There are issues I’ll all the time bear in mind from my time in New Mexico. The manner the bark of towering ponderosa pines smells of vanilla once you lean in shut. Sweeping vistas, from forested mountaintops to the Rio Grande Valley, that embellish even probably the most mundane procuring journey. The trepidation that comes with the tendrils of smoke rising over close by canyons and ridges through the dry, wildfire-prone summer season months.
There had been no main wildfires close to Los Alamos National Laboratory through the yr and a half that I labored in public communications there and lived simply throughout Los Alamos Canyon from the lab. I’m in Maryland now, and social media this yr has introduced me pictures and video clips of the wildfires which have been devastating elements of New Mexico, together with the Cerro Pelado hearth within the Jemez Mountains simply west of the lab.

Wherever they pop up, wildfires can ravage the land, destroy property and displace residents by the tens of hundreds. The Cerro Pelado hearth is small in contrast with others raging east of Santa Fe — it grew solely to the scale of Washington, D.C. The hearth, which began mysteriously on April 22, is now principally contained. But at one level it got here inside 5.6 kilometers of the lab, severely threatening the place that’s accountable for creating and sustaining key parts of fusion bombs in our nation’s nuclear arsenal.
That shut name could also be only a trace of rising hearth dangers to return for the weapons lab because the Southwest suffers within the grip of an epic drought made worse by human-caused local weather change (SN: 4/16/20). May and June usually mark the beginning of the state’s wildfire season. This yr, fires erupted in April and had been amplified by a string of heat, dry and windy days. The Hermits Peak and Calf Canyon fires east of Santa Fe have merged to develop into the biggest wildfire in New Mexico’s recorded historical past.
Los Alamos National Lab is in northern New Mexico, about 56 kilometers northwest of Santa Fe. The lab’s major efforts revolve round nuclear weapons, accounting for 71 p.c of its $3.9 billion funds, in accordance the lab’s fiscal yr 2021 numbers. The funds covers a ramp-up in manufacturing of hole plutonium spheres, often known as “pits” as a result of they’re the cores of nuclear bombs, to 30 per yr starting in 2026. That’s triple the lab’s present functionality of 10 pits per yr. The website can be residence to radioactive waste and particles that has been a consequence of weapons manufacturing for the reason that first atomic bomb was in-built Los Alamos within the early Forties (SN: 8/6/20).
What is the hazard as a result of hearth approaching the lab’s nuclear materials and waste? According to literature that Peter Hyde, a spokesperson for the lab, despatched to me to ease my concern, not a lot.
Over the final 3½ years, the lab has eliminated 3,500 tons of bushes and different potential wildfire gasoline from the sprawling, 93-square-kilometer advanced. Lab services, a lab pamphlet says, “are designed and operated to protect the materials that are inside, and radiological and other potentially hazardous materials are stored in containers that are engineered and tested to withstand extreme environments, including heat from fire.”
What’s extra, most of roughly 20,000 drums stuffed with nuclear waste that had been saved beneath tents on the lab’s grounds have been eliminated. They had been a trigger for nervousness over the last main hearth to threaten the lab in 2011. According to the latest numbers on the challenge’s web site, all however 3,812 of these drums have been shipped off to be saved 655 meters underground on the Waste Isolation Pilot Plant close to Carlsbad, N.M.
But there’s nonetheless 3,500 cubic meters of nuclear waste within the storage space, in line with a March 2022 DOE strategic planning doc for Los Alamos. That’s sufficient to fill 17,000 55-gallon drums. So probably disastrous portions of comparatively uncovered nuclear waste stay on the lab — a single drum from the lab website that exploded after transport to Carlsbad in 2014 resulted in a two-year shutdown of the storage facility. With a complete budgeted cleanup price of $2 billion, the incident is likely one of the costliest nuclear accidents within the nation’s historical past.
Since the 2011 hearth, a wider buffer area across the tents has been cleared of vegetation. In conjunction with hearth suppression techniques, it’s unlikely that wildfire will likely be a hazard to the waste-filled drums, in line with a 2016 danger evaluation of utmost wildfire situations carried out by the lab.
