Study On Safety-relatedmeasurement Uncertainty In Nuclear Power Plant

Safety-related measurement uncertainty calculation is important to determine appropriate set-points in nuclear power plant design work, which is key to run the nuclear plant safely and economically. There is still no such kind of uncertainty calculation standard for nuclear power plant designers to use in China. This paper shows requirements through national codes to industrial standards and the methodology, along with comparison of the considerations in old and new design way for nuclear power plant, to give the idea about the key elements of uncertainty calculation. It also gives a summary and prospect on this topic.
