Abstract

Abstract

The diversity of I&C system in the offshore small modular reactor is assessed by the standard method of diversity analysis. Aiming at the selection of the platform for the digital I&C system, the diversity quantitative evaluation is conducted by using the method of NUREG/CR 7007, and which provides data support for the selection of the platform for the digital I&C system. The analysis results indicate that the I&C systems of the small modular reactor basically meet the diversity requirements in correlative standards, and are provided with sufficient diversity.
