I think we are all interested in any new nuclear developments. I agree that if life is to stay as convenient as now, we need a baseload electricity supply. Maybe nuclear will be inevitable for that reason. I am expecting life to have far less convenience in the future.


Thank you for your open minded attitude towards this sometimes quite emotive subject. BTW, have you seen the Thorcon plans? It's a Molten Salt Reactor with all that safety, but mass produced in shipyards and deployed by boat. They're floating nuclear reactors that pilot into developing world harbours and plug into their grids at 7c kwh, projected of course. They're Canada based but aiming to sell to Indonesia within 7 years.

I note that you say "the Thorcon plans". It is yet to happen like so much in the nuclear and fusion field. Perhaps when there is actually a reactor on the ground that is actually producing electricity at a cost which is competitive and actually breeds and which is actually safe, all at the same time, we can start thinking about a future for the technology.

Hopefully the new reactors won't have to be sited on the coast where they are vulnerable to sea level rise and tsunamis.

Thorcon isn't a breeder. It's a short lived reactor that will be recycled after 10 years. It's got all the passive safety of a molten salt reactor, so if a tsunami knocked it out it would sink and the salt would 'freeze' into a solid at below 400c, and not go anywhere. Water is a great moderator of radioactivity, halving the radiation of something every 12 cm. A fatal dose is reduced to fairly harmless within the height of the average man.

Thorcon will float up with the sea level rise, just not an issue. In fact, ideal for it! Better than land reactors close to the ocean! But it produces waste, and that will need to go off to carefully placed MSCFR's that can burn up the waste.
