Abstract

On September 2021, Polish government declared that six pressurized water reactors with combined capacity of 6–9 GWe will be built by 2040 to reduce Poland’s reliance on coal. Due to the adopted schedule, construction of the first nuclear power plant will begin in 2026, with the first reactor capacity of 1–1.6 GWe to be operational in 2033. The Polish authorities announced in 2022 the selection of two locations and technologies for Poland’s first commercial nuclear power plants. Westinghouse AP1000 reactor was selected by Polish government to be built as the first plant in the location of Lubiatowo-Kopalino, on the coast of the country. In the meantime, Poland’s ZE PAK, Polska Grupa Energetyczna, and Korea Hydro & Nuclear Power have signed the letter of intent to collaborate on the project that evaluates the feasibility of building South Korean APR1400 on Pątnów site in central Poland. The objective of this study was to acquire and examine the gaseous effluents released during the standard operation of the AP1000 and APR1400 reactor technologies, with the primary goal of focusing on estimating the potential exposure of the general public. The effluents were calculated by using the GALE code based on each nuclear reactor technical specification. The obtained results were compared with those included in the Design Control Document for each reactor. Subsequently, the HotSpot software was used to calculate the radiation risk for downwind areas by utilizing GALE code results as source terms together with specific meteorological data corresponding for each localization. The results for AP1000 at Lubiatowo-Kopalino site and for APR1400 at Pątnów site were analysed and compared in the study. As the study findings were evaluated with the Polish radiation limits for the general public, all doses remained below the legal thresholds. With no previous alike studies conducted, this research begins the analysis of radiation impacts associated with the planned nuclear power plant in Poland during normal operation.

常规运行期间气体排放的定量评估：波兰 Lubiatowo-Kopalino 和 Pątnów 核电站规划比较研究

2021 年 9 月，波兰政府宣布将在 2040 年之前建造 6 座总容量为 6-9 GWe 的压水反应堆，以减少波兰对煤炭的依赖。根据已通过的时间表，第一座核电站将于 2026 年开工建设，首座反应堆的发电能力为 1-1.6 GWe，将于 2033 年投入运行。波兰当局于 2022 年宣布了波兰首座商业核电站的两个选址和技术。西屋 AP1000 反应堆被波兰政府选中，将作为第一座核电站建在该国沿海的 Lubiatowo-Kopalino 地区。与此同时，波兰 ZE PAK 公司、波兰能源集团（Polska Grupa Energetyczna）和韩国水电与核电公司（Korea Hydro & Nuclear Power）签署了项目合作意向书，对在波兰中部 Pątnów 建造韩国 APR1400 核电站的可行性进行评估。这项研究的目的是获取并检查 AP1000 和 APR1400 反应堆技术在标准运行期间释放的气体流出物，主要目标是估算公众可能受到的辐射。根据每个核反应堆的技术规格，使用 GALE 代码计算流出物。获得的结果与每个反应堆的设计控制文件中的结果进行了比较。随后，使用 HotSpot 软件计算下风向地区的辐射风险，将 GALE 代码结果作为源项，并结合与每个地方相应的具体气象数据。研究分析并比较了 Lubiatowo-Kopalino 现场的 AP1000 和 Pątnów 现场的 APR1400 的结果。由于研究结果是根据波兰公众辐射限值进行评估的，因此所有剂量都低于法定阈值。由于之前没有进行过类似的研究，这项研究开始分析波兰计划中的核电站在正常运行期间的辐射影响。

期刊介绍： Science and Technology of Nuclear Installations is an international scientific journal that aims to make available knowledge on issues related to the nuclear industry and to promote development in the area of nuclear sciences and technologies. The endeavor associated with the establishment and the growth of the journal is expected to lend support to the renaissance of nuclear technology in the world and especially in those countries where nuclear programs have not yet been developed.
