Abstract: When nuclear power plants experience severe accidents triggered by external event or catastrophic natural disasters beyond design basis accident, there is a need for off-site emergency response forces to provide support. The mutual support among nuclear power groups serves as an important backup force. Based on the analysis of the emergency response capabilities layout among domestic nuclear power groups and drawing from the practices of international support for nuclear accident emergency in other countries, this paper identifies current issues in inter-group emergency support for nuclear accident. This paper also explores comprehensive considerations necessary for implementing mutual support among groups, coordination and cooperation with national-level nuclear emergency support forces, and requirements for routine maintenance of the support mechanism. Relevant suggestions are proposed.

Key words: nuclear emergency, emergency support, mechanism, nuclear power group
