Comment on China plans world’s first fusion-fission power plant

OK. Here’s the real question.
Are they sharing that research? I ask because if we can all get our heads out of our asses on energy production that kinda… wipes out a major reason for wars. Oh sure there are lots of OTHER reasons, but getting that off the table of excuses would be nice.
Also using fission materials as a way to shield the fusion reaction is a damned interesting way of getting around the spalling problem of the fusion reaction destroying its containment walls.

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.

This 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.

permits, zoning, human lives, environmental concerns…
Here’s hoping it doesn’t go boom.

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

The likelihood of one blowing its top is about as likely as the front of a boat falling off, which I’d like to make clear is very uncommon
