Core Design of a 600 MWe Uranium Fueled TRU Burner Reactor

The conceptual core design of the demonstration sodium cooled fast reactor (SFR) for TRU burning is being developed by the Korea Atomic Energy Research Institute (KAERI). The main objective of demonstration reactor for the construction and operation is to test and demonstrate TRU fuel, and the operation of the large sized (1500 MWth) sodium fast reactor and the TRU burning capability of commercial burner reactor. In this paper, a core design progress for the start core of the demonstration reactor is presented. It is scheduled to use the uranium fuel for the start core due to the uncertainty of the TRU fuel demonstration, and to change the LTRU core fuel from LWR spent fuel to the MTRU core fuel which consists of the LMR spent fuel and the self recycled fuel progressively
