hahahahah. Uhm ... To the author - the core of a "molten" salt reactor is already melted down. If its not melted down, its not working.
Something not mentioned in the article is that a LFTR can take what we now consider to be nuclear waste and use it as fuel - beat guns into plowshares as it were.
On average 96% of the initial fuel energy content remains in spent fuel assemblies, pulled due to accumulation of neutron absorbing contaminant reaction products. Decades worth of accumulated spent fuel once destined for “Yucca” can be re-purposed as a fuel source.
When Thorium breeding of fuel becomes necessary/ desired, the 3400# of pure U233 stockpiled will fulfill its most favored role.
