该除气塔为核安全3级、抗震Ⅰ类的设备。该设备按RCC-M规范(2002版及2002年补遗)3级设备中设计规则的第2种方法进行计算与评定。计算与评定涉及设备在设计工况、正常工况、异常工况和事故工况,各工况下的载荷组合及应力限值列于表1。应力分析使用的程序为ANSYS。该程序在我国核电设备设计分析中的有效性已经得到国家核安全局的认可。评定包括筒体、上下封头、容器支承、接管、法兰和管板的完整计算与评定。分析与评定表明,
The degassing tower for nuclear safety level 3, class Ⅰ earthquake-resistant equipment. This equipment is calculated and evaluated in accordance with the second method of the design rules of Level 3 equipment of the RCC-M specification (2002 edition and 2002 addendum). Calculation and assessment of equipment involved in the design conditions, normal conditions, abnormal conditions and accident conditions, load conditions and stress combinations under various conditions are shown in Table 1. The procedure used for stress analysis is ANSYS. The validity of this program in the design analysis of nuclear power equipment in China has been approved by the National Nuclear Security Administration. The assessment includes the complete calculation and assessment of the cylinder, upper and lower heads, container support, takeover, flange and tube plate. Analysis and assessment show that,
