> ". In 2010 the International Panel on Fissile Materials said "After six decades and the expenditure of the equivalent of tens of billions of dollars, the promise of breeder reactors remains largely unfulfilled and efforts to commercialize them have been steadily cut back in most countries"."
I have been following FBR progress especially thorium based ones, as it was considered to be India's path to energy independence since the 1950's. The progress has been slow and expensive and still a lot of research is left to do, so to say meaningfully that waste will reduce is not a viable plan today or next 20 years.
