Fact checking of claims about nuclear power projects

It really does seem relatively easy to raise money in nuclear power for making a few dubious claims about factory production, reactor performance, and delivery timeline.

In the industry, we call the 10 years it takes to realize that it's a lot harder than newcomers initially think, and that the people who tried in the past didn't fail merely because they were idiots who didn't think about economics: "getting run over by the nuclear bus".

After 15 years professionally in the industry, I'm just amazed that Rickover wrote his paper reactor memo back in 1953! https://whatisnuclear.com/rickover.html

The only way to win here is to make it expensive to produce lies . Make people take responsibility of the consequences and punish them .

Fact-Checking the Fact-Checkers initiates infinite recursion... Specifically, the section on the 'audacious claim' that small modular reactors generate more long-term waste (per unit of energy generated) than much larger traditional reactors does seem to have some support [1], based on issues like irradiation of the support structure (possibly more support structure is needed for many small reactors vs. one big reactor, plus the small structure might get a higher net flux of neutrons), and cases where sodium metal coolant is used as it becomes lowishly radioactive. The tradeoff I suppose is less risk of meltdown in the small modular designs?

The latest pebble-bed SMR designs avoid some of these problems as they use helium as the coolant, but similar efforts in South Africa failed several decades ago as the graphite pebbles broke down and graphite dust (and fuel particles) clogged the system. Now several plants in China and Canada using pebble-bed are currently in the works or operational (notably the one in China passed a natural-cooldown-after-loss-of-power test, i.e. no need to fire up a diesel generator to keep the coolant flowing to prevent meltdown[2]). However, there could be other catastrophic scenarios, as graphite is flammable and when hot reacts with water to form hydrogen. Loss-of-coolant >20% seems bad[3].

"Fact checking" as a means of combating mis/disnformation is kinda doomed from the start. The whole reason you're fact checking in the first place is because some nugget of bullshit was put into some large distribution channel and the damage is already done. Nobody reads the retraction, fact checkers by their very nature have smaller reach than the misinformation they're chasing.

The Wikipedia list of common misconceptions are still common and a lot of them are embarrassingly old if you believe that correcting misinformation is something that's possible to achieve on any scale other then waiting for people to die and hoping the next generation learns the right thing this time round.

God I'm so tired of fact checking.

First of all you cannot fact check an opinion. You can talk to the person and argue that, *IN YOUR HUMBLE OPINION* they're wrong. You can even present additional information that you think should help the person to change their mind, but you cannot expect it to happen, especially not at once.

Also, it doesn't matter as much WHAT you say but HOW you say it. Approaching someone for a discussion is one thing, attempting to be Einstein that knows everything better and presents everything he says as fact usually creates a defensive demeanor. Especially as journalists, that usually know jack shit about anything and happen to fail to reproduce even simple information correctly when depicting a story.

Then there’s another problem: A lot of people argue with science w/o even remotely understanding what science is. They present a lot of stuff as facts when suddenly a new player appears: progress. And that player can turn a lot of so called “facts” into questionable information. That’s the moment when it’s not about facts anymore but about the question how fast the information traveled and who it reached first.

So while a journalist is still stuck in the past, does fact checks that get a lot of posts/comments deleted on a website, others have already gotten to the new information and are trying to have a discussion on that, which is then successfully prevented by the fact checking journalist. When the new information has reached the journo 12h later, they don’t see themselves being responsible for anything…

But it’s not even that. A lot of science has been tainted by politics/ideology and is not in the least objective anymore, because the people in it are trying to further a political or ideological agenda. Which creates a whole new problem.

I could come up with many more examples here why fact checking is one of the worst ideas in human history, but it all boils down to one question: Who is in possession of the so called truth?

While the idea of fact checking is honorable, the simple information that there is no higher instance that holds the “ultimate truth” and that is not “politically or ideologically tainted” in one way or another should make it clear to anyone how bad the idea is once it’s put into action.

Not to mention how tinfoil hat connoisseurs behave once a fact check turns out to be wrong.
