The Monju advanced reactor simulator (MARS) has been operated for training of Monju operators and for verification of Monju operating manual's appropriateness since 1991 for over 11 years. This report covers transition of Monju training system and modified of MARS owing to Monju accident as operating experience of MARS on from 1994 to 2001. The principal points mentioned are as follows: (A)Improved Monju training system owing to Monju accident. (1)Reinforcement of sodium handling and sodium fire-fighting exercise (2)Improved of training system and revised of training frequency (3)Introduced of evaluation and analysis system regarding training results (4)Providing of training guide line (5)Step up of fundamental education by introducing of CAI (Computer Assisted Instruction System) (B)Upgrade of MARS for Monju restarting (1)Reflected of the real plant data obtained from Monju performance test (2)Addition of malfunction items (3)Development of simulation software and addition of simulation panel concerning reinforced sodium leakage corresponding training (4)Improvement of simulation ability and remodeling of calculating model by renewal of computer system (5)Up graded program in the future. Additionally, regarding operating experience of MARS before 1994 had been already reported named "Development and operation experience of a Full Scope Simulator for the Prototype FBR Monju", PNC ZN 2410-95-015.
