Phenomenology of Graphite Burning in Air Ingress Accidents of HTRs

Figure 13

Schema of the HTR-Modul200 with flow pattern in assumed air ingress (a). Calculation results on core temperatures (b) and graphite burn-off in the central core axis (c) 20 h after air ingress start (air flow: A = 0.02, B = 0.3, C = 0.6 kg/s).
