脉冲堆事故分析

Accident Analysis for Pulsed Reactor

本文介绍了脉冲堆两个最大假想事故——堆水池失水并使堆芯裸露和脉冲棒误发射事故分析结果。对于堆水池失水并使堆芯裸露事故,只要能及时停堆,无需采取任何其他措施,则能保证反应堆的安全。事故过程中,燃料芯体和包壳温度都不会超过840℃。在稳态额定功率下脉冲棒误发射事故过程中,反应堆峰功率达4800MW,燃料温度峰值为950℃,反应堆也是安全的。

This report presents analysis results of two maximum postulation accidents for pulsed reactor with 1MW steady-state power. Calculation show that reactor is safety for loss of pool water and core exposed. In the course of this accident, as long as reactor is shuted down timely,fuel meat and cladding peak temperature are lower than 840℃. Analysis show that reactor is still safe for pulsed rod mistake projection accident under 1MW steady-state power, Pulsed peak power reaches 4800MW and fuel meat peak temperature reaches 950℃ in the course of this accident.
