China plans world’s first fusion-fission power plant

Not that I'm aware of. All our power plants are just plain old nuclear energy boiling water. We're gonna use a damn Dyson Sphere to boil water......
We have bombs that use a similar starting mechanism, but they aren't exactly useful energy production.

They don't usually go boom so much as ticky ticky ticky on the Geiger counters, maybe a little glow in the night too...

wrote 6 days ago last edited byNot sure if you're being sarcastic but boats splitting in half is not uncommon, as far as boat structural failures go it's a relatively common one.
Stats on such a thing are unavailable but there are many news articles regarding boats splitting in half. I'd hope the safety factor on a fission reactor is several orders of magnitude higher than a seafaring vessel.

The fusion-fission hybrid will use high-energy neutrons produced by a fusion reaction to trigger fission in surrounding materials thereby boosting energy output and potentially reducing long-lived nuclear waste.

I'm pretty sure they aren't doing the design part of the research. A lot of the "new" designs that China has been testing recently, have been sitting on US and European shelves for decades, like since the late '60s and early '70s. There's just not really a way, in the West, to legally set up a test reactor. China can just ignore things like permits and zoning.
wrote 6 days ago last edited byThis is one of the biggest frustrations with nuclear power. The first power plants had issues (mostly due to them being bomb factory designs). We learnt from that, and designed better ones. They never got built. They were swamped in red tape and delays until they died.
Decades later, China comes in and just asks nicely. The designs work fine. China now leads the way, built on research we left to rot.
It's also worth noting that there is a big difference between a fusion power plant and a fission one. China is doing active research on it, as is the west. There's quite a friendly rivalry going on. We have also basically cracked fusion now. We just need to scale it up. The only big problem left is the tokamakite issue. The neutron radiation put off by the reaction transmutes the walls. Using radioactive materials as a buffer is an idea I've not heard of. I'm curious about the end products. A big selling point of fusion is the lack of long term waste. Putting a fission reaction in there too might lose that benefit.

It's... It's well within limits. Sustaining sequence.
Oh. Oh dear.

i had no opinion and minimal knowledge about high speed rail in China going into this comment section, but it looks like the outer cities experience real estate growth in the wake of being connected by high speed rail, and reportedly the rail lines are some of the safest in the world. i can't imagine criticizing a country for building too much high efficiency mass transit in advance

I mean the Nazis did that in preparation for their Blitzkrieg and the Holocaust so there are real examples why building seemingly overengineered and overly excessive infrastructure can be problematic. And besides a demonstration of power, I think some of those railways are exactly that. To transport troops or masses of prisoners quickly and efficiently. God knows they have enough of those.

Yes, the uranium tamper in a fusion weapon. Half of the energy in a fusion weapon comes from fast neutron fission, mostly in U-238. It's not a chain reaction.

Wait wait wait wait.
Don't we already do this? Just right now we don't do it in the same reactor?

wrote 6 days ago last edited byIt was a joke. We have invented fission and fusion, but the reactors are still attached it to a Rankine Cycle.

I'm sure China will share a lot of technological innovations as well

All told, I wouldn't be surprised if a greater percentage of reactors have melted down than big ships have split at sea.

Sounds like you're just undoing your work. Put the pieces together, take them apart again. Energy!
Wake up babe new perpetual motion dropped!
