Nuclear - Blog Posts

I've recently been seeing this article making rounds around this website and particularly people misusing this very cool advancement to imply that modern nuclear reactors are "unsafe" or "dangerous", which is partially due to the just blatantly bad journalism on display here.

The accomplishment of this new reactor is definitely exceptionally impressive but I think that news websites (Even ones specializing in science) have been mischaracterizing the reactor as "meltdown-proof" which is just - wrong? and implies that current reactors are just begging to meltdown.

The cool thing about this new reactor is that its passively cooled, but that doesn't mean its INVULNERABLE to nuclear meltdowns, for example the Chernobyl meltdown happened completely independently of whether it was cooled passively or not.

In fact, passive cooling would only pose an advantage in situations where ALL pumps and backup pumps break and the core doesn't get coolant pumped to it. That's happened exactly once: in Fukushima and only after a literal tsunami hit it, and there's no reason to think that the passive Helium coolant in this new reactor wouldn't also just break. Fukushima happened because of corruption in regulation, preventing suitable defenses against this exact thing from getting built, not because of unsafe reactor design.

There's also some articles like this one which talk about the new reactor being "self-regulating" which is true, but misses the point that the vast majority of nuclear reactors in service today are also stable in the exact same way. Negative feedback loops are a HUGE part of reactor design, the most popular reactor design today is the Pressurised Water Reactor (PWR) which is incredibly stable - PWRs just truly hate increasing (or decreasing) energy output.

Most nuclear reactors today are already incredibly safe, even if you had complete control over a nuclear reactor it would be effectively impossible to cause a meltdown on purpose - both the physics of the system and the thousands of automated components would beat the ever loving shit out of any hope of trying to do so.

Articles like these just turn this impressive achievements into a kind of fearmongering over the "dangerous" nuclear reactors currently being used. The fact is that nuclear reactors are incredibly safe, PWRs are an incredible feat of engineering genius and its a genuine shame that the general public isn't aware of how much care goes into their design and safety, let alone how useful and essential they are in our electrical systems.

Modern nuclear reactors are clean, they are safe, and they are vital to a healthy energy grid in the post-fossil-fuel future.

A really good read I highly recommend is Colin Tucker's How To Drive A Nuclear Reactor. He's very clear and very frank with the workings and reality of nuclear power today.

Ladies and gentlemen, this is why I'm pro-nuclear reactors. Seriously, stop bringing up Fukushima and Chernobyl for reasons why we should demonize this energy source. Accept the problem is the coal and fossil fuels and start replacing them with nuclear reactors, solar panels, hydropower plant, and wind turbines. Stop letting these freak accidents scare you into avoiding nuclear as an option because nowadays with the safeguards we have in place at modern-day reactors, the chances of a disastrous meltdown happening like that are so astronomically low that it may as well be zero. You want clean energy? Go nuclear and maybe we might actually have the chance to reverse some of the damage we have brought upon the planet we live on.

That probably explains why I write magic the way I do.

Honestly, the fact that terry Pratchett has experience around nuclear power makes so much sense once you realize what magic is standing as a metaphor for in the discworld. Like, look at this fucking quote from going postal:

"That's why [magic] was left to wizards, who knew how to handle it safely. Not doing any magic at all was the chief task of wizards—not "not doing magic" because they couldn't do magic, but not doing magic when they could do and didn't. Any ignorant fool can fail to turn someone else into a frog. You have to be clever to refrain from doing it when you knew how easy it was. There were places in the world commemorating those times when wizards hadn't been quite as clever as that, and on many of them the grass would never grow again."

Like... It feels incredibly obvious what he's talking about once you know the context.
