中文摘要 | The 10MW high temperature gas-cooled reactor (HTR-10) steam generator tubing is the barrier between the primary loop and the secondary loop. Because the pressure of the primary side is less than that of the secondary side, the water and steam will flow into the primary loop if a tube ruptures and react with the graphite fuel elements and the graphite core internals which will result in destruction of the fuel ball, release of radioactivity into the primary loop and increased primary loop pressure. The HTR-10 steam generator tubes are helical tubes with small curvature radius so tube cracks cannot be detected by using eddy current detection for volumetric in-service inspection. This paper describes a leakage detection system and reasons that the crack whose leakage can be detected by the leakage detection system is stable for normal operation loads and SSE loads. Within the crack stability period, all protection actions of the reactor shutdown protection systems could be completed and the intra-tube pressure decreases to a safe level.
