Abstract Nowadays, it is necessary to accelerate the construction of new power plant in face of rising energy demand in such a way that the electricity will be generated at the lowest cost while reducing emissions caused by that generation. The expansion planning is one of the most important issues in electricity management. Nuclear energy comes forward with the low-carbon technology and increasing competitiveness to expand the share of generated energy by introducing Gen IV reactors. In this paper, the generation expansion planning of these new Gen reactors is investigated using the WASP software. Iran power grid is selected as a case of study. We present a comparison of the twenty-one year perspective on the future with the development of (1) traditional thermal power plants and Gen II reactors, (2) Gen III + reactors with traditional thermal power plants, (3) Gen IV reactors and traditional thermal power plants, (4) Gen III + reactors and the new generation of the thermal power plant, (5) the new generation of thermal power plants and the Gen IV reactors. The results show that the Gen IV reactors have the most developing among other types of power plants leading to reduce the operating costs and emissions. The obtained results show that the use of new Gen of combined cycle power plant and Gen IV reactors make the emissions and cost to be reduced to 16% and 72% of Gen II NPPs and traditional thermal power plants, respectively.

通过总发电成本和环境影响优化向第四代反应堆迁移在容量扩展规划中的影响

摘要 当前，面对不断增长的能源需求，必须加快新电厂建设，以最低成本发电，同时减少发电排放。扩建规划是电力管理中最重要的问题之一。核能以低碳技术和竞争力不断增强，通过引进第四代反应堆扩大发电量份额。在本文中，使用WASP 软件研究了这些新Gen 反应堆的发电扩展规划。选择伊朗电网作为研究案例。我们将 21 年的未来展望与 (1) 传统热电厂和第二代反应堆的发展进行比较，(2) Gen III + 反应堆与传统热电厂， (3) Gen IV 反应堆和传统热电厂， (4) Gen III + 反应堆和新一代热电厂， (5) 新一代热电厂发电厂和第四代反应堆。结果表明，第四代反应堆在其他类型的发电厂中发展最快，可降低运营成本和排放。所得结果表明，采用新一代联合循环电厂和第四代反应堆，排放量和成本分别降低到第二代核电厂和传统火电厂的16%和72%。结果表明，第四代反应堆在其他类型的发电厂中发展最快，可降低运营成本和排放。所得结果表明，采用新一代联合循环电厂和第四代反应堆，排放量和成本分别降低到第二代核电厂和传统火电厂的16%和72%。结果表明，第四代反应堆在其他类型的发电厂中发展最快，可降低运营成本和排放。所得结果表明，采用新一代联合循环电厂和第四代反应堆，排放量和成本分别降低到第二代核电厂和传统火电厂的16%和72%。
