For the February 5th, 2020 DC ANS dinner meeting, Mr. Neal Mann and Dr. Mihai (Mike) G. Pop, will be speaking on:

“A proposed molten uranium metal fueled breed and burn reactor that consumes LWR UNF”

Click here for Mr. Mann’s and Dr. Pop’s full bio and meeting announcement.

The presenters are proposing a reactor design which combines elements of MSR and CANDU reactors with a novel control system in a reactor which uses molten uranium metal fuel in large fuel tubes. It can use LWR used nuclear fuel (UNF) (fissile content 1.4%) as its fuel with only reducing the oxides to metal, no other separation is required. The reactor uses large fuel tubes so that more of the emitted fast neutrons cause fast fission of U-238 to boost the neutron production enough to make breeding possible. With a breed and burn fuel cycle it has a fuel life that is longer than the reactor life, and the only waste is the fission products. The fuel at the end of reactor life has a higher fissile content than the starting fuel so it can be reused as fuel. The control method and reactor design provide a number of inherent safety features. The design poses a number of engineering and regulatory challenges, mostly related to the high fuel temperature.
