The Applicability Analysis of Fusion Reactors and China Nuclear Safety Code HAF102

Abstract With the development of ITER project, China is preparing to build China Fusion Engineering Experimental Reactor (CFETR), at present; there is no domestic nuclear fusion regulation framework. The nuclear safety regulation framework based on the fission technology is relatively solid and referable, which can provide reference for the establishment of fusion regulation framework. HAF102 “Safety Code on Nuclear Power Plant Design” is one of the most important regulations in Chinese nuclear safety framework. HAF102 specifies the nuclear safety requirements and provides guidance for the design of fission reactors in terms of defense in depth, safety functions and safety classification, these design principles are also crucial for fusion reactors. Therefore, this paper analyzes the general applicability of fusion reactors and HAF102-2016, identifies the non-conformance terms and categories the terms into generally applicable and partially applicable. The application analysis aims to identify the important safety issues that should be considered in the early stage of the development of fusion reactors, in addition, the inapplicable provisions of HAF102 are identified based on the characteristics of fusion reactors. The analysis lays a preliminary foundation for the establishment of a fusion regulation framework on safety issues in China, and on the other hand, it provides recommendations for the design principles of fusion reactors.
