Korea Advanced Liquid Metal Reactor

The main objectives of the R D program and a tentative schedule with 5 progressing stages for the development of KALIMER(Korea Advanced Liquid MEtal Reactor) are given and the current LMR experiences are briefly described. 

The construction of a prototype or demonstration type KALIMER(Korea Advanced Liquid MEtal Reactor) is essential to accomplish the goal of the LMR development. For the construction time, the year 2011 is suggested as established in the LMR long-term development plan. 

KOREA ADVANCED LIQUID METAL REACTOR (KALIMER)... 

The LMR design technology development project was approved as a national long-term R D programme in 1992 by the Korea Atomic Energy Commission (KAEC), which decided to develop and construct a liquid metal cooled reactor (LMR). Based upon the KAEC decision, the Korea Atomic Energy Research Institute (KAERI) has been developing KALIMER (Korea Advanced Liquid Metal Reactor) [XX-1, XX-2]. 

The break of a pipe reduces the core flow, which results in power-to-flow mismatch for some seconds after the pipe break occurred. However, the power is stabilized, even though the automatic reactor scram is not activated. The GEM play an important role in providing the dominant reactivity feedback in case of an important core flow reduction resulting in the decrease of the GEM level below the top of the active core. The results of the primary coolant pipe break event analyses performed for the Korea Advanced Liquid Metal Reactor (KALIMER), which adopts several advanced design features, prove both a coolant subcooling margin of more than 400 K, and a stable system response.
