Embodiment Construction
[0067] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0068] The signal distribution method of the digital instrument and control system of the nuclear power plant in the embodiment of the present invention, on the basis of the qualitative evaluation method, introduces the reliability technology based on the quantitative evaluation of probability risk to detect the signal distribution / grouping of the digital instrument and control system of the nuclear power plant to guide The design of decentralized control and function allocation of the digital I&C system reduces the probability of increasing the risk of core fusion (CDF) and large radioactive leakage (LRF) accidents in nuclear power plants due to unreasonable allocation / grouping, and reduces the risk of system failure due...
