Derating design, as a technology in the research and development process of modern automated industry, plays a great role in the improvement of product design and reliability. Nuclear power plant safety digital control system (DCS) has strict requirements on reliability. In order to meet the corresponding reliability index, it is necessary to carry out derating design in research and development of safety DCS products. Based on the derating design method, the reliability calculation and analysis on some components used in nuclear power plant safety DCS were carried out. The reliability variation of components under different derating grades was studied, and the importance of derating design on reliability improvement of nuclear power plant safety DCS was shown. This research provides some conferences about derating design in the reliability study on the nuclear power.
