Abstract

PURPOSE:To suppress the rise of the nuclear furnace pressure by installing a load cut-off control means and simultaneously starting the operation of a steam flow rate adjusting valve and a bypass flow rate adjusting valve and relatively adjusting the operations of the both adjusting valves by a relative adjusting means for the valve opening/closing. CONSTITUTION:A turbine controller 5 receives the pressure Pt equal to the nuclear reactor pressure Pr and the speed 12 of a power generator 8 and is constituted of circuit systems (101-104, 106) for obtaining the all steam flow rate signal 109 and circuit systems (116-118, 124) for obtaining each speed load demand signal, and soon. Each opening degree signal of a main steam flow rate adjusting valve 10 and a bypass steam flow rate adjusting valve 11 is outputted. In this case, analogue switches 20 and 21 for selecting 0% in the case when a load cut-off detection signal A is established are installed. The variation rate limitter 122 for restricting the opening speed of the main steam flow rate adjusting valve 10 and a variation rate limitter 100 for matching the closing speed of the bypass steam flow rate adjusting valve 11 to the opening degree of the main steam flow rate adjusting valve 10 are installed.
