The utility model provides a nuclear power plant steam generator steam flow limiter used to reduce pressure losses of the steam flow limiter. 19 Venturi tubes are arranged in a steam outlet pipe mouth. The 19 Venturi tubes are arranged as the following mode that one Venturi tube is arranged on a center; the 6 Venturi tubes are arranged on an intermediate circle; the 12 Venturi tubes are arranged on an outermost circle. Compared to the traditional steam flow limiter, by using the nuclear power plant steam generator steam flow limiter of the utility model, the pressure losses are small; an outlet steam pressure of the steam generator can be increased so that economical efficiency is increased.
