Discussion Overview

The discussion centers around the concept of a subcritical reactor, specifically the "rubbiatron" or "rubiatron," which utilizes proton-driven thorium fission for the transmutation of nuclear waste. Participants explore the mechanics of the reactor, its potential benefits, and the implications of using thorium as a fuel source.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant describes the mechanism of the reactor, noting that protons interact with lead to produce neutrons, which then interact with thorium.
  • Another participant provides a link to a decay chain resource, suggesting it may help clarify the elements produced from thorium decay.
  • A participant identifies the reactor as a subcritical design aimed at transmuting nuclear waste.
  • One contributor expresses support for proton-driven thorium fission, highlighting its safety due to the non-runaway nature of the reaction and the production of waste with shorter half-lives.
  • Another participant shares a personal anecdote about discussing the reactor with Carlo Rubbia, indicating a shift in their perception of the idea.
  • One participant reflects on the potential value of nuclear waste and the abundance of thorium compared to uranium, suggesting that current waste management strategies may be unnecessary.

Areas of Agreement / Disagreement

Participants express a range of views on the reactor's design and its implications, with some supporting the concept of proton-driven thorium fission while others raise questions about the specifics of the decay products and the overall feasibility of the approach. No consensus is reached on the broader implications or the practicality of the reactor.

Contextual Notes

Some claims about the elements produced from thorium decay remain unspecified, and there are unresolved questions regarding the technical details of the reactor's operation and its potential advantages over traditional nuclear reactors.

It use small accelerator of protons and target of lead.
The lead give out neutrons, these neutrons go to thorio.
The thorio decay in other elements that now I don't know.
Does some body know this elements ?

I saw.
Thanks
 
he refers to the "rubbiatron" or "rubiatron", a subcritical reactor oriented to transmutation of nuclear trash.
 
I think proton driven thorium fission is a really nice idea. No chance of meltdown since it isn't a runaway reaction (it needs to be driven by the proton beam) and waste products with much shorter half-lives.

I must admit to initially being put off by it being promoted by Carlo Rubbia, since he can be a bit odd, but I chatted with him about it in Stockholm not too long ago, and he convinced me that it is a nice idea.

I've always felt that our old nuclear waste would one day be considered valuable, and that trying to hide it underground for 100,000 years was unnecessary.

And the planet has 550 times as much thorium as uranium.
