“Nuclear Power Turns to Salt “, by James Conca  Contributor Jan 7 2015


        Advantages of the ISMR: 1. produces electricity cheaper than using coal, ( an objective is to produce energy cheaper than using natural gas ) 2. creates much less waste and few long -lived radioactive elements. 3. uses almost all of the fuel, which lasts for 7 years ( without refueling,) and (the remaining fuel) itself can be recycled 4. is modular, from 80 MWt to 600 MWt  , able to be combined and adapted to individual needs for both on and off -grid heat and power 5. is small enough to allow fast and easy ( factory) construction, and trucking to the (construction ) site 6. operates at normal  ( ambient) pressures , removing those (containment) safety issues, and at higher temperatures making it more energetically efficient 7. has the type of passive safety features that make it walk-away safe 8. does not need external water for cooling 9. can load follow rapidly to buffer the intermittency of renewables.

The general facility layout for Terrestrial Energy’s new Integral Molten Salt Reactor, showing theIMSR core-unit within its below-ground containment cavity, overhead office and control areas, storage silos, separate steam generator and turbine areas, and delivery-removal area for new and used core units. The reactor is flexible, redundant and passive.
