M310 Nuclear Power Plant Situation Calculation Design Used for Computerized Alarm Inhibition

Operation condition of nuclear power units in the nuclear power plants with digital control system and advanced main control room shall be calculated in real-time by digital instrument controlled system（DCS） and presented to the operator in the main control room by user-friendly digital man-machine interface.The calculated results can be used for the computerized alarm inhibition process.This paper gives the calculation method and its implementation for the design operation condition.
