Intrinsically safe from meltdown

Radioactivity largely confined in melt - low vapor pressure

Minimum fissile inventory

Fast boron injection available

Minimum excess reactivity and rest heat in accidented core  

Completely remote monitor and control

Eventually fuelled for life without any further need of human intervention

Non-operational crystallized salt melt stable for years before site decommisson

All nuclear grade work orders can be handled by expert during maintenance inspections

Simple procedures to confine small quantities of poisonous flourides and fission products

Start charge and uranium233 dissolved in cubic meters of 450- 700degC salt melt

Uranium233 recognized as unsuitable as weapons material because of decay heat and intense gamma radiation

Time window for freshly bred uranium233 as terrorist weapons material can be further mitigated by ionium doping or uranium238 denaturing

Fast denaturation injection available

Low thermal neutron flux out of core for un-authorized parasite breeding

Dirty nuclear or chemical bomb ineffective 

Absolute minimum of nuclear waste

Waste handling dimensioned for the short lived Fission Products, the fissioned component

Only negligible levels of High Level Waste, the unfissioned component

No need for large cooling water reservoirs

Absolutely no CO2

Minimum inventory of poisonous chemicals

Minimum need for special steel, concrete, processing acids, fluorine, light elements
