The utility model discloses a steam generator sewerage system self-inspection and waste heat utilization system which comprises a reactor pressure vessel and a steam generator, and a reactor coolant channel is arranged between the reactor pressure vessel and the steam generator. A generator water supply pipeline, a generator steam pipeline and a generator blow-off pipeline which are communicated with the interior of the steam generator are arranged on the steam generator, a flowmeter and a temperature sensor are arranged on the generator blow-off pipeline, and a first heat exchanger is arranged at the end, away from the steam generator, of the generator blow-off pipeline; according to the utility model, the flow meter and the temperature sensor are arranged on the blow-off pipeline of the generator, so that the internal temperature and flow of the blow-off pipeline of the generator can be monitored in real time, and whether the blow-off system works normally or not can be judged; waste heat of the steam blow-
