| 摘 要： | CANDU6核电厂早期设计未考虑严重事故对策,在严重事故下,CANDU6核电厂的安全壳容易失效。为了解决这一问题,本文研究了无过滤安全壳通风模式对CANDU6核电厂安全壳的影响。本文选取典型的全厂断电严重事故,利用重水蒸气回收系统作为无过滤安全壳通风的路径,初步研究了该通风模式下对安全壳完整性的保持和对裂变产物源项的滞留能力。研究表明:该通风模式可以有效保持安全壳的完整性,同时,对裂变产物源项也有一定的滞留能力。

| Abstract: | Severe accident countermeasure are not considered in early design of CANDU6 nuclear power plant.While severe accident is initiated,containment will be failed.In order to solve this problem,this paper studies the influence of unfiltered containment ventilation on containment of CANDU6 nuclear power plant.Typical station blackout accident(SBO)of CANDU6 nuclear power plant(NPP)is chosen,and the heavy water vapor re⁃covery system was used as the ventilation path of unfiltered containment.The preservation of the integrity of the containment and the retention of the source term of fission products under the ventilation mode were prelim⁃inarily studied.The analysis results indicate that under this ventilation mode,the integrity of the containment can be effectively maintained and the source term of fission products can be retained. |
