Key Technology of ACP100: Reactor Core and Safety Design

Abstract

Small modular reactor is a new kind of nuclear energy system. The ACP100 is a multi-purpose modular small PWR with full intellectual property in China. This paper introduces the research and development process, the main characteristics of the reactor core and safety design technology, mainly including the nuclear design, thermal-hydraulic design, safety design concept, inherent safety design, and the strategy for accidents. Through the combination of the deterministic theory and the probabilistic safety assessment, the safety of ACP100 is greatly improved and exceeds the Generation 3 nuclear power plant safety standards.
