No they aren’t. It’s electrons from radioactive decay.

No fission.

Not Finnegan’s Wake though. You start reading 25% in, you won’t have a clue what’s going on.

Oh, yeah, as you were.

Crime And Punishment is boring.

I spent most of the book wishing Rashkolnikov had topped himself.

But someone will have to service them, repair stuff, all that malarkey.

Close or not, people will still have to go near them, so you need shielding. Cooling will be a lot easier mind you, assuming you’re taking advantage of the craters where no sunlight ever shines.

No it isn’t. For the last time. No atoms were split, therefore it’s not a fission reactor.

The US navy has 90 reactors, plenty enough to make a design profitable, the all use real fission reactors. If you use reactors near people, they need shielding, cooling, and all the stuff that goes with it.

“Targeting” “designs” yeah, get back to me when any of this stuff actually works.

Magnox reactors. “Electricity too cheap to meter.” I’ve heard this stuff before.

No it isn’t. No atoms are split. It’s just uses electron emissions to create heat.

They’re great for space probes, but considering they have been around since 1970, and have never been used anywhere near people, I assume they have a whole world of problems with organic matter.

That’s not fucking normal. Any of it.

Forget it mate. It’s Kettering.

If you want a fission reactor in the moon, you better be talking about the scale I’m talking about.

Artemis, in theory, can carry 27t to the moon, including crew.

As I said, good luck with that.

TOPAZ-1? Not a fission reactor. It’s a thermionic one.

1

John O’Donnell @jodami.bsky.social · 6h

There is no rocket that is even close to its capacity around these days

Also, the US landed six times on the moon, then cancelled the rest because it was too expensive

Now you are saying they’ll do, what, 15? 20? 30? And that’s just for a power plant. Assuming that all the parts are within payload

Low gravity. Dealing with a radioactive core outside a specialist factory.

This is assuming you’ve already built somewhere to put it first, and have made it proof from solar radiation, and oxygenated properly, otherwise you’re in spacesuits.

Also a Saturn V could carry 50t to the moon.

The smallest fission reactor I’ve seen is the 500t IMSR that is under development at the moment.

The Soviets had RTGs, but they aren’t fission reactors, they’re thermal ones.

I’d like to see people trying to build a nuclear reactor on the Moon, I’m sure they’ll be fine.

1

John O’Donnell @jodami.bsky.social · 8h

The lightest fission reactor still weighs 700 tons.

How do you expect to transport that to the Moon?

The reactors that satellites and probes use are thermal reactors, completely different.

1

John O’Donnell @jodami.bsky.social · 8h

One thing I know about nuclear reactors is that they are heavy.

You are still going to have to shield the reactor even on the Moon, radioactivity doesn’t abhor a vacuum.

Can he tell me how he’s going to get thousands of tons there?

She pops up, in a slightly bigger role, in the episode Starship Mine, and she is not alone in Sci Fi stars of the future in that episode.

Daniel Day-Lewis may be a bit of an exception.

To think he wanted to play Vincent Vega in Pulp Fiction. That would have been awesome, and we would have been spared Battlefield Earth and Gotti too.

If you’re going to Newmarket from London, you go through it.

They broke the law. If I was Reeves I’d tell them that they should be thankful that the police aren’t doing a criminal investigation into who authorised it.
