The possibility of a small fast reactor was studied on the premise of metal fuel and Pb-Bi coolant uses. As a result of realistic RZ neutronic calculations using Monte-Carlo code MVPBURN, we confirmed that 10-year-long operation is possible without fuel exchange within less-than-1%dk excess rteactivity.
