The utility model discloses an industrial control computer for a nuclear power station, which comprises the following components: a communication module which communicates with a programmable logic controller, a display module which is used for receiving user operation instruction, and a logic module which is used for treating the user operation instruction for transmitting to the programmable logic controller through the communication module. The communication is provided in an independent communication box. The logic module is provided in an individual logic box. The display module is provided in an independent display box. The communication box, the logic box and the display box are in communication connection with each other. The individually sealed communication box according to the utility model can firmly fix a communication interface thereby greatly reducing the probability of inferior communication interface contact caused by opening/closing the door of the switch control cabinet or vibration, and improving the stability and reliability of the industrial control computer.
