摘要

WWR-M研究堆的辐射影响是可能的,因为放射性物质释放到环境中,这是在运行和退役期间产生的。运营商的责任之一是采取措施避免或优化放射性废物的产生和管理,以尽量减少对环境的总体影响。气体和空气传播的废物通过通风和空气净化系统释放到环境中,这是整个反应堆设计的要点。防止放射性污染向环境扩散的主要方法是结合设计良好的通风系统,彻底清洁排出的空气。分析了大气气溶胶排放的源项,介绍了现有的辐射控制系统和专用通风系统,并对大气气溶胶的实际排放进行了分析。估算了计划拆除反应堆活动期间的气体-气溶胶排放总量。现有系统的充分性和有效性,以确保所需的反应堆安全水平。

Radioactive gaseous-aerosol releases from the WWR-M research reactor
The radiation impact of the WWR-M research reactor is possible due to the release of radioactive substances into the environment, which are generated during both operation and decommissioning. One of the operator's responsibilities is to take measures to avoid or optimize the generation and management of radioactive waste to minimize the overall impact on the environment. Gaseous and airborne wastes are released into the environment through ventilation and air cleaning systems, which are essentials of the overall reactor design. The main method for preventing radioactive contamination spread to the environment is the combination of a well-designed ventilation system having thorough cleaning of the exhaust air. An analysis of the source terms of the gaseous-aerosol emissions, a description of the existing radiation control system and special ventilation system, and an analysis of the actual gaseous-aerosol emissions are presented. The total amount of gaseous-aerosol emissions during the planned reactor dismantling activity is estimated. The sufficiency and effectiveness of the existing system to ensure the required level of reactor safety are shown.
