"Thousands of years." 🧵

"[I]n order to obtain significant reductions in total inventories of Am or other TRU, adv nuclear fuel cycles would have to be maintained for a very long period time – on the order of several hundred years."

—EPRI. Adv Nuclear Fuel Cycles… 2010.
https://www.epri.com/research/products/1020307 EPRI, 2010. Advanced Nuclear Fuel Cycles -- Main Challenges and Strategic Choices TRU burning in fast reactors is the only way to reduce the TRU inventories going to waste disposal using fission reactor technology. However, such reductions in the TRU content of HLW streams are counter-balanced by large increases in the total fuel cycle inventory of TRUs. For example, as far as Am is concerned, the comparison between once-through fuel cycle and TRU burning in Fast Burner Reactor shows a reduction of the inventory going to waste by a factor larger than 100. But it would take more than 108 years of operation at equilibrium to compensate for the higher Am inventory in the fuel cycle. These results indicate that in order to obtain significant reductions in total inventories of Am or other TRU, advanced nuclear fuel cycles would have to be maintained for a very long period time – on the order of several hundred years.

'For a Th-closed cycle the entire reactor fleet would need to be self-sufficient in fissile generation and operating on full actinide recycle. This appears quite remote and certainly very speculative. Even if pursued, it would require several decades, if not centuries, to unfold.'
https://www.researchgate.net/publication/362024722_Westinghouse's_fuel_cycle_strategy_towards_a_300-year_nuclear_waste Westinghouse’s fuel cycle strategy towards a “300-year” nuclear waste F. Franceschini¹, B. Lindley², C. Fiorina³, E. Lahoda¹, M. Wenner¹ ¹Westinghouse Electric Company, US, ²University of Cambridge, UK, ³Polytechnic of Milan, Italy Abstract This paper analyses a multi-tier reactor system devised for the recycling and transmutation of long-lived actinide components from used nuclear fuel. The first stage consists of current LWRs operating on UO2 fuel. The transuranic isotopes (TRUs) recovered via reprocessing from the discharged fuel are supplied to the second stage reactors where they are continuously recycled and incinerated. Reduced moderation PWRs with Th fertile carrier and liquid metal fast reactors with either U or Th fertile carriers have been A Th-closed cycle will not materialise as long as TRUs need to be burned and are supplied from the first to the second reactor tier, essentially implying that in order for a Th-closed cycle to occur the entire reactor fleet would need to be self-sufficient in terms of fissile generation and operating on full actinide recycle. This possibility at the current time appears quite remote and certainly very speculative, also even if pursued, it would require several decades, if not centuries, to unfold.
