摘　　要：本文以田湾核电站事故场外后果评价系统TW-NAOCAS中的剂量与干预模块为例,介绍核事故后果评价中的剂量与早期干预评估模式及一个算例。剂量估算模式主要给出估算潜在剂量、正常生活剂量与事故释放后2天的预期剂量的模式;干预措施评估模式主要涉及相应于设计基准事故(DBA)与超设计基准事故(BDBA)的各类干预措施(隐蔽2天、撤离7天、服碘片)的可避免剂量的估算模式,此中考虑了撤离途径的附加剂量。最后介绍了程序验证与实例计算结果。The models of estimating dose and assessing early intervention evaluation presented based on the dose and intervention model in accident off-site consequences assessment system TW-NAOCAS for Tianwan NPP. The dose estimating models axe mainly models calculating potential dose, normal living dose and projected dose after 2 days from accident release. The intervention assessment models contain mainly the models to calculate avertible dose of each intervention measure （such as 2 days-sheltering, 7 days-evacuation and administration of iodine tablets） corresponding Design-Base Accident （DBA） and Beyond Design-Base Accident （BDBA） in which the additional dose has been considered for evacuation pathway. Finally a program test and example calculation axe introduced.
