本文主要分析压水堆在次临界或低功率下发生的失控提捧事故的瞬态特性。研究了温度反应性系数,失控反应性引入率,初始功率水平和有效缓发中子份额对事故瞬态特性的影响。
This paper mainly analyzes transient characteristics of PWRs in the event of a loss of control of a sub-critical or low-power reactor. The effects of temperature reactivity coefficient, rate of uncontrolled reactivity introduction, initial power level and effective delayed neutron fraction on transient performance were investigated.
