Abstract: Emergency evacuation of nuclear accidents is an important part of nuclear emergency response, with the aim of quicklyand effectively transferring people who may be affected by the accident to safeareas. In accordance with sites and operation properties, the emergency responsecharacteristics of floating NPPs at sea are analyzed, and corresponding emergency level classification and emergency planning zone scope are provided. Combinedwith the evacuation for land NPP sites and the evacuation method of offshore platforms, the emergency evacuation scenarios and evacuation analysis hypotheses of floating NPPs at sea were formulated. The evacuation analysis of floating NPPpersonnel indicates that the evacuation requirements of passenger ships and thetime requirements for emergency evacuation for floating NPPs are met.

Key words: Floating NPP, Nuclear emergency, Emergency planning zone, Emergence response, Emergence evacuation
