The DREAM disruption simulation model and the SOFT synthetic synchrotron diagnostic framework are used to assess the feasibility of the EDICAM visible camera system for runaway electron detection on JT-60SA disruption. DREAM is used to simulate a massive material injection induced disruption, starting from the high current scenario 2 from the JT-60SA research plan. The amount of the injected argon gas is chosen to generate a significant runaway population. The resulting distribution function and the EDICAM camera parameters are given as input to SOFT to simulate the expected radiation image. It is found that the EDICAM system can be used to detect runaway electrons in a JT-60SA disruption, but the determination of the detection limits requires careful consideration of background plasma emissions and camera characteristics.
