摘要

本文介绍了比利比诺核电站一次超出设计基础的放射性氢输运事故的模拟结果,并对反应堆腔体和反应堆中央大厅的氢爆炸安全性进行了分析。KUPOL-M代码版本1.10a被用作证明氢气爆炸安全性的计算工具。正在调查的事故是一个超出设计基础的事故,其初始事件是两对自动控制棒的自发移动和反应堆停堆系统的故障。事故导致最大可能的正反应性释放,燃料元件的大规模破坏,以及作为气体混合物的一部分的放射性氢逸出,进入反应堆腔和中央大厅,并进一步通过破碎的窗户进入大气。计算结果表明,反应器内腔和中央大厅内未形成爆炸浓度的氢气。因此,使用EGP-6反应堆的Bilibino核电站机组在整个设计基础事故期间都能保证氢气爆炸安全。

Hydrogen Explosion Safety for the Bilibino NPP EGP-6 Reactor in Conditions of a Beyond Design Basis Accident
The paper presents the results of simulating a beyond design basis accident with regard to radiolytic hydrogen transport and analysis of hydrogen explosion safety in the reactor cavity and in the central reactor hall of the Bilibino NPP. The KUPOL-M code, version 1.10a, is used as the calculation tool for justifying hydrogen explosion safety. The accident under investigation is a beyond design basis accident, the initial event for which is spontaneous travel of two pairs of automatic control rods and a failure of the reactor scram system. The accident leads to the maximum possible release of positive reactivity, mass destruction of fuel elements, and escape of radiolytic hydrogen, as part of the gas mixture, into the reactor cavity and the central hall and further, through the broken windows, into the atmosphere. The calculation results show that no explosive concentrations of hydrogen are formed in the reactor cavity and in the central hall. Therefore, hydrogen explosion safety is ensured throughout the duration of the design basis accident for the Bilibino NPP unit with the EGP-6 reactor.
