Abstract

The pressurised water reactor (PWR) situated on the northern coast of Egypt is one of the world's most advanced nuclear power plants. This study aims to accurately assess the consequences of potential radioactive releases during two hypothetical nuclear accidents, thereby safeguarding individuals and the environment. The Health Physics Simulation Software HotSpot 3.1.2 was employed to model this reactor's two hypothetical accident scenarios (AS1 and AS2). The study introduced and explored the immediate and delayed protective measures related to the effective doses at the pertinent distances concerning AS2. It has been found that increasing the effective release altitude was observed to negatively affect both TEDE and ground deposition, while elevated wind speeds proved to be successful in reducing radioactive harm. Consequently, it is recommended that urgent measures be implemented to safeguard the public from exposure to these pathways in the event of significant radiological incidents, even at considerable distances from the source.

摘要

位于埃及北部海岸的压水反应堆（PWR）是世界上最先进的核电站之一。本研究旨在准确评估两次假设的核事故期间潜在放射性释放的后果，从而保护人员和环境。使用健康物理模拟软件HotSpot 3.1.2对该反应堆的两种假设事故场景（AS1和AS2）进行建模。该研究引入并探讨了与AS2相关距离处有效剂量有关的即时和延迟防护措施。研究发现，有效释放高度的增加对全身有效剂量（TEDE）和地面沉积均产生负面影响，而较高的风速则成功降低了放射性危害。因此，建议采取紧急措施，以便在发生重大放射性事件时，即使在离源相当远的距离，也能保护公众免受这些途径的辐射。
