地下核电厂厂房以丘陵地区中等规模山体地形为基础,采用阶地平埋型式对核岛厂房进行总体布置设计。采用将核岛地下厂房布置在“L”型洞室中和将核岛地面厂房布置在山体边坡外侧的布置方案,在此基础上进行地下厂房设备运输及人员通道、管道及电气电缆连接通道,以及地面核岛厂房的总体布置概念设计。对常规地面核岛厂房置于地下后所产生的影响进行分析,认为地下核电厂核岛厂房布置方案合理可行。
Underground nuclear power plant to hilly areas of medium-sized mountain topography as the basis, using terraced buried type of nuclear island plant layout design. The layout of the nuclear island underground plant in the “L” -type cavern and the arrangement of the nuclear island ground plant on the lateral side of the mountain slope are adopted, on the basis of which, underground plant equipment and transportation, personnel access, pipelines and electrical cables Connection channel, and the design concept of the overall layout of the nuclear island plant on the ground. The analysis of the impact of the conventional ground-based nuclear island plant on the ground floor shows that the layout of the nuclear island plant of the underground nuclear power plant is reasonable and feasible.
