A wildfire burning near the desert birthplace of the atomic bomb advanced on the Los Alamos laboratory and thousands of outdoor drums of plutonium-contaminated waste Tuesday as authorities stepped up efforts to protect the site from flames and monitor the air for radiation.

Officials at the nation's premier nuclear weapons lab gave assurances that dangerous materials were safely stored and capable of withstanding flames from the 93-square-mile (240 square kilometer) fire, which as of midday was as close as 50 feet (15 meters) from the grounds.

I'm trying to decide if we're hearing these stories because of what happened in Japan, or if it's just continuing to be a bad year for the nuclear industry.

So John Oliver did a show on nuclear waste

And he's gotten flak for it. Having an acquaintance that works in the field of Nuclear Waste, and seeing the reaction of him and others in the field on social media, the reaction seem to be the same - a lot of criticism that he didn't have any experts in the field in the show, and that there was a lot of fear mongering.

While I generally like the show, there's been at least a few other times I've been unimpressed with it's coverage.

Of course he can be criticized. And I can criticize the critics. And you can criticize me. Do you see how that works?

I agree with Moliere. John Oliver does do some amazing shows, but sometimes he's wrong. I've read a number of scientists that echo some of those same criticisms. I think that an even handed reading of the evidence probably shows he's incorrect about some of the things that were on this weeks episode, and that deserves to be called out.

John Oliver makes his living by blurring the line. It's valid criticism that he should be factually correct even if he may want to exaggerate for effect.

Was he factually incorrect in the nuclear waste segment? A barely-hinged twitter rant from an industry insider, making claims such as dumping drums of low-grade waste in the ocean is harmless (If so, why was it globally banned? Was shooting holes in the drums that didn't sink on their own a really well-thought out course of action?), didn't strike me as particularly compelling evidence to that end.

I agree. When he's doing these sorts of pieces, it's not primarily about the satire. It's primarily about him trying to inform his audience. Which is fine, but he should actually inform them.

Is there some logical reason that something cannot both be true and presented in a comedic context? The only thing I care about is that I found the segment to be entertaining, and as a simple layman I didn't spot any obviously fallacious information. That meets my standard for a comedy show. If I wanted an in-depth treatment of the subject, I'd hunt up some documentaries or crack open a book or three. I wouldn't rely on a comedian to do my homework for me.

If he lied about anything, then by all means use your vastly superior knowledge and rhetorical talent to enlighten me.

Oh, hey, while we're at it, where is the condemnation of Charleston's Post and Courier for their irresponsible reporting of radioactive alligators earlier this year?
The U.S. then shipped 1,500 tons of tainted soil back to the states for disposal. The 55-gallon steel drums of radioactive dirt were buried at the Savannah River Plant in 20-foot-deep unlined trenches.

That burial ground is where the plant dumped much of its solid radioactive waste at the time, often in cardboard boxes. Radioactive contamination continues to leach from burial trenches into groundwater and periodically the Savannah River despite efforts to cap the trenches and stem the leakage. Plant engineers built a dam to block most of the flow and create a large pond.

The contaminated pond water is used as irrigation and regularly sprayed into the surrounding forest where it is absorbed by the trees and evaporates harmlessly into the atmosphere. The pond also is home to two radioactive alligators dubbed by workers as Tritagator and Dioxinator — after two of the wastes, radioactive tritium and toxic dioxin.

Solid radioactive waste continues to be dumped into unlined ditches and buried. But now it’s limited to low-level radioactive material with short half-lives — the time it takes for the material to lose half of its radioactivity. Plant officials say the material loses virtually all of its radioactive punch before it can leach into groundwater and spread very far from the trenches.
Since the idea of "radioactive alligators" is just silly nonsense, I'm sure folks that are all up in arms about this would be just fine with taking a dip in that pond. :)

On a related note, Vanity Fair has a very good (long) article about the DOE. Why the Scariest Nuclear Threat May Be Coming from Inside the White House
On the morning after the election, November 9, 2016, the people who ran the U.S. Department of Energy turned up in their offices and waited. They had cleared 30 desks and freed up 30 parking spaces. They didn’t know exactly how many people they’d host that day, but whoever won the election would surely be sending a small army into the Department of Energy, and every other federal agency. The morning after he was elected president, eight years earlier, Obama had sent between 30 and 40 people into the Department of Energy. The Department of Energy staff planned to deliver the same talks from the same five-inch-thick three-ring binders, with the Department of Energy seal on them, to the Trump people as they would have given to the Clinton people. “Nothing had to be changed,” said one former Department of Energy staffer. “They’d be done always with the intention that, either party wins, nothing changes.”

By afternoon the silence was deafening. “Day 1, we’re ready to go,” says a former senior White House official. “Day 2 it was ‘Maybe they’ll call us?’ ”
After painting a picture of an agency in existential crisis, it goes into the top five threats that the DOE confronts. Nuclear waste management is among them.

You're reading too much into the segment, it's not a super serious hour long documentary, it's just an alert that there's a lot of nuclear waste that hasn't been safely disposed of. It could, and should, be more accurate, but using the expression "low level waste" by a professional is just worse. It still kills you and makes your life dreadful and painful until you die.

The dream of pollution and radiation-free electricity derived from nuclear fusion could be a step closer to reality thanks to a breakthrough by British scientists.

They have developed an exhaust system that can deal with the immense temperatures created during the fusion process and which so far have limited the viability of commercial fusion power plants.

Commonwealth Fusion Systems and the MIT Plasma Science and Fusion Center have made encouraging progress toward SPARC recently. The goal is for SPARC (a demonstration reactor) to achieve net-positive energy in 10-or-so years, with commercial ARC reactors coming online within 15 years.
What is new? What makes this new path possible now?

The SPARC approach uses a newly available superconducting material that allows operation at much higher magnetic fields than the previous state-of-the-art. Superconducting materials are required in fusion energy systems as no electrical power is required to operate the magnets that provide the plasma containment; the high magnet fields are critical because they dramatically reduce the volume of the plasma at a fixed fusion power output. This combination makes a net-energy fusion device, such as SPARC, much smaller and less expensive than if it were built with the previous magnet technology. As a result, smaller and much more streamlined organizations, such as MIT and CFS, can pursue net energy fusion devices. This is not to say success is guaranteed; but the cost and timescale to retire key technical risks becomes acceptable to private-sector investors.

Both the ITER and the SPARC proof of concept reactors are expected to be online in '25/'26.

Just 4-5 years. At that time, throwing money at them should work.

The cold fission problem. There is very little waste produced by Nuke power, but the amount of power required by a jet takeoff (Air travel being 1/3rd of emissions) most of those emissions are in the takeoff. W/O cold fusion or solid state batteries you cannot solve the huge energy output required by jet takeoffs.

Putting nuke plants in airplanes right now wouldn't solve that and every plane that crashes has the potential to be a dirty bomb.

Regarding the issue of fission waste, it may be small in volume, but it isn't insignificant.

Fission reactors produce deadly waste. Fusion reactors wouldn't, but we haven't yet figured out how to make fusion efficient enough to produce more power than it requires.

Fusion power gets us to Star Trek's UFP, but we don't yet know if it's possible.

Right now, we're developing hybrid planes that will use jet engines for takeoff and electricity for cruising. No existing electric tech can deliver enough thrust for takeoff, nor is there anything on the horizon, but they can maintain speed and altitude after jet fuel does the literal heavy lifting. Some concepts NASA is working on.
