisters and bentonite clay, Onkalo will probably be backfilled and sealed for perpetuity on a small, unassuming islet within the Baltic Sea someday within the 2120s. The hazard is to be buried so utterly that there will probably be nothing left to recollect: no attention-grabbing monoliths to tempt curiosity, no symbols to be misinterpret. Once I performed anthropological fieldwork in Finland, some scientists likened the mission to launching a probe into interstellar house: years of meticulous planning and testing culminating in a single, irrevocable launch. After that, no restore or recall is feasible. A deep-time repository, like a deep-space probe, should endure with out upkeep or intervention, independently carrying human intent into the far future.
Even the mightiest empires have cycled via collapse and renewal, via forgetting and rediscovery.
France has charted a 3rd path with its Cigéo repository, deliberate within the Callovo-Oxfordian clay of its northeastern departments of Meuse and Haute-Marne. A 2016 regulation requires Cigéo to stay reversible for at the least a century after operations start. In observe, reversibility means retrievability: the inbuilt capability to get well waste packages from the underground deposition cells. Advocates see this as a steadiness between long-term containment and intergenerational company: the concept that future residents ought to retain the appropriate to revisit, and even overturn, decisions made at present. This logic resonates with those that view spent nuclear gas as a future useful resource greater than a legal responsibility. Jenifer Schafer, an affiliate director for know-how on the DOE’s Superior Analysis Initiatives Company–Vitality, has argued that “nuclear treasure” could also be a extra becoming time period than “nuclear waste,” because the fissile supplies inside it might sometime energy future improvements in nuclear reactor design. From this angle, burying spent nuclear gas too conclusively dangers foreclosing prospects that future generations may favor to maintain open.
Taken collectively, these examples reveal how in another way societies think about their obligations to the far future. The American technique mirrored a lingering cold-war-era religion—tinged with hubris—in design ingenuity to frighten descendants away. The Finnish plan entrusted geology with the work of erasure, even when people’ reminiscence had been to lapse because the panorama quietly reclaimed the positioning. The French framework preserved the appropriate of future residents to reject the choices of at present. Canada nonetheless has regulatory milestones and First Nations approvals to satisfy earlier than NWMO can break floor at Ignace. Within the many years forward, nevertheless, it, too, should specify the way it will stage its strategy to intergenerational communication.
What is definite, although, is that NWMO’s deep geological disposal efforts will unfold not solely as a technical mission but additionally as a cultural assertion—a press release about care throughout generations, the boundaries of understanding throughout distinction and the ethical duties of present-day Canadians to these not but born. Like all repository efforts, NWMO’s work in Ignace will function a mirror: a message not solely to the long run but additionally to the current, reflecting what we select to recollect, what we select to neglect and the way we hope to be remembered ourselves.
As NWMO refines its strategy to remembering, forgetting and speaking with societies of the long run, it could do properly to look past the nuclear business for inspiration.
Japan’s Kongō Gumi building agency, based in C.E. 578, operated independently for greater than 1,400 years earlier than it grew to become a part of the Takamatsu Development Group in 2006. Adapting throughout huge social and political transformations, the Catholic Church, France’s Hôtel-Dieu hospital (C.E. 651) and Morocco’s College of al-Qarawiyyin (C.E. 859) have every endured for greater than a millennium. Bali’s subak irrigation system, established within the ninth century, continues to flourish via a community of water temples that unite ecological engineering with Hindu philosophy and ritual. In New Mexico, three-century-old acequia canals nonetheless perform underneath group governance, with elected mayordomos overseeing water sharing via collective labor. In Australia, the Brewarrina fish traps have been maintained throughout numerous generations of Aboriginal peoples. What ideas of intergenerational adaptation, renewal or continuity may NWMO glean from such long-lived methods?
The Reminiscence of Mankind (MoM) mission in Austria is also instructive. MoM’s mission is to protect a snapshot of human civilization for the distant future, a cultural time capsule designed to outlast struggle, decay and digital obsolescence. Deep contained in the Hallstatt salt mine, MoM shops ceramic tablets engraved with texts and pictures engineered to withstand warmth, radiation, chemical compounds and water. Its archive consists of all the pieces from scholarly works to recipes and private tales. Led by ceramist Martin Kunze, MoM represents a philosophy of strategic redundancy. To protect towards loss, Kunze distributes miniature tablets worldwide, every etched with maps pointing again to the Hallstatt archive—a bodily embodiment of a precept articulated by the digital-preservation mission LOCKSS: “A number of Copies Preserve Stuff Protected.” What may it imply for Canada to use that very same precept to the problem of nuclear reminiscence?
Indigenous cultures supply one other paradigm of long-term message endurance: storytelling as recordkeeping. Aboriginal Australian oral histories recount volcanic eruptions in western Victoria that align with geological proof courting again almost 37,000 years. Narratives describing islands drowned by rising seas have likewise been corroborated by local weather science. Such traditions display that oral information of environmental change can persist throughout timescales that far exceed these of our most superior digital media, which regularly decay or grow to be unreadable inside many years. What may NWMO study from cultural methods of reminiscence grounded in ceremony, cosmology and story transmission?
If constructed correctly, NWMO’s deep geological repository will outlast governments, economies and the very languages that title it. It would be a part of a world lineage of reverse arks: monuments to societies that dared to suppose past themselves. If the power is sometime uncovered by a far-future archaeologist, its depth, placement and engineered obstacles might reveal what our civilization judged to be harmful, how we calculated threat and the way we imagined future people would suppose, stay and interpret indicators. But scientific literacy can’t be assumed throughout deep time. Even the mightiest empires have cycled via collapse and renewal, via forgetting and rediscovery. To posterity, a nuclear waste repository may be learn as a sacred monument, an extraterrestrial stronghold, an odd geological formation, a chamber of forgotten gods—or one thing past our present-day creativeness altogether.
In the long run, Canada’s proposed Ignace repository will probably be an artifact of our personal self-understanding: stone and steel customary right into a sign meant to traverse huge orders of time. Its interpretation will belong solely to the long run—to no matter beings, human or in any other case, might sooner or later unearth what we as soon as selected to cover.
