【《瑞士原子能协会通报》1995年第10期第10页报道】 瑞士保罗·舍雷尔研究所(PSI)安全和事故研究实验室(LSU)正在分析核电厂的假想严重事故的过程,全部冷却措施失灵导致反应堆堆芯被毁的事故也在此分析之列。在该事故发生数小时后,反应堆压力容器半球形底壳下部生成温度约2400℃的熔化物,从而使压力容器发生故障。研究压力容器如何发生故障,这对于了解故障的进一步演变具有重要意义,因为这种故
[ASA Bulletin, 1995, No. 10, p. 10] The Swiss Institute of Safety and Accident Research Laboratory (LSU) at the Paul Scherer Institute (LSI) is analyzing the process of a hypothetical and serious accident at a nuclear power plant. All cooling The failure of measures to cause the reactor core to be destroyed is also analyzed here. A few hours after the accident, a melt at a temperature of about 2400 ° C was generated in the lower part of the hemispherical bottom of the reactor pressure vessel, thereby causing failure of the pressure vessel. Studying how a pressure vessel breaks down is of great importance for understanding the further evolution of the failure because of this
