摘　　要：针对突发断电事故下的核主泵惰转工况,基于额定参数提出惰转转速与惰转流量特性曲线计算模型,并通过100D型核主泵惰转试验数据对推导的模型予以验证。结果表明,该计算模型可用于核主泵初步设计计算和验证分析。基于该模型进一步得到了核主泵惰转设计准则,并验证了AP1000核主泵设计转动惯量。For a sudden loss of power in reactor coolant pump （RCP） ,a calculation model of rotor speed and flow characteristics based on rated parameters was studied . The derived model was verified by comparing with the power-off experimental data of 100D RCP .T he results indicate that it can be used in preliminary design calculation and verification analysis .Then a design criterion of RCP was described based on the calcula-tion model .The moment of inertia in AP1000 RCP was verified by this criterion .
