think assembly line (for instance one company wants to buy an old aircraft plant and set up mass production of small units that could fit in the bed of a pick-up truck)
all of the tech/design open sourced
imagine a third world country with little or no production (poor quality of life) getting access to practically unlimited energy (green no less)
we know energy is key to increasing life/health span (especially stabilizing population)
exponential technology/growth could dramatically increase the quality of life and environment
as i understand it the oak ridge project (mentioned in the article) used thorium and in the design (see lower left) is similar to this in that if there was a failure/emergency the freeze plug thaws and
the medium drains into the dump tanks and shut is certain (walk away safe) and the unit is still intact and unharmed
There have been other molten salt reactors. I think there was one used for tritium production. I'm no expert but I thought one of the downsides was that, if you did a complete cold shut-down, it was screwed forever.

The NRC recently published a letter from Terrestrial responding to the agency's Regulatory Issue Summary (RIS) published on 7 June last year. An RIS is an NRC request for information regarding future nuclear reactor licence filings.
In its letter, dated 18 November 2016, Terrestrial said it plans to submit an application to the NRC for a design certification or a construction permit "no later than October 2019".
Terrestrial included the status of the design, analyses, testing, licensing, and project planning for its Integral Molten Salt Reactor (IMSR), which is a liquid-fuelled, high-temperature, 400 MWt advanced reactor power plant design
Why is Terrestrial Energy's Integral Molten Salt Reactor a big deal ?
A molten salt 7.4 MWth test reactor was operated at Oak Ridge from 1965-1969. So no question about technical feasability
A conservative first IMSR design should be competitive with established power at about 3 cents per kWh
Later designs should be able to get lower than 1 cent per kWh
Design is walk away safe with passive safety systems
First designs would produce 6 times less nuclear waste and later designs can close the fuel cycle
Canada can use the first several hundred reactors to directly produce steam to profitably produce oil from the oilsands
Canada and Terrestrial Energy can thus use the oilsand reactors to profitably climb the learning curve before factory mass production of supersafe, super efficient and disruptively lower cost reactors
These system could provide 100% of global electricity demand without any emissions
Introduction to Terrestrial Energy • Terrestrial Energy • Commercializing a SMR for 2020s deployment - Cost-competitive with fossil fuel combustion - Ideal for industrial heat and SMR markets • Technology – next generation Molten Salt Reactor (“MSR”) • Proprietary MSR design – the Integral Molten Salt Reactor (“IMSR™”) • High technology readiness • Conducting basic/preliminary engineering work - Concludes with construction and licensing of the first commercial IMSR power plant (400 MWth reactor) • IMSR development and deployment • Supported by power utility industry and senior executives, industrial companies, environmentalists and the Canadian Government and DOE • Commenced VDR with Canadian Nuclear Safety Commission (“CNSC”) - First MSR vendor to commence regulatory process • Terrestrial Energy is a leading advanced reactor developer in a fast developing cleantech sector
Advantages of Molten Salt Reactors • Safety • Enhanced ability for passive decay heat removal • Inherent Stability from strong negative reactivity coefficients • Low pressure and no chemical driving force • Caesium and Iodine stable within the fuel salt • Reduced Capital Cost • Inherent safety can simplify entire facility • Low pressure, high thermal efficiency, superior coolants (smaller pumps, heat exchangers). No complex refuelling mechanisms • Long Lived Waste Issues • Ideal system for consuming existing transuranic wastes • Even MSR-Burners can close fuel cycle and see almost no transuranics going to waste • Resource Sustainability and Low Fuel Cycle Cost • Thorium breeders obvious but MSR-Burners also very efficient on uranium use
Terrestrial Energy Integral Molten Salt Reactor • LEU fueled MSR-Burner design like the 1980 DMSR • Integrates all primary systems into a sealed reactor Core unit • 7 year Core unit “Seal and Swap” approach to graphite lifetime • Shorter lifetime for vessel and HX simplify qualification • Planned as 400 MWth (~ 192 MWe) • Alternate salt and new off gas system • New passive decay heat removal in situ without dump tanks • Safety at forefront which leads to cost innovation
China knows they need to do something about air quality. They are also good at looking ahead to plan for long term economic advantage.
I've probably said before, I don't think nuclear is great (don't know enough about thorium to comment, I probably should do some reading sometime). However coal is the real scourge, and if people want the benefits of lots of energy supply they should be willing to take the risks of nuclear while working to modernize to safer designs.
I'm all in favour of increasing efficiency and renewables (well except for the environmental impacts of hydro) and investment in that area creates far more jobs than coal or petroleum. Still we are a long way from filling the demand.
i think there's some good news regarding all of this in that quite a few people are proposing small modular reactors
something that may be mass produced (assembly line) and transported relatively easy
so countries that aren't even on that map/chart could be an eventual prospect for such a product

Looks to me like China and India are planning on having plenty of electricity, maybe even enough to sell as a commodity. Russia is revamping their old infrastructure to be sure they aren't beholden to China to keep the lights on, they will probably be selling oil and gas to the US and the UK. France is a bit misleading because it's only thier very old reactors that are being phased out they have a new design (european pressure reactor) plant that is scheduled to come online soon but is held back by economics and politics right now - makes you wonder if they have presented to information in order to further a particular position...
i thought i linked the image to the article (now i'm not sure what site/article i plucked it from)
france is in the nuclear business in a big way
i think they may be the largest (or one of the largest) exporters of electricity - i'm sure they're getting paid)

Roger. France is in no way backing away from nuclear power:

Might it have something to do with making nuclear weapons? Just asking, I don't know.
Nah. You operate power reactors completely differently from a weapons production reactor, even if it is a design that is practical to use for both.

i wonder what this chart says about the future of nuclear energy?
