|
摘要
[目的]文章旨在论证严重事故下内陆核电厂具有可靠的水资源安全应对措施。[方法]通过对比内陆核电放射性废液处理结果与国家相关标准,分析了严重事故工况下内陆核电的放射性废液的处理措施,同时提出了进一步提高安全性和可靠性的措施—加强备用电源、备用水源和增加废液存贮水池。[结果]结果证明:严重事故下,通过安全壳包容、核岛厂房滞留、水池暂存三道外层的放射性物质隔离措施,能够将放射性物质在厂内进行"存贮、封堵和处理"。[结论]CAP1000内陆核电具有完善的严重事故预防和事故缓解措施,能够从设计上实际消除大量放射性物质释放的可能性,有能力在严重事故下确保水资源安全。
[Introduction]The paper aims to prove the reliable measures for water resources safety under the serious incident of inland nuclear power plant. [Method]By comparing the treatment results of the radioactive waste liquid in inland nuclear power and the national standards, it analyzed the treatment measures for the radioactive waste liquid under the serious incident of inland nuclear power, meanwhile, put forward the measures in order to further improve the safety and reliability of nuclear station, which were strengthening standby power supply, increasing standby water source and increasing waste liquid storage tank. [Result]The results show that under the serious incident, the radioactive material can be stored, blocked and treated in the plant by three radioactive material isolation measures of the containment holding, nuclear island plant retention and temporary storage in the pool at the plant. [Conclusion]CAP1000 inland nuclear power has perfect incident prevention and mitigation measures, which can effectively eliminate the possibility of releasing a large number of radioactive materials by the design. The inland nuclear power has the ability to ensure the safety of water resources under the serious incident.
