What ever happened to "Cold Fusion"?

Fusion is tough to get started, and very very tough to control. The main reason why it is considered better than fission, is there is a lot more of the fuel available. It is not cleaner.

Reactor walls surely get low-active from neutron bombardment. IF you use ordinary deuterium and not Helium-3. But difference between waste from fision and fusion is collosal. We are talking couple of tons of metal plating getting low-radioactive compared to hundreds of tons of highly radioactive uranium waste that is so hot it needs to be kept under water for many years before burried.

Heck, turbine piping and reactor containment in fision plant gets as radioactive as fusion tokamak chamber clading....then you have all fuel.

I'll give any Pelican member 100$ if you could create cold fusion. I got a big face hundred in my pocket just burnin' a hole in my pocket.

But seriously, cold fusion in my lifetime (especially in production) I will not see, and I am very young.

I have a question, a little OT, has Einsteins Theory of Relativity been proven yet? Just to get the "Theory" out of the way?

Turbine piping? NO!

The steam that runs the turbine at a nuke plant is isolated from the radioactive water through heat exchangers. I've worked on these turbines, I've tested them, they were always clean.

Most nuclear plants use a three-circuit system, IIRC.

The first circuit is the radioactive water that cools the reactor. It is run through a heat-exchanger with the second circuit, though is physically isolated from it. The second circuit is what actually leaves the containment building where it is run through heat exchangers with the third circuit (also physically isolated from each other). The third circuit is what actually runs the generation turbines.
