海上浮动核电站应急撤离分析

Preliminary Analysis of Emergence Evacuation for Floating NPPs

核事故应急撤离是核应急响应的重要组成部分,目的在于快速有效地将可能受到事故影响的人员转移至安全地区。本文根据海上浮动核电站的运行场址与运行特点,对海上浮动核电站应急响应特征进行分析,给出了浮动核电站应急等级划分和应急计划区范围。结合陆地核电站场区撤离与海洋平台撤离疏散方法,制定了海上浮动核电站应急撤离情景与撤离分析假设。对浮动核电站人员撤离的分析结果表明,浮动核电站人员撤离满足客船撤离要求,及海上浮动核电站应急撤离的时间要求。

Emergency evacuation of nuclear accidents is an important part of nuclear emergency response, with the aim of quickly and effectively transferring people who may be affected by the accident to safe areas. In accordance with sites and operation properties, the emergency response characteristics of floating NPPs at sea are analyzed, and corresponding emergency level classification and emergency planning zone scope are provided. Combined with 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 NPP personnel indicates that the evacuation requirements of passenger ships and the time requirements for emergency evacuation for floating NPPs are met.
