If we go with a pebble bed for example then the fucking plant literally can't melt down with or without power. There are many other designs that likewise are failsafe.
Proposed Pebble Bed Modular Reactors (PBMR) are designed with exactly the reduced containment that Chernobyl was built with. Proposed new generation 'once-through' reactor series like the AP-1000 are designed with significantly reduced containment. They have been designed this way to reduce the expense of building them, as the sheer volume of concrete required to build a reactor containment is one of the highest input costs as well as the third greatest contributor of greenhouse gasses.
There are a number of functional issues with pebble beds, like the mechanism jammin, which is what happened to the German PBMR. Also getting hundreds of thousands of the fuel balls uniform and of course the issues at the end of their service life with air leaking into the reactor and causing graphite fires.
I compare proposed PBMR designs with RBMK at Chernobyl. You know, graphite covered fuel kernels, helium gas cooled, no containment building required, produce deadlier waste and have deadlier failure modes.
IFR is a much better concept than PBMR, pity W. ordered it's demolition. Fantastic concept and actually worked. I was a big fan of the Integral Fast Reactor, and in a way I still am. But the reality is 3rd and 4th generation reactors are a pipe dream because our material science is not advanced enough yet to produce a reactor design that will overcome neutron bombardment. If you are going to build reactors then do it properly and build a Terra-watt scale nuclear reactor facility with an attached waste facility in the belly of a massive granite mountain that chomps up all your remaining plutonium or end all commercial nuclear activity altogether.
Most of the 100 odd reactors in the U.S are approaching old-age and have to be de-commissioned so it's a future, rather than obsolete, issue. If you want to build a modern Nuclear Industry it starts with the geology of the spent fuel containment facility. If you do it in granite then you could power the US for at least 5000 years. A properly functioning Nuclear Industry is important and the one we've got is a total mess heading for either complete failure or disaster.
This had no reason to be in a separate post. My other post to you addressed this issue. You're talking about old reactor designs.
An example of what I'd suggest for nuclear power:
You keep assuming I want to build 3 mile island.
The only reactors *legally* approved for construction is the AP1000 with all of the issues in the study. TWR is an interesting concept, however it doesn't exist, compared to IFR which *did* exist, functioned as planned, did what it was supposed to do yet was still funded for *demolition* by W.Bush.
Your position is out of date. Obsolete.
Your position is SyFy. Have you investigated the difference between a breeder and a burner reactor? Your argument is for breeder reactor with the same decommssiioning issues as current generation reactors, that doesn't exist and has no legal approval to operate? I think you'll find IFR is a vastly superior reactor design, that actually works and has all the features, and more(like built in medical isotope extraction) than TWR. Far from obsolete, my position is plausible.