But a February 2021 audit by the U.S. Department of Energy’s Office of Inspector General is much less rosy. It discovered that, regardless of the removing of many of the waste drums and the multiyear wildfire mitigation efforts that the lab describes, the lab’s wildfire safety remains to be missing.
According to the 20-page federal audit, the lab at the moment had not developed a “comprehensive, risk-based approach to wildland fire management” in accordance with federal insurance policies associated to wildland hearth administration. The report additionally famous compounding points, together with the absence of federal oversight of the lab’s wildfire administration actions.
Among the continuing dangers, not all hearth roads had been maintained properly sufficient to offer a protected route for firefighters and others, “which could create dangerous conditions for emergency responders and delay response times,” the auditors wrote.
And a canyon that runs between the lab and the adjoining city of Los Alamos was recognized within the report as being full of 10 instances the variety of bushes that might be very best, from a wildfire security perspective. To make issues worse, there’s a hazardous waste website on the backside of the canyon that would, the auditors wrote, “produce a health risk to the environment and to human health during a fire.”
“The report was pretty stark,” says Edwin Lyman, director of nuclear energy security on the Union of Concerned Scientists. “And certainly, after all the warnings, if they’re still not doing all they need to do to fully mitigate the risk, then that’s just foolishness.”
A 2007 federal audit of Los Alamos, in addition to nuclear weapons services in Washington state and Idaho, confirmed related issues. In quick, it appears little has modified at Los Alamos within the 14-year span between 2007 and 2021. Lab spokespeople didn’t reply to my questions concerning the lab’s efforts to handle the particular issues recognized within the 2021 report, regardless of repeated requests.
The Los Alamos space has skilled three main wildfires for the reason that lab was based — the Cerro Grande hearth in 2000, Las Conchas in 2011 and Cerro Pelado this yr. But we most likely can’t rely on 11-year gaps between future wildfires close to Los Alamos, in line with Alice Hill, the senior fellow for power and the atmosphere with the Council on Foreign Relations, who’s primarily based in Washington, D.C.
The altering local weather is anticipated to dramatically have an effect on wildfire dangers in years to return, turning Los Alamos and surrounding areas right into a tinderbox. A examine in 2018 in Climatic Change discovered that the area extending from the upper elevations in New Mexico, the place Los Alamos is situated, into Colorado and Arizona will expertise the best enhance in wildfire chances within the Southwest. A brand new danger projection instrument that was advisable by Hill, known as Risk Factor, additionally reveals rising hearth danger within the Los Alamos space over the following 30 years.
“We are at the point where we are imagining, as we have to, things that we’ve never experienced,” Hill says. “That is fundamentally different than how we have approached these problems throughout human history, which is to look to the past to figure out how to be safer in the future…. The nature of wildfire has changed as more heat is added [to the planet], as temperatures rise.”
Increased plutonium pit manufacturing will add to the waste that must be shipped to Carlsbad. “Certainly, the radiological assessments in sort of the worst case of wildfire could lead to a pretty significant release of radioactivity, not only affecting the workers onsite but also the offsite public. It’s troubling,” says Lyman, who means that nuclear labs like Los Alamos shouldn’t be situated in such fire-prone areas.
For now, some dangers from the Cerra Pelado wildfire will persist, in line with Jeff Surber, operations part chief for the U.S. Department of Agriculture Forestry Service’s efforts to battle the fireplace. Large wildfires like Cerra Pelado “hold heat for so long and they continue to smolder in the interior where it burns intermittently,” he stated in a May 9 briefing to Los Alamos County residents, and to involved individuals like me watching on-line.
It will likely be very important to observe the footprint of the fireplace till rain or snow lastly snuffs it out late within the yr. Even then, some hazard will linger within the type of “zombie fires” that may flame up lengthy after wildfires seem to have been extinguished (SN: 5/19/21). “We’ve had fires come back in the springtime because there was a root underground that somehow stayed lit all winter long,” stated Surber.
So the Cerro Pelado hearth, and its occasional smoky tendrils, will most likely be part of life in northern New Mexico for months nonetheless. And the long run appears simply as fiery, if not worse. That’s one thing all residents, together with the lab, have to be making ready for.
Meantime, should you make it out to the mountains of New Mexico quickly sufficient, you should definitely sniff a vanilla-flavored ponderosa when you nonetheless can. I do know I’ll.
