F = K1K2G,
где K1 - газотермодинамический коэффициент, определяемый по известным зависимостям, исходя из оптимального соотношения между критическим (аварийным) расходом и сопротивлением вставки в номинальном режиме;
K2 - задаваемый расчетный коэффициент неравномерности паровой нагрузки по длине парогенератора;
G - расход пара через патрубок в номинальном режиме.1. The steam generator of a dual-circuit nuclear power plant, comprising a horizontal housing with a tube bundle of a primary coolant and a device for removing steam of the second circuit in the form of steam outlet pipes installed along the housing in its upper part and connected to at least one steam collector, characterized in that at least one Laval nozzle insert is installed in each steam outlet, the minimum cross section of which is selected by the formula
F = K 1 K 2 G,
where K 1 is the gas thermodynamic coefficient, determined by the known dependencies, based on the optimal ratio between the critical (emergency) flow and the insert resistance in the nominal mode;
K 2 - set calculated coefficient of unevenness of the steam load along the length of the steam generator;
G - steam flow through the pipe in nominal mode.
