福岛核事故对核电站的安全水平提出了更高的要求,原M310堆型核电站仅设计了用于基准事故的氢气浓度监测系统,并未考虑严重事故下的氢气浓度监测,导致严重事故后安全壳内氢气处于持续不可控的状态,严重威胁安全壳的完整性。以某M310堆型核电站为例,对严重事故下安全壳内氢气浓度监测系统进行详细介绍,论证结果表明增加严重事故下氢气浓度监测系统可以极大地提高核电站的安全水平,是有效的、可行的。
Fukushima nuclear power plant safety standards put forward higher requirements, the original M310 reactor nuclear power plant designed only for the baseline accident monitoring of hydrogen concentration, did not take into account the concentration of hydrogen concentration in serious accidents, leading to serious safety after the accident Hydrogen in the shell is in an uncontrollable state, which seriously threatens the integrity of the containment. Taking a M310 nuclear power plant as an example, the hydrogen concentration monitoring system in containment under serious accident is introduced in detail. The results show that the hydrogen concentration monitoring system can greatly improve the safety level of nuclear power plant under the increased serious accident, which is effective and feasible .
